This International Standard specifies a method for the determination of the direction of twist in single yarns and the amount of twist, in terms of turns per unit length, by the indirect untwist\/retwist method.<\/p>\n

This International Standard is applicable to single spun yarns.<\/p>\n

This International Standard is not applicable to:<\/p>\n

    \n
  1. \n

    open-end spun yarns;<\/p>\n<\/li>\n

  2. \n

    false twist and self twist yarns;<\/p>\n<\/li>\n

  3. \n

    air-jet yarns;<\/p>\n<\/li>\n

  4. \n

    yarns that stretch more than 0,5 % when the tension increases from 0,5 cN\/tex to 1,0 cN\/tex.<\/p>\n

    \n

    NOTE Such yarns may be tested under special conditions of tension which are accepted by all parties interested in the test results.<\/p>\n<\/blockquote>\n<\/li>\n

  5. \n

    yarns that are too large to permit their being placed in the clamps of testing apparatus without crushing or distortion severe enough to affect the test results.<\/p>\n<\/li>\n<\/ol>\n

    The method is designed primarily for yarns in packages, but by the application of special precautions the procedures can be used for yarns taken from fabrics.<\/p>\n","protected":false},"excerpt":{"rendered":"
