Slub dyeing technique for bamboo charcoal modified polyester fibre

Abstract

The invention relates to a dye method of bamboo charcoal modified polyester fiber, which uses Ascracen disperse cation dye produced by German Desda Fabric Dye Company. And the method comprises that coming bamboo charcoal modified polyester fiber to be arranged in high-temperature drying machine to operate for 3-5min at 30-40Deg. C, adding 0.3-0.5g/L glacial acetic acid and 2.5-4g/L glauber salt to operate for 5-10min, adding dye to operate for 5-10min, increasing temperature at 1-2Deg. C/min, stopping increasing temperature when the temperature is 80+-2Deg. C, and holding temperature for 10-15min, increasing temperature to 100-115Deg. C at 0.75-1Deg. C/min, to operate for 40-60min, discharging liquid and washing, then arranging the dyed bamboo charcoal modified polyester fiber into soap detergent, to process for 20-30min at 80-90Deg. C. The invention can be used dye bamboo charcoal modified polyester fiber, with better dye effect, high color stability and no hurt on copper ammonia fiber in the dye process.

Description

technical field [0001] The invention relates to a dye selection for bamboo charcoal modified polyester fiber dyeing, and a dyeing and post-treatment process corresponding to dyeing with dyes in top dyeing. It belongs to the technical field of fiber dyeing. Background technique [0002] In the era of rapid advancement of modern science and technology, technology has brought more and more benefits to people's lives. People are yearning for the health and comfort of returning to nature, and many new fibers have emerged. The bamboo charcoal polyester fiber that has appeared in recent years is one of them. one. [0003] Bamboo charcoal modified polyester fiber refers to the polyester fiber with multi-porous structure made by blending bamboo charcoal ultrafine particles and polyester, and has special functions such as super adsorption, antistatic, antibacterial, mildew proof, and negative ion emission. . The production process is as follows: Bamboo charcoal is made by firing ba...

Problems solved by technology

[0005] Compared with conventional polyester, bamboo charcoal polyester fiber has different physical and chemical properties. Hydrophilic anionic groups are added to the molecular structure of bamboo charcoal polyester fiber, but not sulfonic acid groups. The affinity of the fiber is reduced, the solubility in the fiber is also reduced, and the degree of binding to the fiber is also weakened. Due to the addition of bamboo charcoal powder, the pores of the fiber are increased, and the fiber has a honeycomb hollow structure, and dyes that are weakly combined with the fiber are easy Therefore, after dyeing with disperse dyes, the color fastness is very poor. After reduction cleaning, most of the dyes are washed out, and the color requirements cannot be met at all.
