On July 5th, China National Textile and Apparel Council organized three appraisal meetings: Research and industrialization of high fluffy elastic antibacterial polypropylene two-component spunbonded nonwovens, industrialization technology development of UHMWPE differential fiber and individual stab-resistant and cut-resistant textiles, key technology and new product research and development of low strength and high permeability textiles.

The appraisal committee believes that the three projects have fulfilled the requirements of the task book, and the overall technology has reached the international advanced level, and unanimously agreed to pass the appraisal.

The project "Research and Industrialization of High Fluffy Elastic Antibacterial Polypropylene Two-component Spunbonded Nonwovens" is jointly undertaken by Hengtian Jiahua Nonwovens Co., Ltd. and wuhan textile University. The project optimizes polypropylene raw materials and polypropylene-ethylene block elastomers with different isotacticity and melt index; Two-component parallel spinning and filamentation technology of polypropylene were studied, and superfine spiral fiber and high fluffy nonwoven materials were obtained. The network topology design method was constructed, and the parallel/sheath-core/parallel composite spinning technology was overcome. The high elastic composite nonwoven was obtained, and the industrial production of high elastic and comfortable bicomponent spunbonded nonwoven was realized. Based on the principle of biomimetic decoration of mussels, the production technology of antibacterial functional finishing was developed, the production technology system of functional finishing was established, and a series of medical protective materials with high barrier and comfort were developed. The project has formed an annual production capacity of 15,000 tons of SMS bicomponent spunbonded nonwovens and 15,000 tons of bicomponent spunbonded nonwovens. The product has excellent performance, which meets the requirements of national standards, European Union and American standards. The project products have been widely used in emergency, medical treatment, personal hygiene and other protection fields, with remarkable economic and social benefits.

The project of "Industrialization Technology Development of UHMWPE Differentiated Fiber and Individual Spin-proof and Cut-proof Textiles" is jointly undertaken by China Textile Institute (Zhejiang) Technology Research Institute Co., Ltd., China Textile Research Institute Co., Ltd., Jiangsu Jiujiujiu Technology Co., Ltd., Jiangsu Jiujiujiu Special Fiber Products Co., Ltd. and Henan Bangwei Hi-Tech New Material Technology Co., Ltd. The project studied the preparation of high-concentration UHMWPE spinning solution and the environmentally-friendly and efficient tetrachloroethylene extraction technology, and overcome the technical difficulties existing in the conventional spinning process, such as low solution concentration, low production efficiency, flammable extractant, long process, and much residual solvent in finished products. UHMWPE fiber with low cost and high abrasion resistance and cutting resistance was developed by adding modified nano-powder stock solution. Weft-knitted fabric of fencing clothing with light weight, high puncture strength and good comfort was developed by coating UHMWPE fiber with moisture-absorbing and sweat-releasing polyester fiber and combining with fabric design. Through the control of yarn twist and the design of weave structure, a lightweight civil protective fabric with both stab-proof and cut-proof properties and comfort was developed. The project has built production lines of 1,000-ton UHMWPE fiber, fencing clothing fabrics and stab-resistant and cut-resistant fabrics, with a complete industrial chain. The product has excellent performance, good feedback from users and remarkable economic and social benefits.

The project "Research and Development of Key Technologies and New Products of Textile with Low Strength and High Permeability" is jointly undertaken by Qingdao University, Shandong Kanghui Health Technology Co., Ltd., Shandong Textile Research Institute, Weifang Jiacheng Digital Materials Co., Ltd., Yantai Mingyuan Creative Life Technology Co., Ltd. and Shandong enron nano Industrial Development Co., Ltd. The project independently developed low-strength and high-permeability multi-component strontium ferrite magnetic source materials, and prepared micro-nano magnetic particles by high-pressure homogenization technology; Invented the coating technology of synthetic fiber tow based on microfluidic-wet method and microfluidic-melting, and realized the high load of fiber magnetic source material. A series of magnetic functional textiles were developed, and an evaluation method of magnetic therapeutic effect of magnetic textiles based on infrared thermal imaging and wearable monitoring was put forward. The implementation of the project has effectively improved and improved the quality level of domestic magnetic fibers and magnetic health textiles, expanded the application scope, and can replace related imported products, which is beneficial to domestic related enterprises to reduce production costs and enhance product added value and core competitiveness.
