Abstract

The invention relates to coffee viscose fiber, which is prepared by crude materials including cotton pulp and coffee residue, wherein the content of the coffee residue accounts for 10 to 30 wt% of cellulose. A preparation method of the coffee viscose fiber comprises the following steps: taking pulp as a crude material for staple fiber production; performing processes including dipping, squeezing, crushing, aging, yellowing, dissolving, defoaming, and filtering so as to obtain a viscose solution; grinding coffee residue into powder and dispersing the powder into an aqueous solution to obtain a slurry; adding the slurry into the viscose solution to obtain a spinning viscose stock solution, wherein the addition amount of the coffee residue accounts for 10 to 30% by weight of the cellulose of the viscose solution; and carrying out spinning and molding on the prepared spinning viscose stock solution in a coagulating bath, and performing processes of drafting, refining, and drying to obtain a finished product of the coffee viscose fiber. According to the invention, the coffee residue, which is distributed evenly in the fiber, is not easy to be lost, so that the antibiotic and odor resistant functions of the coffee residue are lasting. The coffee viscose fiber not only has functions of bacteriostasis, deodorization, and moisture absorption and perspiration, but also has characteristics of moisture absorption and air permeability as well as comfortable wearing property of the viscose fiber. Textiles made from the coffee viscose fibers have a good moisture adsorption performance and a good moisture regain rate as well as have characteristics of comfortable hand feeling and softness and dryness.

Description

technical field [0001] The invention relates to a viscose fiber and a manufacturing method thereof, in particular to a coffee viscose staple fiber and a production process thereof. Background technique [0002] As a drink, coffee has gradually entered the life of modern people and is already a daily drink for many people. Coffee can improve heart function, dilate blood vessels, improve blood circulation, calm headaches, and refresh the mind. Coffee contains certain nutrients such as: vitamin B, free fatty acids, caffeine, tannic acid and so on. Coffee is good for the skin. Coffee can promote metabolism, activate digestive organs, and eliminate fatigue. In terms of health care, coffee has the functions of anti-oxidation and heart protection, strengthening muscles and bones, sharpening waist and knees, appetizing and promoting food, reducing fat and accumulation, benefiting orifices and dehumidification, promoting blood circulation and removing stasis, calming wind and reliev...
