Description

Technical Field

[0001] The utility model relates to the technical field of water permeability detection devices, in particular to a water permeability testing device for waterproof fabrics. Background Art

[0002] In order to detect the waterproof performance of fabrics during the production process, some waterproof performance tests are usually carried out, including hydrostatic pressure test, spray test and water vapor transmission rate test. The spray test is to place the test absorbent paper behind the fabric first, and then use a machine to spray the fabric with test water. The waterproof performance of the fabric is obtained by weighing the weight change of the absorbent paper before and after the test.

[0003] During the test, the existing waterproof performance testing device simply covers the test fabric on the test absorbent paper, and then clamps the two ends of the fabric with the clamps on the left and right ends. This will result in the fabric and the test paper not being sealed on all sides during the test, causing the spray water to soak the test absorbent paper from the upper and lower ends of the test paper, resulting in deviations in the test results, which ultimately affect the test results.

[0004] Therefore, it is necessary to provide a new waterproof fabric water permeability testing device to solve the above technical problems. Utility Model Content
