Embodiment 1

[0013] Polystyrene-ethyl acrylate-p-vinylbenzyl trimethacrylate prepared by double-dipping and double-rolling 0.10g / L soap-free emulsion polymerization of polyester / cotton blended fabric (T / C, 65 / 35) at 30°C Hydroxyl ammonium chloride dispersion, the liquid carrying rate is 40%, the pH of the dispersion is 6-7, dried, washed and dried; the treated fabric is dyed by padding with 0.10g / L acid red A dye solution, dried , baked at 120°C for 30 seconds, then washed with water to remove floating color, and dried.

Embodiment 2

[0015] Pad the polyester / cotton blended fabric (T / C, 50 / 50) with 0.10g / L, 0.20g / L, 0.50g / L, 0.75g / L, 1.00g / L, 1.50 g / L polystyrene-butyl acrylate-p-vinylbenzyltrimethylammonium chloride dispersion, with a liquid retention rate of 60%, dried, then washed with water and dried. The treated fabrics were respectively padded with 0.50g / L acid orange II dye solution, the liquid retention rate was 30%, dried, baked at 140°C for 120 seconds, then washed with water to remove floating color, and dried.

Embodiment 3

[0017] Prepare a polystyrene-ethyl acrylate-p-vinylbenzyltrimethylammonium chloride dispersion with a pH of 6-7 and a concentration of 5g / L, and use this dispersion to pad the polyester / cotton blended fabric (T / C , 70 / 30), the liquid-carrying rate was 60%, dried, washed and dried; the treated fabric was padded with 1g / L acid blue R solution, the liquid-carrying rate was 40%, and baked at 140°C for 90 Seconds, then wash to remove floating color and dry.

Abstract

The invention relates to a one-bath one-step dyeing method for a polyester/cotton blended fabric. The polyester/cotton blended fabric is firstly treated by a cationic compound and then is dyed by an anionic dye. The method has excellent dyeing effects on the polyester/cotton blended fabric, is simple in operation and high in efficiency, saves water and energy and reduces waste water emission.

Description

technical field [0001] The invention discloses a one-bath, one-step dyeing method of polyester / cotton blended fabric, relates to a process for realizing one-bath, one-step dyeing of polyester / cotton blended fabric with an anionic dye, and belongs to the field of textile printing and dyeing. Background technique [0002] Polyester / cotton blended fabric not only highlights the style of polyester but also has the advantages of cotton fabric. It has good elasticity and wear resistance under dry and wet conditions, stable size, small shrinkage, straight, not easy to wrinkle, easy to wash, Quick drying feature. Therefore, polyester-cotton blended fabric is a very important textile fabric. The traditional dyeing method of polyester / cotton blended fabric is to dye the two fibers separately with disperse dyes and reactive dyes or other cotton dyes. Therefore, the dyeing process of this type of fabric is long, the operation process is complicated, the energy and water resources are ...
