Problems solved by technology

One-way conductive fabrics realized by finishing methods such as printing or coating have one-way conductive function, poor washing resistance, hard and dry feeling, which affects the softness and comfort when wearing.
And this process is suitable for flat cloth surface, not suitable for fabrics with fluff or concave-convex structure on the reverse side, and the fabric body is relatively thick, which makes it feel oppressive when worn, and lacks thermal insulation performance; the existing double-sided patented fabric has passed structural design. Combined with the single conduction function realized by the matching of raw materials, for example, the clothing surface adopts mesh structure, while the skin-adhering surface adopts plain weave and other structures. Since the plain weave structure has less gaps, it is not conducive to the contact and diffusion of sweat to the absorbent material on the clothing surface
The existing processing methods for unidirectional moisture-conducting fabrics have disadvantages such as narrow range of suitable fabrics, high production and processing costs, and unsatisfactory unidirectional moisture-conducting effects, and the existing methods have not studied the influence of the structure of the processed fabrics and the unidirectional moisture-conducting effect

Embodiment 1

[0043] first yarn Y 1 Using mechanical elastic polyester 75D / 48F, the second yarn Y 2 Polyester 40D / 72F is used, among which, the first yarn Y 1 diameter D 1 with the second yarn Y 2 diameter D 2 Ratio ≥ 1.2, the first yarn Y 1 Water conductivity of LP 1 with the second yarn Y 2 Water conductivity of LP 2 Ratio1 and n of the second yarn Y 2 A unit loop structure woven into the fabric body is arranged in an adjacent or alternate manner, m=1, n=1 in Example 1; and the first yarn Y 1 or the second yarn Y 2 Any one of the yarns is distributed in a ratio of 1:1 on the clothing side 1 and the skin-fitting side 2 of the fabric body.

[0044] In this example, a plane made of the yarn was formed by tightly winding the yarn on a microscope slide, water was dropped on the plane by a contact angle measuring instrument, and the contact angle θ thereof was measured. first yarn Y 1 (model is round PES 75D / 48F) contact angle θ 1 is 63°, the second yarn Y 2 (model is round PES 40...

Embodiment 2

[0074] On the basis of Example 1, the converted material is used to weave a polyester and nylon knitted fabric with a double-sided structure.

[0075] Use ordinary round polyester 75D / 36F as the first yarn Y 1 and Nylon 66 (50D / 48F) as the second yarn Y 2 . The two yarns are interlaced to form the main body of the fabric, which is then piled. M the first yarn Y 1 and n of the second yarn Y 2 A unit loop structure woven into the fabric body is arranged in an adjacent or alternate manner, m=1, n=1 in Example 1; and the first yarn Y 1 or the second yarn Y 2 Any one of the yarns is distributed in a ratio of 1:1 on the clothing side 1 and the skin-fitting side 2 of the fabric body.

Embodiment 3

[0096] On the basis of embodiment 1, adopt the first yarn Y 1 : Ordinary round polyester 75D / 36F and second yarn Y 2 : Cross-section nylon yarn 70D / 68F, the two yarns are interwoven to form the fabric body, and form a weft-knitted double-sided fabric.

[0097] first yarn Y 1 (75D / 36F) Polyester monofilament equivalent radius is:

[0098]

[0099] D. Y1 =2×7.36=14.72(μm)

Abstract

The invention discloses a double-face basic structure differential moisture-conducting fabric. The fabric comprises a fabric body; the fabric body is a weft-knitted fabric which is formed by interweaving first yarns and second yarns and provided with a garment face and a skin-attaching face; the first yarns include at least one yarn, and the second yarns include at least one yarn; the diameter of the first yarns is larger than that of the second yarns; the fabric body is provided with a plurality of unit circulation weaves formed by weaving the first yarns and the second yarns in an adjacent or alternate arrangement mode; and in one unit circulation weave, the length distribution ratio of any one of the first yarns or the second yarns on the garment face and the skin-attaching face is 1: 1, so that the garment face and the skin-attaching face have the same basic structure, and the two-face differential moisture-conducting capability of liquid water transferred from the skin-attaching face of the fabric body to the garment face is greater than or equal to 100%. The fabric is uniform and stable in one-way moisture-conducting capacity, dry, comfortable and non-sticky to wear, and suitable for making T-shirts, trousers, shirts and the like.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a differentiated moisture-conducting fabric with a double-sided basic structure. Background technique [0002] One-way conduction phenomena widely exist in nature, such as plant nerve conduction, water and energy transmission, etc. Through the bionic design, one-way conduction effectively solves many practical problems such as oil-water separation and mist capture in the process of separation or collection. In recent years, people have put forward higher requirements for the comfort and functionality of clothing, and multi-functional textiles such as waterproof and moisture-permeable, moisture-absorbing and quick-drying, heat-conducting and cool-feeling have received extensive attention. [0003] At present, there are two main methods of producing unidirectional moisture-wicking fabrics in the industry: one is to use coating or printing technology to print water-repellen...
