Abrasion tester and abrasion test method of dynamically stretched weaving size film

Abstract

The invention relates to an abrasion tester and an abrasion test method of a dynamically stretched weaving size film. The device comprises a size film stretching device, a grinding head, a grinding head positioning device, a reciprocating traction device and a detection counting device on a machine base, wherein a size film sample is driven by the size film stretching device to make stretching motion; and the size film sample is driven by the reciprocating traction device to make reciprocating friction motion relative to the grinding head, so that the actual operating environment of the size film on a weaving machine is simulated really, and an abrasion test of the dynamically stretched size film at a certain frequency is realized. The abrasion tester and the abrasion test method not onlycan acquire the abrasion performance of the dynamically stretched and deformed size film by friction frequency recorded by the detection counting device during the abrasion of the size film sample, but also can preset the friction frequency; and after the device automatically stops abrasion motion, the abrasion performance of the dynamically stretched and deformed size film is acquired according to the abrasion condition of the size film sample so as to judge whether the size film meets the requirement of the actual weaving process or not.

Description

technical field [0001] The invention relates to the technical field of warp yarn sizing performance testing, in particular to a device and method for a textile size film wear test under dynamic tension conditions. Background technique [0002] The sizing agent forms a firm and complete sizing film on the surface of the warp yarn, which has a great relationship with the application of hairiness and the improvement of the wear performance of the warp yarn. When the size film is woven on the loom, it is subject to the comprehensive action of repeated stretching and abrasion of 3000-5000 times. Under the action of this complex mechanical force, if the size film is severely worn, the proper protective film will not be achieved. The surface hairiness of the warp yarn will be prominent, the yarn body will be fluffed, and in severe cases, there will be problems such as fiber dissociation, yarn disintegration, and end breakage. Defects are not conducive to the normal progress of the...

Problems solved by technology

However, the current devices and methods are all carried out under the condition that the size film is not subjected to repeated dynamic stretching, and cannot truly simulate the wear state of the size film during actual operation, so there is a large deviation between the test results and the actual situation
