Embodiment 1

[0020] First, prepare the material. When preparing the material, you can use a mechanical method to obtain the bast of S. japonica. For example, use a peeling machine and other mechanical methods to remove the epidermis of S. japonicus to obtain the bast of S. japonicus, and screen the bast of S. japonicus. , in order to select the bast that meets the production needs, and then perform preparatory work such as cutting, cleaning, and impurity removal, and then cook according to the process. According to production requirements, the boiled mulberry bast can be beaten in a beating machine, and sand removal can be carried out in a desander to remove impurities and fine fibers in the pulp; the obtained pulp will be bleached, if applicable Sodium hypochlorite, after bleaching, the residual liquid is drained and washed, de-sanded, concentrated and pulped to obtain pulp for the production of mulberry viscose filaments, and then the obtained mulberry pulp is impregnated, Squeeze and pu...

Embodiment 2

[0031] The process steps and raw materials of the present example are the same as those in Example 1, except that they are in production

[0032] Cooking NaOH is 15% relative to the absolute dry material amount, the liquid ratio is 1:3, the temperature is raised to 160 ° C within 120 minutes, and the temperature is kept for 200 minutes;

[0033] Bleaching uses two-stage bleaching:

[0034] The first stage of bleaching: PH value 4, the amount of chlorine used is 0.6% of the effective chlorine amount relative to the absolute dry material amount, and the time is 10 minutes;

[0035]The second stage of bleaching: PH value 11, the amount of chlorine used is 3% of the amount of effective chlorine relative to the amount of absolute dry material, the temperature is 40°C, and the time is 90 minutes;

[0036] The impregnation temperature is 60°C, the concentration of lye is 200g / l, the content of methyl fiber is 29.8%, and the content of alkali is 14.9%;

[0037] The amount of carbon ...

Embodiment 3

[0041] The process steps and raw materials of this embodiment are the same as those in Example 1, only in production

[0042] Cooking NaOH relative to absolute dry material amount is 18.5%, liquid ratio is 1:3.5, the temperature is raised to 165°C within 80 minutes, and the temperature is kept for 180 minutes;

[0043] Bleaching uses two stages of bleaching:

[0044] The first stage of bleaching: PH value 3, the amount of chlorine used is 0.4% of the amount of available chlorine relative to the amount of absolute dry material, and the time is 20 minutes;

[0045] The second stage of bleaching: PH value 10, the amount of chlorine used is 2% of the amount of effective chlorine relative to the amount of absolute dry material, the temperature is 35 ° C, and the time is 135 minutes;

[0046] The impregnation temperature is 55°C, the concentration of lye is 240g / l, the content of methyl fiber is 24.3%, and the content of alkali is 19.4%;

[0047] The amount of carbon disulfide add...

Abstract

The invention discloses a viscose filament and its process for preparing, and the producing step mainly includes feed preparation, boiling, materials-washing, beating, riffling, bleaching, rinshing, riffling, compression, lifting, paste-dipping, pressing, comminuting, aging, etiolation, dissolution, mixing, filtration, debubbling, filtering, spinning, degumming, drying, conditioning, canister forming and grading. The invention provides a new raw material and manufacturing technique for the viscose filament production, and the viscose filament prepared by the invention is of good white content, high breaking strength, and few disadvantage and can well fit the requirement of practical production.

Description

technical field [0001] The invention relates to a technology for producing viscose filaments in the field of textiles, in particular to a mulberry mulberry viscose filament produced by using the mulberry bast as a raw material and a preparation method thereof. Background technique [0002] At present, in the textile industry, chemical fibers have become the most widely used textile raw materials, and the development and use of chemical fibers are increasing day by day. According to statistics, the production and use of chemical fibers in the world have accounted for 50% of the total textile fibers. % and is still growing. Among them, viscose filaments account for a considerable proportion in chemical fibers. Because the cellulose content of cotton linters is relatively high, it is easy to manufacture high-purity cotton pulp, so most manufacturers currently use cotton pulp as raw material to produce viscose filaments. However, due to the serious shortage of cotton raw mater...
