Effect of Polyester and Viscose Content on the Performance of Spunlaced Nonwoven Dressings

Abstract:

Three kinds of spunlaced nonwoven dressings, which were made in the same process, were chosen with different fiber content. The absorbency rate, water-vapor transmission rate and diffusion area in solution A were measured. The experimental results showed that the viscose content is the key factor in water-vapor transmission rate of Polyester/Viscose spunlaced nonwoven dressings. As the viscose content increased 70% from 30% , the water-vapor transmission rate of the spunlaced nonwoven dressings also increased accordingly. The increase of viscose content is beneficial to spunlace entanglement, and improve the absorption capacity. Conversely, the increase of polyester content goes against the spunlace entanglement, but contributes to the improvement of fluid spreading.
