Abstract: newline After reviewing past work into the enzymatic treatment of cotton newlineyarns and composites an account is given of the cellulase treatment of cotton newlineyarns produced from two different spinning technologies and hybrid fibre newlinecomposites and nano composites which represent one of the major problems newlinein finishing The shortcomings of the knowledge are shown to be that newlinealthough a large number of papers have been published on the enzymatic newlinetreatments of cotton yarns there have been no systematic studies on the newlineresponse of regular and compact yarns and there have been virtually no newlineattempt to characterise the substrates in terms of their structures newlineFour yarns which comprised of 60 Ne and 80 Ne regular and newlinecompact yarns were subjected to cellulase treatment under the same newlinecondition and their tenacity elongation wickability minimum twist of newlinecohesion and bending rigidity were examined Short staple natural fibres newlinesuch as sisal jute banana reinforced thermoplastic composites are newlineincreasingly gaining attention for their emerging applications in the field newlineof aerospace automotives construction textiles etc For producing hybrid newlinecomposites mercerised cotton cellulase treated cotton and sisal fibres were newlineused The mechanical thermal and morphological characteristics of hybrid newlinecomposites and nano composites were studied PP composites were prepared newlineby HAAKE Rheomixer followed by compression moulding Cloisite 25A was newlineused to improve the hybrid fibre composites Mechanical tests showed newlineconsiderable improvements The morphology of hybrid composites and newlinenanocomposites were examined by SEM Scanning Electron Microscopy and newlineXRD X ray diffraction newline
