The Development of Hydroentanglement (Spunlace) Nonwoven Fabric

Image
  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...

Analysis of Water Vapor Permeability in Spunlace Nonwoven Fabric

Image
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 ...

  1.1 Before tampons and sanitary pads are invented In Ancient Greece in the 10 th century before feminine napkin and tampons were invented.  Women use sheep’s wool, cotton, rag, rabbit fur, knitted pad to hold up their monthly cycle; Ancient Japanese women use paper cuttings from origami as menstrual pad; Hawaiians felt comfort to use local fern; African women use grass and in Indonesia, menstruating women ply vegetable fibers as a menstrual pad. 1.2 Development of tampon The discovery of cotton made out of wood pulp during the 18 th century was purposely for men not for women, when nurses in France used cotton as bandages to stop blood from war victims.  It is cheaper and easy to dispose of. Manufacturers then started the first commercial use of disposable pads called the Southball pad.  In the US the idea was developed by Johnson and Johnson which they called Lister’s Towel: Sanitary Towel’s for Ladies. 1.3 When were tampons invented? Who invented tamp...
