Definitions

  • Backing nonwovens are known in the industry for a variety of applications. The the essential thing is that they have the desired properties for permanent wear of the each product are sufficient. For this reason, these nonwovens in general made from staple fibers and then chemically and / or mechanically consolidated.
  • the intimate mixing of the fleece with a binder is under chemical consolidation to understand that after a heat treatment process the fibers of the Fleece firmly bonded together.
  • the fleece can also contain thermoplastic binding fibers are added after the melting process under the influence of heat Glue non-melted fibers point by point.
  • the ones that can be produced with these processes Backing fleeces have the required strength, but they are expensive to manufacture because of the necessary binders or the necessary melt fibers.
  • EP-A-0 259 692 discloses a fleece made of continuous fibers by means of hydrodynamic Solidify needling and provide it with a wetting agent. These products are intended for the improved absorption of liquids and have a better textile handle.
  • EP-A-0 363 254 to name, after which the non-woven fabric made of continuous fibers with heat-bonded strengthened Resin dots are provided for the production of heat-adhesive interlinings.
  • the invention has for its object a method and according to the method to develop a desirable product with which a high-strength fleece such as in particular carrier fleece can be produced, which for z.
  • B. Betumen webs has the required strength, but is not provided with any binding agent or binding fiber.
  • the invention provides that continuous filaments immediately after their manufacture to a uniformly thick fleece placed on an endless sieve, then needled hydrodynamically for production a high-strength fleece, and this hydrodynamically needled continuous fiber fleece is used as a carrier fleece without the use of binders, which is followed by the entire surface a useful coating is applied.
  • the filing of the continuous fibers can be done with today's technology can be done safely such that a substantially uniform Strength can be achieved in the two surface dimensions.
  • this fleece these filaments are then injured with the water needling in the third Dimension shifted, hooked together, this creates the desired high strength, without the expensive and disadvantageous binders in the further processing of the nonwoven to be needed.
  • the fleece is still highly breathable and can because no wetting agents are used in the production of the consolidated nonwoven, better penetrated with a full-surface wear layer. It can even compared to the method according to the prior art, a higher proportion of betumen can be entered into the fleece without losing the elasticity of the fleece.
  • the intimate mixing of the betumens by the existing ones is also advantageous Pores of the fleece, which has consequences for the non-cleavability of the fleece in particular at low temperatures.
  • the useful coating can e.g. B. be a betumen coating, or this Backing fleece serves as a matrix sheet for later tufting finishing.
  • These fleeces can also be made from endless PETP fibers because of that not only high-strength, but also thermostable nonwovens can be achieved.
  • a 45 g / m 2 nonwoven made of endless PE fibers was needled hydrodynamically for consolidation and had a strength of 133 N / 5 cm in the longitudinal direction and 109 N / 5 cm in the transverse direction with an elongation of 68 and 75%. This results in a longitudinal strength of 3.0 N / 5cm per g / m 2 . This strength is sufficient to z. B. to offer the basis as Betumenbahn.
  • a 145 g / m 2 nonwoven made of endless PE fibers was needled hydrodynamically on both sides for strengthening and obtained a strength of 530 N / 5 cm in the longitudinal direction with an elongation of 75%. This results in a longitudinal strength of 3.7 N / 5cm per g / m 2 .
