9、ization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to

10、be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used

11、to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of

12、the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

This change in appearance, known as matting, is more or

16、less severe and is related to the fibre, fabric or finishing characteristics.Based on the structure of other ISO standards dealing with the change in appearance after cleansing, this document has been elaborated to solve this situation.

17、6Textiles Test method for assessing the matting appearance of napped fabrics after cleansing1 ScopeThis document 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 pri

18、marily 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.2 Normative referencesThe follow

One of the domestic washing and drying procedures specified in ISO 6330,

24、one of the professional procedures specified in the series of ISO 3175 or one of the industrial procedures as specified in ISO 15797 is used, as agreed between the interested parties. If the interested parties decide that other cleansing processes are to be used, this fact shall be reported.5 Appara

25、tus5.1 Washing and drying apparatus, as specified in ISO 6330, professional care apparatus, as specified in ISO 3175 or industrial laundering apparatus as specified in ISO 15797.5.2 Lighting.The evaluation area shall be a darkened room, using the overhead lighting arrangement shown in Figure 2 and c

26、omprising the following items. Lamp dimensions should be chosen to extend beyond the overall surface of a test specimen and replicas, when used for the assessment.5.2.1 Two CW (cool white) fluorescent lamps, placed side by side, without baffle or glass, a minimum of 2 m in length each.5.2.2 One whit

29、ength direction.If the matting appearance shall be assessed on both faces, mark the front face.7 Procedure7.1 Treat each specimen according to one of the cleansing procedures specified in ISO 6330, ISO 3175 or ISO 15797, as agreed between the interested parties.7.2 If required, repeat the selected t

30、reatment four times, to give a total of five cycles (one cycle consists of one washing and one drying).7.3 Condition the test specimens in the standard atmosphere according to ISO 139 for a minimum of 4 h by hanging each specimen unfolded with the length direction vertical to avoid distortion.7.4 Fo

31、r the evaluation, carry out steps 7.5 to 7.11.7.5 Three observers shall rate each treated test specimen independently. ISO 2016 All rights reserved 3BS ISO 16847:2016ISO 16847:2016(E)7.6 Mount the test specimen on the viewing board (5.2.4) as illustrated in Figure 2, with the length direction vertic

32、al. If the matting appearance shall be assessed on both faces, proceed to 7.6 to 7.11 with the marked front faces, and then repeat 7.6 to 7.11 with the other faces.7.7 The overhead fluorescent light (5.2.1) shall be the only light source for the viewing board, and all other lights in the room shall

33、be turned off. It has been the experience of many observers that the light reflected from the side walls near the viewing board can interfere with the rating results. It is recommended that the side walls be painted black or that blackout curtains be mounted on either side of the viewing board to el

34、iminate the reflective interference.7.8 The observer shall stand directly in front of the specimen, 1,2 m away from the board. It has been found that normal variations in the height of the observer above and below the arbitrary 1,5 m eye level have no significant effect on the rating given.7.9 Assig

35、n the number of the grade which most nearly matches the appearance of the test specimen, or assign ratings midway between those whole-number standards which have no half-number standards separating them if the appearance of the specimens warrants it (see Table 1).7.10 A 5 rating represents the best

36、retention of original appearance, while a 1 rating represents the poorest retention of original appearance.7.11 Similarly, the observer shall independently rate each of the other two test specimens. The other two observers shall proceed in the same manner, assigning ratings independently.Table 1 Mat
