Study On Properties Of Bamboo Yarns With Cellulase Treatment

The more living standard improved, the more soft goods' function need to be hold. Sothe textile technologists make efforts to creat a new type of fabric or insert special effect informer fabric so that can get a new variety differed with others. In this paper a new waywhich combined cellulose enzymatic with traditional chemical way react to the bambooyarn has been applied. Roundly research the new type fiber property and analyse thedifferent changes of yarn which has been treated. Find a perfect technics to make thebamboo fiber amend certain fault and still possess the original excellent property. So thatcan produce some products with good properties and can provide theoretics furtherresearch.It could be found after lots of experiments in bamboo fibers' property research that theabsorbs moisture of bamboo fibers' is good. The length of fibers' are more change thanramie. It is very strong with a tenacity and high initializatial modulus. It belongs thecellulose fiber of high strength combined less elongation.It could be found after lots of experiments in activity of cellulose and treating bamboofibers with cellulose that Filter paper, CMC were used as substrate to measure the fullactivity, EG activity of enzyme, respectively. The activeity of cellulase BTH is mosthighest in the cellulases. As cellulose concentration increase, it is easy to see therelationship between weight loss and cellulose concentration, meantime, when thecellulose concentration is 5%, the capability in combined object has saturated. Thepretreatments of water-acetone-sodium hydroxide solution proved to be more effects thanthe pretreatment of sodium hydroxide solution and lead to a drastic change of finestructure and a considerable improvement of accessibility and reactivity of bamboo fibers.The best technics of cellulase dealing with bamboo fiber is the condition that the cellulose concentration is 25ml/l, the tempreture is 55℃, the action time is half an hour, theproportion between solute and solution is 1:30.It could be found after lots of experiments in dealing with bamboo yarns with cellulasetechnics combined pretreatment's technics. The bamboo yarns shows some changes inproperties. The property of celluloseⅠis not change, the discomposed temperaturedeclines. Regain of bamboo fibers declines, The orientation of molecules are not asregular as untreated yarns, tenacity of yams less than the untread yarns, but the elasticproperties are more better, meantime, the surface of yarns get smoother than untreatedyarns. The treated yarns still possess good thermal property. The fibers slipped from dealtyarns without tension are more than untreaded yarns which are more than treated yarns intension. The same condition in initializatial modulus, treated yarns in tensions' is thehighest in tenacity, but the elongation is reversed. The elongation recovery capability oftreated yarns without tension is less than untreated yarns and yarn in tension. Twist yarnscan improve property of friction.
