DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0017] like Figure 1-Figure 4 As shown, an antibacterial and deodorizing chenille yarn proposed in an embodiment of the present application comprises a first core 1, a second core 2 and a feather yarn 3, the first core 1 and the second core 2 sandwich the feather yarn 3 between the two by twisting, the first core 1 comprises an antibacterial yarn 101 and a deodorizing yarn 102, and the two are twisted into strands, the second core 2 comprises a hygroscopic yarn 201 and a breathable yarn 202, and the two are twisted into strands, the antibacterial yarn 101 and the deodorizing yarn 102 are twisted into the first core 1, and the hygroscopic yarn 201 and the breathable yarn 202 are twisted into the second core 2, and the first core 1 and the second core 2 are twisted to sandwich the feather yarn 3 in the middle, so as to prepare the chenille yarn, so that the chenille yarn has good moisture absorption and breathability effects while having the existing advantages, and at the same time, it also has good antibacterial and deodorizing effects, thereby improving its hygienic performance; In this solution, the feather yarn 3 is used as the yarn core, and the first core 1 and the second core 2 are used as the yarn surface layer. The yarn surface layer is not only moisture-absorbent and breathable, but also has good antibacterial and deodorizing effects, thereby improving the overall hygienic performance of the chenille yarn.

[0018] like Figure 2As shown, in some embodiments, the antibacterial yarn 101 is composed of a plurality of silver ion fibers twisted together. The silver ion fiber is an antibacterial viscose fiber that uses nano-scale processing technology to uniformly add nano (silver, titanium) inorganic composite antibacterial agents to cellulose fibers. The antibacterial ability of nano silver is more than 200 times that of micron-level silver ions. Silver ions can very quickly adsorb ammonia and deteriorated proteins thereon to reduce or eliminate odors. Silver ions have very high biological activity, which means that silver ions can easily combine with other substances to coagulate proteins inside and outside the bacterial cell membrane, thereby blocking the respiration and reproduction process of the bacterial cells, making it have good antibacterial properties. The deodorizing yarn 102 The bamboo green fiber is an environmentally friendly green fiber that is twisted together by multiple bamboo green fibers. The special ultra-fine pore structure inside the fiber gives it a strong adsorption capacity. It can absorb harmful substances such as formaldehyde, benzene, toluene, ammonia, etc. in the air and eliminate bad odors. It also has anti-ultraviolet function. The ultraviolet transmittance of cotton is 25%, and the ultraviolet transmittance of bamboo green fiber is less than 0.6%. Its anti-ultraviolet ability is 41.7 times that of cotton. By using bamboo green fiber to make the deodorizing yarn 102, the deodorizing effect can be effectively improved. The antibacterial yarn 101 and the deodorizing yarn 102 both use multiple fiber filaments twisted together to ensure that they resist deodorization while also improving their own strength.

[0019] like Figure 2 As shown, in some embodiments, the moisture-absorbing yarn 201 is formed by twisting a plurality of bamboo fiber strands together. The bamboo fiber is a cellulose fiber extracted from naturally grown bamboo. It has the characteristics of good instantaneous water absorption, strong wear resistance and good dyeability. When the yarn is wet, it can absorb moisture on the surface, so that it can be quickly air-dried to avoid moisture breeding bacteria. At the same time, it has natural antibacterial, antibacterial, mite removal, deodorization and other functions, thereby further improving the antibacterial and deodorizing effects of the chenille yarn. The breathable yarn 202 is formed by twisting a plurality of regenerated cellulose fiber strands together. The regenerated cellulose fiber is a natural cellulose fiber. The cellulose fiber is made of natural cellulose (cotton, linen, bamboo, trees, shrubs, etc.) as raw materials, without changing its chemical structure, but only changing the physical structure of natural cellulose, so as to produce regenerated cellulose fiber with better performance. Its structural composition is similar to that of cotton, but the difference is that its hygroscopicity and air permeability are better than those of cotton fiber. It can be said that it has the best hygroscopicity and air permeability among all chemical fibers, and is known as "breathing fabric". Its good air permeability can effectively improve the antibacterial and deodorizing effect of chenille yarn. Both the hygroscopic yarn 201 and the breathable yarn 202 are made of multiple fiber strands twisted together, so that while ensuring its hygroscopicity and air permeability, its own strength is also improved.

[0020] like Figure 3As shown, in some embodiments, the feather yarn 3 is formed by twisting flax fiber and polyester fiber. Flax fiber is a natural fiber with many excellent properties. It absorbs moisture and dissipates heat, is health-care and antibacterial, anti-fouling and anti-static, UV-resistant, and has excellent flame retardant effect. Polyester is a fiber-forming polymer made by esterification or ester exchange and polycondensation reaction of purified terephthalic acid or dimethyl terephthalate and ethylene glycol as raw materials. The fiber made by spinning and post-treatment has the greatest advantage of good wrinkle resistance and shape retention. By twisting flax fiber and polyester fiber to form the feather yarn 3, it has good moisture absorption and heat dissipation, antibacterial and anti-fouling properties, as well as good wrinkle resistance and shape retention, thereby improving its practicality.

[0021] like Figure 5-Figure 10 As shown, a production process of an antibacterial and deodorizing chenille yarn proposed in one embodiment of the present application comprises the following steps: S1: preparing feather yarn 3, twisting flax fiber and polyester fiber through a twisting machine to form feather yarn 3; S2: preparing a first core 1, twisting a plurality of silver ion fibers through a twisting machine to form an antibacterial yarn 101, then twisting a plurality of bamboo leaf green fibers through a twisting machine to form a deodorant yarn 102, and finally twisting the antibacterial yarn 101 and the deodorant yarn 102 through a twisting machine to form the first core 1; S3: preparing a second core 2, twisting a plurality of bamboo fibers through a twisting machine to form a hygroscopic yarn 201, then twisting a plurality of regenerated cellulose fibers through a twisting machine to form a breathable yarn 202, and finally twisting the hygroscopic yarn 201 and the breathable yarn 202 through a twisting machine to form a second core 2; S4: preparing yarn, twisting the first core 1 and the second core 2 through a twisting machine and sandwiching the feather yarn 3 in between, thereby forming yarn; In the above-mentioned steps S1, S2, S3 and S4, the twisting machine comprises: The base 4 is provided with a group of transmission rollers 5 at both the upper and lower ends. Preferably, the number of the transmission rollers 5 in the same group is two. In actual use, the two transmission rollers 5 in the same group rotate synchronously in opposite directions under the action of the servo motor, and the two transmission rollers can clamp and transmit the yarn or assist in transmission; The conical cylinder 6 has a tube body connected at its bottom end and the tube body is rotatably connected to the base 4. A motor 7 is provided on the base 4 and the output shaft of the motor 7 is connected to the tube body through a gear assembly 8. Preferably, the gear assembly 8 includes two bevel gears, which are respectively fixed on the output shaft of the motor 7 and the tube body and the teeth of the two are meshed. When the motor 7 does work, it can drive the conical cylinder 6 to rotate through the gear assembly 8. The outer surface of the conical cylinder 6 is provided with a plurality of grooves 9 distributed in an annular shape. The bottom end of the groove 9 is connected to the tube body through a through hole 10. The groove 9 can be used to place one or a strand of silk thread alone, and the silk thread can be inserted into the tube body through the through hole 10. The mounting cylinder 11 is coaxially fixed on the top of the conical cylinder 6. A plurality of mounting rods 12 are rotatably penetrated on the mounting cylinder 11. The plurality of mounting rods 12 correspond to the plurality of grooves 9 respectively. A linkage 13 is arranged on the base 4. When the conical cylinder 6 rotates, the linkage 13 drives the plurality of mounting rods 12 to rotate synchronously. When twisting (twisting), a separate silk thread reel (the silk thread wound into a reel may be a separate antibacterial yarn 101 or the first wire core 1 after twisting into strands) is fixed on the mounting rod 12. Since there are a plurality of mounting rods 12, the silk thread reels to be twisted may be fixed separately, and then the ends of the silk threads are clamped in the groove 9, and then the tube body at the bottom of the conical cylinder 6 is movably penetrated through the perforation 10. Finally, the ends of the plurality of silk threads are pinched together and passed through a group of transmission rollers 5 and two transmission rollers located below. 5 clamps the ends of the kneaded silk threads and assists in transmission. During the transmission process, the motor 7 drives the conical cylinder 6 to rotate. At this time, under the linkage of the linkage 13, several mounting rods 12 rotate synchronously to release the silk thread cylinder. While releasing the silk thread, the rotation of the conical cylinder 6 drives several silk threads to rotate. Since the two transmission rollers 5 below clamp and transmit the kneaded silk threads, several silk threads are twisted into strands when the conical cylinder 6 rotates. It should be noted that when steps 1, 2 and 3 are twisted, the above operations are followed. Only in step 4, there is a slight difference. The upper and lower sets of transmission rollers 5 need to be enabled at the same time. The two sets of transmission rollers 5 clamp and transmit the feather yarn 3, so that the section of the feather yarn 3 between the two sets of transmission rollers 5 is in a straight state, and then the first core 1 and the second core 2 are twisted on its surface; In the present scheme, the wire drum is fixed on the mounting rod 12, and different wires are respectively clamped in the groove 9, and then pass through the tube body of the conical tube 6 through the perforation 10, so that the different wires are first separated and then conically gathered. At the same time, by utilizing the linkage of the linkage part 13, when the conical tube 6 rotates for twisting, the mounting rod 12 rotates synchronously for wire release. During the wire release process, the wires are effectively separated and do not contact each other to avoid knotting. They will only contact when they are conically gathered and finally twisted into strands, which makes the twisting stable, thereby improving the twisting quality.

[0022] like Fig. 9 As shown, in some embodiments, the linkage 13 includes a sleeve 1301 arranged on the base 4 and coaxial with the mounting tube 11, a bevel gear ring 1302 is fixedly provided at the bottom end of the sleeve 1301, and a bevel gear 1303 is fixedly provided at one end of a plurality of mounting rods 12 close to each other, and the plurality of bevel gears 1303 are all meshed with the teeth of the bevel gear ring 1302. When the conical tube 6 drives the mounting tube 11 to rotate, the plurality of bevel gears 1303 are all meshed with the teeth of the bevel gear ring 1302. Since the position of the bevel gear ring 1302 is fixed, the bevel gear 1303 drives the mounting rod 12 to rotate.

[0023] like Fig. 9 As shown, in some embodiments, a first limit plate 14 is fixedly provided on the mounting rod 12, and a second limit plate 15 is threadedly sleeved on the end of the mounting rod 12 away from the bevel gear 1303, and a wire reel wound with wire is sleeved on the mounting rod 12, so that one end of the wire reel overlaps with the first limit plate 14, and then the second limit plate 15 is threadedly sleeved, so that the second limit plate 15 cooperates with the first limit plate 14 to clamp and resist the wire reel, and the friction force is utilized to fix the wire reel, and the method of fixing or releasing the fixation is relatively simple and convenient.

[0024] like Fig.10 As shown, in some embodiments, a slide groove 16 is provided on the opposite sides of the inner wall of the groove 9, and a support plate 17 is slidably provided in the two slide grooves 16. A wire hole 18 is penetrated through the support plate 17, and a spring 19 is connected between the support plate 17 and the inner wall of the slide groove 16. Preferably, a slide rod is provided in the slide groove 16, and the support plate 17 is slidably sleeved on the slide rod, and the spring 19 is sleeved on the slide rod, thereby guiding the spring 19. Since the silk thread is wound around the silk thread drum in a left-right manner, the silk thread is also wound left-right when the thread is released. The wire is paid out in sequence. In actual use, the end of the wire is movable through the wire hole 18, and the spring 19 applies elastic force, so that the support plate 17 can apply a certain elastic resistance to the wire. Through the elastic resistance, during the wire paying out process, even if the wire is paid out back and forth, the elastic resistance of the spring 19 can be used to make the support plate 17 slide along the slide groove 16, so as to adaptively adjust the tension of the wire, so that during the wire paying out process, the wire will not be loose and scattered in the section between the wire drum and the twisting position, so as to ensure the twisting quality.

[0025] like Figure 8 As shown, in some embodiments, a first storage box 20 is provided on the base 4, and the bottom end of the first storage box 20 is connected to an annular shell 21 through a conveying channel, and an inner wall of the annular shell 21 is provided with a first sponge ring 22. Preferably, an adhesive can be placed in the first storage box 20. When the first core 1, the second core 2 and the feather yarn 3 are twisted in step S4, the feather yarn 3 moves through the first sponge ring 22, and the adhesive in the first storage box 20 is transported to the annular shell 21 through the conveying channel, thereby impregnating the first sponge ring 22. When the feather yarn 3 is transmitted, it will press the first sponge ring 22. Thus, the adhesive is coated on the surface of the feather yarn 3. The adhesive is made of high wet modulus viscose fiber. The high wet modulus viscose fiber has a high degree of polymerization, strength and wet modulus. In a wet state, the unit linear density can withstand a load of 22.0N per tex, and the wet elongation under this load does not exceed 15%. The adhesive is coated on the feather yarn 3, so that when the first core 1 and the second core 2 are twisted, the connectivity between the feather yarn 3, the first core 1 and the second core 2 can be effectively improved, so that when the chenille yarn is pulled, the three will not become loose, thereby improving the overall strength of the chenille yarn.

[0026] like Fig.10 As shown, in some embodiments, the outer surface of the mounting tube 11 is provided with a plurality of second storage boxes 23, and the plurality of second storage boxes 23 correspond to the plurality of support plates 17 one by one, respectively. An annular groove is provided on the inner wall of the thread hole 18, and a second sponge ring 24 is provided in the annular groove. The second storage box 23 is connected to the annular groove via a delivery pipe 25. Preferably, a liquid finishing agent can be added to the second storage box 23. When the first thread core 1, the second thread core 2 and the feather yarn 3 are twisted in step S4, the first thread core 1 and the second thread core 2 each move through their corresponding thread holes 18, and move through the second sponge ring 24 in the thread hole 18, and the finishing agent in the second storage box 23 will pass through. It flows into the annular groove through the conveying pipe 25, thereby impregnating the second sponge ring 24. During twisting transmission, the first core 1 or the second core 2 will compress the second sponge ring 24, and the second sponge ring 24 will coat the finishing agent on the first core 1 or the second core 2. Preferably, the finishing agent is water-based polyurethane. By coating the outer surface of the first core 1 and the second core 2 with water-based polyurethane, the water-based polyurethane is a low-VOC finishing agent that is resistant to low temperature, embrittlement, friction, high tensile strength, good elasticity, and corresponding affinity. It can improve the bonding force between fibers, reduce yarn hairiness, reduce static electricity, and is beneficial to anti-pilling, thereby improving the quality of the yarn after twisting.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
