Abstract

The invention discloses an alginate fiber-containing spunlace fabric capable of absorbing water for gelation, and a preparation method and application of the spunlace fabric. The spunlace fabric is characterized in that the spunlace fabric has an interpenetrating network structure and is composed of 20-30% of sodium alginate fibers and other hydrophilic fibers, wherein the content of the sodium alginate fiber is 20-30%; the spunlace fabric is gelatinized after absorbing water, and the water absorption capacity is greater than or equal to 30g/g; the spunlace non-woven fabric is prepared by adopting continuous production equipment of spunlace non-woven fabric, calcium alginate fibers and other hydrophilic fibers are blended and carded to prepare a fiber net with an interpenetrating network structure at first, then a sodium sulfate aqueous solution is adopted for high-pressure jet flow puncture reinforcement, and finally ultrasonic cleaning and drying are conducted to prepare the spunlacefabric containing the alginate fibers. The preparation method of the spunlace fabric containing the alginate fibers is simple and can be realized on existing industrial equipment with high efficiencyand appropriate in cost, the gelation is generated after water absorbing, and the moisturizing time is more than or equal to 40 minutes, so the spunlace fabric can be used for manufacturing high-grade skin care mask base cloth and high-end medical dressings.

Description

technical field [0001] The invention belongs to the field of textile materials, and in particular relates to a hydroentangled fabric containing seaweed fibers capable of absorbing water and gelling, and a preparation method and application thereof. Background technique [0002] Seaweed fiber is a high-performance fiber material prepared by wet spinning with water-soluble sodium (potassium) alginate extracted from seaweed as the raw material and the aqueous solution of the metal salt as the coagulation bath. Using different metal salt solutions as coagulation baths, the seaweed fibers prepared have certain differences in their chemical structures and properties. Seaweed fibers are a general term for this type of fiber. Commonly used seaweed fibers include calcium alginate fiber, copper alginate fiber, zinc alginate fiber, barium alginate fiber, sodium alginate fiber, etc. These fibers have excellent hygroscopicity, high oxygen permeability, biodegradability, A series of exce...
