Abstract

The invention discloses a pretreatment method for dyeing a linen fabric by using catalase. The method comprises the steps of (1) immersing a refined and bleached linen fabric into a mixed solution of catalase and a surfactant, heating, soaking, further heating, adding potassium tert-butoxide to adjust the pH and further soaking; (2) soaking the treated linen fabric into a mixed solution of N-hydroxymethyl acrylamide and ZnCl2, carrying out ultrasonic treatment, drying, roasting, washing and drying; (3) dipping the linen fabric processed in the step (2) into a mixed solution of rare earth and an amino acid, carrying out ultrasonic treatment, drying, washing and drying; and (4) dipping the linen fabric treated in the step (3) into a citric acid solution, carrying out ultrasonic treatment, drying, roasting, washing and drying. After the linen fabric is treated by using the method, the dyeing rate of the linen fabric is greatly improved, and the linen fabric is uniform in color and luster and high in color fastness.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a method for pre-dyeing flax fabrics using catalase. Background technique [0002] Linen fabric has good hygroscopic properties, fast heat dissipation, crisp and natural, no static electricity, anti-mildew and insect-resistant properties, and is loved by consumers. Clothing made of linen fabric can reduce the amount of perspiration from the human body more than other fabrics, and the water absorption speed of linen fabric is several times faster than that of cotton fabric. At room temperature, the body's body temperature can be reduced by 4-8 degrees. "Natural Air Conditioning". The flax fiber is a bast fiber, the diameter of the hemp stem is 1-3mm, and the fibers are distributed in the bast part of the stem in bundles. The main component of flax fiber is cellulose, and contains more hemicellulose and lignin. [0003] The dyeing of flax fiber is similar to the dyeing of cott...
