Problems solved by technology

It can be seen that these two methods are the application of silkworm chrysalis protein in the field of fiber materials, but the functionality and uniformity of the composite fibers prepared by this application method are still limited, and the content of silkworm chrysalis protein attached to the fiber surface is small, and the functionality is limited.
[0003] Lotus cellulose is prepared from lotus plants. Lotus plants are non-cotton plant fiber resources with strong adaptability, low planting costs, and edible, medicinal and ornamental values. However, the development and utilization rate of lotus plants is not high. , its comprehensive utilization value needs to be improved

Abstract

The invention provides silkworm pupa protein / lotus cellulose composite fibers and a preparing method thereof. The preparing method comprises the following steps that firstly, silkworm pupae are degreased, deodorized, dried and ground into silkworm pupa powder, the silkworm pupa powder is subjected to enzymolysis with cellulase, and a silkworm pupa protein solution is obtained; then, lotus stalks are dried, chopped, rubbed and then steeped into an alkaline solution to be boiled, precipitate is taken out, fully washed with water and naturally dried, and lotus cellulose is obtained; then, the lotus cellulose is dissolved in a strong acid solution, fiercely stirred, taken out and subjected to centrifugal washing 3-5 times until liquid supernatant is milk white, the liquid supernatant is regulated to be neutral and subjected to ultrasonic dispersion, and a lotus cellulose crystal whisker suspension is obtained; finally, the silkworm pupa protein solution and the lotus cellulose crystal whisker suspension are mixed and stirred evenly, concentrated and defoamed to form a spinning solution, and the silkworm pupa protein / lotus cellulose composite fibers are obtained with the wet spinning technology.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a silkworm chrysalis protein / lotus cellulose composite fiber and a preparation method thereof. Background technique [0002] Silkworm chrysalis is the main by-product of the silk industry. Silkworm chrysalis has high protein content and contains 18 kinds of amino acids and their biologically active substances. At present, silkworm chrysalis is mainly used as a feed material. People mainly study the separation of various components in silkworm chrysalis to configure various medicines, feed or cosmetic additives, and strive to improve the comprehensive utilization value of silk. In the field of textile materials, silkworm chrysalis protein can also be made into fibers as one of the raw materials to prepare blended fibers. Chinese patent CN103132198B discloses silkworm chrysalis protein fiber and tencel cotton blended yarn and its preparation method. Silkworm ...
