Embodiment 1
[0026] A kind of preparation method of cold wire, is characterized in that, comprises the steps:
[0027] a. Viscose solution preparation
[0028] The pulp is extracted from natural fiber; the pulp is treated with lye and carbon disulfide to obtain cellulose xanthate; the cellulose xanthate is treated in dilute alkali solution to obtain viscose;
[0029] b. Preparation of Easy Cold Viscose Collagen Solution
[0030] After the cold storage agent and the above-mentioned viscose collagen solution are uniformly mixed through a static mixer, the easy-to-cool viscose collagen solution is obtained, and the flow rate at which the cool storage agent enters the static mixer is greater than the flow rate at which the viscose collagen solution enters the static mixer;
[0031] c. Pre-spinning treatment
[0032] At the same time, inject 0.1-0.3% dispersant by weight into the above-mentioned easy cold viscous collagen solution to obtain the final spinning stock solution, and then enter t...
