Abstract
Provided are an elastic composite non-woven fabric and a manufacturing equipment and a manufacturing method thereof, wherein the elastic composite non-woven fabric manufacturing equipment includes an upper feed roller, an upper shrink roller, an upper bonding roller, upper fins, an middle feed roller, an winding roller, a lower feed roller, a lower shrink roller, a lower bonding roller, and lower fins. Wherein, two elastic non-woven fabrics shrink inward by the shrink roller and enter the gaps among the fins and grooves and teeth of the bonding roller to form regular wavy folds; the two pre-shrunk elastic non-woven fabrics are bonded to the upper and lower surfaces of the elastic material in a flat state by the aligned and adjacently disposed teeth of the bonding roller, thereby forming an elastic composite non-woven fabric.
