This document discusses innovations in needle punching technology for medical textiles. It begins by describing how medical textiles are used for hygiene and healthcare. It then discusses the classification and constituent elements of medical textiles, including polymers, fibers, yarns, fabrics, and final textile medical products. The document focuses on the needle punching process, including fiber opening and blending, nonwoven carding, cross-lapping, needle looming, winding, and cutting. It describes innovations like cyclopunching that allow for higher density needling. The document concludes by discussing the potential of these technologies in markets like the US and opportunities in medical textile products.

16. NEEDLE FELT TECHNOLGY
Felting needles penetrate
through crosslapped fibre
batt
Barbs of felting needles
catch and transport fibres
By means of this fibres
entangle, fibre batt
consolidates and needle felt
with strength properties is
created
