Description

Zipper and zipper manufacturing method

The present invention relates to a zipper in which left and right chain rows are different in color, and a method of manufacturing the zipper.

As an example of a typical fastener stringer for a slide fastener, for example, a fastener stringer having a continuous fastener element row in which a monofilament made of a thermoplastic resin is formed into a loop shape or a zigzag shape and has meshing is known. A plurality of zipper elements of the head are connected one after another. Such a zipper tape is generally formed in such a manner that a sprocket row including a plurality of continuous zipper fasteners is continuously sewn to one side edge of a plain woven or knitted zipper chain by a suture ( The sprocket mounting portion is fixed.

Further, in the zipper manufactured by combining the zipper tapes as described above in the right and left, the sprocket chain and the zipper chain of the zipper chain are attached, for example, according to the color and design of the product to which the zipper to which the zipper is attached. The cloth is dyed to the desired color.

As a method of coloring a fastener element row and a fastener chain cloth of a fastener string, a method is generally known in which a fastener element is sewn on a fastener chain to form a fastener chain, and the obtained fastener chain is obtained. Two groups are engaged with each other to thereby form a zipper chain, and thereafter, the zipper chain is wound on a warp beam for dyeing, and the zipper chain is accommodated (impregnated) in a dyeing container together with a warp beam wound thereon Dyeing is carried out in the middle.

Further, as another method of coloring the element row and the fastener chain cloth, after forming a monofilament using a synthetic resin material in which a pigment having a desired color is previously kneaded, the monofilament is formed into a continuous element row. And additionally dyeing the zipper chain cloth, thereby The zipper and the zipper are colored separately. Thereafter, the obtained fastener element is sewn to the fastener chain cloth, thereby producing a fastener element chain in which the fastener element row and the fastener chain cloth respectively exhibit a desired color.

Further, Japanese Laid-Open Patent Publication No. Hei 11-70005 (Patent Document 1) discloses a zipper chain for zipper, that is, the left and right sprocket rows are dyed in a plurality of colors in the longitudinal direction, thereby exhibiting a rainbow color. The color of the full color of color.

In the fastener chain described in Patent Document 1, the fastener element is formed by using a monofilament of a thermoplastic synthetic fiber such as a polyamide or polyester, and has a predetermined length and a fixed period. A dye or pigment of a different color is used to color the monofilament, thereby rendering it a full color such as red, yellow, green, blue, etc., such as a rainbow color.

Then, by forming the monofilament dyed into a plurality of colors in a manner of winding into a loop shape, a continuous row of fastener elements is formed, and the obtained loop-shaped fastener element row is sewn to the fastener chain cloth. A side edge portion of the chain fabric, thereby manufacturing a fastener stringer.

Therefore, in Patent Document 1, since the fastener elements on the left side are dyed in a plurality of colors, and the fastener element rows on the right side are dyed in a plurality of colors, they can be finished without having appeared in the zipper of the past. The zipper of the chain of beautiful color of the full color. Thereby, when the zipper is attached to a zipper-mounted product such as clothes, the opening or the opening and closing portion of the zipper-attached product can exhibit a vivid pattern composed of a plurality of colors.

[Patent Document 1] Japanese Patent Laid-Open No. 11-70005

In recent years, in various articles, especially clothing, bags, shoes and other daily necessities, the zipper installed on the above various items has gradually been regarded as an element of design. Improve the overall appearance quality of products containing zippers. For example, regarding the zipper, it is required to dye the fastener element row and the zipper chain cloth into a desired color according to the use and design of the zipper-mounted product, and to dye the left and right chain tooth rows into a desired color, etc. .

However, when coloring the fastener element row and the fastener chain cloth, for example, as described above, after the fastener element is sewn on the fastener chain to form a fastener chain, the fastener chain is wound around the dyeing process. In the case where the dyeing treatment is performed by dipping on the shaft, substantially the left and right fastener element rows and the left and right fastener chain fabrics are all dyed using the dye of the same color. Therefore, there is a problem that it is difficult to make the color dyed between the left and right element rows different, and the color to be dyed between the element row and the fastener chain is different.

Further, in order to make the colors dyed between the left and right element rows different, for example, a method may be considered in which the left and right zipper chains are not in the state of the zipper chain but before the left and right sprocket rows are engaged. Each of the fastener tapes is wound around a different warp beam for dyeing, and the left and right fastener tapes are subjected to different dyeing treatments by dipping. After dyeing each of the left and right zipper tapes into a desired color in this manner, the zipper tapes of the left and right zippers are combined to produce a zipper, thereby obtaining different colors between the left and right chain rows. zipper.

However, in the case where the left and right zipper tapes are wound on different warp beams for dyeing in this manner, there is a case where the zipper is in the chain during the dyeing process. The position on the tooth row is shifted, and the interval between the engaging heads adjacent to each other in the longitudinal direction of the chain cloth is uneven. Therefore, compared with the case where the dyeing process is performed by winding the zigzag chain of the left and right fastener tapes in the state of the zipper chain for the right and left, for example, when manufacturing a zipper, it arises. The sprocket of the chain tooth row is deteriorated, the sliding property of the slider is lowered, and the zipper chain is easily bent.

On the other hand, for example, when the sprocket is dyed into a desired color by kneading the pigment into the synthetic resin material when the monofilament is formed, the color of the left and right element rows can be easily made different. However, a ring is produced by kneading a pigment into a synthetic resin material of a monofilament. In the case of a button-shaped fastener element, it is necessary to spun the monofilament for various colors, so that it is difficult to carry out a small amount of production, and in the case of forming a chain of one color, it is necessary to form a color which has been colored by the pigment. A large number of monofilaments of ~100 kg units are formed into zipper teeth.

However, in recent years, the diversification and personalization of users' needs have been progressing. In order to meet such demands, it is required to produce products in small quantities and to respond quickly to demands and fashion trends. On the other hand, the method of coloring the element rows by kneading the pigment into the synthetic resin material is based on the premise that mass production is performed, and thus there is a problem that it is difficult to flexibly cope with the demand in recent years, but it will incur manufacturing costs. Increased, slower response to demand and fashion trends. Further, in the case where the element rows are colored by kneading the pigment into the synthetic resin material, there is also a problem that the colored element rows cannot be formed transparent.

Further, in Patent Document 1, as described above, a zipper chain is described in which a monofilament is colored by a dye or a pigment of a plurality of different colors at a fixed length and at a fixed period, thereby The left and right chain tooth rows respectively present full color colors along the length direction.

However, in Patent Document 1, the specific method of coloring the monofilament is not described in detail, and actually, in order to dye the monofilament into several colors by a dye or a pigment, if it is used by using impregnation However, the dyeing treatment method to be carried out is extremely difficult to achieve, and it is necessary to perform a coloring treatment using, for example, a dedicated coloring device such as an inkjet method using a pigment-based ink or a dye-based ink. Therefore, there are cases where the manufacturing cost is increased and the production efficiency of the zipper is lowered.

Moreover, depending on the user's preference or fashion trend, it is sometimes desirable to have a left and right chain of teeth that are not full color, but a zipper that is dyed into a single color (monochrome) that is different from each other, so it is desirable A zipper having such a sprocket row dyed in a single color is provided at a lower price and more quickly.

The present invention has been made in view of the above prior problems, and its specific purpose is to provide A zipper is provided, which can prevent the manufacturing cost from increasing and the production efficiency of the zipper from being lowered, and the left and right chain rows are different from each other in a single color, and can stably ensure good bite and slip of the left and right fastener rows. Good slidability of the piece.

In order to achieve the above object, the zipper provided by the present invention is characterized in that, as a basic configuration, the zipper is formed on the opposite side edges of the first zipper and the second zipper. a first sprocket row and a second sprocket row zipper of the zipper chain, and the first sprocket row and the second sprocket row comprise synthetic resin, and are respectively dyed into a single color, and the first The element row and the second element row have different spectral reflectance curves.

In the slide fastener of the present invention, it is preferable that the first element row and the second element row include a synthetic resin of the same material as the main component.

Further, it is preferable that the first element row has a spectral reflectance curve different from the first fastener chain, and the second element row has a spectral reflectance curve different from the second fastener.

Further, in the slide fastener of the present invention, it is preferable that the first element row and the second element row include polyethylene terephthalate containing no titanium oxide.

Further, the first element row may include polyethylene terephthalate containing no titanium oxide, and the second element row may include polyethylene terephthalate containing 0.3% by weight or more of titanium oxide. The ester may further include polyethylene terephthalate containing 0.3% by weight or more of titanium oxide in the first element row and the second element row.

According to a second aspect of the invention, in the zipper of the present invention, the zipper has a first sprocket row and a first sprocket row on a side edge portion of the first zipper chain and the second zipper chain. a pair of second chain rows and a pair of fastener tapes; and the manufacturing method comprises the steps of: dyeing the first monofilament made of synthetic resin into a single color; and using the second resin of the synthetic resin to form a light reflectance curve a single color different from the first monofilament described above; The monofilament and the second monofilament are respectively formed into the first element row and the second element row; and the first element row and the second element row are respectively sewn to the first by a suture A fastener chain cloth and a side edge portion of the chain cloth of the second fastener chain cloth.

Further, in the zipper manufacturing method of the present invention, the zipper is characterized in that the zipper has a first sprocket row formed on a side edge portion of the chain of the first zipper chain cloth and the second zipper chain cloth. And a pair of second element rows and a pair of fastener tapes; and the manufacturing method includes the steps of: forming a first monofilament made of synthetic resin into the first element row, and dyeing the first element row into a single a color obtained by molding a second monofilament made of synthetic resin into the second element row, and a light color reflectance curve of the second element is different from the first element row; and The first sprocket row and the second sprocket row which have been dyed are sewn to the side edge portions of the first zipper chain and the second zipper chain by the suture.

The method for producing a slide fastener according to the present invention as described above preferably includes the step of setting the material of the first element row and the second element row to a polyethylene terephthalate containing no titanium oxide. And dyeing the first monofilament or the first sprocket row, the second monofilament or the second sprocket row by dyeing liquids different from each other.

Moreover, the method for manufacturing a slide fastener according to the present invention may include the steps of: setting a material of the first element row to polyethylene terephthalate containing no titanium oxide; and setting a material of the second element row a polyethylene terephthalate containing 0.3% by weight or more of titanium oxide; and the first monofilament or the first element row, and the second filament or the above by the same dyeing liquid The second chain of teeth is dyed.

Furthermore, the method for manufacturing a slide fastener according to the present invention may include the steps of: setting a material of the first element row to polyethylene terephthalate containing no titanium oxide; and setting a material of the second element row a polyethylene terephthalate containing 0.3% by weight or more of titanium oxide; and the first monofilament or the first sprocket row and the second monofilament or the dyeing liquid different from each other The second element row is dyed.

Furthermore, the manufacturing method of the zipper of the present invention may further comprise the following steps: The material of the first sprocket row and the second sprocket row is set to be polyethylene terephthalate containing 0.3% by weight or more of titanium oxide; and the first one is obtained by dyeing liquids different from each other The filament or the first sprocket row and the second monofilament or the second sprocket row are dyed.

In the zipper of the present invention, the monofilament or the element row (especially the fastener element) made of synthetic resin is directly subjected to dyeing treatment by dipping or the like, thereby eliminating the need for a dedicated coloring device such as an inkjet method. The sprocket row on the left side and the sprocket row on the right side can be dyed into a single different color and have different spectral reflectance curves.

According to the zipper of the present invention, the manufacturing cost is not greatly increased and the production efficiency of the zipper is greatly reduced, and the first and second element rows can stably exhibit colors different from each other in the spectral reflectance curves. Moreover, after the fastener element rows are fixed to the fastener chain by stitching, the obtained first and second fastener tapes of the right and left fastener tapes are respectively subjected to a dyeing treatment, and therefore, the dyeing treatment is not performed. When the position of the fastener element is shifted, the occlusion of the first and second element rows is deteriorated, the slidability of the slider is lowered, and the fastener chain is easily bent.

Further, the zipper of the present invention is different from the case where the skein is formed by kneading a pigment into a synthetic resin material of a monofilament as described above, and dyeing can be performed to form a desired color after forming a monofilament. Can be produced in small quantities. Therefore, the present invention can easily cope with, for example, a case where a plurality of types of zipper-mounted products are produced in a small amount, and can also promptly respond to user demands and fashion trends.

Furthermore, in the present invention, the color which exhibits a difference in the spectral reflectance curve refers to a specific portion of the fastener element by using a spectrophotometer (for example, the meshing head and the connection in the leg of the fastener element). The waveform of the spectral reflectance curve obtained by the measurement in the middle portion of the portion is different from that in the first element row and the second element row. Further, in this case, the first monofilament (the monofilament forming the first element row) and the second monofilament (the second stitch row formed) are formed by a spectrophotometer before the fastener element is formed into a fastener element. Silk) when making the measurement, the first order The spectral reflectance curve of the filament and the spectral reflectance curve of the second monofilament are of course different from each other.

In the slide fastener of the present invention, the first element row and the second element row are formed using a synthetic resin of the same material as the main component. Thereby, the properties and texture of the first and second element rows can be made uniform, and the quality of the meshing strength of the slide fastener and the slidability of the slider can be stably ensured. Further, in the present invention, the first element row and the second element row may be formed using a synthetic resin of a material different from each other in main components.

Further, in the slide fastener of the present invention, the first chain element row may have a color different from the first zipper chain cloth in the spectral reflectance curve. Further, the second element row may have a color different from the second zipper cloth in the spectral reflectance curve. Thereby, it is possible to easily provide the market with a zipper which has been difficult to produce before, and a zipper which is more in line with the needs of the user.

In the slide fastener of the present invention, the first element row and the second element row are formed using a monofilament containing polyethylene oxide-free polyethylene terephthalate. By forming the first element row and the second element row by using a monofilament made of a polyethylene terephthalate-free polyethylene terephthalate as described above, it is possible to have a synthetic resin material such as a monofilament as described above. A transparent, color-coded chain of teeth that cannot be achieved in the case of mixing pigments. Thereby, the change of the combination of the left and right chain rows of the different colors can be increased.

Further, in the zipper of the present invention, the first sprocket row may be formed using a monofilament containing polyethylene terephthalate containing no titanium oxide, and the second sprocket row may be contained containing 0.3 wt. More than % of titanium oxide of polyethylene terephthalate monofilament is formed.

By forming a monofilament using polyethylene terephthalate containing 0.3% by weight or more of titanium oxide, the color of the monofilament itself can be made white. Moreover, by dyeing the monofilament formed into white, the color dyed to the monofilament can be made more vivid.

In addition, the first element row is formed using polyethylene terephthalate containing no titanium oxide, thereby forming a transparent and colored element row, and the second element row is used. It is formed by containing polyethylene terephthalate of 0.3% by weight or more of titanium oxide, whereby the dyed color can be vividly exhibited. Therefore, it is easy to show the first relatively clearly The difference between the color of the 1 chain tooth row and the color of the 2nd chain tooth row. Moreover, the change in the combination of the left and right chain rows of the different colors can be further increased, and the new zipper which was previously impossible to manufacture can be provided to the market.

Further, in the slide fastener of the present invention, the first sprocket row and the second sprocket row may be formed by using a monofilament containing polyethylene terephthalate containing 0.3% by weight or more of titanium oxide. Thereby, it is possible to provide the market with a zipper in which the first chain tooth row and the second chain tooth row are dyed in different colors from each other.

Next, in the method for producing a slide fastener according to the present invention, first, a first monofilament made of a synthetic resin is dyed into a single color, and a second monofilament dyed by a synthetic resin is dyed differently from the first monofilament. The component light reflectance curve is different from the single color of the first monofilament. Thereby, the first monofilament and the second monofilament which exhibit mutually different colors can be easily obtained.

Then, by forming the obtained first monofilament and the second monofilament into a loop shape or a zigzag shape, a plurality of fastener elements are connected one by one to form a first chain which exhibits mutually different colors. The tooth row and the second chain of teeth.

Further, for example, if the monofilament is colored by a dyeing treatment by immersion, and then the colored monofilament is formed, thereby forming a continuous zipper element, when the monofilament is plastically deformed, When the surface of the filament is locally stretched, the dyed color is lightened or disappeared, partially discolored, and the like, and the appearance quality of the fastener element row is lowered.

However, in the present invention, the dyeing conditions and forming conditions of the monofilament are carefully studied to find suitable conditions, thereby preventing the dyed color from being formed even if the dyed monofilament is formed into a fastener element. It is faded or lightened to form a chain of teeth that is integrally and stably provided with a desired color.

Next, in the manufacturing method of the present invention, the formed first and second element rows are sewn to the side edge portions of the first and second fastener tapes by stitching, thereby forming a pair Zipper chain strap. Thereafter, one of the obtained pairs of zipper tapes is combined, a slider or the like is attached, thereby manufacturing a zipper.

By using the above-described manufacturing method, it is possible to stably manufacture the zipper of the single color in which the first element row and the second element row are respectively dyed with different spectral reflectance curves without causing a large increase in manufacturing cost. Moreover, according to such a manufacturing method, it is possible to prevent the seizure of the left and right element rows from being deteriorated, the sliding property of the slider being lowered, and the fastener chain being easily bent. Further, it is possible to easily cope with a situation in which a plurality of types of zipper-mounted products are produced in a small amount, and it is also possible to promptly respond to user demands and fashion trends.

Further, in another method of manufacturing a slide fastener according to the present invention, first, a first monofilament made of a synthetic resin is molded into a first element row, and the first element is discharged into a single color. Further, unlike the first element row, the second monofilament made of synthetic resin is formed into a second element row, and the light reflectance curve of the second element tooth discharge component is different from that of the first element row The single color. Thereby, the first element row and the second element row which exhibit colors different from each other can be easily formed.

Next, the formed first and second element rows are sewn to the side edge portions of the first and second fastener chain fabrics by stitching, thereby forming a pair of fastener tapes. Thereafter, one of the obtained pair of zipper tapes is combined, and a slider or the like is attached, thereby manufacturing a zipper.

By using the manufacturing method as described above, it is possible to stably manufacture a single color in which the first element row and the second element row are respectively different in light reflectance curves without causing a large increase in manufacturing cost. Zipper.

Moreover, in this case, after the fastener element row is formed, the chain element row is attached to the fastener chain cloth before the dyeing process is performed, so that the seizure of the left and right chain tooth rows is prevented from being deteriorated and slipped due to the dyeing process. The slidability of the piece is lowered, and the zipper chain is easily bent. Further, it is possible to easily cope with a situation in which a plurality of types of zipper-mounted products are produced in a small amount, and it is also possible to promptly respond to user demands and fashion trends.

In the production method of the present invention as described above, the first chain of teeth and the second row of teeth can be formed using polyethylene terephthalate containing no titanium oxide, and by different dyeing liquid pairs The first monofilament or the first element row, and the second or second element row are dyed. borrow Thereby, the zipper having the first and second sprocket rows which are transparent and colored can be stably produced, and the change of the combination of the sprocket rows of the left and right colors can be increased.

Further, in the production method of the present invention, a polyethylene terephthalate-free polyethylene terephthalate may be used to form a first fastener element row, and a polyethylene terephthalate containing 0.3% by weight or more of titanium oxide may be used. The second element row is formed, and the first monofilament or the first element row, and the second or second element row are dyed by the same dyeing liquid.

Thereby, the first element row can be formed into a transparent and colored chain row. Further, by forming the second element row by using polyethylene terephthalate containing 0.3% by weight or more of titanium oxide, the color dyed by the dyeing treatment can be made more vivid than the first element row.

Therefore, even if the first monofilament or the first sprocket row, and the second monofilament or the second sprocket row are dyed by the same dyeing liquid, the color of the first sprocket row and the second chain can be made. The difference in the color of the rows of teeth is relatively clear, so that the zippers of the first and second element rows having significantly different colors can be stably produced. Further, by this, it is possible to further increase the combination of the combination of the left and right chain rows of the different colors, and to provide the market with a new type of zipper which was previously impossible to manufacture.

Further, in the present invention, the dyeing by the same dyeing liquid includes the following two cases: the first monofilament or the first strand row, and the second monofilament or the second chain row are simultaneously or sequentially impregnated Dyeing treatment in the same dyeing container; and immersing the first monofilament or the first sprocket row, and the second monofilament or the second sprocket row in different dyeing containers containing the same dyeing liquid The dyeing process is performed.

Further, in the production method of the present invention, the first chain row can be formed using polyethylene terephthalate-free polyethylene terephthalate, and polyethylene terephthalate containing 0.3 wt% or more of titanium oxide can be used. The second element row is formed, and the first monofilament or the first element row, and the second monofilament or the second element row are dyed by the dyeing liquids different from each other.

Thereby, the zipper of the first and second element rows having more distinct colors can be stably produced. Moreover, the change in the combination of the left and right chain rows of the different colors can be further increased, and the new zipper which was previously impossible to manufacture can be provided to the market.

Further, in the production method of the present invention, polyethylene terephthalate containing 0.3% by weight or more of titanium oxide may be used to form the first element row and the second element row, and are different from each other. The dyeing liquid is dyed on the first monofilament or the first fastener element row, and the second monofilament or the second element row. Thereby, the zipper having the first and second sprocket rows dyed in a more vivid color can be stably produced, and the change in the combination of the left and right sprocket rows of different colors can be increased.

Further, in both of the first and second fastener tapes 12a and 12b of the first embodiment, the third color which is dyed by the dyeing process is provided, and in the present invention, the color of the fastener tape 12 is Not particularly limited. For example, as shown in FIG. 4, the first zipper chain cloth 12a on the left side and the second zipper chain cloth 12b on the right side may have mutually different colors. In this case, the color of the first fastener stringer 12a on the left side may be different from the first color of the first fastener element row 11a, and the color of the second fastener stringer 12b on the right side and the second fastener element row 11b may be used. The second color is different. Further, a desired pattern can be arbitrarily applied to the front surface of the chain fabric of the first and second fastener chain fabrics 12a and 12b or the back surface of the chain fabric.

Further, in the first embodiment, the first and second fastener tapes 12a and 12b are formed by a woven structure. However, in the present invention, the form of the fastener chain 12 is not limited, and for example, the fastener chain 12 is formed. The material and thickness of the warp and weft may be arbitrarily set, and the fastener chain 12 may be formed by braiding.

Each of the first and second element rows 11a and 11b on the left and right sides is formed by connecting a plurality of fastener elements 15 in a loop shape one by one, and the core string 16 is inserted into each of the fastener elements 15 described below. In the state between the leg portion 15b and the lower leg portion, the first and second fastener tapes 12a are respectively sewn by the double chain stitches of the suture 14 (the first suture line 14a on the left side or the second suture line 14b on the right side). The side edge of the chain of 12b. Furthermore, in the present invention, the core cord 16 may not be used. The first and second element rows 11a and 11b are sewn to the first and second fastener tapes 12a and 12b, respectively.

Each of the fastener elements 15 has an engaging head portion 15a, a self-engaging head portion 15a extending in the chain width direction, a leg portion 15b and a lower leg portion, and extending from the upper leg portion 15b or the lower leg portion to be adjacent to the longitudinal direction of the zipper. The zipper element 15 is connected to the connecting portion 15c. Further, in the present invention, the engaging head portion 15a of the fastener element 15 extends from the upper and lower leg portions, and the so-called lower leg portion refers to the leg portion on the side directly contacting the fastener chain cloth 12, and the so-called upper leg portion 15b refers to the foot portion. It is disposed on the foot away from the side of the fastener chain cloth 12.

The engaging head portion 15a of the fastener element 15 has a portion that is formed in the vertical direction so as to straddle the upper leg portion 15b and the lower leg portion, and bulges in the front-rear direction in the intermediate portion in the up-and-down direction. The upper leg portion 15b is disposed on the upper side of the core string 16 from the meshing head portion 15a in the width direction of the slide fastener. The lower leg portion is disposed between the core string 16 and the fastener stringer 12 so as to extend substantially parallel to the upper leg portion 15b in the width direction of the slide fastener.

The connecting portion 15c connects the leg portion 15b of each of the fastener element teeth 15 and the lower leg portion of the fastener element 15 adjacent to the front side of the fastener element 15 (in other words, the lower leg portion of each of the fastener elements 15 and The zipper element 15 is connected to the upper leg 15b of the zipper element 15 adjacent to the rear side.

In the first embodiment, the first element row 11a on the left side is formed by dyeing the transparent first monofilament 13a containing the polyethylene terephthalate-free polyethylene terephthalate. The single color of the first color (for example, blue) different from the third color of the first zipper chain cloth 12a on the left side, and further, the dyed first monofilament 13a is formed into a loop shape.

Further, the second chain element row 11b on the right side is formed by dyeing the second monofilament 13b including the transparent polyethylene terephthalate containing no titanium oxide to the second side on the right side. The third color of the zipper chain cloth 12b is different from the first color of the first color (for example, light blue) different from the first color of the first sprocket row 11a on the left side, and the second color is dyed. The monofilament 13b is formed into a loop shape.

In this manner, the first color of the first element row 11a on the left side is different from the second type of color of the second element row 11b on the right side, and the first element row 11a is further provided. The first color is different from the third color of the first fastener chain cloth 12a, and the second color of the second element row 11b and the third type of the second fastener chain 12b are provided. The color is different, whereby the color of the zipper 1 is made bright, and the appearance quality of the zipper 1 and the appearance quality of the final product manufactured by attaching the zipper 1 to the zipper-mounted product can be effectively improved.

Here, the first color to the third color are different from each other, and the first and second element rows 11a and 11b (or the first and second filaments 13a and 13b) are used by the spectrophotometer. The waveforms of the respective spectral reflectance curves obtained by the measurement of the fastener chain 12 are different from each other.

In particular, when the spectroscopic reflectance curve of the first element row 11a and the second element row 11b is measured by a spectrophotometer, a certain portion of the fastener element 15 is, for example, above the fastener element 15 The spectral reflectance curve of the intermediate portion of the engaging portion 15a and the connecting portion 15c in the leg portion 15b is measured, and the spectral reflectance curves measured for the specific portion are compared with each other, thereby determining the first element row 11a. The color is similar to the color of the second chain row 11b.

Further, for example, when the first element row 11a and the second element row 11b are formed using the transparent monofilament 13 as in the first embodiment, there is a case where the spectrophotometer is used for splitting light. When the reflectance curve is measured, the light transmitted through the transparent element row 11 (or the monofilament 13) is reflected at the background on the back side of the element row 11 (or the monofilament 13), so the spectral reflectance curve The waveform is affected.

Therefore, when at least one of the first element row 11a and the second element row 11b is transparent, when the color difference between the first element row 11a and the second element row 11b is judged, for example, preparation is made. Two kinds of backgrounds are used to measure the spectral reflectance curves of the first and second element rows 11a and 11b (or the first and second filaments 13a and 13b) by a spectrophotometer for each background, as long as it is on any background. The spectral reflectance curves of the first first element row 11a and the second element row 11b (or the first monofilament 13a and the second monofilament 13b) are different from each other, and the color of the first element row 11a and the second element row are different. The colors of 11b are different from each other.

Further, in the first embodiment, the pair is the same in the first color of the first element row 11a, the second color of the second element row 11b, and the third color of the fastener chain 12. When the color is judged by a different color, the RGB value of each part is derived from the measured spectral reflectance curve, and the RGB values of the obtained colors are compared, whereby the first color can be easily judged. The similarities and differences of the third color (especially the similarities and differences between the first color and the second color).

In this case, the RGB values of the first color to the third color may be that the zipper chain cloth 12 and the first and second sprocket rows 11a and 11b are photographed by the digital camera, and the image is obtained according to the shooting. The RGB values in the first to third colors are analyzed. In this case, the spectral reflectance curves measured from the respective portions by the spectrophotometer are of course different as long as the RGB values of the respective portions analyzed based on the captured image are different.

In particular, when comparing the RGB value of the first element row 11a analyzed based on the image obtained by imaging with the RGB value of the second element row 11b, it is preferably performed by using a spectrophotometer. In the same manner, the RGB values of the intermediate portion of the meshing head portion 15b and the connecting portion 15c in the specific portion of the fastener element 15 such as the fastener element 15 are obtained and compared. Further, in this case, the RGB values of the first to third colors of the subtractive color processing may be compared to determine the similarities and differences of the colors.

Further, in the first and second fastener stringers 10a and 10b on the right and left in the first embodiment, the respective fastener rows 11 are sewn to the suture 14 on the fastener stringer 12 (the first suture 14a on the left side) And the second suture line 14b) on the right side is formed to be opaque, and exhibits the first color of the first element row 11a, the second color of the second element row 11b, and the third color of the fastener chain 12. The fourth color is different (for example, black). Further, in the present invention, the suture 14 of the suture element row 11 may be formed to be transparent or used without being colored by a dyeing treatment or the like.

Moreover, the left and right core cords 16 of the first embodiment are not dyed, but in the present invention, the core cord 16 may be dyed in any color, for example, the color of the core cord 16 may be dyed and the above. Any one of the first color to the fourth color, or a color different from any of the first color to the fourth color.

Next, a method of manufacturing the above-described slide fastener 1 of the first embodiment will be described.

First, the first monofilament 13a and the second monofilament 13b made of a polyethylene terephthalate-free polyethylene terephthalate are produced by a melt spinning method to a specific length. Further, in addition to the first and second monofilaments 13a and 13b, the first and second fastener zippers 12a and 12b which are woven into the left and right are woven flat by using the synthetic fibers dyed in the third color.

Next, the produced first monofilament 13a is wound around a warp beam for dyeing, and the first monofilament 13a is subjected to a dyeing treatment under specific dyeing conditions. In the dyeing process of the first monofilament 13a, the first monofilament 13a and the warp beam wound with the first monofilament 13a are immersed in a dyeing container containing a specific dyeing liquid, and the first The monofilament 13a is dyed as a single first color.

Further, the second monofilament 13b to be produced is separated from the dyeing process of the first monofilament 13a, and is also wound around a warp beam for dyeing and subjected to dyeing treatment under specific dyeing conditions. In the dyeing process of the second monofilament 13b, the second monofilament 13b and the warp beam around which the second monofilament 13b is wound are collectively immersed in a specific one different from the dyeing liquid of the first monofilament 13a. In the dyeing container of the dyeing liquid, the entire second filament 13b is dyed into a single second color.

Then, the first monofilament 13a uniformly dyed into the first color is supplied to the element forming device, and the element forming step of forming the first element row 11a is performed under specific molding conditions. In the sprocket forming step, the first monofilament 13a is press-formed at a predetermined interval, and the meshing head portion 15a is formed, and the first monofilament 13a is formed into a loop shape. The first element row 11a.

By performing the sprocket forming step, the first element row 11a uniformly colored in the first color can be stably formed, and the first color dyed by the dyeing process is not faded or lightened. . Further, the second monofilament 13b is subjected to the same element forming step as the first monofilament 13a under the specific molding conditions, and the second chain uniformly colored in the second color is formed. Tooth row 11b.

Further, in the first embodiment, as described above, after dyeing the first and second filaments 13a and 13b by the dyeing treatment, the dyed first and second filaments 13a and 13b are sprocketed. In the forming step, the first and second element rows 11a and 11b respectively dyed into specific colors and having different spectral reflectance curves are formed.

However, in the present invention, before the first and second monofilaments 13a and 13b are subjected to the dyeing treatment, the first and second monofilaments 13a and 13b are subjected to the element forming step to form the first and second element rows. 11a and 11b, and immersing the first and second element rows 11a and 11b formed in the dyeing container in which the dyeing liquid is contained, and dyeing the first and second element rows 11a and 11b, respectively. This also forms the first and second element rows 11a and 11b which are dyed to a specific color.

Then, in the first embodiment, after the dyed first and second element rows 11a and 11b are formed as described above, for example, as shown in FIG. 5, the core strings 16 are respectively inserted into the obtained first one. The element row 11a and the second element row 11b are disposed between the leg portion 15b and the lower leg portion, and the first element row 11a and the second element row 11b are engaged with each other. Further, the first element row 11a and the second element row 11b through which the core string 16 is inserted are sewn to the first fastener stringer 12a by the double chain stitch of the suture 14 in a state of being engaged with each other. The side edge portion of the chain cloth and the side edge portion of the chain of the second fastener chain cloth 12b.

Thereby, the first fastener stringer 10a on the left side and the second fastener stringer 10b on the right side are produced (in this case, the fastener chain in a state in which the first element row 11a and the second element row 11b are engaged) are manufactured.

Thereafter, the sliders 30 are attached to the first and second element rows 11a and 11b of the first and second fastener stringers 10a and 10b obtained, and are applied to the first and second fastener stringers 10a and 10b. The stopper 5 and the detachable insert 6 are formed, whereby the zipper 1 of the first embodiment shown in Fig. 1 is manufactured.

In the zipper 1 of the first embodiment manufactured in the above manner, the first sprocket row 11a on the left side and the second sprocket row 11b on the right side contain the same polyethylene terephthalate, and are uniformly provided with each other. The same single color has different spectral reflectance curves.

In this case, it is possible to prevent the color dyed to the first and second element rows 11a and 11b from being faded or lightened when the zipper is manufactured due to the dyeing process, and the first and the third sides are not caused. The splicing of the sprocket rows 11a and 11b is deteriorated, the slidability of the slider 30 is lowered, and the zipper chain is easily bent in the width direction of the chain fabric.

Further, in the slide fastener 1 of the first embodiment, the left and right first and second element rows 11a and 11b are formed by using the colored transparent monofilaments 13, so that the respective element rows 11a and 11b do not each other. The same color, and it looks like a dazzling flash. In addition, not only the colors of the first and second element rows 11a and 11b are different, but also the color of the first element row 11a on the left side is different from the color of the first fastener chain 12a on the left side, and the second side on the right side. The color of the element row 11b is different from the color of the second zipper chain 12b on the right side. Therefore, the zipper 1 of the first embodiment is rich in color, beautiful in appearance, and excellent in appearance quality.

In particular, in the first embodiment, the left and right first and second element rows 11a and 11b are not colored by the inkjet method, but are relatively simple to be dyed by being immersed in the dyeing liquid. Since the coloring is performed, the zipper 1 excellent in appearance can be manufactured at low cost and high efficiency.

Further, the zipper 1 of the first embodiment in which the colors of the first and second element rows 11a and 11b are different as described above is mixed with a synthetic resin material such as the prior art to form a fastener element to form a fastener element. In other cases, it can be produced in a small amount, and therefore, it is possible to easily cope with, for example, a case where a plurality of types of zipper-mounted products are produced in a small number of varieties, and the user's needs and fashion trends can be quickly responded to.

Example 2

Fig. 6 is an enlarged view of an essential part showing an enlarged main portion of the first and second fastener stringers in the slide fastener of the second embodiment.

In the zipper 2 of the second embodiment, the second sprocket row 21b on the right side and the second zipper chain cloth 12b on the right side are sewn to the right side, compared to the zipper 1 of the first embodiment. The second suture 24b is different, but the other components and parts are the same as the above. The zipper 1 of the first embodiment is formed substantially in the same manner. Therefore, in the second embodiment, members and portions having substantially the same configurations as those of the slide fastener 1 of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In the first fastener stringer 10a on the left side in the second embodiment, the first element row 11a is inserted into the core string 16 in the same manner as the first fastener string 10a on the left side in the first embodiment. In the state between the upper and lower legs, the side seam side edge portion of the first fastener stringer 12a is sewn by the double chain stitch of the first stitching line 14a.

On the other hand, in the second fastener stringer 20b on the right side in the second embodiment, the second element row 21b having a different appearance from the second element row 11b in the first embodiment is attached to the core string. 16 is inserted into the upper leg portion 15b and the lower leg portion, and is sewn to the chain side edge portion of the second fastener stringer 12b by the double chain stitch of the second stitch 24b.

The second element row 21b of the second embodiment is formed by dyeing a white second monofilament 23b containing polyethylene terephthalate containing 0.3% by weight or more of titanium oxide. a color different from the first color of the first sprocket row 11a on the left side and the second color (for example, light blue) different from the third color of the second zipper chain cloth 12b, and further The dyed second monofilament 23b is formed into a loop shape.

By setting the content of the titanium oxide contained in the second monofilament 23b of the second embodiment to 0.3% by weight or more, the second monofilament 23b can be made opaque, and the color of the second monofilament 23b itself can be made pure. White.

In this way, the second filament 23b to be spun is formed into a white color, whereby when the second filament 23b is dyed into the second color by the dyeing treatment, it is transparent to, for example, the above-described first embodiment. When the second monofilament 13b is dyed, the second dyed color can be made brighter than white. In this case, in order to appropriately secure the strength of the second element row 21b, the content of the titanium oxide contained in the second monofilament 23b is preferably 1.0 wt% or less.

Furthermore, in the prior art, for example, the zipper chain is wound on the warp beam for dyeing, and the zipper chain and the chain row are dyed in the state of the zipper chain. In the case of the case, the polyester forming the element row contains a very small amount of titanium oxide in an amount of less than 0.1% by weight.

By including a very small amount of titanium oxide in the polyester in this way, the monofilament itself can be formed into a pale white (in other words, a white and turbid state), so that the dyed chain teeth can be arranged. The color is slightly better. However, in the previous dyeing process, the dyeing is performed in the state of the zipper chain (in other words, the state in which the monofilament is formed into a loop-shaped and bent chain-toothed row), and thus the dyed strand row is A stain is produced on it.

Therefore, previously, there is also a case where, if the content of the titanium oxide in the monofilament is increased to 0.1% by weight or more, although the monofilament can be formed whiter and the color development is more vivid, when When the colored spots are generated, the white color of the monofilament itself is easily recognized from the outside, and as a result, the stain at the time of dyeing is also easily discriminated, and the appearance quality of the zipper is lowered. Therefore, in the dyeing treatment for dyeing the fastener chain in the prior art, in order to make the coloration bright, the content of the titanium oxide in the monofilament was not set to 0.1% by weight or more.

On the other hand, in the second embodiment, the second monofilament 23b is wound on the warp beam shaft in a state of being unbent before the second element row 21b formed into a loop shape. On the other hand, the dyeing treatment of the second monofilament 23b is performed, so that it is difficult to cause color unevenness on the dyed second filament 23b.

Therefore, even if the content of the titanium oxide in the second monofilament 23b is set to 0.3% by weight or more, the second monofilament 23b formed into a pure white color is dyed, and the second monofilament can be prevented from being caused by the color unevenness. The white color of 23b itself is recognized from the outside, so that the color of the dyed second monofilament 23b appears more vivid.

Further, in the second embodiment, the first stitching line 14a that sews the first fastener element row 11a on the left side to the first fastener element chain 12a exhibits the first color and the second chain of the first element row 11a. The second color of the tooth row 21b and the fourth color of the third color of the fastener chain cloth 12 are different. Further, the second stitch 24b which sews the second fastener element row 21b on the right side to the second fastener tape 12b exhibits a fifth color different from the first color to the fourth color. By this, you can make this The zipper 2 of Embodiment 2 appears to be more vivid.

In the case of manufacturing the zipper 2 of the second embodiment, first, the first monofilament 13a made of polyethylene terephthalate-free polyethylene terephthalate is produced by a melt spinning method to a specific length. And a white second monofilament 23b containing polyethylene terephthalate containing 0.3% by weight or more of titanium oxide.

Next, in the same manner as in the first embodiment, the first monofilament 13a is dyed into a single first color. Further, the second monofilament 23b is wound around the warp beam for dyeing, and the second monofilament 23b and the warp beam are collectively immersed in a specific dyeing liquid different from the dyeing liquid of the first monofilament 13a. In the dyeing container, the second monofilament 23b is dyed into a single second color.

Then, by performing the element forming step on the dyed first and second monofilaments 13a and 23b, the first and second spectrally different color spectral reflectance curves are formed. The second element row 11a, 21b. Then, similarly to the case of the first embodiment, the obtained first and second element rows 11a and 21b are sewn to each other by the double chain stitch of the suture 14 in a state of being engaged with each other. The side edge portion of the chain of the second fastener chain cloths 12a and 12b.

Thereby, the first fastener stringer 10a on the left side and the second fastener stringer 20b on the right side are manufactured. Thereafter, the sliders of the second embodiment are attached to the first and second fastener stringers 10a and 20b obtained, and a stopper and a detachable insert are formed, whereby the zipper 2 of the second embodiment is manufactured.

In the zipper 2 of the second embodiment as described above, the first sprocket row 11a on the left side and the second sprocket row 21b on the right side contain polyethylene terephthalate having the same main component, and are uniformly provided. A single color that is different from each other by the dyeing treatment of the monofilament 13.

In this case, it is possible to prevent the colors dyed by the first and second element rows 11a and 21b from being dyed by the dyeing process from being faded or lightened when the zipper is manufactured, and the first and second sides of the left and right are not generated. The nip of the element rows 11a and 21b is deteriorated, the slidability of the slider 30 is lowered, and the zipper chain is easily bent in the width direction of the chain cloth.

Further, in the zipper 2 of the second embodiment, the first sprocket row 11a on the left side is passed through The monofilament 13 is dyed and colored in a dazzling manner. On the other hand, the second element row 21b on the right side is colored in a vivid manner by dyeing the white second monofilament 23b. . Therefore, by the synergistic effect of the first and second sprocket rows 11a, 21b on the left and right, the difference between the first and second sprocket rows 11a, 21b can be more clearly expressed, and it has been seen before. The new look quality.

Further, in the zipper 2 of the second embodiment, similarly to the slide fastener 1 of the first embodiment, the zipper 2 is immersed in the dyeing liquid to perform coloring, so that the appearance quality can be manufactured at low cost and with high efficiency. In addition, since the zipper 2 is excellent in production, it is possible to easily cope with, for example, the case where a zipper-mounted product is produced in a small number of varieties, and the user's needs and fashion trends can be quickly responded to.

Further, in the second embodiment, in the production of the first and second fastener tapes 10a and 20b, when the first and second filaments 13a and 23b are dyed, different dyeing liquids are used. Thereby, the first and second element rows 11a and 21b having mutually different spectral reflectance curves are formed.

However, the first monofilament 13a of the second embodiment is made of polyethylene terephthalate containing no titanium oxide and is formed to be transparent. On the other hand, the second monofilament 23b contains 0.3 wt% or more of titanium oxide. Made of polyethylene terephthalate and formed in white.

Therefore, when the first and second monofilaments 13a and 23b are subjected to the dyeing treatment, the same dyeing liquid is used for the first and second monofilaments 13a and 23b as described above instead of using different dyeing liquids. The dyeing liquid is dyed, and the first and second element rows 11a and 21b having mutually different spectral reflectance curves can be formed.

In this case, in the dyeing process of the first and second filaments 13a and 23b, the first monofilament 13a and the second monofilament 23b are wound around the same or different dyeing warp beams, and The monofilament 13a and the second monofilament 23b are simultaneously immersed in the dyeing container containing the single dyeing liquid together with the warp beam, whereby the first monofilament 13a and the second monofilament 23b can be used with the same dyeing liquid. By dyeing, the first and second element rows 11a and 21b which are different from each other can be obtained.

Further, for example, when the first monofilament 13a and the second monofilament 23b are respectively wound around different warp beams for dyeing, the first monofilament 13a and the second monofilament 23b may be sequentially immersed in the swell. The first monofilament 13a and the second monofilament 23b are dyed in a dyeing container in which a single dyeing liquid is placed.

Further, when the first and second monofilaments 13a and 23b are dyed using the same dyeing liquid, the first monofilament 13a and the second monofilament 23b may be wound around different warp beams for dyeing. In the dyeing container in which the dyeing liquid having the same color is prepared, the first monofilament 13a and the second monofilament 23b are respectively immersed in different dyeing containers to perform dyeing treatment.
