Method for dyeing chemical-fiber textile cloth

Abstract

A method for dyeing chemical fiber woven fabrics, belonging to the technical field of dyeing methods, comprising the following steps: Step 1: Mechanically sizing the chemical fiber woven fabrics to be dyed, and placing them in a dye vat for pre-dyeing treatment: Step 2: Putting the chemical fiber woven fabrics in step 1 The obtained processed chemical fiber textile cloth is dyed; step 3: the chemical fiber textile cloth dyed in step 2 is subjected to press dehydration and sizing treatment: the sizing agent is compounded by polyvinyl alcohol and modified starch, and the sizing agent The concentration is 3.0%, and then dried, the moisture content of the dehydrated chemical fiber textile cloth is controlled at 50-60%, the drying temperature is controlled at 90°C-105°C, and the moisture regain is controlled, that is, the colored chemical fiber textile cloth is obtained. Through the study of the dyeing process, the invention can solve the problems of low color uptake and inability to dye medium-dark colors when dyeing chemical fiber woven fabrics and the problem of strong damage to chemical fiber woven fabrics. The invention uses conventional equipment and has the characteristics of simple process, environmental protection, short process and no damage to inherent excellent performance of fibers.

Description

technical field [0001] The invention belongs to the technical field of dyeing methods, in particular to a method for dyeing chemical fiber woven fabrics. Background technique [0002] The traditional dyeing method of carrier and high temperature will seriously damage the fiber strength of chemical fiber textile fabrics, and it is difficult to dye deep, thick and bright colors. Therefore, it is necessary to provide a method for dyeing chemical fiber woven fabrics, which solves the problems of low color uptake and inability to dye medium-dark colors, and the chemical fiber woven fabrics are not damaged. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect and deficiency, and provide a kind of dyeing method of chemical fiber woven cloth. [0004] The technical scheme that the present invention realizes its object adopts is as follows: [0005] A kind of dyeing method of chemical fiber woven cloth, it comprises the foll...
