    Abstract: A jet for treating a yarn with a fluid has a flow control plate having a first and a second flow control opening. The flow control openings are located in the plate such that when the plate is mounted between the jet body and the manifold body, at least one, but preferably both, of the flow control openings in the plate at least partially overlap the inlet end of one (or both) of the fluid supply channels, thereby to modify the fluid flow area presented to the manifold by the fluid supply channel(s).

    Abstract: A process and apparatus for simultaneously drawing and interlacing partially oriented thermoplastic yarns. The process is carried out in a single apparatus by maintaining the yarn under drawing tension and simultaneously contacting the tensioned yarn with a gaseous fluid at an angle, temperature and pressure such that the yarn is simultaneously drawn and interlaced at the point it is being drawn.

    Abstract: An apparatus for treating yarn with fluid designed to provide a yarn, which consists of a multifilament, with coherence by using a working fluid. The apparatus is provided with first and second components which have flat surfaces fixed in parallel against each other with a gap G (mm) provided between them, the first component having at least two fluid conduits which are provided with a specified crossing angle (.theta.) so that they cross each other on the extended lines of their axes and which are opened in the flat surface. The first and second components are fixed to satisfy the requirement in which the gap G between the flat surfaces facing each other is 0.2 mm or more but 5 mm or less, and they eject the working fluid under a specified pressure through at least the two fluid conduits onto the yarn, which runs between the flat surfaces, to provide the yarn with coherence.

    Abstract: A yarn entangling device having a housing with an air pressure cushion in it for urging a piston normally outwardly of the housing. The piston has an air passage through it. Shifting the piston outwardly blocks the air passage. A blast nozzle is secured to the piston for being supplied with air through the piston. A baffle plate opposed to the blast nozzle defines a yarn channel. A holder supports the baffle plate for movement away from and into contact with the blast nozzle. With the holder moving the baffle plate toward the blast nozzle, the piston is shifted to open the air passage to the piston, and with the yarn channel opened with the baffle plate away from the blast nozzle, the piston is moved out of the housing by the air pressure cushion cutting off the air flow to the blast nozzle. A closing flap acts through a detent to secure the holder and baffle plate to close the yarn channel.

    Abstract: A method of manufacturing a composite yarn and composite yarn produced thereby in which a spandex yarn is fed to an air entangling or covering jet while being pre-elongated. Simultaneously, a multifilament partially oriented thermoplastic yarn is fed to the yarn entangling or covering jet while being partially or completely drawn to orient further or completely the thermoplastic yarn. The thermoplastic and spandex yarns are fed through the yarn jet while the filaments of the thermoplastic yarn are entangled to produce a composite yarn with the spandex yarn as the core and the thermoplastic yarn as a covering therefor. The composite yarn is then fed through a false twister and false twisted with the false twist being heat set in the thermoplastic yarn at a temperature which does not adversely affect the spandex core to produce an air entangled false twist texturized composite yarn. If not completely oriented when false twisted, the thermoplastic yarn is further drawn to complete its orientation while being false twisted.
