A felting of synthetic fibers having an embossed pattern that forms depressions in at least one surface of the felting is disclosed. The surface of the felting with depressions contains, in at least the area of the depressions, a layer of small hollow spheres that are bonded to one another and to the felting by means of a binding agent. The layer of hollow spheres fills up, at least partially, the depressions in the surface of the felting produced by embossing. This reinforces and strengthens the thinner areas of felting in the vicinity of these depressions. When the reinforced felting is applied to a shoe upper, for example, the resulting upper has improved stiffness and strength. Furthermore, the excessive penetration of adhesive into the felting, which can cause a spotty or uneven appearance of the reinforced upper, is prevented. Resistance to splitting and separating is likewise improved.

The invention relates to a clothing item or piece of clothing, in particular, for direct wearing on the skin. The piece of clothing comprises at least two different yarns (1,2). The yarn (2), facing the skin, has a completely sealed and smooth surface and is in one piece. In a version thereof, the yarn (2), comprises a number of individual filaments (21) collected into one thread. Said yarn has a sealed and smooth surface.

The invention relates to a textile construction for using in passenger restraint systems. Said textile construction is characterised in that it contains plastically deformable filaments which enable the surface of the textile construction to increase when pressure is applied in at least one surface direction. The inventive textile construction is also provided with an especially elastic coating.

The present invention relates to polyester yarn which is characterized in that it is a multifilament yarn substantially comprising polytrimethylene terephthalate, and as well as the strength from the stress-strain curve being at least 3 cN/dtex and the Young's modulus being no more than 25 cN/dtex, the minimum value of the differential Young's modulus at 3-10% extension is no more than 10 cN/dtex and the elastic recovery following 10% elongation is at least 90%. Furthermore, said polyester yarn can be obtained by a method of producing polyester yarn which is characterized in that multifilament yarn obtained by the melt spinning of polymer substantially comprising polytrimethylene terephthalate of intrinsic viscosity Ä eta Ü at least 0.7 is hauled-off at a spinning rate of at least 2000 m/min and, without winding up, subjected to drawing and heat-treatment, after which it is continuously subjected to a relaxation heat treatment at a relaxation factor of 6 to 20% and wound up as a package. Moreover, the present invention also relates to a woven material of outstanding soft-stretchability which is characterized in that the aforesaid polyester yarn is used as the warp yarn and/or the weft yarn in the form of twisted yarn of twist coefficient 10,000 to 20,000. In this way, it is possible to produce yarn stably at a high yarn production rate without package tightening occurring, and, as well as there being little variation in properties in the fibre lengthwise direction, when made into fabric, said fabric stretches at low modulus so there is little sense of tightness, and it is possible to provide polyester yarn and woven materials with a soft handle.

A yarn of collagen fiber of animal leather and the manufacturing process thereof, characterized in that the yarn is made of 1-100 % by weight of collagen fiber of animal leather, and 0-99 % by weight of textile fiber. The yarn of collagen fiber is made by the following steps: choosing raw materials, loosing fiber, assorting, blending, carding, drawing, and twisting; if using rawhide, the above process should also add the steps of liming, washing, de-liming, tanning and dehydrating. The raw material for making of yarn can be rawhide of any animal, as well as any leather waste material or worn-out leather. The yarn has excellent properties, including high tensile strength, abrasion resistance, softness, water adsorption, oil adsorption, flame-retardation, and can be woven, knitted and braided. The yarn can be used to weave high quality fabric with high count and high strength for the four seasons, which greatly broadens the application field of animal leather, improves the utilization of the leather, and provides a spinnable fiber for the textile industry. The present invention can be widely used in textile industry.

The invention concerns woven straps having transverse contractions, as well as a method and apparatus for their manufacture. Contractions are formed along straps having a continuous unchanging weave and continuous selvedge by altering spacing of warp yarns during weaving. The warp yarns are spaced by a V or fan shaped support which is vertically movable to cause corresponding width variations in the straps.

This invention relates to a novel type of textile reinforcement adapted to be used for making laminated complexes, of the type constituted by at least one layer of reinforcing yarns. The yarns are bonded together by adhesion with binding yarns, disposed transversely, in a small proportion with respect to the reinforcing yarns. Reinforcing yarns are spaced apart from one another so as to form stable and undeformable holes of definite shape. Additional binding yarns are disposed on either side of each of the strips of reinforcing yarns.

1. Process for assembling, by jointing, two surfaces A and B, these surfaces being made of various materials such als glass, plastics, metal etc., characterized in that it consists in : a) applying to the surface A a seal in the shape of a strip of a thermoplastic material, based on a polymer chosen from the group comprising thermoplastic polyurethanes, polyetheramides or mixtures of both these thermoplastic polymers, b) placing the surface A so as to face the surface B, via its seal, and c) producing the assembly by melting the surface layer of the seal which is facing the surfaces B, placing in contact and cooling under a slight pressure.
