Publication number: 20150012018Abstract: Continuous processing methods are used for making absorbable polymeric non-wovens, with anisotropic properties, improved mechanical properties and without substantial loss of polymer molecular weight during processing. The method includes producing dry spun-non wovens from a polymer, and collecting the fibers using a rotating collector plate, preferably a rotating cylinder, to collect the non-woven instead of a fiberglass stationary collector plate. The non-wovens can be used for a variety of purposes including fabrication of medical devices.Type: ApplicationFiled: May 16, 2014Publication date: January 8, 2015Inventors: Kai Guo, Fabio Felix, David P. Martin

Patent number: 8926712Abstract: A solvent spun bamboo fiber with a high wet modulus and a producing method thereof are disclosed. The producing method includes: activating by adding a bamboo pulp into de-ionized water, adjusting the pH value, adding cellulase and adjusting the pH value by adding alkali; squeezing by vacuum dehydration; pre-dissolving by adding an aqueous solution containing 50-88% by mass of N-methylmorpholine-N-oxide; then dissolving by putting the above pre-dissolved mixture into a dissolver, heating, vacuumizing, dehydrating, dissolving, homogenizing and defoaming; spinning by spraying through a spinneret and forming a bamboo fiber by dry-wet spinning; water washing; bleaching; oiling; and drying. The present method is simple to operate, free of industrial pollution, low energy consuming, and highly safe. The bamboo fiber produced by the present method not only keeps the natural physical and chemical properties of bamboo fiber, but also has a high wet modulus without harmful chemical residues.Type: GrantFiled: September 7, 2010Date of Patent: January 6, 2015Assignee: Shanghai Lyocell Fibre Development Co., Ltd.Inventors: Kun Jiang, Xiaoliang Wang, Changli Zhu, Xin Wang, Dianhai Zheng
