Abstract
The invention relates to a treatment apparatus and process for increasing the air permeability of a textile web, and the airbag fabrics made by such process. The process includes passing the textile web across a first guide having a first guide surface directing the textile web to the treatment body, rotating a treatment body about a treatment body axis, and moving the textile web from the first guide surface in tension around a portion of the treatment body and in contact with the exterior surface of the treatment body, in a direction substantially perpendicular to the treatment body axis, wherein the exterior surface of the treatment body includes at least one longitudinal edge substantially parallel to the treatment body axis, passing the textile web across a second guide having a second guide surface directing the textile web from the treatment body, wherein the included angle between a first plane running from the first guide surface to the treatment body axis and a second plane running between the second guide surface and the treatment body axis is greater than zero degrees and less than about 160 degrees. The treatment apparatus to increase the air permeability is also disclosed.
