Abstract

The invention discloses a method for preparing an apocynum spinnable fiber, which comprises the following processes: activating treatment on an original apocynum skin, soda boiling, washing and dehydration drying. The activating treatment process of the original apocynum skin is as follows: at room temperature, dipping the original apocynum skin in water, adding a reducing agent to the water, raising the temperature to be between 65 and 75 DEG C, adding an oxidant to the mixture, keeping the temperature for at least 80 minutes, and cooling the mixture to the room temperature. Compared with the prior art, the fiber preparation process of the invention has the advantages of simplifying the technical process, greatly reducing the process time, lowering the temperature of a treatment fluid, achieving the aim of saving energy and reducing consumption, and improving the fiber forming rate for the preparation of the apocynum fiber, along with good spinning performance and good handfeel and glossiness.

Description

technical field [0001] The invention belongs to a preparation method of spinnable fiber, in particular to a preparation method of apocynum spinnable fiber. Background technique [0002] Apocynum degumming is an important process in the preparation of apocynum spinnable fibers. The existing degumming research results on apocynum mainly include: chemical degumming process, biological degumming process, and bio-chemical combined degumming process of apocynum. Process problems such as long processing time have a strong impact on the comprehensive performance index of the prepared apocynum fiber, destroying the spinnability of the fiber and the antibacterial and health-care performance of the apocynum. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-temperature short-process preparation method of the spinnable fiber of apocynum. [0004] The technical solution of the present invention to solve the technical pr...
