Method for preparing invisible slub mercerized cotton wool jeans fabrics

Abstract

The invention involves a preparation method of stealth bamboo mercerized cotton or wool denim fabric. It is made of 6.7SB stealth bunchy yarn as warp yarn and 7.5S cotton and wool blended yarn as the weft yarn, warp yarn is darned with weft yarn through ball warping and after pencil dyeing and drafting, then singeing, desizing, drying, mercerising, water scrubbing and completing. Said stealth bunchy yarn is cotton yarn and its bamboo joint magnification is below 1.5 times; the cotton are 30% and wool 70% in weft yarn, cotton are 75.8%, wool 24.2% in face fabric. The process of pencil dyeing of warp yarn is: stealth bunchy yarn is affinaged in two affinaging grooves and scrubbed in two water grooves successively through ball warping and axis ball warping, then transported to the seventh groove to dyeing, the 32nd roll to high altitude airing oxygenating, the third groove to watering and the first groove to softening; then drying, dropping ingrain knitting yarns in barrels, opening warp beam, starching, drying, leasing and wrapping into weaver. The method can be organized well and the fabric color effect is fine.

Description

technical field [0001] The invention relates to a denim fabric, in particular to a preparation method of an invisible slub mercerized cotton wool denim fabric. It belongs to the field of textile technology. Background technique [0002] With the improvement of people's living standards, various high-quality and high-grade functional fabrics have emerged, such as the invisible slub denim fabric in denim fabrics, which is in line with the trend of the times. The requirement for invisible slub denim fabric is that the ratio of slubs should be less than 1.5 times. The effect of the finished yarn should be close to that of plain yarn. The surface should have the effect of bamboo knots. Due to the special dyeing requirements of invisible slub cotton wool denim, the color of the finished fabric looks like super dark blue and a little black, but after stonewashing, the color feeling is obviously different from super dark blue, and the surface of the cloth is glossy. Not blue but ...

Problems solved by technology

If the conventional method of producing denim is used to produce invisible slub denim fabric, not only the color effect cannot meet the design requirements, but also the weavability is poor
