Example

[0031] first embodiment

[0032] Please refer to Figure 1-Figure 5 , the present embodiment provides a method for testing evenness of evenness, comprising the following steps:

[0033] S1. Pull out the conductive yarn 150 to be tested to the evenness testing device 100 .

[0034] Specifically, the evenness testing device 100 includes a conveying device 110 , an electrode system 120 , a data acquisition system 130 and a computer 140 . The electrode system 120 is set on the delivery device 110 , the data collection system 130 is electrically connected to the electrode system 120 , and the computer 140 is connected to the data collection system 130 by communication.

[0035] Conductive yarn 150 is different from traditional yarns. Conductive short fibers or filaments are added during the weaving process to form conductive blended yarns or pure spinning yarns. Since conductive fibers are electronically conductive, the conductive yarn 150 woven has a relatively low resistance v...

Abstract

The invention relates to the field of conductive yarn, in particular to a testing method for yarn evenness. The method comprises the following steps: firstly, pulling out conductive yarn to be testedto a yarn evenness testing device, and then connecting the conductive yarn to an electrode system; then connecting the electrode system to a data collection system which collects voltage or current signals corresponding to the conductive yarn and sends the voltage or current signals to a computer; finally, ensuring that the computer computes the yarn evenness of the conductive yarn according to the received voltage or current signals. The method provides a novel method for testing the yarn evenness of the conductive yarn, and has significant effect on the testing and research of evenness of the conductive yarn.

Description

technical field [0001] The invention relates to the field of conductive yarns, in particular to a method for testing evenness of evenness. Background technique [0002] The uniformity of thickness or weight of yarn, sliver or roving along the axial unit length is called evenness. [0003] Generally, the methods for testing yarn dryness and evenness in the prior art mainly contain the following aspects: the first, cut weighing method, the fiber is cut and weighed to measure the yarn unit length or the method of the weight of the specified length to test the yarn quality The uniformity of the yarn, the second, the capacitance method, is to use parallel plates to measure the change of the capacitance of the yarn to indirectly reflect the uniformity of the yarn thickness; the third, the illumination method, using parallel light to shine on the surface of the yarn, The shape and area of ​​the shadow formed by the shade of the yarn is measured by a photosensitive device to indire...
