Abstract

The invention provides a full-effect refining agent for regenerated mulberry fiber and a use method of the full-effect refining agent. The full-effect refining agent comprises bio-enzyme, mulberry nano-crystalline cellulose and aids. The use method comprises the following steps: beating fresh mulberry, removing dust, performing acid-alkali pretreatment, and performing boiling treatment with a solution of neutral cellulase and pectinase so as to obtain pretreated mulberry fiber; performing aeration treatment on pretreated mulberry fiber so as to obtain long mulberry fiber and short mulberry fiber, and combing and kneading the long mulberry fiber so as to obtain primary spinning mulberry fiber; performing reaction on the short mulberry fiber in an inorganic acid solution, performing centrifugal separation, and performing filtration and washing so as to obtain mulberry nano-crystalline cellulose; treating the primary spinning mulberry fiber with peregal O and vinyl triethoxy silane, further adding into the mulberry nano-crystalline cellulose, dropping ammonia water, and performing vacuum drying, thereby obtaining the regenerated mulberry fiber. The regenerated mulberry fiber prepared with the agent is soft in hand feeling, good in mechanical property and good in properties such as thermal resistance and flame retardancy.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a full-effect refining agent for regenerated mulberry fiber and its application method. Background technique [0002] Mulberry fiber comes from the bast part of mulberry branches and belongs to bundle fiber. Mulberry bast is composed of about 30% cellulose and about 70% colloid. Among the colloids, pectin accounts for 26.37%, lignin accounts for 7.04%, and the content of lignin in mulberry fiber is only 7%. The fiber with less content has good luster, softness and elasticity. Therefore, the luster, softness, elasticity and spinnability of mulberry fiber are good, and it is another typical green textile after bamboo fiber. [0003] The length of the mulberry fiber is between 5 and 15mm. The length of the mulberry single fiber is relatively short and cannot be directly used for spinning. The cross section of the mulberry fiber is elliptical or polygonal and h...
