Online Spinning of Commingled Yarns-Equipment and Yarn Modification by Tailored Fibre Surfaces


Article Preview

A unique melt spinning equipment for E-glass is compatibly combined with a melt spinning extruder to manufacture commingled yarns. The in-situ commingling enables to combine homogeneously both glass and polypropylene filament arrays in one processing step and without fibre damage compared to commingling by air texturing. Best composite performance is achieved with a sizing for glass fibres consisting of aminosilane and maleic anhydride grafted polypropylene film former, which enable a good strand integrity with the polypropylene yarn. The results of fundamental research on variation of technological processing conditions like diameter ratios, draw ratios, variation of cooling conditions and arrangements of intermingling are reported for glass fibre/polypropylene systems.
