An Ivestigation on Abrasion Resistance And Bending Rigidity of Recycled Nonwovens Including Blanket Trimmings

In this study blanket trimmings and mechanically recycled fibers were blended and softly pre-needlepunched to be used as innerlayers of conventional needle-punched nonwovens. The outer layers from three types of raw materials (polypropylene, recycled polyester and mechanically recycled fibers) and the control groups were produced by classical needle-punching at two different needle-punch densities. Abrasion resistance and bending properties of the end products were investigated considering recycled layer ratio, raw material type and needle-punching density through standard test methods. Among all types, the highest abrasion cycles and bending rigidity values were observed for the PP outer layered products. Increase in needling density increased the abrasion cycles between 10%-20% and increased bending rigidity 3%-8% among the overall. Comparing the fabrics with recycled layer of 20% to control groups, abrasion resistance was preserved between 67% -75% and bending rigidity was preserved between 86%-93% at overall.
