synthetic and natural polymers

absorbent fibers have been employed for years in articles ranging from diapers to surgical sponges. initially, these products made use of cellulosic fibers solely as their absorbent material the superabsorbent material absorbs a considerable amount of fluid, and, because of its unique structure, is able to retain a substantial quantity of..

exterior body panel development

this conference proceedings contains 10 papers discussing new trends in exterior panel materials for automobiles. successful applications of reinforced reaction injection molding (rim) polyurethane composites to the pontiac fiero are discussed. a review is presented of thermoplastic olefin elastomers and potential applications. surface tr..

studies on applications of lipolytic enzyme in detergency l effect of lipase from candida cylindracea on removal of olive oil from cotton fabric

to investigate the effect of lipolytic enzyme on removal of triglyceride soils in laundry, the removal of olive oil from cotton fabric was examined by washing with an aqueous solution of lipase from candida cylindracea with and without surfactants at various washing temperatures and times. it was proved that at optimum conditions, the rem..

steam-explosion pretreatment of wood: effect of chip size, acid, moisture content and pressure drop

material balances for pentosan, lignin, and hexosan, during steam-explosion pretreatment of aspenwood, showed almost quantitative recovery of cellulose in the water-insoluble fraction. dilute acid impregnation resulted in more selective hydrolysis of pentosan relative to undesirable pyrolysis, and gave a more accessible substrate for enzy..

porous polymers && fusible films

new fibres and new polymer coatings based on poly(vinyl chloride) and polyurethanes, together with specially developed processing and coating techniques, offer potential advantages where fabrics are to be subjected to a harsh environment. thus the tensile strength, tearing strength and dimensional stability are imparted by the textile fab..

hydrolysis products inhibit adsorption of trichoderma reesei c30 cellulases to protein-extracted lucerne fibres

protein-extracted lucerne fibers (pelf) are an excellent lignocellulosic feedstock source in biomass conversion to the soluble sugars. pelf was hydrolyzed (85 carbohydrate conversion in 48 h at 45 $degree$ c) by the cellulase complex of trichoderma reesei c30 cultured in an 85(w/v) pelf - mineral salts medium. pelf hydrolysate inhibited b..
