A kind of production process of weft stretch washed velvet fabric

Abstract

The invention discloses a production process of weft elastic washed velvet fabric, which comprises the following steps: step S1 warp yarn preparation, step S2 warping, step S3 warp beam dyeing pretreatment, step S4 warp beam dyeing, step S5 warp beam soaping, Step S6 foam sizing, step S7 weft yarn loosening, step S8 weft yarn pretreatment, step S9 weft yarn dyeing, step S10 weft yarn soaping, step S11 weaving, step S12 post-finishing. The production process of a kind of weft elastic washed velvet fabric involved in the present invention uses super imitation cotton filament and polyester POY as the warp yarn to carry out the mixed fiber yarn prepared by grid-connected two-for-one twisting, uses tencel and Coolmax fiber as the covering layer, and spandex as the The core yarn of the core yarn. And satin weaving is used, so that one side of the fabric shows mixed filaments, and the other side shows core-spun yarns. After washing and other post-treatments, the effect of washing can be formed on one side of the wet filaments, and the core-spun yarn side It has good moisture absorption and dehumidification function, thus solving the disadvantage of poor moisture absorption and dehydration of traditional washed fleece fabrics.

Description

technical field [0001] The invention relates to the technical field of textile fabric production, in particular to a production process of weft elastic washed velvet fabric. Background technique [0002] The raw materials of washed fleece fabrics generally use FDY and POY to prepare mixed fiber yarns through grid-connecting and two-for-one twisting processes. The orientation and crystallization of FDY molecules are higher, so its strength is better than POY. After the alkali reduction treatment, the strength loss of FDY is small, the strength of POY is seriously reduced, and some monofilaments are broken. The polyester FDY and POY are combined and twisted to make the warp yarn and the low-twist low-elasticity yarn. After alkali reduction and water washing, a layer of fine fluff is formed on the surface of the fabric due to the breakage of the POY monofilament. It can form washed fleece fabric. Since the washed velvet fabric is made of polyester fiber, the fabric has poor ...

Problems solved by technology

Because the washed velvet fabric is made of polyester fiber, the fabric has poor moisture absorption and antistatic effects
