Problems solved by technology

At present, most of these antibacterial agents are introduced into polymer materials through coating, blending, chemical cross-linking or block copolymerization, but the molecular weight of these polymers is low, and the combination with the substrate mainly depends on electrostatic adsorption. , hydrogen bond, van der Waals force and hydrophobic interaction and other non-covalent bond forces, so it is not reliable to combine it with materials through coating and blending methods, and there is a problem of antibacterial agent dissolution, which has potential for human health and the environment. Risks, such as cytotoxicity, water pollution, etc.
At the same time, the antibacterial performance of the functionalized fiber or fabric made is difficult to last
However, by chemical cross-linking, redundant cross-linking agents need to be introduced, which not only increases the cost of material preparation but also aggravates environmental pollution.

Embodiment 1

[0041] Embodiment 1, the preparation of elastic fiber PS-GMA / TPU of the present invention

[0042]Put the TPU in an oven at 60°C to dry for later use. Configure a PVA aqueous solution with a mass fraction of 0.2%; configure AIBN, styrene, and GMA with a molar ratio of 1:50:25 into a uniform mixed solution, and then add it to the configured PVA aqueous solution (0.2% by mass fraction) to carry out Reaction: The reaction is pre-polymerized at 85°C for 2h, and then heated to 90°C for 4h. After the reaction is completed, the obtained PS-GMA is filtered, washed several times with ethanol and water, and dried to obtain the PS-GMA polymer. PS-GMA and TPU can be processed by wet spinning (made into a mixed spinning solution, the solvent of the spinning solution is DMF, the mass ratio of PS-GMA and TPU is 1:5, and the solid content of the spinning solution is 30%), dry spinning PS-GMA / TPU fibers were obtained by spinning (PS-GMA, TPU mass ratio 1:5) or melt spinning (prepared into sl...

Embodiment 2

[0043] Embodiment 2, the preparation of elastic fiber PS-GMA / TPU of the present invention

[0044] The preparation method of PS-GMA polymer is the same as embodiment 1, then PS-GMA and TPU are passed through wet spinning (being made into mixed spinning solution, and spinning solution solvent is DMF, and the mass ratio of PS-GMA, TPU is 1 :3, the solid content of the spinning solution is 20%); or by dry spinning (PS-GMA, TPU mass ratio 1:3) or melt spinning (prepared into slices, PS-GMA, TPU mass ratio 1:3 ) and other ways to obtain PS-GMA / TPU fiber.

Embodiment 3

[0045] Embodiment 3, the preparation of elastic fiber PS-GMA / TPU of the present invention

[0046] The preparation method of PS-GMA polymer is the same as embodiment 1, then PS-GMA and TPU are passed through wet spinning (being made into mixed spinning solution, and spinning solution solvent is DMF, and the mass ratio of PS-GMA, TPU is 1 :7, the solid content of the spinning solution is 32%); or by dry spinning (PS-GMA, TPU mass ratio 1:7) or melt spinning (prepared into slices, PS-GMA, TPU mass ratio 1:7 ) and other ways to obtain PS-GMA / TPU fiber.

Abstract

The invention provides an elastic fiber. The elastic fiber contains glycidyl methacrylate grafted polystyrene PS-GMA and polyurethane TPU, wherein the mass ratio of the PS-GMA to the TPU is 1: (3-7); the elastic fiber can be further compounded with an antibacterial agent to obtain an antibacterial elastic fiber; and the elastic fiber has excellent mechanical properties and antibacterial properties, the antibacterial agent is not easy to dissolve out, the safety is high, and the elastic fiber can resist ultraviolet irradiation and washing, can be recycled for multiple times, and has very excellent application prospects in antibacterial textile fabrics.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an elastic fiber and its preparation method and application. Background technique [0002] With the rapid economic and social development and the continuous improvement of living standards in recent years, people's awareness of their own health and environmental protection is also increasing. The requirements for daily-use textiles are not only beautiful and elegant, but also put forward higher requirements for their strength, elasticity and other mechanical properties, as well as health and health care functions. It is important to manufacture textiles with good elasticity and antibacterial properties. It is one of the most effective ways to prolong the service life and reduce the invasion of bacteria, so the textiles with antibacterial function are also more and more favored by people. [0003] The high resilience of polyurethane fiber is unmatched by all elastic ...
