Since, the production process of naturally colored cotton skips the most polluting activity (dyeing) of the textile product manufacturing. As the world is moving towards to the pollution-free organic textiles and products, the naturally colored cotton fiber is going to be the next buzz word in the textile market. One of these promising approaches is to promote the usage of naturally colored cotton fiber usage and its production. There are some new considerable efforts for reducing the ecological hazard and waste generated during textile processing or developing sustainable and green materials. Dyeing processes may cause environmental pollution due to its chemical dyestuff and dyeing process auxiliary usage. Processing of fibers into textile materials requires the usage of extensive water, energy, chemical and other related resources. The parameters affecting subjective sensation are as follows: roughness ( z) and τ1, delay time of the first peak, decrease the sensations of “clarity,” “sharpness,” and “smoothness” fluctuation strength (z) promotes “smoothness” for 50 dB sounds and τe, related to reverberation, increases “pleasantness” for 50 dB sounds. pleasant.” The fabric sounds having the same SPL varied in magnitude of perception for each sensation, thus revealing the effects of secondary sound factors. These were compared with subjective ratings using seven pairs of descriptors: “hard vs. Objective sound data were obtained with psychoacoustic measurements such as Zwicker's parameters and auto correlation function parameters. This study aimed to analyze the secondary sound factors that differentiate sensations of fabric sounds at given sound pressure levels (SPL) corresponding to loudness. In fabric sound research, loudness has been proven to be the primary factor determining auditory sensation while other factors have not received enough attention in relation to their significance.
