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.

    Effect of Enzymatic Treatment on Softening of Jute Fabric
    (CCSHAU,HiSAR, 2020-06) Jamal, Zeba; Arya, Nisha
    Jute has many beneficial properties such as high tensile strength and modulus with good dimensional stability but has some drawbacks such as harshness, poor wrinkle recovery, high fiber shedding, yellowing on exposure to sunlight, susceptible to microbial attack and less resistant to fire. The present study has been conducted to note the effects of enzymatic treatment on softening of jute fabric. Desizing and scouring was done by conventional and enzymatic method. Enzymatic desizing and scouring depicted better water absorption and weight loss, hence it was continued. Three commercial softeners and four enzymes were procured on the basis of their suitability for softening of jute fabric. Eighteen combinations of commercial softeners and 39 combinations of enzymes were tried and one top ranked combination from each category selected on the basis of preference of experts was continued for further research work. Standardization of commercial softener and enzymatic treatment for jute fabric was done on the basis of improvement in mechanical properties i.e. bending length, flexural rigidity and drape coefficient. Application of conventional chemical treatment was done by exhaust method. Application of aminosilicone softener and enzymatic treatment was done as per optimized conditions by pad dry cure method. SEM was done to understand the changes in surface morphology after each treatment. The changes in physical and functional properties after different treatments were studied. There was improvement in softness and drape after each treatment but maximum decrease in bending length (40.64 per cent in warp and 45.43 per cent in weft), flexural rigidity (86.14 per cent) and drape coefficient (30.86 per cent) was observed after enzymatic treatment. The enzymatically treated jute fabric exhibited 13 CFUs for E.coli bacteria with 95.11 per cent reduction in the growth of bacteria whereas it showed 131 CFUs for S. aureus bacteria having 88.32 per cent reduction in the growth as compared to controlled sample. It was also discerned that the UPF value of the scoured fabric was 13.07 which increased to 57.64 when treated with enzymes with very good grade under protection category. The conventional chemical treatment also showed some improvement in UPF value (23.88) but the ultra violet protection property increased slightly (13.89) after commercial softener treatment. The differently treated fabric samples were washed 20 times and changes in physical and functional properties after 5, 10, 15 and 20 washing cycles were recorded. The enzymatic treatment was found to be most durable as it was successfully retained up to 15 washes. Preferences of experts‟ for development of products from enzymatically softened jute fabric was taken. Top two preferred products from three categories i.e. home furnishing articles, utility articles and apparel & accessories were selected for product development. Eighteen designs (3 for each selected article) were developed using Corel Draw 12 software. On the basis of experts‟ preference, top preferred design for each product was selected for product development. A total of six products viz. table runner, table mats (set of six), wall pocket, handbag, ladies jacket and cap were developed. Their cost was calculated including the cost of fabric, enzymatic treatment, stitching and finishing. The products were got assessed by fifty consumers for their market potential. All the developed products were highly acceptable by consumers. Thus, the enzymatic softening treatment is considered appropriate for jute fabric and it will help in mainstreaming and revival of its status in global market.

    Effect of extract of guava leaves on cotton for microbial resistance
    (CCSHAU, 2016) Jamal, Zeba; Vivek Singh
    Consumers have become more aware of hygiene and potentially harmful effects of microbes, which in turn have increased the demand of antimicrobial textiles. Considering the significance of antimicrobial textiles, the Guava leaves extract treatment was prepared and applied on cotton fabric. To find out the efficiency of Guava leaves extract treatment the parameters like antibacterial activity, wash durability and physical properties of controlled, treated and washed samples were compared. Extraction of Guava leaves was conducted by cold aqueous maceration for two different time periods. 24 hours showed yield percentage of 15 % which was greater than yield percentage obtained by 12 hours i.e. 6%. The concentrations 1mg/ml, 3mg/ml and 5mg/ml were tried for antibacterial activity against Bacillus spp. The 5mg/ml concentration exhibited strong zone of inhibition of 19 mm. The Guava leaves extract was applied on cotton woven fabric by exhaust method in 5g/l concentration. The antibacterial treatment with 5g/l concentration of Guava leaves extract with dilution factor (107 and 108) was cent percent effective after 24 hours of inoculation of Bacillus spp. After 24 hours percent bacterial reduction gradually decreased and on 28th day it reduced to 67%. The Guava leaves extract treated samples exhibited cent percent wash durability after 24 hours of inoculation in washed samples (one wash). After 24 hours it gradually decreased and on 28th day it reduced to 64%. Thus, there was continuous decrease in the antibacterial activity with an increase in incubation period after washing but even then the antibacterial treatment was actively retained in washed samples even on 28th day. After desizing and scouring fabric weight, thickness, bulk and fabric count both in warp and weft direction of fabric increased significantly while tensile strength in both warp and weft directions and air permeability decreased significantly. The percent changes in bending length in both warp and weft directions, flexural rigidity and moisture regain were found to be non-significant. After Guava leaves extract treatment fabric weight and bulk of fabric increased significantly while tensile strength in warp and weft directions, flexural rigidity and air permeability decreased significantly. The changes in thickness, bending length, fabric count in both warp and weft direction and moisture regain were found to be non- significant. After washing weight, bulk, flexural rigidity and tensile strength in warp and weft directions of Guava leaves extract treated samples decreased significantly while air permeability increased significantly. The changes in thickness, bending length, fabric count in both warp and weft direction and moisture regain were found to be non-significant. Conclusively, the Guava leaves extract treated fabrics exhibited excellent efficacy against antibacterial activity and washing. However, it is needed to be renewed after every wash for good resistivity to washing.
