lifekeepup.com Abstract : Medical dressing products were prepared by the company All Clean Natural spunlaced technology with the same viscose parameter fiber and polyester fiber as raw materials to quantitatively analyze the water vapor permeability of the conventional nonwoven fabric used as the functional layer of dressing. Various water pressure and different angles were used to test the pore structure of dressings. Based on the dressing application environment, the water vapor permeability of nonwoven dressing with different compositions was discussed . The results show that hydrophilic-hydrophobic properties are present in the pore structure and provide a significant effect on water vapor permeability. The water vapor permeability of nonwoven fabric composed of viscose ranges from 9 300 to 11 000 g / (m :。 24 h) , While the one of nonwoven fabric made of polyester ranges from 8 800 to 9 700 g ...
lifekeepup.com Spunlace is also known as hydroentanglement or hydro-jet. The jet spraying method uses high-speed and high-pressure water to impact the fiber web. This principle was developed by Dupont and Chicopee back in the late 1950s and early 1960s. It was a relatively new nonwoven processing technology in the 20th century. Fiber, the product does not use adhesives, does not lint, does not shed, the product is hygroscopic, soft, high strength, and feels good. Hydroentanglement Process Like the process principle of needle-punched, spunlace nonwoven fabrics use high-pressure water flow to form a "water needle," acting like acupuncture. The web is fed into a r...
