Effect of air conditioning systems in weaving?

In the textile industry, AC has a positive effect on both the yarns used in the textile machine, and the machine itself. It reduces humidity levels so the yarns don't absorb the very moisture out of the air as the yarns are dry. Yarns may also absorb the oils from the skin making the workers hands very dry. As for temperature, the machine will run more efficiently in cooler temps as heat will cause the moving parts to expand and friction will result. Too much expansion of certain parts will throw these parts "off" causing imperfections in the fabric.
