Fluorescent staining method for cotton fiber

Abstract

The invention discloses a fluorescent staining method for a cotton fiber. The method comprises the specific steps of pretreatment, modification, staining and fixation, wherein in the pretreatment step, a cloth sample is pretreated; in the modification step, water is added and then a modifier is added to the pretreated cloth sample to ensure that original negative charge on the surface of the cotton fiber is changed to positive charge, operation is conducted for 5min, temperature is raised to 70 DEG C at 1.5 DEG C per minute and kept for 30min, the cloth sample is taken out of a cylinder and washed with water once, and the modification is finished; in the staining step, water is added and then fluorescent paint for printing is added according to a color formula to the modified cloth sample, operation is conducted for 5min, temperature is raised to 70 DEG C at 1.5 DEG C per minute and kept for 30min, the cloth sample is taken out of the cylinder and washed with the water once, and the staining is finished; and in the fixation step, water is added and then an adhesive is added to the stained cloth sample, temperature rise and heat preservation are conducted, and the cloth sample is taken out of the cylinder, washed with the water cleanly, softened and dried. According to the fluorescent staining method for the cotton fiber, the fluorescent paint for the printing can be used for staining, and the hand feeling, fastness and cloth cover uniformity are improved.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a cotton fiber fluorescent dyeing method. Background technique [0002] As the market demands more and more fabrics with bright fluorescent colors, it is no longer limited to polyester and nylon, and there are also requirements for fluorescent dyeing of natural fibers. But at present, cotton fiber can only get fluorescent effect by printing fluorescent paint on the surface of the fabric. Printing fluorescent color on the surface of cotton fabric with fluorescent paint will cause unacceptable defects such as hard hand feeling, poor fastness, and uneven color of the cloth surface. I want to improve the hand feel. And fastness and cloth can only be dyed with reactive dyes, but the fluorescent dyes for dyeing cotton fibers are currently limited to a small number of colors, and most other colors have not been developed. Contents of the invention [0003] The technical problem main...
