composed primarily of the plant materials cellulose (major component of plant fibre) and lignin (major components of wood fibre)
Chemical Composition of Jute Fiber
- Cellulose → 65.2%
- Hemi-cellulose → 22.2%
- Lignin → 12.5%
- Water Soluble matter → 1.5%
- Fat and Wax → 0.6%
Defects in Jute
Rooty Jute: in these jute the lower parts of jute fires contain barks.
Specky jute: this defects occur because of insufficient washing which causes the outer barks to adhere in some places
Croppy Jute: this is a defect where the top end of the fibre become rough and hard. It is usually caused by careless steeping.
Knotty jute: the jute fibres contain knots in places and it is caused by insect bite or punctures.
Dezed or Dead fibres: due to over retting in moist condition, the fibre becomes dull, lose strength and becomes inferior for spinning.
Runners: this is a defect where long and hard barky ribbon of fibres remains in jute fibre.
Hunka: defects caused by non-removal of dried up base and hard bark from the fibres.
Mossy jute: fibres from short plants that cannot be properly stripped and cleaned contain broken piece of jute sticks etc.
Flabby or Fluffy jute: due to careless stripping, fibre loses firmness and becomes flabby and hairy
Heart damage: These defects occur when jute fibre contains excess moisture when baled. The centre of the bale becomes badly tendered and in some cases fibres are reduced to powder.
