Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Efficacy of kinnow peels extract for microbial resistance on cotton fabric
    (CCSHAU, 2018) Poonia, Neenu; Vivek Singh
    Considering the significance of anti-microbial textiles, the kinnow peels extract finish was prepared and applied on cotton fabric. Efficacy of finish against anti-bacterial activity and washing was analyzed. The effect of finish and washing on physical properties of finished fabric and washed durability of finished fabric was also assessed. Extraction of kinnow peels was conducted by soxhlet method using optimized air dry powder weight and time-period The three concentrations 1mg/ml, 3mg/ml and 5mg/ml were tried for anti-bacterial activity against Bacillus spp. The 5mg/ml concentration exhibited strong zone of inhibition was selected for further research work. The kinnow peels extract was applied on woven cotton fabric by exhaust and pad dry cure method with 5g/l concentration. The anti-bacterial finish with 5g/l concentration of kinnow peels extract with dilution factor (107 and 108) was found cent percent effective after 24 hours of inoculation of Bacillus spp. After 24 hours percent bacterial reduction gradually decreased and after 96 hours, it reduced to 90.60% by exhaust and 96.78% by pad dry cure method. The kinnow peels extract finished samples exhibited cent percent wash durability after 24 hours of inoculation (one wash). After 24 hours, it gradually decreased and after 96 hours it reduced to 90.52% by exhaust method and 95.80% by pad dry cure method. Thus, there was continuous decrease in the anti-bacterial activity with an increase in incubation period after washing but even then the anti-bacterial finish was actively retained in washed samples after 96 hours. The cotton fabric samples finished by pad dry cure method exhibited higher anti-bacterial activity and wash durability as compared to exhaust method. There was remarkable increase in fabric count, weight per unit area, thickness, bulk, elongation, bending length and flexural rigidity and decrease in tensile strength, air permeability and moisture regain after the application of finish. After washing elongation, air permeability and moisture regain increased, while decrease in fabric count, weight per unit area, thickness, bulk, bending length and flexural rigidity tensile strength decreased. Almost similar trend was found in cotton fabric samples finished by pad dry cure method but samples finished by pad dry cure method exhibited more percent change as compare to sample finished by exhaust method. Conclusively, the kinnow peels extract finished fabrics exhibited excellent efficacy against anti-bacterial activity and washing.
