Publication number: 20220307160Abstract: The invention relates to a Lyocell fiber with recycled cellulose, which uses recycled cellulose pulp to dissolve in the spinning solution. The weight percentage of the recycled cellulose in the spinning solution is 30% to 55%. The Lyocell fibers of the invention also have hydrophilic, cooling, drape, antistatic, and biodegradable properties compared to the Lyocell fibers without recycled cellulose.Type: ApplicationFiled: March 26, 2021Publication date: September 29, 2022Inventors: Wen-Tung Chou, Shao-Hua Chou, Je-Yuan Yeh, Hsiao-Chi Tsai

Patent number: 10351971Abstract: This application describes a method of preparation of a natural graphene cellulose blended fiber, which comprises using a graphite powder as a raw material for preparing a graphene solution, adding the graphene solution to a slurry formed by mixing and dissolving a wood pulp with N-methylmorpholine N-oxide (NMMO), removing the water content thereof to form a spinning dope, and then spinning the spinning dope by a Dry-Jet Wet method to manufacture a natural graphene cellulose blended fiber. The present method does not require a highly toxic hydrazine hydrate solution. Further, by increasing the adding ratio of the graphene solution in the manufacturing process, control of the antistatic properties and thermal transferring functions can be achieved, and thereby various requirements of different consumers can be satisfied. Besides, the fibers can decompose naturally after being used, and thus the product is harmless, natural, and environmentally friendly.Type: GrantFiled: September 29, 2016Date of Patent: July 16, 2019Assignee: ACELON CHEMICALS AND FIBER CORPORATIONInventors: Wen-Tung Chou, Ming-Yi Lai, Kun-Shan Huang, Shao-Hua Chou, Chia-Yu Hsu
