Abstract

The invention relates to an antigenic fibrillated cellulose fiber and a preparation method thereof. The preparation method comprises the following steps: extruding, coagulating, stretching and washing a cellulose fiber spinning solution through a spinneret to obtain washed silk, The water-washed silk is treated with an aqueous linking agent and then rinsed and dried to obtain antigenic fibrillated cellulose fibers; the temperature of the washing is ≥90 °C, the temperature of the aqueous cross-linking agent during the treatment is 65-90 °C, and the temperature of the rinsing is 20-20 °C. 40° C.; the crosslinking agent contains one or more of a group capable of forming a covalent bond with a cellulose hydroxyl group, a group capable of self-crosslinking reaction, and a group capable of forming a hydrogen bond with a cellulose hydroxyl group. The prepared antigenic fibrillated cellulose fiber is mainly composed of a cellulose fiber matrix and a cross-linking agent dispersed in the cellulose fiber matrix. The preparation method of the invention has simple process and mild conditions; the prepared fiber has excellent mechanical properties and excellent water-washing resistance.

Description

Technical field [0001] The present invention belongs to the field of fiber manufacturing techniques, and involves an antigenic cellulose fiber and a preparation method thereof. Background technique [0002] Cotton in cellulose fibers, hemp fiber has good warm properties due to its products, long-term textile raw materials. Because of its advantages of renewable, non-toxic, making fabric comfort, hygienic health, waste of waste, and white pollution, which is the most important raw material for textiles for a long time, with the development of society, although Polyester fibers replace their role to a certain extent, but it is still mainstream of textiles. However, with the continuous development of the market, the demand for cellulose fibers is increasing. Natural cellulose fibers such as cotton, limited yields are limited, and it is difficult to meet the growing consumer demand, so people have developed artificial cellulose fiber (regenerated cellulose fiber). ), It is mainly usi...
