Definitions

  • the present invention relates to a process for packaging textile materials to give them a pleasant touch by hand, that is to say softness, at the same time as good hydrophilicity.
  • US-A-4 409 267 describes the use of a mixed polyorganosiloxane carrying a part of primary amine function (s) or of secondary or tertiary amine function (s) (s) substituted (s) for example by residues containing an OH or O-alkyl group, and on the other hand of alkylene polyoxide function (s) as additive of a composition for the treatment of textile materials.
  • GB-A-2 201 696 relates to a method for treating textile materials using a polyorganosiloxane carrying quaternary ammonium function (s) which does not have a substitution containing an OH or O-alkyl group.
  • EP-A-0 459 822 describes homogeneous and transparent detergent compositions comprising a polyorganosiloxane with secondary or tertiary amine function (s) substituted for example by residues containing an OH group, said group silicone being used in mixture with a softening agent based on a quaternary ammonium salt.
  • An advantage of the process according to the present invention is that it makes it possible to obtain textile materials having the two properties (softness and hydrophilicity) mentioned above.
  • Another advantage of the process according to the present invention is that it makes it possible to obtain textile materials exhibiting slight yellowing.
  • Another advantage of the process according to the present invention stems from the fact that it can be implemented with a polydiorganosiloxane of easy industrial preparation and stable in storage.
  • the polydiorganosiloxane used can optionally comprise monoorganosiloxy units RSi 1.5 and / or SiO2 units, but if they exist, these units are in the proportion of at most 2% relative to the number of diorganosiloxy units R2SiO, the meaning of R having been specified above.
  • the composition containing the polydiorganosiloxane defined above is an aqueous composition, in the form of an emulsion.
  • the nitrogen of the group X defined above can be salified, for example with an organic acid such as acetic acid.
  • R represents a C1 to C6 alkyl group.
  • polysiloxanes previously defined can be prepared in a similar manner to those described in American patent US Pat. No. 3,389,160, but using diethanolamine in place of dimethylamine.
  • the method according to the present invention can be implemented on any woven or knitted fabric and even on those made of nonwoven.
  • the fibers used for the production of these fabrics can be in particular cotton, polyester, polyamide, viscose, polyacrylate, wool, linen, cellulose acetate, as well as elastomeric fibers. It is of course possible to use mixtures of fibers.
  • this fabric is then subjected to a heat treatment in order to rapidly expel the water in the form of vapor.
  • an aqueous composition for example an emulsion
  • the amount of polysiloxane deposited on the treated fabric corresponds to an amount of between 0.1 and 1% by weight relative to the weight of the dry fabric treated.
  • the polyester yarn is coated (by a known technique) with a solution at 3% by weight of the polysiloxane with groups X previously defined in trichloroethane.
  • the coated wire is then dried continuously at 180 ° C. in a hot air oven at a speed of 200 m per minute (200 m / min).
  • a wire is thus obtained on which the deposit of polydiorganosiloxane product corresponds to 0.5% by weight relative to the weight of the dry wire.
  • the wire is then stored for 48 hours at 22 ° C, at 65% relative humidity.
  • the friction coefficient of the wire obtained is then determined on the ROTHSCHILD F device. Meter at the speed of 1 cm / min (centimeter per minute).
  • the test used to evaluate the hydrophilicity of the fabrics treated according to the method of the present invention is a test consisting in depositing a piece of treated fabric (25.4 x 25.4 mm) parallel to the surface of the distilled water located in a beaker and to measure the time between the deposition of this fabric on the water and the beginning of its descent into the water. This test is called "sinking test" in English.
  • the diethanolamine is condensed on an organosiloxane oil of average formula: measuring 36.6 meq / 100 g in glycidyl function.
  • a product is thus obtained whose average formula corresponds to the above product, but in which Z has been replaced by :-( CH2) 3-O-CH2-CH (OH) -CH2-N (C2H4OH) 2.
  • the emulsion is brought to pH 6 with acetic acid.
  • the products having the trade names TERGITOL TMN 10, TERGITOL TMN 6 and RENEX 30 are widely marketed surfactants known to those preparing emulsions.
  • TERGITOL TMN 6 comprises as active product a trimethylnonanol comprising 6 oxyethylene units.
  • TERGITOL TMN 10 comprises as active product a trimethylnonanol comprising 10 oxyethylene units.
  • RENEX 30 manufactured by ICI, comprises as active product a tridecylol comprising 10 oxyethylene units.
  • Example 3 the product prepared according to Example 3 is the one that best responds to the desired application, that is to say a soft feel and good hydrophilicity, when the fabric is cotton.
