Background technology
There is twist liveliness and produce residual torque in the yarn through twisting.The crudy of this residual torque on subsequent product of yarn has impact, causes subsequent machining technology to become more difficult.Therefore, residual torque should be prevented most possibly in spinning industry.
Because staple fibre yarn is formed by twisting by fiber, therefore the residual torque of yarn is mainly subject to the impact of the type of fiber, shape of cross section and the polymerization methods of fiber, the internal structure of yarn etc.The yarn that Barella and Manich has demonstrated different structure theoretically has different stress distribution (Textile Research Journal, 1989,59 (12)).Lord and Mohamed demonstrates friction yarn (DREF-II) and has maximum residual torque (Textile Research Journal, 1974,44 (7)).
For many years, the researcher of textile industry is that the residual torque reducing or eliminate yarn have developed multiple balance method.These methods are divided into permanent disposal method and physics balance method two class.Permanent method for shaping comprises HEAT SETTING, chemical treatment and wet setting etc.Physics balance method also has multiple, and the inner core of yarn is by processing with gas ejecting system, and the hull fibres looping that the outer cotton-wadded quilt of described inner core is similar to DREF-III yarn.The Hong Kong Polytechnic University Tao Xiaoming machined the inner core of revolving cup yarn.The layered structure of shell, thus obtain low moment of torsion single-strand yarn, but described technology is not suitable for ring spun yarn line.In addition, the U.S. Patent No. US6860095B2 of the people such as Tao Xiaoming discloses a kind of method manufacturing sub-thread ring spun yarn line without moment of torsion.According to this patent application, drawn fiber is divided into multiple fiber beam splitting.First each beam splitting of fiber obtains respective twist value during false twisting, is then twisted together to form final yarns.False twisting is controlled, thus realizes the balance of the internal torque of final yarns.And the U.S. Patent No. US7096655B2 that the people such as Tao Xiaoming submit to discloses a kind of method and apparatus for the manufacture of sub-thread ring spun yarn line.In the method, false twist apparatus rotates with first rate, for twisting fiber.After the first twining steps, immediately to initial yarn provide to twist with first in the same way second twist and reverse second twist combine twisting, for spinning final sub-thread ring spun yarn line.And, the ratio of first rate and the second speed is controlled, thus controls the residual torque in final sub-thread ring spun yarn line.Meanwhile, what the patent No.200910161586.9 of the people such as Tao Xiaoming proposed goes for the types such as single thread, strand, cladded yarn for the method and apparatus producing bending false twisting on ring spun yarn line.But above-mentioned patent application is suitable for splitting yarn without torsion loop with laboratory scale manufacture.When the actual needs of large-scale production, Yarn connecting needs to walk around feed carrier, causes repiece difficulty.Especially when spinning low moment of torsion yarn joint, the twist of yarn itself is low, and causing cannot repiece.Patent No.201010507189.5 and No.201010507174.9 proposes production method and the cylindrical shape mechanical false twisting device thereof of low torsion gathered yarn, has been described in detail in the false twister device of the ring throstle that this device proposes in patent No.200910195695.2 and No.201010507171.5; The patent No.201010237244.3 false twister proposed in high-tenacity and low-tension spinning device has two frames be fixed on framework to form.Said apparatus yarn in repiece process all needs the hole of the false twister increased through, makes repiece become incomparable difficulty.Locus and the spatiality of existing spinning section can be changed when installing on existing spinning equipment in above-mentioned patent, the grip hold arc of yarn and front roller is caused to increase, or the angle changed between yarn and twizzle, the change of these parameters adds the physical length of spinning section, have impact on the application of the spinning process theory of existing maturation.
In order to overcome above-mentioned shortcoming, adopt a false twisting disk and spacer rod to the yarn false-twisted of spinning section, the end face of false twisting disk and spinning section in the same plane, thus do not affect the spatiality of existing spinning section, after repiece, by spacer rod, spinning section is pressed to false twisting disk, be convenient to repiece.Because false twisting disk is owing to turning on the contrary thus not affecting the states such as the twist of the original yarn of false twisting disk output, improve the feasibility of technique.And the speed of false twisting disk can regulate the false twisting efficiency reaching and control spinning section on the upside of false twisting disk, thus improves the performance of this section of yarn, finally reaches minimizing breakage, improves the object of yarn property.
Therefore, the object of this invention is to provide the process for spinning ring spun yarn line and device.
Described process and device have the technology characteristics parameter, the Yarn connecting technique that do not change original spinning section output and are easy to the advantages such as operation.Regulate the rotating speed of false twisting disk to reach and improve yarn spinning performance, by improve spinning section the twist, reduce the final yarns twist thus obtain the property of final ring spun yarn line.
