Emissivity Measurement of Semitransparent Textiles

Emissivity of aluminium and its importance for radiometric measurement

In the article, the authors analyse features of aluminium, which are important for the noncontact measurement of the temperature. This study is based on the results of experiments, which were carried out at foreign research institutes. Rising interest of the industry in contactless measurement of foamy aluminium profiles during their production was the motivation for this article.

Light Scattering of Semitransparent Media

Emissivity: A Program for Atomic Emissivity Calculations

Simultaneous measurement of emittance, transmittance, and reflectance of semitransparent materials at elevated temperature.

A two-substrate method is developed to simultaneously determine emissivity, transmittance, and reflectance of semitransparent materials with a single measurement under the same environment at elevated temperature. The three quantities can be obtained through the emissivities of substrates and the apparent emissivities resulting from the radiance of the sample heated by substrates. The two-subst...

Study on Wicking Measurement in Thin Layer Textiles by Processing Digital Images

The purpose of this work is to assess and develop experimental techniques that allowwicking measurement over a wide range of textiles. Various kinds of fabrics, nonwoven layers and anelectro spinning nylon layer were used as the test materials. A syringe is used to drop a 0.02 g spot ofdistilled water on the sample and a digital camera to take pictures simultaneously. When the wickingprocess st...
