?IMPROVEMENT OF Low GRADE JUTE FmRE BY ENZYMATIC PRETREATMENT WITH HIGHER PIN DENSITY IN THE FINISHER CARD

Abstract

Low grade jute fibres are mainly used for sacking weft batches. In processing technology these fibres draw least attention
of the millers. In the present work enzymes were used to improve the softening of hard fibres for further processing. The
enzymes were extracted by fermenting indigenous wheat bran as substrate with the fungi, Aspergillus spp. The carding
effect was improved by introducing higher pin density at the sacking finisher card. By pretreatment with A terreus
enzyme, 36.37% jute cutting was used in hessian weft batch which reduced the batch cost without impairing yarn quality
and production efficiency. Moreover, the use of modified finisher card improved the yarn quality of both, the enzyme
treated and untreated batches.
