Problems solved by technology

[0003] Existing testing devices for air permeability of textiles generally use the air flow through the fabric to test the air permeability, but the existing monitoring mechanism cannot seal the testing position before testing the fabric, resulting in air leakage, affecting the detection accuracy, and Unable to smooth the fabric, wrinkled fabric also affects the accuracy of air permeability detection, and the degree of automation is low
[0004] Therefore, it does not meet the existing needs, and we propose a textile air permeability tester to solve the above problems

Abstract

The invention discloses a textile air permeability tester, which comprises a mounting base, a processing table is fixedly connected to the middle position of the top of the mounting base, a ventilation slot is opened in the middle position of the processing table, and the upper surface of the processing table is A sealing groove is provided on the outer edge of the vent hole, and the top of the installation base is fixedly connected to the limit housing relative to the upper position of the processing table. The top of the limit housing is fixedly equipped with a hydraulic cylinder. The bottom extends to the inner cavity of the limit housing, and a sealing cover is fixedly installed on the bottom. When the spur rack moves upward, it drives the first gear to deflect counterclockwise, and then drives the pointer to deflect on the outer wall of the dial. Since the sealing cover and the limit housing are both transparent structural materials, by directly observing the deflection angle of the pointer on the outer wall of the dial The air pressure value entering the inner cavity of the sealed cover can be directly read, and then the air permeability of the fabric can be obtained indirectly.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a textile air permeability tester. Background technique [0002] Air permeability is a physical index that characterizes the permeability of air in the tested sample, mainly for porous materials and other materials with large air permeability, such as textiles, sponges, leather, etc. For fabric materials, the air permeability is related to the number and size of warp and weft yarn gaps and fiber gaps in the fabric, warp and weft density, yarn twist, fiber properties, yarn structure, fabric thickness and other factors. [0003] Existing testing devices for air permeability of textiles generally use the air flow through the fabric to test the air permeability, but the existing monitoring mechanism cannot seal the testing position before testing the fabric, resulting in air leakage, affecting the detection accuracy, and The fabric cannot be smoothed, and the wrinkled fabric also a...
