Definitions

  • This invention relates to an improved felted product.
  • a further object of the invention consists in the provision of a felt which does not lose its properties during the fulling treatment.
  • Synthetic fibers suitable for the production of especially against alkali and acid is greater than felts according to this invention may be spun.
  • Suitable starting materials for the fibers are the polymeric anhydrides of fi-aminohexanoic acid and the similar polymerisates of e-caprolactam, as well as condensation products containing components having a carbon chain interrupted by hydrophii groups for instance ether groups, such as ppdiaminodiethylether or condensation products with relatively short structural units for instance lA-butylenediamine.
  • the fibers may be obtained according to the usual melt spinning processes. Especially suitable are fibers which are obtained by cutting or stamping cold drawn or cold rolled ribbons. In this case the cutting edges may be rovided with a wavy or toothed structure.
  • Example 1 A felt consists of per cent of a coarse wool of a single titer of 9 deniers and 40 per cent of a fiber of polymeric e-caprolactam of an individual titer of 8 deniers of a tenacity of 340 grams per deniers and an elongation before breaking of 60 per cent.
  • the felt obtained by fulling at 60 C. in a bath containing sulfuric acid may be dyed uniformly and fastly with suitable acid wool dyestuffs.
  • a felt consists of '70 per cent of animal hair of a titer of 25 deniers and 30 per cent of a synthetic fiber of the polymeric anhydride of e-aminocaproic acid.
  • the felt obtained by acid falling and by impregnating with a synthetic latex is suitable for technical purposes, for instance as an intermediate base for apparatus and machines or for such commodities as for instance felted cloths and hats.
  • a sulfuric acid fulled felt comprising a mixture of animal fibers and cold drawn fibers of a. synthetic linear polyamide, said felt impregnated with synthetic latex.
