Description

1220106 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a waterproof zipper and a manufacturing method thereof, particularly a nylon zipper coated with a high adhesive agent on a back layer to combine a Pu film, and a manufacturing method thereof. [Prior art] Among the various waterproof zipper manufacturing methods known in item 4, there is a treatment method of soaking a water repellent agent on the zipper tape, which is generally called a water repellent treatment method. The effect cannot be long-lasting, and it is not heat-resistant, and the waterproof effect will be minimal when it encounters a lot of rain.

Other waterproof zippers, such as “Non-air-tight Zipper Tooth Straps” No. 0 94285 published in China on December 16, 1987, are Japanese and Japanese valuable precious shares Co., Ltd. , Referred to as γ κ p company), although the case has an impervious layer covering the cloth tape, it must be wrapped around each sprocket (5) with [2 clamping strips (7) in an embedded form. == Si) The back-folded edge portion of the base fabric (8), and the water-impermeable layer and 4: = ,,, σ a The elastic rubber material (9) is heated and then fixed to the base fabric (8) ) On the title, the Ϊ Ϊ method will be peeled off due to elastic fatigue after long-term use, and the skin owners such as the domestic 1 January 990} Announcement No. 1 2635 1

Description of the invention (2) Secondly, there is also the patent case of “Glass Impervious to Fluid” published in Domestic Announcement No. 5037715 on September 21, 2002, which is also a Japanese commercial and valuable company. The application requires that this zipper must be matched with a special zipper head, and cannot be used with a general zipper head, so the scope of application is limited and the popularity is not good. In addition, for example, US Patent Publication No. 6, 105, 214, August 22, 2000, rWater Resistant Slide Fastener and Process For PreParing Same "Inventor: Stuart press, the feature of this waterproof zipper is the tape The second layer is provided with a waterproof layer. The adhesion of the waterproof layer is more than six pounds per inch, and the helmet is still perforated when the abrasion resistance test is more than two hundred revolutions. The waterproof layer can be a multilayer film and the Clark strength displayed by the zipper Not more than 30 cm (Clark stiffness of less than 〇r called mouth "to about 30cm); the only solution is to apply glue to the surface of the waterproof film, and then adhere the waterproof film to the cloth tape, so the waterproof film is The glue can be fixed on the tape, but the glue cannot completely penetrate into the tape, so it is adhered by coating method. Once the waterproof film is cut or damaged by external force, it is difficult to achieve the anti-seepage effect. In addition, The article discussed the use of multi-layer film to achieve the anti-seepage effect, which is transferred on the cloth tape with a low hardness film as the inner film, and then transferred the outer film with high hardness on the inner film to make it a composite film, but Disadvantage is thick Increasing the hardness increases the softness of the zipper, and the inner membrane does not penetrate into the fabric fibers thoroughly, so there is room for firmness and impermeability. In addition, US Patent Publication No. 6 of August 6, 2002 , 427 294 "Waterproof Slide Fastener and Manufacturing Method Thereof" Applicant ·· Japanese Commercial Co., Ltd. (γκκ Corporation); The waterproof layer of this waterproof zipper is a multilayer composite film, changing the old 1220106 V. Description of the invention (3) The 'waterproof film' is a combination of a high-temperature melting layer and a low-temperature melting layer; its high-temperature melting layer is outside and has a waterproof effect, and the low-temperature melting layer is attached to the zipper tape fiber. The disadvantage is that the production cost of the multilayer composite film is relatively high and the unit price is relatively high, which is disadvantageous from a consumer standpoint. In addition, it is also implemented by using hot-melt adhesives or ultrasonics, that is, the waterproof film is directly attached to the zipper tape to achieve the purpose of waterproofing. However, this waterproof zipper method is not resistant to high temperature, and it is not resistant to long-term immersion in organic solvents for dry cleaning of clothing. [Invention I. The desired layer of the hair layer film suffers from the disadvantages of time-consuming labor and zipper intolerance, and the high content of the zipper tape of the hair layer, and the screen printing technology of this hair prints, but it is not subject to external appearance] Zhiming's main damage cost increases

Technical problems are easy to add after the purpose, or use it without further improvement. The pull-up layer is reprinted on the screen after heating, so it rubs a chain cloth belt in the world, and then plasticizes the water-repellent layer for the purpose. It is to solve the problem that conventional waterproof zippers infiltrate due to the formation of a single liquid, or that multi-layer film processing and manufacturing costs require the use of a specific slider; and that general waterproofing can be durable, resistant to hydrolysis and solvent impregnation, and provides a high adhesion The layer combines the waterproof and the waterproof layer, and a layer can penetrate into the cloth height, and the waterproof layer and the waterproof layer are mainly combined with PU to form a stronger waterproof layer. It can be the same on the inner surface of the waterproof layer of the waterproof zipper, and the floating water can be embossed on the inner surface of the waterproof layer. After molding, the pattern hidden in the waterproof layer is not more clearly identifiable, and there is no pattern loss.

Explanation of the invention (4) Problem arises—solve to solve the problem of good shoot 1 chain through the back, this (pu condensation polyester fiber is fully volatile; the roller pressure is processed by the heating box u film and P slit processing to The technical means of infiltrating the zipper problem according to the left and right prefaces: A method for manufacturing a waterproof zipper to solve the problems of the aforementioned waterproof zipper; j glue device, the main component of the high adhesive agent is the second glue. After heating and drying treatment, the paper is then pasted onto the release paper and then pasted onto the coated p U. The heating gel at 120 t ~ 200 ° C is used to fully plasticize the U gel to form a cutter and form a waterproof layer. Cut in the center, the two tapes are separated, and can be added to the pressurized tape tape after the zipper step. The present invention at least uniformly coats the liquid heat rack, applies the coating of another gel on the PU, and presses the waterproof layer to separate the head. The use of the head includes the following steps: one can penetrate after the nylon bridge type polyurethane A PU pull-button cloth tape in the gel is squeezed, and finally, the left and right X3X3 are made of a long-lasting I chain cloth ester tree. The cloth tape is $ solvent%. The film is penetrated; the month makes P cut. Waterproof layer

The layer of the waterproof layer will show that the ink has a stitching σ co-operative street film produced by the two right sides with stitching. The layer is ® according to the previous claim. The protruding direction is set to be used on the cloth, and then to the cloth with a thermoplastic fiber wool net version: brush-type in the plastic waterproof layer ± production samples, symbols or text. Said waterproof zipper manufactured by the manufacturing method, the bean cloth tape 'two cloths with front and back sides, in front; inner: thread, and the nylon sprocket is looped around the periphery of the cable, more on the car ^, a row Nylon sprocket has a waterproof layer on the back side of the two cloth tapes under the action of the zipper. It is characterized in that the back side penetrates into the Pu gel, and the Pu gel is combined with ρ υ to form a waterproof layer. This waterproof layer includes infiltration. The upper layer inside the pores of the tape and the lower layer outside the tape.

3. Contrast the effect of the prior art: The following advantages can be obtained by the implementation of the present invention: 1. The p U gel in the waterproof layer is penetrated into the fabric of the tape fiber, so it has the function of blocking water and seepage. Therefore, even after the outer PU film is damaged by external force, the zipper tape still has the infiltration of the inner p U gel to prevent water from invading, so that the tape will not be wet. This can overcome the tendency of the conventional single-layer waterproof film to be damaged after being damaged. Causes the disadvantage of liquid penetration. 2 · P U gel and p U film are combined into a single-layer film by thermoplasticization, which will not cause the same increase in hardness as conventional multi-layer composite films due to being too thick, and it will not be easy to manufacture and will take time and labor. 3 · Single-layer waterproof layer is easier to manufacture than traditional style, and the cost can be reduced;
