Example 1

As shown in fig. 1, a breathable elastic three-dimensional woven fabric, a plurality of wefts a are woven in warps a at equal intervals, warps b are woven in odd-numbered wefts a, and the joints of the warps a, the warps b and the wefts a are interwoven with each other; the warp c is woven in the even number of the weft a, and the junctions of the warp a, the warp c and the weft a are interwoven with each other. Wherein the warp a is 200D terylene elastic monofilament, the cross section of the terylene elastic monofilament is flat and long, and in some examples, the cross section of the terylene elastic monofilament is a runway type. The weft a is polyester low-melt yarn of 14.8 multiplied by 2tex plied yarn, the polyester low-melt yarn is blended yarn of low-melt polyester and common polyester, the blending ratio is 50% of the low-melt polyester and 50% of the common polyester.

the method comprises the following steps: designing a fabric weave structure;

step six: heating the multi-layer fabric by a heat setting machine to form the breathable elastic three-dimensional woven fabric of any one of claims 1 to 9.

The first to fifth steps are to make the warp a1, the weft a2, the warp b3, the warp c4, the weft b5 and the weft c6 into a flat fabric. And step six, carrying out heat treatment on the plain weave fabric, wherein the heat treatment is divided into two parts, one part is a thermal bonding process of the polyester low-melt yarns, and the other part is a thermal shrinkage process of the high-shrinkage polyester yarns. The thermal bonding and the thermal shrinkage are both prepared by adopting a hot air method, the conveying speed of the flat fabric in a hot air method drying oven is 18 meters per minute, the average heating time of the flat fabric in the drying oven is 90 seconds, when the temperature for heating the flat fabric by the drying oven reaches 90 ℃, the high-shrinkage polyester yarns begin to shrink, the polyester elastic monofilaments slightly bend, at the temperature of 110 ℃, the polyester low-melting yarns melt and are bonded with the high-shrinkage polyester yarns and the polyester elastic monofilaments, and the bonded polyester low-melting yarns serve as anchor points to fix the polyester elastic monofilaments between the single-group polyester low-melting yarns and the single-group polyester low-melting yarns, so that the polyester elastic monofilaments are prevented from transversely deviating under the self-rigidity effect. The shrinkage rate of the high-shrinkage polyester yarns is 40% -50%, after the high-shrinkage polyester yarns are treated by the oven, the high-shrinkage polyester yarns shrink to enable the polyester elastic monofilaments to be subjected to wave crest-shaped bending, and a wave crest-shaped cavity is formed between the polyester elastic monofilaments and the high-shrinkage polyester yarns to form a three-dimensional woven fabric.

When the elastic monofilament of the polyester is selected to be smaller than 200D, the rigidity of the polyester yarn is too small, so that the flat fabric with the curved surface is too soft, and the elasticity of the three-dimensional woven fabric is not strong. When the elastic polyester monofilament is selected to be the monofilament larger than 1000D, the elastic polyester monofilament has too high rigidity, so that the shrinkage of the high-shrinkage polyester yarn can be limited, and the surface bending amplitude is small, so that the three-dimensional woven fabric has no elasticity.

Example 2

In this embodiment, two warps a1 and three wefts a2 are selected, and two warps a1 are interwoven with each other, that is, a single warp a1 is woven in an up-and-down circulation manner, a down line of one warp a1 and an up line of another warp a1 form an interweaving point, and the interweaving point is a weaving point of a single group of wefts a3 and is also a weaving point of a warp c 4. On a single warp a1, warps b3 are woven between odd groups of wefts a2, and warps c4 are woven between even groups of wefts a2, so that the upper and lower surface layers of the three-dimensional woven fabric further adopt the warps b3 as the warps. In some examples, the upper and lower surface layers of the three-dimensional woven fabric further use warp c4 as warp.

the method comprises the following steps: selecting 600D polyester elastic monofilament and 200D high-shrinkage polyester yarn as warp yarns, and 18.5 multiplied by 2tex polyester low-melt yarn, 200D polyester monofilament and 900D polyester multifilament as weft yarns;

step two: warping the elastic terylene monofilament by a sectional warping machine to form a beam I, wherein the number of the warp is 8118; warping the terylene high-shrinkage fiber to form a beam II, wherein the warping number is 8118 binding yarns and 8 multiplied by 2;

step three: performing drafting yarn inserting and reed inserting on the terylene elastic monofilament of the beam I and the terylene high-shrinkage fiber of the beam II through a drawing-in machine, and processing into a penetrated beam;

step four: and weaving on a loom, namely weaving a multi-layer fabric by using a biaxial dobby rapier loom with warp yarns of the polyester elastic monofilaments threaded through the loom beam I and the polyester high-shrinkage fibers threaded through the loom beam II and weft yarns of the polyester low-melt yarns, the polyester monofilaments and the spun yarns. Arrangement ratio of two kinds of warp yarns: the terylene stretch monofilament/terylene high-shrinkage fiber is 3/1, and the weft insertion cycle of three weft yarns is as follows: 1 weft of staple fiber yarn, 2 wefts of polyester monofilament, 2 wefts of staple fiber yarn, 2 wefts of polyester monofilament, 1 weft of staple fiber yarn, 1 weft of polyester low-melt yarn, 1 weft of staple fiber yarn, 1 weft of polyester low-melt yarn and 1 weft of staple fiber yarn; the weft density on the machine is 346 pieces/10 cm.

Step five: the multilayer fabric is heated by a heat setting machine, the heating temperature is 150-170 ℃, and the length of the fabric is shortened due to the thermal shrinkage of the polyester high-shrinkage fibers, so that the upper layer fabric, the middle layer fabric and the lower layer fabric which are formed by polyester monofilaments form waves, and the breathable elastic three-dimensional woven fabric is realized. Meanwhile, after the terylene low-melting yarns are heated (above the melting point), the terylene low-melting yarns are dissolved and regularly dissociated on the surface of the warp yarns, and after the temperature is cooled, the terylene low-melting yarns are solidified again and adhered on the surface of the warp yarns, the warp and weft tissue points of the fabric are adhered and adhered by the terylene low-melting yarns at the moment, so that the fixing, contacting and positioning effects are effectively realized, the warp yarns and the weft yarns are mutually adhered and dragged, the terylene monofilaments between each other are effectively restrained from displacement accumulation or slippage and evacuation phenomena under the action of external force, and therefore the stable breathable elastic three-dimensional woven fabric is formed.
