Assessment of the Barrier Performance of the Flourosilicone Treated Fabric Exposed to Pesticides Spraying to Chilli Crop at Laboratory Conditions

In this study, in view of development of protective clothing for pesticide sprayers in chilli crop, the suitable fabric polyester 67/cotton 37 with weight 157.7 GSM was selected. BOND-WR-12-A RTU was aqueous fluorosilicone durable water and oil repellent emulsion was used to treat the fabric by using different application parameters at the rate of 5 per cent concentration. As per Chowdhury, 2018 water repellent finish type and concentrations were very important parameters to obtain water repellent fabric having acceptable use properties. Later, the treated fabric was exposed to the selected pesticides like Phosphamidon, Monocrotophos and Dimethoate for for three exposures. By estimating the absorption and penetration behaviour of the treated and untreated fabrics, the performance of silicon finish was determined by using four factor with CRD and Heuristic method. From this result, the treated fabric had restricted the absorbency over control fabric and the Studies on barrier clothing, [1,2] suggested that blends of polyester cotton and polyester viscose showed better barrier performance with minimum penetration of pesticides than other blended fabrics. Hence it can be used in development of protective clothing for pesticide applicators in chilli crop or any other field crops where ever pesticides are used.
