A ball 17 is provided at the end of the support column 16 away from the processing cylinder 10, and the ball 17 contacts the inner wall of the processing box 9.

[0052] The working principle and beneficial effects of the above technical solution are as follows: to produce chenille yarn, first prepare the first feather yarn 4, the second feather yarn 5, the third feather yarn 6 and the fourth feather yarn 7, and place the first feather yarn 4 and the second feather yarn 5 in parallel. The first feather yarn 4 adopts antibacterial fiber, the second feather yarn 5 adopts low melting point hot melt fiber, and the third feather yarn 6 and the fourth feather yarn 7 adopt polyester feather yarn; then the third feather yarn 6 and the fourth feather yarn 7 are cross-spirally wound around the outside of the first feather yarn 4 and the second feather yarn 5 to obtain a feather yarn semi-finished product; then heat the feather yarn semi-finished product to melt the second feather yarn 5, and the second feather yarn 5 is bonded to the first feather yarn 4. At the same time, the third feather yarn 6 and the fourth feather yarn 7 are fixed to the outside of the first feather yarn 4 and the second feather yarn 5 through the hot-melt second feather yarn 5 to obtain a feather yarn assembly 3, which improves the structural stability of the feather yarn assembly 3 and avoids separation and falling off due to washing; then prepare the first core yarn 1 and the second core yarn 2. The first core yarn 1 adopts antibacterial fiber, the second core yarn 2 adopts polyester The chenille yarn is twisted with the first core yarn 1 and the second core yarn 2 by the existing process, and the feather yarn component 3 is sandwiched between the first core yarn 1 and the second core yarn 2 to obtain a chenille yarn body 8; finally, the chenille yarn body 8 is subjected to antibacterial treatment to obtain an antibacterial chenille yarn finished product; the first core yarn 1 and the first feather yarn 4 of the antibacterial chenille yarn finished product are both made of antibacterial fiber, which can enhance the antibacterial performance of the chenille yarn, reduce the spread of bacteria, reduce the risk of infection, and protect the health and safety of users; through the antibacterial treatment, an antibacterial layer can be prepared on the outside of the third feather yarn 6 and the fourth feather yarn 7. By providing the antibacterial layer, the antibacterial performance of the chenille yarn can be further enhanced, and the growth of bacteria such as Staphylococcus aureus and Escherichia coli can be effectively inhibited, thereby improving the hygiene and safety of the chenille yarn product and reducing the risk of disease transmission. In addition, by enhancing the antibacterial performance, the frequency of cleaning of the chenille yarn product can be reduced, and the service life of the chenille yarn product can be extended.

[0053] The antibacterial treatment includes roughening the surface of the chenille yarn body 8 using a surface treatment device, then immersing the chenille yarn body 8 in an antibacterial liquid, taking out the chenille yarn body 8 after immersion for a preset time, and drying it, wherein the antibacterial liquid includes but is not limited to silver ion antibacterial liquid, nano zinc oxide antibacterial liquid, and copper ion antibacterial liquid;

[0054] The surface of the chenille yarn body 8 is roughened by a surface treatment device, including passing one end of the chenille yarn body 8 through the yarn feeding port and the yarn outlet in sequence and winding it around the yarn taking-up roller, and then controlling the yarn taking-up roller to start at a preset time interval, thereby realizing the interval winding of the chenille yarn body 8. When the yarn taking-up roller stops working, the electric push rod 12 starts and performs a reciprocating telescopic motion. At the same time, the low-temperature plasma generator 13 starts to emit plasma to the outside of the feather yarn component 3, and the plasma bombards the outside of the feather yarn component 3, thereby generating tiny pits on the surface of the feather yarn component 3, making the surface of the feather yarn component 3 rough, and improving the roughness of the surface of the feather yarn component 3. When the electric push rod 12 is extended, it can drive the baffle 11 on the left to move to the left, and the baffle 11 drives the processing cylinder 10 to move to the left synchronously. When the baffle 11 moves, it can press the feather yarn component 3 at the through hole through the through hole. The tilting of the feather yarn component 3 can increase the contact area with the plasma, thereby generating more tiny pits. At the same time, when the processing cylinder 10 slides to the left, The sliding column 15 slides in the spiral groove 14, thereby driving the processing cylinder 10 to rotate. The rotation of the processing cylinder 10 drives the low-temperature plasma generator 13 to rotate, so that the plasma is emitted in a spiral shape, thereby adapting to the spirally wound second core yarn 2 and avoiding the first core yarn 1, roughening the second core yarn 2, and reducing the bombardment of the first core yarn 1. The low-temperature plasma generators 13 on both sides of different baffles 11 are set at different angles, which can further increase the bombardment effect on the surface of the feather yarn assembly 3, thereby producing more tiny pits. When the electric push rod 12 retracts, the processing cylinder 10 rotates in the opposite direction, and the baffle 11 drives the feather yarn assembly 3 to tilt in the opposite direction. The low-temperature plasma generator 13 can roughen the other side of the feather yarn assembly 3, further improving the roughness of the surface of the feather yarn assembly 3. As the roughness of the surface of the feather yarn assembly 3 increases, when the chenille yarn body 8 is immersed in the antibacterial liquid, the combination effect of the antibacterial liquid and the chenille yarn body 8 can be improved, thereby enhancing the long-lasting antibacterial performance of the chenille yarn body 8.

[0077] Antibacterial performance testing:

[0078] The antibacterial properties of the chenille yarns prepared in Examples 1 to 3 and Comparative Example 1 were tested according to GB / T 20944.3-2008 "Evaluation of Antibacterial Properties of Textiles (Part 3): Oscillation Method".

[0080]

[0081] From the data in Table 1, it can be seen that Comparative Example 1 uses polyester fiber without adding antibacterial agent, and its antibacterial rate is less than 5%. It can be seen that the chenille yarn produced in Comparative Example 1 does not have an active antibacterial function. Compared with Comparative Example 1, the chenille yarn in Examples 1 to 3 has significantly improved antibacterial performance by using the first core yarn 1 and the first feather yarn 4 made of antibacterial fiber, indicating that the first core yarn 1 and the first feather yarn 4 are both made of antibacterial fiber, which can greatly enhance the antibacterial performance of the chenille yarn; It can be seen from Examples 1 to 3 that after multiple washings, the chenille yarn produced by Examples 1 to 3 still has antibacterial ability. By comparing Example 1 with Example 2 and Example 3, it can be seen that by performing antibacterial treatment on the chenille yarn body 8 in Example 1, the antibacterial effect of the chenille yarn can be prolonged, so that the chenille yarn maintains a high antibacterial rate after multiple washings, thereby improving the antibacterial performance of the chenille yarn.
