Textile optical performance test system based on linear gradient filtering piece

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...
