Abstract: A new process for enhancing the hydrophilicity of the surface of a polyolefin or polyolefin copolymer article is characterized in that the surface is treated with an enzyme selected from oxidoreductases, especially of the cytochrome P450 family or enzymes classified as EC 1.13 or EC 1.14. The process is especially useful for the treatment of polypropylene films, fibres, or fabrics, inter alia for use in sanitary articles, threads, yarns, fabrics, textiles, garments, technical or household articles, printed or dyed cover films or packaging films.

Abstract: Polyolefin fiber fabrics can be endowed with oil-repellent properties by treating them first in a plasma atmosphere to raise their surface tension, then with a polyorganosiloxane containing polyoxyalkylene groups and finally with a polyacrylate or polyurethane containing perfluoroalkyl radicals. The fabrics thus obtained are useful for medical as well as other applications.

Abstract: Compositions according to the invention comprise water, a polyurethane or poly(meth)acrylate having perfluoroalkyl groups and a special siloxane. The treatment of fiber materials, in particular of nonwovens made of polypropylene, leads to articles which have oil-, water- and alcohol-repellency properties and can be used in the medical sector.

Abstract: Compositions comprising acrylato-functional polysiloxanes can be prepared by reacting dihydroxypolyorganosiloxanes with a mixture of two different acrylato-functional silanes. The compositions can be used for treating sheetlike textiles, particularly for curtain coating.

Abstract: Polyorganosiloxanes containing urea groups can be obtained in the form of aqueous dispersions by firstly dissolving them in an organic solvent, then dispersing this solution with water with co-use of auxiliaries, subjecting the mixture to homogenization and then at least partially removing the organic solvent. The aqueous dispersions prepared in this way are suitable as additive for detergents, fabric softeners, haircare compositions, shampoos and for textile finishing.

Abstract: Textile fabrics comprising not less than 70% by weight of cellulose are treated with solutions of one or more silicon compounds in liquid ammonia. Cellulose molecules are crosslinked by the treatment, producing good wrinkle resistance and good water retention capacity.

Abstract: Gaseous or volatile substances which are either themselves odor-active or components of odor-active mixtures of substances are applied to fabrics. The amount of these substances adsorbed by the textiles is then determined. It is then determined what amount of these substances is desorbed again by the textiles upon storage. Comparison of the results which are obtained on textiles which had been finished beforehand with textile auxiliaries with the results of non-finished textiles enables statements to be made regarding odor-inhibiting properties of textile auxiliaries.
