A yarn having good entanglement and good quality, preferably a multifilament polyamide yarn, a method for making the yarn, and a woven fabric made from the yarn wherein the yarn comprises the following properties: the yarn length per defect is greater than or equal to about 3000 meters per defect; the maximum skip length is less than or equal to about 120 millimeters; the ratio between yarn length per defect to maximum skip length is greater than or equal to about 50; the entanglements per meter times the average entanglement strength is greater than or equal to about 120; and the yarn can be woven sizeless. The yarn of the invention is useful in the sizeless weaving of fabric used in air bags.

Method of making sizeless yarn

An entangled multifilament yarn, preferably an entangled multifilament polyamide yarn, and a knit fabric made from the same, wherein the yarn has an entanglement strength of at least about 4.5, an entanglement strength coefficient of variance of less than about 1.10, and an average entanglement length for each entanglement of at least about 11.0 mm. The yarn has a knitting performance of at least 4,000 racks/defect.

Entangled polyamide yarn

Enhanced knitting performance for fine denier polyamide apparel yarn is obtaining by applying to the yarn a finish composition comprising
