  • Patent number: 10465341
    Abstract: The invention relates to a fabric belt for the production of a corrugated cardboard web in a corrugated cardboard machine having several warp layers. In at least one edge region of the fabric belt, a surface of its upper warp layer has at least first regions (21) which consist of first yarns, and second regions (22) which consist of second yarns. The first yarns contain 30% b.w. to 100% b.w. aromatic polyamides, 0% b.w. to 70% b.w. aliphatic and/or alicyclic polyamides and 0% b.w. to 5% b.w. other materials. The total of the polyamides and other materials thus gives 100% b.w. The second yarns contain 50% b.w. to 85% b.w. polyester and/or aliphatic polyamides and/or alicyclic polyamides, 15% b.w. to 50% b.w. cellulose and 0% b.w. to 5% b.w. other materials. The total of the polyesters, polyamides, cellulose and other materials gives 100% b.w.

  • Publication number: 20100304085
    Abstract: A method for manufacturing a non-woven/sheet laminate, involves preparing a sheet having a first and a second side, the sheet being made from a film or foil which is not a non-woven material. A first non-woven layer is disposed on the first side of the sheet and a second non-woven layer is disposed on the second side of the sheet, a visible side of the second non-woven layer having a linting coefficient of less than 2.7 and a sliding coefficient of friction of between 0.35 and 0.75. At least one of the first and the second non-woven layers comprises spunbond and meltblown layers with an outwardly facing spunbond layer. The non-woven/sheet laminate is subjected to a thermal treatment process and associated reduction in length in a flat direction.

  • Publication number: 20080271228
    Abstract: A disposable clothing is used for protection against liquids or microorganisms, in particular for medicine, chemistry or biotechnology. The clothing comprises, in particular a front part and sleeves (20) connected thereto. The clothing (10) is provided with an external layer (12) in the form of a non-woven air-permeable material. A barrier layer which is selected such that it is air permeable but liquid-proof, is applied to at least the side of the external layer (12) which is oriented towards a person wearing the clothing (10). The barrier layer is, at least in places, connected to the external layer. The non-woven material of the external layer (12) is a laminated material comprising spunbond and meltblown layers.
