  • Patent number: 9309608
    Abstract: A method and a device for producing a crimped multifilament thread are described. A multiplicity of filaments are extruded by means of a spinning machine, cooled and subsequently treated by a drawing device and a crimping device to form a crimped thread. Before the thread is wound up to form a bobbin, a multiplicity of intertwining knots is produced on the crimped thread by a treatment device. In order to obtain defined patterns of the intertwining knots within the thread, a pulse sequence of compressed air pulses at a predefined frequency is directed at the thread. The treatment device has a controllable blowing means.

    Abstract: Techniques produce intertwining knots in a multifilament thread. In such techniques, an air stream pulse is generated by a nozzle channel opening into a treatment channel periodically with an interval between successive air stream pulses. During an interval, the air stream pulse is directed transversely onto the thread guided in the treatment channel so that a continuous sequence of intertwining knots is produced in the running thread. An auxiliary air stream is generated continuously or discontinuously and the auxiliary air stream and the air stream pulse are blown in together into the treatment channel.

  • Patent number: 7568266
    Abstract: The invention relates to an entanglement nozzle and to a method for producing fine knotted yarn with highly regular knots by means of air jets comprising a yarn treatment channel. According to said method, air is blown transversally to the yarn treatment channel. Said blown air forms a respective double swirl both in the yarn transport direction and against the yarn transport direction for creating the knots. According to the invention, upon entry into the yarn treatment channel, the blown air is converted into two intense, stationary eddy currents that are not disrupted by filament bundles, in an air swirling chamber that only extends for a short distance in the longitudinal direction of the yarn channel. The regularity of the knots can be significantly improved, despite the tiny dimensions of the air swirling chamber, which projects beyond the longitudinal wall of the yarn channel for a maximum 0.5 mm or for 5% to 22% of the width (B) of said channel.

    Abstract: The invention relates to a method and an apparatus for strengthening a running non-woven web. For this purpose, the non-woven web is penetrated by a plurality of fluid streams. In order to create a surface structure, the fluid streams are generated by a movable nozzle beam, which is guided back and forth at a defined amplitude substantially transversely to the running direction of the non-woven web. In order to obtain enough flexibility and a sufficient volume in the non-woven web in spite of the strengthening effect, the amplitude for moving the fluid streams back and forth is selected in such a way according to the invention that the points of impact created in the non-woven web by adjacent fluid streams do not intersect an imaginary separating line in the running direction. To this avail, the amplitude of the back and forth movement of the nozzle beam is adjusted so as to be smaller than half the distance between two nozzle outlets disposed next to each other in the row.

  • Patent number: 6880212
    Abstract: A continuous method for producing composite elastic yarns at speeds up to 700 m/min by (a) stretching (drafting) an elastomeric yarn (e.g., spandex) by 2.0× (100%) to 10.5× (950%) while heating (max. heating temperature 220° C.) in a single or double stage draft, (b) air-jet entangling with a relatively inelastic yarn component to create a composite elastic yarn, and then (c) in-line heat-treating (max. heating temperature 240° C.) the composite elastic yarn. The initial draft stage(s) may also be carried out at ambient temperature. The resulting composite elastic yarn has improved stitch clarity, particularly suited for hosiery, and its properties can be tailored to provide fabric properties for knit and woven fabrics hitherto not possible with standard spandex yarns.

  • Patent number: 6868593
    Abstract: An apparatus and method for improving multifilament textile yarn interlacing includes two spaced apart interlacing jet nozzles 2a and 2b positioned so that the yarn channels 4a and 4b of the two nozzles are aligned in a tandem relationship. High pressure air is injected into an upstream nozzle 2a with a velocity component tending to entrain or advance the yarn through the upstream nozzle 2a. High pressure air is injected into the downstream nozzle 2b with a velocity component tending to retard passage of the yarn through the downstream nozzle 2b.

  • Patent number: 6834417
    Abstract: A method of treating filament yarn includes supplying a plurality of yarn filaments through a yarn channel of a nozzle in a yarn travel direction and introducing a blowing medium into the yarn channel substantially in a direction of the yarn travel direction and at an angle of introduction of more than about 15° and less than about 45° from a direction perpendicular to the yarn travel direction. The plurality of yarn filaments are mixed within the yarn channel so as to produce a filament yarn substantially free of knits.

  • Patent number: 6826814
    Abstract: A texturizer is a base which provides a plurality of inlets directed to stations internal to the base. Each of the stations communicate internal to housings which have inserts therein. Receivers in the inserts receive air from the stations and direct the air towards distal ends of the housings through slots. Prior to reaching the distal ends of the inserts, passages through the inserts direct air to an internal bore in the insert and proximally out the insert bore. The insert bore extends all the way through the insert and through the housing so that yarn is pulled through the housing and crimped preferably at an impingement point in the insert.

  • Patent number: 6709623
    Abstract: Improvements to processes and equipment for the manufacture of nonwoven webs useful in numerous applications including personal care, protective apparel, and industrial products. The fiber and/or filaments used to form the nonwoven fabric are deposited on a forming surface in a controlled orientation using application of an electrostatic charge to the fibers and/or filaments in combination with directing them to an electrode deflector plate while under the influence of the charge. The plate may be made up of teeth with a separation and angle orientation that are selected in accordance with the desired arrangement of the fibers and/or filaments in the nonwoven web. As a result, properties of the web such as relative strengths in the machine direction and cross-machine direction can be controlled.

  • Publication number: 20040016092
    Abstract: In a texturing system with a texturing nozzle and a first drum (22) connected thereto and a further drum (23), a thread is guided on the outlet side of a texturing nozzle (10) at the circumference of a drum (22) in the form of a strip (1′) by friction and at least in part in positive manner, so that the longitudinal speed of the strip (1) at the circumference of the drum (22) accords with the circumferential speed of the drum in the area of the guide (220), whereby, by means of a pressure difference in an air guidance system, the effect is achieved of pressing the strip (1′) onto the surface of the drum (22), and whereby the thread is guided in relation to its conveying speed and packing density, by positive and friction guidance under the imposition of air, as far as an outlet point on the first drum, and is transferred onto a second drum (23), on which the strip is cooled, extended if appropriate, and passed on to further guide or conveying rollers (22′) respectively.
