Beschreibung
Zusammenfassung:	A fragrant fibrous stucture, 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 SIMILAR 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 DEG C to fix said microcapsules on fiber surfaces of the fibrous structure.
