Embodiment 1
[0021] In this example, the cellulose pulp is impregnated, squeezed, and pulverized to obtain alkali cellulose with a weight percentage of 28% methyl cellulose and 15% NaOH. After aging and cooling, it is mixed with CS 2 Yellowing reaction produces cellulose xanthate and dissolves in viscose spinning solution made of NaOH, CS 2 The dosage is 30% of methyl cellulose; the deodorant is added during the dissolution process of cellulose sulfonate by NaOH, and then the mixed solution of different batches is mixed again to make the deodorant disperse more evenly, and the viscose spinning after mixing The methyl fiber content in the liquid is 8.15%, the relative methyl fiber content of the deodorant is 3%, and NaOH is 4.5%, (both are weight percentages); the spinning solution enters the coagulation bath through the spinneret, and the coagulation bath composition is Na 2 SO 4 270g / L, H 2 SO 4 98g / L, ZnSO 4 10g / L, coagulation bath temperature 45°C; spinning draft 140%; the drawn tow...
Embodiment 2
[0023] In this example, the cellulose pulp is impregnated, squeezed, and pulverized to obtain alkali cellulose with a weight percentage of 28% methyl cellulose and 15% NaOH. After aging and cooling, it is mixed with CS 2 Yellowing reaction generates cellulose xanthate and dissolves in NaOH to obtain viscose spinning solution;
[0024]The deodorant powder is formed into a uniform dispersion through dispersibility and surfactant, and injected into the viscose spinning solution through the injection tube and two filters before spinning, and the mixed viscose spinning solution is Fiber content 8.15%, deodorant relative methyl fiber content 6%, NaOH 5%, (both percentages by weight);
[0025] The spinning solution enters the coagulation bath through the spinneret, and the coagulation bath Na 2 SO 4 270g / L, H 2 SO 4 98g / L, ZnSO 4 10g / L coagulation bath temperature 45℃; spinning draft 140%;
[0026] Post-treatment, after cutting, washing, desulfurization, bleaching, pickling (hy...
Embodiment 3
[0028] In this example, the cellulose pulp is impregnated, squeezed, and pulverized to obtain alkali cellulose with a weight percentage of 29% of methyl cellulose and 16% of NaOH. After aging and cooling, it is mixed with CS 2 Yellowing reaction produces cellulose xanthate and dissolves in NaOH to obtain viscose spinning solution; while dissolving, mix and stir the deodorant as viscose spinning solution, and the content of methylcellulose in the prepared mixed spinning solution is 8.15% , sodium hydroxide content 5.0%, the addition amount of deodorant is 8.0% of methyl fiber content, and the viscosity of described spinning solution is at 60S; The composition is Na 2 SO 4 280g / L, H 2 SO 4 100g / L, ZnSO 4 11g / L, coagulation bath temperature is 50°C; post-treatment includes cutting, washing, desulfurization, bleaching, pickling, oiling and drying steps, cut into short fibers of 38mm, desulfurization process using sodium sulfite desulfurization (sodium sulfite is 22g / L, desul...
