The Art of Water Pressure: The Core Control in Wet-laid Hydroentanglement Machine

In the complex process of wet-laid hydroentanglement machine, water pressure undoubtedly plays a vital role. This seemingly simple physical parameter actually contains a profound impact on the degree of fiber entanglement, fabric quality and even the entire production process.

As the primary consideration of hydroentanglement processing, water pressure directly determines the impact of high-pressure water flow on the fiber mixture. This invisible force, like a skilled craftsman, accurately controls the entanglement process between fibers. Appropriate water pressure can make the fibers fully intertwined and tightly entangled, forming a porous structure that is both strong and breathable; on the contrary, too high pressure may be like a sharp knife, cutting and damaging the fibers, resulting in reduced fabric strength and rough feel; while too low pressure is like a weak touch, which cannot effectively promote the entanglement between fibers, making the fabric loose and weak, and difficult to meet the use requirements.

Facing the double-edged sword of water pressure, wet-laid hydroentanglement machine operators must have a high degree of professionalism and keen insight. They need to carefully set and adjust the water flow pressure according to the type and characteristics of the fiber and the final use of the fabric. For fragile fibers, such as some natural fibers or fine-denier chemical fibers, lower water flow pressure is required to reduce damage; for fibers with higher strength and stronger entanglement, the water flow pressure can be appropriately increased. In addition, the thickness, density, and performance indicators of the fabric such as air permeability and strength are also important factors to consider when adjusting the water flow pressure.

With the advancement of science and technology and the development of intelligent technology, wet hydroentanglement machines have also ushered in new breakthroughs in the regulation of water flow pressure. Modern wet hydroentanglement machines are generally equipped with advanced computer control systems and sensor technology, which can monitor and record the changes of various parameters in the production process in real time, including water flow pressure, thorn tip length, thorn density, etc. Through data analysis and algorithm optimization, the system can automatically adjust the water flow pressure to the optimal state to achieve accurate and efficient production control. This intelligent control method not only greatly improves the stability and consistency of product quality, but also reduces the errors and uncertainties caused by human factors.

Thanks to the continuous development and improvement of the precise control technology of water flow pressure, nonwovens produced by wet spunlace machines have shown great application potential and market prospects in various fields. In the medical field, high-quality nonwovens are widely used in the production of medical supplies such as surgical gowns, masks, and bandages; in the field of environmental protection, they are used to make environmentally friendly products such as filter materials and oil-absorbing materials; and in the fields of home, automobile, agriculture, etc., wet spunlace nonwovens are also favored for their unique performance and wide range of applications.

As the core control factor in wet-laid spunlace machines, the importance of water flow pressure is self-evident. By precisely controlling the water flow pressure, we can not only ensure that the quality and performance of nonwovens are in the best state, but also promote the continuous progress and development of wet spunlace machine technology.
