Definitions

• the present invention relates to a process for improving the sensory properties of textiles and to the use of certain aqueous agents for this purpose.
• the sensory properties of textiles resulting from conventional washing and cleaning operations are an important criterion for the consumer to judge.
• This is not only about the softness, but there are also other criteria demanded by consumers.
• This includes the smoothness, the fact that residues remain on the fiber, the grip, the elasticity of the material, its flexibility but also, for example, the noise that occurs when crumpling or folding the laundry.
• a particular issue is the moisture absorption of the fabric, as e.g. When sweating large amounts of water are released, which, in order to convey a pleasant feel of the textiles, must be quickly dissipated.
• the present invention is therefore based on the problem of providing a method which significantly enhances the sensory properties of fabrics after washing can improve. It has now been found that certain aqueous formulated agents are suitable to fulfill this task.
• the aqueous agents described above are applied to textiles.
• Suitable methods here can be, in particular, the spraying of the aqueous compositions with suitable technical aids.
• it is quite possible to apply the aqueous agents differently to the textiles for example in the sense of a laundry after-treatment, possibly at elevated temperature, by bringing the items of laundry into contact with the aqueous agents for a suitable period of time in the context of the present technical teaching.
• This can also be achieved, for example, by using a correspondingly equipped so-called "dryer sheet", which is preferably brought into contact with the laundry to be treated in the tumble dryer, and its active ingredients are thus transferred to the textile.
• the finishing of the textiles is preferably temporary, and thus distinguishable from the permeant equipment used in textile manufacture.
• the agents described are applied to the textiles in the form of encapsulated active ingredients during or after the wash cycle.
• a preferred embodiment provides that the aqueous agents are applied to the items of laundry or textiles by spray application in the sense of the present technical teaching.
