Analysis of Elastic Recovery Property Based on the Mesh Structure of Spun-Laced Nonwovens

Abstract:

By means of entanglement and consolidation, fibers form stable web in spun-laced nonwovens, it initially conceived fibers entanglement structure and analyzed morphological changes in the stress state, the result showed that the elastic recovery property of spun-laced nonwovens could be adjusted through the deformation resilience of water mesh and the elastic fiber itself. Meanwhile the mathematical model demonstrated the most common "u-shaped" entanglement method between fibers,so fiber I slip from the fiber Π which met the equation T1 = T0×e μ θ. Under the same water jet pressure condition, larger static friction coefficient (μ) or fiber coated Angle (θ) equals better fiber entanglement, more stable structure and better elasticity. Combining the actual production with ideal mesh model, the size relations of horizontal and longitudinal extension deformation about Δ L and Δ L' was discussed. The results showed that the elastic recovery property of nonwovens could be improved through changing fibers arrangement of the fiber web.
