Definitions

  • the hygienic textile equipment is increasingly attracting the interest of man-made fiber manufacturers and textile suppliers.
  • the products available on international markets are given an antimicrobial property, in particular by spinning the active ingredients into the polymer matrix.
  • the controlled release of active substances from microcapsules which have been incorporated into the corresponding textile fibers is also known.
  • Possible toxic and allergic reactions of the previously used chemical agents, generally biocides and the like, are problematic.
  • Newer approaches therefore have the goal of developing skin-compatible yarn finishing, for example based on chitosan (D-glucosamine).
  • the present invention thus relates to a method for temporarily finishing textiles, in particular synthetic textiles, in which a hydrogel is applied to the textile surface, in particular the fibers of the textiles.
  • This treatment step is generally followed by a process step in which the textile fibers treated in this way are dried. Drying is preferably carried out under normal pressure and at ambient temperature, in particular at room temperature. However, drying can also be carried out at higher temperatures (e.g. in a tumble dryer). The hydrogel particles are not destroyed during drying, ie no forces are exerted on the hydrogel particles during the drying process.
  • hydrogels in particular in the form of aqueous hydrogel dispersions, are used which are able to absorb water by swelling.
  • the method according to the invention can be applied to synthetic textiles, preferably synthetic articles of clothing, since these generally have no or only a very low water absorption capacity or are only slightly hydrophilic.

Abstract

L'invention concerne un procédé pour apprêter, notamment temporairement, des textiles, en particulier des textiles synthétiques, comme par exemple, des vêtements textiles. Selon le procédé, un hydrogel est appliqué sur la surface des textiles, notamment sur leurs fibres, puis les textiles ainsi traités sont séchés. Selon les applications souhaitées, l'hydrogel peut être chargé de substances actives ou d'agents constituants.
