Description

[Technical Field]

[0001] This invention relates to the technical field of fabric production equipment, and in particular to the technical field of a fabric air permeability testing device. [Background Technology]

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the garment. During the production and preparation process, fabrics often need to undergo functional testing to meet different technical indicators and requirements, such as waterproof testing, breathability testing, and heat insulation testing.

[0003] Breathable textiles have always been a goal, especially in hot weather, as wearing breathable clothing provides a comfortable experience. Good breathability increases heat dissipation, prevents sweat buildup, and improves comfort. Therefore, breathability is an important indicator of fabric performance, and factories need to test the breathability of their fabrics.

[0004] Most fabric breathability testing devices on the market currently use direct airflow to test the fabric, which cannot pre-treat the fabric surface. The accuracy of the test is poor when the fabric surface is covered with lint and other debris. At the same time, they cannot simulate the fabric condition under humid, high temperature and dry conditions, resulting in incomplete test data. [Summary of the Invention]

[0005] The purpose of this invention is to solve the problems in the prior art and to propose a fabric breathability testing device that can pre-clean the lint and debris on the fabric surface to ensure the accuracy of breathability testing.

The negative pressure vacuum cleaner is located outside the negative pressure suction hood. A first air permeability detection groove is located on the right side of the debris-cleaning brush roller. Several temperature sensors are installed on the inner wall of the first air permeability detection groove. An airflow detector is located at the bottom of the first air permeability detection groove, and a one-way exhaust valve is connected to the bottom of the airflow detector. A first air permeability detection upper slot is positioned directly above the first lower air permeability detection slot. A first air intake fan is mounted on the top of the first upper air permeability detection slot, and an electric heating mesh is installed at the bottom of the first air intake fan. An air inlet connected to the first air intake fan is located on the top side of the first upper air permeability detection slot, and an airflow filter is detachably mounted on the air inlet. The top of the first upper air permeability detection slot is mounted on the top of the protective housing via a first electric lifting column. A second lower air permeability detection slot is positioned to the right of the first lower air permeability detection slot, and several humidity sensors are installed on the inner wall of the second lower air permeability detection slot. The device includes an airflow detector at the bottom of the second lower air permeability detection slot, with a one-way exhaust valve connected to the bottom of the airflow detector. A second upper air permeability detection slot is positioned directly above the second lower air permeability detection slot. A plurality of atomizing water nozzles connected to a water tank are evenly arranged around the inner wall of the second upper air permeability detection slot. A second air intake fan is positioned at the top of the second upper air permeability detection slot. An air inlet connected to the second air intake fan is positioned at the top of the side of the second upper air permeability detection slot. An airflow filter is detachably mounted on the air inlet. An active winding frame is positioned on the right side of the protective housing.
