CIRCOT Miniature Spinning System (MPD)

Description and salient technical features : CIRCOT Miniature Spinning System has been developed for assessment of spinning quality of small cotton fibre samples and for the preparation of fibre sliver and yarn samples. The system consists of four table model microprocessor controlled machines (units):

  • CIRCOT Miniature Carding Machine
  • CIRCOT Miniature Draw frame
  • CIRCOT Miniature Sliver to Yarn Spinner
  • CIRCOT Rotor OE Spinner

In each of the machines, inverter drive systems have been employed for easy settings of various processing parameters. Roller and other moving components are supported with ball/needle bearings for smooth and friction free operation. Movement of fibres during processing has been so controlled to enable faster processing of samples and for the production of quality yarn. Pneumatic suction systems have been incorporated in the ring frame, rotor spinner and carding machine and in lickerin zone for collection of broken ends/droppings. Optimised tray for guiding of lap and sliver during feeding to the draw frame and tongue-and-groove type chrome plated calendar rollers with provision for changing the trumpet bore size have been used in the draw frame.



A Brief Timeline (MPD)

  • 1924 : First spinning test conducted in Asia
  • 1927 : Study of Blowroom treatment on Indian cottons – results have been used extensively for development of modern blowroom line
  • 1928-1931 : Specimens of fabric over an ancient relic recovered from the archaeological Excavations at Mohenjo-Daro – Investigated and the fibres identified as ‘cotton’
  • 1925-1933 : Full Spinning technique developed and standardised
  • 1927 : Research on Spinning Environment (65% R.H. & 27ºC Temp. optimum for spinning process)
  • 1929 : Project on evaluation of representative trade varieties of Indian cottons started
  • 1932 : First training course on cotton technology for persons deputed by industry conducted
  • 1933 : The First Edition of the Handbook on ‘Methods of tests on fibre, yarn and cloth’ published
  • 1935 : Research on cotton combing – the process causes reduction in neps and significant improvement in spinnability by increase in mean fibre length
  • 1936 : R & D on using curved path during drafting, enabling better control over floating fibres resulting in yarn of higher strength. This basic concept with suitable modifications has been used extensively in the spinning industry 
  • 1938 : A thumb rule for cotton mixing established
  • 1949 : Causes of neps in Indian cotton yarns
  • 1950-1962 : Development of the unique ‘Micro spinning technique’, where a small quantity (as low as 42 g) of lint obtained from an individual plant could be subjected to actual spinning test. This enabled the breeders to obtain comparative spinning values of quite a large number of new strains in a short period of time and at an earlier stage of propagation
  • 1956-1957 : Reports on the experiments carried out on Amber Charkha, at the laboratory, Effects of storage of baled Indian cottons at Bombay and at their respective growth centers on the lint quality, A review of the studies of the relationship between the spinning value and the chief fibre properties of a cotton
  • 1958 : Degradation of cotton during mechanical processing
  • 1962 : Studies on the relationship between fibre properties and spinning value of cottons of Staple 1-1/16” and above
  • 1967 : It became one of the major hub of activity of the All India Coordinated Research Project on Cotton (AICCIP) initiated by ICAR leading to a greater coordination between fibre technologists and breeders
  • 1974 : Research trials on blending of the then newly developed Indian cotton varieties such as Sujata, Suvin, PSH, Varalaxmi and Hybrid-4 with polyester fibre for producing medium to fine count yarn, comparable to blends obtained from imported Giza-45 and Sudan cotton   
  • 1976 : ICAR award for team research and the Indian Merchants’ chamber award for outstanding contribution in the field of agriculture
  • 1979 : Advent of Rotor Spinning technology in India, setting up of research facility at MPD
  • 1980-2005 : Relentless work in evaluating spinning potential of new strains of cotton developed by breeders from all over the country. Dedicated work was done to maintain the quality, and attempts to improve the potential of existing varieties of cotton through AICCIP, Standard and Trade variety sample processing and testing. Over 22,000 new and improved strains have been tested for the fibre properties, spinning performance, or both, and over 5,000 technical reports have been issued to the cotton breeders, which have contributed to place the breeding work for quality cottons on a sure and scientific foundation.
  • 1980-1985 : Studies on: Efficiency of high draft on short spinning sequence, Blending of cotton with similar and dissimilar fibres, Development of: Cotton-Jute fibre and Cotton-Pineapple fibre blended products
  • 1985-1989 : Extensive Rotor spinning trials: Fine spinning, Mixing, Spinning of Man-made Fibres and blends, Development of Cotton/Viscose Hollow Polyester Fibre Blended Light Weight Suiting Fabrics
  • 1989-1993 : Studies on Causes and Control of Yarn Faults – Results were well received by the industry, helped it to attain 5% Uster Norms
  • 1993-1995 : First Air-jet spinning of Indian cottons and their Blends with Polyester
  • 1995-1997 : Cotton Knitting Studies
  • 1996-2000 : Research on-
    • Design Modification and Optimization of Pneumatic Splicer for Production of Better Quality Splice Joints
    • Spinning and Fabric Manufacturing Trials from Naturally Coloured Cottons
  • 2000-2005 : Upgradation of the existing machinery to be in line with industry standards
    2007 : Setting up of Friction Spinning (DREF-3) facility and beginning of research on technical yarns/textiles
    2007-2012 : Research on two prestigious NAIP funded sub-projects-
    • Design & Development of Flexi-Check Dam (Rubber Dam) for watershed management
    • A Value Chain projects for Coconut fibre and its by-products  
  • 2009-2012 : Setting up of Modern Blowroom, Carding and Drawframe facility, Core Spinning and Compact spinning facilities
  • 2013-2014 : Setting up of Electrospinning facility and Compression Moulding Machine
