Abstract: The invention comprises textured continuous filament yarns of a synthetic thermoplastic material, especially a polyester such as polyethylene terephthalate in which each filament comprises, on the microscopic scale, alternating zones whose diameter increases and decreases progressively between at least two different mean values, the zones of smaller diameter corresponding to zones of higher crystallinity index and higher molecular orientation and vice versa, each filament having a large apparent bulk, and the yarn as a whole having tridimensional crimp. Preferably the filaments have similar, though somewhat attenuated, differences along their length on a macroscopic scale, giving them a knop appearance. The yarns are made by partially stretching a multifilament yarn in the presence of a crack-producing agent, such as an aqueous lower alkanol at ambient temperature, giving the partially stretched yarns a thermal treatment in a relaxed condition, and subjecting them to a twist-set-untwist treatment, in which the heat setting step may also provide part of or the whole of the said thermal treatment.

Abstract: The specification discloses an apparatus and method of treating textiles yarns with a liquid, in which the yarn is passed around a portion of the periphery of the disc. The lower perphery of the disc dips into a trough, the width of which is only slightly greater than the axial length, and the liquid flow through the trough in the same direction as the lower periphery of the disc. A very uniform coating of the perphery is thus achieved.

Abstract: The Specification describes an apparatus for removing thread wastes from a textile thread carrier, in which a lifting member, having an elongate flattened point shape, is inserted by relative movement between the lifting member and carrier, between the carrier and the threads therein. The thus lifted threads are cut by a breaking member which may be a knife or a heated needle on the top of the lifting member. Alternatively a heated member, a rotating disc or fixed knife may be inserted in a slot in the lifting member.

Abstract: The specification discloses an apparatus for interlacing continuous filaments to form a yarn having a coherent structure, due to the action of at least one high velocity fluid jet. Extending through a main body member of the apparatus is a keyhole cross section passage having a cylindrical portion through which the filaments run, and an isosceles trapezoidal cross section prismatic portion into which the fluid jet is symmetrically projected.

Abstract: IN THE PRODUCTION OF FILAMENT- OR FILM-FORMING POLYALKYLENE TEREPHTHALATES BY TRANSESTERIFICATION FOLLOWED BY POLYCONDENSATION, ZINC AMINOTRIETHANOLATE IS USED AS THE TRANSESTERIFICATION CATALYST, PREFERABLY IN COMBINATION WITH THE USE OF BISMUTH AMINOTRIETHANOLAMINE AS THE POLYCONDENSATION CATALYST. MUCH SMALLER AMOUNTS OF THESE CATALYSTS CAN BE USED THAN OF PRIOR ART CATALYSTS, AND THE PRODUCT HAS A HIGH DEGREE OF THERMAL STABILITY.

Abstract: THE INVENTION RELATES TO PADDING MATERIAL FOR UPHOLSTERY AND THE LIKE, AND A METHOD OF MANUFACTURE THEREOF IN WHICH A LARGE NUMBER OF CONTINUOUS, PREFERABLY CRIMPED, CHEMICAL FILAMENTS ARE ARRANGED SIDE-BY-SIDE TO FORM A FLAT SHEET. THE SHEET IS FORMED INTO DEEP UNDULATIONS, E.G. BY PASSING BETWEEN ROLLERS ROTATING AT DIFFERENT PERIPHERAL SPEEDS AND THE UNDULATIONS ARE SPRAYED WITH A RESIN WHICH IS THEN HARDENED TO FIX THE UNDULATIONS IN POSITIONS.
