摘要:
A knitted web and a method for making the same includes a plurality of wipers, each having a wiper body with a length defined between finished leading and trailing edges and a width defined between opposed, selvaged side edges. The wipers are knitted with continuous yarns, including a primary yarn and a reinforcing yarn, and a separable portion is knitted between individual wipers using a dissociable yarn. Loose primary and reinforcing yarns extending between wipers are cut and the dissociable yarn is removed from between the wipers to separate the web into individual wipers with edges that require no edge treatment to prevent raveling.
