Description

Technical Field

[0002] Chemical fiber is a by-product of the modern petroleum industry. It is widely used in the textile industry and processed into daily textile items such as clothing, tents, ropes, etc. The more mainstream chemical fibers include polyester, nylon and other products. The diameter of chemical fiber ranges from a few microns to hundreds of microns, and it is woven into yarn according to the application, and then the yarn is woven into cloth; or blended with cotton yarn to form cloth, etc. The electrical, physical and chemical properties of chemical fiber fabrics are determined by the properties of chemical fiber and reflected by the macroscopic properties of chemical fiber microscopic properties. In today's chemical and textile industries, chemical bleaching and printing are the basic methods to change the color and finished product characteristics of chemical fiber at the microscopic and macroscopic levels. The advantages of these processes are low equipment and process investment costs, but the disadvantage is that the coating is too thick, ranging from a few microns to tens of microns, which is at the same order of magnitude as the diameter of the chemical fiber. Therefore, it is inevitable to cause changes in the mechanical properties of chemical fiber, making chemical fiber yarns not soft, light-proof, and heat-proof, and unable to meet the needs of high-end applications. In addition, many new materials such as silicon, tin oxide, diamond-like carbon coating (DLC), silicon nitride, titanium nitride and other new materials cannot be printed on Katao fibers through chemical dyeing or printing technology.

[0003] Therefore, it is urgent to provide a device that can cover chemical fiber yarn with an ultra-thin film layer so that the physical and chemical properties of the chemical fiber yarn can be increased with new functions while maintaining the original mechanical properties.

[0030] Combination Figure 1 and Figure 2 As shown, before the implementation of the utility model, the thread ends of the chemical fiber yarn 100 on the unwinding wheel 10 are firstly wound around the first tension wheel 20 of the first tension chamber 2 in sequence, and then enter the deposition chamber 3 through the first channel 60 and pass through the deposition device 30, and then enter the second tension chamber 4 through the second channel 70 and are sequentially wound around the second tension wheel 40, and finally enter the winding chamber 5 and fix the thread ends of the chemical fiber yarn 100 on the winding wheel 50, so as to realize the penetration of the entire line of the chemical fiber yarn, thereby ensuring that during implementation, the chemical fiber yarn 100 unwound from the unwinding wheel 10 can be completely wound around the winding wheel 50 after coating. On the premise that the ends of the chemical fiber yarns are fixed on the winding wheel 50, when the utility model is implemented, since the unwinding wheel 10 and the winding wheel 50 have the same structure and rotate synchronously, the chemical fiber yarn 100 unwound on the unwinding wheel 10 is adjusted by the tension of the first tension wheel 20 before coating and the second tension wheel 40 after coating, so that the chemical fiber yarn 100 is always kept taut during the entire transmission process, ensuring that the chemical fiber yarn 100 can pass through the deposition device 30 in the deposition chamber 3 at a uniform speed and be deposited and coated with a uniform film layer in the deposition device 30, thereby completing the coating of the chemical fiber yarn; the coated chemical fiber yarn 100a is orderly wound on the winding wheel 50; specifically, Figure 1 As an example of the embodiment shown in the figure, the unwinding wheel 10 of the utility model is along Figure 1 The chemical fiber yarn 100 is unwound in the direction of the arrow A, and the winding wheel 50 is moved along Figure 1The coated chemical fiber yarn 100a is wound in the direction of the arrow B. The chemical fiber yarn coating equipment of the utility model is specially used for coating chemical fiber yarn with an ultra-thin film layer, and the thickness of the film layer is nanometer level. The size and specification of the chemical fiber yarn after coating are basically the same as the size and specification of the chemical fiber yarn before coating, so that the physical and chemical properties of the chemical fiber yarn after coating are maintained while maintaining the original mechanical properties, and also increase the new functions corresponding to the film layer material.

[0031] like Figure 1 and Figure 2 As shown, in order to improve the coating quality and effect of the chemical fiber yarn 100. The deposition device 30 of the chemical fiber yarn coating equipment of the utility model is a structure for generating plasma enhanced chemical vapor deposition. Specifically, the deposition device 30 is suspended in the deposition chamber 3; the deposition device 30 is suspended in the deposition chamber 3, which can effectively lay out the deposition device 30 as a device for generating plasma enhanced chemical vapor deposition.

[0032] Further, if Figure 1 and Figure 2As shown, the deposition device 30 of the present invention comprises an electrode plate 31, a gas distribution box 32 for releasing ionized gas onto the chemical fiber yarn 100, an insulating enclosure 33, an insulating suspension member 34 and a power supply 35. The gas distribution box 32 of the present invention is a conductive hollow structure, and the hollow structure forms a deposition chamber 36. The left wall of the gas distribution box 32 of the present invention is provided with an entrance 321 facing the first channel 60, and the right wall of the gas distribution box 32 is provided with an exit 322 facing the second channel 70; the gas distribution box 32 is parallel to and opposite to the electrode plate 31, and the electrode plate 31 is located directly above the gas distribution box 32. The insulating enclosure 33 of the present invention is arranged around the boundary between the electrode plate 31 and the top 32a of the gas distribution box 32, and the area between the electrode plate 31 and the top 32a of the gas distribution box 32 is enclosed by the insulating enclosure 33 to form a closed ionized glow area 37. The right side of the ionized glow region 37 of the utility model is provided with an air inlet 371 for gas to enter, and the left side of the ionized glow region 37 is provided with an air outlet 372 for ionized gas to enter the gas distribution box 32, and the gas distribution box 32 is connected to the ionized glow region 37 through the air outlet 372. The upper end of the insulating suspension member 34 of the utility model is connected to the top wall 3a of the deposition chamber 3, and the lower end of the insulating suspension member 34 is connected to the electrode plate 31, so that the deposition device 30 of the utility model is suspended in the deposition chamber 3 in an insulated manner from the deposition chamber 3 by the insulating suspension member 34. The two poles of the power supply 35 of the deposition device 30 of the utility model are electrically connected to the electrode plate 31 and the gas distribution box 31 respectively. The utility model forms a closed and insulated ionization glow zone 37 through the electrode plate 31, the top 32a of the gas distribution box 32 and the insulating enclosure 33. The electrode plate 31 and the gas distribution box 32 are electrically connected to the two poles of the power supply respectively, so that an electric field is formed between the electrode plate 31 and the top 32a of the gas distribution box 32. The electric field vertically runs through the entire ionization glow zone 37; the air inlet 371 on the right side of the ionization glow zone 37 is connected to the electric field 37a of the gas distribution box 32. Figure 2 After the gas is introduced into the ionization glow region 37 in the direction of arrow C shown in FIG. 1 , the gas is ionized under the action of the electric field, and the ionized gas passes through the gas outlet 372 on the left side of the ionization glow region 37 along the Figure 2The gas enters the deposition chamber 36 of the gas distribution box 32 in the direction of the arrow D shown. The ionized gas entering the deposition chamber 36 of the gas distribution box 32 is deposited on the chemical fiber yarn 100 entering the deposition chamber 36 from the inlet 321. The chemical fiber yarn 100 entering the deposition chamber 36 moves toward the winding wheel 50 while being deposited and coated in the deposition chamber 36. The coated chemical fiber yarn 100a is output from the outlet 322 and leaves the deposition chamber 36 to complete the coating. The coated chemical fiber yarn 100a then enters the second tension wheel 40 of the second tension chamber 4 from the second channel 70, and is finally wound on the winding wheel 50 of the winding chamber 5. As can be seen from the above, the utility model sets up an ionization glow zone 37 and a deposition chamber 36 that are interconnected and independent, so that the ionization glow zone 37 only ionizes the gas; the ionized gas enters the deposition chamber 36 of the gas distribution box 32, and the ionized gas is buffered in the deposition chamber 36 of the gas distribution box 32, so that the ionized gas is distributed more evenly in the deposition chamber 36, so that the density and speed of the ionized gas in the deposition chamber 36 of the gas distribution box 32 are relatively consistent, ensuring the consistency of the coating of the ionized gas deposited on the chemical fiber yarn 100, so that the ionization and deposition of the utility model are completed in independent areas respectively, effectively avoiding the occurrence of technical problems of plasma attacking the surface of the deposited film, and substantially solving the technical problem of the deposited film being attacked and causing serious defects caused by the simultaneous ionization and deposition of gas in the ionization glow zone in the prior art, ensuring the stability of the nano-scale film layer formed by coating on the micron-scale chemical fiber yarn 100. At the same time, since the ionization glow zone 37 of the utility model is only used for gas ionization, and the gas distribution box 32 is only used for transmitting and releasing ionized gas and for the passage of the chemical fiber yarn 100, this indirect PECVD deposition method makes the utility model more sufficient for gas ionization and the film deposited on the chemical fiber yarn 100 is more uniform, which not only makes full use of the ionized gas, but also ensures the uniformity of the deposited film, greatly improves the quality of the deposited film, and further makes the physical and chemical properties of the chemical fiber yarn 100a after coating maintain the original mechanical properties while increasing the new functions corresponding to the film material, which is highly practical and suitable for wide promotion and use.

[0033] like Figure 1 and Figure 2 As shown, preferably, the first channel 60, the inlet 321, the outlet 322 and the second channel 70 of the chemical fiber yarn coating device of the present invention are located on the same horizontal line. The chemical fiber yarn 100 is effectively passed horizontally in the deposition chamber 36 and coated, further ensuring the uniformity and consistency of the deposition coating of the chemical fiber yarn 100 in the deposition chamber 36.

The first tension wheel 20 and the second tension wheel 40 have the same structure and the layout is symmetrically arranged with respect to the deposition chamber 3, which effectively ensures that the speed of the chemical fiber yarn 100 from unwinding to winding is consistent during the entire transmission process, and ensures that the chemical fiber yarn 100 will not be knotted; on the other hand, it is also convenient for manufacturing and installation, saving costs.

[0035] like Figure 1 As shown, preferably, the unwinding chamber 1 of the chemical fiber yarn coating device of the utility model is further provided with a first driven wheel 10a, and the chemical fiber yarn 100 unwound by the unwinding wheel 10 is wound around the first driven wheel 10a and then enters the first tension chamber 2 through the first channel 60. The setting of the first driven wheel 10a effectively adjusts the angle between the unwinding wheel 10 and the first tension wheel 20, so that the chemical fiber yarn 100 can be horizontally transported to the first tension wheel 20; at the same time, it also plays a role in adjusting the tension of the chemical fiber yarn 100 transmitted between the unwinding wheel 10 and the first tension wheel 20, so that the chemical fiber yarn 100 is always kept taut.

[0036] like Figure 1 As shown, preferably, the winding chamber 50 of the chemical fiber yarn coating device of the utility model is further provided with a second driven wheel 50a, and the coated chemical fiber yarn 100a output from the second channel 70 is wound around the second driven wheel 50a and then wound around the winding wheel 50. The setting of the second driven wheel 50a effectively adjusts the angle between the second tension wheel 40 and the winding wheel 50, so that the coated chemical fiber yarn 100a can be horizontally transported from the second tension chamber 4 to the winding chamber 5; at the same time, it also plays a role in adjusting the tension of the coated chemical fiber yarn 100a transmitted between the second tension wheel 40 and the winding wheel 50, so that the chemical fiber yarn 100a is always kept taut.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
