Problems solved by technology

However, at present, the international and domestic textile industries basically apply it to simple knitwear such as underwear, round-neck shirts, T-shirts, socks, etc., and there are few studies on clothing fabrics with complex structures containing coffee carbon, especially those containing coffee. Carbon fiber fabrics have many problems such as low dyeing rate, scratches, fuzzing, and poor color fastness, which limit their application in the textile field.

Embodiment approach

[0031]In one embodiment of the present invention, the viscosity-average molecular weight of poly-L-lactic acid is 45-350kDa, wherein the molar content of L optical isomer is 97.5-99.9%; the viscosity-average molecular weight of poly-D-lactic acid is 15-80kDa, wherein D The molar content of optical isomers is 97.5-99.9%. Preferably, the viscosity-average molecular weight of PLLA is 80-230 kDa, and the viscosity-average molecular weight of PDLA is 45-65 kDa. More preferably, the viscosity-average molecular weight of PLLA is 100-180 kDa, and the viscosity-average molecular weight of PDLA is 50-60 kDa. The addition of poly-D-lactic acid can make the left-handed and right-handed structures complementary, make the molecular chains tightly packed, strengthen the intermolecular force, improve the heat resistance and high-temperature stability of poly-lactic acid, and avoid high-temperature drying or spinning. The hydrolysis reaction and degradation reaction of polylactic acid further...

The viscosity average of the above-mentioned PLLA The molecular weight is 130kDa, wherein the molar content of L optical isomer is 98.9%, the viscosity average molecular weight of PDLA is 55kDa, wherein the molar content of D optical isomer is 99.1%;

[0053] (2) Add 0.15 parts by weight of plasticizer to 68 parts by weight of polylactic acid slices, stir evenly and pulverize into powder, then add 18 parts by weight of coffee carbon nano powder and 0.5 parts by weight of antioxidant 1010 After mixing evenly, melt and granulate at 170-250°C to obtain coffee carbon polylactic acid masterbatch. The above-mentioned toughening agent is...

Embodiment 2

[0056] A method for making a PLA fiber fabric containing coffee carbon, the concrete steps are as follows:

[0057] (1) Spinning: get the fiber spinning made in Example 1, the yarn is the twisted silk of PLA fiber containing coffee carbon, and its specification is 100D / 45F-180D / 75F;

[0058] (2) Pre-treatment: Put the yarn in the dyeing tank, enter water, first add the penetrant sodium alkyl succinate sulfonate in an amount of 0.15g / L, react for 30min, and then use 5g / L and 6.5g respectively Add soda ash and sodium silicate in an amount of / L, then raise the temperature to 75°C, add hydrogen peroxide in an amount of 5g / L and keep it warm for 10 minutes, then raise the temperature to 90°C, keep it warm for 35 minutes, cool down, and wash with water;

[0059] (3) Dyeing: enter water according to the bath ratio of 1:33, then add leveling agent triethanolamine, dyes and salt at 40°C, raise the temperature to 105°C at a heating rate of 1.5°C / min, keep it warm for 45min, add soda as...

Abstract

The invention provides a manufacturing method of a coffee carbon containing PLA fiber fabric and belongs to the technical field of textile, including the steps of spinning, pre-treating, dyeing, weaving, finishing and sizing. Raw fibers for spinning are prepared by the steps of providing polylactic acid chips comprising poly-L-lactic acid and poly-D-lactic acid and coffee carbon polylactic acid master batch comprising flexibilizers and antioxidants, melting and spinning the master batch and the polylactic acid chips, performing hot drafting and hot setting to obtain the coffee-carbon-containing PLA fiber fabric. According to the manufacturing method, heat resistance and high temperature resistance of the fibers can be improved, tensile strength and elongation at break can be enhanced, andresilience and crease resistance performance of fibers and fabric can be improved by increasing crease recovery angle, further, dye-uptake and dyeing rate of the fibers can be increased, color fastness to dyeing and washing is improved, color persistence and shape preservation of the fibers and fabric are also can be promoted, time for dyeing can be shortened, production cost and energy consumption can be reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for making a PLA fiber fabric containing coffee carbon. Background technique [0002] With the improvement of people's living standards and the acceleration of work rhythm, the requirements for the protective function of clothing are getting higher and higher. The textile industry's attention to green and environmentally friendly products has gradually become the standard for new product development. Textiles with a single function can no longer meet people's needs, and textiles with multi-functional finishing are getting more and more attention and love because of their excellent performance. . [0003] Polylactic acid fiber (PLA fiber) is made from lactic acid fermented from renewable natural substances such as corn, potato, and sugar beet, and then polymerized and spun. It is fully biodegradable and recyclable. Polylactic acid fabric also has excellent...
