Title: Fibrillation of crystalline (co)polyolefins - blended with inert particles, giving bulky yarn
Inventor: RUDIN ALFRED
IPC: D01D5/42
Filed: 1976-08-10
Abstract: Elongated fibres are produced by fibrillating an elongated polymer structure which is produced from a blend of crystalline (co)polyolefin(s) (I) and is not >20 wt. % inert particles (II) which remain solid throughout the process. The structure is drawn in the longitudinal direction until fibrillation occurs. The blend can also be made into a continuous tube, which is drawn biaxially to give a cellulose, fluid-permeable form. Specif., radial sterilising of the tube is carried out with a pressurised fluid inside the tube. (I) pref. is a (co)polymer of C2H4 or C3H6 and (II) is talc or glass fibres. The process is less time consuming than others and gives a bulky prod. suitably for textile applications. In an example a multifilament yarn was obtd. by extrusion of a blend of polypropylene contg. 5 wt. % talc and 2-stage orientation.
