Problems solved by technology

The key problem in the spinning process of ordinary ring spinning is: the front roller jaws press the fiber strands into a flat ribbon shape, and under the action of twisting torsion, the fibers in the flat ribbon fiber strands are transferred from inside to outside, when the fibers A certain part has entered the yarn body through internal and external transfer. At this time, the head end of the fiber exposed from the yarn body is out of the grip of the front roller jaw, and cannot enter or wrap around the main body of the yarn body again, thus forming hairiness; when the fiber is in the At the edge of the flat ribbon-shaped fiber strands, the adhesion and cohesion between the fibers and the main body of the twisted strands is weak. As soon as the fibers come out of the nip of the front roller, they are easily changed by the negative pressure suction of the flute tube. The main body of the twisted sliver, at this time, after the fibers are completely separated from the grip of the front roller jaws, they are directly sucked away by the negative pressure of the flute tube to form tow fibers, reducing fiber utilization and ring spinning quality
However, the ironing device involved in this method is only limited to reducing the fiber modulus to improve the fiber's easy torsion and bending properties, and to improve the smoothness of the yarn.
Similarly, the ironing device still brings additional energy consumption problems, and the ironing and spinning effect on some fibers with poor heat sensitivity (such as wool fibers) is poor, and the yarn quality cannot be improved

Embodiment 1

[0021] In the cotton fiber siro spinning process, the yarn quality of ring spinning is improved.

[0022] On the cotton-type ring spinning frame, the negative pressure guiding and catching device is fixedly installed on the pear-shaped suction bagpipe 9 through the base 6, and connected to the suction pipe 9 and the suction channel in the heating part 3. The tuyere 8 generates a negative pressure airflow in the holding groove 7, and the two cotton rovings enter a drafting system of the ring spinning frame through a double bell mouth feeder with a distance of 4 mm. Roller and front roller are output by the front roller nip, and the output two whiskers are converged and twisted into yarn, and the twisted composite yarn immediately enters the holding groove 7 of the heating part 3, and the grip at the air suction port 8 The ratio of the width of the holding groove 7 to the width of the outlet of the holding groove 7 is 1.5-2.0, and the negative pressure airflow in the holding gro...

Embodiment 2

[0024] Improve the yarn quality of ring spinning in wool siro core-spun compound spinning process.

[0025] On the wool-type ring spinning frame, cancel the wool-type single-pipe suction pipe system per spindle, and refit it into a pear-shaped suction pipe 9 for cotton spinning, and the negative pressure guiding and catching device is fixedly installed on the suction pipe 9 through the base 6 on, and connect the suction bagpipe pipe 9 with the suction passage in the heating part 3, and the two wool rovings enter a drafting system of the wool-type ring spinning frame through a double bell-mouth feeder with a distance of 6 mm, and are drawn After drafting by the stretching system, it is output from the front roller nip composed of the front rubber roller and the front roller. The polyester filament unwound from the filament package is output from the rear of the front rubber roller through the front roller nip through the wire guide device. It is located in the middle of the lef...

Embodiment 3

[0027] Improve the forming quality of ramie single yarn in the process of ramie long fiber ring spinning.

[0028] On the ring spinning frame of long hemp spinning, cancel the single-tube suction pipe system of each spindle of long hemp spinning, and refit it into a pear-shaped suction pipe 9 for cotton spinning, and the negative pressure guiding and catching device is fixedly installed on the suction pipe 9 through the base 6 and connect the suction bagpipe pipe 9 with the suction passage in the heating part 3, a ramie roving enters a drafting system of the wool-type ring spinning frame through the feeding horn, after being drafted by the drafting system, it is drawn from The front roller nip output by the front rubber roller and the front roller, the ramie strands output by the front roller nip are twisted into a composite yarn under the action of twisting, and the twisted composite yarn immediately enters the grip of the heating part 3 In the groove 7, the ratio of the widt...

Abstract

The invention relates to a negative pressure guide capturing type smooth and clean spinning device and belongs to the technical field of textile processing. A holding groove is formed in the working face of a heating component, a suction inlet is located in the inner wall of the holding groove, is communicated with a suction channel of the heating component and a channel of a base and is communicated with a suction flute through the base, negative pressure airflow is generated in the holding groove through the suction inlet, fiber at the edge of a fiber strand is guided to be tightly attached to the sliver body for capture, a movable cover board is movably installed on a mechanism on a cover board installation table through a hinge, connection of fine yarns is facilitated, it is ensured that negative pressure airflow enters only from the inlet end of the holding groove in the normal spinning process, and the negative pressure airflow is fully used for guiding and capturing the fiber and holding and winding fiber hairiness. Meanwhile, the ironing type smooth and clean spinning function and the airflow guide capturing type ring spinning function are combined, the fiber is captured more effectively, the fiber hairiness is eliminated more effectively, and the quality of finished yarns is improved. The negative pressure guide capturing type smooth and clean spinning device is reasonable in structure, convenient to operate and easy to use and popularize.

Description

technical field [0001] The invention relates to a negative pressure guiding and catching type soft and smooth spinning device, which belongs to the technical field of textile processing. technical background [0002] Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of weaving, knitting and other post-processes, but also affects the appearance quality of the final product. Especially today, when high-speed shuttleless looms are widely used, reducing yarn hairiness is of great significance. [0003] Yarn hairiness occurs during the spinning process of ring spinning. The key problem in the spinning process of ordinary ring spinning is: the front roller jaws press the fiber strands into a flat ribbon shape, and under the action of twisting torsion, the fibers in the flat ribbon fiber strands are transferred from inside to outside, when the fibers A certain part has entered the yarn body throu...
