20、ENISO129451:2000 ISO -549211:(0002E)iii Foreword ISO (the International Organization for Standardization) 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 bo
21、dy interested in a subject for which a technical committee has been established has the right to 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 Electrot
22、echnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pu
23、blication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 12945 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all s
24、uch patent rights. International Standard ISO 12945-1 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 24, Conditioning atmospheres and physical tests for textile fabrics. ISO 12945 consists of the following parts, under the general title Textiles Determination of fabric prop
25、ensity to surface fuzzing and to pilling: Part 1: Pilling box method Part 2: Modified Martindale method Part 3: Determination using a random tumble method Annex A of this part of ISO 12945 is for information only. ENISO129451:2000 ISO -549211:(0002E) iv Introduction Pills are formed when fibres on a
26、 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 type and fabric end use. Generally the level of pilling which develops is determined by the
27、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 and fabric properties. Examples of extreme situations are found in fabrics containing s
28、trong 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. With a weak fibre the rate of pill formation competes with the rate of wear-off. This w
29、ould result in a fluctuation of pilling with an increase of wear. There are other constructions in which 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 tes
30、t 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 been established in which fabrics can be ranked in the same order of fuzzing and pill
31、ing propensity as is likely to occur in end-use wear. Particular attention is drawn to annex A which gives advice on the maintenance of the apparatus. It is recommended that annex A be studied prior to carrying out the procedure. ENISO129451:2000 INTENRATIONAL TSANDADR ISO -549211:(0002E)1 Textiles
32、Determination of fabric propensity to surface fuzzing and to pilling Part 1: Pilling box method 1 Scope This part of ISO 12945 describes a method for the determination of the resistance to pilling and surface change of textile fabrics. 2 Normative reference The following normative document contains
33、provisions which, through reference in this text, constitute provisions of this part of ISO 12945. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 12945 are encouraged to investigate the
34、 possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 139, Textiles Standard atmos
35、pheres for conditioning and testing. 3 Terms and definitions For the purposes of this part of ISO 12945, the following terms and definitions apply. 3.1 fuzzing roughing up of the surface fibres and/or teasing out of the fibres from the fabric producing a visible surface change NOTE This change can o
36、ccur during washing, dry cleaning and/or wearing. 3.2 pills entangling of fibres into balls (pills) that stand proud of the fabric and are of such density that light will not penetrate and will cast a shadow NOTE This change can occur during washing, dry cleaning and/or wearing. 3.3 pilling generati
37、on of pills over the surface of the fabric ENISO129451:2000 ISO -549211:(0002E) 2 4P r i n c i p l e Specimens are mounted on polyurethane tubes and tumbled randomly in a cork-lined box at a constant rotational speed. Fuzzing and pilling is assessed visually after a defined period of tumbling. Any s
38、pecial treatment of the laboratory sample, i.e. washing, cleaning, has to be agreed upon and shall be stated in the test report. 5 Apparatus 5.1 Pill testing box, cubic, with internal dimensions, before lining, of 235 mm. All internal surfaces of the box shall be lined with cork jointing material of
39、 3,2 mm thickness. The box shall be rotated at (60 2) r/min about a horizontal axis passing through the centres of two opposite faces. One side of the box shall be removable for access. NOTE Advice on the calibration and comparison of pill testing boxes is given in annex A. Cork linings shall be ins
40、pected at regular intervals and shall be replaced when obviously damaged or soiled in such a way as to alter their frictional properties (see A.4). 5.2 Polyurethane specimen tubes, (four are required), each measuring (140 1) mm in length by (31,5 1) mm outside diameter by (3,2 0,5) mm wall thickness
41、, mass (52,25 1) g. 5.3 Mounting jig, used to mount specimens on the tubes. 5.4 Self-adhesive polyvinyl chloride (PVC) tape, 19 mm wide. 5.5 Sewing machine. 5.6 Viewing cabinet, illuminated by a white fluorescent tube or bulb (the colour temperature of the light source is not critical) to give unifo
42、rm illumination over the width of the specimen(s) and masked in such a way that the observer does not look directly into the light. Position the illuminant at an angle between 5 and 15 to the plane of the specimen (see Figure 1). The distance between the eye and the specimen shall be between 30 cm a
43、nd 50 cm for normal corrected vision. Key 1 Light source 2 Observer 3 Specimen Figure 1 Illumination of specimens ENISO129451:2000 ISO -549211:(0002E)3 6 Conditioning and testing atmosphere The standard temperate atmosphere for conditioning and testing textiles as defined in ISO 139 shall be used, i
44、.e. a temperature of (20 2) C and a relative humidity of (65 2) %. 7 Preparation of test specimens 7.1 Pretreatment Unless otherwise agreed, launder or dry clean the sample using a method agreed between the interested parties. NOTE 1 The procedures described in ISO 6330 or ISO 3175-1 and ISO 3175-2
45、may be suitable. NOTE 2 It is recommended to launder or dry clean test specimens in order to protect the friction surfaces of the pilling box and specimen tubes from lubricants or finishes which may cause inconsistent results. If laundering or dry cleaning is carried out, assess the specimens before
46、 and after the pretreatment using the grading scheme described in clause 9. 7.2 Cutting out From the sample, cut four test specimens, each 125 mm 125 mm. On each test specimen mark the back of the fabric and the length direction. Where a fabric has no discernible face, test both sides. An additional
47、 cut specimen of 125 mm 125 mm is required for assessment. NOTE Test specimens should be randomly placed with none of the test specimens having common warp or weft threads. 7.3 Number of test specimens Take two specimens and fold each with its face, if discernible, inward and with the machine direct
48、ion running in the direction of the fold. Sew 12 mm from the cut edges to form a tube, using a stitch density such that a balanced seam is produced. Prepare the other two specimens similarly with the cross direction running in the direction of the fold. 7.4 Mounting of test specimens Turn each specimen inside out, so that the fabric face forms the outside of a tube, and cut 6 mm off each end of the fabr
