Abstract: The light transmittance behaviour of four different coloured curtain fabrics has been studied under natural lighting conditions (morning, afternoon and evening). The intensity of incident sunlight and transmitted light from the samples are measured using Luxmeter, in an enclosed black chamber. The percentage of transmitted light is calculated with reference to the incident sunlight, to study the influence of colour and number of fabric layers. It is observed that the transmittance behaviour of curtain fabrics is highly influenced by its colour due to the spectrum of colours, which is followed by the influence of number of layers and sunlight conditions. Further, the transmittance % of curtain is also influenced by the wavelength of incident sunlight.
