ENDLESS SHAPED ARTICLE OF ULTRA-HIGH MOLECULAR WEIGHT POLYLEFIN FILAMENTS AND/OR STAPLE FIBRES AND A PROCESS FOR MAKING THE SAME

摘要

Endless shaped article, comprising at least partly fused ultra-high molecular weight polyolefin filaments and or staple fibres. Also claimed is a process for producing the endless shaped article by winding a fibre (1) of the ultra-high molecular weight polyolefin around a pair of wheels (2, 3) to form a loop, heating the fibres to a temperature below the melting point at which the fibres at least partly fuse and stretching the loop by increasing the distance between the wheels, while rotating the wheels.
