Tobacco Twines Specifications
Manufactured from 100% cotton. Available in 250g, 500g, 1kg and 2kg spools, either polished or unpolished. Tobacco twine is mainly used for tying and hanging tobacco leaves for curing and bale stitching.
Effects of moisture
Moisture swells the fibre and has the effect of increasing the strength of the cotton twine, however prolonged exposure to moisture increases the chances of microbial attack on the fibre which leads to a decrease in strength.
Polished cotton twine will reduce absorption of moisture.
Chemical Resistance
- Cotton is attacked by hot dilute or cold concentrated acid solutions.
- Acid hydrolysis of cellulose produce hydro-celluloses.
- Cold weak acids do not affect the cotton.
- The fibres show excellent resistance to alkalis.
Degradation
Cotton is degraded mainly by the hydrolysis effect of acids.
Effect of temperature
In a dry state, cotton can be heated up to 150 degrees Celsius without decomposing but when the heating is prolonged, a brown colour develops, signaling the onset of decomposition.
