An apparatus for quantification of light and temperature cutting ability of curtains

Abstract

An apparatus has been designed and developed to measure the light cutting/absorbing ability of curtains and to provide useful information on their temperature cutting ability. The apparatus is provided with various light sources with light, temperature and humidity detectors. The reproducibility of results, and effect of intensity of light (MBTL light source) on light and temperature cutting ability of six different fabric samples have been studied. The light and temperature cutting ability of the knitted fabric is found to be lower than that of woven and black out curtain fabric samples.
