Embodiment 1

[0056] The preparation method of sorbic acid derivative shown in formula I:

[0057] Add 1mmol sorbic acid into a 50mL round bottom flask, add 2mL DMF at 0°C, and drop 0.14mL triethylamine to obtain liquid A;

[0058] Add 1mmol BOP to another 50mL round bottom flask, add 2mL dichloromethane and 1.15mmol glutathione at 0°C to obtain liquid B;

[0059] Slowly add solution B to solution A at 0°C, stir at 0°C for 30 minutes, then stir at room temperature for 2 hours, follow the reaction by TLC (developing solvent is dichloromethane-methanol=10:1), after the reaction, Dichloromethane was evaporated to dryness, diluted with 15 mL of water, extracted with 30 mL of ethyl acetate, and the ethyl acetate layer was extracted with 1 mol / L HCl to wash away triethylamine in the reaction solution. Wash with saturated aqueous sodium bicarbonate solution to neutralize excess HCl in the previous step. Wash with saturated saline. Then the organic layer was dried over anhydrous magnesium sulfat...

Embodiment 2

[0064] A modification method of above-mentioned bamboo fiber, comprising:

[0065] Step 1: the utilization concentration of bamboo fiber is 5% pretreatment solution (the NaOH of equal concentration and H 2 o 2 Mixed solution) pretreatment 2h, after finishing, rinse bamboo fiber with distilled water until the pH of the washing solution is neutral, and dry to obtain pretreated bamboo fiber;

[0066] Step 2: join pretreatment bamboo fiber and sodium hypophosphite in 8mM sorbic acid derivative solution, the consumption ratio of pretreatment bamboo fiber, sorbic acid derivative and sodium hypophosphite is 1g:100mL:0.15g, sorbic acid derivative The concentration of the solution is as follows: stirring and reacting at 125° C. for 1.5 h, cooling, rinsing the bamboo fiber with distilled water until the pH of the rinsing solution is neutral, and drying to obtain functional bamboo fiber.

Embodiment 3

[0068] A modification method of above-mentioned bamboo fiber, comprising:

[0069] Step 1: the utilization concentration of bamboo fiber is 5% pretreatment solution (the NaOH of equal concentration and H 2 o 2 Mixed solution) pretreatment 2h, after finishing, rinse bamboo fiber with distilled water until the pH of the washing solution is neutral, and dry to obtain pretreated bamboo fiber;

[0070] Step 2: join pretreatment bamboo fiber and sodium hypophosphite in 8mM sorbic acid derivative solution, the consumption ratio of pretreatment bamboo fiber, sorbic acid derivative and sodium hypophosphite is 1g:100mL:0.18g, sorbic acid derivative The concentration of the solution is as follows: stirring and reacting at 125° C. for 1.5 h, cooling, rinsing the bamboo fiber with distilled water until the pH of the rinsing solution is neutral, and drying to obtain functional bamboo fiber.

Abstract

The invention provides a production process of a functional bamboo fiber fabric, and belongs to the technical field of functional fibers. The process comprises the following steps of 1, blending functional bamboo fibers, bamboo fibers and polyester fibers to obtain blended yarns; 2, interweaving the blended yarns to obtain a basic fabric; and 3, cleaning, drying, tentering and shaping the basic fabric to obtain the functional bamboo fiber fabric. According to a modification method of the functional bamboo fibers, a sorbic acid derivative shown in a formula I is used for grafting bamboo pulp fibers to obtain the functional bamboo fibers. The sorbic acid derivative can enhance the antibacterial property, breaking force, breaking strength, breaking elongation and initial modulus of the bamboo fibers; and the phenomenon of end breakage in a weaving process is reduced, the yarn hairiness is reduced, and the pilling resistance and wrinkle resistance of the fabric are improved.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, and in particular relates to a production process of functional bamboo fiber fabrics. Background technique [0002] Bamboo fiber is a new natural fiber developed by people after the appearance of various new natural fibers such as colored cotton and spider silk. Bamboo fiber and its textiles have been successfully developed. Substituting bamboo for wood and bamboo for cotton has found a new fiber raw material with low price and high quality for textiles, opened up a new way for the development and utilization of bamboo resources, and greatly improved the quality of bamboo. Resource-intensive and economical level. The raw material of bamboo fiber is a natural renewable material, and the product after use can be biodegraded. It is a textile material that meets environmental protection requirements with broad prospects. Bamboo fiber is made from bamboo chips into bamboo pulp, and then sp...
