Abstract

The invention relates to the field of textile dyeing and provides a nylon-cotton dyeing method based on a one-path process, comprising the steps of (1) preparing base cloth; (2) pretreating, to be specific, adding, under the water-bath ratio of 1:10, 5-10 g / L of 30% hydrogen peroxide and 0.5-1.5 g / L of hydrogen peroxide stabilizer, as well as 1-2 g / L of cotton purifying enzymic preparation, wherein the hydrogen peroxide stabilizer is composed of sodium silicate, magnesium sulfate and EDTA in a ratio of 1:1:1; (3) dyeing, to be specific, dyeing a dyeing composition of 0.5-1 g / L of penetrating agent H-95, 1.0-2.0 g / L of dye-retarding agent ERIONAL RF, 1.0-2.0 g / L of sodium dihydrogen phosphate, 20-35 g / L of edible salt, 0.2-1% of leveling agent LD-VRD, 1-2% of EuNeothol dye, 1-2% of NovacronLS dye, and 5 g / L of sodium carbonate under the bath ratio of 1:10; (4) soaping; (5) scutching and drying; (6) setting; (7) inspecting the finished product. The method herein is suitable for the dyeing of base cloths containing 60-80% of nylon and 20-40% of cotton and woven with a nylon-cotton machine.

Description

technical field [0001] The invention relates to the field of textile dyeing, in particular to a nylon-cotton one-bath dyeing method. Background technique [0002] Nylon cotton is a blended fabric of nylon and cotton, with a nylon content of more than 50%. It combines the advantages of the two fibers. It not only has the characteristics of nylon's fatigue resistance and strong body, but also maintains the breathability and hygroscopicity of cotton. And the advantages of wearing comfort, and favored by consumers, has become an internationally popular fashion fabric with a good market prospect. However, due to the large difference in physical structure and chemical properties between nylon fiber and cotton fiber, the dyeing and finishing process is more complicated, the dyeing is difficult, and the technical requirements are high. For a long time, nylon cotton dyeing has adopted the two-bath dyeing process of dyeing cotton first and then over-dyeing nylon, such as reactive / aci...
