Definitions

  • the present invention relates to a household practicable process for ironing and / or wrinkle reducing equipment of textiles made of cellulosic material and the use of certain polymers obtainable from norbornene derivatives to reduce crease tendency and to facilitate the ironing of textiles made 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 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.
  • Shape memory polymers are polymeric stimuli-responsive materials that can alter their shape under the influence of external stimuli such as light, magnetic field or heat.
  • the permanent shape is usually determined by crystallization or glass transition. The action of mechanical forces can change the shape of the shape memory polymer. As the temperature is raised above a certain switch temperature, these polymers return from their temporarily altered form to their permanent shape.
  • the invention therefore relates to a method which can be carried out in the household for the crease-reducing and / or ironing-facilitating finishing of textiles made of cellulose-containing material by contacting with a shape memory polymer which has a switch temperature in the range from 20 ° C. to 60 ° C., especially from 40 ° C to 58 ° C, and subsequently raising the temperature of the fabric above the glass transition temperature of the polymer thereon, for example by using a commercial iron.
  • the cellulosic materials from which the textiles to be treated are made include cotton, regenerated cellulose fibers such as Modal or Lyocel, and blended fabrics of cotton or regenerated cellulose with other fabrics commonly used in clothing such as polyester and polyamide.
  • the textile After placing the shape memory polymer on a textile of cellulosic material, such as cotton, and then raising the temperature above the glass transition temperature of the shape memory polymer, the polymer, and thereby the textile on which it is placed, gets its permanent shape.
  • the textile is in a desired smooth shape, which, as well as the mentioned temperature increase, for example, by ironing can be achieved.
  • the textile is ironed following treatment with said polymer with a standard household iron.
  • the tension created when the fabric is worn, combined with the cooling that occurs when the fabric is deposited, can lead to the formation of a so-called temporary shape of the polymer and thus of the textile that supports it, in which the textile may have wrinkles.
  • the washing of the fabrics possibly combined with the subsequent use of a dryer, raises the temperature of the fabrics above the switch temperature of the polymer, thereby returning to the permanent shape of the shape memory polymer and thus of the fabric bearing it.
  • the measures of the invention considerably reduce the creasing of textiles made of cellulosic material compared to the untreated starting textiles or a treatment with an aminopolysiloxane.
  • the assessment of the wrinkle-free effect can be done by measuring the crease recovery angle (KEW) according to DIN 53890: 1972.
  • the shape memory polymers used according to the invention preferably have a glass transition temperature in the range from 0 ° C to 100 ° C, in particular from 10 ° C to 50 ° C.
  • the textile of cellulosic material at temperatures in the range of 10 ° C to 100 ° C, in particular from 20 ° C to 60 ° C, brought into contact with said polymer.
  • the textile is then heated to a correspondingly higher temperature.
  • the implementation of the invention can be carried out, for example, by bringing textiles made of cellulosic material into contact with an aqueous preparation containing said polymer.
  • This can be done in the context of a normal washing process, which is carried out with the help of a household washing machine or by hand can be done.
  • the said polymer in aqueous liquor is preferably used in the rinsing step, ie after the actual washing step, but can also be used in the washing step.
  • Said polymer may be part of detergents or laundry aftertreatment agents commonly used in such washing processes, such as fabric softeners.

  • said polymer can also be part of a laundry care product, which can be present in particular as a liquid spray product, which, after dilution with water or preferably undiluted, applied to a textile of cellulose-containing material, in particular sprayed on, without having to follow a washing process or the application must be preceded by a washing process immediately.

Abstract

L'invention a pour objectif un procédé à usage domestique permettant de réduire la tendance d'un tissu cellulosique à base de coton ou autre à se froisser. Cet objectif est atteint par mise en contact du textile avec un polymère à mémoire de forme qui présente une température de transition dans la gamme de 20°C à 60°C, et par augmentation ultérieure de la température du tissu au-dessus de la température de transition vitreuse du polymère placé sur le tissu.
