2011-Recycling of poly para-phenylene terephthalamide (PPTA) fibre waste into nonwoven products

Recycling of poly para-phenylene terephthalamide (PPTA) fibre waste into nonwoven products: The importance of morphological changes and fibre structure to fabric integrity  T. Wright, C. Carr, K. Ryder and S.J. Russell Abstract The effect of mechanical recycling on the structure of Poly(para-phenylene terephthalamide) (PPTA) fibre waste to produce industrially serviceable nonwoven filter fabrics is discussed. A method of producing high burst strength fabrics from waste PPTA fibre is presented th.....
