21、 bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organiza
22、tions, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in t
23、he ISOAEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that
24、some of the elements of this part of IS0 12945 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 12945-1 was prepared by Technical Committee ISOKC 38, Textiles, Subcommittee SC 24, Conditioning atmospheres
25、 and physical tests for textile fabrics. IS0 12945 consists of the following parts, under the general title Texti/es - Determination of fabric propensity to surface fuzzing and to pilling: - Part 1: filling box method - Part 2: Modified Martindale method - Part 3: Determination using a random tumble

Such surface deterioration is generally und
27、esirable, 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 entanglement leading to pill formation; b) developmen
28、t 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 consequence of the strong fibre is a rate of pill fo
29、rmation 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 wear. There are other constructions in which
30、the 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 same factor and would be universally a
31、pplicable 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 attention is drawn to annex A which give
32、s advice on the maintenance of the apparatus. It is recommended that annex A be studied prior to carrying out the procedure. iv STDaBSI BS EN IS0 L2945-L-ENGL ZOO description of the laboratory sample; where applicable, details of pretreatment of the laboratory sample; number of test specimens and nu

34、e of the pill testing box A.l Pill testing box The rotational speed of (60 k 2) r/min should be checked periodically. New liners require running in for approximately 200 h with four blank tubes until the liner has stopped shedding cork dust. Generally, the frictional properties of the cork are not a
35、 major source of test result variation, but after prolonged use the surface of the cork may become polished or contaminated. Such changes can lead to less severe pill testing. In such cases, the cork liners should be replaced. A.2 Specimen tubes The press-moulded polyurethane tubes should be identic
36、al to each other when new. Experience of intensive use has shown that no significant wear of these tubes occurs under normal use conditions. The most critical pari of the tube is the convex outer surface at its end. New tubes should be checked on receipt in order to ensure that no moulding faults ha
37、ve occurred in the critical region. In-use damage is unlikely, but if it should occur it is essential that the tube be replaced. A.3 Cleaning and maintenance Before each test it is essential to ensure that all fluff and debris from the previous test have been removed from inside the box, e.g. by mea
38、ns of a vacuum cleaning device or by using a painters small brush. Periodically, it may be necessary to clean the cork liners if they have become contaminated by finishes etc. from test fabrics. A suitable cleaning solvent is industrial methylated spirit. Use only a minimum amount of solvent to wipe
39、 the surface of the cork. NOTE The use of industrial methylated spirit may be the subject of national legal regulations. A.4 Calibration It is recommended that each user of this test method retain two calibration fabrics relevant to the work of the laboratory and having different levels of pilling a
40、nd fuzzing in the range grade 1-2 to grade 4. These calibration fabrics should be used to test every newly installed box and every newly relined box and the tested fabric specimens should be retained for subsequent reassessment. At regular intervals, e.g. 6 months, the calibration fabrics should be
41、retested and compared with the initially tested specimens. In this way any drift, either between boxes or within a box, can be detected. The fact that specimens may have a slightly flattened surface should be taken into account. 6 STD.BS1 BS EN IS0 L29Y5-L-ENGL 2001 Lb24bb 090L5bb 577 W EN IS0 12946
