With the enhancement of environmental awareness of people and the proposal of national energy conservation and emission reduction policies, people pay more attention to the research and development of green environmental protection technologies and environment protection products. Polylactic acid fiber (PLA) is prepared from corn starch and other raw materials by fermenting, converting into lactic acid, polymerizing, and melt spinning. The raw materials are widely available, the product has good biodegradability, and the degradation products are lactic acid, carbon dioxide and water, so that the environment is not polluted, and therefore, the green and environment-friendly polylactic acid fiber is more and more favored by people.
And the polylactic acid yarn has low modulus, soft hand feeling, good drapability, strong luster, good elastic recovery capability and wrinkle resistance, and is suitable for manufacturing various types of garment materials. The polylactic acid fabric has silky luster and comfortable hand feeling, and the skin has good contact feeling and does not irritate the skin; has excellent drapability and good smoothness, and is comfortable to wear; has antibacterial and antiseptic effects, and is beneficial to human health.
However, the existing polylactic acid dyeing usually adopts disperse dyes, but the dyeing rate of the disperse dyes is generally low, so that the polylactic acid fiber fabrics appearing in the market have more light colors and less deep colors, the color vividness is not high, more three primary colors are provided, the color is single, and the color matching products are few so far. The main reason is that when polylactic acid is used for color matching dyeing, dye molecules with different colors have differences in size, structure and the like, so that one dye enters the inside of a fiber when the fiber is dyed easily, and the other dye stays on the surface of the fiber more, and then in the using process, along with the loss of cleaning, friction and the like, the dye on the surface of the polylactic acid fiber falls off quickly, so that the proportion of the dye is changed compared with that during initial dyeing, and finally the color is changed. Therefore, an accelerating agent capable of improving dye uptake and color matching stability is needed to ensure the color matching and dyeing effect of the polylactic acid textile material, so as to solve the problem of single color of the existing polylactic acid textile material.

The dark green polylactic acid fabrics prepared in the examples 1 to 28 were subjected to performance tests, and the results are shown in table 1.
The detection method comprises the following steps: the dry rubbing color fastness and the wet rubbing color fastness are tested by GB/T3920-;
testing the strength loss rate in the warp and weft directions: GB/T3923.1-2013 part 1 of tensile property of textile fabrics: measuring breaking strength and breaking elongation (bar sampling method), testing the breaking strength in the warp and weft directions, and calculating to obtain the loss rate of the strength in the warp and weft directions; wherein, the loss rate of the warp and weft direction strength is (breaking strength before dyeing-breaking strength after dyeing)/breaking strength before dyeing, the loss rate is negative, which means that the strength after dyeing is higher than that before dyeing, if the loss rate is-100%, the strength after dyeing is one time of that before dyeing, and the change of the strength before and after dyeing probably is that the structure of the polylactic acid is changed by the accelerating agent.
Percentage of dye uptake: measuring by using a spectrophotometer; the test method comprises the following steps: firstly, a spectrophotometer is used for measuring the maximum absorption wavelength lambda of a dye solution before dyeingmaxPreparing dye solutions with different concentrations, and measuring the dye solutions at the maximum absorption wavelength lambdamaxDrawing an absorbance-concentration working curve of the dye liquor; then taking the dye solution before and after dyeing, diluting the dye solution by a fixed multiple, testing the absorbance by a spectrophotometer, and obtaining the relative concentration C after dyeing according to an absorbance-concentration working curve of the dye solution, wherein the dye uptake rate is 100% -relative concentration C; wherein, the dilution multiple adopted by the invention is 25 times.
