CIRCOT Research Achievements 2012-2013

The following are some of the achievements made by the Institute in various research programmes for the year 2012-2013

  • Fully green composites with encouraging tensile properties have been produced using jute as reinforcement and PLA fibre as matrix in the laboratory scale. Besides, Banana fibre used as reinforcement with matrix of thermoplastic polypropylene film was found to produce composite with good tensile modulus making it suitable for applications requiring high rigidity
  • The research on application of Nano technology on cotton fabrics has proved successful in imparting Super Hydrophobicity by surface modification of cotton textiles.
  • A new core SiO2 — shell TiO2 complex nanoparticle of 300-500 nm has been synthesized. The same was used to produce durable UV protection cotton textiles of excellent rating (UPF 50+).
  • Two solid state fermentation processes have been developed using different combinations of microbial strains for detoxification of free gossypol from 0.22 to 0.04 % and total gossypol from 2.3 to 0.8% with simultaneous improvement in the lysine content. This development poses as a viable alternative protein supplement that can replace soybean meal either partly or completely, in poultry feed.
  • CIRCOT has designed and fabricated indigenous atmospheric pressure plasma reactors with and without cooling system with advanced plasma characterization facilities such as mass flow controllers, digital oscilloscope with voltage and current probes, optical emission spectroscopy (OES) and gas chromatography mass spectroscopy (GC-MS) for application in textile processing.
  • A new on-line RFID bale tagging system to track the bales has been developed. The technology can provide online information about the Pressmark No, Year of manufacture, Lot Number, Bale Number, Weight, Quality Parameters like Grade, Variety, Fibre Length, Micronaire, UR%, Trash and Moisture measurement. • The segregation and refining of bulk coconut fibres into grades of fine, coarse and medium fibres have been achieved in bulk trials of 360 kgs, carried out with the CIRCOT developed Coconut Fibre Segregator Machine. Compact and dense non-woven/mat has been prepared from the segregated fine fibres.
  • Successful designing and fabrication of co-axial nozzle attachments have been achieved for electro spinning of Core-sheath Nanofibres into Yarns in laboratory scale.
  • A pedal driven CIRCOT-Phoenix Charkha for spinning coarse long-staple fibres from banana pseudostem at the cottage level has been developed. A multi-sheath feeder attachment to banana fibre Raspador machine has been developed. This feeder was found to increase productivity of fibre extraction by 1.5 to 2 times.
  • A new process for quick composting of wet and dry agro biomass has been achieved by using aerobic microbes and CIRCOT anaerobic consortium, saving 15 and 30 days respectively with better NPK content compared to farm yard manure.
  • Use of pomegranate rind powders (plant extract) as mordant followed by alum treatment produced a very good orange-red hue on scoured and bleached cotton fabrics upon dyeing with natural dye and also significantly improved UV resistance property of textiles with UPF value of 50+.
  • A new process for making nanocellulose compatible with synthetic polymeric matrix like polyethylene and polypropylene using a non-ionic surfactant and/or an anionic surfactant through noncovalent bonding has been developed.
  • A study has indicated that primary sources of fine dust pollution during operation in ginneries are the unclosed/uncovered gin machines, belt conveyors and pre-cleaner. About 90% fine dust are originating from ginning point of double roller (DR) gins.
  • In the flagship project, Cotton-rich blended yarns of 40s count with 4 twist levels in blend ratios of 80:20, 65:35 and 50:50 with PLA fibres were produced by compact ring spinning. Lea CSP in the range of 1800-2100 has been achieved for 80:20 blend ratio.
  • Seven hundred and eighty one containers of indigenous calibration cottons were supplied to the textile industry as reference materials for calibrating their modern testing instruments and generating Rs. 4,03,647 as revenue.
  • Under the scope of All India Coordinated Cotton Improvement project (AICCIP) quality analysis of 3686 samples has been done of which 928 samples belong to zonal trials, while 2758 samples correspond to National Trials. The quality analysis carried out on 25 standard varieties of cotton revealed no significant change in properties in comparison to that observed at the time of release of those varieties.
  • The capacity of the rotary knife roller gin was found to be six times that of the Jumbo double roller gin; the percent cut-seed during rotary ginning of cotton was found lower than that found with double roller gin.
  • Fabrics with bright and dark colours were obtained when dyed with extract of tender coconut husk and use of an inorganic salt as the secondary mordant. Scale-up trials were carried out using rope dyeing machine and Rotary Pressure Vessel.
  • Energy consumption of up-packing type of cotton bale press was found to lower by 40% compared to downpacking press for 15 and 25 bales/hr capacities. Operational cost was also found lower by 10%. Technology and Business Promotion Activities
  • Eighteen consultancies relating to cotton technologies were undertaken by the institute during the reported period.
  • Thirty-one delegates from select African Countries — Benin, Burkina Faso, Chad, Mali, Malawi, Nigeria and Uganda underwent an International Training cum Exposure Programme on Post Harvest Management of Cotton & Value Addition to crop residues (Cotton TAP) under support from Dept. of Commerce, Ministry of Commerce & Industries (Govt. of India).
  • The ZTM & BPD unit, for the first time organized a 3-day Entrepreneurship Development Programme (EDP) with 22 participants for Technologies on Biomass Utilization, Focus: Particle Board &Nanocellulose, generating a revenue of Rs. 1,76,000/-
  • Fourty-two personnel underwent training at Headquarter on quality evaluation of fibres and in using sophisticated instruments like HVI and AFIS including basic statistical interpretation of data; one hundred and fifty personnel including many farmers in fourteen batches underwent training on the operation and maintenance of various ginning machines apart from training on quality evaluation of cotton; thirty-six cotton farmers from Junagadh, Gujarat participated in a training under the ATMA scheme at GTC, Nagpur. More than 9500 cotton samples received from trade, industry, research and educational institutes were evaluated for quality under the paid test category at CIRCOT headquarter and at regional quality evaluation units. Seven MoUs were signed with different clients relating to technologies and services on cotton technology. Nine patents on new technologies and machines developed by the institute were filed with the patent office. The dynamic reconstituted ZTM-BPD unit at CIRCOT generated revenue worth Rs. 25 lakhs.
