Dyeing technology for polyester cotton according to dispersive bath method

Abstract

The invention discloses a dyeing technology for polyester cotton according to a dispersive bath method. The technology comprises the following steps: 1) treating disperse dyes, wherein the step of treating the disperse dyes comprises immersing and rolling the disperse dyes, preliminarily drying the disperse dyes which are immersed and rolled with infrared rays, drying the disperse dyes which are preliminarily dried with hot air, conducting hot melt baking on the disperse dyes which are dried and cooling the disperse dyes which are hot melt baked; 2) treating reduced dyes, wherein the step of treating the reduced dyes comprises immersing and rolling suspended substances of the reduced dyes, preliminarily drying the suspended substances which are immersed and rolled with the infrared rays, drying the suspended substances which are preliminarily dried with a drying cylinder, immersing and rolling a reduction solution, steaming the reduced solution which is immersed and rolled, drip washing the reduced solution which is steamed, oxidating the reduced solution which is drip washed, washing the reduced solution which is oxidated with water, washing the reduced solution which is washed with soap, washing the reduced solution which is washed with the water and drying the reduced solution which is washed. The technology disclosed by the invention adopts the dispersive bath method to treat dyeing, according to the method, the dyeing effect is good, the level dyeing degree is high, the dyeing fastness is high, the situation of color fading is avoided, and the quality is good.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a polyester-cotton dispersion-bath dyeing process. Background technique [0002] With the continuous development of science and technology, textile fabrics that meet people's different needs emerge in an endless stream to meet the needs of consumers and play an increasingly important role in people's daily life. [0003] The existing polyester-cotton dyeing is usually relatively simple in the dyeing process, and the dyeing effect of the finished polyester-cotton fabric is usually unsatisfactory, and the phenomenon of fading often occurs during washing, causing other clothing to be affected by fading and cannot be used . Therefore, the production technology of a kind of non-fading, high-quality polyester-cotton dyed fabric of research and development becomes the problem urgently to be solved. Contents of the invention [0004] The object of the present invention is to provide a kind of dyei...
