Performance of Blended Felts of Wool and Polypropylene Fibers

Impact of blending wool (W) with polypropylene (P) fibres on performance of felt has been studied. Blended Felts of three ratios, 70W 30P, 50W 50P and 30W 70P were prepared in three thicknesses viz.1-2mm, 2-3 mm and 3-4 mm.100W felt was also prepared for base reference. Dimensional, mechanical and functional properties of felts were determined. It was found that thickness and blend ratio of felts influence their performance. Improvement in strength and abrasion resistance and compressibility of felts is observed after blending polypropylene fibre with wool fiber.
