Partial Correlation Analysis of Color Reflectance of Dynamic Moisture Transfer of Fabric and Static Physical Indicators of Fabric

Abstract

This article first selects the seven kinds of fabric to observe fabrics for cobalt chloride drying, moisture absorption color from blue to pink change processes, and in 0 minutes to 30 minutes seven time taking pictures of fabric. Photos of extracting the spectral photometry instrument of reflectance as the characteristic value, also measured the seven fabric static physics index, and then the reflectivity of fabric and static physical indexes of the partial correlation analysis. The results show that when Controlling the moisture content, partial correlation coefficient of the reflectivity and thermal resistance is the highest, about 0.916, the second is when the moisture vapor transmission control, partial correlation coefficient of the thickness and the reflectivity is 0.884; The moisture content and moisture vapor transmission rate, air rate and reflectivity also has certain relations, core suck height and reflectivity does not exist partial correlation relationship.

Influence of moisture content on reflectance of granular materials. Part II: optical measurements and modelling

“…Continuing this calculation, (15) as lim n→∞ f (a 0 b 2n+1 ) 1 (1−m e1 m i2 ) n+1 = 0 because 0 < m e1 m i2 < 1 and f (a 0 b 2n+1 ) is a finite number.…”

“…Colour is a complex property of materials that can in some cases be considered as a marker of another property more difficult to measure: examples can be found in the textile industry [1,2] or food industry [3,4]. In this study, presented in two parts (part I and part II, here), the aim is to show how optical measurements can help to estimate the moisture B Helene Garay helene.garay@mines-ales.fr 1 C2MA -Ecole des mines d'Alès, 6 avenue de Clavières, 30319 Ales Cedex, France content of granular materials.…”
