  Morarjee is one of the leading players in the premium cotton shirting fabric and high fashion printed fabric segments. Morarjee’s subsidiary company, Integra Apparels and Textiles Ltd, specialises in readymade garments. Both companies sell their products globally and are extremely quality conscious.
BackgroundFinished fabrics are washed in a print washer manufactured by Texfab, which carries out a multi-stage washing process. First the fabric passes through a bath of caustic solution, which is alkaline in nature, followed by a bath of acetic acid to neutralise the alkalinity in fabric, and finally into a rinsing bath. The acetic acid bath solution needs to be maintained at a precise pH level for optimum fabric washing and also to prevent damage of the fabric texture.
ChallengeThe critical part of the whole process is maintaining the permissible pH level of the acetic acid washing solution in the bath consistently and accurately based on different fabric characteristics and reactions. The usual practise by the plant operators is to measure the pH value of acetic acid bath manually and then add chemicals to get the desired recipe. It is however very difficult to maintain a consistent pH level by this method. Manual operation also leads to:• Process and production delays • Inaccurate recipes • Improper cleaning of fabric • Extra man-hours • Wastage of expensive chemicals
