A polyester cotton double-layer fabric

Abstract

A polyester-cotton double-layer fabric includes an outer layer and an inner layer connected by bonding warp yarns. The outer layer is a 2-up, 2-down right-hand twill weave composed of outer layer warp and weft yarns. The inner layer is a 1-up, 3-down right-hand twill weave composed of inner layer warp and weft yarns. The outer layer warp and bonding warp yarns are polyester filaments; the outer layer weft yarns are abrasion-resistant yarns; the inner layer warp yarns are cotton fiber yarns; and the inner layer weft yarns are moisture-wicking yarns. Based on this new polyester-cotton double-layer fabric, the outer layer warp yarns are made of polyester filaments, combined with the abrasion-resistant yarns of the outer layer weft yarns, effectively resisting external friction and improving the overall durability of the fabric. The inner layer warp yarns are made of cotton fiber yarns, retaining the soft, close-fitting, moisture-wicking, and breathable properties of cotton fibers, making the fabric more comfortable when in contact with the skin, reducing stuffiness during wear, and improving the skin-friendly experience of daily wear. Combined with the moisture-wicking yarns of the inner layer weft yarns, it facilitates the wicking away of sweat from the skin, enhancing the dryness of the garment.

Description

Technical Field

[0001] This utility model relates to a polyester-cotton double-layer fabric, belonging to the field of textile fabric technology. Background Technology

[0002] With the improvement of people's living standards and the diversification of lifestyles, the functional requirements for clothing are also increasing. For example, sportswear needs fabrics with good moisture-wicking properties and abrasion resistance. Polyester has advantages such as high strength, good abrasion resistance, and strong wrinkle resistance, but its moisture absorption and breathability are relatively poor; cotton fiber has the characteristics of being soft and close-fitting, moisture-wicking and breathable, but it is prone to wrinkling and has relatively weak abrasion resistance. In order to combine the advantages of both, this application provides a polyester-cotton double-layer fabric. Utility Model Content

[0003] The purpose of this invention is to provide a polyester-cotton double-layer fabric that combines the advantages of both polyester and cotton fibers, resulting in a fabric with good moisture absorption and wicking properties as well as abrasion resistance.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] Example 1 Combination Figure 1-2 This embodiment provides a detailed description of a polyester-cotton double-layer fabric, comprising: an outer layer 1 and an inner layer 2, wherein the outer layer 1 and the inner layer 2 are connected by a bonding warp yarn 13; the outer layer 1 is a two-up, two-down right-hand twill weave formed by outer layer warp yarns 11 and outer layer weft yarns 12; the inner layer 2 is a one-up, three-down right-hand twill weave formed by inner layer warp yarns 21 and inner layer weft yarns 22; the outer layer warp yarns 11 and bonding warp yarns 13 are polyester filaments; the outer layer weft yarns 12 are abrasion-resistant yarns; the inner layer warp yarns 21 are cotton fiber yarns; and the inner layer weft yarns 22 are moisture-wicking yarns.

[0013] Polyester has advantages such as high strength, good abrasion resistance, and strong wrinkle resistance; cotton fiber has the characteristics of being soft and close-fitting, moisture-wicking and breathable.

[0014] Furthermore, the warp yarns are arranged in the following order: one outer warp yarn 11, one inner warp yarn 21, and one splicing warp yarn 13; the weft yarns are arranged in the following order: one outer weft yarn 12 and one inner weft yarn 22.

[0015] The outer layer 1 and inner layer 2 are connected by a bonding warp 13 to form a bonded double-layer structure. The bonding warp 13 interweaves with the outer and inner weft yarns in one weave cycle, connecting the two layers together. The bonding warp 13 is bonded above the outer weft and below the inner weft. Since the bonding points are not exposed on the front and back of the fabric, the bonding points are arranged as follows: the bonding point of the bonding warp 13 with the outer weft yarn 12 is arranged between the left and right floats of the outer warp yarns 11, and the bonding point with the inner weft yarn 22 is arranged between the left and right floats of the inner warp yarns 21 on the reverse side, so that it appears as a continuous weft weave point when viewed from the front.

[0016] Furthermore, the abrasion-resistant yarn is an abrasion-resistant double-filament twisted-in opposite-direction wrapped yarn. The core yarn of the abrasion-resistant double-filament twisted-in opposite-direction wrapped yarn is combed cotton 18.5tex yarn, wrapped with two polyester filaments of different twist directions and the same specifications, with the polyester filaments having a specification of 38.9dtex / 144F. The two polyester filaments form a mesh-like cross-wrapping structure on the outside of the core yarn, which greatly enhances the structural stability of the yarn. The unique mesh structure can effectively reduce the wear of the short fiber core yarn caused by external friction, which greatly helps to improve the abrasion resistance of the yarn and the woven fabric.

[0017] Furthermore, the moisture-wicking yarn is a grooved structure yarn. Grooved structure yarn is produced by wrapping polyester hot-melt yarn and vinylon water-soluble yarn with pure cotton roving on a ring spinning machine. The wrapped yarn is then subjected to a high-temperature treatment at 110°C, where the polyester hot-melt yarn on the yarn surface is melted first. The cooled product then fixes the vinylon water-soluble yarn and the pure cotton yarn body. The vinylon water-soluble yarn is then dissolved in a high-temperature water bath. The empty spaces created by the vinylon water-soluble yarn form grooves. Because the cooled product of the melted polyester hot-melt yarn helps to fix these spaces, a relatively stable groove structure is formed on the yarn surface. The presence of the groove structure creates a capillary effect, accelerating the wicking of liquid water and facilitating the discharge of water vapor. Specifically, the average drip diffusion time is reduced by 25.04%, the average wicking height increases by 19.48% after 30 minutes, and the average moisture permeability increases by 11.56%.

[0018] Example 2 Based on Example 1, the cotton fibers in the cotton fiber yarn are herbal antibacterial and mosquito-repellent functional cotton fibers. These herbal antibacterial and mosquito-repellent functional cotton fibers are obtained by treating cotton fibers with microcapsules of mixed plant essential oils, extracts of *Nymphaea rubra* fruit, and green tea extracts as functional antibacterial and mosquito-repellent agents. The antibacterial rates against *Staphylococcus aureus*, *Escherichia coli*, and *Candida albicans* reached 98.60%, 97.22%, and 95.34% before washing and 95.42%, 93.51%, and 90.46% after 20 washes, respectively. The mosquito-repellent rates after 0 washes and 20 washes reached 78.80% and 47.80%, respectively. Due to the addition of plant extracts, some hydrophilic groups were introduced, and the aggregation structure of macromolecules was changed, thus increasing the moisture regain of the herbal antibacterial and mosquito-repellent functional cotton fibers by 1.51%, while still maintaining the good hygroscopic properties of cotton fibers.

[0019] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
