Abstract

The utility model relates to warp direction framework composite non-woven fabrics, wherein, framework materials are added to warp direction on one non-woven fabric or between two non-woven fabrics. The utility model which enlarges non-woven application field has the characteristics of high strength of the warp direction, tear resistance of the weft direction, high perforation resistance, and low cost. The warp direction framework composite non-woven fabrics can be used for a rubber conveyor belt, a warp direction high-strength geotextile, a water-proof linoleum base fabric, a tarpaulin, etc.

Description

Warp-wise skeleton composite non-weaving cloth

The utility model warp-wise skeleton composite non-weaving cloth is to make with serialization production that the skeleton yarn of warp-wise is compound incessantly goes in traditional non-weaving cloth, produces a kind of new high-strength composite non-weaving cloth of warp-wise, belongs to the textile weaving field.

The production of modern non-weaving cloth is divided into two big classes by raw material mix.First staple fibre method, it two is spun-bond processes.Its structure of the product of said method production all reflects the random mixed and disorderly arrangement of long and short fiber on the cross section of product, the mutual obvolvent of fiber, formation have the geometric shape of certain length and width, thickness and non-group of woven cloths of certain physicochemical characteristics.The normal thin non-weaving cloth is used for adhesive lining, medical and health use cloth, electric insulation cloth, WALL CLOTH, agricultural fabric, cement packing cloth etc.Normal thick type non-weaving cloth is used for geotextiles, gum sprayed cotton, needle punched carpet synthetic leather, filtering material, roof flashing material etc.Because common non-weaving cloth does not have framework material, therefore its tensile strength is not high, can not satisfy the application in some field in the modern industry production, for example: (line) cloth etc. at the bottom of the support frame of tire, conveyer belt, V-belt, rotary hose, rubber hose, petroleum pipeline, water inlet pipe and water outlet pipe.

The non-weaving cloth with framework material of developed countries production at present is longitude and latitude mesh skeleton, complex manufacturing, the cost height, and the market competitiveness is poor, is difficult for applying.At home in the patent of the disclosed application number 92109058.7. applyings date 920731 title on January 27th, 1993 " Nonwovens and manufacture method thereof and manufacturing equipment ", the mode that adds warp thread on non-weaving cloth is actually and is difficult to realize, and because the speed height of lapping, the product of being produced is sheltered a little many, of poor quality.

The purpose of this utility model is the defective that overcomes prior art for the Application Areas that enlarges nonwoven fabric, satisfy the needs in some field in the modern industry production, adopt the needling process of traditional woven cloth warping technology and modern non-weaving cloth and make its a kind of advanced person's who combines practical production method, produce a kind of new warp-wise skeleton composite non-weaving cloth, its cost is low, quality is high, be a kind of new product with property, filled up the domestic blank that has the framework material production during the State's Ninth Five-Year Plan period.

The technical scheme that the utility model adopted is to produce on the basis of non-weaving cloth in the staple fibre method, warp-wise is added with framework material or is added with framework material at the middle warp-wise of two non-weaving cloths in the above, the raw material of non-weaving cloth adopts terylene short fiber, polypropylene chopped fiber, cotton and hair etc., through the perverse one-tenth net of pin.The material of skeleton adopts industrial filaments such as high-strength polyester, polypropylene fibre.

Description of drawings: Fig. 1, add warp-wise skeleton composite non-weaving cloth above being.Fig. 2, add warp-wise skeleton composite non-weaving cloth for the centre.Fig. 3, add warp-wise skeleton composite non-weaving cloth flow sheet above being.Fig. 4, add warp-wise skeleton composite non-weaving cloth flow sheet for the centre.

Wherein 1 non-weaving cloth, 2 framework materials, 3 non-weaving cloths, 4 fibre webs, 5 lapping curtains, 6 give pin speed machine, 7 skeleton warp shafts, 8 reed, 9 warp thread deflector rolls, 10 first road master's needing machines, 11 second road main body thorn machines, 12 warp-wise skeleton composite non-weaving cloths, 13 non-weaving cloth deflector rolls, 14 non-woven yardage rolls.

In conjunction with the accompanying drawings example of the present utility model is further described: the technological process of warp-wise skeleton composite non-weaving cloth is that fibre web (4) process on lapping curtain (5) is given pin speed machine (6), framework material (2) is by skeleton warp shaft (7), reed (8) and warp thread deflector roll (9), be laid on through giving on the fibre web (4) of needing machine (6), promptly produce the product of warp-wise skeleton composite non-weaving cloth (12) again through first road master's needing machine (10) and second road master's needing machine (11).This is the product that warp-wise on non-weaving cloth (1) is added with framework material (2).Laying the compound more afterwards non-weaving cloth (3) of going up of framework material (2) if be added with non-weaving cloth deflector roll (13) and non-woven yardage roll (14) on the later process of warp thread deflector roll (9), its finished product is added with the compound woven cloths of warp-wise framework material exactly between two non-weaving cloths.

Fibre web is through giving needing machine (6) afterwards, carried out preliminary bonding, the brute force of the brute force of warp-wise framework material and fibre web is also comparatively approaching for this reason, framework material and fibre web are easy to obvolvent, add the warp-wise framework material and created good condition because lapping speed is controlled at 5-10 rice/be divided into, composite effect is better.

The malthoid base cloth that on non-weaving cloth, adds warp-wise skeleton composite non-weaving cloth.As with polyester staple fiber 3D * 76mm specification, produce 140g/m ²Fibre web adds 20g/m ²The terylene industrial filament is produced 160/m ²Composite web soaks 40g/m again ²Acrylic latex can bear 200g/m ²The malthoid base cloth.

In the middle of two non-weaving cloths, add the resume a session rubber of non-weaving cloth of warp-wise skeleton and transmit base cloth.As with 60%3D * 76mm terylene, produce 300g/m with 40% cotton fiber mixing lapping ²Fibre web adds 500D industry polyester filament 100g/m in the middle of two-layer fibre web ², produce 700g/m ²Composite web is soaked 100g/m again ²Benzene pyrrole latex.Its product performance index is equivalent to 104 ^#Every index of canvas, cost can reduce by 20%.

Make the powerful increase of warp-wise owing to add framework material, by the powerful original product of adjusting 1: 1, the broadwise brute force can be increased to 150N/5cm by 100N/5cm.

Advantage of the present utility model and good effect be the application that enlarged non-weaving cloth can be used for Rubber Conveyor Belt Scrap, Tar felt base cloth and tarpaulin etc. have satisfied modern industry to produce the needs in some field, have filled up the framework material product The blank that product are produced, this product have the powerful height of warp-wise, broadwise tear-proof, wearing out property of high resistance, low cost and other advantages Bigger promotional value is arranged, and good economic and social benefit.
