IntroductionPills are formed when fibres on a fabric surface “tease out” and become entangled during we
28、ar. Such surface deterioration is generally undesirable, but the degree of consumer tolerance for a given level of pilling will depend on the garment type and fabric end use.Generally, the level of pilling which develops is determined by the rates of the following parallel processes:a) fibre entangl
29、ement leading to pill formation;b) development of more surface fibre;c) fibre and pill wear-off.The rates of these processes depend on the fibre, yarn, and fabric properties. Examples of extreme situations are found in fabrics containing strong fibres versus fabric containing weak fibres. A conseque
30、nce of the strong fibre is a rate of pill formation that exceeds the rate of wear-off. This results in an increase of pilling with an increase of wear. With a weak fibre, the rate of pill formation competes with the rate of wear-off. This would result in a fluctuation of pilling with an increase of
31、wear. There are other constructions where surface fibre wear-off occurs before pill formation. Each of these examples demonstrates the complexity of evaluating the surface change on different types of fabric.The ideal laboratory test would accelerate the wear processes a), b), and c) by exactly the
32、same factor and would be universally applicable to all fibre, yarn, and fabric types. No such test has been developed. However, a test procedure has been established in which fabrics can be ranked in the same order of fuzzing and pilling propensity as is likely to occur in end use wear.Particular at
33、tention is drawn to Annex A which gives advice on the maintenance and checking of the apparatus and liners. It is recommended that Annex A be studied prior to carrying out the procedure.In Bibliography, some listed national standards have been taken into consideration as they refer to the use of the
34、 equipment, on which this part of ISO 12945 is based.DIN EN ISO 12945-3:2014-10 EN ISO 12945-3:2014 (E) 4 1 ScopeThis part of ISO 12945 describes a method for the determination of the resistance to pilling, fuzzing, and matting of textile fabrics using the random tumble pilling tester. This method i
35、s applicable to most of woven and knitted fabrics, including napped fabrics (fleeces, inlay fabrics).This method is not applicable to fabrics which cannot tumble freely.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensab

40、EN ISO 12945-3:2014 (E) 5 3.5mattingdisorientation of the raising fibres from a napped fabric, which produces a visible surface change4 PrincipleSpecimens are tumbled randomly, under defined conditions, in a lined cylindrical test chamber. Fuzzing, pilling, and matting are assessed visually after a
41、defined period of tumbling.NOTE Any special treatment of the laboratory sample, i.e. washing, cleaning could be as agreed upon between the interested parties and be described in the test report.5 Apparatus and auxiliary materials5.1 ApparatusThe apparatus shall include:5.1.1 Device, consisting of on
42、e or several cylindrical test chambers, horizontally positioned, with the inside dimensions of (152,4 1,0) mm in depth and (146 1) mm in diameter. In the centre of each chamber is a horizontal shaft with cross rods (impellers) which rotate at 1 200 rpm (see Figure 2). This device shall have a mean c
43、apable of sustaining a steady movement of the test specimens (thus, avoiding jamming during the test); this functionality can be set by either an air jet (which can blow onto the cylinder wall) or plastic blades (placed on the shaft, see Figure 2, which can move physically jammed test specimens from
44、 the cylinder wall).NOTE The use of either air jet device or plastic blades shall be reported.5.1.2 Lining material, polychloroprene liner. The polychloroprene liner shall conform to the following criteria as described in Table 1. Length and width of the polychloroprene liner shall be such that it f
45、its securely in the test chamber without gaps or bulging.Table 1 Criteria for polychloroprene linerCriteria Units Polychloroprene linerThickness mm 3,2 0,4Hardness IRHDa60 70aIRHD is an abbreviation for international rubber hardness degree and shall be checked according to ISO 48 (method N, i.e. nor
46、mal test).5.1.3 Viewing cabinet, illuminated by a white fluorescent tube or bulb (the colour temperature of the light source is not critical) to give uniform illumination over the surface of the specimen(s) and masked in such a way that the observer does not look directly into the light. The illumin
47、ant should be positioned at an angle between 5 and 15 to the plane of the specimen (see Figure 1). The distance between the eye and the specimen should be between 30 cm to 50 cm for normal corrected vision.DIN EN ISO 12945-3:2014-10 EN ISO 12945-3:2014 (E) 6 Key1 light source2 observer3 specimenFigure 1 Illumination of specimens5.2 Auxiliary materials5.2.1 Glue, a white water-based all-purpose glue, for sealing the edges of the specimens.NOTE Generally, thi
