ISO/TC 38/SC 2/WG 4 - Appearance retention

This document specifies a method for evaluating the appearance of textile fabrics after induced wrinkling. This document is applicable to all kinds of textile fabrics. NOTE A digital description of the ISO wrinkle replicas is given in Annex A.

This document specifies three procedures (diagonal marking, inverted-T marking and mock-garment marking) to measure the spirality or torque of woven and knitted fabrics after domestic laundering. The results obtained from different procedures will not always be comparable. This document is not intended to measure the spirality of fabrics as manufactured, but rather the spirality after laundering. NOTE Some fabric constructions, such as denim, can have spirality intentionally introduced during manufacturing. Fabrics made on circular knitting machines can have inherent nonverticality of wale alignment.

This document specifies a method of test for evaluating the appearance of apparel and other textile end products after one or several domestic washing and drying treatments. The appearance evaluated includes colour change, pilling, fuzzing, matting appearance of fabrics, smoothness appearance of flat fabric and seams, and the retention of pressed-in creases in garments and other textile products, damage of components ? buttons, press fasteners, slide fasteners, etc. This document is applicable to any washable textile end product of any fabric construction. Techniques for seaming and creasing are not included since the purpose is to evaluate textile end products as they are supplied from the manufacturer or as ready-to-use. Techniques for seaming and creasing are controlled by fabric properties. This method has been developed primarily for use with domestic washing machines of Type B as defined in ISO 6330, but it can be used with any type of machine defined in ISO 6330. It is recognized that prints and patterns can mask the wrinkled appearance present in textile end products. The rating process is, however, based on the visual appearance of specimens including such effects.

ISO 16847:2016 specifies a method for assessing the matting appearance of the napped fabrics (fleece fabrics) tested, after one or several cleansing treatments. This method has been developed for use primarily with Type B domestic washing machines, as defined in ISO 6330, in the cleansing process. However, it is possible to use it with Type A machines, as defined in ISO 6330. This test method can be used for judging matting appearance after other cleansing processes.

ISO 7769:2009 specifies a test method for evaluating the retention of pressed-in creases in fabrics after one or several cleansing treatments. A technique for inserting creases is not included as this is controlled by fabric properties. This method has been developed for use primarily with type B domestic washing machines, as defined in ISO 6330, in the cleansing process. However, it may be possible to use it with type A machines, as defined in the same International Standard.

ISO 7770:2009 specifies a test method for evaluating the smoothness appearance of seams in fabrics, after one or several cleansing treatments. A seaming technique is not included, since the purpose is to evaluate existing seams. This method has been developed for use primarily with type B domestic washing machines, as defined in ISO 6330, in the cleansing process. However, it may be possible to use it with type A machines, as defined in the same International Standard.

ISO 7768:2009 specifies a method for assessing the retention of the original smooth appearance, after one or several cleansing treatments, of the fabrics tested. This method has been developed for use primarily with Type B domestic washing machines, as defined in ISO 6330, in the cleansing process. However, it may be possible to use it with Type A machines, as defined in the same International Standard. This test method could be used for judging smoothness appearance after other cleansing processes.

ISO 16322-1:2005 specifies a method of measuring the percentage of wale spirality change in weft-knitted jersey garments produced on knitting machines, following laundering. The results obtained from different procedures may not be comparable. The change in spirality is calculated from measurements on knitted garments before and after laundering.

ISO/TR 16323:2003 specifies a test method for the objective evaluation of fabric appearance with a three-dimensional measuring apparatus.

ISO 9867:2009 describes a method for evaluating the appearance of textile fabrics after induced wrinkling. It is applicable to fabrics made from any fibre or combination of fibres.

ISO 15487:2009 specifies a method of test for evaluating the smoothness appearance of flat fabric and seams, and the retention of pressed-in creases in garments and other textile products after one or several domestic washing and drying treatments. It is applicable to any washable textile end product of any fabric construction. Techniques for seaming and creasing are not included since the purpose is to evaluate textile end products as they are supplied from the manufacturer or as ready-to-use. Techniques for seaming and creasing are controlled by fabric properties.

ISO 16322-3:2005 specifies procedures to measure the spirality or torque of woven and knitted garments after laundering. The results obtained from different procedures may not be comparable. ISO 16322-3:2005 is not intended to measure the spirality of garments as manufactured, but rather the spirality after laundering. Note that some fabric constructions, such as denim, may have spirality intentionally introduced during manufacturing. Garments made of fabrics from circular knitting machines may have inherent nonverticality of wale alignment.
