Description

The present invention relates to compositions and a method for treating textiles in an aqueous Bath, such as the final rinse after a washing process for the purpose of improvement different properties of the textile.

The US-PS 33 76 161 describes according to claim 1, a means for Impregnating fibrous material containing this material To provide abrasion resistance and as constituents

• (1) a first quaternary ammonium chloride,
• (2) a narrow molecular weight dimethylpolysiloxane of 69,000 to 71,000 (which corresponds to a viscosity of 11 x 10 ^-3 to 16 x 10 ^-3 m² / s) and
• (3) a second quaternary ammonium chloride of the formula (R₆) (R₇) (R₈) (R₅NH ·CO ·CH₂) N-Clworin R₅ is a C₁₆-C₁₈ hydrocarbon group,
  R₆ is a hydrocarbon group substituted by hydroxyl and alkoxy groups and R₇ and R₈ are hydrocarbon groups substituted by hydroxyl groups.

In the fibrous material, which with the impregnating agent is to be treated, is packaging material, d. H. Corrugated, fiberboard, paper and other fibrous Packaging materials, and the coating with the impregnating agent should cause that with the coated  Packaging material packed items, eg. Eg refrigerators, not be scratched by the packaging material and that no abrasion of the packaging material on the packaged Objects settles.

It has been found several years ago that textiles a softer grip can be imparted by a treatment in a dilute solution or dispersion made of certain cationic quaternary ammonium derivatives and there are rinse additives for this purpose been brought to the market.

The present invention surprisingly becomes made possible, significant additional benefits obtained by using an unusual combination of textile treatment  or conditioning agents used becomes. These benefits can be used individually or in combination following: easing of ironing, awarding antistatic properties, conferring a more pleasant Handle of the textiles, improved release of dirt. It It seems that the finding of a "lighter Ironing "on a combination of at least three factors may be attributed, namely, that less wrinkles to eliminate that the wrinkles easily eliminable are (for example, using a lower ironing pressure) or that they can be eliminated more completely and that less effort is needed to get the iron to move along the textiles. A "pleasant Handle "can be judged throughout by experienced professionals although it is not easy, in words the sensation or describe the combination of sensations due to the more comfortable grip. Antistatic Properties and improved release of dirt facilitate the achievement and maintenance of dirt-free tissues.

The combination of the agents according to the invention sees this Presence of both a cationic compound with a or a plurality of long-chain alkyl groups as well as a silicone, as defined in more detail below, before.

Silicones are used to obtain various benefits have been used, for example as water repellents and as "ironing aids", but they are usually on the textiles during manufacture or during completion of clothing in the form of relatively concentrated Dispersions or solutions of silicones either by procedures such as padding or by spraying been applied. In other words, after the Prior art treatments performed a treatment with relatively concentrated, z. B. 2-3 wt .-% and more, Dispersions or solutions of silicones to the object to to ensure that some silicone on the surface of the  Textiles remains. Often, especially for water repellent Treatment, the textiles were subsequently treated with catalysts to crosslink or cure effect of the silicone. If normal, commercially available Silicones on textiles from dilute aqueous systems they are not sufficiently substantive d. h., there is insufficient silicone in the silicone-containing contain diluted residual liquid in the textile material, to cause significant effects, and therefore are the beneficial effects of the silicone on the textile material very much reduced or missing altogether.

It has now surprisingly been found that, then, if a silicone, even at very low concentrations, is introduced into a bath, the particular textile substantive containing cationic fabric softening agents, and silicone and plasticizers are used in certain proportions, the silicone together with the fabric softener the Tendency to migrate to the surface of the textile material and there is substantive and enriched. Thus a very desirable overall effect can be achieved, the both advantages in terms of softening and such additional advantages as mentioned above. These latter can be varied by varying the silicone become.

The present invention thus becomes a composition created for textile treatment, which a aqueous dispersion which

silicone component

The silicone component is an aqueous emulsion of a predominantly linear polydialkyl or alkylaryl siloxane in which the alkyl groups have from 1 to 5 carbon atoms and may be fully or partially fluorinated. Suitable silicones are polydimethylsiloxanes having a viscosity at 25 ° C. in the range from 1 × 10 ^-4 to 20 × 10 ^-2 m² / s, preferably not more than 12 × 10 ^-2 m² / s and expediently in the range from 10 × 10 ^{-4 . 4} to 50 · 10 ^-4 m² / s. Fluorinated silicones which have a viscosity of at least 1 x 10 ^-4 m 2 / s are also useful.

The combination of a textile-substantive quaternary Ammonium textile softening compound and a silicone of The above type improves the substantivity of the latter considerably. It is believed that this increased substantivity due to a "carrier" effect, through the positively charged fabric softening molecules with the silicone molecules and cause that they migrate to the textile surface. However, experiments have shown  that the distribution of this combination on the textile material not quite optimal, d. h., that certain areas of the textile material receive a high concentration of silicone, while on others, if at all, very little it is present.

However, it has been found that the ionic charge characteristics of the silicone used in the combination in determining both the extent of deposition and also the uniformity of the distribution of the silicone and therefore for the properties of a textile material treated therewith are important.

This is illustrated in the following table, in the adsorption of various silicone polymers on cotton textile material from a 0.2% by weight aqueous solution of the silicone was measured as a function of time.

It can be seen that silicones, the cationic Character, an increased tendency for deposition demonstrate.

Silicones, which result in the achievement of advantages the handle of textiles proved valuable have predominantly linear character and are preferable Polydialkylsiloxane in which the alkyl group usually Methyl is. Such silicone polymers often become commercial by emulsion polymerization using a strong acidic or strongly alkaline catalyst in the presence of a nonionic or mixed nonionic-anionic Emulsifier system produced.

When combining with the cationic fabric softener show anionic or nonionic emulsified Silicone polymers tend to coalesce in dilute aqueous solution due to the attraction between the negatively charged or uncharged emulsifier and the positive charged fabric softener. In creating a Silicone emulsion that has a similar charge as the fabric softener However, there would be a tendency towards Reduction of this effect, and a further reduction due to the tendency of the charged silicone droplets, to repel each other, to be expected.

Thus, in the context of the present invention, the Silicone component of a silicone cationic character, which
