Abstract

The invention discloses a preparation method for cold silks. The preparation method comprises the following steps: preparing a mucilage glue stock solution; preparing a cold mucilage glue stock solution and adding a cold storage agent; treating before spinning and injecting dispersing agent; spinning, weaving and thus obtaining the final cold silks. According to the method, the physical mixing mode of adding auxiliaries is adopted, so that the chemical structure of the viscose is not changed and the effect of the frozen silk in the market is achieved; the technique is simple; the main production technique of the current conventional viscose is not changed; the pipeline mixing and injection method is adopted, so that the preparation of the easily cooling mucilage glue stock solution is realized and the investment is less; the productivity is high; the cold silk product can increase the living quality of people and also can meet the market requirement.

Description

technical field [0001] The invention relates to a method for preparing viscose filaments, more specifically, the invention relates to a method for preparing cold filaments, which belongs to the production and manufacture of easy-to-cold viscose filaments. Background technique [0002] Cold silk is a new product of viscose filament, which belongs to ecological fiber, which comes from nature and is superior to nature. Because the moisture content of cold silk is most in line with the physiological requirements of human skin, it has a wide range of applications, such as making fabrics, catgut, facial masks and other products. The fabrics are smooth, cool, breathable, antistatic, comfortable, Health care and other effects, there is a good market application prospects. Cold storage agent is a translucent (or opaque), viscous jelly-like mixture composed of organic or (and) inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures, and can r...
