ABSTRACT
The study was conducted at the Micro-fiber Testing Laboratory, Mogbazar, Dhaka, Bangladesh in 2009. Single jersey cotton knitted fabric is one of the most used knitted fabrics in the clothing sector. For this study single jersey cotton knitted fabric was taken. The sample was dematerialized using acetic acid and hydrochloric acid. Demineralization was done at four different pH value (3.5, 4, 4.5 and 5) using both acetic acid and hydrochloric acid. For measuring demineralization effect total hardness of the liquor at different pH has been measured and compared.
Keywords: Demineralization, Acetic acid and Hydrochloric acid.
