摘要:
A process for producing an evenly-dyed fabric comprising both cotton fibres and man-made cellulose fibres, in which a fabric is manufactured from both said fibres and is dyed, is characterised by impregnating the man-made cellulose fibres, prior to manufacture of the fabric, with a water-soluble, flexible linear polymer and a cross-linking agent reactive with cellulose, and, at a stage of the process prior to dyeing of the fabric, effecting a cross-linking reaction between the man-made cellulose fibres and the cross-linking agent, thereby producing a reduction in the dye affinity of the man-made cellulose fibres to a level more proximate to the dye affinity of the cotton fibres.

The invention relates to a mixture, comprising (A) 10 to 90 wt. % of at least one C6 to C18 alkyl ester, or C5 to C8 cycloalkyl ester of 2-cyano-3,3-diphenylacrylic acid and (B) 90 to 10 wt. % of at least one further compound, with at least one UV absorption maximum in the range 280 to 450 nm and structurally different from compound (A). Said mixture is suitable for the protection of human skin from damaging UV radiation and for the protection of coloured textile materials from colour fading.

摘要:
The present invention relates to a process for inhibiting (quenching) the effect of fluorescent whitening agents on cellulosic textile fibre materials treated, being treated or to be treated with fluorescent whitening agents, by the application of certain triazine-based ultra-violet absorption agent (UVAs), preferably those of formula (10) in which M, n1, n2, R9 and R10 are as defined in claim 2 and to the material so treated and also to processes for decontaminating detergent manufacturing apparatus and recycled industrial laundry water containing residual fluorescent whitening agent (FWAs).
摘要:
This invention relates to complexes of ultraviolet absorbers with quaternary ammonium compounds which are substantially free from unwanted salts. Such complexes are formed through ionic bonds formed between the two compounds. The inventive complexes are then removed of substantially all excess inorganic salt so as to obtain a UV absorber compound which exhibits improved light- and washfastness properties, which easily coats subject surfaces, which provides excellent non-fogging and non-cracking characteristics, and which also possesses anti-static, anti-microbial, and anti-abrasion properties. This invention also concerns methods of making and utilizing such inventive ultraviolet absorbing complexes.
