Promote yarn strength, reduce static and fly, and achieve high machine speeds

Ensuring the correct level of relative humidity in textile production areas has a beneficial effect on fibre moisture content and tensile strength. This helps to reduce yarn breakage, minimize lint and fly, and facilitates efficient yarn production. Further processes such as knitting and weaving can also be achieved at higher machine speeds and with less defects. The optimum relative humidity level for a particular process depends mainly upon the nature of the yarn or fibre, but is typically 55%rh to 65%rh. Natural fibres such as cotton or wool have a higher regain and are best processed at higher levels of relative humidity, whereas, for man made fibres such as nylon and polyester, recommended levels are lower. The elimination of static is an important benefit of humidification, particularly with these man-made fibres.
