摘要： A method for making an elastic core yarn includes covering an elastic core having a fiber of natural rubber with metric count 200-1000 dtex with a cotton-based covering yarn. The elastic core and the covering yarn are conveyed such that the covering yarn laterally attains a proximity of the elastic core in a wrapping space. The covering yarn is helically wrapped about the elastic core. The conveying speed, and therefore the winding/unwinding speed, is selected such that the elastic core is stretched to a stretching ratio of at least two, and the covering yarn becomes twisted with a final twist direction opposite to its initial twist direction, and forms T coils per length unit of the elastic fiber set between a minimum value T0 and a maximum value T1. An elasticized yarn is thereby obtained, and a fabric, in particular a denim type fabric, is manufactured from this yarn.

摘要： An automated apparatus produces braided yarn starting from strands for spinning into yarn. A controller provides the automation. A tension roller holds the plurality of strands in tension. A spinning and/or twisting block has pathways extending through it and each pathway contains one tensioned strand. The spinning and/or twisting block includes air jets operated by valves, each air jet acts on one tensioned strand to a produce a twisted strand within the pathway. A take-up apron receives each twisted strand while maintaining the twist of each twisted strand. A tensioning take-up roll for each twisted strand receives each twisted strand from the take-up apron. A grooved cam with fork guide moves the twisted strand. A ring with booster jets directs a vortex of pressurized air to the twisted strands to produce a braided strand. Finally, a winding machine winds the braided strand received from the ring with booster jets.

摘要： The present application of the invention aims at improving knot strength of a twisted yarn without compromising circularity, with respect to various yarns including a fishing line. For such purpose, the present application of the invention provides a yarn including a multifilament subjected to two twisting processes in different directions, and a coating resin that covers a surface of the multifilament; wherein the multifilament is subjected to a first twist in one direction, and then to a second twist in a direction opposite to that of the first twist, without being doubled with another yarn.

摘要： A process of producing an assembled yarn, including the steps of providing two or more yarns moving downstream from a supply to a take-up, inserting alternating-direction zones of twist into at least one of the yarns, the at least one yarn having an area of zero twist between said alternating direction zones of twist, combining the at least two yarns to form a single, integrated yarn strand, and intermittently exposing the yarn strand to an air blast to create a zone of intermingled yarns at spaced-apart points along the length of the yarn strand to prevent torsional movement of one yarn relative to the other yarn. According to one preferred embodiment of the invention, the step of exposing the yarn strand to an air blast includes the step of intermingling the yarns at the areas of zero twist.

摘要： A process and apparatus for making alternate S and Z twist plied yarn from individual singles yarns includes the steps of tensioning the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction, snubbing the yarn to restrain ply twisting so the twist in the singles yarn can equalize itself, stopping the forward movement of the yarn, then bonding the ply-twisted yarns at a node while applying twist, stopping the twisting operation, then repeating the procedure while twisting in the opposite direction. The ply twisted yarn has a lower defect level of less than 2.5 defects per 100 inch length of yarn.

摘要： A process for producing a yarn with alternate twist, which is obtained by intermittently varying the distance which the twist extends back upstream of a false twister. The variation in the distance is produced without braking the yarn and is achieved by means of a blocking device acting intermittently at a point located close to the false twister. The duration of action of the blocking device approximately corresponds to the time taken by a given point on the yarn to cover the distance from a delivery member to the false twister.

摘要： Self-twisting yarns are made by a system in which a strand twisting device is engaged with the strand and moves at strand speed to twist the oppositely-extending sections of the strand in opposite directions. The strand is brought together with another strand and released, enabling it to untwist and twist itself to the other strand. Various arrangements are disclosed for maximizing the distance between twist reversal nodes, for cabling plied yarns together, for strengthening the strands, for reducing the tensile stresses imposed on the strands and for producing unique products with non-uniform node spacing or unequal strand lengths between adjacent pairs of nodes.

摘要： False-twisted yarn strands are separately carried around a guide wheel and the nodes thereof are brought together and locked by mechanical entanglement, after which the strands are self-twisted. Embodiments of entanglement joining devices include reciprocating friction plates which rub the fibers together and twist them, causing joining, the plates being carried on the guide wheel. A needle punching device carried by the wheel is disclosed, the needles being reciprocated by a cam structure within the wheel. In a third embodiment edges of oppositely rotating overlapping discs contact and twist fibers in the node area, causing entanglement.
