Abstract

A method of manufacturing a non-woven web includes the step of collecting stretched filaments that form the non-woven web on a fabric in an apparatus for the formation of non-woven webs. The fabric comprises machine direction (MD) yarns and cross-machine direction (CMD) yarns, wherein the MD and CMD yarns are interwoven in a repeating pattern in which at least some of the CMD yarns are interwoven with the MD yarns in pairs that follow the same weaving sequence. Such a fabric can provide potential advantages such as reduced air leakage, reduced air disturbances, and improved web hold-down effect.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 61 / 387,139, filed September 28, 2010, the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0003] Nonwoven spunbond webs formed from filaments or fibers are typically made from thermoplastic resins in devices such as those disclosed in US Patent No. 5,814,349, the disclosure of which is incorporated herein by reference. Such apparatus typically includes a spinneret for creating the strand curtain, and a process air blower for blowing process air onto the strand curtain for cooling the strand curtain to form thermoplastic filaments. The thermoplastic filaments are then typically carried aerodynamically by the process wind for aerodynamic stretching of the thermoplastic filaments which, after passing through a diffuser, are then deposited on a continuously circulating screen belt or for intertwining long The filaments are b...
