Description

Technical Field

[0001] The invention relates to the field of polyester yarn preparation, and in particular to equipment and a method for preparing antibacterial polyester yarn. Background Art

[0002] Antibacterial polyester yarn is a polyester yarn material that is endowed with antibacterial properties by introducing antibacterial ingredients during the production process of polyester fibers. The additional process of antibacterial agents is divided into two methods: raw yarn modification and surface treatment. Raw yarn modification is to mix antibacterial ingredients with polyester during the polymerization reaction stage or melt spinning process of polyester to form a stable antibacterial function in the fiber.

[0003] Due to the high viscosity and poor fluidity of molten polyester, there may be uneven mixing during the mixing process of the antimicrobial agent and the molten polyester, which may cause the antimicrobial agent to be unevenly distributed on the surface of the polyester yarn after spinning, resulting in unstable antimicrobial effect or local failure, thus affecting the overall performance of the fiber, especially in large-scale production, where the distribution of the antimicrobial agent may vary significantly;

[0004] Since some antimicrobial agents have poor thermal stability, excessively high temperatures may cause volatilization or thermal degradation of the antimicrobial agents. Therefore, during high-temperature treatments such as melt spinning and heat setting, the antimicrobial agents may be destroyed or volatilized by the high temperature, which may affect the long-term antimicrobial effect of the antimicrobial polyester yarn.

[0005] And because the antimicrobial agent has persistence (i.e., the duration of the antimicrobial effect), during the use of the antimicrobial polyester yarn, the antimicrobial agent components in the polyester yarn are affected by factors such as air, moisture, and temperature, and its antimicrobial effect will gradually decrease. In addition, because the existing antimicrobial polyester yarns are mostly solid single-layer structures, this structure limits the distribution depth of the antimicrobial agent, resulting in the antimicrobial agent usually only forming a thin layer on the fiber surface or staying through physical adsorption and chemical bonding. At the same time, the solid structure of the antimicrobial polyester yarn lacks a mechanism for storing the antimicrobial agent internally, so there are still problems such as fast release of the antimicrobial agent, short duration of the antimicrobial effect, and easy shedding of the antimicrobial agent.

[0006] Therefore, it is necessary to invent a preparation device and method for antibacterial polyester yarn. Summary of the invention

The first extrusion sleeve 11, the second extrusion sleeve 13 and the third extrusion sleeve 15 are all installed with melt extrusion devices, which are used to mix polyester materials and antibacterial agents and extrude them. The secondary extrusion base 34 and the tertiary extrusion base 36 are both installed with a coating structure, which is used to coat the extruded molten polyester on the solidified polyester filament; the primary wire drawing cabin 31 and the secondary wire drawing cabin 32 are both installed with a wire drawing shaping structure, which is used to stretch the extruded polyester filament into filaments and cool and shape them; a wire-on device is installed between the wire twisting turret 26 and the wire drawing plate 18, which is used to clamp the polyester filaments extruded by the wire drawing plate 18 and pull the thread ends to the wire twisting turret 26.

[0046] In the above embodiments, it should be noted that:

[0047] Add polyester and antibacterial agent to the first feed port 12, start the melt extrusion device in the first extrusion sleeve 11 to mix the molten polyester and antibacterial agent evenly and inject them into the diverter 17, then extrude polyester yarn from the drawing plate, control the upper line device to clamp the polyester yarn extruded by the drawing plate 18 and pull the thread end to the twisting wire rotating frame 26, then the staff fixes the polyester thread end on the outside of the twisting wire rotating frame 26, rotates the twisting wire rotating frame 26 to slowly wind up the polyester yarn; then the extruded polyester yarn is drawn and shaped by the drawing shaping structure in the primary drawing cabin 31, and then introduced into the secondary extrusion base 34 to pass through the coating structure for secondary extrusion, then the drawing shaping structure in the secondary drawing cabin 32 draws the polyester yarn again, and then introduces the tertiary extrusion base 36 to pass through the coating structure for the third extrusion to form a multi-layer polyester yarn structure, and the three extrusions The temperature decreases successively to achieve the following: 1.

In the polyester fiber with a multi-layer structure, the antimicrobial agent can be encapsulated and dispersed in different layers. This multi-layer structure helps to slowly release the antimicrobial agent and reduce its direct contact with external air, humidity, light and other factors, thereby effectively extending the durability of the antimicrobial agent.

[0048] Embodiment 2, as Figure 1 - Figure 5 As shown, a preparation device for antibacterial polyester yarn includes embodiment 1, in addition, the melt extrusion device includes a melt chamber 21, the first extrusion sleeve 11, the second extrusion sleeve 13 and the third extrusion sleeve 15 are all fixedly installed with the melt chamber 21, one end of the melt chamber 21 extends out of the first extrusion sleeve 11, the second extrusion sleeve 13 or the third extrusion sleeve 15, the second extrusion sleeve 13 is installed with a second feed port 14 on the side away from the secondary extrusion base 34, the third extrusion sleeve 15 is installed with a third feed port 16 on the side away from the tertiary extrusion base 36, the first extrusion sleeve 11, the second extrusion sleeve One end extending from the melting chamber 21 in the barrel 13 and the third extrusion sleeve 15 is respectively connected to the first feed port 12, the second feed port 14 and the third feed port 16, and the melting extrusion device includes a first motor 22, and the first motor 22 is fixedly installed at one end extending from the melting chamber 21. The output end of the first motor 22 extends through the melting chamber 21 and is fixedly connected to the pushing screw 23. A plurality of stirring screws 24 are installed in the middle of the pushing screw 23. A plurality of electric heating plates 25 are installed on the outer wall of the melting chamber 21 located in the first extrusion sleeve 11, the second extrusion sleeve 13 or the third extrusion sleeve 15.

[0049] In the above embodiment, it should be noted that the melt extrusion devices in the first extrusion sleeve 11, the second extrusion sleeve 13 and the third extrusion sleeve 15 have the same structure, but the temperature set by the electric heating plate 25 on the surface of the melting chamber 21 in each extrusion sleeve is different. The electric heating plate 25 in the first extrusion sleeve 11 is set to the highest temperature because it is necessary to quickly and completely soften the polyester material and the antibacterial agent and cooperate with the diverter 17 and the drawing plate 18 to extrude the inner core of the antibacterial polyester yarn; the electric heating plate 25 in the second extrusion sleeve 13 is set to a lower temperature than the electric heating plate 25 in the first extrusion sleeve 11, because the second layer of polyester material extruded on the surface of the inner core of the polyester yarn is thinner than the inner core, so the time to soften at the same temperature is shorter. Similarly, under the same softening time, setting a lower temperature can make the polyester material in the melting chamber 21 in the second extrusion sleeve 13 and the melting chamber in the first extrusion sleeve 11 21 is softened at the same time; the set temperature of the electric heating plate 25 in the third extrusion sleeve 15 is lower than the temperature of the electric heating plate 25 in the second extrusion sleeve 13, because the time when the polyester yarn reaches the third-level extrusion base 36 is later than the time when it reaches the secondary extrusion base 34, the polyester material in the melting chamber 21 in the third extrusion sleeve 15 can be heated for a longer time than the polyester material in the melting chamber 21 in the second extrusion sleeve 13. In order to achieve simultaneous softening of the polyester materials, it is necessary to lower the temperature of the electric heating plate 25 in the third extrusion sleeve 15; in summary, the temperature of the electric heating plate 25 in the first extrusion sleeve 11, the second extrusion sleeve 13 and the third extrusion sleeve 15 decreases, and the loss degree of the antibacterial agent in each layer of polyester material is also reduced successively, so as to achieve the effect of reducing the loss of the antibacterial agent under the premise of smooth extrusion molding of the antibacterial polyester yarn, and reduce the volatilization or thermal degradation of the antibacterial agent;

[0050] The polyester material and the antibacterial agent are heated and melted by starting the electric heating plate 25 in the corresponding extrusion sleeve, and the corresponding first motor 22 is started to drive the pushing screw 23 and the stirring screw 24 to evenly mix the polyester material and the antibacterial agent, so as to achieve the effect of heating and melting the polyester material and the antibacterial agent and mixing them evenly, and finally extruding them from the corresponding melting chamber 21.

One end of the extrusion groove 37 on the secondary extrusion base 34 is connected to the melting cabin 21 in the second extrusion sleeve 13, and one end of the extrusion groove 37 on the tertiary extrusion base 36 is connected to the third The melting chamber 21 in the extrusion sleeve 15 is connected, and the coating structure includes a filament upper closing plate 40, which is embedded in the secondary extrusion flap 33 or the tertiary extrusion flap 35 on the side of the extrusion groove 37 close to the primary wire drawing chamber 31, and a coarse filament upper closing plate 42 is installed on the side of the extrusion groove 37 in the secondary extrusion flap 33 or the tertiary extrusion flap 35 away from the filament upper closing plate 40, a filament lower closing plate 41 is installed on the side of the extrusion groove 37 in the secondary extrusion base 34 or the tertiary extrusion base 36 close to the primary wire drawing chamber 31, and a coarse filament lower closing plate 43 is installed on the side of the extrusion groove 37 in the secondary extrusion base 34 or the tertiary extrusion base 36 away from the filament lower closing plate 41.

[0052] In the above embodiment, it should be noted that, driven by the upper line device, the inner core of the polyester filament extruded from the wire drawing plate 18 will sequentially pass through the primary wire drawing chamber 31, the secondary extrusion base 34, the secondary wire drawing chamber 32 and the tertiary extrusion base 36 and extend to the twisted wire turntable 2. When passing through the secondary extrusion base 34 and the tertiary extrusion base 36, the polyester filament will first enter the thin filament lower clamping plate 40 and then enter the coarse filament lower clamping plate 43. The inner diameter of the thin filament lower clamping plate 40 is equal to the diameter of the polyester filament after being thinned by the wire drawing shaping structure, and the inner diameter of the coarse filament lower clamping plate 43 is equal to the diameter of the polyester filament after being extruded by the coating structure. By rotating the secondary extrusion flap 33 and the tertiary extrusion flap 35, the filament upper closing plate 40 is driven to be spliced ​​with the filament lower closing plate 40, and at the same time, the filament lower closing plate 40 is spliced ​​with the coarse filament lower closing plate 43, as the polyester material in the melting chamber 21 in the second extrusion sleeve 13 is squeezed into the secondary extrusion flap 33 and the extrusion groove 37 on the secondary extrusion base 34, and the polyester material in the melting chamber 21 in the third extrusion sleeve 15 is squeezed into the tertiary extrusion flap 35 and the extrusion groove 37 on the tertiary extrusion base 36, so as to achieve the effect of wrapping the passing polyester filaments with the second and third layers of polyester material.
