Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for conditioning textiles and compositions suitable for use in the method.

It is known to condition textiles in order to improve the properties of treated textiles, especially during or immediately after the textile washing process. Typically, this treatment softens the washed textile and improves its hand. Fabric softeners can be used in fabric cleaning compositions, compositions for addition to post-wash rinses of fabrics, or compositions for addition to hot air dryers with damp fabrics. may be contained in In both cases the conditioning process is carried out in an aqueous environment.

A number of textile conditioning compounds are known including soaps, green clays, quaternary ammonium salts and fatty amines.

All of these materials are used industrially, but they have various drawbacks. For example, quaternary amine salts are the most widely used, but are difficult to incorporate into liquid products except at relatively low concentrations, do not readily disperse in cold water, and, when used in excess, render treated fabrics water repellent. I end up making it.

The inventors have now discovered a class of textile conditioning agents that have particularly advantageous properties, and the present invention therefore provides that gI conditioning agents have the general formula (, I), where each R is Alkyl group having a carbon atom, R', R''
and R3 are each independently an alkyl group having 1 to 24 carbon atoms, or R3 is (CH2)OCH2CH(O
H) CHt) qcOo- group (q is 0 to 10), ^
is 31! due to one or more oxygen-containing groups! a truncated or substituted divalent hydrocarbon group; It is characterized by being an organic functional polyalkylsiloxane having a function that makes it electrically neutral.

To the knowledge of the inventors, UK Patent No. 1549180

For example, polysilicone compounds having hydrogen atoms in the side nails, ie compounds of the general formula (II), which can be prepared by the thorn method, can be used as starting materials; such materials are commercially available. The compound of general formula (1) is
Obtained by reaction with a suitable alkoxylated omega-unsaturated alcohol, a suitable allyl epoxy ether and an acid salt of a tertiary amine. Therefore, starting from a polysiloxane of the general formula (■) (wherein R is methyl, n=75 and m-!-p=7), an alkoxylated unsaturated alcohol of the formula % formula % is used as a starting material. , formula C112=C1

Compositions used in the methods of the invention can take a variety of forms. For example, in addition to textile conditioning agents, surfactants selected from anionic, nonionic and cationic surfactants, mixtures thereof or mixtures with other surfactants, water-soluble precipitates or gold ash ionic encapsulation builder substances. or detergent building materials such as ion exchange builder materials, bleaching agents such as peroxy bleach optionally with added bleach activators, alkaline materials such as sodium silicate, fillers such as sodium sulfate, and It can be a liquid or solid textile cleaning product that can contain other conventional ingredients of such compositions.

Further, the composition used in the present invention may be in the form of a rinse conditioning composition, for example, in addition to the textile conditioning agent, an electrolyte, an emulsifier, a viscosity modifier, a thickener, etc.
It may be in the form of a liquid rinse conditioning composition that may contain a youth colorant and other conventional ingredients of such compositions.

Additionally, the compositions used in the process of the invention may be in the form of products used in hot air rotary smoke dryers, such as powder form contained in a dispersion vehicle or sheet form coated or impregnated onto a visible substrate material. good.

Furthermore, the compositions used in the invention may be in a form suitable for direct addition to textiles, for example in the form of an aerosol spray containing at least a textile conditioning agent and a suitable propellant.

In addition to siloxane conditioning agents, all of the above products may contain other fabric conditioning agents such as other fabric softeners (especially water-insoluble cationic and nonionic softeners), antistatic agents (especially water-soluble cationic materials), fragrances, drape agents, anti-wrinkle agents and ironing aids.

Suitable water-insoluble cationic and nonionic softeners are described in European Patent Application No. 122141 (Unilever)
and European Patent Application No. 59502 (Procte
r and Gaml+Ies), and the disclosures of these documents are hereby incorporated by reference.

When the composition is in the form of a rinse conditioning composition, the total level of polyalkylsiloxane and nonionic fabric softener, if present, is 3 to 30% by weight of the composition. In use, such compositions are added to water to form a liquid and contacted with the fabric to be treated. -Finally, the total concentration of polyalkylsiloxane and nonionic fabric softener is about 20 ppm to 500 ppm.

After treatment, the test fabric was line-dried and rated against a standard of terry toweling fabric. Softness was determined. Each test fabric was given a softness rating.

The results obtained are shown below, assuming that the lower the softness index, the better the softness.

The results are shown below.

E1 Milk 1 Soil Re W Row 4 > 600 As is clear from the above results, the soft material of the present invention not only has a textile softening effect comparable to known soft materials, but also particularly compared to other silicone materials. It also has an improved rewetting effect.

In these examples, compositions containing nonionic fabric softeners and polysiloxanes were prepared according to the compositions shown below.6 The compositions were prepared by melting the active ingredients at 70°C. . The molten mixture thus formed was dispersed in hot water at 70°C and cooled to room temperature.

The treated polyester cotton fabrics were tested for softness and rewetability as described above. The results obtained are shown below.

The softness grade of the untreated fabric was i8.

The following freeze/thaw tests were conducted for Examples 11-14.

The test compositions were stored in screw-capped polyethylene suits at a temperature of about -10°C for 16 hours. The composition was then allowed to melt at ambient temperature for 8 hours.

Visually check the condition of each composition after one freeze/thaw cycle.
