Embodiment 1

[0031] Embodiment 1 Preparation of bamboo pupa protein fiber filament of the present invention

[0032] a, prepare silkworm chrysalis protein spinning solution, defoaming;

[0033] The preparation method of step a silkworm chrysalis protein spinning solution is as follows:

[0034] (1), get silkworm chrysalis protein 10kg and sodium hydroxide 0.6kg;

[0035] (2), dissolving silkworm chrysalis protein in the sodium hydroxide aqueous solution that temperature is 45 ℃, and concentration is 0.6%w / w, obtains silkworm chrysalis protein solution through filtration;

[0036] (3), get silkworm chrysalis protein solution (wherein containing silkworm chrysalis protein 1kg), 0.08kg of acrylamide by following solid weight, carry out carbamoyl ethylation reaction, filter, obtain silkworm chrysalis protein spinning solution.

[0037] b. Bamboo cellulose is extracted from bamboo;

[0038] It is prepared by chemical and physical methods to remove impurities in bamboo through multiple proces...

Embodiment 2

[0044] The preparation of embodiment 2 bamboo pupa protein fiber short filaments of the present invention

[0045] Steps a to d are the same as in Example 1, and step e is as follows: the fiber tow described in step d is drawn in a bundle, and then enters into plasticizing and stretching, and the cut length is 38-76 mm; It is evenly spread on the fourdrinier wire surface, and as the fourdrinier wire moves forward, hydroformylation, pickling, desulfurization, water washing, oiling and drying are respectively completed in each section to obtain the bamboo fibrin short filaments of the present invention.

Abstract

The present invention belongs to the spinning field and provides a long or short filament of bamboo pupa protein fiber. The long or short filament comprises 10-40wt percent silkworm pupa protein spinning liquid and 60-90wt percent bamboo cellulose viscose as the raw materials. The present invention also provides a method for preparing of the long or short filament. With bamboo cellulose as the raw material, the present invention can still meet the quality standard. Since bamboo cellulose can be acquired easily, the present invention provides a new choice for spinning product-pupa protein fiber.

Description

technical field [0001] The invention relates to long and short filaments of bamboo pupa protein fibers, belonging to the field of textiles. Background technique [0002] Pupa protein viscose fiber is a skin-core composite fiber, its core layer is viscose filament, and the cortex is pupa protein. It is pale yellow in appearance, has a silky soft luster and a smooth feel. The current products are mainly filaments, dyed yarns and strands. The development and application of pupa protein viscose filament not only turns a large number of silkworm chrysalis into treasure after reeling, but also adds a new type of silk-like fabric. [0003] Application number: 97107800.9, name of invention: a method for manufacturing pupa protein viscose filament, the invention relates to a material manufacturing method for the textile industry, and the purpose is to provide a static state using silkworm pupa protein spinning solution and cellulose xanthate solution A method for producing silkwor...
