Definitions

  • the present invention refers to a method to manufacture awning fabrics.
  • US 2001/0031590 A1 discloses awning fabrics which are made from polyester filament yarn (continuous filament yarn) and/or polyester monofilament yarn.
  • the invention of said document has as its object to create awning fabric that has the lowest possible weight per unit area while providing good UV stability and weather resistance.
  • the European patent application num. 1355001 discloses an awning fabric which is formed by weaving, at a high density, high-bulky and texturised polyester filament yarns and then by treating uniformly the inner and outer surfaces of the resulting fabric with a coating solution of polytetrafluoroethylene.
  • the awning fabrics disclosed in these patents have in common that all of them are manufactured with polyolefine yarns obtained from cut fibres, joined by the conventional spinning or ring process, and that the composition of the polyolefinic plastic material used comprises always at least two polymeric components with different melting point; as for example, polypropylene and polyethylene.
  • the aim of the present invention is to solve the mentioned disadvantages by developing a manufacturing method of awning fabrics from continuous filament yarn with a single polymeric component of the polyolefin group, offering the advantages that will be described below.
  • the method of the present invention refers to awning fabrics with warp yarns and weft yarns involving the steps of weaving said warp yarns and said weft yarns with a density over 16 warp yarns per centimetre and 10 weft yarns per centimetre, and treating the fabric by immersion with a water-repellent product, and is characterised in that prior to the weaving step, warp yarns and weft yarns are prepared following the steps of:
  • UV stabiliser it means a product which, when admixed with a thermoplastic resin, selectively absorbs UV rays.
  • the fabrics of the present invention manufactured from continuous filament yarns of a single polymeric component of the polyolefin group, have presented a texture, rigidity and inscription effects optimal to be used in awnings. Furthermore, said fabrics present the advantages which are described below, respect to the fabrics for awnings with polyolefin yarns, described in the state the art.
  • Fabrics of polyolefin obtained by the method of the present invention are very suitable for manufacturing awnings since they have, respect of other polyolefin fabrics of continuous filament known in the state of the art, at the same time, an optimum resistance to wetting, water penetration and bleaching caused by the sunlight.
  • said only polymeric component is polypropylene.
  • the step which involves texturing the warp or weft yarn allow to achieve a natural fibre look of the fabric.
  • step b) a step which involves twisting the weft or warp yarn to make the weaving easier is carried on.
  • the step of texturing is carried on a step which involves twisting the weft or warp yarn.
  • the warp yarn is textured to achieve a natural fibre look, and, at the same time, the weft yarn is twisted to make the yarn weaving easier.
  • the extruded yarn has between 30 and 340 filaments, so that a good texturing of the yarn is carried on.
  • the fabric has 30 warp yarns per centimetre and 15 weft yarns per centimetre, to create a woven structure dense enough to achieve a good resistance to water penetration.
  • the water-repellent product is a fluoro-acrylic copolymer, so that a water penetration resistance between 10 and 80 cm of water column is achieved.
  • the UV stabiliser comprises a Hindered Amine Light Stabiliser (HALS).
  • HALS is a chemically reactive substance that scavenge free radicals, created by the UV light induced degradation of the polymer matrix, which prevents the physical degradation of said polymer.
  • said plastic material comprise between 0.1% and 10% of pigments, to obtain the desired colour.
  • said UV stabilizer product comprises, furthermore, an UV absorber of high molecular weight, which protects from the sun the pigments with comprises the plastic material, and prevents the decolouration of the fabric.
  • the method of manufacturing awning fabrics starts with the preparation of material of polypropylene granulate, adding 0.8% of stabilizer product and 3% of a combination of pigments based on polyolefin.
  • the stabilizer product comprises a mix of a Hindered Amine Light Stabilizer (HALS) and an UV absorber of high molecular weight, preferably of the benzotriazole group.
  • HALS Hindered Amine Light Stabilizer
  • the method of manufacturing continuous filament warp yarn and continuous filament weft yarn starts, with the extrusion method. Following that, it continues with the texturing process for the warp yarn and the twisting process for the weft yarn.
  • the extrusion process of the warp yarn and the weft yarn starts with the insertion of the polyolefinic plastic material, comprising the UV stabiliser and the pigments, into an extruder and it continues with the application of an extrusion temperature of 230°C.
  • the melted plastic is driven through an isolated conduct up to the spinning head of the extruder, where it is forced by the pressure pumps through the spinplates.
  • the spinplates have 0.3 mm-diameter holes. The number of holes determines the yarn filaments, due to be 120.
  • the yarn is air-cooled at 15°C. Afterwards, 1% of spinning oil is applied.
  • the yarn is then stretched to orientate and align the molecular chains, thus achieving an acceptable tenacity. It is stretched by means of hot cylinders (120°C) and/or by means of ovens (140°C).
  • the stretch ratio is from 1 to 4.
  • the yarn suffers a process of shrinking of 5% by means of hot cylinders and/or by means of ovens.
  • the amount of melted material going through the spinplates along with the stretch and shrinkage ratio determines the yarn coarseness or count, of preferably 440 dtex.
  • the cone winding of the yarn is carried on by means of a winding machine.
  • the wound warp yarn is textured to achieve a natural fibre look by air pressure.
  • the method involves putting the yarn into water to moisten it, and immediately inserting it into a hole under air pressure, in a determined direction, which curls the filaments and achieves the texturing effect.
  • the air pressure rating in this hole is 11 bar. Once textured, the yarn is wound again.
  • the extruded yarn is inserted into a double-twist twisting machine applying an 80 turns per metre torsion.
  • the warp yarns are warped in a beam and then placed on the back of the loom, in the right shape to achieve the necessary design.
  • the weft yarns are placed on a bobbin holder and they are then inserted into the loom perpendicularly to the warp yarns.
  • the final fabric obtained with a specific weaving machine for this case has a woven structure of 15 weft yarns per centimetre and 30 warp yarns per centimetre. This weaving density is enough to achieve a good water penetration resistance with the subsequent finishing treatment.
  • the finishing process involves treating the fabric with a water-repellent product. This process starts with the fabric washing with an anionic product at 90°C for 6 hours to remove the remains of spinning oil. After that, a water wash is carried on and finally a moister-proofing of the fabric with a fluoro-acrylic copolymer in emulsion.
  • the application dose of this copolymer is 4% for a initial 50% fabric humidity.
  • the treated fabric is dried in an oven at 130°C for 2.5 minutes.
  • the finishing guarantees a fabric enduring a 20 cm water column, according to UNE EN 20811 Regulation, and having a high resistance (ISO5) to wetting, according to UNE EN 24920 Regulation.
  • the described process results in obtaining a fabric of continuous filament yarn of polypropylene which, unlike the other polyolefinic fabrics with continuous filament yarns known in the state of the technique, meets all quality standards established for awning fabrics, especially regarding its water penetration and wetting resistance.
  • the annexed table shows the results of a comparative test made with two pieces of polyolefin fabric of continuous filament yarn.
  • Fabric A is a sample of the fabric obtained by the method of the present invention, whereas fabric B is a current state of the art polyolefin fabric suitable to be applied to upholstery and outdoor furniture covering.
