Description

  • This invention relates to processes for wrinkleproofing cellulosic textiles, wrinkleproofing finishes, the use of the finishes and also textile treatment compositions, solid and liquid laundry detergent formulations and fabric care rinse compositions. [0001]
  • Cellulosic textiles are given easy care properties by treatment with condensation products of urea, glyoxal and formaldehyde, for example. The finish is applied during the manufacture of textile materials. Softening compounds are frequently further applied with the finish. Thus finished textiles are less wrinkled and creased, easier to iron and softer and smoother after laundering compared with untreated cellulose textiles. [0002]
  • WO 92/01773 discloses the use of microemulsified aminosiloxanes in fabric conditioners to reduce wrinkling and creasing during the laundering process. In addition, the use of aminosiloxanes is said to facilitate ironing. [0003]
  • WO 98/4772 discloses a process for pretreating textile materials by applying a mixture of polycarboxylic acid and a cationic softener to the textile materials. Wrinkle control is obtained as a result. [0004]
  • EP-A 0 300 525 discloses fabric conditioners based on crosslinkable amino-functionalized silicones that impart wrinkle control or an easy-iron effect to textiles treated therewith. [0005]
  • WO 99/55953 discloses fabric wrinkle control compositions. They comprise lubricants, shape retention polymers, lithium salts and optionally further ingredients such as softeners, ionic and nonionic surfactants, odor control agents and bactericides. The formulation is preferably applied to the textile material by spraying. [0006]
  • EP-A 0 978 556 describes a mixture of a softener and a crosslinker component having cationic properties as a fabric wrinkle and crease control composition and also a method of wrinkleproofing textiles. [0007]
  • WO 00/24853 describes a fabric softening formulation which provides wrinkle reducing benefits to the treated textiles. The wrinkle reducing agents used are preferably modified silicones such as aminopolydimethylsiloxane-polyalkylene oxide copolymers or sulfated or sulfonated vegetable oils such as sulfated castor oil. [0008]
  • It is an object of the present invention to provide a further process for wrinkleproofing cellulosic textiles and also further finishes for wrinkleproofing such textiles. [0009]
  • We have found that this object is achieved by a process for wrinkleproofing cellulosic textiles, which comprises treating the textiles with a finish and drying the treated textiles, wherein the finish contains one or more water soluble or water dispersible polysiloxane-containing polymers obtainable by free radical polymerization of [0010]
  • (a) from 10 to 99% by weight of [0011]
  • (a1) from 90 to 100% by weight of singly ethylenically unsaturated monomers and [0012]
  • (a2) from 0 to 10% by weight of multiply ethylenically unsaturated monomers [0013]
  • the sum total of (a1) and (a2) being 100% by weight [0014]
  • in the presence of [0015]
  • (b) from 1 to 90% by weight of silicone derivatives containing polyalkylene oxide [0016]
  • the sum total of (a) and (b) being 100% by weight. [0017]
  • The invention also provides a wrinkleproofing finish for cellulosic textiles that contains these polymers. [0018]
  • The polymers used according to the invention are soluble or dispersible in water. When polymerized from monomers having neutralizable radicals, their neutralized form is soluble or dispersible in water. [0019]
  • Useful polymerizable monomers (a) are preferably ethylenically unsaturated monomers. It is possible to polymerize a monomer alone or a combination of two or more different monomers. [0020]
  • The monomers can be polymerized by all customary methods of free radical polymerization. These can be for example solution polymerization, emulsion polymerization, inverse emulsion polymerization, suspension polymerization, inverse suspension polymerization or precipitation polymerization. In the case of a solution polymerization, the solvents used can be water, customary organic solvents or the silicone derivatives of the invention themselves. [0021]
  • The polymerization is effected in the presence of initiators which form free radicals under the polymerization conditions. Useful free radical forming initiators include all customary peroxy and azo compounds, for example peroxides, hydroperoxides and peroxy esters such as for example hydrogen peroxide, dibenzoyl peroxide, di-t-butyl peroxide, t-butyl hydroperoxide, t-butyl perpivalate and t-butyl peroxy-2-ethylhexanoate, and also azo compounds, for example 2,2′-azobis(2-amidinopropane) dihydrochloride, 2,2′-azobis(2-methylbutyronitrile) and 2,2′-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride. It will be appreciated that initiator mixtures or the familiar redox initiators can also be used. The polymerization temperature is preferably in the range from 40 to 100° C. It will be appreciated that the polymerization can also be carried out outside the stated temperature range, in which case the polymerization is carried out in pressure tightly sealed apparatus at higher temperatures, for example at from 120 to 140° C. The initiators are used in the customary amounts, i.e., in amounts of for example 0.1-5 percent by weight, based on the monomers to be polymerized. [0022]
  • Useful ethylenically unsaturated monomers include singly unsaturated or mixtures of singly unsaturated with multiply unsaturated monomers. The C—C double bond can be mono-, di-, tri- or tetrasubstituted. [0023]
  • The monomers (a) of the polysiloxane-containing polymers of the present invention can comprise from 10 to 99% by weight, preferably from 50 to 95% by weight, particularly preferably from 70 to 90% by weight of all components (a) and (b). [0024]

  • Examples of useful monomers (a1) are acrylic acid and its salts, esters and amides. The acrylic acid salts can contain any desired nontoxic metal ion, unsubstituted or substituted ammonium ion as counterions. [0029]
  • The esters can be derived from linear or branched C[0030] 1-C40- or C3-C40-alcohols or carbocyclic C3-C40-alcohols, from multiply functional alcohols having from 2 to about 8 hydroxyl groups such as ethylene glycol, hexylene glycol, glycerol and 1,2,6-hexanetriol, from aminoalcohols or from ether alcohols such as methoxyethanol, ethoxyethanol or polyethylene glycols.

  • This invention also provides for the use of the polysiloxane-containing polymers obtainable from (a) and (b) in finishes for wrinkleproofing cellulosic textiles. Finishes are any liquid formulations which contain the polysiloxane-containing polymers in dissolved or dispersed form for application to the textile material. The finishes of the invention can be present for example as finishes in the narrower sense in the manufacture of textiles or in the form of an aqueous washing liquor or as a liquid textile treatment. Useful solvents include for example water, alcohols such as methanol, ethanol and propanol, THF or mixtures thereof. It is possible for example to treat textiles with the finish in the course of their manufacture. Textiles which have not been adequately finished, if at all, may be treated with a textile treatment that contains the polysiloxane-containing polymers for example before or after home laundering, for example during ironing. But it is also possible to treat the textiles with polysiloxane-containing polymers in the main wash cycle or after the main wash cycle in the care or softening rinse cycle of the washing machine. [0095]
  • The present invention also provides for the use of the polysiloxane-containing polymers obtainable from (a) and (b), in the manufacture of textiles, textile treatment before and after laundering, laundry main wash cycle, laundry conditioning rinse cycle and ironing. Different formulations are needed in each case. [0096]
  • The treatment before or after laundering may utilize a textile treatment composition which, as well as a polysiloxane-containing polymer in dissolved or dispersed form, contains a surfactant. In this treatment, the cellulosic textiles are for example sprayed with the polysiloxane-containing polymers with an add-on which is generally in the range from 0.01 to 10% by weight, preferably in the range from 0.1 to 7% by weight, particularly preferably in the range from 0.3 to 4% by weight, based on the weight of the dry textile material. But the finish may also be applied to the textile material by dipping the textiles into a bath which contains generally from 0.1 to 10% by weight, preferably from 0.3 to 5% by weight, based on the weight of the dry textile material, of a polysiloxane-containing polymer in dissolved or dispersed form. The textile material is either dipped only briefly into the bath or else allowed to dwell therein for a period of from 1 to 30 min for example. [0097]
  • Cellulosic textiles which have been treated with the finish either by spraying or by dipping are if necessary squeezed off and dried. Drying may take place in air or else in a dryer or else by subjecting the treated textile material to hot ironing. The finish becomes fixed on the textile material in the course of drying. The best conditions in each case are readily ascertainable by experimentation. The temperatures for drying, including ironing, are for example in the range from 40 to 150° C. preferably from 60 to 110° C. For ironing, the cotton program of the iron is suitable in particular. Textiles treated with the polysiloxane-containing polymers in dissolved or dispersed form according to the above-described process exhibit an excellent level of wrinkle and crease resistance that is durable to multiple laundering. There is frequently no longer any need to iron the textiles. The textiles thus treated additionally possess fiber and color protection. [0098]
  • The invention also provides a textile treatment composition comprising [0099]

The aforementioned basic monomers may also be used in quaternized form. [0107]
  • A pretreatment formulation to be applied to the textile material by spraying may additionally include a spraying assistant. In some cases, it can also be of advantage to include in the formulation alcohols such as ethanol, isopropanol, ethylene glycol or propylene glycol. Further customary additives are scents, dyes, stabilizers, fiber and color protection additives, viscosity modifiers, soil release additives, corrosion control additives, bactericides and preservatives in customary amounts.

  • A detailed description of the laundry detergent ingredients mentioned is found for example in WO 99/06524 or WO 99/04313 and in Liquid Detergents, Editor: Kuo-Yann Lai, Surfactant Sci. Ser., Vol. 67, Marcel Decker, New York, 1997, p. 272-304. [0155]
  • The concentration of the polysiloxane-containing polymers in the wash liquor is for example in the range from 10 to 5 000 ppm, preferably in the range from 50 to 1 000 ppm. Textiles treated with the polysiloxane-containing polymers in the main wash cycle of the washing machine not only wrinkle substantially less than untreated textiles, they are also easier to iron, softer and smoother, more dimensionally and shape stable and, because of their fiber and color protection, look less used, i.e., exhibit less fluff and fewer knots and less color damage or fading, after repeated washing. [0156]
  • The polysiloxane-containing polymers may be used in the softening or care rinse cycle following the main wash cycle. The concentration of the polysiloxane-containing polymers in the wash liquor is for example in the range from 10 to 5 000 ppm, preferably in the range from 50 to 1 000 ppm. The rinse liquor may if desired include ingredients typical for a fabric conditioner or refresher. Textiles treated in this way and then dried on the line or preferably in a tumble dryer likewise exhibit a very high level of crease resistance that is associated with the positive effects on ironing that were described above. Crease resistance can be substantially enhanced by briefly ironing the textiles once after drying. The treatment in the softening or care rinse cycle also has a favorable effect on the shape retention of the textiles. It further inhibits the formation of knots and fluff and suppresses color damage. [0157]

  • f) from 0 to 99.85% by weight of water. [0164]
  • said components a) to f) adding up to 100% by weight. [0165]
  • Useful further silicones b) include the abovementioned silicones. [0166]
  • Preferred cationic surfactants b) are selected from the group of the quaternary diesterammonium salts, the quaternary tetraalkylammonium salts, the quaternary diamidoammonium salts, the amidoamine esters and imidazolium salts. These are preferably present in an amount of from 3 to 30% by weight in the fabric care rinse compositions. Examples are quaternary diesterammonium salts which have two C[0167] 11- to C22-alk(en)ylcarbonyloxy(mono- to pentamethylene) radicals and two C1- to C3-alkyl or -hydroxyalkyl radicals on the quaternary nitrogen atom and, for example, chloride, bromide, methosulfate or sulfate as counterion.
  • Quaternary diesterammonium salts further include in particular those which have a C[0168] 11- to C22-alk(en)ylcarbonyloxytrimethylene radical bearing a C11- to C22-alk(en)ylcarbonyloxy radical on the central carbon atom of the trimethylene group and three C1- to C3-alkyl or -hydroxyalkyl radicals on the quaternary nitrogen atom and, for example, chloride, bromide, methosulfate or sulfate as counterion.
  • Quaternary tetraalkylammonium salts are in particular those which have two C[0169] 1- to C6-alkyl radicals and two C8- to C24-alk(en)yl radicals on the quaternary nitrogen atom and, for example, chloride, bromide, methosulfate or sulfate as counterion.

  • Amidoamino esters are in particular tertiary amines bearing a C[0171] 11- to C22-alk(en)ylcarbonylamino(mono- to trimethylene) radical, a C11- to C22-alk(en)ylcarbonyloxy(mono- to trimethylene) radical and a methyl group as substituents on the nitrogen atom.
  • Imidazolinium salts are in particular those which bear a C[0172] 14- to C18-alk(en)yl radical in position 2 of the heterocycle, a C14- to C18-alk(en)ylcarbonyl(oxy or amino)ethylene radical on the neutral nitrogen atom and hydrogen, methyl or ethyl on the nitrogen atom carrying the positive charge, while counterions here are for example chloride, bromide, methosulfate or sulfate.

    • Finishing of Fabric Samples
  • The finish used was a 1% by weight solution of the polymers according to examples A to J. [0193]
  • Cotton fabrics having the size reported in Table 1 and the basis weight of 160 g/m2 were sprayed on both sides with the finishes as per examples A-J in such a way that the add-on was 2%, based on the particular weight of the dry textile material, and then hot pressed while still slightly moist. [0194]
  • The fabric samples thus treated and, for comparison, untreated fabric samples of the same size were washed in the presence of ballast fabric with a liquid laundry detergent at 40° C. in an automatic domestic washing machine (load in the range from 1.5 to 3.0 kg) and then tumble-dried. A standard washing program and a standard drying program (respectively 40° C. colored wash and the cupboard dry program) were used. After drying, the sheetlike fabric samples were visually rated on the lines of AATCC test method 124, where a rating of 1 indicates that the fabric is highly wrinkled and has many creases and the rating of 5 is awarded to wrinkle- and crease-free fabric. The fabric samples pretreated with the finishes A, B and C received ratings between 2 and 3.5. In contrast, the untreated fabric samples each received a rating of 1. [0195]
