The roving is introduced to the texturizing machine (air jet), which breaks the surface fibers at random under the effect of compressed air. That gives the roving a bulkier appearance. Then, the texturized roving wound into a bobbin.
PU foam sheets, fiberglass or fiberglass chopped strand mats and non-woven polyester fabrics are bound by a binder and laminated to form automotive headliners.
