Problems solved by technology

[0003] In the past few years, although the denim laser washing technology has made breakthroughs, the main reason is that the equipment investment cost is high, the laser washing efficiency is low, and the speed is slow, which cannot meet the large-scale process production. Research and development, how to improve the efficiency of denim laser washing technology, enhance the effect of denim laser washing, and at the same time reduce the temperature of laser use, reduce the damage of fabric melting and melting caused by laser, especially for denim fabrics containing spandex and polyester, it is always the denim laser washing technology Technical challenges to be faced and resolved

Abstract

The invention provides an indigo dye laser washing effect enhancer for denim and a preparation method thereof. In the invention, 40-50% of demineralized water is injected into a reaction kettle, and then 5-10% of sodium nitrate and 10-15% of sodium nitrate are added respectively. Magnesium nitrate, 3‑5% aluminum nitrate, after stirring for 15‑25 minutes to fully dissolve; then add 1‑2% aqueous nitrocellulose, 2‑5% sodium polyacrylate, 2‑5% dodecyl Sodium alkylbenzene sulfonate, stirred for 50-70min, after being completely dissolved and mixed evenly, adjust the pH to 2.0-4.0 with 2-5% phosphoric acid. The invention can greatly improve the efficiency of denim laser washing technology, reduce the amount of laser used and the temperature used, the speed can be increased by 2-3 times, reduce the elastic damage of spandex, reduce the damage of fabric melting and melting caused by laser, and comprehensively improve the washing effect. Physical properties of the fabric; whiter base color without yellowing on subsequent soaping.

Description

technical field [0001] The invention relates to the technical field of enhancers, in particular to an indigo dye laser washing effect enhancer for jeans and a preparation method thereof. Background technique [0002] The traditional processing methods of denim clothing are mainly stone washing, sand washing, rinsing, chemical washing, etc. The process is complicated, time-consuming and polluting. In an era of more and more diversification and personalization, this backward processing method obviously cannot adapt to the development of the times. Laser washing can not only easily make traditional effects such as old-fashioned, broken holes, worn-out, and white-washed, but also can customize various washing effects such as cat whiskers, monkeys, sandblasting, and snowflakes, and can also be carved out according to customer needs. Hollow-out pictures and other special patterns, and patterns of different shades and levels can be carved on the fabric of the same color, making th...
