Abstract
A method of treating textile which is yarn or fabric containing spandex fibres, comprising contracting the textile with a perfume so that the perfume is deposited on the fabric. The perfume contains a mixture of fragrance materials which preferentially deposit on the spandex fibres. The yarn of fabric may be made up into garments.
Claims11
A spandex fiber having fragrance materials deposited on the spandex fiber from a solution wherein the fragrance materials are selected from:
- Category A) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1050, and
- Category B) esters ethers, nitrites, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar station phase) of at least 1300.
A textile which comprises spandex and other fibers and which has fragrance materials preferentially deposited on the spandex fibers from a solution wherein the fragrance materials are selected from:
- Category A) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1050, and
- Category B) esters ethers, nitrites, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar station phase) of at least 1300.
A textile which is yarn or textile goods that have never been worn as garments and that contain spandex, comprising contacting the textile with a solution containing a perfume composition which is a mixture of fragrance materials, so that fragrance materials are deposited on the textile, wherein the perfume composition contains at least 50%, by weight of the perfume composition, of fragrance materials selected from
- Category A) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1050, and
- Category B) esters, ethers, nitriles, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1300.
A method of treating textile which is yarn or textile goods that have never been worn as garments and that contain spandex, comprising contacting the textile with a solution containing a perfume composition which is a mixture of fragrance materials, so that fragrance materials are deposited on the textile, wherein the perfume composition contains at least 50%, by weight of the perfume composition, of fragrance materials selected from
- Category A) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1050, and
- Category B) esters, ethers, nitrites, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1300.
A method of treating a spandex fiber comprising contacting the fiber with a solution containing a perfume composition which is a mixture of fragrance materials, so that fragrance materials are deposited on the spandex fiber, wherein the perfume composition contains at least 50%, by weight of the perfume composition, of fragrance materials selected from
- Category A) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1050, and
- Category B) esters, ethers, nitriles, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log10P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar stationary phase) of at least 1300.
