Definitions
- the present invention is directed to a method of use for the treatment of textile materials to improve the antifungal and/or antidustmite properties by applying to the textile materials a special selected antifungual or antidustmite agent by special application processes.
- Textile products that exhibit antifungal properties are highly desirable by the consumers. A few segments are of particular importance for such properties. For example, various studies have found that human feet are often infected with fungi resulting in various diseases such as Athlete's foot. Textile materials that exhibit antifungual properties and when incorporated as components for making shoes, could therefore be benefitial to consumers. In home textile segment, dustmites present in matrices, pillow cases have been linked to the increasing occurrence of allergy and asthma.
- the present invention is focused on the use of a special agent in textile products to provide the desirable antifungal and antidustmite efficacy.
- a selected antifungal substance can be incorporated onto various substrates made of man made as well as natural fibres to provide long lasting antifungal activities and antindustmite properties that are durable against repeated laundering, dry cleaning, weathering and/or other ageing processes.
- the treatment of such textile products with a selected agent and/or formulations that contain such an agent could be carried out in various processes such as padding, spraying and foam application processes as well as processes wherein polyacrylonitrile fibres are treated with the agent in the gel state.
- the present invention therefore, relates to a method of use for the treatment of textile material to improve the antifungal and/or antidustmite properties, comprising applying to the textile material a compound of formula
- the compound of formula (1) may be applied as aqueous formulation in diluted, solubilised, emulsified or, preferably, in dispersed form.
- Such aqueous formulations therefore can additionally comprise a small amount of an organic solvent, a surfactant, a dispersant, and/or an emulsifier. These components are useful for solubilisation and stabilisation of the compound of formula (1) in the aqueous formulation.
- the compound of formula (1) is applied in dispersed form it is preferably milled with an appropriate dispersant, conveniently using quartz balls and an impeller, for example to a particle size of 0.1 to 4 ⁇ m, especially 0.3 to 3 ⁇ m.
- Suitable dispersants for the compound of formula (1) are:
- - acid esters or their salts of alkylene oxide adducts typically acid esters or their salts of a polyadduct of 4 to 40mol of ethylene oxide with 1mol of a phenol, or phosphated polyadducts of 6 to 30mol of ethylene oxide with 1 mol of 4-nonylphenol, 1 mol of dinonylphenol or, preferably, with 1 mol of compounds which are prepared by addition of 1 to 3mol of unsubstituted or substituted styrenes to 1mol of phenol,
- polyadducts of 1 to 60 mol of ethylene oxide and/or propylene oxide with fatty amines, fatty acids or fatty alcohols, each containing 8 to 22 carbon atoms in the alkyl chain, with alkylphenols containing 4 to 16 carbon atoms in the alkyl chain, or with trihydric to hexahydric alkanols containing 3 to 6 carbon atoms, which polyadducts are converted into an acid ester with an organic dicarboxylic acid or with an inorganic polybasic acid,
- formaldehyde condensates such as condensates of ligninsulfonates and/or phenol and formaldehyde, condensates of formaldehyde with aromatic sulfonic acids, typically condensates of ditolyl ether sulfonates and formaldehyde, condensates of naphthalenesulfonic acid and/or naphthol- or naphthylaminesulfonic acids with formaldehyde, condensates of phenolsulfonic acids and/or sulfonated dihydroxydiphenylsulfone and phenols or cresols with formaldehyde and/or urea, as well as condensates of diphenyl oxide-disulfonic acid derivatives with formaldehyde.
- the compound of formula (1) is dispersed with at least one dispersant selected from the group consisting of condensates of ligninsulfonates and/or phenol and formaldehyde; condensates of formaldehyde with aromatic sulfonic acids; condensates of naphthalenesulfonic acid and/or naphthol- or naphthylaminesulfonic acids with formaldehyde; condensates of phenolsulfonic acids and/or sulfonated dihydroxydiphenylsulfone and phenols or cresols with formaldehyde and/or urea; and condensates of diphenyl oxide-disulfonic acid derivatives with formaldehyde.
- condensates of naphthalenesulfonic acid and/or naphthol- or naphthylaminesulfonic acids with formaldehyde are particularly preferred.
- Suitable solubilising agents are anionic, nonionic or zwitterionic and amphoteric synthetic, surface-active substances.
- Suitable anionic surface-active substances are:
- - sulfates typically fatty alcohol sulfates, which contain 8 to 18 carbon atoms in the alkyl chain, e.g. sulfated lauryl alcohol;
- - fatty alcohol ether sulfates typically the acid esters or the salts thereof of a polyadduct of 2 to 30 mol of ethylene oxide with 1 mol of a C -C ⁇ fatty alcohol;
