The control of water pressure needs to be precise and meticulous. Higher water pressure can enhance the entanglement effect between fibers and improve the strength of non-woven fabrics, but too high water pressure may lead to excessive fiber damage and affect product quality. Therefore, it is necessary to set appropriate water pressure according to different product requirements and fiber characteristics. This usually needs to be determined through a lot of experiments and experience accumulation, and it is constantly adjusted and optimized in actual production.

The regulation of water quantity is also crucial. Too little water may not fully realize the spunlace effect, so that the fibers are not tightly entangled and the properties of non-woven fabrics are affected; Too much water may cause waste of water resources and increase the burden of subsequent drying and other links. The water quantity can be controlled by adjusting the parameters such as the size and number of water spray holes and the flow rate of water.

When regulating water pressure and water quantity, it is also necessary to consider the performance and running state of the equipment. Advanced spunlace equipment often has more accurate pressure and flow control devices, which can better meet the regulation requirements. At the same time, comprehensive consideration and dynamic adjustment should be made in combination with the actual production situation, such as production speed, fiber types and other factors.

In addition, it is necessary to establish a perfect monitoring system. Monitor the changes of water pressure and water quantity in real time, so as to find problems and make adjustments in time. Through continuous exploration and practice, the most suitable combination of water pressure and water quantity parameters is found, so as to achieve the best effect of nonwoven spunlace process and produce high-quality nonwoven products.
