Definitions

  • the present invention relates to the use of amino group-containing polymer and certain oxidizing agent for minimizing curling and ease of ironing textiles made of cellulosic material, as well as a household practicable process for ironing and / or wrinkle reducing finishing of cellulosic material.
  • Textiles made of cellulose such as cotton or cellulose regenerated fibers (for example Modal or Lyocel) have from the consumer's point of view positive properties in terms of wearing comfort.
  • cellulose regenerated fibers for example Modal or Lyocel
  • a major disadvantage of these textiles is the slight creasing during wear, after washing and drying. This tendency to wrinkle is due to the swelling of the cellulose fibers and their low elastic restoring forces ("bounce") after deformation.
  • Formaldehyde-free crosslinking processes for cellulose are also known, for example from US 2004/0043915 A1 a crosslinking process which is carried out with the aid of hydroxyl-bearing polymer and polycarboxylic acids, in particular butanetetracarboxylic acid (BTCA). From the article by CMWelch in Textile Research Journal, 1988, 480-486 the use of tetracarboxylic acids for crosslinking cellulose fibers is known. These formaldehyde-free approaches of cellulose crosslinking with the aid of polycarboxylic acids may, from a toxicological point of view, be suitable in principle for home use.
  • BTCA butanetetracarboxylic acid
  • ion pair bonds are exploited for the crosslinking of the cellulose.
  • Cotton usually has a content of carboxyl groups of about 10 ⁇ 6 mol / g.
  • the cellulose can be treated with chloro or bromoacetic acid to increase the number of its carboxyl groups.
  • Interaction of the carboxylated cellulose with polycations, such as cationized chitosan, can result in ionic crosslinks that reduce the tendency to crease. Without the carboxylation, the effect is too small and carboxylation of cotton textiles with haloacetic acids is not considered for home use.
  • the invention therefore relates to the use of an oxidizing agent which oxidizes vicinal OH groups in the anhydroglucose ring of the cellulose to carbonyl groups, in particular of periodate, and amino group-containing polymer for minimizing the tendency of creases of textiles made of cellulose-containing material.
  • Another object of the invention is the use of an oxidizing agent which oxidizes vicinal OH groups in the anhydroglucose ring of the cellulose to carbonyl groups, in particular periodate, and amino group-containing polymer to facilitate the Bügeins of textiles made of cellulosic material.
  • Further objects of the invention are methods which can be carried out in the household for ironing-facilitating and / or wrinkle-reducing finishing of textiles made of cellulose-containing material by contacting with an oxidizing agent which oxidizes vicinal OH groups in the anhydroglucose ring of the cellulose to carbonyl groups, in particular of periodate, and one amino group-containing polymer.
  • the cellulosic materials from which the textiles to be treated are made include cotton, regenerated cellulosic fibers such as Modal or Lyocel, and blended fabrics of cotton or cellulose regenerated fibers with other apparel-based materials such as polyester and polyamide.
  • the contact with oxidizing agent and polymer containing amino groups can be carried out either simultaneously or sequentially, wherein in the second-mentioned alternative, the oxidizing agent is used in front of the polymer.
  • the textile is ironed subsequent to treatment with said oxidant and said polymer with a standard household iron.
  • the measures of the invention significantly reduce the creasing tendency of textiles made of cellulosic material compared to the untreated starting textiles or exclusive treatment with an aminopolysiloxane.
  • Oxidizing agents which are preferred according to the invention include the alkali metal and ammonium periodates, for example potassium periodate and sodium periodate.
  • Peroxygen-based bleaches or whitening systems for use in detergents such as H2O2 or peroxoalkanoic acids, for example peracetic acid, phthalimidoperacycaproic acid, and peroxononanoic acid are not suitable for oxidizing vicinal OH groups in the anhydroglucose rings of the cellulose to carbonyl groups ,
  • KEW crease recovery angle
  • amino-containing polymer used in the context of the invention has, in addition to the plurality of amino groups, no further nucleophilic units, such as, for example, hydroxyl or carboxyl groups.
  • Amino group-containing polymers which are preferred according to the invention are aminopolysiloxanes, polyvinylamines and polyalkyleneimines, such as polyethyleneimines, and mixtures of these.
  • Aminopolysiloxanes preferred in the context of the present invention have the general formula
  • R is straight-chain or branched or cyclic C 1 - to cis-hydrocarbon radicals
  • R 2 is R or one of the groups -R 3 -NHR 4 or -R 3 -NR 4 -R 3 -NHR 4 in which R 3 is a straight-chain or branched or cyclic divalent O to Cis hydrocarbon radical and

  • the hydrocarbon radicals may optionally contain an aliphatic double bond.
  • alkenyl radicals such as vinyl, allyl, 5-hexenyl, E-4-hexenyl, Z-4-hexen-1-yl, 2- (3-cyclohexenyl) -ethyl and cyclododeca-4,8-dienyl.
  • Preferred radicals having aliphatic double bond are vinyl, allyl, and the 5-hexenyl radical.
  • at most 1% of the hydrocarbon radicals R contain one double bond.

Abstract

L'invention vise à réduire la tendance au froissement d'un textile en coton ou une autre matière cellulosique. À cet effet, le textile est mis en contact avec un agent oxydant, qui oxyde les groupes OH vicinaux dans le cycle anhydroglucose de la cellulose en groupes carbonyle, et avec un polymère contenant des groupes amino, puis le textile est éventuellement repassé.
