Abstract
Detergent contains amphiphilic molecules which diminish the surface tension of water and are widely used for industrial purpose especially during the pretreatment of fabric. When the wastewater containing industrial detergent is discharged into different water sources, it may cause detrimental effect to the aquatic environment. This research paper focuses on the comparative study of natural detergent (soapnut/reetha) and synthetic detergent in case of 100% cotton single jersey knit fabric. Experiments were done using the different concentration of soapnut and at 10% soapnut concentration, weight loss percentage and absorbency of natural detergent scoured fabric were found almost similar to that of fabric scoured with the synthetic detergent. Moreover, bursting strength of fabric scoured with soapnut was found higher than that of synthetic detergent scoured fabric. The result derived from the experiment suggest that soapnut has remarkable detergency properties and can be used as an environment-friendly alternative to synthetic detergent.
Highlights
Textile industry involved with the various processing of fabric which needs the usages of a lot of water along with energy and most importantly harsh chemicals [1]
It can be observed that the weight loss% of knit fabric scoured with 2%, 4%, 6% and 8% soapnut was less than the weight loss% of the fabric scoured with synthetic detergent
The weight loss percentage for knit fabric, scoured with 10% soapnut was greater than the weight loss% found from the knit fabric scoured with synthetic detergent
Summary
Textile industry involved with the various processing of fabric which needs the usages of a lot of water along with energy and most importantly harsh chemicals [1]. It needs a lot of synthetic chemicals, which are toxic and detrimental to the environment and human skin [6]. These chemicals used in pre-treatment have very harsh consequences especially in terms of the high amount of chemical oxygen demand (COD), biological oxygen demand (BOD), pH and toxicity [7,8]. For that reason, being environment concern researchers are trying to make the textile wet processing eco-friendly and sustainable [9]
