Definitions

• the present invention relates to the utitisation of a composition for providing the textile fiber with good hydrophilicity, an absence of yellowing and a soft hand feel, that is to say softness properties.
• the document US 4,409,267 describes for example the use of a mixed polyorganosiloxane carrying on the one hand primary (or secondary) amine function (s) substituted for example by residues containing an OH or O-group; alkyl, and secondly function (s) polyoxide (s) alkylene (s) as additive of a composition for the treatment of textile materials.
• the document EP 546 231 discloses another approach via the use of a polyorganosiloxane bearing a unit (s) of formula Si - (CH 2 ) y - (OCH 2 ) y ' - CH (OH) CH 2 --N (CH 2 CH 2 OH) 2 where y is between 2 and 8 and y 'is 0 or 1.
• EP 659 930 discloses silicone-based fabric softeners comprising from 2 to 1600 silicon atoms, carrying one to one hundred sterically hindered amine units and optionally other units such as, for example, alkyl radicals of 5 to 20 carbon atoms or radicals ( CH2) p-COO-R.
• FR 2,745,825 discloses silicone fabric softeners carrying at least one sterically hindered amine unit and at least one polyether group of the formula (CH 2 ) n - (OCH 2 CH 2 ) ⁇ (OCH 2 CHCH 3 ) ⁇ - OR.
• Another advantage of the use according to the present invention stems from the fact that it can be implemented with an industrially easy and storage stable polyorganosiloxane.
• Another advantage of the use according to the present invention comes from the easy treatment of the composition containing the polyorganosiloxane according to the invention for its application to the materials to be treated.
• the silicone oil used in the context of the invention does not require in particular the presence of other functions to provide hydrophilic properties to the treated textile material. However, if it is desired to obtain a hydrophilicity greater than that intrinsic to the material before treatment, the silicone oil used may contain other functions promoting this property.
• the polyorganosiloxane of formula (I) used is linear.
• the functional group V of the polyorganosiloxane of formula (I) used is chosen from the functional groups of formula (II).
• the treatment process may be carried out on woven, non-woven or knitted form materials.
• the fibers of these materials are at least partially hydrophilic, and this hydrophilicity is preserved after treatment with silicone according to the invention, notwithstanding the hydrophobic nature of its skeleton.
• the at least partially hydrophilic materials may consist in particular of or based on cotton, linen, wool, viscose, rayon, hemp, silk or a mixture of these materials. These materials may be optionally mixed with other low or non-hydrophilic materials such as polyester (eg cotton-polyester blend), keratin, polypropylene, polyethylene, polyurethane, polyamide, cellulose acetate.
• composition containing the polyorganosiloxane can be prepared in many forms: liquid, gaseous or solid.
• a liquid preparation of the composition it will advantageously be aqueous in the form of solution, dispersion or emulsion.
• the composition is prepared in the form of an aqueous emulsion.
• the composition according to the process of the invention may also be used in solution in an organic solvent.
• aqueous emulsions are generally based on a mixture of oil and water, and are prepared according to standard methods well known to those skilled in the art using surfactants.
• the emulsions can be done by the so-called direct methods or by inversion. Their production is easy and does not require the use of equipment with high stirring speed. Normal speed stirring apparatus may be used.
• the aqueous emulsions prepared according to the invention preferably contain between 20 and 90% by weight of water relative to the total mass of the constituents of the emulsion.
• the emulsions prepared according to the invention are preferably diluted to contain between 95 and 99.5% by weight of water, relative to the total weight of the emulsion.
• the application of the polyorganosiloxane according to the invention to the materials to be treated can be carried out in very different forms. Applications can be made by immersion, coating, spraying, printing, padding, or any other existing means.
• the fabric when the fabric is treated with an aqueous composition containing a polyorganosiloxane according to the invention, said fabric is subjected to a heat treatment to quickly expel water in the form of steam.
• the amount of polyorganosiloxane deposited on the material to be treated varies according to the constitution and manufacture of said material.
• the applications of the compositions and in particular aqueous emulsions on the treated materials are carried out so that the increase in weight of the treated material does not exceed 0.1 to 20% by weight relative to the weight of the material before treatment.
• the best results have been observed with a quantity of polyorganosiloxane of between 0.1 and 2% by weight relative to the weight of the material to be treated.
• the previously defined polyorganosiloxanes may be prepared by different methods; for example: distribution or hydrosilylation.
• oils are tested in application in the form of an aqueous emulsion and the measurements of hydrophilicity, non-yellowing and evaluation of the feel are carried out according to the tests described below.
• the evaluation of the yellowing is carried out by measuring the color of the fabric (white cotton terry cloth at the beginning) after impregnation with the silicone oil and heat treatment for 9 minutes at 150 ° C.
• the color measurement is made on a Sprectrophotocolorimeter ACS Sensor It sold by the company Datacolor.
• the measurement conditions are the use of illuminant D65, reproducing daylight. From the measurement of the color of the tissue sample, the instrument calculates the values of different indices of white and yellow, among which we use the CIE white index.
• the cotton terry cloth After applying the oil, the cotton terry cloth is dried in ambient air for 24 hours. After 1 minute heat treatment at 150 ° C, the fabric is placed 24 hours in conditioning (23 ⁇ 2 ° C, 50 ⁇ 5% relative humidity).
• the polyester-cotton fabric (50/50) undergoes a heat treatment of 5 minutes at 170 ° C. It is then conditioned for 24 hours (23 ⁇ 2 ° C, 60 ⁇ 5% relative humidity).
• the hydrophilicity measurements are given by the TEGEWA test in which the absorption time of a drop of water deposited on the surface of the fabric is measured. The shorter the time, the more the tissue is hydrophilic.
• the silicone oils of the emulsions tested E1 to E7 have the following structure:
• the emulsions are prepared using an inversion emulsification method, and have the following composition: 20 g of silicone oil tested, 8 g of surfactant (C 13 E 6 fatty alcohol), an amount of glacial acetic acid stoichiometrically necessary for the neutralization of the amine and the complement at 100 g with water.
• 20 g of silicone oil tested 8 g of surfactant (C 13 E 6 fatty alcohol), an amount of glacial acetic acid stoichiometrically necessary for the neutralization of the amine and the complement at 100 g with water.

• the evaluations were carried out on textiles treated with 0.6% by weight of silicone oil.
• the emulsions are applied to the fabric by padding.
