Preparation and Characterization of ABS /CPVC/SHORT GLASS FIBER composites: Cop’s sleeve for textiles industries

plastics engineering

ABS/ SGF (short glass fiber) composites have a broad range of applications likes household appliances, automobiles, and textile industries as cops’ sleeve. ABS (Acrylonitrile butadiene styrene) is a terpolymer having good structural stability and processibility. The reinforcement by SGF makes this material structurally stable and provide the better abrasive wear properties for strong grip of yarn. When ABS /SGF is used as cops sleeve it pulls out (elongation) from original shape and cracks occur on sleeve in 20-25 days, due to compressive force of wound yarn. To enhance the compressive strength and dimension stability ABS and SGF were melt blended with CPVC in twin screw exruder.The various ABS//CPVC/SGF composites material were prepared by composition of 5,10 and 15 weight percent CPVC in ABS/CPVC/SGF. The specimen was prepared by the injection molding process. The composites having different ratio of CPVC content were tested to determine tensile, flexural, impact strength hardness and also test SEM.The invention relates to enhance the compressive strength and dimension stability of ABS /SGF composites cop’s sleeve.
