Fragrant wool fiber and preparation method thereof

Abstract

The invention discloses a fragrant wool fiber and a preparation method thereof. Chitosan and sodium tripolyphosphate are used for coating a damascone spice, nanocapsules with chitosan as an outer shell are formed, then amino of chitosan and amino of a wool fiber are crosslinked through glutaraldehyde, and the nanocapsules coated with the damascone spice are immobilized on the wool fiber by chemical bonds; at the same time, vanillin is directly chemically immobilized on the surface of the wool fiber; and the fragrant wool fiber simultaneously loaded with the vanillin and the damascone spice is prepared. The prepared fragrant wool fiber is simultaneously loaded with the vanillin and the damascone spice, and has vanilla bean aroma of the vanillin spice and strong milk aroma, and fruity flavor, green grass fragrance, flower fragrance, wood fragrance and berry fragrance of the damascene spice; the fragrance is lasting, is slowly released, and is not easy to elute; the obtained wool fiber has the skin friendly performance, and has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of wool fabric processing. More specifically, it relates to a fragrance-containing wool fiber and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people are gradually pursuing high-quality lifestyles, and the requirements for fiber fabrics are getting higher and higher, not only requiring visual and tactile sensations, but also satisfying olfactory sensations. Fragrant fibers have a soothing effect. The development of fragrant fiber has gradually become the development trend of the market to improve mood, reduce stress and stimulate excitement.

Problems solved by technology

Wool fiber is loved by people because of its warmth and comfort, but ordinary wool fiber cannot be removed due to its own odor, so it needs to be treated to make it scented

[0003] The existing fragrance-containing fiber processing method is to directly use emulsified essence to arrange the fiber, but the general emulsified essence is easy to volatilize, the fragrance is emitted quickly, easy to wash off, and the fragrance retention time is not long

Or use ordinary essence microcapsules to finish the fibers, but due to the large particle size of ordinary microcapsules, they can only be attached to the surface of the fibers, and they are easy to fall off under the action of external force, and the fragrance persistence is poor
