Description

Mao Tiaoqi-type cross-pattern jacquard velvet fabric capable of warp knitting and production process thereof Technical Field The invention relates to the technical field of textile, in particular to a warp knitting Mao Tiaoqi-type cross pattern jacquard velvet fabric and a production process thereof. Background With the continuous progress and development of society, the requirements of people on the performances of textiles are higher and higher, and the purposes of textiles tend to be diversified, such as clothing, industrial use, decoration and the like. The pile fabric is one kind of fabric with dense, upright or curled pile covered on its surface and has the structure comprising two parts, including base fabric and pile surface, with the base fabric providing support and strength and the pile surface adhered to the base fabric. The pile fabrics are various in types and various in characteristics, and the pile fabrics produced on the double-needle bar warp knitting machine have the advantages of plump and uniform pile face, high thickness and softness, high production efficiency, good warmth retention and other excellent qualities which are not possessed by other pile fabrics, and are indispensable pile fabrics in the fields of medium-high grade clothes, home furnishings, toys and the like. The double needle bar warp knitting plush is formed by one-time knitting on a warp knitting machine and then is formed by cutting down, but the existing double needle bar warp knitting plush fabric is mostly woven by adopting a 5-bar or 6-bar double needle bar raschel warp knitting machine, the front and back 4 bars are used for knitting the base fabric, and only the middle 1 or 2 bars are used for knitting the plush, so that the warp knitting plush fabric has single style, less variation and thicker plush is easy to cause insufficient air permeability and moisture permeability, and the increasingly complex requirements can not be met. Disclosure of Invention [ Technical problem ] The conventional 5-bar or 6-bar double-needle bed plush fabric has the advantages that the fluff is formed by 1 bar or 2 bars, the pattern change is less due to the fewer fluff bars, and the formed fabric structure is simpler. Technical scheme Aiming at the problems in the prior art, the invention provides a warp knitting non-falling Mao Tiaoqi type cross pattern jacquard velvet fabric and a production process thereof. The invention adopts the 7-comb-belt electronic traversing double needle bar warp knitting machine to prepare, 3 pile combs can form rich jacquard patterns by threading, and simultaneously, gaps can be formed among the pile by utilizing less threading of the pile combs, so that the air permeability and moisture permeability of the fabric are improved. The pile yarns of the fabric are firmly locked through the extension lines of the base fabric, the pile is not easy to fall off, a three-dimensional pile effect can be formed without treatments such as shearing, napping and the like, the production cost is reduced in the subsequent production process flow, and under the condition that the jacquard pattern is determined, the change of the pattern size can be realized by changing the yarn pairs and the jacquard height row numbers according to the needs, so that the product requirements are met. The technical scheme of the invention is as follows: The first object of the invention is to provide a production process of a warp knitting Mao Tiaoqi-type cross pattern jacquard velvet fabric, which comprises the following steps: s1, selecting a semi-gloss polyester DTY, a semi-gloss polyester FDY, a flat extinction polyester and a hollow extinction octagonal polyester as raw materials; s2, warping, namely warping the polyester yarns on a warping machine according to the requirements of width, transverse density and yarn threading rate and a certain number of parts; S3, weaving by a 7-comb double-needle bed Raschel warp knitting machine, wherein GB1, GB2, GB3, GB4, GB5, GB6 and GB7 are sequentially arranged from the front to the back, GB1 and GB2 are only looped by front needle mattress yarns, GB3, GB4 and GB5 are looped by front needle bed and back needle bed knitting, and GB6 and GB7 are only looped by back needle bed knitting; S4, after-finishing, ① cutting down, ② carding, ③ dyeing and finishing, ④ polishing and ⑤ shaping; S5, detecting and packaging; wherein, each sley bar organizational structure is selected and is joined in marriage and the mode of wearing yarn when warping and weaving is: GB1 comb 0-0-0/3-3-3/0-0-0/4-4-4// full penetration or 0-0-0-0/5-5-5// full penetration; GB2 comb 1-0-0/0-1-1// full penetration; GB3 comb (0-1-0-1/1-0-1-0) 12/4-4-4-4/9-9-9-9/14-14-14-14/18-18-18-18/ (22-23-22-23/23-22-23-22)12/18-18-18-18/14-14-14-14/9-9-9-9/ 4-4-4-4// 2 Is penetrated by 30 empty 11 penetrations; GB4 comb (20-21-20-21/21-20-21-20) 6/18-19-19-19/18-17-17-17/ 16-17-17-17/16-15-15-15/14-15-15-15/14-13-13-13/12-13-13-13/ 12-11-11-1
