  • Patent number: 5232769
    Abstract: This invention relates to a microcapsule having a particle diameter of 2.about.300 .mu.m and comprising a substance acting to improve physiological conditions of human skin, for example, substances exhibiting such effects as skin whitening, aging preventive, humidity preservable, itch suppressive, pain-killing, or antiphlogistic ones, and/or aromatic agents contained within the filmy coating of synthetic high molecular substance. The microcapsule is not broken when making, processing, or laundering the textile structure, but is gradually broken when the textile structure is put on the human body, used for another purpose, or subjected to intentional application of friction or pressure thereto, and sustainedly releases acting substances contained therein.

  • Patent number: 4917920
    Abstract: A fragrant fibrous structure, such as fabrics, apparels or the like, provided with microcapsules encapsulating a perfume and a resinous binder, preferably a silicone resin, in a weight ratio of 2/1 to 1/5, an add-on amount in the aggregate of said microcapsules and resinous binder being 0.3.about.7.0% based on the weight of the portion to which said microcapsules and resinous binder are adhered, of the fibrous structure. The process for preparing the above fibrous structures comprises applying a treating liquid comprising microcapsules composed of an external wall of a formaldehyde based resin enclosing a perfume and a resinous binder, preferably a low temperature reactive organopolysiloxane prepolymer emulsion, preferably together with a pressure absorbing agent, to at least a part of a fibrous structure and then drying the fibrous structure at a temperature of less than 150.degree. C. to fix said microcapsules on fiber surfaces of the fibrous structure.
