In the production process of Spunlace Nonwoven Fabric, the parameters of high-pressure water columns play a vital role. They have a profound impact on the entanglement of fibers and the properties of the final fabric. In order to deeply understand this process, we need to explore the relationship between high-pressure water column parameters, fiber entanglement and fabric properties from multiple dimensions.
First of all, the pressure of high-pressure water column is the core factor affecting the fiber entanglement effect. When the pressure is appropriate, the impact of the water flow is enough to make the fibers tightly entangled with each other when impacted, forming a uniform fiber network. This entanglement not only increases the overall strength of the fabric, but also enhances its durability. However, if the pressure is too high, the fibers may become excessively damaged or even break, which will have a negative impact on the performance of the fabric. Therefore, precise control of the pressure of the high-pressure water column is crucial.
Secondly, the jet distance of the water column is also a key factor affecting the fiber entanglement effect. Shortening the hydroentanglement distance means that the water flow can impact the fiber web at a shorter distance, thereby increasing the impact force on the fiber. This helps improve the entanglement of the fiber web, making it tighter and more even. However, if the spray distance is too short, the water flow may not fully penetrate the fiber web, resulting in uneven entanglement or local loosening. Therefore, a reasonable setting of the spray distance is key to ensuring uniform fiber entanglement.
In addition, the diameter of the water needle also has a significant impact on the fiber entanglement effect. A smaller water needle diameter can make the water flow more concentrated, thereby increasing the impact. This concentrated impact can more effectively promote the entanglement between fibers and make the fiber web more stable. However, it should be noted that a water needle diameter that is too small may limit the flow of water, thereby affecting production efficiency. Therefore, when selecting the diameter of the water needle, it is necessary to comprehensively consider the relationship between the entanglement effect and production efficiency.
In order to further improve the performance of spunlace non-woven fabrics, manufacturers also need to carefully adjust other parameters of the high-pressure water column, such as water flow speed, spray angle, etc. By optimizing these parameters, the fibers can be entangled more evenly and tightly, thereby improving the strength, moisture absorption and breathability of the fabric. At the same time, manufacturers should also pay attention to the selection of raw materials and pre-treatment processes to ensure the best quality and performance of the fibers.
To sum up, the parameters of high-pressure water column play a vital role in the production process of spunlace nonwoven fabrics. By precisely controlling parameters such as pressure, jet distance and water needle diameter, fiber entanglement and fabric performance can be optimized. At the same time, manufacturers should continue to explore new processes and technologies to improve the quality and competitiveness of spunlace nonwovens. With the continuous advancement of science and technology and the continuous development of the market, it is believed that the performance and application fields of spunlace non-woven fabrics will be further expanded and improved.
