Abstract: A yarn, especially a sewing thread or an embroidery thread, is described, which has the structure of a core yarn with at least one core consisting of multifilament yarns and a spin over of staple fiber yarns. At least one portion of the fibers, which build the staple fiber yarn of the spin over, is bound between the filaments of the at least one multifilament yarn of the core over its total axial fiber length or over a section of its axial fiber length. Furthermore a method to produce this yarn is described.

Abstract: A unique formulation for yarn from a novel combination of fibers of polyester and silver which is made by a special manufacturing process including proprietary individual steps. The formed yarn product is durable and useful and can be used to make various fabrics and/or materials and, most particularly, to make final products that possess highly advanced characteristics, particularly fire retardant properties and antimicrobial properties.

Abstract: A composite bast fiber and cotton yarn is formed by blending natural bast fibers with cotton fibers which have been regenerated from waste cotton material such as trimmings and cuttings from the apparel manufacturing industry. The regenerated cotton and bast fibers are cleaned and blended, then carded to align the fibers into strands. Depending on the size and texture of the desired yarn, the fibers are stretched and drawn into slivers prior to spinning to join the fibers together. The natural bast fibers are up to two and one half to three time longer than the regenerated cotton fibers, so that the natural bast fibers overlap and braid onto the regenerated cotton fibers during spinning. The resultant yarn is stronger and more absorbent than yarns made solely out of regenerated cotton fibers, a blend of regenerated cotton and acrylic fibers, or regenerated cotton and polyester fibers currently available.

Abstract: The invention provides a spun yarn comprising polyester bicomponent staple fiber and acrylic staple fiber. The invention further provides a method for making spun yarns and fabrics. The spun yarn of the invention comprises at least 30 weight percent acrylic staple fiber and from 17 to 45 weight percent polyester bicomponent staple fiber comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate), based on the total weight of the yarn.

Abstract: A spinning machine includes a plurality of spinning stations or places. Each spinning place includes a yarn formation mechanism that is supplied with staple fiber material in the form of a longitudinal object. Each spinning place includes a refining mechanism by way of which the longitudinal object is refined prior to the fiber material being supplied to a yarn formation mechanism. Each refining mechanism is independently drivable and controllable with respect to the other refining mechanisms. At least one sensor is disposed at each of the spinning places to detect at least one measurable property correlated with fiber mass per unit of length. A controlling monitoring unit is configured to receive and process data measured by the sensor. A control monitoring unit is configured with the refining mechanism at the associated spinning place for control of the refining mechanism as a function of the property detected and measured by the sensor independent of the refining mechanisms at other spinning places.

Abstract: The invention provides a spun yarn comprising cotton and a bicomponent polyester staple. The fiber of the invention exhibits unusually high stretch characteristics and has excellent cardability and uniformity.

Abstract: A combing roller for use in a singling-out device of an open-end spinning machine includes a cylindrical body having a plurality of teeth formed on its outer circumference. Each of the teeth is formed by the intersection of at least one spiral circumferential groove with a number of recesses. The recesses are disposed on the circumference of the cylindrical body at an angle of up to 45 degrees relative to the direction of a force generating line which is parallel to a rotational axis of the cylindrical body.

Abstract: A method of and an apparatus for producing a blended yarn from cotton fibers and man-made or synthetic fibers. According to conventional methods the blending of cotton fibers and man-made fibers has been hitherto effected subsequent to a cotton combing process. In order to obtain an appropriate yarn quality, it is necessary to comb out the cotton and thereby separate the short fibers thereof. With the prior art method of bringing together or combining the blend constituents subsequent to the cotton combing process, there have been problems with regard to a homogeneous blending of cotton and man-made fibers. A great number of machines is thereby required and the corresponding constructional expenditure is high. Therefore, a method and an apparatus are suggested and according to which the two blend constituents, namely cotton fibers and man-made fibers, are already brought together or combined prior to the combing process.

Abstract: A fine heterogeneous hybrid spun yarn is blended from electrostatically conductive staple fibers and electrostatically non-conductive staple fibers so that the yarn is electrostatically conductive only over short discrete lengths. When used in pile fabrics, such as carpets, the fine yarn is introduced with at least some of the carpet facing yarns during the carpet making operations. The resultant carpet structure substantially eliminates electrostatic shock to a human walking across the carpet and approaching a ground such as a light switch, radio, or another person. Such a carpet does not constitute a dangerous floor covering.The unique heterogeneous hybrid spun blended yarn is achieved by process techniques completely contrary to accepted blending practices.

Abstract: Textile slivers tend to loose their cohesion when travelling over long distances from one piece of storage or processing equipment to another such piece of equipment. This problem is overcome by subjecting the sliver to a false twisting process during its travel, desirably by a pneumatic false twister located immediately adjacent to the sliver-receiving equipment.

Abstract: The present invention relates to an improved process for blending together textile like fibers exhibiting a relatively high modulus of elasticity together with textile fibers exhibiting a relatively low modulus of elasticity which blend can further be converted into a high quality blended yarn structure. When the textile fibers exhibiting the relatively high modulus of elasticity are also electrically conductive, such as e.g. metal or carbon fibers, then the resulting yarns and fabrics can be designed with a predetermined level of electrical conductivity.

Abstract: A method for producing chemically untreated fire resistant fiber blends includes the steps of separately blowing and carding bundles of selected matrix and staple fibers, respectively, to form separate slivers of each of the two fibers. Given proportions of each fiber are then combined during a common drawing step to form a bulky blended sliver which is then conventionally processed to produce a fire resistant yarn. The yarn is suitable for knitting or weaving to provide fabrics which far exceed current government fire resistant standards.

Abstract: The present invention provides a process and apparatus for manufacturing yarn products comprised of an inner core of fibers and an outer layer of fibers. In the process, first fibers have a pre-twist imparted thereto to form a strand which becomes the inner core of the yarn and the pre-twist is retained by passing the yarn between two pinch points. While between the two pinch points, second fibers are juxtaposed to the strand and any untwisting tendency by the inner strand will tend to twist the outer layer of fibers. Optionally, the yarn may undergo a further twisting operation while between the two pinch points after the second fibers have been deposited.
