Description
Technical Field
The present invention relates to a metal slide fastener. More specifically, the present invention relates to a fastener element tape provided with a metal element, a fastener chain, and a method for manufacturing the fastener chain.
Background
Slide fasteners are often used as openers and closers in daily necessities such as clothing, bags, shoes, and miscellaneous goods, and industrial goods such as tents. In general, a slide fastener is mainly composed of three portions, i.e., a pair of fastener tapes, a plurality of elements as engaging portions of the slide fastener fixed along one side edge of each tape, and a slider for controlling opening and closing of the slide fastener by engaging and separating the elements. A fastener tape is formed by attaching a plurality of elements along one side edge of a fastener tape, and a fastener chain is formed by coupling a pair of right and left elements by engagement of the elements. Then, if a slider and, if necessary, a stopper are attached to the fastener chain, a slide fastener is produced.
A metal slide fastener using a metal fastener element is known as a slide fastener. Conventionally, as a material of a metallic element, a copper alloy such as copper-zinc alloy such as bronze or brass, or copper-zinc-nickel alloy such as zinc white copper, and in addition, an aluminum alloy has been mainly used. These alloys can provide various hues such as bronze, golden, silver, etc., depending on the composition of the material used.
For example, japanese patent No. 4357869 (patent document 1) discloses a Cu — Zn alloy for a slide fastener, which can be cold worked in a Cu alloy containing zinc at a high concentration and has high strength and excellent durability and cracking resistance. This publication describes that the long-life cracking resistance is improved by reducing the tensile residual stress or performing a treatment to a state of compressive residual stress on the surface of the Cu — Zn alloy. As a method of reducing the tensile residual stress, there are described surface hardening methods such as shot peening (shot peening), shot blast (shot blast), sand blast (sand blast), and steel shot peening, in which surface hardening is caused by continuously applying an impact to the surface of a material.
Jp 2004-250760 a (patent document 2) discloses an Al — Mg-Mn-Cr alloy for slide fasteners having a predetermined composition, which has mechanical properties such as strength and hardness, and is excellent in metallic luster and decorativeness.

Problems to be solved by the invention
The appearance of the metal surface changes not only in accordance with the color tone but also in accordance with the sense factors characterizing the surface of the object, i.e., the sense of unevenness, the sense of luster, the sense of transparency, the sense of depth, the texture, and the like. These are called surface properties (texture) as visual perception attributes related to the surface of an object due to the material or surface structure, and give the material an inherent texture. In recent years, a slide fastener is required to have appearance according to its use, and it is required to provide elements having various textures.
However, in the prior art, emphasis is placed on the appearance based on color tone, and the appearance based on texture is not sufficiently considered. It is contemplated that some surface treatment may be applied to the metal surface to cause a change in texture. As a method of surface treatment, dry blasting such as shot peening, shot blasting, sand blasting, and steel shot blasting as described in patent document 1, and etching treatment by chemicals, buffing, and the like are considered. However, when such surface treatment is applied to a fastener tape or a fastener chain, the fastener tape is discolored, contaminated, or damaged.
In many cases, metallic fastener elements are produced by rolling and wire drawing, and these plastic-worked articles have a longitudinal stripe pattern on the surface. These streaks cause a reduction in the appearance, and therefore, it is desired to perform a sufficient surface treatment to the extent that the streaks can be eliminated.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a fastener tape or a fastener chain in which the texture of a metal element is changed to such an extent that a stripe pattern is eliminated while discoloration, contamination, and damage of the fastener tape are suppressed.

Detailed Description
(1. zipper chain tooth belt, zipper chain and zipper)
One embodiment of the present invention is a fastener element tape including a fastener tape and a plurality of elements fixed along one longitudinal edge of the fastener tape. Another embodiment of the present invention is a fastener chain including the fastener tape. Typically, a fastener chain is formed by engaging a plurality of elements of a pair of fastener element tapes with each other. In addition, another embodiment of the present invention is a slide fastener including the fastener tape or the fastener chain. The slide fastener is manufactured by attaching a slider to a fastener chain and attaching a stopper as needed.
Fig. 1 is a schematic plan view of one main surface of a slide fastener according to an embodiment of the present invention when the main surface is viewed from a direction perpendicular to the main surface. As shown in fig. 1, the slide fastener includes: a pair of fastener tapes 1 each having a core portion 2 formed on one end side; a plurality of elements 3 which are fixed (attached) to the core portion 2 of the fastener tape 1 by being pressed (japanese: かしめ) at predetermined intervals; an upper stopper 4 and a lower stopper 5 which are fixed by being pressed against the core portion 2 of the fastener tape 1 at the upper and lower ends of the plurality of elements 3; and a slider 6 which is slidably moved in the vertical direction, is disposed between the pair of elements 3 facing each other, and engages and disengages the pair of elements 3. The lower stopper 5 may be a separable bottom end stop including an insert pin, a box pin, and a box body, and may be configured to be capable of separating the pair of fastener tapes by a separating operation of the slider.
Fig. 2 is a view showing a method of manufacturing the fastener element 3, the upper stopper 4, and the lower stopper 5 of the slide fastener shown in fig. 1, and a mode of attachment to the core portion 2 of the fastener tape 1. As shown, the coupling element 3 is mounted by: the deformed line 8 having a substantially Y-shaped cross section, which is produced through the heat treatment and cold rolling steps, is cut into a predetermined size and is press-formed, whereby a convex portion and a concave portion for engagement are formed in the head portion 9, and then both the leg portions 10 are pressed against the core portion 2 of the fastener tape 1.
The upper stop 4 is mounted by: a rectangular wire 11 (flat wire) having a rectangular cross section is cut into a predetermined size, is formed into a shape having a substantially japanese katakana "コ" cross section by bending, and is then pressed against the core portion 2 of the fastener tape 1. The lower stop 5 is mounted by: the special-shaped thread 12 having a substantially X-shaped cross section is cut into a predetermined size and then pressed against the core portion 2 of the fastener tape 1.
In the drawings, the fastener elements 3, the upper stop 4, and the lower stop 5 are attached to the fastener tape 1 at the same time, but actually, the fastener elements 3 are attached to the fastener tape 1 intermittently for every predetermined region, a fastener chain is first produced, and the predetermined upper stop 4 or lower stop 5 is attached to a region of the fastener chain where no fastener element is attached.
The slide fastener can be fixed to various articles, and particularly functions as an opening/closing tool. The article to which the zipper is fixed is not particularly limited, and examples thereof include daily necessities such as clothing, bags, shoes, and miscellaneous goods, and industrial goods such as water tanks, fishing nets, and space suits.
In one embodiment of the fastener tape or the fastener chain of the present invention, the fastener tape and the plurality of elements are wet-blasted. Wet blasting is a method of ejecting a slurry containing a medium (solid particles) and water from an ejection nozzle at a high speed by the force of a compressed gas. The medium collides with the element surface, so that the texture of the element surface can be changed and the stripe pattern can be eliminated. In the wet blasting, the unique unevenness can be grown on the surface of the fastener element by causing the medium to collide with the fastener element, and a texture which is difficult to develop in liquid phase treatment or gas phase treatment such as chemical etching or chemical conversion treatment can be obtained.
The texture of the fastener element surface can be changed by the dry blasting and the stripe pattern can be eliminated to obtain a texture similar to that of the wet blasting, but the wet blasting provides advantages as shown below compared with the dry blasting.
(1) Damage to the fastener tape and discoloration caused thereby can be suppressed.
(2) Since the wet shot sprays the medium together with water, no dust is generated, and contamination of the fastener elements or fastener tapes can be suppressed.
(3) No dust is generated, so that the working environment is good.
(3) Since the sprayed water functions as washing water, the medium is less likely to remain on the fastener tape.
(4) Water produces a cooling effect and thus does not generate processing heat. Therefore, the metallic structure of the fastener element is prevented from being changed by heating.
(5) Static electricity is not generated, so that the safety is high.
Thus, according to the wet shot, the texture of the metal fastener elements can be changed to such an extent that the stripe pattern disappears while suppressing discoloration, contamination, and damage of the fastener tape, and the condition of the fastener tape after wet shot differs from the condition of the fastener tape after dry shot, but it is difficult to express the condition quantitatively. Even if quantitative representation is possible, much labor and time are required to establish the analysis method. Therefore, in the present invention, the article obtained by dry-blowing is distinguished from the article obtained by wet-blowing by the description of the manufacturing method of "the fastener tape and the plurality of fastener elements are wet-blown".
According to the results of the study by the present inventors, regarding the surface properties of the fastener elements after wet shot blasting, when the surface roughness represented by the arithmetic mean height (Sa) and the skewness (Ssk) and the line roughness represented by the arithmetic mean roughness (Ra) satisfy the following conditions, it is possible to simultaneously realize the suppression of the damage of the fastener tape and the texture change to the extent that the stripe pattern disappears.
(1) The surface roughness of the center of the leg portion, which is visible when the main surface is viewed from the direction perpendicular to the main surface on at least one side of the fastener tape or the fastener chain, satisfies 2 [ mu ] m & lt Sa & lt 8 [ mu ] m and 0 & lt Ssk, and preferably further satisfies 0.1 & lt Str & lt 0.7 for each element.
(2) In each fastener element, as for the line roughness of the center of the leg portion visible when the main surface of at least one side of the fastener element tape or the fastener chain is observed from the direction perpendicular to the main surface, the line roughness is based on the arithmetic curve of the roughness curve in the direction parallel to the longitudinal direction of the fastener tape (the direction of arrow a in fig. 1)Average roughness (Ra)1) Is set as AveRa1(μm) the arithmetic average roughness (Ra) based on the roughness curve in the direction perpendicular to the longitudinal direction of the fastener tape (the direction of arrow B in FIG. 1)2) Is set as AveRa2(mum), satisfies 0 ≦ AveRa1-AveRa2|/(AveRa1And AveRa2Any one of the larger) is less than or equal to 0.35.
In the present invention, Sa, Str, and Ssk are measured by a noncontact surface roughness meter in accordance with international organization for standardization ISO 25178. The measurement of Sa, Str, and Ssk of each element was performed with the range of 500 μm × 1000 μm of the center of the leg portion of the element visible from the observation direction as the measurement range (see fig. 3). The length of 500 μm of the observation field is taken from a direction parallel to the longitudinal direction of the fastener tape (the direction of arrow a in fig. 1), and the length of 1000 μm of the observation field is taken from a direction perpendicular to the longitudinal direction of the fastener tape (the direction of arrow B in fig. 1). The boundary between the head portion and the leg portion in the direction perpendicular to the longitudinal direction of the fastener tape is the root portion on the leg portion side of the convex portion visible when viewed from the viewing direction.
In the present invention, Ra is a value according to japanese industrial standard JIS B0601: 2001, and measured by a noncontact surface roughness meter. AveRa of each element is obtained from 10 or more roughness curves in the direction parallel to the longitudinal direction of the fastener tape in the range of 500 μm × 1000 μm (the same as the measurement ranges of Sa, Str, and Ssk) of the center of the leg portion of the element visible when viewed from the observation direction1. Similarly, AveRa of each element is obtained from 10 or more roughness curves in the direction perpendicular to the longitudinal direction of the fastener tape in the range of 500 μm × 1000 μm (the same as the measurement ranges of Sa, Str, and Ssk) of the center of the leg portion of the element visible when viewed from the observation direction2. In the measurement of AveRa1And AveRa2In any of the cases, 10 or more roughness curves were obtained without omission so as to cover the entire center of the leg portion of the visible fastener element.
From the viewpoint of imparting a deep feel to the texture of the tooth, Sa is preferably 2 μm or more, more preferably 3 μm or more, and even more preferably 4.5 μm or more. While Sa can be increased by increasing the pressure of the compressed gas that humidifies the sprayed pellets and extending the spraying time, if Sa is made too large, damage to the fastener tape cannot be ignored, and the sliding resistance also increases. Therefore, Sa is preferably 8 μm or less, more preferably 7 μm or less, still more preferably 6.5 μm or less, and still more preferably 6 μm or less.
From the viewpoint of isotropy of appearance, Str is preferably 0.1 or more, more preferably 0.2 or more, and even more preferably 0.3 or more. From the viewpoint of isotropy of the surface roughness associated with uniformity of the appearance due to diffuse reflection of light, Str is preferably 0.7 or less, more preferably 0.6 or less, and even more preferably 0.5 or less.
When the pressure of the compressed gas for humidifying the shot is increased and the ejection time is prolonged, the Ssk tends to be small. If wet blasting is performed so strongly that Ssk shows a negative value, damage to the fastener tape cannot be ignored even if Sa has no problem. Therefore, the Ssk is preferably 0 or more, more preferably 0.1 or more, and still more preferably 0.3 or more. From the viewpoint of eliminating the stripe pattern on the element surface to improve the isotropy of the appearance, the Ssk is preferably 2.0 or less, more preferably 1.9 or less, and even more preferably 1.8 or less. When wet blasting is performed, Ssk tends to be smaller than that after rolling, and when conditions for wet blasting are alumina media with high cutting force, Ssk tends to be smaller.
Since the fastener elements after rolling have a striped pattern, the arithmetic average roughness (Ra) when measured based on a roughness curve in a direction parallel to the longitudinal direction of the fastener tape1) Arithmetic average roughness (Ra) measured based on roughness curve in the direction perpendicular to the longitudinal direction of the fastener tape2) The difference of (a) is large. Can be based on Ra1And Ra2The degree of disappearance of the fringe pattern was evaluated. According to the research results of the inventor, if AveRa1And AveRa2Is divided by AveRa1And AveRa2When the value obtained when any one of the values is larger (in the present invention, this value is referred to as "coefficient of variation in roughness") is 0.35 or less, the stripe pattern is less likely to be seen.
Thus, 0. ltoreq. AveRa is preferred1-AveRa2|/(AveRa1And AveRa2Any of the larger of (a) ≦ 0.35, more preferably 0 ≦ AveRa1-AveRa2|/(AveRa1And AveRa2Any of the larger of the above) 0.3 or less, and more preferably 0 or less | AveRa1-AveRa2|/(AveRa1And AveRa2Any of the larger of the above) 0.25 or less, and more preferably 0 or less | AveRa1-AveRa2|/(AveRa1And AveRa2Any larger of them) is less than or equal to 0.2.
AveRa is a measure for imparting depth to the texture of a tooth1Preferably 2 μm or more, more preferably 2.5 μm or more, and still more preferably 3.0 μm or more. In addition, AveRa from the viewpoint of the quality of the fastener chain1Preferably 9 μm or less, preferably 8.5 μm or less, more preferably 8.0 μm or less, and still more preferably 7.5 μm or less.
AveRa from the viewpoint of the change in appearance of the untreated article2Preferably 2.5 μm or more, more preferably 3.5 μm or more, and still more preferably 4.5 μm or more. In addition, AveRa from the viewpoint of the quality of the fastener chain2Preferably 10 μm or less, preferably 9.0 μm or less, more preferably 8.5 μm or less, and still more preferably 8.0 μm or less.
According to one embodiment of the present invention, each element visible when the main surface of at least one side of the fastener tape or the fastener chain is observed from a direction perpendicular to the main surface can satisfy the surface roughness (Sa, Str, and Ssk) and the line roughness (Ra)1、Ra2) The conditions of (1). According to a preferred embodiment of the present invention, each element visible when the both main surfaces of the fastener element tape or the fastener chain are observed from the direction perpendicular to the both main surfaces can satisfy the surface roughness (Sa, Str, and Ssk) and the line roughness (Ra)1、Ra2) The conditions of (1). I.e. self-bracing chainsWhen the fastener element tape or the fastener chain is observed in either direction of the front and back, each fastener element can satisfy the surface roughness (Sa, Str and Ssk) and the line roughness (Ra)1、Ra2) The conditions of (1).
The material of the fastener element is not particularly limited as long as it is made of metal, and for example, copper material, copper alloy material, aluminum alloy material, or the like can be used. Typical examples of the copper alloy material include copper alloys containing zinc (Cu — Zn alloys) such as bronze, brass, and zinc white copper. Typical examples of the aluminum alloy material include Al-Cu alloy, Al-Mn alloy, Al-Si alloy, Al-Mg-Si alloy, Al-Zn-Mg alloy, and Al-Zn-Mg-Cu alloy.
As the fastener tape, a fiber tape such as a woven fabric tape, a knitted fabric tape, or a nonwoven fabric tape, which has been used in a conventional slide fastener, can be used without particular limitation. As the material of the fiber, polyester, nylon, polypropylene, acrylic, and the like used in conventional slide fasteners can be used without particular limitation.
(2. production method)
The method of manufacturing the fastener stringer or the fastener chain of the present invention will be exemplified.
In one embodiment of the fastener stringer tape or the method for manufacturing a fastener chain of the present invention, the method includes:
a step of preparing a fastener element tape or a fastener chain provided with the fastener element tape, the fastener element tape including a fastener tape and a plurality of metal elements, each element having a pair of leg portions and a head portion connecting the pair of leg portions, the plurality of metal elements being fixed to one side edge of the fastener tape in a longitudinal direction thereof; and
and a wet shot blasting step of blasting a slurry containing water and a medium onto at least one main surface of the fastener tape or the fastener chain.
The fastener stringer before the wet blasting can be produced by any known method. For example, as described above, the present invention can be produced by: the fastener element is produced by cutting a profile line having a substantially Y-shaped cross section, which has been produced through a heat treatment and cold rolling process, into a predetermined size, and press-forming the profile line to form a convex portion and a concave portion for engagement at a head portion, and then, both leg portions of a plurality of fastener elements are pressed against a core portion of a fastener tape.
The wet spraying particles can be used for wet spraying particles on any one of the zipper tooth belt and the zipper chain. The wet blasting can be performed by spraying a slurry containing water and a medium onto at least one main surface of the fastener tape or the fastener chain. From the viewpoint of providing an appearance having a uniform feel on the front and back surfaces of the fastener chain tape and the fastener chain, it is preferable to apply wet blasting to the main surfaces on both sides.
The wet blasting is preferably performed under conditions satisfying the following (1) and (2).
(1) Each of the fastener elements after wet shot blasting satisfies 2 μm & lt Sa & lt 8 μm and 0 & lt Ssk, and preferably further satisfies 0.1 & lt Str & lt 0.7, with respect to surface roughness of a center of a leg portion which is visible when the main surface is observed in a direction perpendicular to the main surface on at least one side of the fastener tape or the fastener chain.
(2) Regarding the line roughness of the center of the leg portion visible when the main surface of at least one side of the fastener tape or the fastener chain is observed from the direction perpendicular to the main surface, the arithmetic average roughness (Ra) based on the roughness curve in the direction parallel to the longitudinal direction of the fastener tape is determined for each element after the wet shot blasting1) Is set as AveRa1(μm) the arithmetic average roughness (Ra) based on the roughness curve in the direction perpendicular to the longitudinal direction of the fastener tape2) Is set as AveRa2(mum), satisfies 0 ≦ AveRa1-AveRa2|/(AveRa1And AveRa2Any one of the larger) is less than or equal to 0.35.
Wet blasting is a method of blasting a slurry containing a medium (solid particles) and water from a blasting nozzle at a high speed by the force of a compressed gas. Therefore, in the wet blasting, the surface properties after wet blasting can be controlled so as to satisfy the above conditions by appropriately adjusting the material of the medium, the particle diameter of the medium, the concentration of the medium, the pressure of compressed gas, the treatment time, and the like, in accordance with the surface properties of the fastener elements before wet blasting.
As the material of the medium, for example, ceramic beads such as silicon carbide, silicon nitride, boron nitride, alumina, zirconia, and chromium oxide; metal-based microbeads made of steel or the like; glass beads such as borosilicate glass. The shape of the medium is not particularly limited, and is usually provided in a polyhedral shape or a spherical shape. From the viewpoint of preventing breakage of the medium, the medium preferably has a vickers hardness Hv higher than the vickers hardness Hv of the fastener element, more preferably has a vickers hardness 2 times or more, still more preferably 4 times or more, and still more preferably 6 times or more the vickers hardness of the fastener element.
When the specific gravity of the medium is high, kinetic energy at the time of ejection becomes large, and the medium easily enters the inside of the fastener tape. Therefore, from the viewpoint of preventing entry into the fastener tape, it is preferable to use a tape having a density of 6g/cm3The following medium is more preferably used, and the density is 5g/cm3The following medium is more preferably used, and the density is 4g/cm3The following medium is more preferably used, and the density is 3g/cm3The following media. However, if the specific gravity is too small, the working force is weak, and it is difficult to eliminate the streak pattern on the surface of the metal element, and therefore, it is preferable to use the metal element having a density of 1g/cm3The above medium is more preferably used at a density of 1.5g/cm3The above medium.
The medium having a large particle diameter has an advantage that it is not easy to enter the fastener tape, and also has an advantage that it is easy to remove by washing even if it enters the inside of the fastener tape. Therefore, the medium preferably has a median particle diameter of 10 μm or more, more preferably 50 μm or more, and still more preferably 100 μm or more. However, if the particle size of the medium is too large, the surface roughness to be obtained is too large, and therefore the median particle size of the medium is preferably 300 μm or less, more preferably 250 μm or less, and still more preferably 200 μm or less. Here, the median particle diameter means a particle diameter based on JIS Z8825: 2013 (particle size analysis-laser diffraction scattering method), the median particle size (volume basis) of the cumulative particle size distribution measured by a particle size measuring apparatus.
The concentration of the medium in the slurry is not particularly limited, and may be, for example, 5 vol.% to 40 vol.%, and typically 10 vol.% to 30 vol.%.
From the viewpoint of easily changing the texture of the fastener elements, the pressure (gauge pressure) immediately upstream of the outlet of the compressed gas injection nozzle for injecting the slurry is preferably 0.05MPa or more, and preferably 0.1MPa or more. From the viewpoint of suppressing damage to the fastener tape, the pressure (gauge pressure) immediately upstream of the outlet of the injection nozzle for injecting the compressed gas of the slurry is preferably 0.3MPa or less, and more preferably 0.2MPa or less from the viewpoint of reducing the amount of remaining medium in the fastener tape. As the type of the compressed gas, for example, inert gases such as nitrogen and rare gas can be used in addition to air.
When the spraying time of the slurry (the processing time of the wet shot) is short, the texture of the fastener element surface is not sufficiently changed, while the longer the spraying time, the more the fastener tape is damaged. Therefore, although the spraying time of the slurry also depends on the pressure of the compressed gas, it is preferable to set the treatment time per 1mm in the longitudinal direction of the fastener tape or the fastener chain to 0.05 seconds to 1 second, more preferably to 0.1 seconds to 0.5 seconds, and still more preferably to 0.1 seconds to 0.2 seconds.
When a medium having a large particle diameter is used, the pressure of compressed gas in wet blasting is increased, or the treatment time is prolonged, the Sa on the fastener element surface tends to increase. On the other hand, when a medium having a small particle diameter is used, the pressure of compressed gas in wet blasting is reduced, or the processing time is shortened, the Sa of the fastener element surface tends to be small.
The Str of the element surface approaches 1 in the case of the element after rolling. When wet blasting is performed, Str tends to be smaller than that in the state after rolling, but when the wet blasting condition is set to a medium having a large particle size in the same type of medium and the pressure of the compressed gas is reduced, Str tends to be smaller.
When the pressure of the compressed gas of the wet shot is increased or the shot time is prolonged, the Ssk of the fastener element surface tends to be small.
When the same medium is used, the pressure of the compressed gas is reduced, so that the surface of the fastener element isCoefficient of roughness variation (| AveRa)1-AveRa2|/(AveRa1And AveRa2Whichever is larger)) tends to be large, and when the compressed gas pressure is increased, the coefficient of variation tends to be small.
Basically, when the same medium is used, if the compressed gas pressure is increased, AveRa is obtained1And AveRa2The pressure of the compressed gas tends to be increased, and when the pressure of the compressed gas is decreased, AveRa is increased1And AveRa2The size of the coating tends to be small. However, the case where the particle size of the medium is small and the roughness of the treated surface is smaller than that of the untreated surface is excluded.
In the wet blasting, moisture contained in the slurry exerts an effect of washing the fastener tape, and thus the medium remaining in the fastener tape is small. However, when the medium remains, it is preferable to perform a step of removing the medium from the fastener tape after the wet blasting step from the viewpoint of enhancing the appearance. The method for removing the medium is not particularly limited, and spray cleaning, jet cleaning, vacuum cleaning, degassing cleaning, ultrasonic cleaning, cavitation cleaning, and the like can be mentioned. Among these, the cavitation cleaning is preferable in that the continuous fastener chain can be cleaned on-line and the medium removal efficiency is high.
The cavitation cleaning is a method of applying impact by cavitation generated by colliding high-pressure cleaning liquids with each other to a fastener stringer or a fastener chain, thereby removing a medium from the fastener tape. Fig. 4 is a schematic sectional view of the cavitation nozzle 24 in the case of performing cavitation cleaning while conveying the fastener chain 7. The cleaning liquid from the high-pressure pump (not shown) flows in the direction of the arrow through the pipe 22 and is discharged from the tip 28 of the cavitation nozzle 24 into the cleaning chamber 26. The tip ends 28 of the cavitation nozzles 24 are arranged to face each other in the front-rear direction in the conveying direction with the cleaning chamber 26 therebetween, and the cleaning liquid is discharged from the tip ends 28 of the cavitation nozzles 24 toward the fastener chain being conveyed, and when the cleaning liquids collide with each other in the cleaning chamber 26, cavitation occurs, and the medium is removed from the fastener tape by the impact of the cavitation. Thereafter, the used cleaning liquid flows from the cleaning chamber 26 to a return tank (not shown) through a pipe 30 together with the removed medium. A negative pressure is generated in the cavitation nozzle 24, and thus air also flows into the cavitation nozzle.
By cavitation cleaning, the medium can be removed with little damage to the fastener tape or the fastener element. As the cleaning liquid, for example, water can be used. The pressure at which the cleaning liquid collides can be set to, for example, 0.1 to 0.2MPa (gauge pressure) in terms of the pressure at the outlet immediately downstream of the outlet of the high-pressure pump (i.e., immediately after the outlet of the high-pressure pump 12509 ンプ, japanese). By using this cavitation cleaning, the medium can be removed from the fastener tape without damaging the fastener chain when wet shot blasting is performed under various conditions.
The fastener element for a slide fastener of the present invention can be subjected to various surface treatments as needed. For example, smoothing treatment, rust prevention treatment, coating treatment, plating treatment, and the like can be performed. These surface treatments may be performed at any timing before and after the wet blasting. However, when these surface treatments are performed after wet blasting, the surface treatments need to be performed within a range of conditions that do not lose the surface properties of the fastener elements intended in the present invention.

Hereinafter, examples of the present invention will be described, but these examples are provided for better understanding of the present invention and advantages thereof, and are not intended to limit the present invention.
< test No. 1>

A metal fastener chain of 27cm in length after degreasing and water washing was prepared. A plurality of fastener elements were fixed to a metal fastener chain along the side edges of each of a pair of fastener tapes (woven fabric made of polyester), and each of the fastener elements was made of a copper-zinc alloy (Cu: 85 mass% (85.4 at.%)) and Zn: 15 mass% (14.6 at.%). Further, the Vickers hardness Hv of the copper-zinc alloy is about 200. The composition is a value obtained without considering inevitable impurities, and the composition of the fastener element may contain inevitable impurities. The same applies to the following test examples. Each element is formed by pressing a Y-shaped bar material obtained by wire drawing, heat treatment, and cold rolling a wire material into an element shape, and is fixed to a fastener tape by compression. A total of 68 × 2 fastener elements are fixed to the fastener chain.

The degree of discoloration of the fastener tape becomes large as the fiber breakage and surface scratch (white) become large, and therefore evaluation is performed according to the following criteria. The results are shown in table 2.

[ Table 4]
(examination)
Test No. 1 is an example in which the wet blasting was not performed, and the variation coefficient of the roughness was large because of the presence of a stripe pattern.
In test nos. 3, 5, 7, 13, 15, and 17, although wet shot blasting was performed, at least one of Sa and Ssk was inappropriate, and therefore the fastener tape was damaged or the sliding resistance was large, which resulted in poor quality of the fastener chain.
On the other hand, in test nos. 2, 4, 6, 8 to 12, 14 and 16 in which wet shot treatment was performed and Sa and Ssk were controlled to be in appropriate ranges, the stripe pattern disappeared, the uniformity in appearance was high, the damage of the fastener tape was suppressed, and the sliding resistance was excellent.
In addition, test nos. 18 to 27 are examples in which the dry shot blasting was performed, and even if Sa and Ssk were appropriate when the dry shot blasting was performed, the quality of the fastener chain was insufficient in terms of the damaged state of the fastener tape and the sliding resistance. Further, as the dry blasting treatment time becomes longer, the amount of the medium remaining increases.
