Title: Development of Technical Textiles from Jute and Coir Fibres


1
Development of Technical Textiles from Jute and
Coir Fibres
  • Dr.-Ing. P K Banerjee
  • Professor, Indian Institute of Technology, Delhi

2
Cultivation of Jute in India
  • 66 of world production
  • 3 million tons on 1 million hectare land( 1
    hectare 104 sq. m)
  • Additional benefits
  • Jute stick used as fuel by farmers during rainy
    season
  • 1.5 kg CO2 absorbed from atmosphere per each kg
    of fibre produced

3
Cultivation of Coir in India
  • Each coconut tree produces 75 nuts/year over 74
    productive years
  • 80 tons of fibre from 1 million coconut husks
  • World prod. 55,000 million nuts 4.4 million
    tons of fibre only 0.5 million tons used
    industrially
  • India produces 12,000 million nuts and 0.38
    million tons of fibre 0.58 million tons
    (60) of fibre wasted annually

Motivation for development
  • Serious challenge to sacking from
    lighter,stronger more uniform synthetic
    material
  • New products can be developed for unused coir
    fibres
  • Jute and coir fibres traditionally in household
    and technical textiles
  • Technical textiles expected to grow in Asia by
    4.23 annually during 2000-2010

6
Strategy for development
  • The products should have global appeal
  • The production process should be simple and
    non-polluting. This would keep the cost of the
    product low and be in tune with the overall
    appeal of the product
  • Both fibres are products of nature and should be
    highly compatible for end uses related to soil,
    water and plants
  •

Critical Properties of Jute Coir
  • Both Jute and Coir Lignocellulosic
  • Jute 12, Coir 40 Lignin

Conclusion
  • Limited laboratory scale trials of BRECODRAIN,
    COIRSORB , PsECB and JAO have yielded
    encouraging results
  • production process of all these products is
    fairly simple and non-polluting.
  • Fine-tuning through up scaling and field trials
    is required for commercialization.
