Abstract: A technique for combining at least two unlike yarn ends to produce a composite yarn. One of the two unlike yarn ends is a spun yarn and the other of the two unlike yarn ends is a continuous multifilament yarn. The technique includes removing each of the two yarn ends from respective supply packages under predetermined tensions. The yarn ends are separated to maintain a predetermined included angle between the yarn ends. The separated yarn ends are then fed through an entangling jet to combine the yarn ends and collected on a take-up package. In the preferred embodiment, the included angle between the yarn ends varies between 3 and 17 degrees. The resulting air entangled yarn has an average number of 80 tacks per yard and an average loop size of 174 inch or less.

Abstract: A system to texturize partially oriented yarn in which the yarn is wrapped around a logarithmic spiral shaped hot draw pin to draw the yarn before the texturing thereof. The shape of the hot draw pin provides even distribution of normal force on the surface of the draw pin.

Abstract: The invention involves a method to texturize absorbable or absorbable/nonabsorbable components that are to be used to fabricate textile grafts of all sizes, and specifically for repair of the peripheral vascular system and for coronary bypass use. The bioabsorbable component of the graft fosters increased tissue ingrowth into the graft as compared to conventional 100% nonabsorbable grafts. Increased tissue ingrowth leads to greater patency through formation of a vascularized neointima and less tendency to be aneurysmal through formation of a suitable adventitia. The absorbable component can be a variety of materials, including PGA, the polymer used to manufacture the MAXON.TM. suture, etc., whereas the nonabsorbable component (to be used as the backbone) can be new materials, e.g. the polymer used to manufacture the NOVAFIL.RTM. suture, or more conventional polymers, including polyester, polyamide or polypropylene.

Abstract: For continuously crimping thermoplastic filaments, a filament bundle is blown by a jet nozzle into a stuffing chamber of a texturing wheel to produce a crimped filament bundle in the stuffing chamber. The stuffing chamber has a receiving zone, a treatment zone and a delivery zone. The filament bundle is subjected to a texturing or crimping treatment in the receiving zone and, depending upon the fiber material to be processed, undergoes a heating or cooling treatment in the treatment zone. The heating or cooling treatment is accomplished by a blowing agent which blows a gaseous medium into the stuffing chamber. At the delivery zone, the crimped filament bundle is taken-off or lifted-out of the stuffing chamber by fiber bundle-lifting means and moved towards a suction drum receiving the filament bundle.
