Yarn strength measurement method

Abstract

The invention provides a yarn strength measurement method. The measurement method comprises steps as follows: yarn is put on a pulling device and pulled with the pulling device, and the maximum tension of the pulled yarn is detected with a stress sensor; a yarn material is mounted on the pulling device, water is sprayed to the surface of the yarn material, the yarn is pulled with the pulling device after the yarn is wetted, and the maximum tension of the wetted yarn is detected with the stress sensor; the yarn is sent to a baking oven to be heated and then mounted on the pulling device, and the strength of the heated yarn is detected with the stress sensor. The strength of normal yarn, wetted yarn and high-temperature yarn is sequentially tested, the yarn in different work environment is detected, the accuracy of the detection result of the yarn is improved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of yarn dyeing, in particular to a method for measuring yarn strength. Background technique [0002] At present, when measuring the yarn strength, the yarn is usually pulled by a pulling device, and the maximum pulling force before the yarn breaks is detected by a force sensor, but the yarn strength is currently being measured When using yarn, it is usually to detect the yarn at room temperature and dry, but when using the yarn, due to different usage conditions, such as high temperature or humid environment, the strength of the yarn is prone to fluctuations, resulting in the inability to accurately know the yarn strength. strength. Therefore, it is particularly important to solve the problem that the yarn strength is different and difficult to detect under different environments.
