Embodiment 1

[0031] A method for dyeing high-quality polyester raised knitted fabric clothing products, specifically comprising the following steps:

[0032] Step 1, the gray cloth is opened and inspected for the whole cloth. After the gray cloth is unpacked, the process is completed on the opening machine and the cloth inspection machine. Inspection, the open-width finishing of qualified fabrics is placed on the stacking car according to the variety, and the cloth inspection of the gray cloth is completed;

[0033] Step 2: pre-setting the fabric on a sizing machine at a temperature of 180°C for 30 seconds; then remove the oil stains on the fabric through an open-width continuous degreasing machine, and pad in 15g / L degreaser at room temperature , and then steam stacking (100°C, 20 minutes), hot water washing and cold water washing on the cloth in sequence;

[0034] Step 3: Carry out water rolling and vacuum water absorption on the cloth, the excess rate is 30%, the liquid carrying rate o...

Abstract

The invention discloses a method for open-width continuous dyeing of a variety of polyester raised knitted fabrics, which comprises the steps of successively inspecting the gray cloth and inspecting the entire cloth, performing pre-setting processing on the cloth, raising the cloth, and then drying the cloth in a tenter and then packaging the cloth in a package. 1. Pad and dye the cloth, and steam and bake the dyed cloth in sequence. The whole process of the open-width continuous dyeing method of the polyester raised knitted fabric variety is processed in the open-width manner, which can improve the color fastness of the dyed fabric, ensure that the fabric has good elasticity and soft hand feeling, fully exert the inherent characteristics of the knitted fabric, and greatly improve the polyester fabric. The influence of long-car continuous dyeing processing on fabric properties improves production efficiency.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing technology, and in particular relates to a method for continuous open-width dyeing of polyester raised knitted fabrics. Background technique [0002] At present, the dyeing of knitted fabrics in the textile printing and dyeing industry is done intermittently in dyeing vats. The production efficiency is low, the water consumption is large, the sewage discharge is large, and the production cost is high. The Pingfu continuous dyeing process of knitted fabrics has been in the stage of experimental research and development, and has not yet been applied in industrial production. The difficulty in realizing the Pingfu continuous dyeing process of knitted fabrics lies in the color fixation after padding dyeing solution. Bake-fixing and steam-fixing are conventional methods in open-width continuous dyeing of woven fabrics, but it is difficult to realize them in knitted fabrics. The ma...
