Abstract: In the jig type textile finishing method and apparatus of the invention, the textile material (19) passes through a heated treatment bath (20) and is rolled alternately in one direction and in the opposite direction with high frequency or microwave electromagnetic waves (24) being applied to said textile material (19) while it is being rolled in and/or out. The power of the waves is determined, as a function of the optimum temperature for the reaction that is to be implemented, in such a manner as to maintain the temperature of the assembly (5, 6) constituted by the rolled-in textile material and the bath in which it is impregnated substantially equal to or greater than said optimum temperature.

Abstract: A method for producing a shaped non-woven comprises the steps of feeding fibers on a carding machine over a limited width, superposing on a receiving system the fibrous web leaving the carding machine and needling the superposed layers. The superposition is preferably obtained by winding over a cylindrical drain.The shaped non-woven obtained has a thickness gradually decreasing towards its selvedges. The obtained strip has a cross-section of an asymmetrical shape by longitudinal cutting along the median axis and optionally two longitudinal cuttings on the selvedge side.

Abstract: According to the invention, the treatment process for imparting flame retardancy consists in grafting a textile material containing nitrogen atoms in its polymeric structure, especially silk, with a phosphoric acid ethyenic ester of the general formula ##STR1## in which R.sub.1 is selected from the group comprising H and alkyls and R.sub.2 is selected from the group comprising alkylenes and alkylene oxides and/or polyalkylene oxides, for example phosphated ethylene glycol methacrylate, the grafting rate being less than or equal to 20%.

Abstract: According to the invention the material, in particular a textile, includes in its polymeric structure grafts forming complexes with at least one metal ion possessing recognized antiseptic activity. These grafts are formed by polymerization of unsaturated monomers with a complexing function, including the phosphate of ethylene glycol methacrylate or a polymerizable derivative of quinoline such as acryl 8-hydroxy quinoline. The process of preparation comprises a first step of grafting, for example by electronic irradiation of the material and impregnation with a bath of monomer, and a second step of impregnation of the grafted material with one or serveral baths containing the metal ion(s), such as copper, zinc, tin, mercury.

Abstract: A resonant high-frequency or micro-wave applicator for the thermal treatment of a flat material is disclosed. This applicator comprises a flat capacitor between the plates of which the material moves and an inductor which is constituted by a metal band extending transversely the plate acting as hot electrode. The inner face of the plate acting as ground electrode is divided into elementary sections by an assembly of longitudinal grooves. Preferably, the same applies to the inner faces of the plate acting as hot electrode and the inductor.

Abstract: The process of treatment according to this invention is applied to a textile piece--weave, knit or finished article--constituted wholly or partly by yarns of continuous filaments with adherent microfilaments, obtained by star--or lamellar spinning, for example comprising six to eight unitary microfilaments of 0.2 to 0.4 dtex. It consists in subjecting said piece, resting on a support screen, to the action of jets of water at a pressure of at least 4.multidot.10.sup.6 Pa, whereby the structure of the piece is modified and the unitary microfilaments are separated.

Abstract: The device comprises at least one element for immobilizing certain molecules contained in the medium to be tested. According to the invention, the immobilizing element is in the form of a hydrophilic material fixed on the surface of a plane hydrophobic material, such as for example viscose fibers (2) implanted by flocking into a sheet (3) of polyvinyl chloride. The device (4) further comprises:(a) a bottom plate (5) supporting the plane hydrophobic material,(b) at least one cavity (6) for the liquid medium to be tested, said cavity having an outlet orifice (9) situated above the plane hydrophobic material, and(c) scraping means (8) acting on the hydrophilic material (1) and capable of moving the liquid contained therein over the surface of the plane hydrophobic material (3).

Abstract: Apparatus for introducing fabric article parts to an assembling machine which comprises a first slide assembly incorporating a device for entraining the parts along the slide assembly and thence into the machine. The fabric article parts are initially suspended from a second slide assembly and a caliper which are movable along separate, but substantially parallel, paths leading to the intake of the first slide assembly.

Abstract: The invention comprehends a method of twisting core strands, of the type comprising a sheath of fibres surrounding a central strand, a method in accordance with which a sliver of fibres is drawn between a point of entry of the said sliver and a pair of downstream drawing cylinders, a central strand is drawn under constant tension and is introduced without drawing into the sliver upstream of the said drawing cylinders, characterized in that a torsion in one sense and the other is conferred successively on the assembly constituted by the sliver of fibres and the central strand downstream of the said drawing cylinders.

Abstract: A device is disclosed for detecting defects in needles on a knitting loom which is operating. The device comprises at least one Hall probe magnetic detector the active surface of which has a width less than the thickness of the needles to be detected. The detector is mounted such that the needles all pass successively in front of it during their working movement, and an electronic circuit transforms the signals received from the magnetic detector into a signal for controlling the stoppage of said loom. The electronic circuit comprises first and second electronic circuits each of which is adapted to supply a signal for controlling the stoppage of the loom.

Abstract: A yarn supply device for a rectilinear knitting machine capable of supplying the needles of the machine with a predetermined quantity of yarn irrespective of the speed of operation of the machine. The supply device comprises a yarn feed unit incorporating a drive member such as a pulley around which the yarn is wound in order to obtain positive drive engagement, the pulley being driven by an electric motor energized with an error signal derived from the output signal of a transducer sensitive to the actual displacement speed of the yarn feed device, and a signal representing the desired speed derived from the displacement and speed of a cam bar and thrower bar of the knitting machine. Arrangements are made for compensation in the error signal for the different stretch in the yarn in dependence on the position of the thrower with respect to a fixed yarn guide, and also for the inertia of the drive member of the yarn feed unit.
