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...

Examples

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.

[0076] In this embodiment, the known polyester density in the industry is 1360000g / m 3 , nylon density is 1150000g / m 3 . first yarn Y 1 (75D / 36F) Polyester monofilament equivalent radius is:

[0077]

[0078] D. Y1 =2×7.36=14.72(μm)

[0079] Capillary equivalent radius r Y1 =0.227R Y1...

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)

[0100] Capillary equivalent radius r Y1 =0.227R Y1 =1.67(μm)

[0101] It is convenient to calculate the total capillary volume of round 75D / 36F polyester single yarn

[0102]

[0103] Similarly, we calculate the second yarn Y 2 (70D / 68F) The equivalent radius of cross-section nylon monofilament is:

[0104]

[0105] D. Y2 =2×5.48=10.96(μm)

[0106] Capillary equivalent radius r Y2 =0.471R Y2 =2.58μm)

[0107] It is convenient to calculate the total capillary volume of cross-section 70D / 68F nylon single yarn

[0108]
