摘要： A process for making filament yarn products is disclosed in which polypropylene, having a molecular weight distribution of less than about 7 and a melt index between about 20 and about 60 is melt spun to produce an as-spun product or additionally interlaced before take-up, twist-drawn, heat set, draw-textured by false-twisting, simultaneously draw-textured, sequentially draw-textured, draw-twisted, draw-Taslan textured, stuffer box crimped and cut into staple fibers, or a plurality of yarns are simultaneously draw-textured by false-twisting while reversing the direction of twist of alternate yarns and thereafter interlacing. Products of improved tenacity, improved birefringence and low elongation are produced.

摘要： Description is made of an increased volume synthetic fibre consisting of a porous central core and a large number of short porous lateral threads integral with the core and distributed along the whole length of the fibre so as to form a voluminous branching structure. There is also a description of the procedure used to produce the fibre, which consists of the mixing of a synthetic polymer with an inflating agent which expands when heated, the spinning by means of melting the mixture which results in the inflation and fringing of the threads produced, caused by the inflating agent, followed by the drawing and fixing of the threads thus produced while they are still hot. Examples of the use of the fibres in question are given by filters and padding.
