[0046] Example 1

[0047] Reference Figure 1 This embodiment discloses a warp knitted microfiber suede fabric and a processing method thereof. The fabric structure comprises a surface layer 1, a jacquard layer 2, an intermediate layer 3 and a bottom layer 4. The specific physical structure can be found in Figure 6 The jacquard layer 2 is made by using sea-island composite yarn weaving technology to form a suede jacquard layer 2 with a specific texture. Figure 7 The island-in-the-sea composite yarn is composed of the island-in-the-sea yarn 6 and the high shrinkage yarn 7. Figure 5 As shown, the island yarn 6 includes island-phase fibers 62 and soluble sea-phase fibers 61 surrounding the island-phase fibers 62. In this embodiment, the island-phase fibers 62 are made of ordinary polyester fibers, and the sea-phase fibers 61 are made of alkali-soluble polyester. The specification of the island composite yarn is 105D / 36F. Among them, the specification of the island yarn 6 is 75D / 24F. At a temperature of 120°C, it takes about 30 to 40 minutes to hydrolyze the sea-phase fibers 61. Each F in 24F is decomposed into 37F, and a total of 888F is decomposed to improve the subsequent tight velvet effect. The high shrinkage yarn 7 uses 30D / 12F FDY high stretch yarn, which can play a shrinkage and tightening role on the hydrolyzed yarn, thereby optimizing the velvet effect of the suede jacquard layer 2. As for the processing flow of warp-knitted microfiber suede fabrics, please refer to Figure 2 , the specific steps are as follows:

[0048] Weaving of surface layer 1: using at least one comb, GB2: warping P-FDY100D / 36F polyester environmentally friendly bright yarn, 6 bobbins, each with 496 yarns, GB2 yarn is fully threaded into the machine, the gear warp amount is 2250m / lacquer, the warp weave is variable 2-3 / 1-1 / 1-0 / 1-1 / / , and the content of GB2 environmentally friendly bright yarn accounts for about 18.839%; 2 combs can also be used to form regular mesh holes on the surface of surface layer 1 according to design requirements using an empty threading process to improve the air permeability of the entire fabric.

[0050] JK4: Warping P-DTY220D / 72F semi-bright new island yarn, 6 bobbins, 248 yarns each, JK4 yarn is threaded into the machine in a 1-through-1-empty manner, gear feed amount 2180mm / lacquer, plain warp weave 0-1 / 1-1 / 2-1 / 1-1 / / , JK4 new island yarn content accounts for about 20.078%.

[0051] The suede jacquard layer 2 is formed by weaving, and the position of the suede jacquard can be customized and can also be designed in a local position.

[0052] Weaving of middle layer 3: GB5: warping P-DT30D / 1F environmentally friendly monofilament yarn, 6 bobbins, 496 yarns each, GB5 yarn is fully threaded into the machine, gear warp amount is 7200mm / lacquer, the warp weave is changed 1-0 / 2-1 / / 2-3 / 1-2 / / , and the content of GB5 environmentally friendly monofilament is about 18.085%.

[0053] The middle layer 3 formed by warp knitting allows the woven suede to achieve customized Q elasticity, thickness and height of the hair height, breaking through the previous single-layer suede fabric, achieving double-layer fabric and customized hair height, which is beneficial for later use in mattresses, sofa cushions, car seat cushions, etc. It is affordable, environmentally friendly, wear-resistant and has a long service life, solving the problems of current animal hair mats being not resistant to light and difficult to clean.

[0054] Weaving of bottom layer 4: GB6: warping P-DTY75D / 36F semi-gloss environmentally friendly low-elastic light mesh (recycle) yarn, 6 bobbins, 496 yarns each, GB6 yarn is fully threaded into the machine, gear warp amount 1500m / lacquer, chain weave 1-1 / 1-0 / 0-0 / 0-1 / / , the content of GB6 polyester white low-elastic light mesh yarn accounts for about 9.419%.

[0055] GB7: Warping P-DTY75D / 36F semi-gloss environmentally friendly low-elastic light mesh (recycle) yarn, 6 bobbins, 512 yarns each, GB7 yarn is fully threaded into the machine, the gear warp feed rate is 2150m / lacquer, the warp weave changes are 2-2 / 2-3 / 2-2 / 1-0 / / , the content of GB7 polyester white low-elastic light mesh yarn is about 13.501%.

[0057] Reference Figure 3 This embodiment discloses a warp knitted microfiber suede fabric and its processing method, involving fabric structure design and production process. The fabric consists of a surface layer 1, a jacquard layer 2, a fixed layer 5 and a bottom layer 4. The jacquard layer 2 is woven with island-in-the-sea composite yarn to form a unique suede texture. Figure 7The island-in-the-sea composite yarn is composed of the meshed island-in-the-sea yarn 6 and the high shrinkage yarn 7. Figure 5 As shown, the island-in-the-sea composite yarn 6 comprises island-phase fibers 62 and soluble sea-phase fibers 61. Island-phase fibers 62 are conventional polyester fibers, while sea-phase fibers 61 are alkali-soluble polyester. The specifications of the island-in-the-sea composite yarn are 105D / 36F. The specifications of the island-in-the-sea composite yarn 6 are 75D / 24F. At 120°C, it takes approximately 30 to 40 minutes for the sea-phase fibers 61 to hydrolyze. The high-shrinkage yarn 7 is 30D / 12F FDY high-stretch yarn. The shrinkage of the high-stretch yarn tightly gathers the hydrolyzed yarn, enhancing the velvety feel of the suede jacquard layer 2.

[0058] Regarding the processing method of the fabric, according to Figure 4 As shown, the main steps are as follows:

[0059] Weaving of surface layer 1: GB1: warping P-DT0.08 / 1F bright environmentally friendly polyester monofilament yarn, 6 bobbins, 512 yarns each, GB1 yarn is fully threaded into the machine, the gear warp amount is 1600m / lacquer, the chain weave is 1-0 / 1-1 / 0-1 / 1-1 / / , and the content of GB1 environmentally friendly polyester monofilament yarn accounts for about 7.703%.
