AI Technical Summary
In the existing process of polypropylene fiber preparation, steam cooling causes temperature fluctuations in the yarn, affecting its physical properties and potentially generating harmful byproducts that pollute the environment and endanger health.
A combination device consisting of a heating tank, a drawing device, and a cooling tank is used. The heat from the heating tank is transferred to the coolant via a drive shaft. Combined with coolant circulation and fan blade airflow, the temperature reduction process of the fiber is controlled, ensuring that the fiber gradually solidifies without losing its plasticity.
It achieves uniform cooling and curing of fibers, improves production efficiency and fiber quality, avoids environmental pollution and health risks, and ensures the stability of fiber physical properties.
