Problems solved by technology

Nowadays, health care fibers and fabrics at home and abroad are achieved by adding agents to surround the surface of fibers in the later stage of fiber or fabric production. However, in the process of wearing and application, with the influence of physical and chemical effects such as wear and washing, its functions gradually decrease. As a result, it will be lost, and the purpose of health care will not be achieved. At the same time, the medicine will also cause certain allergic reactions.

Abstract

The invention relates to a viscose fiber produced by utilizing mint and the process engineering thereof. The process includes: mint preparing, cropping, screening, washing, pre-treating, boiling, desanding and concentrating, chloridizing, alkali refining, bleaching, acid treating, desanding and concentrating, papermaking, dipping, pressing, crushing, maturing, yellowing, rubbing, dissolving, filtrating, debubbling, filtrating, spinning, drafting, severing, post-treating, drying, and packing; in the production process, a relaxative pulp technology is adopted, a preservative agent is added, and an enzyme treatment working procedure is added. The invention utilizes mint as the raw material to produce the viscose fiber, which is a creation of applying mint in the textile industry; and the original special matter of the mint, menthol and menthone, are kept, as well as the characteristics of sterilization, balminess, coolness, environmental protection, mosquito repelling, and so on; so that the fiber products thereof have the natural refreshing healthcare function and create a novel field for the development of the viscose fiber and the functional products thereof.

Description

technical field [0001] The invention relates to a production process of viscose fiber, in particular to a process technology for producing viscose fiber by using peppermint. It belongs to the technical field of textile technology. Background technique [0002] At present, viscose fiber is a regenerated cellulose fiber with a wide range of uses, which is made from natural cellulose such as wood and cotton linters and processed through a series of processes. Because the fiber and fabric have good moisture absorption and release properties, soft hand feeling, comfortable wearing, and close to natural cotton properties, they are favored by consumers. Especially in today's return to nature and green consumption, the demand for fabrics made of natural fibers is increasing day by day. However, with the increasing shortage of traditional raw materials such as wood and cotton linters, the production cost has risen sharply. Therefore, the development and exploration of new raw materi...
