Problems solved by technology

The above methods have the following deficiencies in the testing of the optical properties of textiles: (1) only the research on a certain aspect of the optical properties of textiles, such as the testing and characterization of only a single effect of ultraviolet light, visible light or infrared spectrum; or limited to general applications. Study of light reflection, light absorption and light transmission properties
(2) The test instruments mostly use commercial spectrophotometers or radiation intensity meters. Since they are not designed for performance testing of textiles, they bring problems such as inconsistency in test results of different instruments for the same sample, and slow test speed.

Embodiment Construction

[0012] As shown in Figure 1, the light source 1 emits light with a wide spectrum including ultraviolet, visible and infrared, and the parallel light after passing through the first collimator 4 is incident on the beam splitter 2 and then divided into two paths, and the reflected light from one path is incident as the reference light 5 to the first linear gradient filter 9, converted into an electrical signal by the first photodiode array detector 10, and connected to the first signal processing circuit 11; the other transmitted light is irradiated on the tested textile sample 3 as measurement light, and is The second light reflected by the textile sample 3 passes through the collimator 4' to form a reflected parallel light 6, and the reflected parallel light enters the second linear gradient filter 9' and is converted into an electrical signal by the second photodiode array detector 10' , connected to the second signal processing circuit 11'; the light passing through the teste...

Abstract

The invention discloses a textile optical property testing system based on linear gradation filter, which is composed of a light source, a collimator tube, a spectroscope, a linear gradation filter, an opto-electrical diode array detector, a signal processing circuit and a computer. The system utilizes the advantages of linear gradation filter having simple and compact structure, wide continuous spectrum and good thermal stability, which can finish the light splitting of each spectrum section. The test result can effectively reflect the reflection, transmission, adsorption and other performances. The invention is mainly suitable for testing the reflection, transmission, adsorption and other performance of dress textile, decoration textile and industry textile to various lights.

Description

technical field [0001] The invention relates to a textile optical performance testing system based on a linear gradient filter. Background technique [0002] The optical properties of textiles are an important part of textile properties. Now physical and chemical analysis instruments based on optical principles are applied to the textile industry, providing an analytical basis for qualitative and even quantitative analysis of the reflection, absorption and transmission characteristics of textiles to light of different spectral wavelengths. At present, the commonly used test methods mainly include visual method, spectrophotometer method, radiation intensity accumulation method, illuminance meter method and so on. The above methods have the following deficiencies in the testing of the optical properties of textiles: (1) only the research on a certain aspect of the optical properties of textiles, such as the testing and characterization of only a single effect of ultraviolet l...
