Abstract

The invention discloses a method and a device for testing the infrared emission difference between the front and back of textiles. The test device includes: a bracket part, a horizontal movement part, a test part composed of an infrared light source, an upper and lower measuring arm and a sensor. The method of testing the infrared emission difference between the front and back of the textile is: fix the sample to be tested on the test board, turn on the infrared light source, realize the left and right movement of the test board through the horizontal movement part, transport the textile to the test position, and pass the upper and lower measuring arms. The sensor is used to measure the dynamic change of the infrared radiation intensity on the front and back of the textile from entering the infrared radiation area to the steady state. Through the data measured by the sensor, the direct infrared radiation intensity of the front and back sides, the infrared intensity emitted by the front and back sides, and the difference between the infrared emission intensity of the front and back sides are obtained, which can be used in the textile testing industry to realize the infrared emission of the front and back sides of textiles. A quick measure of difference.

Description

technical field

[0001] The invention belongs to the field of testing the physical properties of textiles, in particular to the field of testing the infrared emission difference between the front and back of textiles. Background technique

[0002] With the continuous improvement of people's living standards, people's requirements for clothing accessories are getting higher and higher, resulting in the functionalization of textiles becoming the mainstream of the development of the contemporary textile industry. In order to better apply new functional fabrics, such as fabrics with infrared functions, An effective detection technique is needed to test its performance.

[0003] At present, the commonly used test methods for the infrared performance of textiles include human experiment method, temperature rise method and emissivity method. The human body experiment method evaluates the infrared radiation performance of the fabric through the direct sensory experience of the weare...

Embodiment Construction

[0017] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 , 2 As shown, a device for testing the difference in infrared emission between the front and back of textiles includes a bracket part, a horizontal movement part, and a testing part. 1, the motor support plate 7 is composed of two top plate support columns 2 vertically arranged on the two corners on the left side of the long side of the bottom plate 1, and two measuring arm support columns 5 are vertically arranged at the middle position of the bottom plate 1, and the center of the measurement arm support column 5 is biased. There is a boss at the lower position, and there is a groove on the upper and lower sides of the boss. The top plate support column 2 and the measuring arm support column 5 are at the same height when the bottom plate 1 is horizontal. , the right side of the bottom plate 1 is vertically provid...
