  • Patent number: 8952146
    Abstract: The present invention provides a process for producing low fibrillating cellulose fibers by a dry-jet-wet spinning process wherein cellulose is treated with a solvent containing imidazolium ionic salt in a spinneret maintained at a temperature of 100-120° C. and the spun fibers drawn to the coagulation bath containing ionic salt with the draw ratio less than 5, to produce fibers with fibrillating index less than or equal to 3.
    Type: Grant

  • Publication number: 20080090939
    Abstract: A biodegradable polymeric composition includes 99.5 wt. % to 40 wt. % soy protein and 0.5 wt. % to 60 wt. % of a first strengthening agent that consists essentially of a polysaccharide selected from the group consisting of agar, gellan, and mixtures thereof. The composition is substantially completely soluble in water at a pH of about 7.0 or higher. A biodegradable composite includes a fiber mat and the described biodegradable polymeric composition. A biodegradable molded thermoset solid article is obtained by subjecting the described biodegradable polymeric composition to conditions of temperature and pressure effective to form the thermoset solid article.
