Abstract
The invention relates to the field of textile, in particular to a braiding method for enlarging the spacing between two layers of double-layered laminated fabrics. The braiding method comprises the following steps: interweaving upper-layer warps (2) with common wefts (1) into an upper-layer fabric; interweaving lower-layer warps with lower-layer common wefts (1) into a lower-layer fabric; furtheradding a group of soluble wefts to the common wefts (1) of the upper-layer fabric and the lower-layer fabric, wherein, the soluble wefts are not interwoven with the upper-layer fabric and the lower-layer fabric; interweaving a third group of yarn pile warps (4) with the upper- and lower-layer common wefts (1) or the soluble wefts (3) alternately between the upper-layer fabric and the lower-layer fabric, so that the upper-layer fabric and the lower-layer fabric can be connected together, wherein, the soluble wefts (3) are knoted with a handful of warps (2) in heavy weft form; dissolving the soluble wefts (3) therein in water at a certain temperature after the fabrics are interwoven; and straightening the pile warps (4), so that the spacing between the upper-layer fabric and the lower-layerfabric can be expanded. The invention can greatly expand the spacing between the upper-layer fabric and the lower-layer fabric and achieve continuous production without modifying the existing processing equipment.
Description
(1) technical field
The present invention relates to the material knitting skill of field of textiles, particularly relate to a kind of braid method that improves braiding two layers of double-layered laminated fabrics two interlamellar spacings.
(2) background technology
Utilize textiles to be called textile structural composite materials as the reinforcing material formed composite that combines with matrix.
Fabrics such as picture plush, double-deck velvet carpet in textiles for general use, weaving on special loom, the state that fabric is made into before the clipping of back is exactly that double-deck layer links the structure fabric, as Fig. 1, shown in Figure 4.Usually adopt two rapier weft inserting looms, utilize double-deck through the weaving of fluffing hatching.Be that top line and upper layer weft yarns are woven into upper layer of fabric, lower layer warp yarns and lower floor's weft yarn are woven into layer fabric, two-layer fabrics keeps at a certain distance away, alternately interweave by the 3rd group of yarn (suede warp) with upper and lower layer weft yarn, upper and lower two-layer fabrics is combined, distance between the two-layer fabrics equals two-layer height of naps sum, the fabric that is made into is through the clipping operation, after the suede that connects two layers of base fabric therefrom severed via reciprocal cutter, just can obtain the two-layer velludo that has vertical fine hair respectively.
In fabrics for industrial use, utilize various fibers to make the textile structural composite materials of described two layers of double-layered laminated fabrics, central authorities inflate, and extensively apply to the aspects such as interlayer, hull material, baby plane fuselage, box thermal car, blade core, interval insulant and floor of storage tank.Advantages such as that these materials have is high-strength, withstand voltage, wear-resistant, heat insulation, shock resistance and break resistance are good, therefore can satisfy most of fillings, at interval, the requirement of heat insulation and bearing structure material.
The weaving method of existing processing double-layer fabrics, can not disposablely be woven into higher thickness, bilevel spacing (or thickness) is with last, the sendout of vertical range and suede warp is relevant between lower floor's ground warp harness eye, these adjustable ranges are limited on existing loom, on general, following interlamellar spacing is no more than 30mm, but, the bigger two layers of double-layered laminated fabrics of market some thickness of some product needed, bilevel spacing wishes to surpass 30mm, inflation lifting pad such as disaster relief occasion, air bags etc. when reaching two bigger interlamellar spacings, wherein just can charge into more gas, play stronger gas pressure, take on the effect of lifting pad.
(3) summary of the invention
The objective of the invention is to intend providing a kind of equipment that utilizes existing production and processing two layers of double-layered laminated fabrics, can produce a kind of braiding processing method that spacing between two layers of double-layered laminated fabrics is enlarged.
Purpose of the present invention is solved by following technical scheme:
A kind of braid method that enlarges spacing between two layers of double-layered laminated fabrics, top line and upper strata normal weft are woven into upper layer of fabric, lower layer warp yarns and lower floor's normal weft are woven into layer fabric, it is characterized in that, in the weft yarn of levels fabric except that normal weft is arranged, also increase by one group of solubility weft yarn, the solubility weft yarn does not participate in forming interweaving of levels fabric.Between two-layer fabrics by the 3rd group of yarn suede through alternately interweaving with upper and lower layer normal weft or solubility weft yarn, upper and lower two-layer fabrics is linked together, wherein the solubility weft yarn carries out access node with form and a spot of warp thread of heavy latitude, after fabric is made into, water-soluble solubility weft yarn wherein by uniform temperature, stretching suede warp, the two-layer fabrics spacing is increased lengthening up and down.
Described solubility weft yarn is a soluble polyvinylalcohol.
Described heavy latitude is a normal weft and can overlaps with a kind of institutional framework form by a dissolubility weft yarn.
Described a spot of warp thread is meant the warp thread of 10-20%.
Adopt the technical program, do not need existing equipment is transformed, when Dobby Weave Design, except that normal weft is arranged, also increase by one group of water-soluble weft yarn in the weft yarn of levels fabric, the solubility weft yarn does not participate in forming interweaving of levels fabric backing.Be that top line and upper strata normal weft are woven into upper layer of fabric, lower layer warp yarns and lower floor's normal weft are woven into layer fabric.Two-layer fabrics keeps at a certain distance away, alternately interweave by the 3rd group of yarn (suede warp) with upper and lower layer normal weft or solubility weft yarn, upper and lower two-layer fabrics is linked together, in the arrangement process after fabric is made into, the water-soluble solubility weft yarn that goes by uniform temperature, bilevel spacing is opened, and the spacing that the spacing of this moment is set when weaving on the previous machine has realized purpose of the present invention.
The ground tissue of levels fabric adopts plain weave or heavy flat fabric tissue, can design through space density, height suede, changes to realize upper and lower interlamellar spacing (thickness), to satisfy the needs of different application environment.
The present invention can be used as composite material reinforcement body, and the material after compound can be processed into inflation lifting pad, air bag of particular job occasion, disaster relief occasion etc.
Beneficial effect of the present invention:
1. to existing spacing between two layers of double-layered laminated fabrics (thickness) finiteness problem, provide a kind of particular design ways and means, the upper and lower basal spacing of fabric (thickness) is increased greatly, can surpass 30mm, reach 50mm-80mm;
2. the structure of suede through space density, double altitudes or not equal altitude designed, can realize that upper and lower basal spacing (thickness) changes, to satisfy the needs of different application environment;
3. do not need existing process equipment is transformed, just can realize continuous production.
