摘要： A process of melt spinning a fibre-forming thermopias- tic polymer, more particularly polyethylene terephthalate, polyhexamethylene adipamide or polypropylene, at a minimum wind up speed of 1 kilometre per minute in which there is added to the fibre-forming polymer, between 0.1 % and 10% by weight of another polymer which is immiscible in a melt of the fibre-forming polymer, such other polymer having a particle size of between 0.5 and 3 microns in the melt with the fibre-forming polymer immediately prior to spinning and novel melt spun fibres produced by such a process and in which the other polymer is in the form of microfibrlls.

摘要： A process of melt spinning a fibre-forming polymer having a high viscosity, more particularly polyethylene terephthalate having an intrinsic viscosity greater than 0.70 or nylon 66 having a relative viscosity greater than 45 and more preferably greater than 55, in which before melt spinning, there is added to the fibre-forming polymer between 0.1% and 10% by weight of another polymer which is immiscible in a melt of the fibre-forming polymer and which has an average particle size less than 3 microns in the melt immediately prior to spinning.

摘要： A process for the production of heterogeneous articles such as heterofilaments and fibres containing a plurality of solid phases, comprises supplying a thermoplastic first material in particulate solid form to a surface of rotation of a rotating body so that it travels across said surface towards a discharge zone due to forces generated by the rotation of the body, melting the thermoplastic first material as it travels across the surface, supplying a second solid material to the surface, discharging both materials together from the discharge zone by centrifugal forces, and solidifying the thermoplastic material to form the heterogeneous article. The second material is preferably also thermoplastic and further solids, especially reinforcing fibres, can also be incorporated likewise.
