"Huasai fiber" with wood pulp as the main raw material, using morpholine oxide as solvent, in the way of physical dissolution, spun cellulose fiber. The unique closed production process enables the solvent recovery rate to reach more than 99.7%. It has the characteristics of renewable raw materials, clean production and degradable waste, and is known as the "green fiber of the 21st century". The products have the "comfort" of cotton, the "strength" of polyester, the "luxury beauty" of wool fabric and the "unique touch" and "soft pendant" of silk. 100 percent natural materials, coupled with environmentally friendly manufacturing processes, make the lifestyle based on the protection of the natural environment, fully in line with the needs of modern consumers.

Jiangsu Jinrongtai New Material Technology Co., Ltd. annual output of 300,000 tons of Lessel fiber test received high attention at home and abroad. As the leading unit of Lessel fiber in China, China National Textile Science Research Institute Co., Ltd. sent a professional technical team to Jinrongtai for comprehensive diagnosis, improvement of key and key equipment, replacement of relevant devices and valuable suggestions. During the test period, we provided all-round assistance from single debugging, extension operation, automatic control to the test run with materials. Under the joint efforts of all the cadres and staff of Jin Rongtai and the technical team of China Textile Institute, we overcame the difficulties and succeeded in trial production, laying a foundation for the production of 300,000 tons of Lessel fiber. In the future, JinRongtai will actively adapt to the new trend of green development, strengthen cooperation with all parties, and make an important contribution to the structural adjustment of Chinese chemical fiber industry, the transformation and upgrading of the regenerated cellulose fiber industry, and the green manufacturing of textile fiber raw materials.
