Abstract

The purpose of the invention is to provide a method for detecting the warp crimp degree of dipped canvas. The method uses the crimping instrument, select the warp yarn of the dipped canvas, and firstmark a length L0. The left end of the length marked by the yarn sample is clamped in the holder, and the right end is suspended by the guide wheel. And the weight is hung, so that the warp yarn is elongated, the elongation length L is recorded. Then the method repeat the measurement of the elongation length L of the five warp yarns of the dipped canvas, calculate the arithmetic mean of L (img file='DEST_PATH_IMAGE002.TIF' wi='9' he='14' / ), and by the formula (img file='DEST_PATH_IMAGE004.TIF' wi='118' he='42' / ) calculate the warp crimp degree C. The calculated warp crimp degree can accuratelyand effectively reflect the warp crimp degree of the dipped canvas, which is suitable for testing.

Description

technical field [0001] The invention relates to the field of dipped canvas detection, in particular to a method for detecting the warp curl of the dipped canvas. Background technique [0002] Dipped canvas is used as the skeleton material of the fabric core rubber conveyor belt. Its longitudinal curl is closely related to the bending and wrinkling of the conveyor belt, which directly affects the service life of the multilayer conveyor belt. For the detection of the warp crimp of dipped canvas, there is no corresponding national standard at present. Enterprises usually conduct testing according to self-made methods, but the testing methods and testing equipment levels are different among enterprises, and the results of warp curl degree detected are very different. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for detecting the warp crimp of dipped canvas. Using a crimp meter, select the warp yarn of dipped ...
