Estimating the term…
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.
A fragrant fibrous structure which has microcapsules encapsulating a perfume adhered thereto by a resinous binder, the weight ratio of said microcapsules to said resinous binder being between 2:1 and 1:5, and the sum of the amounts of said microcapsules and resinous binder being between 0.3 and 7.0%, based on the weight of the portion of the fibrous structure to which said microcapsules and resinous binder are adhered.
A fragrant fibrous structure comprising fibers having s fineness of 0.7 denier or less/filament, which retains microcapsules encapsulating a perfume in interstices of the fibrous structure.
