Description

TECHNICAL FIELD

[0002] With the development of social economy, people's living standards continue to improve, and for clothing textiles, in addition to pursuing wearing comfort, more and more attention is paid to its fashion and functionality, and unique style and various functions such as antibacterial, antistatic and the like are pursued. In order to meet the needs of consumers, it is an important task for the textile industry to continuously develop new yarns and fabrics. With the development of science and technology, the competition in the textile market is becoming more and more fierce, and various manufacturers are constantly developing towards high-end, high-grade, good technical content and high added value in order to maximize profits.

[0003] Paper yarn refers to dividing a paper roll into narrow strips, spinning on a spinning machine, making a 0.1mm to 0.5mm thread, and then making a certain diameter circular textile thread through a winding machine. Paper yarn can be woven, made into cloth, made into clothes, made into handicrafts, and woven. Paper yarn is a new type of yarn produced by a method similar to papermaking, mainly using wood fibers. At present, only a small amount of production exists in Japan, the Netherlands and other countries. Its advantages are light weight, similar to linen fabric, moisture regulating function, odor removal function, and resistance to mold, fleas, harmful gases, and static electricity. The disadvantages of paper yarn are that it is easy to break, so it is easy to break during production and after being made into thread, making the production of paper yarn difficult and the service life short. At the same time, paper yarn is easily affected by temperature when plying, resulting in low plying efficiency and further reducing service life. SUMMARY

The twist is transmitted from the bottom to the top along the length direction of the polyester / viscose mixed roving until the polyester / viscose mixed sliver outputted by the drafting system is twisted into the polyester / viscose mixed roving. When the magnetic size of the electromagnetic coil 21 is kept constant, when the density of the polyester / viscose mixed roving passing through the working surface of the ring 23 is large, the thick polyester / viscose mixed roving covers the working surface of the ring 23, thus the magnetic attraction force on the ring 23 is reduced, thus the linear speed of the ring 23 is increased, thus the generated twist is increased. When the density of the polyester / viscose mixed roving passing through the working surface of the ring 23 is small, the thick polyester / viscose mixed roving covers the working surface of the ring 23, thus the magnetic attraction force on the ring 23 is increased, thus the linear speed of the ring 23 is reduced, thus the generated twist is reduced, thus the twist factor is uniformly distributed along the length direction of the polyester / viscose mixed roving. The difference between the linear speed of the ring 23 and the linear speed of the bobbin 17 makes the polyester / viscose mixed roving continuously wound on the bobbin 17. Synchronously, the lifting motor drives the lifting plate 18 to periodically move up and down, thus the polyester / viscose mixed roving is wound on the bobbin 17.

[0036] The sixth step is paper yarn processing: the paper yarn is processed by selecting paper with a density of 10 g / m 2 The following paper is used as raw material, and a special paper cutter is used to cut the selected paper into a paper strip with a width of less than 2 mm. The paper strip is twisted by a ring spinning frame to obtain paper yarn. In this process, the paper strip is continuously fed into the front roller of the drafting system of the ring spinning frame, and then continuously outputted by the front roller. The outputted paper strip is directly twisted into the required paper yarn under the action of the core yarn twist. The obtained paper yarn is continuously wound on the bobbin 17.

[0037] The paper yarn is fed in continuously through the back drafting roller pair of the drafting system of the ring spinning frame, and the fed-in polyester / viscose mixed roving is subjected to drafting action of the drafting zone between the back drafting roller pair and the middle drafting roller pair of the drafting system and the drafting zone between the middle drafting roller pair and the front drafting roller pair, so that a polyester / viscose mixed sliver with a certain width is obtained. In the drafting process, the polyester / viscose mixed roving is subjected to a finishing drafting action of 1.1 times or less in the back drafting zone. In the finishing drafting process, the fibers in the polyester / viscose mixed roving are tensioned, so that the internal friction field generated by the friction force between the fibers in the polyester / viscose mixed roving is increased as a whole and the consistency is improved. The polyester / viscose mixed roving is subjected to a drafting action of 50 times or more in the front drafting zone. In the drafting process, the fibers in the polyester / viscose mixed roving keep slow movement in the front drafting zone under the control of the internal friction field, until they move to the space between the drafting top roller and the drafting bottom roller of the front drafting roller pair. At this time, the required number of fibers are extracted from the front drafting roller pair which rotates rapidly as a whole, and the extracted fibers keep a completely untwisted state. The extracted fibers form a polyester / viscose mixed sliver with a certain width under the pressing of the front drafting roller pair. The prepared paper yarn is fed in after being pressed by the front drafting roller pair of the drafting system, and the pressing point is located at the center of the polyester / viscose mixed sliver. The polyester / viscose mixed sliver and the paper are output together from the drafting system, and are directly twisted into the required paper yarn composite yarn under the action of the composite yarn twisting twist. The prepared paper yarn composite yarn is continuously wound on the spinning tube 17. The direction of the composite yarn twisting twist is opposite to the direction of the core yarn twisting twist, the composite yarn twisting twist is greater than the core yarn twisting twist. In the twisting process, the fibers in the polyester / viscose mixed sliver with a certain width and no twist are wrapped around each other, and in the wrapping process, the paper yarn located in the middle is wrapped at the center, and the wrapping direction of the fibers in the polyester / viscose mixed sliver is opposite to the twist of the paper yarn, so that the twist of the paper yarn is partially removed in the wrapping process. The paper sheet in the removal process is hindered by the wrapped mixed fibers, until both reach a balanced state. Then, due to the tension of the paper, a certain air layer is formed at the center of the paper yarn, so that a paper yarn composite yarn with the paper yarn at the center and the blended short fiber yarn at the outside is prepared. The prepared paper yarn composite yarn is continuously wound on the spinning tube 17.

[0038] The outer wrapping yarn density is 40 S The composite yarn of the blended short fiber yarn with a blending ratio of T65 / R35 and a paper yarn with a linear density of 80 S The corresponding process parameters are as follows:
