How does hot and humid climate favour spinning and weaving
Answers
it is very favourable to the environment.....
it reduce the demand of the products
All textiles are hygroscopic. That is, they absorb or release moisture depending on the relative humidity of the surrounding air. If the atmosphere is drier than the textile’s equilibrium relative humidity then the textile will give up its moisture to the air. If the air is very humid then the textile’s moisture content will increase. This moisture loss and gain occurs at every stage from the initial processing of the fibres through to final garment manufacturing, distribution and use by the consumer.
This change in moisture content has a direct impact on the properties of textiles, such as tensile strength, elasticity, fibre diameter and friction. A drop in the equilibrium relative humidity of a textile may cause it to be weaker, thinner, less elastic and therefore more brittle. It will also have more imperfections. By maintaining the air humidity whilst processing the fibres, this loss in moisture to the atmosphere is minimised.
There is a suitable range of relative humidity,RH, that is considered ideal for cotton spinning. Above this range rollar lapping and other problems cause lowering of spinning efficiency. On the contrary lowering RH below this optimal range would also increase spinning breaks: due to decrease in fibre cohesion, decrease in pliability, etc. Similarly there is an optimum RH for getting good weaving efficiency also.
1)Cotton textile industry is one of the oldest industries in the world. The warm, moist climate, is favourable for the expansion of this industry
2) This industry flourished in the states of Maharashtra and Gujarat as they had this type of climatic conditions which favoured setting up of cotton spinning and weaving mills in these areas
3) Humid climate has flat terrain which is suitable for setting up of these mills.
4) Ahmedabad in Gujarat is situated closely to cotton growing areas as it ensures easy availability of raw material.
Dry climate usually breaks thread and deteriorates the quality of the cloth while hot humid does not break the thread .This, hot and humid climate favour spinning and weaving.
