High-elastic low-shrinkage jean cloth and technology for same

Abstract

The invention discloses high-elastic low-shrinkage jean cloth and a technology for the same. The jean cloth is interweaved by warp yarns and weft yarns in a principle of three warp yarns above and one weft yarn under. The concrete processes are spooling, warping, sizing and dyeing linkage, weaving, checking gray fabric, after-treatment processing, checking finished product and packing. The invention relate to high-elastic low-shrinkage jean cloth and a technology for the same. A 3 / 1 twill-weave is applied; cotton bale T400 warps spandex weft yarns, short fiber pure polyester warps the spandex or blending cotton type warps spandex weft yarns; denier of the spandex is 70D to 105D; draft multiple is 3.5 to 4.5; warp direction tightness of the yarns on a machine is 45% to 75%; weft direction tightness of the yarns on the machine is 38% to 55%; the blank cloth is post-treatment processed according to the concrete processes, so finished product amplification can be narrowed, so weft shrinkage can be reduced; a problem produced during clothing and washing water processing links can be effectively solved; with specific weft-warp yarns, specific weaving machining technology and specific post-treatment process, weft extension of the jean cloth can reach no less than 35%, reversion rate no more than 2.5% and weft shrinkage rate no more than 10%.

Description

technical field [0001] The invention relates to the field of textile fabrics and the field of textile technology, in particular to a high-elasticity low-shrinkage denim and its technology. Background technique [0002] At present, the best-selling high-elastic denim fabrics on the market have a weft extension of more than 30%, but the weft shrinkage is generally more than -12%, which will lead to difficulties in the manufacture of garments and increased wear and tear, and loss of elasticity will occur during the washing process. Therefore, it is necessary to invent a denim fabric with high elasticity and low shrinkage to meet the market demand and can effectively solve the problems in the garment making and washing process. The present invention adopts specific warp and weft yarns, specific weaving machine technology and specific The finishing process can meet the requirements of denim weft extension ≥ 35%, recovery rate ≤ 2.5%, and weft shrinkage ≤ -10%. Contents of the i...
