201208883 六、發明說明： 【先前技術】 具有-或多個結構化表面之物件用於多種應用（例如， 磨盤、汽車零件之總成及拋棄式吸收物件）中。該等物件 可提供為展現（例如）增加之表面區域、機械緊扣 學性質之薄膜。 亦被稱為卡鉤及纏圈扣件之機械扣件通常包括具有用作 卡釣部件之纏圈喷合頭的複數個緊密間隔之直立突出物，. 且纏圈部件通常包括複數個編織纏圏、非編織纏圈或針織 纏圈。機械扣件在眾多應用中用於提供可釋放附接。舉例 而呂，機械扣件廣泛用於可穿戴拋棄式吸收物件中以圍繞 人的身體緊扣此等物件。在典型組態中’附接至紙尿布或 失禁外衣（inc〇ntinence garment)之後腰部部分的緊扣凸片 ^之鉤條或補片（例如）可緊扣至前腰部區上的_材料之 =區’或鉤條或補片可在前腰部區中緊扣至紙尿布或失 :夕f之底層薄片(例如’非編織底層薄片）。機械扣件亦 =如衛生巾之拋棄式物件。衛生巾通常包括意欲置放 將於穿用者之内衣之底層薄片。底層薄片可包含用以 Γ牢固地附接至内衣之卡釣扣件元件，該内衣與卡 釣扣件元件機械地嚙合。 鉑=緊扣系統之卡鉤可形成為具有彎曲形狀，或該等卡 二° 經變形以包括(例如)呈蘑菇形狀之 :纏:有變化程度之通用性及複雜性之-些方法可用以控 帝J纏圈嗜合J_开彡# 貝形狀。參看（例如）美國專利第3，192,589號 157086.doc 201208883 (Pearson);第 5,953,797 號（Provost等人）；第 6，132,660 號 (Kampfer)，·第 6,558,602 號（Melbye 等人）及第 6,708,378 號 (Parellada等人）以及美國專利申請公開案第2002/0124359 號（Murasaki 等人）。 卡鉤及纏圈緊扣系統可包括至少兩個哺合強度特性：剝 落強度及剪切強度。剝落強度對應於藉由向上剝落一緊扣 部件且使其遠離另一緊扣部件而使緊扣部件彼此脫齧所需 要之力。剪切強度對應於藉由在平行於緊扣部件之平面上 拉動緊扣部件中之至少一者使其遠離另一緊扣部件而使緊 扣。卩件彼此脫蓄所需要的力。通常’緊扣部件在剪切方面 之喷合強度高於緊扣部件在剝落方面之嚙合強度。 在使用者希望分離卡鉤與纏圈緊扣部件（例如，在諸如 紙尿布之吸收物件上）時，使用者通常會剝開緊扣部件。 可剝開緊扣部件之容易性會影響使用者對緊扣部件之間的 附接之可靠性的感知。舉例而言，在護理者自嬰兒身上移 除紙尿布時，若鉤條感覺好似極容易自紙尿布之纏圈搭接 區或底層薄片剝落，則護理者可能會懷疑緊扣部件在使用 時能有多好地保持紙尿布密封。且在一些例子中，在紙尿 布穿舊了時’低泰J落強度可導致緊扣部件之無意分離。 儘管卡鉤及纏圈緊扣技術中存在進展’但在緊扣部件之 間的附接之可靠性（不論實際的或感知的）方面的增強將為 需要的。 【發明内容】 本發明提供__種方法，其用於容易地改變結構化表面上 157086.doc 201208883 之直立元件上之遠端頂蓋的形狀。此等遠端頂蓋可為（例 如）機械扣件之纏圈嚙合頂蓋《該方法包括使機具在直立 元件之鄰近列之間穿過，使得該機具接觸該等遠端頂蓋中

Description of the Invention: [Prior Art] Objects with - or multiple structured surfaces are used in a variety of applications (eg, grinding discs, assembly of automotive parts, and disposable absorbent articles). Such articles may be provided as films which exhibit, for example, increased surface area and mechanical fastening properties. Mechanical fasteners, also known as hooks and loop fasteners, typically include a plurality of closely spaced upright projections having a whirling head for use as a snap-on component. And the wrap-around component typically includes a plurality of woven wraps, non-woven wraps, or knitted wraps. Mechanical fasteners are used in a variety of applications to provide releasable attachment. For example, mechanical fasteners are widely used in wearable disposable absorbent articles to hold the objects around the human body. In a typical configuration, a hook or patch (for example) of a fastening tab of a waist portion attached to a disposable diaper or an incontinent garment can be fastened to the material of the front waist region. The = zone' or the hook strip or patch can be fastened to the disposable diaper in the front waist region or the underlying sheet (eg, 'non-woven underlying sheet). Mechanical fasteners are also = disposable items such as sanitary napkins. Sanitary napkins typically include an underlying sheet intended to be placed on the wearer's undergarments. The bottom sheet may comprise a snap fastener element for securely attaching to the undergarment, the undergarment being mechanically engaged with the snap fastener element. The hooks of the platinum=fastening system may be formed to have a curved shape, or the cards may be deformed to include, for example, a mushroom shape: wrap: the degree of versatility and complexity of the change - some methods may be used Control Emperor J wrapped circle hobby J_ Kailuan # 贝形. See, for example, U.S. Patent No. 3,192,589, 157086. Doc 201208883 (Pearson); 5,953,797 (Provost et al.); 6,132,660 (Kampfer), pp. 6,558,602 (Melbye et al.) and 6,708,378 (Parellada et al.) and U.S. Patent Application Publication No. 2002 /0124359 (Murasaki et al.). The hook and loop fastening system can include at least two feeding strength characteristics: peel strength and shear strength. The peel strength corresponds to the force required to disengage the fastening members from each other by peeling off one of the fastening members upwardly and away from the other fastening member. The shear strength corresponds to being tightened by pulling at least one of the fastening members parallel to the fastening member away from the other fastening member. The force required to remove the pieces from each other. Usually, the snap-on strength of the fastening member is higher than the engagement strength of the fastening member in terms of peeling. When the user desires to separate the hook and the loop fastening component (e.g., on an absorbent article such as a disposable diaper), the user typically peels off the fastener component. The ease with which the fastener elements can be peeled off can affect the user's perception of the reliability of the attachment between the fastener components. For example, when the caregiver removes the disposable diaper from the baby, if the hook feels as if it is easily peeled off from the looped area or the underlying sheet of the disposable diaper, the caregiver may suspect that the fastening component can be used while How well to keep the paper diaper sealed. And in some instances, the low strength of the diaper can cause unintentional separation of the fastener components. Despite advances in the hook and loop fastening techniques, enhancements in the reliability (whether actual or perceived) of the attachment between the fastening components would be desirable.

Referring now to Figure 4, a plurality of implements 25 (pins as shown) are shown between a plurality (four) of the upright members on the thermoplastic backing 14. The use of multiple needles allows the distal cap 12 to be simultaneously shaped in a single column. A plurality of implements can be self-aligned between the plurality of columns of upstanding members on the thermoplastic backing 14, such as by the taper of the tip of the needle and the flexibility of the needle to self-align. In Figure 4, an array of multiple implements 25 is shown positioned in an erect element: between the columns 'for at least a portion of the thermoplastic backing' and the distal end cap 12 of the female row is on each side Contact, but it is expected that 'not every column of the distal cap 12 needs to be contacted by the implement to produce 157086. Doc •12- 201208883 Useful structured surface. For example, the implement can be placed between every other column or every three columns. Alternatively, a plurality of sets of implements can be used to process multiple columns of upstanding elements in a segment or partition, while adjacent segments or partitions can remain untouched by the implement. Alternatively, different sections or sections of the upstanding elements on the thermoplastic backing 14 may be contacted by implements having different sizes or shapes. Thus, the shaping of the distal cap 12 in the structured surface can be tailored to the needs of the application. In Fig. 4, the plurality of implements 25 claim that at least some of the implements have different lengths or otherwise positioned such that the tips of the implements are not aligned with one another. This situation is not a requirement, and in some embodiments, the tips of the implements can be aligned with each other. In the illustrated embodiment, as multiple implements pass between multiple columns, each distal cap 12 will be contacted by only one implement at a time, but the sides of the distal cap 12 will be sequentially contact. In this embodiment, the distal end cap 12 can be prevented from being pinched by simultaneous contact with both sides, which may be advantageous for some applications. In some embodiments of the embodiments described above, the implement is tapered. Figure 5 illustrates a distal end cap 12 of two adjacent columns of an upright member having a tapered tip. The overhanging portion of the stem of the upright member - in the embodiment of Fig. 5, the tapered portion of the implement 35 is adapted to be adjacent the 歹J of the upright member to contact the distal cap 12. For example, in the embodiment in which the thermoplastic backing 14 is used to achieve the shaping effect/monthly implement 35 does not need to be touched, the implement is a shimming sheet or a shimming sheet, a polymer shimming sheet or The shim of any suitable shape is made of any suitable material. If the shim is reproducible, then 157086. Doc -13- 201208883 A plurality of shims passing between multiple columns can be self-aligned between the columns of erect elements. In the view shown in Figure 6, the shims 45A or 45B are passed between the columns of erect elements that are visible to the viewer and the columns of erect elements that are invisible to the viewer. The shim 45A is shown with the shim 45 placed perpendicular to the orientation of the thermoplastic backing 14, with one edge of the crucible being flat against or adjacent to the thermoplastic backing 14. The shims 45B are shown with the shims 45B placed at an angle to the thermoplastic backing 14, with only the corners of the shims 45B passing between adjacent columns of erected pieces. Suitable shims that can be used to carry out the present invention include standard gauge gauges that can be tapered or have parallel sides. In some embodiments, including the embodiments described above, the implement is not cut through the thermoplastic backing. In some of these embodiments, the tool is not cut through the thermoplastic backing in an intermittent manner such that a slit interrupted by the backed bridge region is formed. In some embodiments, the implement is not partially cut into the thermoplastic backing. As mentioned above, in some embodiments, the implement does not even need to touch the thermoplastic backing. However, in other embodiments, the implement can be a blade (eg, a rotary cutter) that can cut through or partially cut the thermoplastic back while shaping the distal cap of the upstanding member on the thermoplastic backing lining. In some embodiments, the interrupted slit is cut into the thermoplastic backing by means of a implement (e.g., a rotary cutter) between some pair of adjacent columns of the upright members. The intermittent slit is broken by the complete bridging interval of the backing. The bridge area is the area that is not cut through the backing, and the bridge areas are collinear with the discontinuous slit. The discontinuous slit can be linear in the same direction as the direction of the plurality of columns. Intermittent slit 157086. The portions of the backing on either side of doc-14-201208883 are generally contiguous and are not spaced apart after the rotary cutter passes between the plurality of columns of upright members. The interrupted slits may be completely cut through the thickness of the thermoplastic backing, or the interrupted slits may be partially cut between the adjacent pairs of the upright members on the first surface of the thermoplastic back (also #立立元件自It stands out in the same surface). Some slits can be as much as 5%, 10%, 20%, 30%, 40%, 5〇%. 70/. , 80% or 90% of the extent (for example, in the range from 4% to the extent) penetrates the thickness of the backing. In addition, the thermoplastic backing in the unbroken bridging zone may be present or a portion of the deep cut may be present in the thermoplastic backing in the bridging zone. The portions of the deep cut do not extend through the thickness of the backing and are collinear with the inter: slit . Partial depth cut π can penetrate into the thickness of the back view by up to 5%, jump, 2 ()%, 鸠, Na, Guan, 60%, 7G%, 嶋 or 9G%. The interrupted slits can be positioned between every other column of the upright members of the upright members, or in other patterns that can be spaced apart or unevenly spaced as needed. For such implementations including bridging zones, the bridging zones may be aligned or staggered in a direction perpendicular to the direction of the discontinuous slits. The bridging regions may be staggered such that one of the interstitial slits is substantially located between the inter-t positions between the (four) regions in the adjacent discontinuous slits. When the bridge area is misplaced in this manner, the number of bridge areas necessary to dispose of the structured surface as an integrated unit is minimized. Moreover, various lengths of the bridging regions may be useful for any of these embodiments including bridging regions. In some embodiments, any bridging zone between the adjacent columns has up to 5% of the length of the backing (in some 157086. Doc •15- 201208883 In the examples, the combined length of 40%, 301⁄4, 25%, 20%, 15% or 10%). In some embodiments, in order to maximize the ability of the hook to bend, it may be desirable to minimize the combined length of the bridge. Minimizing the combined length of the bridging regions can be minimized by minimizing the length of any particular bridging region or maximizing the distance between the bridging regions. In some embodiments, the length of a bridging region is greater. Up to 3 mm, 2 mm or 1. 5 mm and at least 0. 25 mm, 0. 5 mm or 0. 75 mm. In some embodiments, the number of bridge zones is up to 1. 5 /cm, 1. 25 /cm, ι·〇 /cm, 0. 75 /cm, 0. 60 / cm or 0. 5 / cm. For example, the distance between the bridges can be at least 0. 75 cm, 1. 0 cm, 1. 25 cm, 1. 5 cm or 1. 75 cm. In addition, the length of the intermittent slit or partial slit between the bridging zones can be adjusted and this length is typically selected to maximize the distance between the bridging zones. In some embodiments, the length of the intermittent slit or partial slit between the bridging zones is at least 8 (in some embodiments, at least 1 〇 111111, 12111111, 14111111, 15 mm, 16 _, 17 mm) , 18, 19 or 2). In some embodiments, a portion of the slit is cut between the adjacent pairs of the upright members by a implement ("Rotor") in the thermoplastic back. The slit can be in the same direction as the plurality of columns. A linear knife slit in the direction of up to 5 〇 / 〇, 10 〇 / 〇, 2 〇〇 / 〇, 30%, 6 〇 / 〇 70%, 80% or 90% (for example In the range from 4〇% to 90/ί>), it is the best way to wear it. When a portion of the slit penetrates the thickness of the lining in a dry circumference from 40% to 90, a portion of the slit allows a singularity between adjacent columns of the upright members. The f is curved, but the backing does not break easily. In an embodiment, a portion of the slit is from 50% to 90%, from 50% to 157086. Doc 201208883 85%, from 55% to 85%, from 60. /.

For any of the embodiments in which the implement is a blade that provides a discontinuous slit or a partial slit in the thermoplastic backing, the structured surface can be in the form of a roll to suit the desired application (eg, for mechanical tightening) The size of the buckle is cut from the roll. The bridging zone that interrupts the intermittent slits allows the structured surface to be treated as an integrated unit. Similarly, because a portion of the slit does not extend through the thermoplastic backing, the structured surface can be disposed as an integrated unit. The bridging zone in any of the embodiments containing bridging zones or the uncut portion of the backing in embodiments having partial slits allows for the disposal of structured surfaces made in accordance with the present invention and/or in accordance with the present invention The form of the roll JL is converted when needed. In some embodiments, the full slit is cut into the thermoplastic backing by some implement between the pair of adjacent elements of the upright member (eg, a 'rotary cutter') (also X through the entire backing thickness). In an embodiment, the structured surface is often joined to «as part of a detailed line as follows. The slits may be linear and self-dipping in the direction of the columns, and the edges extend to the bottom edge of the backing to form a separate contiguous strip of thermoplastic backing on the carrier.

The overhanging portion of the distal cap in the method and structured surface according to the present invention is typically "wrapped." The term "wrapped ring" as used herein relates to the force of attachment of an upright member on a structured surface as disclosed herein to a looped material. The ability to wrap and define the entanglement of the upright elements can be achieved by using standard woven, non-woven or needle materials. In combination with the wrap-around material, the region having the entangled element of the wrap-around county, the erect element of the distal cap, generally provides a higher spalling strength and a dynamic shear of the southern part of the head than the unwrapped (four) head. At least one of strength or higher dynamic friction. A distal cap erect element having a "wrapped meshing overhang" and a "wrapped meshing head" does not include ribs that are precursors to the hooking element (eg, elongated ribs, the ribs The profile is extruded and then cut after stretching in the direction of the ribs to form a hook element). These ribs will not be able to twist the loop before being cut and stretched. Typically, an upright member having a distal cap with a wrap-around overhang has up to about 丨 (in some embodiments, 0. 9, 0. 8 ' 0. 7, 0. 6, 0. 5 or 0. 45) The maximum thickness of the millimeter. In general, an upright member having a wrap-around engaging head has a distal cap shape that is different from the shape of the rod. For example, the upright element can be in the shape of a mushroom (e.g., having a rounded or elliptical head that is enlarged relative to the rod), a hook, a eucalyptus, a nail, a τ, or a j. In some embodiments, the thermoplastic backing has an X direction and a y direction orthogonal to the x direction.

In some embodiments, the distal cap has an overhang that extends beyond the stem on all sides. In some embodiments, the erect element comprises a stem having a mushroom head prior to treatment by the methods disclosed herein (eg, the distal cap is circular prior to passing the implement between two adjacent columns) Or oval). The distal cap may also be angular (e.g., initially having a square or diamond shape prior to passing the implement between two adjacent columns). In some embodiments, the overhanging portions that extend beyond the stem on all sides are substantially equal in volume (e.g., a circular or square distal cap). The volume of material on all sides of the rod may be equivalent, substantially equal in volume to the stomach. However, as will be understood by those of ordinary skill in the art, there may be some variability due to the procedure for fabricating the erect elements on the backing as described above.

In other embodiments, the implement is pushed between adjacent columns of upright members. In such embodiments, the method generally results in the overhanging portion in contact with the implement being bent upwardly away from the thermoplastic backing. In some embodiments, the implement is stationary and pulling the thermoplastic backing under the implement depends on whether pulling the thermoplastic backing results in a greater degree of upward or downward movement relative to the top end cap, in contact with the implement The overhanging portions can be individually bent away from the thermoplastic backing or bent downward toward the thermoplastic backing. In addition to the specific implementations described above, the implement can be any suitable shape that can be fitted between two adjacent columns of upright members 4. The implement can be, for example, a rigid wire or needle having a circular cross section (e.g., a guitar string) or a rigid wire or needle having a non-circular cross section. The implement should generally be large enough (i.e., of appropriate thickness or diameter) to contact the overhanging portion of the distal cap without excessively pushing the stem. The maximum thickness or diameter of the implement can be the spacing between the rods. This spacing is generally greater near the distal cap than at the proximal end attached to the thermoplastic backing. The method according to the present invention is useful in the case of various pin densities (up to 70 erects) because, for example, the diameter or thickness of the implement can be adjusted for different pin densities.

By grasping the device with handle H5, the method according to the invention can be applied to the structured surface. As described above, the length of the needle 125 can be adjusted. For example, the needle can extend beyond the rubber sheet 1〇5 to 〇5. It is possible that the claws are at a loss of cm, in some embodiments, up to 1 cm to other methods for positioning the implement. For example, the template structured surface can have an upright stem or ridge on the thermoplastic backing. The structured surface can be prepared, for example, by profile extrusion (e.g., using a method similar to that described in U.S. Patent No. 4,894, Ne Stegard). The implement can be placed between the bar or the ridge. Advantageously, the method according to the invention does not require a heating implement, an upright element or a thermoplastic backing. Surprisingly, the method according to the invention results in permanent deformation of the contacted overhanging portion of the distal cap, even in the absence of external heating. "Although no external heating is required, in some embodiments it may be necessary Heating equipment and / or thermoplastic backing. In some embodiments, it can be used in a capping step as described by the use of heat and pressure (e.g., the capping steps described in U.S. Patent Nos. 5,077,870 (Melbye et al.) and 5,845,375 (Miller et al.). The method of the invention is applied when the end cap is still warm. 157086 is heated before the distal cap is in contact with the implement or when it comes into contact with the implement. Doc •29· 201208883 In the case of the application, the heating is heated at a temperature lower than the temperature of the distal end cap. Where the thermoplastic material used to form the upstanding member is a copolymer (e.g., a copolymer of ethylene and propylene), the distal cap may have more than one melting temperature in such embodiments, "below the melting of the distal cap" "Temperature" means lower than at least the melting temperatures. For example, the thermoplastic web can be heated in a heating chamber, such as an oven, or it can be treated with ir radiation or hot air. In some embodiments, the structured surface may be in the range of from 40 C to 80 ° C (in some embodiments, from 5 〇〇 c to 6 〇. in the range of 〇 in the implement as a needle) prior to contact with the implement The hot air may be introduced via the needle to heat the implement and/or the structured surface when the distal cap is in contact with the implement. In other implementations, the implement may be a rigid line or a heated gap. In some embodiments The method according to the invention comprises stretching the thermoplastic backing in at least one side. Stretching may be most advantageous after contacting the distal cap with one or more implements. One or more implements are stretched prior to contact, but column pitch variability may increase due to stretching. Stretching a thermoplastic backing with upstanding elements can be used, for example, to reduce the cost of the resulting structured surface that can be a mechanical fastener. H. There is also a potential reduction in performance due to the reduction in the number of upright elements (e.g., hook elements) per unit area. The method of the present invention can, for example, increase the percentage of upright elements that can be engaged with the looped fibers by poetry. And/or Each increase by a: = the tooth holding force to counteract the reduction of the potential effectiveness of the upstanding element density loss in the other, before stretching higher pin density (density of 157,086 upstanding member. Doc 201208883 degrees) The beginning will lead to the density of the erect elements that can be used after stretching. For example, when the erect element is prepared for (10) (3·piece/in2), the density of the upright member stretched to a width of about 2:1 is 55〇^(10)〇/in2), the agreement is 248 per piece of conventional pin density. Tensile and two: again used for mechanical fasteners. The thermoplastic with upright elements provides tensile-induced molecular orientation in the backing. For embodiments of the stretched thermoplastic backing, the web can be biaxially or single drawn by techniques known in the art. In the case where the thermoplastic backing is a web of a length that is not sized, for example, uniaxial stretching in the machine direction can be performed by pushing the thermoplastic web over a roll of increasing speed. The most common stretching method that allows uniaxial stretching, sequential biaxial stretching, and simultaneous biaxial stretching of the plywood network uses a flat film tenter device. The device grasps the thermoplastic mesh using a plurality of clips, clamps or other film edge grip members along opposite edges of the thermoplastic web in such a manner that it is obtained by advancing the grip members at varying speeds along the diverging track. Uniaxial stretching, sequential biaxial stretching, and simultaneous biaxial stretching in a desired direction. Increasing the speed of the clip in the machine direction generally results in stretching in the machine direction. Components such as diverging orbits generally result in stretching in the transverse direction. Uniaxial stretching and biaxial stretching can be accomplished, for example, by the method and apparatus disclosed in U.S. Patent Application Publication No. 2005/0202205 (Petersen et al.), the disclosure of which is incorporated herein. For example, a flat film tenter stretching apparatus is commercially available from Briicknei: Maschinenbau GmbH, Siegsdorf, Germany. In some embodiments, the stretching increases at least one of the length or width of the thermoplastic backing by at least 1. 5 times (in some embodiments, at least 2 times, 2. 5 157086. Doc 31 · 201208883 times or 3 times). In some embodiments, the stretching increases both the length and the width of the thermoplastic backing by at least 丨. 5 times (in some embodiments, at least 2 times, doubles or 3 times). In some embodiments, the stretching increases the length or width of the thermoplastic backing by at least a factor of 10 (up to 7 or 5 times in some embodiments). In some embodiments, the stretching increases both the length and width of the thermoplastic back by up to 10 times (in some embodiments, up to 7 times) and the stretch can be adjusted to impart desired properties (eg, desired Maximize the ringing. In some embodiments, the stretching is performed at least to a natural draw ratio. Uniaxially stretched or biaxially drawn plastic film (eg, 'thermoplastic backing as described herein) at temperatures below the melting point of the thermoplastic material, particularly at temperatures below the film drawing temperature of the film. At the time, the thermoplastic film can be stretched unevenly and form a sharp boundary between the stretched portion and the unstretched portion. This phenomenon is called necking or line drawing. However, when the thermoplastic backing is stretched to a sufficiently high extent, the entire thermoplastic backing of the bead is uniformly stretched. The pull ratio when this happens is called the "natural stretch ratio" or the "natural draw ratio". For example, the apparent draw ratio can be defined as the stretch M ° South in the case where the relative standard deviation of the local stretch ratio is less than about I5% at a plurality of locations on the thermoplastic backing. Stretching at natural draw ratios should be understood to provide significantly more uniform r-buy or properties such as thickness, tensile strength, and modulus of elasticity. For any], ', D疋 thermoplastic backing and stretching conditions' by a number of factors (such as a thermoplastic resin composition forming a thermoplastic backing) (for example) due to J% in the tool roll The form of the thermoplastic backing formed by the quenching conditions, as well as the length of the dish and the draw ratio to determine 157086. Doc -32- 201208883 2 The stretch ratio. In addition, in the case of a biaxially stretched thermoplastic backing, the natural stretch ratio in the - direction will be affected by the stretching conditions, including the final stretching in the other direction, which can be said to be fixed in the - direction. The stretching ratio may exist in the other direction in the natural stretching ratio, or may exist as a ratio of the natural stretching ratio to the stretching ratio (in the first direction - the stretching ratio and the pulling in the second direction) Stretch ratio). The term "stretch ratio" refers to the ratio of the linear dimension of a given portion of a thermoplastic backing after stretching to the linear dimension of the same portion prior to stretching. In some embodiments, stretching is performed at elevated temperatures. This situation may allow the thermoplastic backing to be more flexible for stretching. Heating can be provided, for example, by IR radiation, hot air treatment, or by performing stretching in a heating chamber. In some embodiments, only heat is applied to the first surface of the thermoplastic back (i.e., the surface opposite the surface from which the upright member is protruded) to minimize any damage to the covered stem caused by heating. Chemical. By way of example, in such embodiments, only the roller that is in contact with the second surface of the thermoplastic backing is heated. After stretching, the thickness of the thermoplastic backing is reduced such that the ratio of the thickness of the thermoplastic backing prior to stretching to the thickness of the thermoplastic backing after stretching can be, for example, from 2:1 or 3:1 to 1 〇: 1, in some embodiments, it can be from 5:1 to 10. 1. The thickness of the thermoplastic liner can be, for example, from 5 μm to 200 pm, from 1 μm to 100 μm or from 30 to 1 to 7 μm. After stretching, the final density of the upright members is lower than Initial Density of Upright Elements In some embodiments of the method of making a structured surface according to the present invention, the upright elements have at least 2 //cm2 (i29/in2), 40/cm2 (258 157086.

For example, the final density of the upright elements can be at least 248/cm2 (160 (HSI Μη2) or at least about 394/cm2 (2500/in2). In some embodiments, the final density of the erect elements can be more Up to 787 / cm2 (5 000 / in2) or up to about 1182 / cm2 (7500 / in2).
