Short-process production method capable of improving crease resistance and dye uptake of fibers, yarns or fabrics

Abstract

The invention relates to a short-process production method capable of improving the crease resistance and dye uptake of fibers, yarns or fabrics. In the short-process production method, an alkali contraction step and an oxygen bleaching or cold batch padding pretreatment step for fibers, yarns or fabrics are combined under the condition of a low temperature; and working solution is composed of 80-210g / L of caustic soda, 3-30 g / L of hydrogen peroxide, 3-35 g / L of fiber bleaching nano-material composition, and the balance of water. The short-process production method has the beneficial effects of greatly shortening the production process and saving the costs of steam, water and electricity. A fiber fabric after being treated is softer and crease-resistant, and especially better in wet crease resistance and obviously improved in washing and wearing property; the crease resistant effect of the fabric treated by the method is close to advanced crease resistant effect obtained through treatment by using liquid nitrogen; the dimensional stability of the fabric is improved; the fabric feels thick, fluffy and soft; and the dosage of about 50% of softening agent can be reduced. Moreover, the dye uptake is improved by more than 30% in contrast with the traditional process; the dosage of a dye is greatly reduced; and the indexes such as COD (Chemical Oxygen Demand), chroma and the like of waste water are reduced.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a short-process production method for improving wrinkle resistance and color uptake rate of cotton fibers, cotton-containing yarns or fabrics. Background technique [0002] The anti-wrinkle or non-ironing finishing of domestic cotton and blended yarns or fabrics has always been processed on special mercerizing machines. Before mercerizing or alkali shrinking, woven fabrics need to be desized, scoured, and bleached. It needs to be boiled and bleached before anti-wrinkle. The pre-treated yarn or knitted fabric is processed on the mercerizing machine at a low temperature of about 20 degrees for short-term alkali shrinkage or mercerized anti-wrinkle processing. Due to the low temperature and short time of alkali shrinkage or mercerized anti-wrinkle processing and the high amount of caustic soda, the solution is viscous. Thickness, so that the yarn or fabric only produces 2...

Problems solved by technology

The pre-treated yarn or knitted fabric is processed on the mercerizing machine at a low temperature of about 20 degrees for short-term alkali shrinkage or mercerized anti-wrinkle processing. Due to the low temperature and short time of alkali shrinkage or mercerized anti-wrinkle processing and the high amount of caustic soda, the solution is viscous. Thick, so that the yarn or fabric only produces 20-30% surface anti-wrinkle effect, and the fabric after traditional mercerizing only partially improves the anti-wrinkle performance and coloring rate
