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.

    Tie and dyeing of cotton with reactive dye
    (CCSHAU, 2012) Singal, Jyoti; Saroj S. Jeet Singh
    The present study was conducted to standardize dyeing process of reactive dye for cotton using tie and dye technique. Red hot reactive dye was selected for dyeing of white cotton fabric. Standardization of dyeing variables viz, dye concentration, dyeing temperature, dyeing time, dyeing pH and different auxiliaries concentrations were optimized on the basis of percent dye absorption and visual appearance. Colour fastness properties of tie-dyed samples were also evaluated regarding washing, sunlight, perspiration and rubbing fastness. It is summarized that 4 percent was the optimum dye concentration on the basis of maximum percent dye absorption whereas on the basis of colour fastness 2 percent was optimized. Thus 2 and 4 percent were selected as light and medium shades of red reactive dye. The optimum dyeing temperature was 80°C, time was 90 minutes and pH was 10.5 for both the dye concentrations. 60g/l of sodium sulphate concentration was selected for 2% dye concentration and 70g/l for 4% dye concentration as it gave maximum dye absorption. 15 g/l concentration of sodium carbonate was selected for 2% dye concentration and 20g/l for 4% dye concentration as it gave maximum dye absorption Samples were tied and dyed with the standardized dyeing conditions and dyed samples were assessed for their colour fastness properties. Samples with 2 percent dye concentration gave better colour fastness properties than 4 percent dye concentration. Shopping bags were developed by object binding, knotting and leharia technique using reactive dye were highly appreciated by the experts as well as consumers. Training on use of hot reactive dyes for tie and dye technique using standardized dyeing conditions was imparted to rural women. Training was found to be very effective as there was significant gain in knowledge.

    Application of reactive dye for batik on cotton
    (CCSHAU, 2012) Shweta Rani; Saroj. S. Jeet Singh
    The study was conducted to standardize dyeing process of reactive dye for batik on cotton. Batik printing is traditional Javanese printing. It is a kind of resist printing and the resist used in this basically is a wax resist. Proportions of resist i.e. paraffin wax, bees wax and resin optimized for standardization of batik resists mix. Effect of ageing on resist mix was also assessed on the basis of resist parameters and percent dye absorption. Cold reactive dye was selected for dyeing white cotton fabric. Standardization of dyeing variables viz, dye concentration, wetting agent concentration, dyeing temperature, dyeing time, initial pH, dyeing pH and different auxiliaries concentration were optimized on the basis of percent dye absorption and visual appearance. Colour fastness properties of batik printed samples were also evaluated regarding washing, sunlight, rubbing and perspiration fastness. Batik printed fabrics were used to develop shopping bags. Training was imparted to interested rural women on use of reactive dyes for batik on cotton. It is summarized that 50:50:5 ratio for batik resist mix was optimized using paraffin wax, bees wax and resin. Two days duration for wax storage was optimized. The optimum dyeing temperature and dyeing time with cold reactive M brand dye was 30°C and 90 minutes respectively using dyeing concentration 6%, initial pH 7.0, dyeing pH 11.0, wetting agent (urea) concentration 60g/l, sodium sulphate concentration 60 g/l and sodium carbonate 10g/l. Fastness grades for batik dyed fabric for both colour change and colour staining was good to excellent. Shopping bags made by batik using three wax application techniques and dyed with reactive dye were highly appreciated by consumers on all the parameters. Training on use of reactive dye for batik and techniques of wax application was imparted to rural women and was found to be very effective as there was significant gain in knowledge on various aspects of use of reactive dye for batik at 5% percent level of significance.
