Description
Technical Field
The invention belongs to the technical field of viscose fiber modification, and relates to a preparation method of a plant modified viscose filament yarn.
Background
Viscose (Viscose) is a highly functional textile material belonging to regenerated cellulose fibers, and is a cellulose fiber that is a generic name for Viscose and is obtained by extracting and re-plasticizing fiber molecules from natural wood cellulose using "wood" as a raw material. The fabric is widely applied to the fields of various underwear, textile, clothes, non-woven fabrics and the like. With the development of science and technology, the development of various novel functional viscose fibers becomes a hot point of research.
Patent CN10558955C discloses a nano antibacterial color flame retardant viscose and a manufacturing method thereof, the patent utilizes alkali liquor with alkali content of 10-30g/L to mix and prepare nano silver, sodium sulfite, flame retardant and viscose colorant, and then mixes with spinning solution, but a large amount of inorganic flame retardant particles exist in the form of impurities, which affects spinning spinnability and physical indexes of products.
Chinese patent No. CN107354725B discloses a method for preparing wormwood functional nonwoven fabric, which adopts a technical means of modifying cotton fiber with a modifier AS to achieve the purpose of adding antibacterial effect on cotton fiber, but it is obviously difficult to avoid unnecessary injury due to contact with human skin.
Patent CN201210555849 discloses a functional flame retardant viscose fiber prepared by adding flame retardant through blending on the basis of a high wet modulus viscose fiber production process, which, although the high wet modulus production process makes up for the reduction of fiber strength caused by the addition of a large amount of flame retardant to a certain extent, can not improve the problems of poor bonding between pyrophosphate flame retardant and cellulose and subsequent arrangement loss, and has the disadvantages of complex production process, high production cost and no market competitiveness.
In the aspect of modifying fibers, the surface modification is limited to the use of small molecule surface modifiers such as benzoic acid, stearic acid and the like to perform esterification grafting or silicon oxidation surface treatment on the surface, which has a positive effect on improving the contact surface between the fibers and other functional substances, but the research on improving the dispersion uniformity of other functional substances in the fibers is few, so that the application of the fibers is too single, and the development of various applications of the fibers is needed.
