How does cross-spunlace technology accurately control the air permeability and moisture permeability of medical excipients?

Cross-spunlace line is an advanced non-woven fabric production process that uses high-pressure water flow to spray the fiber web in multiple directions, so that the fibers are entangled with each other to form a non-woven fabric with certain strength and softness. This technology can not only achieve fine interweaving of fibers, but also accurately control the structure and performance of non-woven fabrics by adjusting parameters such as injection pressure, fiber type and interweaving angle.

In the production of medical excipients, the advantages of cross-spunlace technology are particularly obvious. By accurately controlling the interweaving density and strength of the fibers, this technology can produce medical dressings that fit the wound tightly and have good air permeability and moisture permeability. While keeping the wound clean and dry, this dressing can also promote the circulation of air and the balance of humidity around the wound, creating favorable conditions for wound healing and recovery.

Cross-spunlace technology achieves the perfect combination of air permeability and moisture permeability of medical excipients by accurately controlling the interweaving density and strength of the fibers. In this process, the control of interweaving density is particularly critical. If the interweaving density is too high, the air permeability of the material will decrease, affecting the air circulation around the wound; if the interweaving density is too low, the material strength may be insufficient, unable to fit the wound tightly, and affecting the protective effect of the wound.

In order to achieve the best interweaving density control, the cross-spunlace technology adopts advanced control systems and precision injection devices. During the processing, the control system will accurately adjust the injection pressure and injection angle of the high-pressure water flow according to the preset parameters to ensure that the interweaving between the fibers reaches the best state. By real-time monitoring and adjusting the interweaving density, this technology can also ensure that each batch of medical excipients has stable performance and quality.

In addition to interweaving density, fiber strength is also an important factor affecting the performance of medical excipients. In cross-spunlace technology, the strength of the fiber can be precisely controlled by selecting different types of fibers and adjusting the interweaving angle. For example, the addition of high-strength fibers can significantly improve the tensile strength and wear resistance of medical dressings, while appropriately reducing the interweaving angle can improve the softness and fit of the material.

By precisely controlling the interweaving density and strength of the fibers, the cross-spunlace technology achieves a perfect combination of air permeability and moisture permeability of medical excipients. This property enables the medical dressing to fit the wound tightly while maintaining air circulation and humidity balance around the wound.

In terms of air permeability, the medical dressing produced by the cross-spunlace technology has a microporous structure that allows air to flow freely on the surface of the dressing and around the wound, helping to reduce the moisture and stuffiness around the wound and reduce the risk of infection. The microporous structure can also promote the respiration of the wound and accelerate the healing process of the wound.

In terms of moisture permeability, the cross-spunlace technology achieves effective absorption and diffusion of moisture by adjusting the interwoven structure of the fibers and adding special hygroscopic materials. When the wound produces exudate, the medical dressing can quickly absorb the moisture and diffuse it to the surface of the dressing through the microporous structure to keep the wound dry and clean. This moisture permeability not only helps to reduce the pain and discomfort of the wound, but also promotes the healing and recovery of the wound.

The application of cross-spunlace technology in the field of medical excipients not only achieves a perfect combination of air permeability and moisture permeability, but also significantly improves the performance of medical dressings. Specifically, it is manifested in the following aspects:
Improve wound protection effect: By precisely controlling the interweaving density and strength of the fibers, the medical dressings produced by the cross-spunlace technology can fit the wound tightly, effectively prevent the invasion of bacteria and other microorganisms, and reduce the risk of infection. The microporous structure can also promote the respiration of the wound and accelerate the healing process of the wound.
Enhance comfort and patient acceptance: The medical dressings produced by the cross-spunlace technology have good softness and fit, which can reduce the discomfort and pain of patients during use. The perfect combination of air permeability and moisture permeability allows the dressing to keep the wound dry and clean while reducing the moisture and stuffiness around the wound, thereby improving the comfort of the patient.
Reducing nursing costs: Because the medical dressings produced by the cross-spunlace technology have good air permeability and moisture permeability, they can reduce the exudate and infection risk of the wound, thereby reducing the cost of nursing. In addition, the production efficiency and product quality of this technology are also high, which can further reduce the operating costs of medical institutions.
Promote environmental protection and sustainable development: The cross-spunlace technology uses a rich variety of fiber raw materials, including natural fibers, recycled fibers and synthetic fibers. By selecting environmentally friendly fiber raw materials and recycling technology, this technology can reduce energy consumption and waste emissions in the production process, and promote environmental protection and sustainable development.
