Perspective on the color characteristics of cotton


General and abstract, such as the color characteristics of the provisions of the silk is good, a silk, a little silk, etc., to understand the personal side - gangs Zhaiyue Hui Xiang Ze test compared the different style, based on existing sensory test conditions, just by touch, visual and hearing is difficult to accurately grade, the same will result in different grades of cotton. Second, the standards are different in kind annually produced \Because the use of objective physical examination standards are hand-made, color more or less different. Therefore, different physical standards,[link widoczny dla zalogowanych], the same level there are some differences in color, the lack of scientific. Third, the test environment is different from the simulated daylight lighting requirements, and the colors on the indoor environment, although the relevant national standard color temperature, light intensity has a tolerance requirement, but the actual inspection, the correlated color temperature, light, small differences cotton at different angles the same color differences will appear. Fourth, the human factor is the color vision on the retina of the eye cone cell function, it is only in very bright light, the color can play a distinguished role. When less than 100 lux of illumination, some light will begin to see clear color (white background). Cotton fiber color and saturation are generally low, a slight change in depth, will have varying degrees of impact on test results. U.S. Department of Agriculture began in 1929 and measured disk color measurement color characteristics of cotton fiber in 1950 switched GARDNER Company production of \1959 U.S. SPINLAB color measurement instrument company has been improved and named the 235 cotton color measurement instrument. The early 70s and quickly prototype a color measurement instrument of cotton fiber, the early 80s and developed a 830 cotton color measurement instrument,[link widoczny dla zalogowanych], in 1984, has developed into a 930 cotton color measurement instrument, the late 90s, the further development of the company after the Swiss zellwegeruster ,[link widoczny dla zalogowanych], developed a high-precision, high-capacity HVI testing equipment. All of the above basic principles of color measurement instrument is the same, but the automation, accuracy levels have been continuously improved. This shows that detection of foreign cotton after 70 years of continuous research and development, testing technology is well established, China joined the WTO, cotton inspection techniques inevitably to -4 \4 \; -4 \4 \How to apply the luster of cotton to determine the maturity of the cotton sector is a matter of opinion review. Cotton's \Because the appearance of cotton fiber from the body look good mature cotton, cellulose gathered in numerous and homogeneous, cell wall thickness, transfer music and more. Reflect the performance of light reflected less refraction and more diffuse. Thus, maturity is a good cotton with bright light, not the dazzling light; mature poor cotton fiber cell wall by a thin,[link widoczny dla zalogowanych], small convolution, was partial band, coupled with relatively thicker waxy fat, skin, reflect the performance of light reflected from more diffuse refraction less. Therefore, poor cotton maturity is dazzling with light, bright light,[link widoczny dla zalogowanych], not soft. The different optical forms, that thorn vision expressed as \cotton inspection when these two concepts do not reversed. Some colors such as white matter of the weak with \not meeting the situation.
