Description

Technical Field

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

[0002] Warp knitting is an important branch of knitting technology, where parallel yarns are fed into working needles along the warp direction to form loops and create fabric. Unlike weft knitting, which uses a horizontal loop-forming method, warp knitting uses a warp beam to feed yarn, allowing multiple yarns to work together to form a continuous longitudinal loop structure. It is also an important raw material for clothing fabrics. Spandex filaments are widely used in clothing fabrics due to their excellent elasticity and elastic recovery rate. Brushed yarn refers to yarn whose fibers are stretched to exhibit a special texture, offering comfort and a distinctive appearance. There are no reports of warp-knitted fabrics made from brushed yarn and spandex filaments; therefore, how to prepare a warp-knitted fabric using brushed yarn and spandex has become a problem to be solved.

[0015] Figure 1 This is a schematic diagram of the spandex warp-knitted fabric involved in Example 1;

[0016] Figure 2 This is a schematic diagram of the spandex warp-knitted fabric involved in Example 2. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combination Figure 1 This embodiment will be described in detail below. The spandex warp-knitted fabric involved in this embodiment includes a composite base fabric layer 1 and a skin-friendly fabric layer 2, specifically composited by a PU hot melt adhesive web film, the surface density of which is 8 grams per square meter.

[0020] The base fabric layer 1 comprises an integrally woven surface layer 11 and a bottom layer 12; the surface layer 11 is made of napped yarn, and the bottom layer 12 is made of spandex filament. The yarn padding number of the surface layer 11 is 0-1 / 2-1 / / , and the yarn threading pattern is full threading. The yarn padding number of the bottom layer 12 is 1-0 / 1-2 / / , and the yarn threading pattern is every other yarn. The yarns used in the surface layer 11 and the yarns used in the bottom layer are interwoven during the weaving process.

[0021] Furthermore, the chemical fiber filament is either polyester filament or nylon filament. In this embodiment, polyester filament is selected. The polyester filament is matte polyester filament, specifically with a fineness of 75D / 72F. The spandex filament has a fineness of 40-70D, and in this embodiment, it is 40D. The areal density of the base fabric layer 1 is 120 grams per square meter.

[0022] The napped yarn includes a core yarn and a fixing yarn wound around the outside of the core yarn, with a twist of 6-10 twists per centimeter; the core yarn includes chemical fiber filaments, and the fixing yarn is combed long-staple cotton yarn; a bundle of cashmere fibers is 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. The cashmere sliver forms large, sparse loops, which are then broken into finer, longer loops by a napping machine and attached between the core yarn and the fixing yarn, thus creating a loop-nap fancy yarn.

[0023] The skin-friendly fabric layer 2 is woven from silk core-spun yarn using a warp-knitted plain weave. The silk core-spun yarn includes spandex filaments and silk yarn covering the spandex filaments. Specifically, the silk yarn has a fineness of 2 / 20 / 22D. The spandex filaments have a fineness of 40D. The silk yarn provides excellent skin-friendly properties, thereby improving the overall comfort and added value of the fabric.

[0024] Example 2

[0025] Combination Figure 2 This embodiment will be described in detail below. The spandex warp-knitted fabric involved in this embodiment differs from that in Embodiment 1 in that a zinc oxide nanofilm layer 13 is deposited on one side of the bottom layer 12 of the base fabric layer 1 using vacuum deposition technology. 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 possesses waterproof and stain-resistant properties, allowing stains and dust on the surface of the curtain fabric to be removed with a gentle wipe. In this embodiment, the thickness of the zinc oxide nanofilm layer 3 is approximately 50 nm.

[0026] Another difference from the first embodiment is that the core yarn also includes three sets of copper-modified antibacterial and anti-mite PA6 fiber filaments twisted together with the chemical fiber filaments.

[0027] 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.
