Elastic dobby fabric with different warp and different weft and its weaving process

Abstract

The invention discloses warp and weft different elastic mini Jacquard fabric and a weaving process thereof. Warps of the fabric are pure cotton yarns and pure polyester yarns; wefts of the fabric are the pure cotton yarns and elastic yarns; the technological process comprises spooling, warping, warp sizing, denting, weaving and trimming; during the warp sizing, the pure cotton yarns and the pure polyester yarns can performed sizing, dye which can be washed out is added to the pure cotton serous fluid to perform dying, and antistatic agent is added to the pure polyester serous fluid; during denting, the pure polyester yarns are weaved in the front area to guarantee a small opening technology in weaving and reduce up and down friction and a selvage structure is in a double-tank side weaving method; during weaving, a yarn separator is used to separate the yarns, the pure cotton yarns are arranged on the upper layer of the yarn separator, the pure polyester yarns are arranged on the lower layer of the yarn separator, and identification is convenient and error is not easy to occur during weaving. The weaving process of the warp and weft different elastic mini Jacquard fabric has the advantages of enabling the warp and weft different elastic mini Jacquard fabric to be weaved in a conventional air jet loom, being simple in technology and small in weaving difficulty, well guaranteeing fabric quality and increasing one functional weaving product for the weaving field.

Description

technical field [0001] The invention relates to the technical field of textile production and weaving, in particular to a different warp (JC32, T30 fine denier) different weft (JC32+40D, T30 fine denier) elastic dobby (2 / 2+3 / 1+1 / 3 combined tissue) fabrics and their weaving techniques. Background technique [0002] In the existing weaving technology, the elastic dobby fabric woven with two different warp yarns and different weft yarns is very immature, and some key technologies are not up to standard in the production process. For example, in the reeding process, the warp yarns of the two kinds of yarns cannot be distinguished clearly, resulting in wrong warp and defective fabrics; when the two warp yarns are pure cotton yarns and pure polyester yarns, the pure polyester warp yarns are difficult to sizing and easy to sizing in the sizing process. The problem of static electricity; in the weaving process, the pure polyester warp yarn is prone to pilling, causing warp breakage...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problems such as defects in elastic dobby fabrics woven from existing two different warp and weft yarns, the object of the present invention is to provide a kind of elastic dobby jacquard fabric with different warp and different weft and its weaving process. To achieve the purpose of improving product quality
