Testing device for whole process of fabric moisture transmission

Abstract

The invention discloses a testing device for a whole process of fabric moisture transmission. A door is arranged on one surface of a testing box; a heat insulating material is filled between the inner wall and the outer wall of the testing box; micro holes are formed in the inner wall relative to the door; a wind direction regulation plate is arranged on the outer side; a water tank is arranged on the bottom surface relative to the inner side of the door; a bracket is arranged on the upper part of the water tank; fabric test samples are suspended on the bracket; one end of each fabric test sample is connected with a pretension machine respectively and immersed into water; one end of a water pipe is inserted into the water tank and the other end of the water pipe is connected with a water supply valve; a lifting rod is arranged on the other bottom surface relative to the inner side of the door; a camera is arranged on the lifting rod; a light source is arranged on the inner wall of the testing box; a constant-temperature control device is arranged on the outer side of the top surface of the testing box; the constant-temperature control device is connected to the micro holes in the inner wall through pipelines and the wind direction regulation plate; wind outlets are formed below the micro holes; and an instrument operating console is arranged right above the constant-temperature control device. The device has the advantages that: the automation degree of continuous test on the fabric moisture transmission is high, test data are accurate and reliable, an independent constant temperature testing environment is available and applicability is high.

Description

technical field [0001] The invention relates to a fabric testing device, in particular to a fabric testing device for the whole process of wet transfer. Background technique [0002] Fabric wet transfer is a complex dynamic process. At present, the test methods for fabric wet transfer mainly include: vertical wicking method, fabric surface drop method, water retention method, vertical water absorption method, sedimentation method, etc. Among them, the vertical wicking method is a widely used method for testing the wet transfer of fabrics. The method test equipment such as figure 1 As shown, the fabric sample holder 1 clamps the fabric sample 2, and the fabric sample 2 is about 300mm long and not less than 30mm wide. The upper end is clamped by the sample gripper, and the pretensioner 5 with a weight of 3 g gives the pretension to the straightened fabric sample at the lower end, and then the lower end of the fabric sample is placed in the water of the water tank 4, and whe...

Problems solved by technology

[0004] (2) The manually read fabric wicking height is read dynamically, with large errors and large dispersion;

[0005] (3) Due to the manual reading of the fabric wicking height, less test data is obtained within the specified test time, especially when the initial stage of fabric wet transfer is 10s and 30s, it is very difficult to manually read the data;

[0006] (4) Due to the manual reading of the fabric wicking height, it is more difficult to obtain test data when multiple fabrics are tested at the same time

The fabric wet transfer test method is simple and the data is reliable, but the device for continuous acquisition of fabric wet transfer images by CCD technology is only suitable for the verification of the above method, and a specific constant temperature environment is required to meet the environmental requirements of the fabric wet transfer performance test
