Device and method for measuring yarn drape

Abstract

The invention discloses a yarn draping degree measuring device and a method. The yarn draping degree measuring device comprises a left test mechanism, a yarn, and a right test mechanism. The left test mechanism comprises a bottom plate A, a prop rod A, a cylinder, a pressure regulating valve, and a guide wheel. The guide wheel, the cylinder and a bracket plate are installed on the front surface of the prop rod A in sequence from top to bottom. The method for conducting an experiment using the yarn draping degree measuring device comprises the following steps: S1, experimental installation of a yarn on the device; S2, cylinder pressure regulation; S3, conduction of a yarn draping degree measuring experiment; and S4, measurement and record of the draping degree of the yarn. The device and the method have the beneficial effects of simple structure, convenient operation, labor saving, and high measuring accuracy.

Description

technical field [0001] The invention relates to a yarn drape measuring device and method. Background technique [0002] The drape of the cord is the difference between the length of the longest yarn and the shortest yarn after the unit length of the cord is untwisted into a single yarn. It is an important technical index to measure the uniformity of tension between the single yarns of the rope, and it involves the strength retention rate of the single yarns after they are combined. [0003] At present, some patents have appeared on special equipment for measuring the degree of drape of wire ropes. The Chinese patent "Wire Rope Drape Meter (Patent No.: CN200420078799.8)" discloses an instrument for measuring the wire rope drape, which can achieve the purpose of measuring the wire rope drape within the scope of its technical field. It mainly includes a twist tester and a thickness meter reading device, and its technical effect is: the wire rope drape meter is reasonable in d...

The Chinese patent "Wire Rope Drape Meter (Patent No.: CN200420078799.8)" discloses an instrument for measuring the wire rope drape, which can achieve the purpose of measuring the wire rope drape within the scope of its technical field. It mainly includes a twist tester and a thickness meter reading device, and its technical effect is: the wire rope drape meter is reasonable in design and easy to operate. Through the setting of the tension trimmer 6, the elasticity of the wire rope can be controlled with a known given tension. Deformation improves the reproducibility and comparability of the experimental results, increases the accuracy of the measurement results, and greatly reduces personal errors, but its disadvantage is that the amount of manual operation is large, and the adjustment of the tension is based on weights. The general adjustment range Limited or large adjustment gap, certain measurement accuracy but not enough

In the current test, the measurement error caused by manual stretching is large, and many people need to measure the drape of the yarn, which is not conducive to the measurement of the drape of the yarn.
