Problems solved by technology

However, in the process of wearing and application, with the influence of physical and chemical effects such as wear and washing, its function will gradually decline and even be lost, and the real antibacterial purpose cannot be achieved. At the same time, the added medicament will also cause certain allergic reactions, thus May affect the wearer's skin and make it uncomfortable to wear

Abstract

The invention involves a method to produce mucilage glue long-thread by using hemp plasm. It contains: plasm dipping, squeezing, crushing, full growth, etiolation, after-dissolving blending, filtering, baking, becoming canister, twisting, and packing. The source of the material is abundant and the production feels silken and seems colorful. It can replace natural silk and provides an approach of using hemp properly. At the same time, it remians the natural hemp of crude anti-bacterium, and empolder a a new applied realm of mucilage glue long-thread.

Description

technical field [0001] The invention relates to the production of viscose filaments from hemp pulp and its technology. technical background [0002] As a kind of textile raw material, viscose filament is traditionally produced using cotton linters and wood as raw materials and processed through a series of technological methods to obtain regenerated cellulose fibers. The fiber and its fabric have the characteristics of easy dyeing, light and thin texture, smoothness and softness, and are mainly used to make clothing, bedding and decorations, etc., and are very popular among consumers. However, with the reduction of cotton planting area, the country has implemented more and more strict forest protection policies, and there has been a shortage of cotton linters and wood for the production of viscose filaments, which has led to price increases and a sharp increase in production costs. Research and development of new Natural raw materials are imperative; at the same time, from ...
