Description
COMPOSITION FOR CLEANING CARPETS, INCLUDING FITTED
CARPETS, CURTAINS AND COVERING FABRICS AND/OR FOR
FACILITATING THE REMOVAL OF STAINS AND DIRT THEREFROM
A subject matter of the present invention is an aqueous composition comprising at least one sulfonated copolyester for cleaning carpets, including fitted carpets, curtains and covering fabrics at least partially made of hydrophobic synthetic polymer, in particular of polyester or polyamide, very particularly of polyamide, and/or for facilitating the removal of stains and dirt (soil release) therefrom. Another subject matter of the invention is a process for cleaning carpets, including fitted carpets, curtains and covering fabrics at least partially made of hydrophobic synthetic polymer, in particular of polyester or polyamide, very particularly of polyamide, and/or for facilitating the removal of stains and dirt (soil release) therefrom by the nonpermanent deposition on these, by spraying, application by hand or application using a cleaning device, of an aqueous composition comprising at least one sulfonated copolyester. It is also targeted at the use, in an aqueous composition for the nonpermanent treatment of carpets, including fitted carpets, curtains and covering fabrics, of at least one sulfonated copolyester as detergent agent and/or as agent which facilitates the removal of stains and dirt (soil release) .
It is known to decrease the viscosity of stable aqueous emulsions of a mixture of at least one nonionic hydrophilic surface-active agent and of at least one nonionic hydrophobic surface-active agent by addition of an optionally sulfonated, terephthalic oligomer or polymer; these emulsions can be used as cleaning composition, for example for cleaning carpets (EP-A-629, 690) .
It is also known to use terephthalic oligomers carrying sulfonated functional groups as antisoiling (soil release) agents in detergent compositions for washing laundry made of polyester or based on polyester (WO 95/32997, WO 92/04433 and US 4,877,796) . The Applicant Company has found that some copolyesters exhibiting sulfonated units are particularly advantageous in aqueous compositions for the nonpermanent treatment of carpets, including fitted carpets, curtains and covering fabrics at least partially made of hydrophobic synthetic polymer, in particular of polyester or polyamide, very particularly of polyamide, as detergent (soil removal) agents and/or as agents which facilitate the removal of stains and dirt (soil release). The term "nonpermanent" means that the active agent only remains temporarily on the fibers or surfaces and can be easily removed, unlike a permanent
(finishing) treatment carried out at high temperature, where the active agent is intended to remain permanently on the fibers or surfaces.

* Ethylene glycol 339 g (5.47 mol)
* Dimethyl 5-(sodiooxy- 104.4 g (0.353 mol) sulfonyl) isophthalate
* Titanium aminotriethanolate 54 ppm of (catalyst) titanium
The medium is subsequently preheated to 180°C and then brought to 220°C over approximately
130 minutes, during which period of time the methanol resulting from the transesterification reaction is distilled off.
The reaction mixture is subsequently heated in order to reach 230°C over 30 minutes. When the
reaction mass has reached this temperature, the gradual introduction of the following charge II is begun:
* Isophthalic acid 11.72 g (0.07 mol)
* Ethylene glycol 67.2 g (0.34 mol)
* Terephthalic acid 56.7 g (1.08 mol) over a period of time of one hour, while maintaining the reaction mass at 230°C. Heating is subsequently continued in order to bring this reaction mass to 250°C over 60 minutes. During this period, a mixture of water and ethylene glycol distils off without retrogradation . A gradual vacuum is applied at this temperature in order to obtain a reduced pressure of 100 mbar over 22 minutes. The reaction mass is then poured. The product is redispersible in water.

"Dirt Devil" vacuum cleaner "Bissel" steam cleaner . "Rug Doctor" steam cleaning concentrate - Preparation of the fitted carpets -
1) The fitted carpet is first of all cleaned from one side to the other, front and rear, using Rug Color detergent diluted according to the manufacturer's instructions (2 oz. per gallon, i.e. approximately 15 g/1), using a Bissel steam cleaning device.
2) After drying, the fitted carpet is cut up into
4" x 4" (approximately 10 x 10 cm2) squares which are marked underneath in order to make sure that all the strands are oriented in the same direction from one square to another in order to obtain similar appearance characteristics (less reflectance) .
3) The fitted carpet samples are subsequently marked in order to indicate the tests and the products.
- Staining-cleaning test - 1) Two tests are carried out for each stain. The reflectance before staining, Rdl, of the fitted carpet samples is measured.
2) The oil stains are produced by using the micropipette; the waxy stains are firstly pressed onto the applicational sponge and subsequently applied to the fitted carpet samples.
The oil stains are applied at a dose of 0.12 ± 0.05 g for each fitted carpet sample inside a 2" x 2" (approximately 5 x 5 cm2) square mask using a spatula. The waxes are applied at a dose by weight of 0.15 ± 0.05 g.
3) The stains are left to dry overnight before cleaning. The reflectance of the stained fitted carpet samples, RD2 , before cleaning is measured. 4) The samples are dried four times (each time for
5 seconds), following the recommendations given on the
label carried by the fitted carpet, using white absorbent paper towels.
5) The samples are subsequently treated by spraying at a distance of 4-6" (approximately 10-15 cm) with 4.0 ± 0.1 g of the following aqueous liquid cleaning product sodium lauryl sulfate 2% sodium polyacrylate 1% propylene glycol 3% . fragrance 0.05% water q.s. for 100% with a pH of 9, to which has been added from 0.25% to
1% of its weight of sulfonated copolymer prepared above . 6) The product is left to stand in order to allow the foam formed to penetrate into the stains.
7) The stains are cleaned by rubbing five times from the top of the stain through the center using a dry white absorbent paper towel; the paper towel is turned over in order to obtain a clean surface and rubbing is carried out a further five times from the bottom of the stain through the center.
8) Stages 5) to 7) are repeated an additional four times for each sample, for a total of five cleaning cycles.
9) The fitted carpets are dried and then vacuumed. The reflectance, Rd3, of the cleaned fitted carpet samples is then measured. The removal of the stains (soil removal), R", is calculated as follows:
Rd2 - Rd3
R' = x 100
Rd2 - Rdl
The results obtained (values of R" in %) are as follows:
