Elastic recovery analysis of nonwoven fabric with mesh structure

It introduces several mechanical entanglement morphologies between fibers of spunlaced nonwoven under tensile stress.And it argues that the elastic recovery of spunlaced nonwoven is governed by the deformation resilience of the holes produced by high speed jets of water and the elasticity of fiber itself.The mathematical model is used to demonstrate the most common U-shaped tangling way,and fiber-to-fiber meets T1=T0eμθ,if the water jet pressure is identical,the larger the static friction coefficient μ or fiber covering angle θ,the better the tangling of fiber and more stable the fibrous web and therefore the better the elastic recovery of the fibrous web.Finally combined with the actual production,an ideal mesh model was developed to investigate the correlation of mesh size and horizontal or longitudinal extension deformation,and it shows that the elastic recovery of the nonwoven is governed by the fiber arrangement in the fibrous web.
