Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a partial perspective view showing a slide fastener (100) according to a first embodiment of the present invention. Fig. 2 is a view showing the zipper (100) of Fig. 1 taken from a section. The zipper (100) includes a pair of left and right chain cloths (101), a chain gear row (104) mounted along a side edge of each chain cloth (101), and a sliding member for separating and meshing the element tooth row (104) (105). Furthermore, only a portion of the slider (108) of the slider is shown in FIG. Further, as shown in Fig. 3 or Fig. 4, an upper stopper (112) is provided at the upper end of the element row (104), and a detachable insert (110) is provided at the lower end.

The specific structure of the zipper (100) of Fig. 1 will be described in detail below. The chain cloth (101) includes a first tape member (102) on the front side and a second tape member (103) on the back side. For the sake of convenience, the side of the slider (105) on which the tab (108) is attached is referred to as the front side, and the opposite side is referred to as the back side, but is not limited thereto. On the side edge of one of the chain cloths (101) by sewing A loop-shaped resin element (104) is sewn by the yarn (107). Within the chain row (104), a core string (106) is provided for puncturing the stitching yarn (107) during sewing to attach the element row (104) to the chain fabric (101). The slider (105) is slidable along the left and right chain rows (104), and when the element rows (104) pass through the inside of the slider, the element rows (104) are engaged or disengaged in accordance with the sliding direction of the slider. For example, the slider is engaged by sliding in the direction of the upper stop and is separated by sliding in the direction of the detachable insert. Here, the sliding direction is consistent with the longitudinal direction of the chain cloth. Further, a direction horizontal to the surface of the chain cloth and orthogonal to the longitudinal direction is referred to as a width direction of the chain cloth, and is also referred to as a left-right direction. Further, the direction perpendicular to the surface of the chain cloth is referred to as the front and back direction.

In the present embodiment, the first tape member (102) and the second tape member (103) are separately woven, and the chain cloth (101) is formed by laminating the layers. Both of them are integrated by sewing the side edge portions by the sewing yarns (107) of the sewing element rows (104). As an advantage of this method, since the same tape member can be manufactured, inventory can be reduced, and manufacturing can be performed without error in the manufacture of the chain cloth (101).

Different characters, patterns, colors (colors of one color, or colors including two or more colors) may be respectively provided on the outer surfaces of the respective tape members (102, 103) or any combination thereof (hereinafter, abbreviated as "patterns, etc."). The outer surface of each of the tape members (102, 103) is exemplified as an observation view 2, and the first tape member (102) is opposite to the surface (back surface) opposite to the second tape member (103). The surface (surface) indicates a surface (surface) opposite to the surface (back surface) opposite to the first tape member (102) in the second tape member (103). One of the zippers having the chain cloth (101) having different patterns on the back of the watch is exemplified in Fig. 3 (the front side) and Fig. 4 (the back side). The chain cloth (101) comprises two tape members (102, 103) on the back of the watch, so that the tape transfer from the front side of the tape member (102) to the back side of the tape member and the back side can be prevented. The tape member is transferred to the tape member (102) on the front side. Therefore, it is possible to present a highly independent design on the back of the watch.

The dyeing method of the chain cloth (101) is not particularly limited, but for example, a disperse dye, Dyeing of reactive dyes, inkjet printing, transfer printing, etc. In the case of dip dyeing or reactive dyeing, etc., the first tape member (102) and the second tape member (103) may be dyed by dyeing, respectively, and then the two tape members are combined, and The chain rows (104) are integrated by stitching. In the case of printing or the like of inkjet or transfer printing, the two backing tape members (102, 103) and the element tooth row (104) can be integrated by stitching, by inkjet or Printing and dyeing. The dyeing of the chain cloth (101) may also be performed before or after the chain element row (104) is attached to the chain cloth (101), but since the chain tooth row (104) can also be dyed at the same time, it is preferred to use the chain. The tooth row (104) is attached to the chain cloth (101), and is dyed after the chain tape is produced. However, when it is desired to have the chain row (104) and the chain cloth (101) in different colors, it is preferable to perform dyeing of the element row (104) before mounting the element row (104), and thereafter, mounting In the chain cloth. In addition, when dyeing is performed in a state in which the left and right chain fabrics (101) are separated, the pattern or the like is easily displaced when the left and right fastener tapes are meshed and combined, and it is difficult to smash the left and right chain rows (104). Continuous pattern and so on. Therefore, it is more preferable to attach the element row (104) to the chain cloth (101), make the chain belt, and then integrate the two chain belts by the meshing of the opposite element rows (104). Dyeing is carried out. As a result, as shown in FIG. 3 and FIG. 4, even when a pattern that straddles the left and right chain cloth is applied, a pattern having a good pattern or the like can be processed without causing a positional shift.

Referring to Fig. 5, there is shown a view obtained by observing the zipper of the second embodiment of the present invention from a cross section. In the present embodiment, a waterproof film (109) made of a synthetic resin made of a transparent and thermoplastic elastomer is attached to the outer surface of the first tape member (102). The attachment of the film (109) can be carried out by means of an adhesive. The pattern imparted to the outer surface of the first tape member (102) or the like can be prevented from being hidden by making the waterproof film transparent. The side edges of the element row (104) side of the waterproof film (109) protrude from the side edges of the first tape member (102) and the second tape member (103), and abut against the opposite waterproof film. The side edge of (109). Thereby, it is possible to prevent water from entering from the gap between the left and right cloth members (102, 103), thereby contributing to an improvement in water repellency.

Referring to Fig. 6, a partial view of the third embodiment of the present invention is observed from the front side. The map of the chain. In the first embodiment, the element row (104) is attached to the tape member (103) on the back side, but in the present embodiment, the difference is that the element row (104) is attached to the front side (sliding) The tape member (102) on which the side of the pull tab is mounted. As described above, the chain element row (104) is attached to the chain cloth (101), the chain tape is produced, and the pair of chain elements (104) are engaged with each other to separate the two chain belts. Thereby, the star mark of the center is not displayed at the boundary between the left and right chain cloths, and the floor mark is presented.

Further, in the present embodiment, as shown in Fig. 7, two sheets of tape members (102, 103) are formed by folding back a piece of the tape member to the side edge of the element attaching portion (201). As an advantage of this method, the following aspects can be cited: It is possible to form two tape members (102, 103) of the front and back only by manufacturing one wide strip member.

The zipper of the present invention can be used as an opening and closing member of an article by sewing to various articles, for example, for clothes (especially double-sided clothes), pockets, bags, shoes (for example, boots, shoes), tents, mattresses, vehicles. Use an opening such as a seat.

In the above embodiment, the zipper made of a resin-made sprocket has been described. However, in the present invention, the type of the sprocket is not limited. For example, a single fastener element represented by a metal fastener element and a resin fastener element obtained by injection molding on a tape, and a continuous fastener element represented by a loop-shaped resin fastener element can be used without limitation. Further, the type of the zipper is not particularly limited, and the present invention can be applied to a stopper product with a lower stopper, a separate product with a detachable insert, and can be pulled apart from the side of the detachable insert. The reverse type of the zipper is inserted in such a manner that the guiding columns of the two sliding members are oppositely aligned to the head alignment of the element rows, so that the engaging sides of the two sliding members are inserted into the chain. All types of zippers, such as the end of the row of teeth.

Next, a preferred embodiment of the structure of the chain cloth which can be used in the present invention will be described in detail with reference to Fig. 8. The tape members (102, 103) constituting the chain cloth (101) respectively include a element attaching portion (201) and a tape main body portion (202). The sprocket mounting portion (201) is a portion of the sprocket row (104), and the tape main body portion (202) is sewn to the body of the article. Part of it. Further, the chain cloth (101) may further include a selvage portion (203) in which the side yarn portion for the anti-scatter yarn is provided on the side edge portion of the tape main body portion (202). A core cord portion for mounting the sprocket or the metal sprocket may be provided along the longitudinal direction of the chain in the sprocket mounting portion (201).

In order to dye the pattern or the like on the surface of the chain cloth, it is preferable to use a relatively fine yarn as the yarn constituting the tape member (102, 103). By using a finer yarn, the surface of the surface becomes smaller and smaller, so that a fine pattern can be exhibited. Therefore, it is preferable that the fineness of each yarn is 120 dSt or less, more preferably 110 dSt, or less, and even more preferably 100 dSt. However, if the yarn constituting the tape member (102, 103) is too thin, a tape member having sufficient strength cannot be obtained. Therefore, it is preferable that the fineness of each yarn is 50 dtex or more, more preferably 55 minutes. Above the taxi, it is better to be 60 points or more.

The yarn may also be any one of a monofilament fiber and a multifilament fiber, and one yarn may also contain a monofilament fiber, or may comprise a multifilament fiber obtained by bundling two or more monofilament fibers, or may be more Contains a plurality of multifilament fibers. For example, a yarn comprising two multifilament fibers obtained by bundling 50 filaments of 5dTex is one yarn of 500dTex.

The chain cloth can be produced, for example, by weaving or weaving, but it is preferable to perform weaving insofar as the surface of the tape after the production becomes flatter. In the main body portion (202) of the previous chain cloth, the ratio of the number of warp yarns constituting the plain weave to the total number of warp yarns is preferably about 10 to 40%. This is because the plain weave is a structure in which the warp and the weft are alternately alternated one by one (that is, a fabric having a warp of 1/1), and the warp and weft are interlaced, so the strength (tolerance of the warp in the width direction) The strength of the off-line which is shifted or the weft is shifted in the longitudinal direction) or the durability is excellent, but the texture is not exhibited. However, since the unevenness of the surface of the cloth tape becomes small, it is possible to display a detailed pattern and the like. Further, since the stretch of the chain cloth is small, the plain weave structure is advantageous from the viewpoint of the positional accuracy of the dyeing. Moreover, if a fine yarn is used, it is rich in flexibility even as a plain weave, and even if the ratio of the plain weave is raised, the texture is not greatly impaired. Therefore, even if the strength and the positional accuracy of the dyeing are improved by increasing the ratio of the plain weave, the deterioration of the texture can be suppressed. Therefore, in the present invention In the chain cloth (101), it is preferable that the yarn constituting the main body portion (202) of the tape has a ratio of the number of warp yarns constituting the woven fabric of 1/1 to the total number of warp yarns being set to 50%. More preferably, it is 60% or more. However, if there are too many plain weaves, the texture is too thin to sufficiently exhibit the texture. Therefore, with respect to the yarn constituting the main body portion (202) of the tape, the number of warp yarns constituting the fabric of 1/1 is relative to the total number of warp yarns. The ratio is preferably 80% or less, more preferably 75% or less.

As the woven structure for exhibiting texture, a woven fabric having warp yarns spanning two or more weft yarns, such as a twill weave or a satin weave, is preferable. As an example of the twill weave, in addition to the 2 warp yarns over the weft yarn, and then 2 2 pieces of the fabric structure (warp/weft) which sinks, 1/2 (also called 2/1), 2 / 2, 1/3 (also known as 3 / 1), 3 / 3, 4 / 4 and other fabrics, in terms of strength to withstand off-line, or texture, preferably 2/2 fabric . Therefore, in a preferred embodiment of the present invention, the tape main body portion (202) is woven with a combination of a warp yarn having a warp of 1/1 and a fabric structure of 2/2.

The tape main body portion (202) is woven in a combination of a fabric structure having a warp of 1/1 and a fabric structure of 2/2, and the texture is also increased by increasing the ratio of the fabric structure of 2/2, but if If the surface is excessively lifted, the unevenness of the surface becomes conspicuous, so that the texture of the texture and the smoothness of the surface (i.e., the positional accuracy of the dyeing) are simultaneously achieved. The number of warp yarns of the fabric of 2/2. More specifically, the ratio of the number of warp yarns constituting the woven fabric of 2/2 to the total number of warp yarns is preferably 20% or more (in other words, the ratio of the number of warp yarns constituting the fabric of 1/1 is 80% or less), more preferably 25% or more (in other words, the ratio of the number of warp yarns constituting the fabric of 1/1 is 75% or less). Further, the ratio of the number of warp yarns constituting the fabric of 2/2 to the total number of warp yarns is preferably less than 50% (in other words, the ratio of the number of warp yarns constituting the fabric of 1/1 exceeds 50%) More preferably, it is 40% or less (in other words, the ratio of the number of warp yarns constituting the fabric of 1/1 is 60% or more).

Here, the so-called warp yarn is 1/1 of the woven fabric, which means that one warp yarn passes over the weft yarn, followed by And a sinking fabric structure, the so-called warp 1/2 fabric structure refers to a warp yarn over the weft yarn, followed by two sinking fabric structure, the so-called warp yarn 2/2 fabric organization refers to 2 The warp yarn passes over the weft yarn, and then the two weaving fabrics. The so-called warp yarn is 1/3 of the fabric. It refers to one warp yarn that passes over the weft yarn, and then three sinking fabrics. The so-called warp yarn is 3/3. The woven fabric refers to the woven fabric in which three warp yarns pass over the weft yarn and then three sinks. The so-called warp yarn is 4/4 woven fabric refers to the fabric of four warp yarns over the weft yarn, followed by four sinking fabrics.

In the present invention, the weft yarn is regarded as two yarns and is regarded as one. Therefore, in Fig. 8, the woven fabric of A is a woven fabric having a warp of 1/1, and the woven fabric of B is a fabric of 2/2. However, the fineness of each yarn in the weft yarn refers to the fineness of one weft yarn before the yarn joining, and does not indicate the fineness in the state of two yarns. That is, the yarn of each yarn has a fineness of 120 cents, and the yarn of the two yarns is 240 cents in the state of two yarns, and the fineness of each yarn is 50 cents, and the yarn of two yarns is in the state of two yarns. Become a 100-point taxi. The reason for this is that a fabric having a narrow-length chain fabric in the longitudinal direction is produced by combining two weft yarns, and the reason is that the stretch of the chain fabric in the width direction can be withstood. In the example of the tape main body portion (202) shown in FIG. 8, the number of the warp yarns A constituting the plain weave structure for each of the ten warp yarns constituting the tape main body portion (202) is six, and The number of the warp yarns B constituting the fabric of 2/2 was four, so the ratio of the plain weave was 60%, and the ratio of the fabric of 2/2 was 40%. Further, the woven fabric structure which can be applied to the present invention is not limited to the description of the present embodiment, but the warp yarn adjacent to the warp yarn having the woven fabric of 2/2 indicated by B is left and right in the belt main body portion (202). A warp yarn having a fabric structure of 1/1 represented by A. The reason for this is to avoid the occurrence of irregularities on the surface due to the arrangement of two warp yarns having a fabric structure of 2/2.

On the other hand, in the element attaching portion (201), in order to increase the thickness and not to create a gap between the element and the tape, it is preferable to ensure the stability and the mounting strength of the mounting form of the element. The reason is that when the yarn constituting the tape member is made thinner, the thickness of the chain cloth becomes small, and thus Particularly effective. As a method of increasing the thickness of the element attaching portion (201), in addition to the thickening of the warp yarn used in the element attaching portion, a warp yarn obtained by joining two or more warp yarns to the element attaching portion may be used. In other words, in the element attaching portion (201), the unevenness of the surface is used to increase the thickness so as to arrange two or more fabric structures of 2/2 differently from the tape main body portion (202). In order to increase the thickness, it is preferable to increase the number of the yarns of the yam. However, if the number of the yarns of the yam is excessively increased, there is a problem that the detachment occurs or the tape becomes too thick. Therefore, the number of yarns of the yam included in one warp yarn row is preferably 2 to 4, more preferably 3. Further, it is preferable to prevent excessive flying of the yarn and offset of the woven fabric by one warp yarn which is arranged such that the woven position is shifted between the adjacent warp yarn rows.

As the raw material of the yarn for the chain fabric of the present invention, the previously used polyester, polyamide, polypropylene, acrylic, etc. may be used, but the material strength is high, and the dyeing after the manufacture of the chain fabric is also easy. In terms of color, polyester is preferred.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention.
