Viscose fiber for eliminating bad smell of perspiration and preparation method thereof

Abstract

The invention belongs to the technical field of preparation of fibers, and relates to a functional viscose fiber for producing silicate minerals and acid and salt amphoteric matters, in particular to a viscose fiber containing an adhesive short fiber and an adhesive filament for eliminating bad smell of perspiration and a preparation method thereof. The viscose fiber for eliminating bad smell of perspiration comprises a chitin fiber and a deodorant, wherein the weight percentage content of the chitin fiber is 92.5-98 percent; the deodorant is an aluminum silicate mineral inorganic deodorant, and is less than or equal to 1 mum in average particle diameter; the chitin fiber or cellulose comprises an adhesive short fiber and an adhesive filament; the dry fracture strength of the adhesive short fiber is more than 2.23cN / dtex, and the wet strength is more than 1.05cN / dtex; the dry fracture strength of the adhesive filament is more than 1.7cn / dtex, and the wet strength is more than 0.84cn / dtex; and the ammonia gas reducing rate can be more than or equal to 75 percent, the acetic acid reducing rate can be more than or equal to 80 percent, and the isopentanoic acid reducing rate is more than or equal to 85 percent. The preparation method comprises the following steps of: mixing a nano-grade deodorant with a high-concentration cellulose adhesive to obtain a blended spinning solution; spinning and molding a blend fiber through a coagulation bath; and desulfurizing, washing with water and drying to obtain the viscose fiber for eliminating bad smell of perspiration. A product has the advantages of high deodorizing performance, no side effects, simple preparation process, reliable principle, easiness and convenience in operating, saving in energy sources, environment friendliness and remarkable economic benefit.

Description

Technical field: [0001] The invention belongs to the technical field of fiber preparation, and relates to a functional viscose fiber produced from silicate minerals and acid and salt amphoteric substances, in particular to a sweat-absorbing and smelly viscose fiber containing viscose staple fibers and viscose filaments and its The preparation method, the fiber can be antibacterial and deodorizing, eliminate ammonia gas, acetic acid and isovaleric acid and odors and odors generated by human body sweating, and is suitable for textile, clothing, medical and other occasions. Background technique: [0002] With the gradual improvement of people's living standards and awareness of health and environmental protection, various types of functional fibers and fabrics have emerged in recent years, including flame-retardant, antibacterial, far-infrared, and phase-change energy storage functions. Nowadays, consumers Higher requirements are put forward for the functions of textiles such a...

Problems solved by technology

At present, it is common to use a strong aromatic substance to cover up the odor or mix it with a neutralizer so that people do not feel the odor; or use the adsorption of bamboo charcoal to absorb the odor. In terms of functional fibers, this is useful. The principle of making bamboo charcoal fiber is introduced, but the color of the prepared fiber is black or gray, which is not conducive to post-processing such as dyeing, and the elimination of odor is mainly due to odor and unsaturated compounds with large molecular diameters, such as benzene, mercaptan, etc. , the type of absorption is limited, and it cannot play a role in sweat odor

At present, deodorant fabrics on the market are mainly processed through post-finishing, that is, deodorant materials with different principles are made into deodorant finishing agents. Functional components react or adsorb on the surface of the fiber; although the deodorizing effect can be achieved through post-finishing processing methods, since the auxiliary agent only stays on the surface of the fabric, it may be removed after repeated washing, so there are certain limitations

If the fibers or yarns are directly impregnated and deodorized, the adsorption capacity of the woven fabrics to the deodorizing components will be greatly increased, and the washing resistance of the fabrics will be greatly improved. After the thread is treated, it will have a great impact on its dyeing, finishing and other processes. At the same time, the washing or other chemical treatments in the subsequent treatment process may also have an impact on the deodorizing effect.
