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.
