PART 1: MARTINDALE ABRASION TESTING APPARATUS[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_tta_tabs][vc_tta_section title=”OBJECT AND SCOPE” tab_id=”1686214240101-556b0dc0-8de6″][vc_column_text woodmart_inline=”no” text_larger=”no”]This part of ISO 12947 specifies requirements for the Martindale abrasion apparatus and auxiliary materials to be used in the test methods specified in parts 2 to 4 of ISO 12947 for the determination of strength to fabric abrasion.<\/p>\n

This part of ISO 12947 applies to the following fabric testing devices:<\/p>\n

    \n
  1. a) Openwork and knitted fabrics;<\/li>\n
  2. b) Pile fabrics where the pile height is less than or equal to 2 mm;<\/li>\n
  3. c) Nonwoven.<\/li>\n<\/ol>\n

    1 Abrasive Friction: Complete revolution of the two outer transmission elements of the Martindale abrasion tester.<\/p>\n

    2 Abrasion cycle: execution of all the abrasive movements in translation which form a Lissajous curve comprising 16 frictions, i.e. 16 cycles of the two external transmission elements, and 15 cycles of the internal transmission element of the device test. Martindale abrasion.<\/p>\n

    3 Control interval: Number of continuous rubbings.<\/p>\n

    4 Lissajous Curve: A curve generated by motion that starts out as a circle and gradually becomes ellipses that narrow to a straight line, from which ellipses widen further and further in opposite directions diagonally, before to repeat the drawing again.<\/p>\n

    5 Workstation: Abrasion plate[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”PRINCIPLE OF THE METHOD” tab_id=”1686214270856-e449c106-c4de”][vc_column_text woodmart_inline=”no” text_larger=”no”]A circular specimen is subjected, by means of the Matindale abrasion tester, to a defined load and to the action of friction with an element, according to a translational movement forming a Lissajous curve.<\/p>\n

    At the same time, the sample holder, provided either with the sample or with the abrasive element depending on the method used, rotates freely around its own axis, perpendicular to the horizontal plane.<\/p>\n

    The specimen is subjected to abrasive wear during a previously determined number of rubs.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”EQUIPMENT” tab_id=”1686237129544-82a203f0-2905″][vc_column_text woodmart_inline=”no” text_larger=”no”]The test apparatus is composed of a support plate which carries the abrasive plates and the transmission mechanism,<\/p>\n

      \n
    1. Abrasive: plain woolen fabric against which the specimen is abraded (according to Table 1).<\/li>\n
    2. Felt: Woven wool felt lower discs (according to table 2)<\/li>\n
    3. Foam: Bottom support for the specimen or for the abrasive mounted on the specimen holder (according to table 3)<\/li>\n<\/ol>\n
