ISO/TC 38/WG 23 - Biological properties of textiles

This document specifies a test method for the determination of reduction activity of textile products against specific proteins which shows antigen-antibody reaction. This document only specifies the reduction activity against those proteins on the surface of textile products. It does not specify a testing method to evaluate the allergenic reaction against human beings. Specific proteins which show antigen-antibody reaction are proteins derived from pollen, mite and other sources. Other specific proteins can be used after appropriate validation described in this document. Enzyme-linked immunosorbent assay is used to quantify the amount of those proteins in this document. This document is applicable to textile products include woven, knitted and nonwoven fabrics, fibres, yarns, braids, etc.

This document specifies quantitative test methods to determine the antibacterial activity of all antibacterial textile products including nonwovens. This document is applicable to all textile products, including cloth, wadding, thread and material for clothing, bedclothes, home furnishings and miscellaneous goods, regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting). This document covers three inoculation methods for the determination of antibacterial activity: a) absorption method (an evaluation method in which the test bacterial suspension is inoculated directly onto specimens); b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto specimens); c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto specimens). NOTE Based on the intended application and on the environment in which the textile product is to be used, and also on the surface properties of the textile properties, the user can select the most suitable inoculation method. This document also specifies the colony plate count method and the adenosine triphosphate (ATP) luminescence method for measuring the enumeration of bacteria.

This document specifies testing methods for the determination of the antiviral activity of the textile products against specified viruses. Due to the individual sensitivities, the results of one test virus cannot be transposed to other viruses. The textile products include woven and knitted fabrics, fibres, yarns, braids, etc.

ISO 17299-4:2014 specifies a deodorant testing method using analytical instruments after using condensation sampling methods for all textile products. This method is applicable to gaseous odour chemicals, such as indole, methyl mercaptan, hydrogen sulfide, isovaleric acid, and nonenal.

ISO 13629-2:2014 specifies a test method for quantitative determination of antifungal activity by plate count method. ISO 13629-2:2014 is applicable to various kinds of textile products such as fibres, yarns, fabrics, clothing, bedclothes, home furnishings, and other miscellaneous goods.

ISO 17299-5:2014 specifies a deodorant test method using an odour analyser equipped with multiple metal-oxide semiconductor sensors against composite odours. The artificial composite odours used in ISO 17299-5:2014 are a quasi sweat odour, a quasi body odour (nonenal mixture odour) and a quasi excrement odour. ISO 17299-5:2014 applies to all kinds of textile products, such as woven fabrics, knits, threads, yarns, fibres, braids, cords, etc.

ISO 17299-2:2014 specifies a deodorant testing method using a detector tube for all textile products. This method is applicable to the odour component chemicals of ammonia, acetic acid, methyl mercaptan, and hydrogen sulfide.

ISO 17299-1:2014 specifies the general principle of the deodorant textile products and deodorant testing methods for textile products, such as woven fabric, knit, nonwoven, fibres and yarns, braiding products, tapes and slings.

ISO 17299-3:2014 specifies a gas chromatography test method for the deodorant testing of all textile products. This method applies to the odour component chemicals, such as indole, isovaleric acid, nonenal, and acetic acid with added sodium chloride (NaCl). Two preparation methods are described.

ISO 13629-1:2012 specifies a test method for the quantitative determination of the antifungal activity by measuring the intensity of luminescence produced by an enzymatic reaction [adenosine triphosphate (ATP) method]. ISO 13629-1:2012 is applicable to various kinds of textile products, such as fibres, yarns, fabrics, clothing, bedclothes, home furnishings and other miscellaneous goods.

ISO 18184:2014 specifies testing methods for the determination of the antiviral activity of the textile products. The textile products include woven and knitted fabrics, fibres, yarns, braids, etc.

ISO 20743:2013 specifies quantitative test methods to determine the antibacterial activity of all antibacterial textile products including nonwovens. ISO 20743:2013 is applicable to all textile products, including cloth, wadding, thread and material for clothing, bedclothes, home furnishings and miscellaneous goods, regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting). Based on the intended application and on the environment in which the textile product is to be used and also on the surface properties of the textile properties, the user can select the most suitable of the following three inoculation methods on determination of antibacterial activity: a) absorption method (an evaluation method in which the test bacterial suspension is inoculated directly onto specimens); b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto specimens); c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto specimens). The colony plate count method and the ATP (ATP = Adenosine Tri-phosphate) luminescence method are also specified for measuring the enumeration of bacteria.

ISO 20743:2007 specifies quantitative test methods to determine the antibacterial activity of antibacterial finished textile products including nonwovens. ISO 20743:2007 is applicable to all textile products, including cloth, wadding, thread and material for clothing, home furnishings and miscellaneous goods regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting). Based on the intended application and on the environment in which the textile product is to be used, the user can select the most suitable of the following three methods on determination of antibacterial activity: a) absorption method (an evaluation method in which test bacterial suspension is inoculated directly onto samples); b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto samples); c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto samples). The colony plate count method and the ATP (Adenosine Tri-phosphate) luminescence method are also specified for measuring the enumeration of bacteria.
