Textile stretch performance test pretreatment device and pretreatment method

Abstract

The invention discloses a textile stretch performance test pretreatment device and a pretreatment method. The pretreatment device comprises a first glue storage groove, a second glue storage groove, afirst glue pushing device, a second glue pushing device, a first glue coating device and a second glue coating device, wherein the first glue pushing device moves in the extending direction of the first glue storage groove; the second glue pushing device moves in the extending direction of the second glue storage groove; the first glue coating device is communicated with the first glue storage groove; the second glue coating device is communicated with the second glue storage groove; the first glue coating device comprises a first left glue coating device and a first right glue coating device; the shape of the first left glue coating device and the shape of the first right glue coating device are respectively rectangular shapes; four adjacent vertexes between the first left glue coating device and the second right glue coating device form a rectangular shape; the second glue coating device uses the textile as the symmetrical surface to realize the mirror image symmetry with the firstglue coating device. The problems of carrying yarn pulling, structure disengagement and looseness, yarn slip motion and the like generated in the stretch performance test of great-load machine weavingstructural textile can be solved. The accurate experiment test data can be provided; the stretch performance of the great-load machine weaving structure textile can be expressed.

Description

technical field [0001] The invention relates to the technical field of textile testing, in particular to a textile tensile performance test pretreatment device and a pretreatment method. Background technique [0002] At present, due to its own advantages in performance, such as light weight and high strength, fatigue resistance, impact resistance, etc., textiles are increasingly transferred from traditional clothing to industrial textiles. Traditional clothing textiles mainly pursue the comfort, aesthetics and designability of clothing, but have lower requirements on mechanical properties, while industrial textiles, especially geotextiles, are used in harsh environments, and mechanical damage is the main failure form. Therefore, it is particularly important to measure and evaluate the mechanical properties of industrial textiles, especially geotextiles. Compared with traditional clothing textiles, geotextiles have a much stronger load-bearing capacity, so the range of tradi...

AI Technical Summary

Problems solved by technology

[0003] Woven structural textiles are mainly made of interweaving warp and weft yarns perpendicular to each other, while geotextiles are mostly made of synthetic fibers. The fiber surface is smooth and the friction is small. Under the test conditions of large loads, it is easy to pull out the yarn. and slipping phenomenon

The slipping and drawing of the yarn will directly affect the accuracy and effectiveness of the test results, resulting in distortion of the experimental data and affecting the evaluation of the tensile properties of textiles
