Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-12) Arya, Mamta; Goel, Alka
    The growing ecological consciousness demands for better waste management practices. Thus in the present study an attempt was made to extract sericin, a waste from silk industry .It the present study that sericin was successfully extracted from the degummed liquor of oak tussar silk cocoon. Sericin yield percent was 8.3 at optimum liquor ethanol ratio i.e. 3:1 and incubation time 6 hours. Further FTIR, molecular weight, nitrogen percent, protein content, solubility and amino acid profiling was done and it was found that extracted sericin has amide I, amide II and amide III peaks which confirmed the presence of C=O (1500-1600cm-1) and N-H groups (1400 cm-1). Molecular weight of oak tussar sericin ranged from 15kda to 250kda and nitrogen percent was 2.5%. Various amino acids were found namely Serine, Aspargine, Proline, Threonine, Cystine, Glycine, Alanine, Methionine, Phenylalanine, Tryptophan, Glutamic acid and Aspartic acid whereas serine percentage was highest (22%) among all the amino acids. Cotton fabric was finished with extracted oak tussar sericin. Box-Behnken Design of Response Surface Methodology was used for optimization of finishing variables. After the analysis of linear, interactive and quadratic model terms the optimized recipe for finishing was consisted of 51gpl sericin concentration, 2% citric acid, 60˚C temperature, 60 minutes time and 1:20 M L Ratio. Finished fabric was then tested for physical, comfort and functional properties. It was found that durability of finish was good. Breaking strength of finished fabric was 21 kgs in warp direction and 17.8 kg in weft direction. Elongation of finished fabric was 23% in warp and 23.8 % in weft direction. Thickness (from 0.23mm to0.25mm), fabric weight (from 98 g/m2 to 101 g/m2) and bending length (from 1.4 cm to 1.6 cm) of finished fabric were increased. Crease recovery angle of finished fabric was increased significantly from 78˚ to 102˚ in warp and 84˚ to 112˚ in weft direction which inferred that creasing of finished fabric was decreased. Thermal resistance of fabric was improved as clo value of finished fabric (0.21clo) was more than the control fabric (0.04). Air permeability and wicking of finished fabric was decreased whereas water absorption of finished fabric was improved. Finished fabric exhibited improved antimicrobial property with different concentration (35gpl, 50gpl and 65gpl) of sericin. Highest zone of inhibition i.e. 6mm against E.coli and 7mm against S. aureus was observed with the highest concentration of sericin. Better UPF property was also observed in the finished fabric as UPF value was increased from 8.6 to 15.8. Further dyeing of finished fabric was done with synthetic direct dye and Butea monosperma natural dye. In case of direct dyes it was found that when dyeing was done on the sericin finish, fabric colour strength was slightly decreased whereas colour strength was increased when dyeing was done in the fabric finished with sericin and dyed with Butea monosperma. Overall fastness of both the dyes was improved with the finish application. The cost of sericin finished fabric was found Rs 650 per meter. The extracted sericin can be potentially used as biopolymer in textile dyeing industry. The developed finished fabric can be utilized in apparel sector and in medical textiles as bed linen, surgical gowns, uniforms, wipes etc.

    Existing profile of textile printing units of Pilkhuwa and development of screen printed furnishing articles inspired from Chikankari motifs
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Upadhayay, Hema; Goel, Alka
    The role and importance of small-scale industries are very significant towards employment generation. Dyeing and printing of fabrics have always been a part of the small scale industry. Pilkhuwa, a small town in Hapur (U.P) is also carrying its legacy of printed textiles since long back which is famous for furnishing items, especially bed sheets. In the present research work analysis of current status, changing scenario, ecological aspects and its marketing profile of dyeing & printing units of Pilkhuwa was done. It was found from survey results that small scale handloom industry of Pilkhuwa is need to be reviewed in terms of printing recipe, product range and existing design to fit in current pursuits of consumer preference and trends. The physiochemical analysis of effluent samples collected from dyeing and printing units revealed that the pH of washing effluent is slightly acidic (3.80) whereas effluent sample generated from indigo sol dye and scouring & bleaching found alkaline pH i.e. 9.7 & 10.41 respectively. BOD and COD were found higher whereas TDS and nitrate were found within permissible limit. All the heavy metals were in permissible limit except Cu which was found beyond permissible limit both in the effluent as well as in the printed fabric of aniline black dye. Results of the Eco testing of different printed samples, revealed that all the tested parameters were found within the permissible limits as per Oeko-Tex except for the amount of Pb which is slight high and Cu was found very high from the prescribed permissible limits specially in aniline printed sample. Owing to the results of ecological and physiochemical testing printing recipe for aniline black was optimized by using BBD (Box and Bachken) model. Optimization was done by minimizing the CuSO4 concentration and using FeSO4 as a substitute. It was found that using CuSO4 in the lower concentration a reduction of 79.33% and 83.95 % of Cu was observed in effluent and fabric respectively whereas 81.62% reduction of lead was observed in the printed fabric. Using FeSO4 as a substitute resulted in 82.53% reduction in lead content whereas the amount of Fe reported in the fabric and effluent was 144 mg/kg and 0.58 mg/kg respectively. To widen the existing product range and to impart novel look to the existing prints of Pilkhuwa fine Chikankari embroidered prints were tried to infuse through screen printing. A range of chikankari inspired screen printed home furnishing articles (curtains, dining, sofa cover set and diwan set) were developed under the research work. The developed articles were evaluated by the panel of experts and marketing personnel. As per views of experts and market personnel the developed printed articles were found suitable and believed to provide product diversification in the existing market. 55% experts and 60% of the marketing personnale opinioned that the developed articles were appropriate in cost, whereas 32.77% experts and 17.77% of the marketing personnale opinioned that the developed articles are low in cost and deserve better marketing cost. Around 60% of the experts and market personnale were willing to give a profit percentage up to 50% for the developed printed articles, whereas for few articles specially diwan sets, a very few market personnel and experts were ready to give profit share up to 80-100%. This need based study will help in enhancing the range of designing and productivity along with providing a safe alternative for printing recipe in terms of lower metal loads and hence may boost road map for development of quality products.

    Optimization of dyeing conditions for wool and silk fabrics using dyes extracted from Rumex nepalensis and Girardinia diversifolia roots
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-04) Bhandari, Babita; Anita Rani
    Colouring the textiles with dyes has been an ancient craft known to mankind around the world. Present day environmental conditions compel human beings to remain covered with textiles processed through green technology for protection against effects of climate change. Hence natural dyes’ use in textile colouration sector has increased. Exploiting natural sources of dyes may create undesirable burden on environment. So in this study, weed plants had been explored for their dyeability. Weeds grow faster and absorb nutrients more efficiently and thus limiting their availability to crop plants. In this study, two sources i.e. Rumex nepalensis and Girardinia diversifolia which are abundantly available as weeds in hilly regions of Uttarakhand were used for dyeing of silk and wool fabrics. Optimization of dyeing conditions and effect of mordants on colour strength and fastness properties were assessed. Box-Behnken Design of Response Surface Methodology was used for optimization of dyeing variables for application of both dyes on silk and wool fabrics. The optimized dyeing variables obtained for application of R. nepalensis on silk fabric were 1.12% w/v dye concentration, 90ºC dyeing temperature and 81.599 minutes dyeing time whereas in case of wool optimized dyeing variables were 0.992 % w/v dye concentration, 90ºC dyeing temperature and 76.515 minutes dyeing time. In case of G. diversifolia,2.91% w/v dye, 90ºC dyeing temperature and 90 minutes dyeing time was found optimum for dyeing of silk fabric and dye concentration of 2.62 % w/v, dyeing temperature of 90ºC and dyeing time of 30 minutes were found to be optimum for dyeing of wool fabric. Mordanting method and concentrations of selected natural (amla, pomegranate peel and harad) as well as synthetic mordants (alum, copper sulphate and ferrous sulphate) were optimized on the basis of colour strength and wash fastness. The colourfastness properties of dyed silk and wool fabric samples improved after mordanting with both types of mordants in case of two dyes used in the study. Application of both dyes and mordants on silk and wool fabrics improved the UPF and antimicrobial properties when compared with their control samples. Tensile strength and elongation of mordanted dyed fabrics was significantly affected from undyed fabrics but not from dyed fabrics. Residues of few heavy metals were found on the dyed fabrics but those were present within permissible limit. Since no chemicals are used at any stage of dyeing, this study can be useful for small scale dyers who have no access to effluent treatment facility and generated wastewater can be safely discharged into the environment.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-03) Lakhchaura, Pallavi; Gahlot, Manisha
    The present study was planned to see the possibility of blending of oak tasar silk waste and acrylic blended fibres to prepare yarns and woven fabrics. Blending and spinning of fibres were done on cotton spinning system. Five blend ratios (100:0, 60:40, 50:50, 40:60 and 0:100 Oak tasar waste: Acrylic) were prepared at NITRA, Ghaziabad on ring spinning. Their physical properties and imperfection were evaluated. Ten fabric samples were woven from developed yarns on handloom out of which four were blended fabrics with plain weave and four with twill weave. Two were union fabrics each with plain and twill weave in which 100 % acrylic yarn was used as warp and 100 % oak tasar silk yarn was used as weft. The physical (cover factor, cloth cover, fabric weight, fabric thickness, crease recovery angle, bending length, flexural rigidity, drape coefficient, abrasion resistance, pilling, tensile strength, elongation at break and dimension change) and comfort (thermal insulation value, clo, Q-max, air permeability, water vapour transport rate, water absorption, vertical wicking and horizontal wicking) properties were assessed and statistically analyzed using post hoc tukey test and paired t- test. The tenacity values of oak tasar silk and acrylic fibre were comparable. Acrylic fibres were finer as compared to oak tasar fibres. Elongation percent of acrylic fibre was higher as compared to oak tasar fibre. Yarn count of the developed yarns was ranged from medium to fine i.e. 22 Ne to 28 Ne. The physical properties, unevenness and imperfection of blended yarn were improved with the addition of acrylic fibres with oak tasar silk in the blend. Light weight plain weave and twill weave fabrics of oak tasar silk and acrylic blended yarns were developed among them the twill weave fabrics had higher cloth cover, fabric weight and thickness as compared to plain weave fabrics. Most of the physical properties of fabrics were improved with the addition of acrylic fibre in the blend for both plain and twill weaves. Comfort properties like Q-max, air permeability, water vapour permeability, thermal insulation and clo value were found to be increased with increasing acrylic content in the fabric. Most of the comfort properties of different blended and union fabrics were more or less close to each other for both plain and twill weaves. These fabrics may be used for light winter wear clothing and apparels as they were light in weight with clo value comparable to sweater.

    Under present research status of textile artifacts and prevailing conservation practices in the selected Indian textile museums were documented, finish suitable for conservation of textiles was developed and designs of showcases for impressive display of textiles in museums were created. Twenty eight Indian textile museums were selected for survey. The details of artifacts collection and conservation practices followed by the museums to protect the textile antiquities from deterioration were noted. Survey results revealed that edible sources such as black pepper and clove were used to conserve the textiles in the museums. So, an economical antimicrobial finish extracted from plant source was developed, it will also help in saving edible sources. To develop the antimicrobial finish efficacy of the methanolic extracts of seven plants were tested against Gram Positive, Gram Negative and fungus by Agar Well Diffusion Method for bacteria and Food Poison Method for fungus. Methanolic extract of Khinna (Falconeria insignis) was selected for casement fabric application on the basis of maximum zone of inhibition exhibited against the test microbes. Conditions for applying the plant extract on the fabric were optimized on the basis of the bacterial resistance efficacy of the variables tested by Box-Behnken Design software. Both bacteria and fungus showed highest bacterial and fungal resistance for nine percent of plant extract whereas, four percent concentration of citric acid resulted in lowest bacterial zone of inhibition was observed at 30 minutes of treatment time. The treated fabrics were dried and were tested for physical properties. It was concluded that methanolic extract of Falconeria insignis leaves are safe and economical to provide antimicrobial protection on casement fabric, which may be used as base fabric for placement of artifacts in the museums. Designing of display boards for effective showcasing of the product as well as their conservation process to safeguard the textiles. In order to design display showcases the artefacts displayed in the museums were categorized in twelve categories Total sixty designs of showcases were prepared using Photoshop software along with their dimensions, recommended material for construction of particular showcase and estimated cost was also calculated. The prepared designs of showcases were got evaluated by the conservators and curators of five museums surveyed.

    Fatehpur Sikri, Agra is one of the famous place in India, where monuments were built by Mughals. It was capital of Emperor Akbar from 1571 to 1585 AD. Many monuments are located in Fatehpur Sikri and Jama Masjid is one of them. Jama Masjid was constructed with redstone. Decorative designs were carved on redstone and wooden structure of Jama Masjid. These decorative designs can be used for textile designing. Therefore, present study was undertaken to document these designs and to adapt the designs to used on kurtis through screen printing. Under the present study the decorative designs were collected from different sections of Jama Masjid and were documented. Documented designs were categorized into broad border, narrow border, buti, central designs and neckline designs. Seven designs were selected from each category thus making the total of 35 designs for adaptation using CorelDRAW X7. The adapted designs were assessed by a panel of 30 judges. Out of thirty five designs, fifteen designs were selected on the basis of highest weighted mean score. Garment selected for printing of designs was kurti as it is a trendy Indian upper garment which never goes out of fashion. Then, twenty line design patterns were prepared on the basis of arrangement of different categories of motifs/designs on kurtis. Five line design patterns were selected based on highest weighted mean scores. Forty two design arrangements were prepared using selected adapted designs based on selected line design patterns, out of which five design arrangements were selected based on assessment made by 30 judges. Complementary colour scheme was used for colouring of selected design arrangements on kurtis. Cream colour cotton fabric was printed using selected design arrangements with the help of screen printing technique. The printed kurtis were assessed. The kurtis were assessed on different parameters namely appropriateness of motifs/designs according to the product, placement of motifs/designs arrangement on kurtis, suitability of colours used for printing with the background colour of fabric, quality of printing, size of motifs/designs used and overall appearance. All the kurtis were highly appreciated by the consumers which is evident from high ratings obtained in weighted mean score.

    The strong sense of individuality that consumers possess today when coupled with the concept of globalization has led to the popularization of the concept of brands in India which was not well established a few decades back. The availability of more number of brands has resulted in consumers having a wide variety to choose from. A number of factors along with the demographics of the consumers and the previous interactions with any brand form the basis for their preference towards it. The present study was planned to find out the existing trends in the wardrobes, purchasing practice and attitude among students of technical institutes located in metro and non-metro areas towards branded apparels and accessories. A questionnaire-cum-interview schedule was formulated to obtain information regarding the existing wardrobe, purchasing practice and attitudes of respondents towards branded apparels and accessories. The survey method was used to collect information from male and female students pursuing undergraduate and postgraduate courses of engineering from College of Technology, G.B. Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar, Uttarakhand and Delhi Technological University, Shahbad Daulatpur, Main Bawana Road, Delhi. Stratified random sampling method was used for selection of respondents. The total sample size was of 480. The collected data was statistically analyzed using frequency, percentage, WMS, t-test and chi-square test. Stark difference was observed in the existing wardrobes of the respondents. The respondents studying in the institutes located in metro area possessed more numbers of branded apparels and accessories. It was also found that the respondents of the metro based institute were aware of more number of brands for apparels and accessories. The purchasing practices indicated that the amount of money spent by the respondents studying in the institute situated in metro area on branded apparels and accessories was more than that of the respondents of non-metro based institute. The respondents of metro based institute also preferred to shop for these branded articles from retail shops rather than online modes to ensure the genuineness of the brand and were found to be less price sensitive.

    Value addition of dhaincha (Sesbania aculeata) fibres through dyeing with synthetic and natural dyes
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Arya, Mamta; Anita Rani
    The growing ecological consciousness and limited land availability for cultivation of fibre yielding crops have pressed researchers to explore under-utilized and new natural resources that could offer textile fibres for numerous end uses both technical and aesthetic. The hills of Himalayas and Tarai region of Kumaon are endowed with indigenous flora rich in natural fibres due to favourable climatic conditions. Some of these plants are bhimal, bhindi, bhang, rambans, bichu grass, shahtoot, timla, banana and oak used by the local masses for fibre extraction and its usage for manufacturing household items. One such unconventional plant source of textile fibre is dhaincha. Dhaincha is a green manure crop used prior to paddy cultivation and is also one of the valuable medicinal herbs. Botanically, this plant is known as Sesbania aculeata and by common names as danchi, dhaincha, dunchi, danicha. This plant belongs to leguminacea family. This harsh, coarse and shiny fibre has potential to find use in the different sectors. The present study was, therefore, planned to explore the use of dhaincha fibre in home textiles. Value addition of dhaincha fibres were done through dyeing with five synthetic dyes namely reactive, sulphur, vat, direct, and azoic and five natural dyes namely, Rubia cardifolia, Acacia catechu, Punica granatum, Indigofera tinctoria, and Curcuma longa. Optimization of M: L ratio and dyeing time was done prior to application of dyes on the fibres. Further the effect of dyes on physical properties of dhaincha fibre was assessed. Also the fastness of dyed dhaincha fibre was tested against washing, rubbing and light. Finally non woven fabric was prepared by needle punching method for product development It was found that the fibres could be dyed easily with natural and synthetic dyes. The dyed fibres exhibited high to medium colour strength. The fastness ranged from fair to very good against washing; very good to excellent against rubbing and poor to good against light. The dyeing of fibres affected the physical properties too. The moisture regain of the fibres improved effectively on dyeing with both the types of dyes. Non woven fabric was prepared by needle punching loom and fabric was utilized to make hand fan, magazine holder and table mat to showcase the possible use of dhaincha non woven for home textiles and travel utilities in vehicles.
