Embodiment 1

[0027] A pupa protein viscose filament is obtained by static blending, spinning, coagulation, solidification and post-treatment of pupa protein liquid and cellulose sulfonate solution at a weight ratio of 1%:99%. The pupa protein viscose The protein loss rate of the filament during the production process is 10%, and the fiber protein shedding rate of the finished product is 1% after 50 times of washing.

Embodiment 2

[0029] A pupa protein viscose filament is obtained by static blending, spinning, coagulation, solidification and post-treatment of pupa protein liquid and cellulose sulfonate solution at a weight ratio of 40%:60%, and the pupa protein viscose The protein loss rate of the filament during the production process is 23%, and the fiber protein shedding rate of the finished product is 4% after 50 times of washing.

Embodiment 3

[0031] A pupal protein viscose filament is obtained by static blending, spinning, coagulation, solidification and post-treatment of pupa protein liquid and cellulose sulfonate solution at a weight ratio of 20%:80%, and the pupa protein viscose The protein loss rate of the filament during the production process is 15%, and the fiber protein shedding rate of the finished product is 2% after 50 times of washing.

Abstract

The invention relates to a pupal protein-viscose filament and a manufacturing method thereof, which belongs to the field of material in textile industry. The pupal protein-viscose filament is obtained through the following steps: pupal protein essence and cellulose sulphonate solution are processed through static blending, spinning, curdling, solidifying and after-treatment at 1%-60%: 40%-99% by weight percent, the loss rate of protein during the production process of pupal protein-viscose filament is less than 30%, and after finished product is washed with water for 50 times, the expulsion rate of fibrous protein is less than 5%. Formaldehyde is not used during the whole technological process, thereby the influence of formaldehyde on the environment can be eliminated, and the manufactured pupal protein-viscose filament is soft, is golden yellow on color and is good on quality.

Description

technical field [0001] The invention relates to a viscose filament and a manufacturing method thereof, in particular to a silkworm chrysalis protein viscose filament with real silk properties and a manufacturing method thereof, belonging to the material field of the textile industry. [0002] Background technique [0003] The protein content of silkworm chrysalis is more than 50%, which is much higher than that of general food, and the essential amino acids in protein are complete. Silkworm chrysalis protein is composed of 18 kinds of amino acids, of which the content of 8 kinds of amino acids necessary for human body is very high, which is twice that of pork. 4 times that of eggs, 10 times of milk, 8 kinds of essential amino acids are balanced in nutrition, and the ratio is appropriate, in line with the requirements of FAO / WHO (Food and Agriculture Organization of the United Nations and the World Health Organization); silkworm chrysalis also contains potassium, sodium, calc...
