Definitions

  • the subject of the present invention is the use, in a composition for the care of articles made of textile fibers ("textile care"), in particular made of cotton, colored in particular, of at least one nonionic polysaccharide, as agent to prevent the degradation of these articles, to protect the colors of said articles and / or to provide them with anti-crease and / or softening properties.
  • textile care in particular made of cotton, colored in particular, of at least one nonionic polysaccharide
  • This degradation of the fibers leads to the formation of fibrils on the surface of the textile which finally gives a loss of brightness of the colored textiles. This degradation also induces a decrease in the resistance of the textile which has the extreme can lead to tearing of the tissues.
  • This degradation of textiles can be evaluated quantitatively either by a loss of colors of colored textiles or by a decrease in the breaking energy of the textile. It is usually necessary to carry out 10 to 20 cumulative machine washes to perceive this type of degradation.
  • Machine washing machine washing that systematically involves a spin operation also leads to a crumpled cloth that is accented during the drying, in particular by the formation of inter-fiber hydrogen bonds. An ironing operation is therefore necessary to obtain a presentable appearance of the laundry.
  • WO98 / 39401 discloses in particular the use of aminosilicone-type compounds as a softening and color-protecting agent in compositions for washing textiles in an aqueous medium.
