Description

Technical Field

[0001] The utility model relates to the technical field of fabric production equipment, in particular to a performance testing device for protective fabrics. Background Technique

[0002] A performance testing device for protective fabrics is generally a device used to evaluate and test the performance of protective clothing fabrics. These devices can be used to test various performance indicators of fabrics, such as tear resistance, tensile resistance, abrasion resistance, waterproofness, breathability, etc. By using these testing devices, manufacturers and R & D personnel can ensure that the materials of protective clothing meet the required quality standards and performance requirements.

[0003] After retrieval, the existing Chinese patent publication number is: CN220671148U, which provides a performance testing device for protective fabrics. In this patent, by rotating the second threaded rod, the second threaded rod drives the second fixed block to move in the vertical direction, so that the second fixed block contacts the fixed block, and the friction force is increased by means of the protrusions, and then the tensile test can be carried out. When performing the water seepage test, the motor drives the worm to rotate, the worm synchronously drives the worm wheel to rotate, the worm wheel synchronously drives the third threaded rod to rotate, the third threaded rod synchronously drives the pressing plate to move, and after the pressing plate moves, the fabric is extruded into the inside of the pressing groove. As water is injected into the water tank through the water pump, the water seepage performance of the fabric is tested. After the test is completed, by opening the baffle, the water enters the water storage tank through the drainage groove to realize circulation. Through the above structure, the continuity of the test work can be increased, and after the water seepage test, the water can be more conveniently collected and reused, reducing the waste of water resources and indirectly reducing the test cost.

[0004] Although the above patent can increase the continuity of the test work, the above performance testing device for protective fabrics still has the following problems: it cannot test the performance of protective fabrics with arbitrary lengths and thicknesses, which is easy to consume time and effort.
