Abstract (en)
[origin: EP0129317A2] Melt-spun, rough surfaces, fibres of a fibre-forming polyamide containing at least 10% by weight of another polymer, in preference either polyethylene or polypropylene, which is immiscible in a melt of the fibre-forming polyamide and has a lower melt viscosity than the fibre-forming polyamide at the spinning temperature, such other polymer being present in the melt spun fibres as microfibrils and a process for providing such fibres.
