• a water-soluble ammonium salt containing at least one fatty acid residue, at least one further quaternary compound with a long-chain alkyl residue and polyethylene wax dispersed in a known manner.
• the use of these softening agents is claimed.
• polyethylene dispersions are well suited for improving the grip, in particular also for improving the sewability, of textile materials.
• fatty acid alkanolamides were used to achieve a soft, smooth surface.
• quaternary ammonium compounds are also suitable as handle components for fibrous materials, in particular textiles.
• DE-A 2 833 172 discloses water-soluble, quaternary ammonium salts having at least one fatty acid residue as softening agents and their use for the antistatic and finishing of organic fiber materials. This known equipment provides good hydrophilicity, but the handle is unsatisfactory and, above all, yellowing of the finished material can be observed to a considerable extent.
• hydrophilic softening agents all of which are aimed for Combine properties and can also be produced inexpensively if they have the composition described in more detail in claim 1.
• the essential components of the hydrophilic softening agents according to the invention are components (1). These compounds are largely known from DE-A 2 833 172. The production of the same is fundamentally known from this literature reference and can be carried out in the manner described there. Thus, only the compounds quaternized with a di-Cl to 2-alkyl ester of a Cl to 2-alkylphosphonic acid are used as components (1), with the alkyl radical having 9 to 24 C atoms of component (1) to a lesser extent (too less than 50%) can also be unsaturated.
• Components (1) are present in the softening agents in amounts of 2 to 10, in particular 2 to 6,% by weight.
• At least one other quaternary ammonium compound with at least one long-chain, saturated and / or unsaturated alkyl radical which is different from the components (1) is used as components (2).

• the emulsifiable polyethylene is one with functional groups, in particular COOH groups, which can be partially esterified. These functional groups are introduced by oxidation of the polyethylene. However, it is also possible to obtain the functionality by copolymerizing ethylene with, for example, acrylic acid.

• hydrophilic softening agents according to the invention can also contain emulsifiers and other known constituents.
• emulsifiers are indicated on a case-by-case basis when relatively small amounts of components (1) and especially (2) are used or when increased requirements for compatibility with other finishing agents, e.g. optical brighteners.
• the known nonionic and / or cationic emulsifiers different from (1) or (2) are used as emulsifiers.
• Organopolysiloxanes are to be mentioned as further known components.
• hydrophilizing agents in particular are used acting silicones into consideration. This addition makes the handle even softer, more pleasant and also has a favorable influence on the hydrophilicity.

• the textiles are treated in a known manner with liquors which contain 15 to 80 g / l, in particular 20 to 60 g / l, of the hydrophilic softening agents, based on a dispersion with a total solids content of about 20% by weight. which results in a coating of about 0.2 to 3% by weight of solid substance on the fiber material.
• the softening agents according to the invention can also advantageously be used by the pull-out process. In this method, approximately 1 to 6, in particular 2 to 4.5%, based on the weight of the goods (based on the soft handle dispersion) are used, depending on the required circulation.
