One-way moisture-conducting weft-knitting and warp-knitting-imitating small-grid elastic fabric and preparation method thereof

Abstract

The invention discloses a one-way moisture-conducting weft-knitting and warp-knitting-imitating small-grid elastic fabric and a preparation method thereof. According to the fabric, a conventional rib air layer weave and a stitch single-face looping system are additionally arranged as a weave, specifically, the fabric weave is woven into a complete weave through four looping systems, knitting of the first path is that upper needle floating threads and lower needle looping form a row of front plain stitches, knitting of the second path is that upper needle looping and lower needle floating threads form a row of back plain stitches, the knitting of the third path is that upper needle floating threads and lower needle looping form a row of front plain stitches, and the knitting of the fourth path is that upper needle looping and lower needle looping form 1 + 1 rib stitches; and the threading mode of the fabric is as follows: the first path is 1A, the second path is 1C, the third path is 1A, the fourth path is 1BC, and the yarn counts of the cotton yarns of the first path and the third path are thicker than the plaiting yarn counts of the terylene / spandex of the fourth path. The fabric provided by the invention simultaneously meets the requirements of one-way moisture conduction function, check pattern effect, good transverse stability, light weight, comfort and the like, and is extremely good in environmental protection property.

Description

technical field [0001] The invention belongs to the field of weft-knitted unidirectional moisture-guiding fabric and its production technology, and in particular relates to a weft-knitting imitation warp-knitted small grid elastic fabric and a preparation method thereof. Background technique [0002] In recent years, the application of unidirectional moisture-wicking properties to textile fabrics to keep human skin dry has been favored by consumers. The unidirectional moisture transfer of the fabric comes from the difference in the moisture absorption properties of the inner and outer layers. Under the action of the differential capillary effect, human sweat is transferred from the hydrophobic surface of the inner layer to the hydrophilic surface of the outer layer without backflow. The unidirectional moisture permeability of the fabric can be realized through various processing methods such as chemical method, plasma modification method and structural design method. The sil...

AI Technical Summary

Problems solved by technology

[0003] In terms of fabric structure, the main mechanism based on unidirectional moisture transfer is the differential capillary effect, so at present, some unidirectional moisture transfer fabrics are designed with double or triple layers. The two-layer structure is mainly based on the moisture-conducting layer and the moisture-absorbing layer. The three-layer structure adds a layer of conductive layer between the moisture-conducting layer and the moisture-absorbing layer to improve the effect of one-way moisture-conducting, but at the same time it also makes the fabric Increased thickness and poor air permeability limit the use of the fabric as a summer fabric

[0004]Existing unidirectional moisture-wicking fabrics are obtained after finishing with chemical reagents or through multi-layer structure design. The fabric obtained by the structural design is thick and poor in air permeability, and the application range is limited

Conventional weft-knitted fabrics have good ductility, but poor shape retention
