中文简体In the production process of non-woven fabrics, the spunlace process is undoubtedly the most critical link. It uses high-pressure water flow to spray the fiber web, and through the action of physical force, the fibers form a tight and stable connection, thus giving the non-woven fabric excellent physical properties and wide application potential. The high-speed random parallel spunlace production line is the specific implementer of this process.
Everything starts with the pre-wetting of the fiber web. Before officially entering the spunlace area, the fiber web needs to go through a pre-wetting process. This step seems simple, but it is actually crucial. It aims to make the fibers in the fiber web fit more closely together by adding an appropriate amount of water, while expelling the air between the fibers, laying a solid foundation for the subsequent spunlace reinforcement. The pre-wetted fiber web seems to be wrapped in a thin layer of water film, which not only maintains the softness of the fiber, but also increases the friction between the fibers, providing favorable conditions for the displacement and entanglement of the fibers.
When the pre-wetted fiber web slowly enters the spunlace area, a carefully choreographed "fiber dance" is staged. The numerous water jet holes on the water jet plate of the water jet head are like precise miniature fountains, spraying multiple high-pressure fine water jets. These water jets are shot at the fiber web at a nearly vertical angle, with such a fast speed and high pressure that they can change the movement trajectory of the fibers in an instant.
Under the direct impact of the water jet, some fibers on the surface of the fiber web begin to displace. Some fibers are pushed by the strong water flow, as if being pulled by an invisible force, and move vertically to the back of the fiber web. This vertical movement not only deepens the degree of interweaving between fibers, but also creates more possibilities for subsequent fiber entanglement. The other part of the fibers, under the action of the rebounding water flow, shows a more complex displacement path. Driven by the water flow, they sometimes roll and sometimes interweave, forming a series of staggered fiber interweaving networks.
The displacement of fibers is not just a simple linear motion, but also includes the interweaving and interlacing between fibers. In this process, countless tiny, flexible entanglement points are formed between the fibers. These entanglement points are like "locks" in the fiber network, firmly connecting the originally loose fibers together to form a tightly connected and well-arranged three-dimensional fiber network.
It is worth noting that these entanglement points are not mechanically stacked together, but through physical friction and mutual engagement between fibers, a flexible and stable connection is formed. This connection method not only gives the non-woven fabric good tensile strength and tear strength, but also maintains its excellent breathability and softness. In addition, since no chemical adhesives are used in the whole process, the non-woven fabric produced is more environmentally friendly and safe, which meets the requirements of modern industry for sustainable development.
The reason why the high-speed random parallel spunlace production line can occupy a place in the non-woven fabric manufacturing industry is inseparable from its unique technical advantages. The production line adopts an advanced automatic control system, which can realize precise spunlace parameter adjustment and fiber displacement control, so as to ensure that each production can achieve the expected fiber entanglement effect. By optimizing the layout and spray angle of the water spray holes, the production line can achieve full coverage and uniform spraying of the fiber web surface, further improving the uniformity and stability of the fiber network. High-speed random parallel spunlace production line also has the advantages of high production efficiency, low energy consumption, good environmental protection, etc., which meets the modern industry's pursuit of high efficiency, energy saving and environmental protection.
With excellent physical properties and wide application potential, non-woven fabrics produced by high-speed random parallel spunlace production line have shown great application value in many fields. In the field of medical and health care, non-woven fabrics are widely used in the production of surgical gowns, masks, sanitary napkins and other products; in the field of filter materials, non-woven fabrics are used as the base material of filter materials such as air filtration and liquid filtration due to their good air permeability and filtration performance; in the field of wiping products, non-woven fabrics have become the preferred material for industrial wipes, kitchen paper, car wipes and other products with their soft feel, good moisture absorption and wear resistance. Non-woven fabrics are also widely used in packaging materials, thermal insulation materials, electric heaters, clothing linings and other fields, providing strong support for the development of modern industry.
