Problems solved by technology

However, the color fastness to washing and the color fastness to light decreased to varying degrees
[0011] However, the above-mentioned prior art can only dye light colors or medium colors, and it is difficult to dye dark colors, especially not easy to obtain black or navy blue, and the color fastness, especially the color fastness to washing and wet rubbing, is not ideal enough

Embodiment 1

[0073] 35wt% C.I. Disperse Blue 27, 30wt% C.I. Disperse Orange 30 and 10wt% C.I. Disperse Red 343 and the rest of the nonionic dispersant AEO-9 were mixed and ground with water to obtain a disperse black dye composition slurry. According to the mass ratio of 1:10, dodecyl dimethyl benzyl ammonium chloride and n-pentyl acetate are mixed, and emulsified in the presence of an appropriate amount of water to obtain a dyeing auxiliary. Then, according to the consumption of the disperse black dye composition is 5% (owf); the consumption of the dyeing auxiliaries is 5.8g / L to prepare the dye bath, and the pH value of the dye bath is adjusted to 5.0. Add the desizing-treated PLA / PHBV fiber fabric to the dyeing bath, and heat up at a rate of 2°C / min; keep warm after reaching 115°C, and dye for 40 minutes; cool down after dyeing, restore to clean, wash and dry; restore to use for cleaning The solution is sodium carbonate 2g / L; hydrosulfite 2g / L; reduction cleaning conditions are: tempera...

Abstract

The invention discloses a dyeing composition of PLA / PHBV fiber fabric, which comprises a disperse black dye composition and a dyeing auxiliary; wherein, the disperse black dye composition comprises a disperse blue dye monomer, a disperse orange dye monomer and a disperse red dye monomer. The composition can dye dark colors to obtain black PLA / PHBV dyed fiber fabrics; the color fastness, especially the color fastness to washing and wet rubbing is improved.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and relates to a dyeing composition of PLA / PHBV fiber fabrics. Background technique [0002] In recent years, with the improvement of the level of economic development, people's requirements for textiles no longer meet the basic requirements of warmth and comfort, but hope that textiles have new additional functions, such as antibacterial, deodorant, anti-mite, negative ions, anti-ultraviolet, Radiation protection, far infrared, flame retardant, water and oil repellency and fragrance and other health care and safety functions. Among them, biomass textiles are an important class of textiles. While meeting the low-carbon economy and sustainable development regulation, they can also meet people's needs for fabric diversity and functionality, and can also meet the requirements of various industries. [0003] According to different sources of raw materials, biomass textiles can be divided...
