摘要:
The invention relates to core yarns in the textile sector and fabrics obtained from these yarns. The invention particularly relates to a core yarn comprising core spun yarn composed of variable drafted filament yarn and/or elastane yarn at the core part, the method of obtaining said core yarn, and the fabric obtained from this yarn.
摘要:
A spinning machine (1) includes a core yarn supplying device (40) adapted to supply a core yarn (C); a draft device (6) adapted to supply a fiber bundle (F) ; a pneumatic spinning device (7) adapted to produce a spun yarn (Y) by applying twists to the fiber bundle (F) with the core yarn (C) as a core; a tension sensor (9) adapted to detect tension applied to the spun yarn (Y) produced by the pneumatic spinning device (7); and a monitoring section (71) adapted to monitor a yarn quality of the spun yarn (Y) in accordance with a quality monitor reference range for monitoring the yarn quality of the spun yarn (Y) and a detection result of the tension sensor (9).

The device comprises a set of separate, adjacent pivoting arms (5,5',3,3') for each adjacent guide roller (1,1') for lapping filaments, said arms (5,5',3,3') being mounted with independent rotation capability and stable positioning at variable angles, on a support (8) which is fixed adjustably on a single rail (10) on which are also fixed the roving guides, also adjustably, said support (8) being connected to a fixed part of a spinning machine, by means of a resilient arm (17) provided with flexion capability in a horizontal plane.

Um ein Core-Garn zu schaffen, bei welchem die Seele durch den Mantel möglichst gut zur Außenseite des Core-Garns hin abgedeckt ist, wird vorgeschlagen, daß das Core-Garn eine Seele, die eine Drehung mit einer Drehrichtung und einem Drehungsbeiwert α (metrisch) von mindestens ungefähr 80 aufweist, und einen Mantel, der in der Drehrichtung, welche der Drehrichtung der Seele entspricht, um die Seele herum gesponnen ist, umfaßt.
摘要:
A motor (18), which drives a pair of front rollers (17) of a draft part (16), is controlled such that the rotation speed of the pair of front rollers is decreased from a reference speed (N0) to a decelerated speed (N1) and thereafter increased to the reference speed based on a designed thickness profile (DP) including a slub length (L). The yarn length (La) spun while the rotation speed of the pair of front rollers is increased from the decelerated speed to the reference speed is computed in advance. When the rotation speed of the pair of front rollers is decreased from the reference speed to the.decelerated speed, the motor is controlled such that the rotation speed of the pair of front rollers is increased at a point in time at which the yarn length spun from when the rotation speed of the pair of front rollers is started to be decreased reaches a value obtained by subtracting the yarn length computed in advance from the slub length of the designed thickness profile. Therefore, a special yarn that accurately conforms to the designed thickness profile is manufactured.
