Studies of Some Mechanical Properties of Watermelon Rind/Pawpaw Reel Reinforced Polyethlene Composites

ABSTRACT Some mechanical properties of water melon rind and pawpaw peel reinforced Low density polyethylene (LDPE) and Linear Low Density, (LLDPE) composites have been studied. Two sets of filler loaded LDPE and LLDPE composites were prepared using the injection moulding techniques at a processing temperature of 1900C Dispersing agent, silicon oil, was added to the composite as a plasticizer to improve flow, processabil...

Extruding Characteristics of FUTO Fabricated Extruder

ABSTRACT Optimum working condition for the FUTO fabricated extruder was established. The effect of screw speed on the viscoelastic property (die swell), sensory characteristic (hardness) and mechanical properties (modulus, ultimate strength and %elongation at break) of NNPC Polyolefin blends (HDPE/PP) were investigated. Screw speed had no effect on the mechanical properties of the unblended samples. Lower speed was found to fa...

Effects of Some Printing Variables on the Colour Yield of Reactive Dye Printed Cotton Fabric

ABSTRACT This thesis presents the findings of the investigation on the effects of some printing variables on the colour yield of reactive dye printed cotton fabric. The main print variables investigated are squeegee strokes, print paste viscosity, paste storage time and superimposed print. The printing pastes, (pastes A, B and C) used in this work were prepared using cassava starch, NaCl, NaOH and Procion reactive dye (Procion M); and were of dif...
