Abstract

The invention relates to a production technology of silkworm pupa protein modified cellulose fibers. The silkworm pupa protein fibers are prepared by mixing a silkworm pupa protein solution obtained by dipping through sodium hydroxide solution with oxidized cellulose fibers and grafting under the condition of heating. According to the production technology disclosed by the invention, protein is enabled to be firmly bonded to cellulose through crosslinking reaction, so that biofibers are modified and are firmly bonded to various animal and plant proteins through grafting, and thus protein composite fibers with the characteristics of natural property, environmental friendliness, skin friendliness, comfortableness and capability of being completely degraded are obtained.

Description

technical field [0001] The invention relates to the field of new textile materials, in particular to a production process of silkworm chrysalis protein modified cellulose fibers. Background technique [0002] Currently on the market, chemical methods are used to extract silkworm chrysalis to obtain protein for spinning, which is then blended with viscose spinning stock solution under certain conditions, and composite fibers are obtained through spinning. [0003] Commonly used methods for hydrolysis of silkworm chrysalis protein powder include alkali-soluble method, acid-soluble method and enzymatic hydrolysis method. The surface of the fiber is activated. By activating the surface groups of the cellulose fibers, the available groups are increased, thereby increasing the grafting rate of fibers and proteins. At present, two methods are used: (1) Selective oxidation of cellulose, mainly to selectively oxidize the secondary hydroxyl group of cellulose to aldehyde group and t...
