26、ervedBS EN ISO 12945-3:2014ISO 12945-3:2014(E)IntroductionPills are formed when fibres on a fabric surface “tease out” and become entangled during wear. Such surface deterioration is generally undesirable, but the degree of consumer tolerance for a given level of pilling will depend on the garment t

27、ype and fabric end use.Generally, the level of pilling which develops is determined by the rates of the following parallel processes:a) fibre entanglement 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,

28、 and fabric properties. Examples of extreme situations are found in fabrics containing strong fibres versus fabric containing weak fibres. A consequence 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.

29、 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 wear. There are other constructions where surface fibre wear-off occurs before pill formation. Each of these examples demonstrates the complexity of ev

30、aluating the surface change on different types of fabric.The ideal laboratory test would accelerate the wear processes a), b), and c) by exactly the 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 be

31、en 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 attention 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 p

32、rior to carrying out the procedure.In Bibliography, some listed national standards have been taken into consideration as they refer to the use of the equipment, on which this part of ISO 12945 is based.

33、 of the fabric propensity to surface pilling, fuzzing or matting Part 3: Random tumble pilling method1 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 is app

34、licable 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 indispensable fo

Fuzz

41、e apparatus shall include:5.1.1 Device, consisting of one 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

42、 200 rpm (see Figure 2). This device shall have a mean capable 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

43、 2, which can move physically jammed test specimens from 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 wi

44、dth of the polychloroprene liner shall be such that it fits 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

46、erver does not look directly into the light. The illuminant 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.2 ISO 2014 All rights reservedBS EN IS

The photo
