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.
