The invention provides a preparation method of a wormwood-stem-based viscose rayon fiber. The preparation method comprises the following steps: (1) preparing wormwood stem pulp by adopting wormwood stem as a raw material; (2) preparing a spinning solution of the wormwood stem pulp by utilizing the wormwood stem pulp; (3) uniformly mixing wormwood-stem-based mucilage glue with common mucilage glue prepared from common cellulose pulp; (4) filtering the mixed mucilage glue, introducing the filtered mixed mucilage glue into a coagulating bath for spinning forming, and then carrying out fiber stretching and aftertreatment to obtain the wormwood-stem-based viscose rayon fiber. Compared with the prior art, the preparation method has the advantages that 1, waste wormwood stem is creatively adopted as the raw material and pollution caused by incineration or irresponsible disposal of wormwood stem can be avoided; 2, the preparation method is easy to implement and has no strict technological requirements; 3, the waste is turned into valuable, so that the antibacterial functional mucilage glue product is prepared.

Deaeration method of cellulose ionic liquid solution for solvent spinning

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.

The invention provides an anti-bacterial, health-caring and skin-beautifying viscose fiber and a preparation method thereof. The viscose fiber includes an anti-bacterial, health-caring and skin-beautifying agent composition including, by weight, 40-50% of apocynum venetum leaves, 30-40% of fructus forsythia and 20-30% of astragalus membranaceus. The preparation method includes the steps of 1) preparing an anti-bacterial, health-caring and skin-beautifying agent solution; 2) preparing a mixture liquid of the anti-bacterial, health-caring and skin-beautifying agent solution and a dispersing agent; 3) preparing the viscose; 4) preparing an anti-bacterial, health-caring and skin-beautifying blended viscose spinning liquid; 5) spinning the anti-bacterial, health-caring and skin-beautifying viscose fiber; and 6) performing after treatment The anti-bacterial, health-caring and skin-beautifying viscose fiber is free of side effect on human body. The fiber is suitable for produce knitted underwear, other clothes and bedding textiles, is wide in available range and has huge economical and social benefit. A blanching process is omitted in the after treatment in the preparation method, so that environment pollution is reduced.

Anti-bacterial, health-caring and skin-beautifying viscose fiber and preparation method thereof

The invention discloses a production method of health fiber and a health fiber produced by the method. The method comprises the following steps of preparing a chitin adhesive and a cellulose adhesive respectively from chitin and cellulose, mixing to obtain a spinning solution, and producing the health fiber by the mixed spinning solution. The health fiber production method of the invention has low requirement for temperature and vacuum degree for alkalization, sulfonation, etc., and is convenient and suitable for industrial production. The health viscose fiber containing chitin as a portion thereof has a plurality of characteristics such as long bacterial resistance, good chromaticity, biocompatibility, bacterial resistance as well as deodorization, and easy degradation.

The invention discloses a preparation technology of cellulose fiber spinning solution. Cellulose pulp is adopted, subjected to alkalization, squeezing, crushing, and cooling to room temperature, mixed with urea aqueous solution, cooled to minus 5 DEG C to 15 DEG C, and stirred till alkali cellulose completely dissolves, and vacuum defoamation is carried out simultaneously in dissolution to prepare the uniform and transparent spinning solution. The solution has good spinning performance.

Preparation technique of cellulose fibre spinning solution

The invention discloses cellulose fibers and a method for producing the same. The method is as follows: firstly, cellulose pulp and ionic liquid are mixed and dissolved according to certain proportion and ionic liquid/fiber spinning stock solution with a cellulose content of between 5 and 25 percent for the mass percent concentration is prepared after deaeration; secondly, the spinning stock solution after deaeration is kept for 2 to 80 hours; strand silk is formed through spinning in air and is driven to enter into spinning bath lotion for washing away the ionic liquid in the strand silk, and then the cellulose fibers are formed. The cellulose fibers adopt green solvent, namely the ionic liquid as solvent and have the advantages of nontoxicity, no volatility and no pollution during the producing process, thereby being favorable for environmental protection and the health of operators; the cellulose fibers are easy to reclaim, thereby realizing cleanliness and green production of the cellulose fibers. Moreover, the performance index of the cellulose fibers produced is superior and the cellulose fibers have the advantages of soft feel, good hydroscopic property and permeability, comfortable wear, good brightness, capability of biodegradation and so on.
