The present invention relates to a textile processing needle. BACKGROUND ART In the process of manufacturing felt fabrics, nonwoven fabrics, sewn products, knitted products, etc. of chemical fibers and natural fibers, there is a step of processing fibers using punching needles, sewing needles, stockinette needles (knitting needles), etc. The needles used in these processes have recently become faster and more diverse and sophisticated in order to improve productivity, and as a result, the parts of the needle that rub against the fibers have become more abrasive. Increasingly, defects occur that reduce the commercial value of needles, or needles no longer function as intended. This necessitates repeated early replacement of needles, resulting in significant productivity and economic losses. Conventionally, this type of needle was JISG3502 (piano wire)
After applying appropriate hardness (Hv600 to 700) and toughness through heat treatment (quenching, tempering) using SK-4 polished steel as specified in SWRS87 or JISG4401 (carbon tool steel) as the material, Normally used. However, as a countermeasure in the case of low wear resistance, we usually use (1) a higher grade steel with alloying elements (for example, JIS G4403 SKH-9 or
Change the material to JISG4404 SKS-2). or (2) hard Cr in the friction part with the fibers of these needles.
It is conceivable to process plating or electroless plating of Ni--P (commonly called Kanizen plating), but none of these methods can be realized for the following reasons. In other words, (1) is because when conventional dies and jigs used for cold forming needles are used for forming needles using high-grade materials with added alloying elements, wear and tear on the dies and jigs is significantly accelerated. The production efficiency and yield of the needles are very low, and the cost of the needles is too high to be practical. In method (2), the important parts of these needles are generally fine and precise, so it is very difficult to plate them uniformly.
It was found that there were some areas where the plating was prone to peeling off, and this did not improve the situation. The object of the present invention is basically to improve these drawbacks and provide a fiber processing needle that has durable wear resistance and excellent fiber processing performance. Other objects of the invention will become clear from the further description below. The present invention aims to achieve such an object, and is characterized in that a coating of a superhard material is formed by ion plating to a thickness of 3 to 10 microns on at least the frictional part of the needle with the fibers. This is a needle for textile processing. That is, the present invention provides TiC (titanium carbide), TiN ( titanium nitride), CrN (chromium nitride), Al 2 O 3 (aluminum oxide), TiO 2 (titanium oxide), V (vanadium carbide), NbC (neobium carbide), Mo 2 C (molybdenum carbide), and
The needles are coated with a super-hard material such as VN (vanadium nitride) to a thickness of 3 to 10 μm (microns) with high adhesion to provide exceptionally high abrasion resistance. The present invention will be specifically explained below. In the present invention, the frictional part with the fiber is usually the tip of the needle. FIG. 1 is a perspective view of a needle that punches a fibrous nonwoven web or the like to entangle the fibers. There is a friction part 2 at the tip of the needle 1 that makes contact with the fibers, and there is a barb 3 that attracts the fibers. FIG. 2 is an enlarged view of the barb 3 in FIG. 1. If the barb 3 portion is worn out due to the use of the needle, the function of intertwining fibers and increasing felt density during the punching process can be maintained, and the function of producing felt fabric or nonwoven fabric is lost. Further, FIG. 3 is a partial side view of the sewing machine needle, and there is a friction part 2 with the fibers at the pointed part. This pointed portion bends and deforms when the needle generates frictional heat during high-speed sewing, or when it reaches the softening or melting point of the fiber, skipped stitches or thread breakage occur, making it impossible to sew. FIG. 4 is a partial view showing the state of a conventional needle after use. FIG. 5 is a perspective view of a stockinette needle. Here, the hook portion 4 has a friction portion with the fibers.
When the fibers are rubbed against the hook portion 4 and worn, single thread breakage of the fibers occurs, and the knitting function cannot be achieved. Next, the principles and features of the ion plating process applied to the present invention will be explained. This method is usually a method in which argon is deposited on a substrate (material to be ion-plated) to which a negative voltage is applied in a glow discharge. Vapor deposition progresses while the substrate is constantly sputter etched by bombardment of ion plating atoms that evaporate argon that is ionized and accelerated during the discharge. As a result, the temperature of the substrate rises, and the deposition progresses while the surface is continually cleaned. As a result, a film with high adhesion and few pinholes can be obtained. Reactive ion plating is a process in which a gas that reacts with the evaporated metal to form a compound is introduced instead of argon gas or into a part of the ion plating process, and is also applied to the present invention. There are other methods of coating steel with superhard materials other than these ion plating treatments. For example, (1)
Thermal spraying has been around for a long time, but it is not suitable for coating the minute parts of this type of needle. In addition, (2) various chemical vapor deposition methods have recently been developed, but since the processing temperature of this method is generally as high as 900°C or higher, the steel material to be treated becomes significantly softened at this temperature, making it difficult to put into practical use. It will no longer be available. In the ion plating treatment, it is sufficient to raise the temperature of the substrate to 450 to 520° C. during the treatment in order to increase the adhesion between the substrate and the coating superhard material, and appropriate strength and toughness can be maintained. Next, an explanation will be given of an example of TiC plating of the punching needle, sewing needle, and stockinette needle according to the present invention, and the effects obtained when these needles are used. First, after degreasing the punching needles, knitting needles, and sewing machine needles of the material to be treated with ether, etc., the main important part of each needle is as parallel as possible to the hearth in which the evaporated substance, such as metal, is placed, and the needles are parallel to the material to be treated. Place it in a vacuum container so that the distance from the hearth is 15 to 20 cm, and clean the surface of the substrate (material to be treated, in this case the needle).
After evacuating the vacuum container to a vacuum level of 10 -4 Torr or less, high-purity argon gas is introduced at a vacuum level of 10 -2 to 10 -3 Torr, and a DC voltage of - is applied between the evaporation source and the substrate.
The surface of the substrate was cleaned by applying 3 Kv and sputtering argon onto the substrate for about 10 to 30 minutes. After this, approximately
Ti was melted and evaporated for 7 to 15 minutes under the conditions of 10Kv x 300mA, and C2H5 was evaporated 5x as a reaction gas.
Only a flow rate that is balanced at 10 -4 Torr pressure is introduced into the system, and TiC is plated by the reaction of 2Ti (gas) + C 2 H 2 (gas) → TiC (solid) + H 2 (gas). During this plating, the substrate is plated with TiC to ensure strong adhesion.
Heat to 450-520℃. However, with this installation method, when the metal inside the hearth melts and evaporates, it evaporates straight in one direction, so the shadowed areas that are poorly covered will not be plated. Therefore, the position and direction of the needle should be set optimally. Furthermore, if the ion plating cannot be performed completely in one go, the following procedure may be performed. for example,
In the first ion plating treatment of the punching needle, as illustrated in Figure 6A, the shaded area (barb 3) is not plated in the ion plating treatment direction indicated by the arrow, so the wear resistance will not improve much if left as is. It will no longer be done. In this case, by changing the mounting direction of the object to be processed two or more times depending on the type of needle during the ion plating process, the coating 5 can be sufficiently formed in the required area. For example, a punching needle undergoes the first processing shown in FIG. 6A, the second processing shown in FIG. 6B, and then the third processing shown in FIG. 6C. As for the sewing machine needle, as shown in FIG. 7, attach the point of the needle on the lower side perpendicular to the hearth. As for the stockinette needle, as shown in Fig. 8A, the straight direction of the evaporated metal (arrow) and approximately 45
After processing one side while holding the substrate at an angle of 100 degrees, the back side is subjected to ion plating treatment as illustrated in FIG. 8B. Note that heating this substrate to 450 to 520° C. softens the substrate. Needles used in the production of varieties where this softening is particularly problematic are treated with the well-known ion nitriding or salt bath soft nitriding process (commonly referred to as tuftriding) before being ion plated. If the nitrided part is heated and nitrided, the nitrided part will not soften, thereby preventing problems such as a decrease in the bending strength of the needle, or 800 After heating at ~820℃, oil quenching and then 150℃
High hardness and toughness can be restored by tempering at 200°C. The table below shows the Hv hardness before and after applying TiC plating to punching needles, sewing needles, and stockinette needles as ion plating (IP).

[Table] In addition, it is not economical because it requires complex and expensive equipment investment to operate in a relatively high-vacuum system at a limited location, but it is possible to perform ion plating treatment even in shadow areas with poor circulation. When performing the treatment, the object to be treated may be rotated. According to the present invention, by forming a film of such a superhard material, there is less friction against fibers and the needle is durable, so that the number of times the needle needs to be replaced can be reduced. In addition, since the coefficient of friction is reduced, there are fewer fibers and threads cut, and work efficiency is improved, resulting in products with stable quality. Furthermore, the needles could get rusty due to the oils attached to the fibers, and there were restrictions on the oils that could be used.However, since the needles of the present invention have good corrosion resistance, there are fewer restrictions on the oils that can be used, and the quality of the product can be improved. It has the advantage of being able to choose the oil. In addition, ion plating has the advantage of higher processing accuracy than plating, is easy to adhere to even if it is very thin, does not rust, and has good sliding properties. Example 1 A fiber web for non-woven fabric was prepared using a 3D (denier) 51 mm polyester fiber by a conventional method and needle punched to compare the wear condition between the product of the present invention and a conventional punching needle. The product of the present invention was processed as shown in (b) of Table 1 above, and the conventional product was processed as shown in (a) of Table 1.
All of them were quenched in oil at 790-830℃ and tempered at 180-220℃. Punching needles are installed in the production machine for each test needle, with a web weight of 470 g/m 2 and a punch stroke.
After 200 days of continuous use at 500 rpm and 3.8 mm pitch, the needle was removed and the wear condition was investigated.
The barb part of the conventional product was worn to the point where it became rounded, but the product of the present invention showed no damage and was confirmed to be able to be used for a long period of time. Example 2 The usual sewing conditions for polyester-cotton blend work clothes were to use a No. 16 sewing machine needle, stack 4 pieces,
When sewing at a sewing machine speed of 5,000 stitches/min and a stitch size of 13 stitches/cm, when using the conventional needle shown in Table 1 (a), the pointed head of the needle bends and deforms as shown in Figure 4. Because of this, I had to replace the sewing machine needle with a new one after two days of use. The needle shown in Table 1 (b) of the present invention can extend its life by three times even under the same usage conditions as conventional products. Example 3 As a “matting” agent using a regular warp knitting machine
Polyester fiber [30D denier) 10 filaments] with 0.25% TiO 2 added is knitted, and the knitting structure is half, 34 gauge (number of needles per inch), 72
When manufactured under normal conditions of course/inch and 700 courses/min, conventional products in Table 1 (a) and Table 1 (b)
After incorporating this invention into a production machine and using it for 100 days, the wear condition was examined using a scanning electron microscope.
Due to scratches caused by fiber friction on the hook part of the conventional product, we were forced to replace it with a new needle.
The product of the present invention suffered no damage and could be used continuously. Here, the term "course" refers to the number of stitches/inch in the vertical direction.
