Definitions

  • the present invention relates to the use of a copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent, and a fabric care product containing such a copolymer for reducing repulping of textiles or improving the removal of stains from textiles.
  • the invention also relates to a process for finishing textiles with a soil release protective layer and thus to a process by which the re-soiling of textiles can be reduced and / or the removability of soiling from textiles can be improved.
  • DE 101 525 308 A1 describes for this purpose the use of polymers of polyisocyanates and polymeric polyols. Furthermore, DE 10 2007 013217 A1 describes anionic soil release polyesters which consist of terephthalic acid, sulfoisophthalic acid (poly) alkylene glycol and a nonionic end group.
  • the soil-release agents known in the art either exhibit high selectivity for a particular soiling, meaning that only one particular type of soil, for example, only oil-based soils, or only pigments or other more hydrophilic soils, are removed or unfolded Range of action only on a certain type of tissue, for example, only on polyamides or on cotton-based tissues.
  • NIPAM N-Isopropylacrylamide
  • the N-isopropylacrylamide units contained in the copolymer are very well suited to and applied to different types of fabrics, such as cellulose-based fabrics (cotton), polyamide fabrics, polyester fabrics, blended fabrics, and the like forming a kind of protective layer or protective film which prevents unimpeded access of soiling to or into the tissue and thus prevents or effectively reduces or even prevents soiling or re-soiling.
  • the methacrylic acid units in the copolymer facilitate removal of stains from or from the fabric due to the high hydrophilic content.
  • the methacrylic acid units also promote film formation on the fabric, so that a so-called soil-release protective layer can be uniformly formed on the surface of the fabric.
  • a comprehensive "protective cover" of the textile fabric is promoted by the sterically demanding chains of N-Isopropylacrylamidein whatsoever and methacrylic acid units, so that unimpeded access of soiling to or into the tissue is prevented or at least significantly reduced.
  • the methyl groups in the methacrylic acid units also provide for a certain hydrophobic portion of the copolymer and thus also for hydrophobic soiling, such as oils, fats and Like, not at first penetrate into the tissue, but are intercepted on the surface, so that a washing out of soiling is very easy.
  • the copolymer used according to the invention is distinguished by high hydrophilic but also lipophilic fractions, so that further soiling of different types, ie lipophilic soiling, such as, for example, fats, waxes or oils, and also hydrophilic soiling, such as, for example, pigments and the like, diminished or even prevented or removed very easily.
