High-tech fiber materials to achieve a breakthrough
Lyocell fiber has already gained a certain reputation in the industry. It is a kind of green and environmentally friendly regenerated cellulose fiber, which has natural fiber properties such as hygroscopicity, air permeability, comfort, gloss, dyeability and biodegradability. It also has the advantage of high strength of synthetic fiber. Its strength is close to that of polyester, which is much higher than that of cotton and ordinary viscose. It has broad application prospects in textile and other industries.
In the domestic Lyocell fiber production process, for the first time, the design, integration and software development of the computer control system for the whole process of producing 10,000 tons of new solvent cellulose fibers has been completed. The entire process of cellulose fiber production with the new solvent method has been automated, and the core control has been mastered. Technology; Integrated with 10,000 tons of new solvent cellulose fiber production equipment, optimized production technology, for the first time to achieve a stable compliance production of 10,000 tons of new solvent cellulose fibers, and in the new 10,000-ton solvent cellulose fiber technology On the production line, a systematic theoretical study was conducted and the actual production rules that affect product performance were obtained, breaking through the theoretical bottleneck of fiber preparation, and at the same time conquering the solvent purification and recovery and concentration technologies.
The promotion and application of this project has broken the monopoly of foreign countries on China's Lyocell fiber production technology, significantly improved China's new solvent cellulose fiber production technology and equipment, and made positive contributions to structural adjustment and transformation and upgrading of China's chemical fiber industry.
The development of seaweed fibers and the demand for resources from the sea are the inevitable choices for the continued advancement of China’s economic and social development in the face of increasingly depleted land and petroleum resources. However, alginate fiber has the problems of low mechanical properties, low productivity, dissolution in alkaline solution in the presence of saltwater, fibrillation of primary fibers, and difficult dyeing of fibers, which have not been resolved for decades. This limits the application of seaweed fibers to “ Narrow-facet narrow medical fiber field for the development of medical dressings and care materials. The "seaweed fiber preparation industrialization technology and equipment" developed by Qingdao University and other organizations has for the first time achieved an increase in seaweed fiber strength, production capacity improvement, salt and alkali-resistant detergent (saponification-resistant) washing, and no dehydrating agent ( Alcohol, acetone, etc.) Breakthroughs in key technologies such as fiber splitting and colored fiber preparation. Currently, it has built an annual production capacity of 800 tons of automated flexible seaweed fiber production line with reliable operation and stable product quality. It has developed and successfully produced more than 20 series of seaweed fiber products such as textiles, clothing, biomedicine, medical care, etc., breaking the use of seaweed fiber at home and abroad. Medical bandages narrow fabrics and care material singularity.
