Definitions

  • the invention relates to the support of tufted carpets in which the threads which constitute the surface of use of the carpet are stitched.
  • tuft support in the following description designated by "tuft support”.
  • area of use of the carpet will also be designated by “velvet”: consequently, the term velvet cannot be interpreted restrictively as designating certain structures of velvet, but must include all the structures carpeted surfaces.
  • velvet threads the threads making up the surface area for carpeting.
  • tufted carpets are obtained using several tens of needles aligned across the width of the carpet which stitch through the prefabricated tuft support the threads which will form the surface of use .
  • the velvet yarn With the velvet yarn, the construction of the surface of use is a qualitative factor of the carpet on which depend its performances of use, its esthetics and its longevity.
  • the tightening in the lengthwise direction is expressed by a number of points (ie velvet tufts or loops) per linear meter.
  • points ie velvet tufts or loops
  • the spacing between the needles which prick the thread in the tuft support conditions the tightening in the width direction.
  • tuft support Another major quality factor of the carpet is the tuft support. Indeed, an efficient velvet yarn, a rigorous velvet construction or a resistant tuft support cannot by themselves make a good carpet.
  • the quality of a tufted carpet is the result of a balanced combination of all the components that work together, strengthen, add their forces to multiply the effects. This is why tuft supports are required to be able to satisfy both the process and the finished product constraints.
  • the qualities of the tuft support also condition the use performance of the finished product because it contributes to its solidity and longevity. This is why, it is highly desirable that the tuft support is both sufficiently rigid and non-deformable to maintain the flatness of the carpet and that its dimensional stability is sufficient under the combined action of temperature, humidity and usage constraints.
  • woven or non-woven fabrics of synthetic material are widely used as a tuft support: the material usually used is either a woven polypropylene or a non-woven polyester, the latter being the most used despite its creep .
  • Said tuft support is a woven or non-woven fabric constructed with glass threads sheathed using a vinyl plastisol, said woven or non-woven fabric then being covered with a resin (I) which adheres to the vinyl plastisol but is not compatible with this vinyl plastisol.
  • the glass strands of this tuft support retain a certain degree of mobility during tufting.
  • tuft support requires from 25% to 45% of tufting force in addition to that necessary for tufting an open woven of glass threads covered with a vinyl coating, after heat treatment. (merger).
  • such a support may be toxic as soon as it is subjected to high temperatures (due to a fire for example) because the vinyl plastisol recommended in this patent is a polyvinyl chloride.
  • the invention aims to remedy the drawbacks of the prior art and in particular to simply produce a tuft support whose high mechanical characteristics on the one hand, facilitate the tufting operation as well as the other operations necessary for the manufacture of 'a tufted carpet and on the other hand, guarantee to the tufted carpet performance of use and a long longevity.
  • the subject of the invention is a tuft support in which the threads which will form the working surface of a tufted carpet are fixed by tufting, characterized in that it consists of a non-desensitized woven fabric, practically non-deformable under normal conditions of use, and consisting of glass strands impregnated with a polymeric material, in order to coat a large number of the filaments constituting each glass strand and therefore to substantially limit, during tufting , the direct contacts between on the one hand, the threads forming the woven glass and on the other hand, the needles of the tufting loom and the threads useful for achieving the surface of use.
  • the tufting operation using the tuft support according to the invention did not lead to premature wear of the velvet yarn.
  • the tuft support according to the invention can therefore easily undergo the tufting operation and the subsequent operations necessary for the manufacture of quality tufted carpet.
  • Unbleached glass woven fabrics that is to say glass woven fabrics which have not undergone a heat and / or chemical treatment to remove the size of the wire and the sizing of the warp, are suitable for the invention. Indeed, desensed glass woven fabrics do not have sufficient mechanical properties for use as a tuft support.
  • tuft support Another important parameter for the tuft support lies in the non-deformability of the glass woven under normal conditions of use, that is, in other terms in the weaving of glass strands which must be tightened (as opposed to an open weaving revealing days visible to the naked eye and allowing displacements of the network formed by the glass strands). Indeed, to technically allow tufting, it is important that the woven glass is almost non-deformable under normal conditions of use, that is to say that it mainly has sufficient dimensional stability in traction, without scuffing or displacement of the network formed by glass threads under the action of tufting needles.
  • the structure of the threads used for the glass woven can be very diverse: one can choose either simple threads, twisted or not, as assembled ones (for example assembled ones comprising at least two simple threads assembled by twisting) or twists or many other structures provided that the woven fabric, which includes them, is sufficiently non-deformable under normal conditions of use.
  • single threads or assembled threads or twists are used which are preferably twisted with a slight twist of the order of 10 turns / m or greater, or even better, with a twist of the order of 20 turns / m or higher.
  • the maximum number of glass threads or glass filaments per cm of woven fabric is not critical.
  • the diameter of the filaments forming the glass wire is of the order of 9 microns.
  • the tuft support is made from a woven glass weave fabric which guarantees an effective hold of the network of threads and makes the woven glass almost non-deformable under normal conditions of use.
  • the tuft support consists of a non-desensized glass woven fabric, of threads impregnated with a polymeric material in order to protect the glass threads from tufting needles and to make the woven fabric more manageable during tufting.
  • the impregnation operation can also be carried out on the glass yarn before weaving, or on the glass woven. It has been found that this operation makes it possible to coat a large number of filaments constituting each glass wire: hence an impregnation at the heart of the wire.
  • these baths contain at least one slip agent in order to further facilitate the passage of the needles through the glass woven treated during tufting.
  • the slip agent is selected from the compounds known to provide a slip effect by not remembering that those which do not interfere with operations subsequent to tufting: thus, an important selection criterion of the slip agent lies in the fact that it must hardly affect the adhesion capacity of the tuft support with the other components. carpet foundations.
  • baths preferably contain about 0.1 to 1% by weight of slip agent.
  • the treated glass woven fabric After leaving the bath, the treated glass woven fabric is generally wrung out and then dried.
  • the polymers suitable for the invention are the polymers capable of undergoing the transformation cycles induced by the manufacture of the tufted finished product without undergoing degradation.
  • the polymers chosen must not change state under the temperature (ie around 150-200 ° C) and humidity conditions of this manufacture.
  • polyurethanes styrene-butadiene resins
  • acrylic resins acrylic resins or copolymers of the monomers useful for the manufacture of the abovementioned polymers.
  • the glass woven fabrics treated in accordance with the invention achieving the best performance as a tuft support, have, before tufting, preferably a tensile strength in the transverse direction at least equal to 175 daN for 5 cm according to ISO 4606, while a polyester nonwoven has, before tufting, a tensile strength in the transverse direction significantly lower and generally around 32 daN per 5 cm (according to ISO 4606).
  • glass woven fabrics treated in accordance with the invention having before tufting a tensile strength in the transverse direction of less than 175 daN per 5 cm (according to ISO 4606), can also constitute satisfactory tuft supports.
  • the polymeric material represents a weight per m 2 of glass woven material which is preferably chosen to be greater than or equal to 4 g, more preferably still to be greater than or equal to 6 g.
  • the weight of polymeric material per m 2 of glass woven material is preferably less than 30 g, more preferably less than or equal to 25 g, or even better, less than or equal to 20 g.
  • the carpets using the tuft support according to the invention have good behavior under the action of temperature, humidity and other constraints of use.
  • the joints between the tiles tufted according to the invention remain invisible over time.
  • the use of the tuft support according to the invention improves the flame resistance properties of the finished products.
  • the glass woven exemplified is a woven fabric composed of glass threads whose filaments have a diameter equal to 9 microns, having in warp and weft the same title which is 68 tex for a texture 17.5 x 12.5 (which means 17.5 warp threads per cm and 12.5 weft threads per cm).
  • the weight per square meter of this unbleached glass cloth is equal to 210 g.
  • the glass cloth impregnated with acrylic resin can be used as a tuft support.
