4. Advantages

The loose stock dyeing machine is designed to be low energy-losing, low lift, and large quantity flowing with mixed-flow pump. The spiral flow-guiding blade direct the waterflow to get a best permeability, to get the lowest energy-consuming and highest efficiency. To reach the effect of colour fastness and evenness, no colour variety and fluffing.

New-model weir floating adjutage, dyeing pipe and yarn-carrying pipe can work together to avoid the twisting and knotting of yarn, thus it can be wound on bobbin easily with few yanr-losing.

The water adjutage with special design can adjust water flowing speed according to the equantity of dyeing yarns, the number of single yarn and its sorts. It has low bathing-ratio, which makes it save material and reduce the cost be way of imporving its structure.
