A study on solid structure of regenerated cellulose fibers related wit fibrillation (Japanese)

It is well known that the cupro, polynosic and organic solvent span rayons, such as Tencel, and loycell fibrers are easy to filbrillate. The rayon fiber is difficult to fibrillate. We developed fibrillation-resistant cupro (cupro2) by means of a new spinn

Improved nylon and polyester

AlliedSignal has introduced new versions of its fiberite 2000 polyester and Anso-tex nylon. It now has 10％ higher tenacity, shows 25％ less shrinkage, has better colour uniformity and greater fade resistance. The yarn is produced in a range of counts from 840-2600 denier and in 14 colours, including black.

Kanebo marketing biodegradable fiber for apparel use

Kanebo Spinning Corp. of Japan is producing apparel fabrics incorporating Lacron fibres. Lactron fibres are made from lactic acid which is derived from corn startc. The fibres are biodegradable. Kancbo's Lactron fibres are stronger than other fibres made from lactic acid due to the spinning method used, it is claimed. Lactron is being bel..

Preparation and characterization of crosslinked porous silk fibroin gel

In order to develop new biomedical materials, the preparation and characterization of crosslinked porous silk fibroil gel (CPFG) were investigated by using ethylene glycol diglycidyl ether (EGDE) as a crosslinking agent. The CPFG was prepared by freezing (-50℃&&-5℃) and thawing a homogeneous fibroin solution containing EGDE. The average..

Tangential Membrane Filtration

Membrane processes include ultrafiltration and reverse osmosis. Flow diagrams and performance specifications reveal the effectiveness of membranes during the recovery of waste effluent and the recycling of water at textile finishing plants. Physical and chemical processing techniques result in less bulk nd increased ease of operation. Bio..

Deactivation Behaviors of Zeolite and Silica-Alumina Catalysts in the Degradation of Polyethylene.

Experiments on the degradatin of polyethylene in a fixed bed flow reactor compared the effectiveness of three zeolite and silica-alumina (SA) catalysts. HZSM-5, HY, and H-mordant (HM) zeolites differed in acidic properties and pore structures. Polyethylene degradation at 375 degrees centigrade over HZSM-5 catalyst resulted in the producti..

New Denim Technology for the 21st Century

Benninger's Ben-Indigo system for dyeing and finishing denim requires considerably less water and power and offers improved control of the dye, resulting in less effluent. The system uses three immersion baths and fixes the dye with fewer reducing agents and chemicals than do conventional machines. The Ben-Link system for tying-off yarns ..

Structure of Regenerated Cellulose Fibers from DMAc/LiCI Solution.

Research on the structure of regenerated cellulose fibers spun and annealed solutions of cellulose in dimethylacetamide and lithium chloride to form fibers. The fibers showed a range of polymorphs with different coagulants and annealing temperatures. Prior to annealing, as-spun fibers showed Cell III morphology. Fibers annealed at 170 deg..

Complete recycling of textile components from cotton/polyester fabrics

An environmentally friendly method for separation and recycling of textile components from blends containing cotton or rayon and poly(ethylene terephthalate) has been discussed. The polyester component was hydrolyzed to initial monomeric materials in basic conditions which did not affect the strength of the accompanying cellulosic part (c..

Apparatus for making hollow, multicomponent insulation fibres

An apparatus for making multicomponent hollow fibres suitable for insulation comprises: a rotary spinner with a housing, having a wall which is divided into two compartments for receiving two thermoplastic materials; several nozzles associated with the wall, having two passages through which the two thermoplastic materials flow to an orif..
