Description

Technical Field

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

[0002] Warp-knitted fabrics can be used as clothing and home furnishing fabrics. When used as home furnishing fabrics, such as sofa upholstery or toy cushions, a napping process is typically applied to create a fluffy layer on the surface, improving comfort. Polyester and cotton fibers are commonly used synthetic and natural fibers in the textile industry, widely applied in clothing and home furnishing fabrics. However, cotton fibers are limited in length for napping, resulting in shorter pile and a tendency to shed. If polyester is used as the napping fiber, its comfort is less than that of natural fibers due to its synthetic nature. Furthermore, napping can damage the strength of the warp-knitted fabric. Therefore, increasing the strength and tear resistance of napped warp-knitted fabrics is also a challenge. The problem to be solved is how to prepare a polyester-cotton warp-knitted fabric with a soft, fluffy surface suitable for home furnishings such as toy cushions, while also possessing good tear resistance. Utility Model Content

[0003] The purpose of this invention is to provide a polyester-cotton warp-knitted fabric, which uses brushed yarn and cashmere fibers for the pile, providing comfort, and the composite planar three-dimensional fabric has good tear resistance.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model discloses a polyester-cotton warp-knitted fabric, characterized in that it comprises a composite base fabric layer and a planar triaxial fabric layer; The base fabric layer includes a face comb, a middle comb, and a bottom comb; the bottom comb and the middle comb are made of polyester-cotton blended yarn.

[0012] The markings in the diagram are explained as follows: 1-base fabric layer; 2-planar triaxial fabric; 21-copper modified antibacterial and anti-mite PA6 fiber yarn; 3-zinc oxide nanofilm layer. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1 Combination Figure 1 and Figure 2 This embodiment will be described in detail below. The polyester-cotton warp-knitted fabric involved in this embodiment includes a composite base fabric layer 1 and a planar triaxial fabric layer 2, which are specifically composited by a hot melt adhesive web film, and the material is PUR or EVA.

[0015] The base fabric layer includes a face comb, a middle comb, and a bottom comb; the bottom and middle combs are made of polyester-cotton blended yarn; the face comb is made of napped yarn, which includes a core yarn and a fixing yarn wrapped around the outside of the core yarn, with a twist of 6-10 twists per centimeter, selected in this embodiment as 8 twists per centimeter, which has a higher twist and can improve the clamping force. The core yarn is made of polyester-cotton blended yarn, specifically polyester 35 / 65, with a fineness of 40 count. The fixing yarn is a chemical fiber filament, specifically 75D / 36F polyester DTY filament. Cashmere fiber bundles are fixed between the core yarn and the fixing yarn. The napping process involves preparing the core yarn, fixing yarn, and cashmere sliver on a fancy twisting machine, forming large and sparse looped yarns, which are then broken into finer and longer loops by the napping machine and attached between the core yarn and the fixing yarn, thereby producing looped napped fancy yarn.

[0016] Furthermore, the planar triaxial fabric layer 2 is composed of three groups of copper-modified antibacterial and anti-mite PA6 fiber yarns interwoven at a 60° angle. Most woven fabrics are composed of yarns interwoven in two mutually perpendicular directions. When the fabric is subjected to a tensile force at a 45° angle to the warp or weft yarns, the tensile modulus of the woven fabric differs significantly from that when subjected to warp or weft tensile forces. However, triaxial fabrics, due to the presence of three systems of yarns interwoven at 60° angles, achieve isotropic properties. That is, regardless of the direction of stress, the deformation of the triaxial fabric is uniform in all directions. Therefore, triaxial fabrics do not have the weak points in shear and tensile strength found in two-dimensional fabrics. Furthermore, when subjected to impact, the deformation of the triaxial fabric exhibits uniform and identical strain. In this embodiment, a planar triaxial fabric with a basic structure is used.

[0017] Furthermore, the padding yarn number of the face comb is 1-0 / 0-1 / 1-0 / 1-3 / 3-1 / 1-3 / / , and the yarn threading pattern is full threading; the padding yarn number of the middle comb is 0-0 / 1-1 / 0-0 / 3-3 / 2-2 / 3-3 / / , and the yarn threading pattern is full threading; the padding yarn number of the bottom comb is 2-3 / 1-0 / 2-3 / 1-0 / 2-3 / 1-0 / / , and the yarn threading pattern is full threading.

[0018] Example 2 Combination Figure 3 This embodiment will be described in detail below. One difference between this embodiment and Embodiment 1 is that the fixed yarn further includes core-sheath type polyester filaments twisted together with chemical fiber filaments. These core-sheath polyester filaments comprise a core layer and a sheath layer. The sheath layer is low-temperature PET, and the core layer is conventional PET. Low-temperature PET has a melting point of 80-110℃, while conventional PET has a melting point of 250-255℃. During heat treatment of the fabric, the low-temperature PET melts, thereby bonding the adjacent cashmere fibers and reducing shedding.

[0019] Another difference from Example 1 is that the core yarn also includes antibacterial nylon filament twisted together with the polyester-cotton blended yarn. The antibacterial nylon filament used has a fineness of 75D / 72F and can provide a certain antibacterial ability.

[0020] Another difference from Embodiment 1 is that a zinc oxide nanofilm layer 3 is attached to the surface of the planar triaxial fabric layer 2 on the side away from the base fabric layer 1. The zinc oxide nanofilm layer 3 is formed by directly depositing multiple layers of nanoscale metals or metal oxides onto the fabric surface using vacuum deposition technology. When bonded to the fabric, it forms a strong chemical bond, exhibiting water resistance and abrasion resistance. Furthermore, due to its nanofilm nature, it also has waterproof and stain-resistant properties, allowing stains and dust on the curtain fabric surface to be removed with a gentle wipe. In this embodiment, the thickness of the zinc oxide nanofilm layer 3 is approximately 50 nm.

[0021] 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.
