Abstract

The invention relates to the technical fields of textile printing and dyeing and particularly relates to a one-step-method differential dyeing process for a cellulosic fiber textile. The one-step-method differential dyeing process comprises the following specific processes: preparing a cellulosic fiber modified working solution, adding the cellulosic fiber modified working solution into a dyeing machine; heating the modified working solution in the dyeing solution to 60-80 DEG C, and maintaining the temperature; carrying out water washing, neutralization and dehydration, and drying for later use; mixing with unprocessed fibers, and spinning; weaving into textiles of different structures; preparing a scouring and bleaching working solution, adding the scouring and bleaching working solution into an overflow dyeing machine; putting the textiles into the overflow dyeing machine; heating the scouring and bleaching working solution in the overflow dyeing machine to 80-98 DEG C, and maintaining the temperature; carrying out water washing and dehydration, and drying for later use; dyeing the textiles; and carrying out normal-temperature dyeing, liquid discharging, water washing, soaping, water washing and dehydration for later use. Compared with the prior art, the one-step-method differential dyeing process has the advantages that a cellulosic fiber cationization theory and a process are researched and applied to loosened fibers, graft fibers and common fibers are blended, spun and woven, and then a white-texture flower yarn-patterned fabric is prepared by virtue of a one-step method.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a one-step differential dyeing and finishing process for cellulose fiber fabrics. Background technique [0002] Color spun yarn refers to the yarn containing two or more fibers of different colors and spun after a specific process of mixing and spinning. The fabric composed of colored spinning has a three-dimensional mixed color style, the color is natural and subtle, and has a strong hazy feeling, which can meet the personalized, diversified and fashionable clothing consumption concept of modern consumers, and has a strong competitive advantage in the market. The future development prospect is broad. At present, the output of color-spun yarn is not high, and its proportion is relatively low compared with the whole yarn production capacity. [0003] The traditional color spinning adopts the processing mode of "dyeing first, then spinning": the loose fibers a...
