Definitions

  • Awning fabrics are currently preferably made of 1: 1 polyacrylonitrile (PAN) threads in plain weave with the highest possible weft and warp density.
  • PAN polyacrylonitrile
  • the fabrics In order to achieve a stiff handle required for awnings and water and oil repellent properties or sufficient water resistance, the fabrics must be provided with a chemical finish.
  • Melamine-formaldehyde resins are used for the stiff handle and fluorocarbon resins are used for oil and water repellency.
  • PAN fabrics A disadvantage of PAN fabrics is that no suitable way has been found to recycle PAN fabrics. For this reason, the not inconsiderable production waste that arises when assembling the awning fabrics and when cutting edges, as well as the used awnings must be disposed of or incinerated.
  • small amounts of amines are produced during recycling, for example by melting and regranulation, by thermal decomposition of the melamine-formaldehyde resins, which give the regranulate a fish-like odor.
  • the unpleasant smell and, due to the melamine-formaldehyde resin, cross-linked resin particles, so-called gel particles, remain in the regranulate, so that only up to 30% of the regranulate can be reused in a mixture with new goods.
  • EP-B1-0 629 724 describes polyolefin fabrics which, without melamine-formaldehyde resins, give the desired stiff grip.
  • the yarns used here consist of a fiber mixture of PP fibers and low-melting binder fibers, the proportion of the low-melting binder fibers can vary between 1 and 20% by weight.
  • the present invention accordingly relates to recyclable textile fabrics for textile sun protection articles, tarpaulins, tent fabrics, tarpaulin fabrics and the like, which are characterized in that they are made of yarns or twists of polyolefin biconstituent fibers in combination with 0 - 50% by weight in the warp and / or weft direction. % Polypropylene fibers are made.
  • Biconstituent fibers made of PP with different contents of PE and their production are described, for example, in US 4,839,228.
  • the polyolefin biconstituent fibers used according to the invention consist of a finely dispersed mixture of polypropylene and 40 to 60% by weight of a lower-melting thermoplastic which is immiscible with polypropylene.
  • Polypropylene (PP) is isotactic or syndiotactic polypropylene that may contain the usual proportions of atactic PP due to the manufacturing process. It is preferred to use syndiotactic or isotactic PP with the highest possible tacticity and thus the most crystalline polypropylene possible.
  • thermoplastics which are not miscible with PP, z. B. polyethylene, copolyamide or copolyester. Thermoplastics which are immiscible with PP and have a melting point of between about 70 and 150 ° C. are preferably used.
  • Polyethylene (PE) is particularly preferably used as the low-melting thermoplastic.
  • Polyethylene (PE) can be used as "low density polyethylene” (LDPE), "high density polyethylene” (HDPE) and as linear low density polyethylene “(LLDPE).
  • PE is preferably used as LLDPE or HDPE.
  • LLDPE can contain 1 to 20% by weight of at least one ⁇ -olefin alkylene having 3 to 12, preferably 4 to 8, carbon atoms.
  • polyolefin biconstituent fibers made of PP and 40 to 60% by weight of low-melting thermoplastic, which is immiscible with PP, are used to produce the textile fabrics.
  • the proportion of low-melting thermoplastics is preferably between 45 and 58% by weight, particularly preferably between 50 and 55% by weight.
  • the fabrics according to the invention can consist 100% of yarns or twists of biconstituent fibers.
  • the proportion of biconstituent fibers can also be replaced by PP fibers up to 50%.
  • the PP fibers used here can consist of isotactic, syndiotactic and atactic PP, as described above. Iso and syndiotactic PP is again preferably used.
  • the PP and biconstituent fibers used contain customary auxiliaries and, above all, must have high UV stability and color fastness, in particular weather fastness.
  • auxiliaries are, for example, UV stabilizers, thermal stabilizers and pigments.
  • Suitable UV stabilizers are, for example, polymeric HALS ("hindered amine light stabilizers") or mixtures of different HALS stabilizers.
  • Suitable pigments are organic and inorganic pigments which have the required high weather fastness and do not negatively influence the UV stability.
  • yarns or twists are first made from staple fibers or multifilaments which have the required high UV stability, color fastness and weather fastness.
  • auxiliaries described above are added to the polymer during melt spinning.
  • PP fibers and biconstituent fibers with different fiber finenesses or single filament finenesses can be used. Fibers with a titer between 1.5 and 5 dtex are preferred, particularly preferably between 1.7 and 3 dtex.
  • the textile fabric is preferably a woven fabric.
  • PP fibers can be added to the yarns or twists to increase the strength. This can be done in the form in which the yarn already consists of a fiber mixture of PP fibers and biconstituent fibers or the twine in z.
  • double twisting consists of a yarn 100% PP and a yarn 100% biconstituent fiber. After the usual washing of the fabric or the textile fabric to remove the spinning and, if appropriate, twist preparation, the fabric is removed or textile fabrics only with equipment for oil and water repellency. Fluorocarbon resins are preferably used for this.
  • the fabric or textile fabric When the fluorocarbon resin is condensed, the fabric or textile fabric is heated to a temperature above that of the melting point of the lower-melting component of the biconstituent fiber, the biconstituent fibers sticking to one another and to the PP fibers which may be present. After cooling, this leads to the desired stiff grip with good elasticity at the same time.
  • yarns or twists are made from the biconstituent fiber described in warp and weft or only used in warp or weft.
  • a suitable temperature control there are significantly smaller changes in color (especially the depth of color) in the thermal treatment of the tissue compared to the prior art.
  • the occurrence of light streaks in the event of buckling or creasing is largely avoided.
  • Another advantage is that a fabric or textile fabric, while maintaining good recyclability, without the effort of a homogeneous mixture of z.
  • B. PP fibers can be made with PE fibers.
  • the fabrics or fabrics thus obtained are thus particularly suitable for the production of textile sun protection articles, preferably awnings, but also for boat covers, tarpaulins, camping furniture covers and the like.
  • the threads Nm 34/2 and Nm 50/2 made from the ASOTA type FV8817, were used to manufacture the chains.
  • the fabrics were produced on a Sulzer projectile weaving machine in plain weave 1: 1 (30 warp threads / cm, 14.5 weft threads / cm with the twist count Nm 34/2; 36 warp threads / cm and 17 weft threads / cm with the twist count Nm 50/2) .
  • the finished fabrics had the desired stiff grip with good elasticity at the same time.
  • the maximum tensile force according to DIN 53857 was 264 daN / 5 cm in warp and 125 daN / 5 cm in the weft direction and the maximum tensile elongation was 54% and 22%, respectively.
  • the water tightness according to DIN 53886 resulted in 32 mbar.
  • the tissues can be easily regranulated.
  • the regranulate can be used 100% for the production of polyolefin staple fibers.
