Problems solved by technology

However, after the super-large draft increases the draft ratio of the spun yarn, the yarn slivers in the front area will spread and the compactness will decrease, resulting in the widening of the output yarn sliver from the nip of the front roller, the expansion of the twisting triangle area, the increase of side fibers, and the increase of yarn hairiness. Yarn hairiness doubles again after winding, which poses a problem for subsequent processing

Embodiment Construction

[0008] Depend on figure 1 As shown, the sliver is fed into the rear roller (11), and after the fiber strands are held and output by the front roller (7) and the front rubber roller (6), the iron soleplate (1) through temperature regulation, and finally the yarn enters the yarn guide hook ( 13), then the traveler (14) is driven by the rotation of the spindle to rotate along the steel ring (15) runway and the yarn is twisted and wound onto the bobbin (16). The temperature-regulating ironing device is fixed on the car platform (12), and is made up of base plate (1), electric heating element (2), thermostat (3), pressing plate (4) and shell (5). The thermostat (3) is composed of a bimetal thermostat and a conductive spring. When energized, the heating wire generates heat, and the temperature of the bottom plate (1) is continuously supplied through the thermostat (3). The heat irons the yarn. The shell (5) is made of dry hardwood or pottery, and has the effect of heat insulation....

Abstract

The invention relates to a three-roller superlarge-drafting ironed yarn production method. A device is arranged at the position of a carriage table top and mainly composed of a baseplate, an electric heating element, a thermolator, a press plate and a shell. The three-roller superlarge-drafting ironed yarn production method can be applied to a three-roller superlarge-drafting spinning machine for simple technical transformation, and the device is mounted on the carriage table top. Fiber roving is output from a front jaw for temperature-adjusting ironing, and yarn is fully shaped, so that hairiness of resultant yarn is reduced, and fibers in the yarn are uniform stressed. Compared with the prior art, the device has the advantages of simplicity and convenience in mounting and high performance-cost ratio.

Description

technical field [0001] The invention relates to the new field of spinning technology, in particular, an ironing device is installed on a super-large draft spinning frame to reduce hairiness and improve yarn smoothness. Background technique [0002] The problem of yarn hairiness and strength has long attracted the attention of the textile industry at home and abroad, and many methods have been used to control hairiness and strength. For example, the use of compact spinning technology eliminates the spinning triangle area, and twists after shrinking and drafting the strands, thereby reducing hairiness and increasing yarn strength. The yarn is strong, but the cost of compact spinning technology is high, energy consumption is high, and management is inconvenient. [0003] Superdraft spinning is done in the same way as ring spinning, the sliver does not break, so optimum stretching is achieved and the fibers are oriented in the spun yarn. At the same time, the ultra-large draft ...
