A perfuming agent including a compound represented by Formula (I):

##STR00001## where R.sup.1 is a tert-butyl group, and R.sup.2 is an ethyl group. A fragrance composition, including a compound represented by Formula (II), and a compound represented by Formula (I):

##STR00002##

where R.sup.1 and R.sup.3 are each independently an alkyl group having 1 or more and 5 or less of carbon atoms, and R.sup.2 and R.sup.4 are each independently a hydrogen atom or an alkyl group having 1 or more and 4 or less of carbon atoms.

Disclosed is a high-strength polyacrylate textile material and the production method for the said material, which includes the process of eliminating the stress in the raw material (polyacrylonitrile-based textile material) before the crosslinking, hydrolysis, acid and salt processes without allowing the material to physically shrink, so that the amount of shrinkage in crosslinking, hydrolysis, acid and salt processes decreases spontaneously.
