Preparation method of deodorizing far-infrared health-care regenerated cellulose fiber

Abstract

The invention provides a preparation method of a deodorizing far-infrared health-care regenerated cellulose fiber, and the preparation method comprises the following steps: preparing a mixed slurry, preparing a blended spinning solution, spinning, and deodorizing and finishing. According to the deodorizing far-infrared health-care regenerated cellulose fiber prepared by the method, the dry breaking strength is larger than or equal to 2.30 cN / dtex, the wet breaking strength is larger than or equal to 1.1 cN / dtex, the dry breaking elongation is larger than or equal to 18.0%, the 2-nonenal elimination rate is larger than or equal to 90%, the deodorizing far-infrared health-care regenerated cellulose fiber has a remarkable deodorizing function, the far-infrared normal emissivity is larger than or equal to 0.80, and the deodorizing far-infrared health-care regenerated cellulose fiber has the health-care functions of activating cell tissues and promoting blood circulation.

Description

technical field [0001] The invention relates to a regenerated cellulose fiber and a preparation method thereof, in particular to a regenerated cellulose fiber with deodorizing and far-infrared health care functions and a preparation method thereof, belonging to the field of fiber technology. Background technique [0002] With the continuous progress of my country's economy and social civilization, the requirements of the broad masses of the people for life taste and social environment are also increasing. After middle age, body functions begin to decline slowly, and the oxidation rate of the skin will also accelerate. In addition to prone to age spots, the oxidation of the skin will also produce a substance called 2-nonenal. At the same time, there will be the oil secreted on the skin or the smell of some bacteria, which will produce a smell, which is commonly called the smell of the elderly or the smell of the old. Hygiene and health care have become the focus of people's ...

Problems solved by technology

Moreover, the solid substances added are easy to lose without protection treatment, and the functionality and durability of the product cannot be guaranteed.

Invention patent CN103556275B A far-infrared bamboo charcoal viscose fiber and its preparation method. The far-infrared ceramic powder added in this patent technology is composed of metal or metal oxide, which is very prone to sedimentation, and both bamboo charcoal powder and far-infrared ceramic powder are solid , the adsorption capacity of bamboo charcoal is very limited, which seriously affects the physical and mechanical properties and spinnability of fibers, thus affecting the functionality of fibers or fabrics.

[0004] Invention patent CN109943901A discloses deodorizing fiber and its manufacturing method. It is a kind of fiber masterbatch that is added to nylon with zeolite powder and lauric acid. It is melt-spun at a maximum temperature of 280°C, and the lauric acid component is lost at a higher temperature. More seriously, the prepared deodorant fiber has unsatisfactory functionality, and the fiber is a synthetic fiber, and the product is difficult to degrade naturally

However, the spinning and forming process of cellulose fibers is a strong acid system. If the deodorant is directly added to the spinning solution without protection treatment, the loss will be large, and the ideal deodorizing effect cannot be achieved.
