Abstract
The invention discloses a polyester/cotton knitted fabric short-flow dyeing and finishing process method including the following steps: (one), one-bath pretreatment: soaking a polyester/cotton fabricin a pretreatment finishing liquid, treating for 45 min at the temperature of 95-100 DEG C, then cooling, discharging a waste liquid, and washing with water; and (two), dyeing: making a dye for polyester component dyeing and an auxiliary agent into a solution with the pH value of 5 in a dyeing vat, immersing the polyester/cotton knitted fabric in the dyeing solution, carrying out heat preservationfor 40 min under the condition of the temperature of 130 DEG C, and completing dyeing of the polyester part in the fabric; adding the reactive dye and anhydrous sodium sulfate, carrying out heat preservation for 30 min at the temperature of 65 DEG C, then adding 20 g/L of sodium carbonate, carrying out heat preservation for 30 min, then adding 10 g/L of sodium carbonate, carrying out heat preservation for 30 min, soaping, and washing with water; and post-finishing, preparing a post-finishing liquid in a material tank of a setting machine, immersing the dyed polyester/cotton fabric in the post-finishing liquid, padding by a padder, and drying at the temperature of 175-185 DEG C.
Description
technical field [0001] The invention relates to a textile dyeing and finishing process, in particular to a short-process dyeing and finishing process of polyester-cotton knitted fabrics, belonging to the field of textile dyeing and finishing processes. Background technique [0002] Polyester-cotton knitted fabric highlights the crispness of polyester and the dryness and softness of cotton fiber. It is tall and straight, not easy to wrinkle, easy to wash and quick to dry. [0003] The pretreatment of polyester-cotton knitted fabrics usually includes desizing, scouring, and bleaching processes. This process takes a long time, has low efficiency, high energy consumption, and a large amount of wastewater. [0004] Therefore, when dyeing and finishing polyester-cotton knitted fabrics, if short-process pretreatment and dyeing processes are adopted, energy, water, and time can be saved. Contents of the invention [0005] In order to overcome the shortcomings of the above-mention...
