The art of reinforcement of viscose and polyester ginkgo dot spunlace nonwovens

In the hall of textile technology, pre-humidification treatment is the essential link in the production process of viscose and polyester ginkgo dot spunlace nonwovens, and its importance is self-evident. This process is not only the initial wetting of the fiber web, but also lays a solid foundation for the subsequent spunlace reinforcement process.

In short, pre-humidification treatment is to introduce an appropriate amount of water into the formed fiber web through a specific method to make it reach a certain wet state. This process seems simple, but it actually contains profound scientific principles. The wet fiber surface has subtle changes in physical properties, making its interaction with the water jet more efficient.

A thin layer of water film is formed on the wet fiber surface. When this layer of water film is impacted by the high-speed water jet ejected by the spunlace machine, it can transfer energy as a medium, so that the impact force of the water jet is more evenly distributed between the fibers. At the same time, the lubricating effect of the water film also reduces the friction resistance between the fibers, making the fibers more likely to displace, intersperse and entangle when subjected to external forces. This physical change at the microscopic level is the key to improving the effect of spunlace reinforcement by pre-humidification.

With the help of pre-humidification, viscose and polyester fibers have shown their own unique advantages.
Viscose fiber: Known for its high hygroscopicity and softness, the pre-humidified viscose web can quickly absorb and retain moisture to form a uniform water film coverage. This not only enhances the overall stability of the web, but also provides a more moist and soft working environment for subsequent spunlace reinforcement. Under the impact of the water jet, the displacement and entanglement between the viscose fibers are tighter, forming a more solid non-woven fabric structure. This structure not only has good air permeability and hygroscopicity, but also has excellent biocompatibility, which is particularly suitable for medical and health fields with high requirements for material performance.
Polyester fiber: Characterized by its high strength, wear resistance and chemical stability, it also shows excellent performance after pre-humidification. Although the hygroscopicity of polyester fiber is relatively weak, pre-humidification can still effectively improve the wet state of its surface, so that it can better interact with the water jet during the spunlace reinforcement process. The high strength of polyester fiber makes the reinforced non-woven fabric have excellent tensile and wear resistance, which is particularly suitable for making products that need to withstand large external forces or frequent use. The ginkgo point design further improves the surface friction and aesthetics of the non-woven fabric, making it have broad application prospects in many fields.

The pre-humidified web shows better performance in the spunlace reinforcement process. The efficient interaction between the wet fiber surface and the water jet promotes the displacement, interlacing and entanglement between fibers, thereby significantly improving the reinforcement effect of the non-woven fabric. This improvement in reinforcement effect not only enhances the mechanical properties and service life of the non-woven fabric, but also provides strong support for its wide application in many fields such as medical, health, home, and clothing.

As a key link in the production of viscose and polyester ginkgo point spunlace non-woven fabrics, the scientificity and importance of pre-humidification treatment cannot be ignored. In the future, with the continuous development and innovation of textile technology, we have reason to believe that this process will be further optimized and improved, injecting new vitality and impetus into the development of the non-woven industry.
