AI Technical Summary
Existing textile fabrics have problems such as weak pile feel, unstable structure, and easy yellowing when woven in one piece, which reduces their practicality.
The sandwich mesh fabric is woven in one piece using a warp knitting machine. By combining different yarns and combing structures in the face layer, middle layer, and bottom layer, a napped fabric with a strong three-dimensional effect and stable structure is formed. The yarn distribution is controlled by different movement modes of the ground comb and the amount of warp feed from the gears, so that plain weave and napped fabric can coexist.
It achieves a three-dimensional and structurally stable napped fabric, increases the diversity and skin-friendliness of the fabric, reduces costs and time, solves the limitations of one-piece weaving in the market, and conforms to the trend of soft, delicate and lightweight fabrics.

Abstract
Description
Technical Field
[0001] This invention relates to the field of textile technology, and in particular to an integrally woven napped sandwich mesh fabric and its weaving method. Background Technology
[0002] With rapid economic development, consumers' spending power has gradually increased, and their demands for clothing have also risen. Fabrics on the market are increasingly meeting these needs. However, there are currently many problems with existing textile fabrics and textile processes. For example, there are many fleece-textured textiles, such as towels and garments with partial fleece embellishments. Fleece-textured fabrics in the jacquard category are basically post-processed, involving splitting, napping, or piecing together fabric samples. Spandex core-spun yarn is sometimes used to make fleece mesh, but the temperature of spandex core-spun yarn is difficult to control, and it is prone to shrinkage and yellowing. Because most fleece fabrics on the market are woven in a single-sided manner, their physical properties are limited, leading to reduced practicality. Summary of the Invention
[0003] The purpose of this invention is to provide an integrally woven pile sandwich mesh fabric and its weaving method, which can solve the problem that previous processes could not integrally weave pile fabrics with a strong three-dimensional effect and stable structure.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrally woven pile sandwich mesh fabric, comprising a mesh body integrally woven by a warp knitting machine, the mesh body comprising a face layer, a middle layer, and a bottom layer, the face layer being woven by the chain blocks of the jacquard machine or the ground comb using any weave, the middle layer being woven by yarns using a weave connecting the face layer and the bottom layer, the bottom layer being woven by the chain blocks of the jacquard machine or the ground comb using any weave, and the bottom layer or the face layer being made into a pile-like layer as required.
[0005] Furthermore, the surface layer yarn is made of 70-200D multifilament yarn, the middle layer yarn is made of 20-100D transparent monofilament or multifilament yarn, and the bottom layer is made of 70-200D multifilament yarn interwoven together.

[0007] Step S1, Setting up the combs: Use a warp knitting machine with at least 7 ground combs for knitting, and set the ground combs GB1, GB2, GB3, GB4, GB5, GB6 and GB7 in sequence from the front needle bed to the back needle bed.
[0008] Step S2, Yarn threading method: Ground comb GB1 threads the yarn without threading it; ground comb GB2 threads the yarn by combining two yarns together and threading it with a 1-thread-1-no-thread method; ground comb GB3, ground comb GB4, ground comb GB5, ground comb GB6 and ground comb GB7 all thread the yarn with a 1-thread-1-no-thread method.
[0009] Step S3, weaving: Ground comb GB2 and ground comb GB3 form the surface layer and pile layer on the front needle mattress yarn, ground comb GB4 and ground comb GB5 form the middle layer on the front and back needle mattress yarns, and ground comb GB6 and ground comb GB7 form the bottom layer on the back needle mattress yarn. Ground comb GB2 and ground comb GB3 work together to weave and form pile and plain weave.
[0010] Furthermore, each of the ground combs in step S2 has 6 heads, each head of ground comb GB2 has 630 yarns, and each head of ground comb GB3, ground comb GB4, ground comb GB5, ground comb GB6 and ground comb GB7 has 315 yarns.
[0011] Furthermore, in step S2, the ground comb GB2 uses 70-200D transparent monofilament or multifilament yarn with a yarn content of 26.5%; the ground comb GB3 uses 100-200D transparent monofilament or multifilament yarn with a yarn content of 9.2%; the ground comb GB4 uses 20-150D transparent monofilament or multifilament yarn with a yarn content of 16.1%; the ground comb GB5 uses 20-150D transparent monofilament or multifilament yarn with a yarn content of 16.1%; the ground comb GB6 uses 70-200D transparent monofilament or multifilament yarn with a yarn content of 15.9%; and the ground comb GB7 uses 70-200D transparent monofilament or multifilament yarn with a yarn content of 15.9%.
[0012] Furthermore, in step S3, the ground comb GB2 has a warp section structure, the ground comb GB3 has a braided chain structure, the ground comb GB4 and GB5 have a comb structure, and the ground comb GB6 and GB7 have a warp section structure to form a mesh.
[0013] Furthermore, in step S3, the padding yarn numbers for the ground comb GB2 warp section are: 7-6 / 5-5 / 4-3 / 2-2 / 0-1 / 2-2 / 3-4 / 5-5 / 7-6 / 5-5 / 4-3 / 2-2 / 0-1 / 2-2 / 3-4 / 5-5 / 7-6 / 5-5 / 4-3 / 2-2 / 0-1 / 2-2 / 3-4 / 5-5 / / , and the padding yarn numbers for the ground comb GB3 braided chain section are: 0-1 / 1-1 / 1 -0 / 0-0 / / , the padding yarn numbers for GB4 and GB5 ground comb comb structures are: 0-1 / 1-2 / 3-2 / 2-1 / / , the padding yarn numbers for GB6 ground comb comb structures are: 1-1 / 0-1 / 2-2 / 3-2 / 1-1 / 1-2 / 2-2 / 3-2 / / , and the padding yarn numbers for GB7 ground comb comb structures are: 2-2 / 3-2 / 1-1 / 0-1 / 2-2 / 2-1 / 1-1 / 0-1 / / .
[0014] Furthermore, in step S3, the gear feed rate corresponding to the ground comb GB2 is 2880 mm / lac, the gear feed rate corresponding to the ground comb GB3 is 1510 mm / lac, the gear feed rates corresponding to the ground comb GB4 and GB5 are both 6600 mm / lac, and the gear feed rates corresponding to the ground comb GB6 and GB7 are both 1730 mm / lac.
[0015] The beneficial effects of this invention are as follows: Compared with the prior art, this invention provides an integrated woven pile sandwich mesh fabric and its weaving method. It utilizes the principle of warp knitting machines for process design, resulting in a richer product range. The pile is woven using the special characteristics of continuous blocks and machine adjustments, with chain blocks controlling the fabric to achieve both plain weave and pile effects. This retains the original style of the sandwich mesh fabric while increasing the diversity of pile effects. It overcomes the limitations of older machines that could only produce simple, regular mesh openings and plain weaves on the face and bottom. Instead, it utilizes new process characteristics to create a coexistence of pile and plain weave effects. The pile effect is achieved through the movement of the ground comb and drawn yarn opening structure, making the sandwich mesh fabric more colorful, three-dimensional, skin-friendly, lightweight, and innovative. This addresses a major market demand. The integrated woven pile sandwich mesh fabric offers high versatility, significantly improving upon the limitations of previous processes, while reducing costs, labor, and time. It boasts advantages such as strong physical properties, softness, skin-friendliness, delicacy, and lightness, perfectly aligning with a major trend in textiles. Attached Figure Description
