PATENT AS AFRICAN AND MALAGASY INDUSTRIAL PROPERTY P. 887 Yaounde (Cameroon) № 01286 THE V * 31 December 1964 to 18 hr 36 requested Mn to ioio.a.m.p.i. (G.P. no. 51,684) by the Company rhodiacëta, residing in France. Delivered 15 February 1969, published at The present invention provides ideal - poisoning in the manufacture of textile articles whose shape must have good support and certain stiffness, such as hats, bra and the like, and the resulting articles. When textiles in themselves not very rigid must be used in the production of articles that must have rigidity, it is neces - at which it providing a framework composed by a assembly of rigid elements such as textile genus singalette, wires or wire meshes, or not, strings piano wire, like in the case of type fittings - singa letter, is assembled a number of elements and eventually being shaped by hot pressing on a apparatus as that which is commonly called " pedal mainly two forms heated, steam for example, between which the elements to shaping a pressure controlled by pedal. In the case of caps of simple form, by for example, the device may use three elements: the tower and the bottom of the cap, and the edge: hats more complicated, can carry out to assembly a tens of elements. After the pressing, is disguised the armature externally and internally and, interfering with - the proposal will and finally fixing the trim on the armature by gluing or stitching and is terminated by a pressing "pedal" (that still, may to per - hot-bonding ;. The present invention simplifies considerable in the manufacture of these articles. The it has been found that said requesting based fabrics polyvinyl alcohol have, in some suitable - ditions will identify further away, - store PLAS properties such ticks, that tone may by stamping, with a "pedal" conventional example, obtain directly an armature in its final shape, although - it has strong curvatures, from a panel textile such as it exits the knitting or weaving machine. Of plastic properties can be obtained sufficient by using wires, fibers or bristles alcohol based polyvinyl using a woven or knitted weave appropriate. It was known products exhibiting rigid shaped similarly, using texti - the made of materials having industrial applications in the field of plastics, such as polyvinylchloride. But it is surprising that the textiles based on polyvinyl alcohol, categorized as non-material plastic, are likely larger deformations to the stamping, without breakage or damage wires or bristles while the fittings like conventional textile cannot withstand such distortions and break, whereby tone utilizes, in known methods, to frames of multiple components assembled. On the other hand, a proper choice of armor panels titers and wires or bristles for the armature achieves qualities of plasticity during manufacture and stiffness in use particularly excellent. Further, by selecting certain grades of polyvinyl alcohol, it is possible, during the pressing clothing after obtaining a remarkable bonding between armature and trim. The applicant was able to perceive an affinity very marked between wires or bristles based on polyvinyl alcohol and packings containing polyacrylic or polyvinyl chloride, which gives the assembly a cohesiveness and exceptional strength while maintaining the necessary flexibility and resiliency. The applicant has found further that the results it is possible to very satisfactory with bristles or wires of more than 20 Tex and preferably between 50 and 200 denier, containing at least 50 For understanding the technical features and advantages of the present invention, going in describing exemplary embodiments, with the explicit understanding that they are not limiting as to their mode of implementation and applications that may be compounded into. the mesh deforms without causing breakage or damage; then covers the armeture externally and internally with suitable textile elements, and assembling the whole with stitching or gluing: it can be done using conventional adhesives or better cold, hot upon another change "pedal". With certain qualities polyvinyl (barely acetalized, whose less 25% hydroxyl groups are acetalized for example) and textile clothing (polyacrylonitrile and polyvinyl chloride, in particular) can be dispensed with bonding, hot pressing to impart cohesion of assembly. Thus is terminated by one or more passages to the "pedal", cut the edge of the item then coated using a via for example. Moves on to the "pedal", is disguised, which are adhered to the "pedal", cut the edge and the substrate is covered, wherein bonding is carried out with a conventional glue. In these two examples, obtained articles having excellent resistance regarding their shape, the armature provides the desired stiffness while maintaining flexibility and elasticity such that after deformation, the article returns almost instantaneously to its shape first. It should be noted that so far, we could not obtain the conventional textile-shaped by pressing, stamping and deep as is the case in the present invention, because, as attained a slight bends, the armature breaks or deteriorates so préhibitive. This suitable types of hats, brassieres, reinforcing members (shoulder, stiffeners for petticoats, shoes, masks, and so on); it is possible to use the armature alone or dress with fabrics, felts, papers or cardboards, leather or skin, and the like, or more generally of natural materials, artificial or synthetic. Finally, it should be noted that mixtures may be employed more types of polyvinyl alcohol (acetalized or not, heat treated or not) without departing from the scope of the present invention, resulting in a wide range of very interesting properties. Further, that use blends of polyvinyl alcohol and other fibers, yarns or natural bristles, artificial or synthetic. ABSTRACT 1° method for manufacturing textile articles having good strength properties and a rigid configuration, characterized in that the preform is hot, pressurized, a textile element formed of bristles or wires of more than 20 denier, consisting of at least 50% by weight of textile based on polyvinyl alcohol. 2° method for manufacturing textile articles characterized by the fact that like a textile reinforcement according to 1 degrees, then it is disguised with other textiles, fibrous materials, of hides or skins, natural, artificial or synthetic. 3° method for manufacturing textile articles characterized by gluing on a skin over an armature formed according 1° 2° or hot and under pressure. 4° method for manufacturing textile articles according 3° characterized in that the adhesion is performed in the absence of any paste, with a reinforcement fiber-containing polyvinyl alcohol having less than 25% of its hydroxyl groups acetalized. 5° method for manufacturing textile articles according to one of the paragraphs, characterized by the fact that the polyvinyl alcohol fibers are blended with other fibers, yarns or natural bristles, artificial or synthetic. 6° method for manufacturing textile articles according to one of the paragraphs, characterized by the fact that is utilized several types of textiles based on polyvinyl alcohol. 7° method for manufacturing textile articles according to one of the paragraphs, characterized in that at least one type of textile based on polyvinyl alcohol has more than 25% of its hydroxyl groups acetalized. 8° textile articles and especially hats, soutiensgorge, shoes and reinforcing elements made according to the methods of one of the paragraphs.
