  • the invention relates to a laminate made of a textile
  • Such products are e.g. in the manufacture of textiles namely clothing or tents
  • Water vapor is created, for example because there are many people in the tent who are sweating, or if water vapor is generated in some other way.
  • the object of the invention is therefore to provide a laminate which is able to absorb suddenly larger amounts of water vapor, e.g. It is better to drain sweat outwards It is also an object of the invention to provide a material which can be produced in a simple, economical manner and which is good
  • the water vapor permeable waterproof film can in principle consist of any synthetic polymer that gives the film sufficient water vapor permeability while being water impermeable. These include films made of polytetrafluoroethylene, polyetherimide esters such as those e.g. are described in European Patent No. 0 322 777, and polyether amides, polyether urethanes and the like.
  • films which are composed of a synthetic polymer based on copolyether esters i.e. Polymers derived from longer chain polyglycols, short chain glycols, e.g. with 2 to 4

  • the fibers that make up the fleece are permanently hydrophilic.
  • the fibers are preferably fibers made of synthetic polymers. In principle, all synthetic polymers are suitable here which are inherently hydrophilic or in the case of corresponding ones
  • Treatment has achieved permanent hydrophilicity.
  • This permanent hydrophilicity can be achieved by incorporating appropriate additives, which are the polymer
  • hydrophilic polyester fibers As described in German patent application P 27 55 341.9.
  • Hydrophilic fibers are also available from hydrophobic fibers, provided that they are given the appropriate permanent finish. This can be done, for example, by coating it with a film of hydrophilic material. It is important that the hydrophilicity is permanent, ie that the textile does not lose its hydrophilicity even if the wearer sweats a lot, and if it is washed frequently. Hydrophilic fibers made from a polymer based on copolyether esters are particularly suitable, it being particularly advantageous if both the water-vapor-permeable film and the hydrophilic fibers consist of copolyether esters which have the same or only slightly modified chemical composition.
  • Permanently hydrophilic fibers that can adsorb water when high or high are particularly suitable
  • Moisture is present, e.g. as a result of profuse sweating, which, however, releases the water again by desorption as soon as the ambient humidity has decreased.
  • nonwovens made of fibers based on copolyether esters are preferred, it has proven to be particularly advantageous if these fibers are processed to form a nonwoven in a mixture of hydrophobic fibers, in particular polyester fibers, and then used according to the invention to build up the laminate.
  • Mixtures with a small proportion such as about 5% are already suitable, with fractions of 15-25% (weight percent) being preferred. However, higher proportions such as 50% can be used.
  • Laminates according to the invention is the polymer from which the waterproof, water vapor permeable film and / or the permanently hydrophilic fibers are formed, in whole or in part, a copolyether ester, in which at least 70 mol% of the dicarboxylic acid used is 2,6-naphthalenedicarboxylic acid or its ester-forming equivalents and in which at least 70 mol% of the diol used has a small molecular weight of 1.4 -Butanediol or its ester-forming equivalents and the sum of the molar percent of the
