Abstract

The invention relates to the field of a finishing method of cotton knitted goods and discloses a finishing method for improving the shrinkage rate of napped lints of the cotton knitted goods and the quality of plush. The finishing method comprises the following steps: (1) dyeing grey cloth, dewatering and arranging the cloth; (2) sizing and drying a pulling needle; (3) napping and raising; (4) tentering and sizing; (5) fully overfeeding and tentering for sizing; (6) carrying out flat-screen loose type drying; and (7) adding steam to pre-shrink a felt for sizing. The finishing method disclosed by the invention has the advantages that the prior art is improved, the traditional steps of washing and drying are omitted, the steps of fully overfeeding and tentering for sizing and carrying out flat-screen loose type drying are added for alternation, and the technical problems of high shrinkage rate of finished products and low quality of the plush in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of cotton knitwear finishing methods, in particular to a finishing method for improving the shrinkage rate and plush quality of cotton knitwear brushed fleece. Background technique [0002] Cotton knit gray fabric sample dyeing and finishing processing, the general gray fabric is 340 grams of 80 / 20 cotton polyester plush fabric, and the customer provides a plush fabric sample. , The internal quality index requires that the ring drying shrinkage rate be controlled within plus or minus 5%. [0003] The conventional finishing method is to send enough overfeed stenter to set the shape after the plush cloth needle is shaped and dried, and then the finished product is shaped by steam pre-shrinking woolen blanket. Although the surface of the cotton is flat, crisp and clean in this finishing method, and the velvet is thick and dense like wool, but because the velvet cloth is raised mechanically on the napping machine and the...
