Definitions

  • the invention is in the field of textile finishing and relates to new treatment agents which impart a sensory effect to fibers, yarns and the textiles made therefrom, a process for temporarily finishing these substances and the use of special mixtures of waxes, emulsifiers and crystallization regulators. catalysts for the production of such agents.
  • a sufficient amount of suitable substances namely typical oil components, are known from cosmetics which, through intelligent mixing, for example in the form of a so-called spreading cascade, also meet these requirements over a longer period of time.
  • suitable active ingredients in which the person skilled in the art can be guided by the experience from cosmetics, but in the permanent application of these compounds from the aqueous emulsion or dispersion, which is not easily achieved in this way.
  • the object of the present invention was therefore to provide new textile finishing agents, with the aid of which sensor-active substances, which are activated by the heat of the skin or by the supply of heat, for example when ironing or in the dryer, can be technically simple and durable on fibers , Yarns or the textile fabrics made from them.
  • the invention relates to aqueous textile finishing agents containing
  • the ternary mixtures according to the invention fulfill the task set out with great reliability.
  • the application can be carried out without problems from the aqueous phase, the melting point of the waxes acting as sensors being selected such that it is preferably just above the temperature on the skin surface. In this way, the sensory abilities of these active ingredients only develop immediately upon skin contact through the interaction of skin temperature and mechanical friction between the textile and skin.
  • the emulsifiers ensure that the waxes, which are insoluble in the aqueous phase, are sufficiently emulsified or dispersed so that a homogeneous preparation is obtained.
  • the decisive part of the invention is borne by the crystallization regulators, which have the task of ensuring that the wax crystals are not present during the preparation of the preparations, for example using the PIT process or simply by mixing the components above the melting point of the waxes and then cooling them get too big.
  • the present invention includes the knowledge that waxes with an average particle diameter of more than 6 ⁇ m can no longer be applied permanently to fibers, which means that the desired sensory effect is not experienced by the consumer.
  • lipophilic waxes are by nature not very critical. It is based on which sensory effects are to be brought about on the skin, for which the specialist can essentially fall back on the experience from cosmetics. It makes sense to use waxes that have a melting point just above the temperature on the surface of the skin, since this ensures that the sensory effect is triggered directly by skin contact. Waxes with a significantly lower melting point are more difficult to incorporate into the formulations and are susceptible to temperature influences during storage; those with significantly higher melting points are practically ineffective when in contact with the skin. An exception would be preparations in which the sensory effect (eg the well-known "easy ironing") is triggered in another way, for example when ironing.
