preparation example Construction

[0046] The embodiment of the present application provides a preparation method of seaweed fiber, comprising:

[0047] S10. Using raw materials including sodium alginate to prepare spinning solution;

[0048] S20. Extruding the spinning solution obtained in S10 to a coagulation bath for coagulation and molding to obtain primary fibers;

[0049] S30. stretching and washing the primary fibers obtained in S20 to obtain seaweed fibers;

[0050] S40. Immersing the seaweed fibers obtained in S30 into a treatment agent for post-treatment;

[0051] Wherein, at least one or all three of the raw material in S10, the coagulation bath in S20 and the treatment agent in S30 include a five-membered ring quaternary ammonium salt polymer.

[0052] In the above-mentioned embodiments, the seaweed fibers of the embodiments of the present application can be used to prepare seaweed fiber blended fabrics, and the seaweed fiber blended fabrics are blended fabrics of seaweed fibers and one or more othe...

Embodiment 1

[0105] (1) 40 g of sodium alginate and 1 g of five-membered ring quaternary ammonium salt polymer modifier were formulated into 1000 g of a solution.

[0106] (2) prepare the five-membered ring quaternary ammonium salt polymer modifier solution coagulation bath of the calcium chloride+1% of mass percent 5%, and regulate the coagulation bath pH value to 5 with hydrochloric acid, after the spinning solution is left standing for degassing Extruded into a coagulation bath aqueous solution at 40°C for coagulation and molding, and then stretched and rinsed.

[0107] (3) Dissolve 1g of the five-membered ring quaternary ammonium salt polymer modifier in water to form 1000g of soaking solution; contact the seaweed fiber prepared in step (2) with the soaking solution at 30°C for 20 minutes, and the soaking is completed After washing and drying, post-treatment cross-linked seaweed fibers are obtained.

Embodiment 2

[0109] (1) Dissolve 100g of sodium alginate in water to make a 2000g solution.

[0110] (2) prepare the five-membered ring quaternary ammonium salt polymer modifier solution coagulation bath of the calcium chloride+1.5% of mass percent 6%, and regulate the coagulation bath pH value to 6 with hydrochloric acid, after the spinning solution is left standing for degassing Extruded into a coagulation bath aqueous solution at 40°C for coagulation and molding, after drawing and washing;

[0111] (3) Dissolve 6g of the five-membered ring quaternary ammonium salt polymer modifier in water to form 1000g of soaking solution; contact the seaweed fiber prepared in step (2) with the soaking solution at 40°C and soak for 10 minutes, and the soaking is completed After washing and drying, post-treatment cross-linked seaweed fibers are obtained.

Abstract

The invention discloses alginate fiber and a preparation method thereof, and belongs to the technical field of textile fabric dyeing. The preparation method of the alginate fiber comprises the following steps of S10, preparing a spinning solution from a raw material containing sodium alginate; S20, extruding the spinning solution obtained in the step S10 into a coagulating bath for coagulating and forming, so that primary fiber is obtained; S30, drafting and washing the primary fiber obtained in the step S20 to obtain the alginate fiber; and S40, immersing the alginate fiber obtained in the step S30 into a treating agent, and carrying out post-treatment, wherein at least one or all of the raw material in the step S10, the coagulating bath in the step S20 and the treating agent in the step S30 comprises or comprise a five-membered ring quaternary ammonium salt polymer. The alginate fiber obtained through the method is relatively high in dye-uptake rate, small in fiber strength damage and relatively high in soaping fastness.

Description

technical field [0001] The application belongs to the technical field of textile fabric dyeing, and in particular relates to a seaweed fiber and a preparation method thereof. Background technique [0002] Seaweed fiber is a new type of green biodegradable fiber made from sodium alginate extracted from natural seaweed through wet spinning process. It has been valued for its excellent hygroscopic properties, film-forming and fiber-forming properties, as well as good biodegradability and biocompatibility. [0003] Seaweed fiber has been widely used in the field of medical dressings, and it also has great potential in high-end clothing, underwear fabrics and decorative textiles. [0004] The smooth feel of seaweed fiber brings wearing comfort, but also brings difficulty in spinning. On the one hand, it is still difficult to realize purely spun seaweed fiber yarns in the related art. On the other hand, because the current price of seaweed fiber is still slightly higher, so the...
