The reporter learned from the Yibin Silkia Group on the 16th that a "ultra-imitation cotton" fiber raw material based on bio-based and biomass materials was successfully developed by the company. Compared with natural cotton, its strength is increased by 15% to 20%, its boiling water shrinkage rate is the smallest in its peer group, and its appearance gloss, chromatogram, function and fineness are better. It is expected to reduce the cost of the textile industry and energy consumption of resources and become a raw material of cotton fiber. "New substitute".
This new type of fiber material, dubbed â€œYaiseâ€, uses 100% cellulose fiber as the bio-based and biomass material, and possesses many characteristics of â€œclose to silk superior to cottonâ€. The low content of impurities can solve the problems of traditional cotton containing cottonseed hulls, fiber gums and other impurities, resulting in large losses in spinning, weaving, and serious dust in the production workshop; it has high strength and low elongation and can be customized. The special textile products rich in denier and length can meet different spinning processes and production requirements. In the same dyeing environment, blended spinning and natural cotton pure textile products can be dyed with similar color, uniform color and stable quality, thus solving the problem of natural cotton. Whiteness uniformity is poor, waste liquid is difficult to handle after dyeing, and environmental protection is poor.
According to Li Rongling, deputy general manager of Silkia Co., Ltd., in view of the high substitution of bio-based biomass materials in cotton, textiles produced with this kind of â€œsuper-imitation cottonâ€ will be better in terms of brightness and comfort of clothing. , Its blending with cotton helps to improve the smooth feel and dyeing of the yarn, and complements the advantages of fiber products. More importantly, its cost is lower than that of cotton and it is technically suitable for high-speed spinning, which can effectively improve labor productivity in the industry.
