Liquid transport and wicking in nonwoven materials

Описание:
Nonwoven materials are widely used in medical and hygiene applications, and may demonstrate significant anisotropic characteristics in liquid transport. This study investigates the anisotropic liquid transport in such materials, and establishes a relationship between the structure and anisotropic properties of liquid transport. A comprehensive literature review of liquid transport fibrous materials with particular reference to its importance in the function of wound dressings was conducted. A novel computer-integrated instrument is described that measures the in-plane liquid transmission in up to eight different directions. Needle-punched and hydroentangled fabrics with different structural parameters (fibre type, fibre diameter, fabric porosity and fibre orientation) were produced and characterised. The anisotropic liquid transport properties of these fabrics were tested using the new instrument. Unique theoretical models were established to predict the specific directional...Похожие книги
