Definitions

  • the invention proposes the use of solutions which contain polyamide resins on the one hand and polymers bearing acid groups on the other hand, for coating polyamide fibers, before the final processing.
  • fibers are understood to mean both continuous fibers and also fiber cuts, fiber composites, yarns, pulp and the like, as well as textile fabrics, be they woven, knitted, knitted or in some other way, for example connected as non-wovens.
  • fibers are coated in technology with surface treatment agents, for example epoxy resin preparations or else with other resins. This is described, for example, in US-A-4,557,967 and US-A-4,652,488.
  • surface treatment agents for example epoxy resin preparations or else with other resins.
  • the associated improvements in the adhesion of the fibers in the matrix are not yet sufficient.
  • the treatment of the fibers with epoxides in some cases leads to embrittlement, so that the fibers treated in this way can break or split open in subsequent textile processing steps, such as knitting or weaving; furthermore the water absorption by the fiber is increased.
  • DE-A-35 04 804 describes a hot melt adhesive made from polyamides based on dimerized fatty acids, aliphatic amines and modifying additives on the one hand and copolymers of ethylene on the other hand, with an additional 5 to 95% by weight, based on the total mixture, of a copolymer of ethylene , the inner anhydride of an ethylenically unsaturated dicarboxylic acid and optionally (meth) acrylic acid esters and / or vinyl esters are contained.
  • the copolymers preferably consist of 50 to 90 wt .-% ethylene, 5 to 30 wt .-% (meth) acrylic acid ester of aliphatic linear or branched primary C1-C18 alcohols and 2 to 30 wt .-% of the inner anhydride of a polymerizable Carboxylic acid.
  • a further object of the invention is to provide coated polyamide fibers, in particular aromatic polyamide fibers (aramid fibers), which have better processability in knitting and weaving processes, combined with higher resistance to material fatigue.

In contrast to untreated fibers, no wear was observed. The image of the knitwear was uniform. Furthermore, no deposits were formed in the knitting machine. This means that the surface treatment agents according to the invention significantly improve the interchangeability of aramid yarns.
