A process for simultaneously texturizing a plurality of yarns including feeding a plurality of yarns separately through the inlet of a texturizing device to a cylindrical chamber, supplying a hot compressed fluid to the cylindrical chamber to advance the yarns therein, the hot compressed fluid escaping into an outer closed chamber, and maintaining the outer chamber at a pressure less than the feed pressure of the hot compressed fluid and greater than atmospheric pressure. A texturizing device for use in the above described process including a yarn supplying conduit and an intake member combined to form a suction nozzle supplying a plurality of yarns to be texturized to a cylindrical chamber defined by a tubular member with a wall surrounding the tubular member forming a closed chamber maintained at a pressure less than the feed pressure of a hot, compressed fluid supplied to the intake member and greater than atmospheric pressure, the yarn supplying conduit having tubular channels therein to maintain the yarns separate during introduction into the cylindrical chamber. A textile product formed of an elongated pack of at least two texturized yarns having a substantially smooth, uniform, continuous, peripheral surface.
A textile product formed of a plurality of texturized, continuous filament, polyamide yarns each having a titre of less than 200 dtex, which are configured into a cylindrical pack having a substantially smooth, continuous peripheral surface, said cylindrical pack having sufficient cohesion to resist rupture until stressed by a weight in excess of a predetermined weight, said predetermined weight being at least the weight of one meter of the pack when the pack has a specific weight greater than 0.3 grams per cubic centimeter and wherein said yarns composing said pack separate into parallel strands, when said pack is stressed with a force in excess of said predetermined weight but less than a force required to break the yarns.
