Embodiment 1
[0021] Such as figure 1 Shown: a kind of preparation method of apocynum spinnable fiber, comprises former apocynum husk activation treatment process, alkali boiling process, washing process, dehydration drying process:
[0022] The described activation treatment procedure of the former apocynum husk is: under the condition of room temperature, put the former apocynum husk into water, the bath ratio of the former apocynum husk to water is 1:25, then add thiourea to make the thiourea in the water The concentration of hydrogen peroxide in the water reaches 0.08mol / L, the temperature is raised to 65°C, and then 30% hydrogen peroxide and sodium silicate are added to make the concentration of hydrogen peroxide in water 0.25mol / L and the concentration of sodium silicate 0.18g / L. , The holding time is 80 minutes.
[0023] The alkali boiling process is as follows: the solution treated in the activation treatment process of the original apocynum bark is heated up to 75°C, and sodium hy...
Embodiment 2
[0026] A preparation method for spinnable fibers of apocynum, comprising an activation treatment process of the original apocynum husk, an alkali boiling process, a washing process, and a dehydration and drying process:
[0027] The described activation treatment process of the former apocynum husk is as follows: under the condition of room temperature, the former apocynum venetia husk is put into water, the bath ratio of the former venetia apocynum husk to water is 1: 28, then add urotropine to make the water The concentration of urotropine reaches 0.1mol / L, heat up to 70°C, then add potassium permanganate and sodium silicate, so that the concentration of potassium permanganate in water is 0.3mol / L, and the concentration of sodium silicate is 0.2 g / L sodium silicate, the holding time is 85 minutes.
[0028] The alkali boiling process is as follows: the solution treated in the activation treatment process of the original apocynum bark is warmed up to 80° C., adding sodium hydr...
Embodiment 3
[0031] A preparation method for spinnable fibers of apocynum, comprising an activation treatment process of the original apocynum husk, an alkali boiling process, a washing process, and a dehydration and drying process:
[0032] Described former apocynum husk activation process is: under the condition of room temperature, former apocynum husk is put into water, and the bath ratio of former apocynum husk and water is 1: 30, then adds glucose, makes the concentration of glucose in water reach 0.12mol / L, raise the temperature to 75°C, then add potassium persulfate and sodium silicate so that the concentration of potassium persulfate in water is 0.35mol / L, and the concentration of sodium silicate is 0.22g / L. The heat preservation time is 90 minutes.
[0033] The described alkali boiling process is: the solution treated by the original apocynum husk activation treatment process is warmed up to 85°C, and potassium hydroxide, sodium silicate, and sodium tripolyphosphate are added, so...
