Means for making textiles

The invention relates to novel fabric softeners and a process for simultaneous washing and softening iron textiles using these softeners »

The treatment of textiles with agents such as brighteners, softeners, antistatic agents, germicides and Such is today a well-developed and economically important branch of industry »In many In some cases, the textile material is turned into clothing and other textiles for use before processing factory fitted »some of the so in the Finishes brought in to textiles are retained for a certain period of time; however, others will be in a relatively short time and generally after or during the first wash or during the following Washes removed from the textile material »textile fibers such as wool and cotton and also synthetic fibers such as nylon, dacron polyester

In addition, as I said, much of the equipment brought in from the factory is not permanent on the

Tissues fixed accordingly go initially at one beneficial properties present in certain fabrics with the first wash or the following Washes lost. Many fabrics or items of clothing therefore require renewed treatment by the Consumers, if their utility value and their advantageous properties are to be retained «.

The use of various chemicals and, in particular, cationic quaternary ammonium compounds as fabric softeners is known to those skilled in the art. It is also known to add such substances because of their softening effect during washing and especially in the rinse cycle of a washing process. which are predominantly cationic in nature, are not compatible with the most important enside type used for household laundry, since this is of an anionic nature and in particular of the alkali alkylbenzenesulfonate type with a higher alkyl group Alkyl-phenyl-SCK-M, where "alkyl ^{11 is} the alkyl radical of a fatty acid and M is hydrogen or a

Alkalication is «, these compounds represent a known class of anionic surfactants, under which fall for example sodium dodecylbenzenesulfonate, potassium dodecylbenzenesulfonate, sodium tridecylbenzenesulfonate and sodium hexadecylbenzenesulfonate o Other surfactants of this type are the alkali salts of the higher alkyl sulfonic acids and the alkali dialkyl sulfosuccinates, e.g., sodium dioctyl sulfosuccinate and Sodium dihexyl sulfoeucclnate, sodium sulfoethyl phthalate, fc sodium oleyl p-anisidine sulfonate, sodium octylphenoxyethoxyethyl sulfonate, etc., the alkali alkyl sulfates, e.g. Sodium lauryl sulfate, and the olefin sulfonates, e.g. Sodium tetradecene sulfonate.

Among the alkylbenzenesulfonic acids mentioned and their salts, the compounds most frequently used in commercial detergents include the biodegradable products, which are characterized by a linear alkyl substituent with 10 to 22 and preferably 12 to 15 carbon atoms. It goes without saying that the chain length is generally an average chain length, since in the manufacture of these products ivr. general equilibrium means with common chain links Ter d (it has been Ee ί & Ί .-. however ΗΊεγ,. flow ■ · ::% practical

pure olefins and alkylating agents used in other processes auoh alkylated Benzolaulfonate can be obtained, the alkyl part essentially, doho to at least 99 # _{t has} the same chain length, for example consists of a chain with 12 or 13 or 14 or 15 carbon atoms further characterized by the position of the benzene ring in the straight alkyl chain, where all positional isomers (ie from ot to CJ) are suitable and are used.

When you have a cationic compound like the one above mentioned cationic quaternary ammonium compounds as plasticizers in conjunction with one of the above If the anion-active surfactants described are used, there is absolutely no softening effect on textiles As a result of the incompatibility, surfactant is also removed from the washing liquor, so that additional surfactant has to be added to achieve the desired washing effect. Because of these difficulties, it is necessary to use the previously available to give cationic softener in the absence of anionic surfactant to the textiles, so that one these cationic softeners are usually not put in the wash cycle but in the rinse cycle of a washing process.

Auflerdem it is known that fabrics washed yellowing tendency when wurden- treated with tetionischen agents This V & rgilbea of textiles which have been treated with cationic materials, it is 1) by highly colored impurities or by-products in various commercial cationic Auerüstungemitteln or 2) the presence of larger amounts of iron in the finish, which leads to the formation of typical sisen stains, or 3) caused by the presence of alkali when ironing or mangling textiles treated with cationic compounds

The present invention is therefore the task based on a means for whitening textiles to propose which of the above disadvantages does not have doho especially with those in detergents usual anion-active Tenslden is compatible, so in the household laundry in the wash liquor can be given, and does not lead to yellowing of the textiles treated with it.

This task is according to the invention on the one hand by dissolved an agent for softening textiles, which is an amine oxide of the general formula

where R ^ is a higher alkyl group with at least 18 and preferably 18 to 22 carbon atoms and B ₂ and R, independently of one another, represent lower, optionally substituted alkyl groups with 1 to 4 carbon atoms, and an alkali metal group of a lower alkyl substituted benzene, toluene or contains xylenesulfonic acid. According to a special embodiment, this agent can also contain an alkali metal alkyl methyl naphthalene sulfonate.

On the other hand, the invention has a method of washing and softening fabrics at the same time on the subject to which an agent of the type described above is added to the washing liquor "

Suitable for the fabric softeners of the invention Amine oxides are for example
