Abstract:
A process for producing a fragrance-emitting fiber comprising the sequential steps of:(a) providing polymer matrix particles having releasably entrapped therein at least one aroma-imparting component which optionally has efficacious antimicrobial properties in a concentration of from about 1% up to about 45% by weight of the polymer particles and optionally (i) one or more antimicrobial substances and/or (ii) at least one compatible coloring material or color-forming material which is useful for ascertainment of the exhaustion or substantial reduction of fragrance; (b) optionally admixing the matrix particles with a compatible polymer whereby a matrix polymer mixture is formed; and (c) forming the polymer particles or the matrix polymer mixture into one or more continuous fragrance-imparting component-emitting fibers of from about 3 denier up to about 60 denier.
