[0019] like Figure 1 As shown, in some embodiments, the twist of the first strand 2 and the second strand 3 is 300-800 twists / m. The strength of the first strand 2 and the second strand 3 is mainly determined by the twist. The greater the twist, the greater the strength. In this embodiment, by setting the twist of the first strand 2 and the second strand 3 to 300-800 twists / m, the chenille yarn is relatively soft, and thus suitable for making skin-friendly items such as sofa covers and bedspreads.

In this embodiment, the number of the pay-off mechanism and the liquid storage tank 6 is three. The wind tube 5 and the liquid storage tank 6 are both fixed on the frame 4. The liquid storage tank 6 is connected to a liquid outlet pipe, and a valve is fixed on the liquid outlet pipe. The pay-off mechanism includes a fixed frame 7 and a guide ring 8, both of which are provided on the frame 4.

When the twisting machine in this embodiment is used, taking the above S3 step as an example: According to the chemical properties of the first strand 2, the second strand 3 and the feather yarn 1, specific chemical reagents are prepared, and the three chemical reagents are added to the three liquid storage tanks 6 respectively, so that the second guide roller 11 is located below the liquid surface, and the three pay-off drums 9 wound with the first strand 2, the second strand 3 and the feather yarn 1 are respectively installed on the three fixing frames 7, and the free end of the first strand 2 passes through one of the guide rings 8 and passes around the first guide roller 10, the second guide roller 11 and the third guide roller 12 in turn, and then the free end of the first strand 2 passes through one of the sets of perforations 14 and is fixed on the twisting mechanism, and the above operation is repeated to twist the second strand 3 The free ends of the first and second strands 2 and 3 are fixed on the twisting mechanism, and the twisting mechanism twists the first strand 2 and the second strand 3 and sandwiches the feather yarn 1 in the middle. During this process, the yarn is first treated with a chemical reagent to improve the surface properties of the yarn and reduce the adhesion of the fluff without damaging the yarn. Then the fan 13 works to introduce the external natural wind into the air duct 5, and blows away the fluff on the surface of the yarn by accelerating the flow of air. It does not directly produce strong friction with the yarn, so it does not damage the yarn and dries the yarn at the same time. The blown away fluff is filtered through the filter 15, and finally the machine is stopped and the twisted chenille yarn is removed. In summary, the twisting machine in this application can process the fluff on the surface of the yarn when in use without causing damage to the yarn, avoiding the influence of the fluff on the twisting process, thereby ensuring the strength and stability of the yarn, and is therefore more practical.

At the same time, the end of the wire-paying drum 9 first contacts and overlaps with the inclined surface of the triangular block 18. Through the transition effect of the inclined surface, the triangular block 18 and the limiting slide 17 are forced to slide together to the limit position, and the return spring 19 is squeezed. After that, the end of the wire-paying drum 9 contacts and overlaps with the plane of the triangular block 18, and the return spring 19 is reset to the natural state. The block 18 and the limiting slide 17 slide to the initial position together.
