Trapezoidal thread serves the purpose of producing linear motion when rotated

BS 5421-2 also defines a method intended to determine the amount of staining caused to adjacent textile materials and the amount of discolouration of a polyurethane thread when it is washed in water containing dissolved copper salts This test has only a comparative value and may not indicate the exact performance of a thread in service because of the wide variation of copper contents of domestic water supplies
