Abstract

A three ply sandwich structured hydroentangled web is disclosed. The top and bottom plies of this web comprise long synthetic fibers having a fiber length of about 30 to 100 mm and the middle ply comprises cellulosic fibers having a fiber length of about 1 to 8 mm. The middle layer cellulosic fiber can optimally be wholly or partially replaced with short synthetic or other natural fibers having a fiber length of about 6 to 27 mm.These hydroentangled webs are useful in the manufacture of towels, wet wipes, industrial wipes and medical gowns.
