Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeability. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%. The film provides a low permeability airbag cushion exhibiting a leak-down time of at least 5 seconds wherein the film is present on the surface in an amount of at most 3.0 ounces per square yard of the fabric.

The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds. All coatings, in particular elastomeric, non-silicon coatings, and coated airbags, meeting these criteria are intended to reside within the scope of this invention.

A method and an apparatus serve to process a catch selvage that has been trimmed from a web being woven on a loom, so as to separate weft thread ends and leno threads from the catch selvage to produce a type-pure weft thread waste and a type-pure leno thread waste or reusable leno threads. The term "type-pure" refers to a waste material containing a single uncontaminated type or color of thread material, e.g. wool vs. synthetic or blue vs. red. After the catch selvage (1) has been trimmed from the edge (11) of the woven web (2), the leno threads (4, 4') are untwisted from each other by being rotated by an untwisting apparatus (5) in a direction opposite the binding twist applied by the leno device (18). Thereby, the full leno binding (1A) is completely unbound and opened, so as to release the weft thread ends (3A), which are then sucked into a proper one of weft waste collection containers (6B) by a suction pipe (6A), so that only a single type-pure and / or color of weft thread end is collected in each container (6B). The unbound leno threads (4) are collected as a type-pure waste or are rewound on spools to be reused. Alternatively, by using endless closed-loop leno threads (4'), the leno threads (4') are continuously recirculated back to the leno device (18), without intermediately being wound onto spools.
