Preparation of microcrystalline cellulose using cotton yarn waste from the textile industry and evaluation of its characteristics

In order to protect the environment and cellulose resources, yarn wastes from textile industry, which contains a considerable amount of cellulose, can be used produce microcrystalline cellulose. this study, waste was milled via ball mill subjected acid hydrolysis using sulfuric hydrochloric at different times. It characterized through various tests determine particle size, degree polymerization, bulk tap density, water soluble substances, ash content, moisture absorption capacity, infrared spectroscopy, X-ray diffraction, thermogravimetric analysis. The Fourier-transform spectroscopy analysis showed that chemical compositions all samples were same. diffraction measurement an increase in crystallinity after hydrolysis. prepared had good temperature resistance. results obtained cotton textiles able pharmacy standard level.
