  • Patent number: 7700502
    Abstract: A textile finished with a biocidally active component is provided. The textile is characterized in that the biocidally active component is contained in the textile and comprises 2-n-octyl-4-isothiazolin-3-one and also, optionally, one or more other biocides and the biocidally active component is enclosed in microparticles composed of an aminoplast resin. The enclosure of the biocidally active component in the microparticles causes the biocidally active component to stay on the textile during the drying and curing involved in the finishing process. In addition, in practical use, the biocidally active component is only released slowly and is not washed off by exposure of the textile to rain or water. This stops a large part of the biocidally active component escaping during the finishing of the textile or being washed off the tenting, awnings, filters, tarpaulins, shower curtains and the like after just a few (rain) showers.
