Description

Knitting Hidden Slide Fixture {KNITTED / WOVEN CONCEALED TYPE SLIDE FASTENER}

The present invention provides a continuous fastener element made of synthetic resin monofilament, in a fastener element mounting portion of a warp knitted fabric of warp knitted or woven structure provided with a fastener element mounting portion and a tape body. The invention relates to a knitted insertion hidden slide fixture in which the respective engaging heads of the rows are directed toward the fixture tape main body and are incorporated or incorporated in sequence simultaneously with the knitting or knitting of the fixture tape, in particular a hidden slide fixture using flexible fixture tape. A simultaneous knitting insert slide fixture of an element by knitting or weaving in which the element engagement portion is not visible from the outside and at the same time does not occur to release the engagement even against the strong bending or lifting force applied to the fixture. will be.

The hidden slide fastener includes a method of attaching a fastener element by sewing or molding to a fastener element mounting portion formed in a side edge portion of a fastener tape prepared by knitting or knitting in advance, and installing the fastener element simultaneously with the knitting or straightening of the fastener tape. It is a method of incorporating or indirectly fixing a series of fastener elements in a continuous state of synthetic monofilaments.

For example, the incorporating hidden slide fastener is fitted with a monofilament made of a synthetic resin monofilament formed by pre-engaging heads by stamping at the time of knitting a warp tape having a fastener element mounting portion and a tape body portion by pulling the upper and lower portions on the fastener element mounting portion. By inserting the weft continuously in the state, it is manufactured by incorporating the continuous urea string into the fixture tape.

In the case of the usual integrated slide fasteners, the connecting fastener elements are arranged so that each engaging head is projected outward from the outer end edge of the fastener element mounting portion, and the connecting portions connecting the upper and lower legs are disposed at the boundary with the tape body portion. In the case of an incorporating hidden slide fastener, for example, as disclosed in Japanese Patent Application Laid-Open No. Hei 8-22813, the engaging head of the fastener element is arranged along the bend region, which is the boundary between the tape main body part and the fastener element mounting part. In addition, the connecting portion is disposed and incorporated along the edge of the outer end of the fastener element mounting portion.

In this way, the stringer of the hidden slide fixture obtained by knitting is folded along the bending area so as to be exposed to the outside so that the stringer is set and the bending shape is fixed. The fastener chain is created by engaging the fastener elements of the left and right stringers with the bent shape, and the slider for the hidden slide fastener is passed through the fastener chain. Hidden slide fasteners are made. This hidden slide fastener prevents the fastener element rows from being visible from the outside so that the fastener element rows are sewn into clothing and the like with the fastener element rows inward.

According to the above-mentioned Japanese Patent Application Laid-open No. Hei 8-228813 (Patent Document 1), in particular, FIGS. 24 and 25 and its corresponding description, the upper and lower legs are reciprocated in the same course of the monofilament forming the coil-shaped fastener element string. The upper and lower parts of the fastener element mounting portion on the inner edge side of the fastener element mounting portion, and the connecting portion is placed on the outer edge side of the fastener tape and pressurized by three fixing chain knitting yarns 10 forming the upper and lower legs in a double structure. At the same time as the knitting of the tape, a coil-like fastener element array is fixed to the fastener element mounting portion.

On the other hand, as a direct hidden slide fixture, it is disclosed by Unexamined-Japanese-Patent No. 2-132419 (patent document 2), Unexamined-Japanese-Patent No. 2-283306 (patent document 3), and Unexamined-Japanese-Patent No. 9-234103 (patent document 4). Any of the monofilaments made of a synthetic resin in which a pre-engagement head is molded at the same time as the knitting of the fastener tape having a woven structure are continuously inserted into the fastener element mounting portion of the fastener tape.

However, in the above-described knitting insert slide fastener, the fastener element is sewn, added and manufactured or molded to be fixed to the element mounting portion of the fastener tape by molding, and the fastener tape element installation portion usually has a center strap. There are many things that we do not do. This center strap is incorporated or incorporated by inserting in the direction passing the side edge of the element mounting portion when forming the fastener tape. In this way, the integrated or indirect center strap is pressed between the upper and lower legs of the fastener element to secure each element to the fastener tape so that the fastener element does not fall out of the fastener tape.

If the knitting insertion hidden slide fixture is to be incorporated or directly incorporated into the center strap in the fixture tape, for example, as disclosed in Patent Document 4, a special mechanism for incorporating or incorporating the same center strap is required. This structure makes the structure more complicated. In addition, this kind of knitted hidden slide fasteners have been developed to improve fashion without deteriorating the appearance of outerwear and the like, and in recent years, they have been widely used for thin fabrics with abundant flexibility. In order to sew a knitted slide hidden fastener to this thin fabric, the fastener tape itself is made thin and flexible, and the gap between the upper and lower leg portions of the fastener element itself is eliminated, and if possible, the close slide between the upper and lower leg portions is possible. It is preferable because the entire fixture is thinner. By the way, the existence of the center strap is against this demand.

In addition, in the case where the center strap is excluded, the fastener element is fixed only by an element fixing warp knitting yarn or a stiff yarn disposed in the element mounting portion, and as mentioned above, the installation position of the fastener element is changed on the fastener tape and the engaging head The position changes easily in the tape axial direction of the fixture tape. For this reason, the alignment position of the engaging head is likely to be uneven. This is a fatal flaw in the hidden slide fixture whose mission is to make the engagement state between the engaging heads invisible from the outside of the adherend when the slide fixture is closed.

On the other hand, this type of hidden slide fastener is sewn to the adherend, and in the case of the embedded hidden slide fastener, it is formed between the bends of each of the fastener element rows of the left and right stringers, for example, between two wales adjacent to the engaging head side of each fastener element row. In the direct-hiding slide fastener, which is sewn along the groove, the adherend is formed along the bent portion of each fastener element row of the left and right stringers, such as a plurality of warp yarns adjacent to the engaging head side of each fastener element row. Is sewn on.

In this way, the stringers of the left and right slide fasteners are in the sewn and sewn by the service. When the slide fastener is in the closed state, the strings of the left and right slide fasteners are pulled strongly in the direction of disengaging the left and right slides. The ring positions of the left and right servings are changed in the direction of detaching from the weft (weft) between the warp yarns in the sewing position between the left and right grooves of the left and right stringers of the slide fasteners which are sewn, and the left and right adherends and A gap is created between the stringers, and the engaging head of the fastener element is often visible from the outside.

SUMMARY OF THE INVENTION The present invention has to solve the above-mentioned problems, and a specific object of the present invention is in a hidden slide fastener in which a fastener element is incorporated or directly inserted, in addition to connecting at the same time when the fastener tape is knitted or knitted, and at the time of closing the slide fastener. It is to provide a hidden slide fastener in which the engaging portion of the fastener element rows from the adherend is not visible from the outside, especially a thin and flexible fastener tape, and functions as a hidden slide fastener capable of securing the installation strength of the element on the fastener element side. Is to provide a fully equipped hidden slide fixture.

Therefore, in order to make the fastener tape itself thin and flexible, it is usually based on the material of the component thread, but it is usually influenced by the thickness or structure of the component thread or by its knitted or woven structure, or a fixture The influence of the knitting degree and the density of the tape is large. Moreover, even if these are selected properly, there is no guarantee that the required mounting strength of the fastener elements will be obtained. To obtain sufficient mounting strength of the fastener element, the clamping force of the fastener element by the warp yarn or stiff yarn (fastening thread) for fastening the element incorporated or directly incorporated into the fastener element mounting portion of the fastener tape of knitted or woven tissue Need to be increased.

In particular, in the knitted hidden slide fixture to be the object of the present invention, in order to obtain a thin, flexible and at the same time to obtain the installation strength of the fastener element is used within the range allowed as the warp yarn or rigid yarn for fixing the element used herein You must make thickness of degree. In general, the reason why the slide fixture is made flexible and thin is that, as already mentioned, when the adherend itself for installing the slide fixture is flexible and thin, the slide fixture needs to be familiar with the adherend during sewing and after sewing. For this purpose, the flexibility required for the slide fixture is particularly required for the tape body portion in the fixture tape. Of course, the flexibility of the fastener element installation itself is also desirable, but the fastener element installation part itself is necessary because there is a fastener element with a certain degree of rigidity and it is necessary to engage these fastener elements so that they do not easily fall out. If the flexibility of the acceptable range is satisfied, it cannot be satisfied.

Contrary to this general requirement, in particular the knitted hidden slide fasteners are urgently required to ensure that the engaging portions of the slides are not visible from the outside when using an article of attachment of the same slide fastener. However, in order to make the entire slide fixture thin and flexible, when the thread is used for all the components of the slide fixture, it is difficult to secure the necessary installation strength for the fixture element as described above, and at the same time, the position of the element to the fixture tape When the to-be-adhered body is pulled horizontally, the bending position of the fastener tape tends to be changed, and the left and right to-be-adhered body and the sewing parts of the fastener tape are extended to the left and right, and a gap is created. The engaging portion of the slide fixture is easily visible from the outside.

In light of this, the present inventors have repeatedly reviewed the results, and in particular, in the knitted hidden slide fixture having no center strap, even if it is not necessarily bound to be thin and flexible, a fastener for fixing the fastener element or a fastener by a weft yarn The degree of covering of the element, the structure and thickness of the fixing warp knitting yarn or the yarn of the rigid yarn, or the knitting structure of the tape bending area at the boundary between the element installation portion of the fastener tape and the tape main body portion, and the use of the yarn, can be applied to the adhered product of the slide fixture. Even when using it, I noticed that the engagement head ends without exposing it from the outside.

The basic construction of the present invention is characterized by the degree of coverage of the fastening warp knitting yarn or the warp yarn of the fastener element. That is, the engaging head portions of a series of fastener elements in a continuous state of monofilament made of synthetic resin are directed toward the fastener tape main body side at the fastener element mounting portion of the knit fastener tape having a fastener element mounting portion and a tape body or a knit structure having a woven structure. A knitted hidden slide fixture which is incorporated or incorporated in sequence simultaneously with the knitting or knitting of the fastener tape, and which is incorporated into or incorporated into the fixture element mounting portion to secure each element of the fastener element string in the continuous state to the fixture element mounting portion. A plurality of fixing threads are provided, and an exposed portion of each element covered by each fixing thread of the fastener element rows is an engaging head, and the distance from the distal end of each engaging head to the inner surface of the connecting portion is (a). Direction of legs covered by thread for fastening elements If the dimension (b), characterized in that value is greater than 1/2 4/5 or less of (b / a).

In this way, the exposed portion of each element covered by each fixing thread of the fastener element row is a distance (a) from the distal end of each engaging head to the inner surface of the connecting portion, and in the leg direction covered by the fixing thread of the element. In the case of the dimension (b), when the value of (b / a) is set to be larger than 1/2 and 4/5 or less, lateral attraction is applied to the adhered product of the hidden slide fixture, For example, even if a gap is formed, since most of the upper leg surface of each element is covered by each fixing thread, the engaging portion of the fastener element at its tip is also hidden by their fixing thread and is not exposed to the outside.

In the article of this type of knitted hidden slide fixture, the sewing portion of the slide fixture with respect to the adherend is the bent portion of the same slide fixture, and the element installation side of the fixture tape and the outer surface of the end edge portion of the adherend. Warp knitting (wale) or stiffness of the tape body portion overlapping the surface of the opposite edge portion and adjacent to the warp knitting yarn (Wale) of the tape main body portion closest to the fixing thread of the element mounting portion or adjacent to the warp yarn or the warp yarn group same as the warp yarn group. It is the part of the groove between the four soldiers or the part of the weaving army.

At this time, the thread for fixing is at least two or more, and it is preferable to fix it in two or more parts in the longitudinal direction of the upper and lower leg portions of the fastener element, and it may be constituted by a pair of threads in which two fixing thread units are drawn. It may be. Thus, by using a pair of threads in at least two or more fixing threads and the same fixing thread itself, the tightening force by the fixing thread to the fastener element can be widely distributed in the longitudinal direction of the upper and lower leg portions. This becomes more stable and stronger. In addition, if the exposed portion of the surface of the upper leg of each element covered by each fixing thread is less than 1/5 from each engaging head end to the connecting end, the fixing thread and the slider interfere with each other and the sliding operation of the slider is prevented. This is undesirable because it is easy to interfere and may interfere with the smooth engagement of the interlocking heads.

In the present invention, it is preferable that the total thickness of two or more fixing threads covering the upper leg surface of each element has a thickness of 1.5 to 5 times that of the other component threads of the fastener tape. As mentioned above, the flexibility required as a whole of the slide fixture is determined by the tape body portion, and the flexibility of the element mounting portion in which the fixture element is installed is inevitably sacrificed to some extent to secure the engagement strength of the fixture element. When the fixing thread is set to 1.5 to 5 times that of other constituent threads of the fastener tape, the fixing can be secured by the fastening, so that element shift can be eliminated even if no center strap is present. If the thickness is less than 1.5 times that of the other component threads of the fastener tape, the coverage for the fastener element becomes difficult to obtain; if it exceeds 5 times, the coverage for the fastener element is obtained, but the tape installation including the fastener element for the tape body is obtained. The thickness of the part becomes too thick and loses balance with the adherend, and the contact portion with the body becomes hard, causing discomfort.

As already said, with this type of hidden slide fastener, the use of the knitting structure of the tape bending area, which is the boundary between the element mounting portion of the fastener tape and the tape body portion, and its thread are installed on the slide fastener mounting portion in the fixture attachment product. It plays an important role in preventing the engaging portion of the fixture element string from being seen from the outside. In the present invention, it is preferable that at least one warp yarn in the bent portion of the fastener body portion adjacent to the engaging head row of the fastener element rows is composed of a composite filament and the short fiber fineness of the constituent filaments of the warp yarn is set to 0.5 to 1.5 dTex. Do. The short fiber fineness of the constituent filaments of the warp yarns used in the bent portion of a conventional hidden slide fixture is about four times the fineness of the present invention, that is, the number of the constituent filaments is about 1/4 It is a relatively hard movement.

In the present invention, by using a single fiber fine fiber as described above, it has a plurality of filaments which are extremely thin and flexible, and is used as warp yarns used in the aforementioned bent portion of the hidden slide fixture. Such warp yarns made of a plurality of filaments are more flexible than the conventional ones, so that the warp yarns of the bent portion also increase the volume of the entire bent portion formed by the same warp yarns. Even if there is a gap in the left and right sewing portions, the left and right warp portions of the bent portion do not fall, and the portion of the engaging head of the slide fixture is concealed from the outside.

At the same time, it is preferable that the total thickness of the warp yarns in the bent portion of the fastener tape body portion adjacent to the engaging head row of the fastener element is set to be thicker than the thickness of the other yarns forming the branch structure of the fastener tape. If the total thickness of the warp in the bent portion is set to be thicker than the thickness of the other thread constituting the paper tissue of the fastener tape, the left and right warp portions of the bent portion when the gap is formed in the left and right sewing portions of the adhered product of the hidden slide fixture Contact is maintained and the engagement portion of the slide fixture is concealed from the outside.

In the present invention, it is preferable that at least a part of the wefts constituting the tape main body portion adjacent to the same mounting portion as the element mounting portion of the fastener tape has a dry heat shrinkage ratio of 8 to 20% higher than that of the other component threads of the fastener tape. The weft, which constitutes the branch structure of a part of the fastener tape, also has a function of fastening the fixing warp of the fastener element disposed in the element mounting portion. For example, in the incorporating hidden slide fixture, most of the tape main body portion has a common thread having a low dry heat shrinkage ratio and constitutes a weft yarn, but in the present invention, in particular, the tape main body portion disposed on the urea mounting portion and the same mounting portion is disposed. It is preferable to use yarn with high dry heat shrinkage between the composite filaments having 1.5 to 4.0 dTex of single fiber fineness in the gastric insertion yarn. In the case of the direct hidden slide fastener, not only the element mounting portion but also a thread having a large dry heat shrinkage ratio is used for some of the wefts over the entire width of the fastener tape. With this arrangement, the dry weft yarn (weft inserting yarn) having a high dry heat shrinkage ratio at least draws the fixing warp of the element disposed at the element mounting portion to the paper tissue and tightens the same element firmly.

In addition, in the present invention, all other components of the fastener tape except the fixing warp and the weft of the element are made of a plurality of filament yarns with little twist, and the single fiber fineness of each filament yarn is 0.5 to 1.5 dTex. In some cases. By employing this configuration, removing the element mounting portion of the slide fixture ensures the flexibility and flexibility in the longitudinal direction of the fixture tape. Moreover, the short fiber fineness of each component filament of the weft which is a part of the component yarn of the said tape main-body part may also be 0.5-1.5 dTex. By such a configuration, flexibility and flexibility in the width direction are secured not only in the longitudinal direction of the fastener tape.

The fastener tape becomes a warp knitting structure, and the total thickness of the warp knitting yarn used for the fastener warp, for example, chain knitting yarn, tricot knitting yarn, two-neck knitting yarn, or a combination thereof, and constituting a wale disposed on the most tape main body side. It is preferable that it is set thicker than the other constituent knitting yarns of the paper tissue except the fixing warp knitting yarn. Normally, this type of hidden slide fixture is along a groove formed by a weft between the warp yarns of the tape main body portion adjacent to the same wale as the warp knitting yarn constituting the wale disposed adjacent to the tape main body portion side of the fixing warp with respect to the adherend. It is sewn and simultaneously bent along the adherend along its seam.

The concealed slide fixture thus obtained conceals from the outside the engagement portions of the left and right stringers in contact with the left and right wales arranged adjacent to the main body side of the fixing weft. At this time, if the same wales have the size required, even if the left and right adherends are pulled to the left and right, the left and right wales are less likely to fall and the engaging portions are hardly seen from the outside. As described above, when the thickness of the warp knitting yarn used for the left and right wales is thickened, the size of the same wale is naturally increased, and the concealing function of the element engagement portion is effectively exhibited. The thickness of the warp knitting yarn used for the left and right wales at this time refers to the thickness of the knitting yarn itself constituting the needle ring arranged in the same wale.

The knitting yarn constituting the wale closest to the fixing warp knitting yarn and knitted in the tape main body portion is two kinds of weft inserted yarns which are folded left and right in the course direction in the same wale with at least two types of warp knitting yarns and at least in the same horizontal direction It is preferable that the above interbed yarn has a dry heat shrinkage ratio of 8 to 20% higher than that of other constituent knitting yarns of the same wale. The groove portion formed between the wale of the tape main body portion adjacent to the wale such as the wale is a sewing portion sewn with serving to the adherend.

Therefore, when the hidden slide fastener and the adherend are sewn and bent, the left and right wales closest to the fixing warp knitting yarn and knitted on the tape main body portion are in a state of being in close contact with each other. As described above in this wale, when two or more types of warp knitting yarns and two kinds of weft inserts folded in the course direction in the same wale are used, the same wale becomes large so that the element is not easily seen from the outside when the element is engaged. In addition, since the yarn which maintains a dry heat shrinkage rate of 8 to 20% higher than other component knitting yarns is used as the left and right weft inserting yarns constituting the same wale, the same knitting yarn forming the same wale during dry heat setting is used. Since the needle ring is fastened from the left and right, the groove shape formed between the wales of the adjacent tape main body portion becomes clear, and the sewing operation at the time of sewing is facilitated.

Further, in the present invention, it is preferable that the fixing warp knitting yarn is composed of chain knitting yarns, and the needle ring is hooked on the upper surface of the upper leg portion of the fastener element, and the sinker ring is connected to the paper tissue. Because of this, not only the fastening force for the fastener element is strong, but also the covering degree for the fastener element can be increased, and the installation strength of the element is increased, and it becomes less visible from the outside.

Furthermore, it is preferable to simultaneously use two types of chain knitting yarns, tricot knitting yarns, or two-neck knitting yarns for knitting yarns which constitute the wale closest to the fixed warp knitting yarn and knitted in the tape main body portion. Since the tricot knitting and the two knitting yarns have the function of forming the wale and at the same time connecting the wales, the tricot knitting yarn and the stapling knitting yarn also have a function of fixing the fastener element together with stabilizing the knitting shape. Therefore, by using these knitting yarns together with chain knitting yarns, not only the fastening force on the fastener elements can be strengthened, but also the coverage of the upper legs of the fastener elements can be increased, and the shape of the grooves between adjacent wales can also be stabilized.

The integrated hidden slide fixture of the present invention has one row of needles and is knitted by a warp knitting machine such as, for example, a Russell knitting machine, and as shown in Fig. 2, the branch structure of the tape main body portion A is 1. Zigzag pattern over -0 / 0-1 chain knitting yarn (1), 1-2 / 1-0 tricot knitting fabric (2), and 3 wale (W) of fastener tape (4) It consists of 0-0 / 3-3 gastric interstitial yarn 3 inserted. In addition, the element mounting portion B consisting of three rows of wales W1 to W8 at the long side edges of the pair of left and right fastener tapes 4 and 4 'excludes the tricot knitting yarn of 1-2 / 1-0. Two rows of wales W4 of the tape main body 11 of 1-0 / 0-1 and the tape main body portion A adjacent to the three wales W1 to W8 of the fastener tape 4 and the wales W3; The fastener tape 4 similarly intersects with the 0-0 / 3-3 gastric insertion thread 12 inserted in a zigzag pattern and the same gastric insertion thread 12 which does not exist in the tape body portion A. It consists of 2-2 / 0-0 inverted interstitial yarns 13 of 2-2 / 0-0 which are inserted in a zigzag shape respectively over two wales W1 and W2 and W3 and W4.

Incidentally, the knitting structure is not limited to the structure shown in Figs. 1 to 3, and for example, fixing chain knitting yarns constituting the wales W2 and W2 of the element mounting portion B of the fastener tape 4. In the needle ring of (11), a light insertion yarn having a structure of 0-1 / 1-1 as shown in Fig. 2 is vertically incorporated in a zigzag pattern, and a 2-2-0-0 yarn knitting yarn is incorporated. Alternatively, the knitting structure of the gastric insertion yarns 3 and 12 is set to 0-0 / 4-4, and the knitting structure of the reverse gastric insertion yarn 13 is set to 3-3 / 0-0. Alternatively, the knitting body 12 of the urea mounting portion B and the knitting structure of the reverse insertion yarn are 0-0 / 3-3 and 2-2 / 0-0 shown in FIG. ) Can be modified as appropriate, such as 0-0 / 4-4.

On the other hand, a synthetic resin made of nylon, polyester, or the like, which pre-configures a connecting portion Ec for connecting the engaging head Eh constituting the coil-shaped fastener element array ER and adjacent upper and lower leg portions El1 and El2. The monofilament 5 extends over the two wales W2 and W3 adjacent to the wale W1 disposed at the outermost side of the element mounting portion B, and the engagement head Eh is attached to the tape body portion ( With connection to A), the connecting portion Ec is directed outward of the element mounting portion B, and travels in a reciprocating motion in the direction intertwined in the same course while skipping one course C, and FIGS. 1, 3 and As shown in Fig. 4, the upper and lower leg portions El1 and El2 of each fastener element E are 1-0 / 0-1 in the two wales W2 and W3 constituting the branch structure of the element mounting portion B. Knit by pressing the needle ring of the two fixing chain knitting yarns (11, 11) of the To and incorporated by connecting a column (ER) fastener element.

Stringer (S) according to the present embodiment having such a knitted structure is a fastener tape (4) is bent in a U-shape by setting the fastener tapes (ER) to the outside along the bending line (L) shown in Fig. do. For example, in the present embodiment, the bending portion D is bent along the wale W4 of the tape body portion A that is closest to the element fixing wale W3 on the tape body portion side of the element mounting portion B. And sewn to serve as the adherend along the groove C formed between the wale W5 of the tape main body portion A adjacent to the same wale W4. In Fig. 3, each of the knitting yarns 1 to 3, 11 to 14 is shown as the same size and single thread, and the knitting of the needle rings and the like is loosened. In practice, each knitting yarn is considered to function as a built-in slide fixture, and the size and number of configurations are appropriately selected, and the knitting is also closely finished.

According to the present embodiment, all the knitting yarns 1 to 3, which constitute the fastener tape 4, are fixed to the fastening chain knitting yarns 11 and 11 of the two wales W2 and W3 arranged in the element mounting portion B. 12, 13). The fixing chain knitting yarns 11 and 11 do not have any problems with composite filament yarns or twisted yarns. Incidentally, in the present embodiment, two twisted yarns composed of two composite filaments are pulled and used together in one anchoring chain knitting yarn 11, and the thickness of each composite filament yarn is 165 dTex, and one anchoring chain knitting yarn is used. The total thickness of 11 is set to 165 x 2 (330) dTex. The total number of filaments of the fixing chain knitting yarn 11 according to this embodiment is 72, and the short fiber fineness of the constituting filaments is not changed from the conventional one.

By using such fixing chain knitting yarn 11, not only the installation strength of the element can be secured with respect to the fixing element knitting element E, but also the needle ring of the fixing chain knitting yarn 11 By tightening firmly over the upper leg El1, the same fixing chain knitting yarn 11 is flattened to extend the upper surface of the upper leg El1 in the longitudinal direction, and the majority of the same upper leg El1 is extended. Cover. The coating degree at this time is a portion in which the surface of the fastener element E is exposed to the outside when it is covered by the fastening chain knitting yarns 11 and 11, respectively. The exposed portion of each element E covered by 11) is the engaging head side, and the distance from the tip of each engaging head E to the inner surface of the connecting portion Ec is (a), and the fastener element ( When the distance of the dimension of the leg part E side covered by the fixing chain knitting yarns 11 and 11 of E) is set to (b), the value of (b / a) is larger than 1/2 and is 4/5 or less. It is necessary.

If the numerical value of (b / a) is smaller than 1/2, even if the slide fixture provided on the adherend is pulled by the normal force in the direction in which the engagement of the element is pulled out along the fixture tape 4, the element is removed from the gap. The engagement part is easily seen from the outside. If the value of (b / a) exceeds 4/5, each of the fixing chain knitting yarns 11 and 11 covers a part of the engaging head Eh and prevents the smooth sliding (sliding) operation of the slider. do.

On the other hand, the knitting yarns (chain knitting yarns 1 and tricot knitting yarns 2) of the majority (Wale W5, W6, ..., Wn-1) constituting the tape main body portion A in the present embodiment are the same. A single composite filament yarn of size is used, and the thinnest one is used as the constituent thread of the fastener tape 4 with each thickness being 84 dTex. The short fiber fineness of each filament unit of each composite filament yarn constituted by the chain knitting yarn 1 and the tricot knitting yarn 2 constituting most of the branched tissues is extremely thinly set to 0.5 to 1.5 dTex. Incidentally, the number of constituent filaments of one composite filament yarn used here is 72 pieces. On the other hand, a sublime processed yarn made of a composite filament is used for the gastric insertion yarn (3) constituting the branch structure, and its thickness is 110 dTex, which is slightly compared with the chain knitting yarn (1) and the tricot knitting yarn (2). It is set thick and the number of the constituent filaments is 48, which is smaller than the number of the constituent filaments of the other knitting yarns, and the short fiber fineness of each filament is increased. Rather, the chain knitting yarn constituting the wale W1 disposed on the outermost side of the element mounting portion B is also the same type of knitting yarn as the chain knitting yarn 1 of the tape main body portion A, and the tape main body portion A As for the chain knitting yarns constituting the wale Wn disposed on the outermost side of the), the same type of knitting yarn as the fixing chain knitting yarn 11 is used so as to retain the ear shape and strength of the end edge thereof.

Thus, the wale formed in most of the regions constituting the tape main body portion A is constituted by the chain knitting yarn 1 and the tricot knitting yarn 2 and the gastric insertion yarn 3, so that the total constituting each wale is formed. The thickness of the thread is 84 X 2 + 110 (= 278) dTex. In addition, the grooves between the thus formed wales are approximately 110 dTex thick because they depend on the fineness of the gastric insertion yarn 3. The tape main body portion B thus obtained is composed of a plurality of filaments having a single fiber fineness of about 1/4 of the conventional single fiber fineness, and in particular, since the gastric insertion yarn 3 is a sublime processed yarn, it is very flexible and soft. It becomes an outstanding thing.

By the way, in the present embodiment, the most characteristic portion in addition to the fixing chain knitting yarn 11 is the tape main body portion nearest to the element fixing wale W3 on the tape main body side of the element mounting portion B ( It is a groove structure formed between the wale W4 of A) and the wale W5 of the tape main-body part A adjacent to the same wale W4. The wales W4 of the tape main body portion A adjacent to the wales W3 for fixing the elements disposed on the tape main body portion side of the element mounting portion B are provided by the fastener tape 4 as shown in FIG. When bent along the curve L, as shown in Fig. 4, when the wales W4 and W4 of the left and right stringers S are separated from each other, the engaging portion of the fastener element E existing on the rear side therebetween comes from the outside. It becomes easy to see.

Therefore, in the present embodiment, in particular, even if a strong force is applied to increase the thickness in the direction of penetrating the tape of the wale W4, and temporarily engage the left and right element rows ER with respect to the hidden slide fixture, the wales W4 The close state of is maintained. Therefore, in the present embodiment, a thick knitting thread is used for the knitting yarns forming the same wale W4, and a knitting structure firmly tightened from the left and right to narrow the wale width is adopted.

In the present embodiment, the wale W4 is a tree of 1-2 / 1-0 that constitutes a chain knitting yarn 1 'of 1-0 / 0-1 and a branch structure of the tape main body portion A. 2-2 / 0-0 reverse weft yarn which is interlaced with the coat knitting yarn 2, the above-mentioned weft insertion yarn 12 of 0-0 / 3-3, and the same weft insertion yarn 12 It is composed of four kinds of 13). Incidentally, in the present embodiment, the chain knitting yarn 1 'is composed of two composite filament yarns having a thickness of 84 dTex, the total thickness of which is 84 x 2 (168) dTex, and the total number of filaments is 144. Comparing this with conventional filament yarns (168 dTex, 36 filaments) with the same thickness as conventional ones, it can be understood that the short fiber fineness of the constituent filaments is a very thin filament of conventional 1/4. Thus, by using a composite filament yarn made of fine filaments as the chain knitting yarn 1 'of the same thickness, the rigidity at the boundary between the element mounting portion B and the adjacent tape main body portion A can be reduced. And flexibility is ensured.

On the other hand, the weft insertion yarn 12 of 0-0 / 3-3 and the reverse weft insertion yarn 13 of 2-2 / 0-0, which are interleaved with the same weft insertion yarn 12, are each High shrink yarns with a thickness of 165 dTex and dry heat shrinkage of 8 to 20% are used. In addition, such filament yarn or ordinary twisted yarn using a filament having a normal short fiber fineness can be used for the gastric insertion yarns 12 and 13. In addition, the tricot knitting yarn 2 of the above-mentioned 1-2 / 1-0 uses the same kind of knitting yarn as the tricot knitting yarn 2 used for another tape main body part.

Moreover, in this embodiment, also about the wale W5 of the tape main-body part A adjacent to the said wale W4, the knitting of the paper structure which comprises another tape main-body part A (chain knitting 1, Tricot knitting yarns 2 and gastric insertion yarns 3) and some different knitting yarns are used. In other words, a composite filament yarn having a thickness of 110 dTex of 48 filaments is used for the chain knitting 1 " of the wale W5. The thickness of the composite filament yarn and the short fiber fineness of the constituent filaments are measured using a tape body portion ( Although thicker than the other chain knitting yarns 1 of A), they are thinner than the fixing chain knitting yarns 11 and thinner than the chain knitting yarns 1 'of the wales W4 adjacent to the element mounting portion B. The other constituent knitting yarns (tricot knitting yarns 2 and gastric insertion yarns 3) of W5) are no different from the corresponding knitting yarns of the wale W4.

On the other hand, according to the built-in hidden slide fastener according to the present embodiment having the above configuration, a composite filament yarn is used for the entirety of the fastener tape 4, and in particular, the element mounting portion B and a part of the above-mentioned interstitial yarn 12, 13 Since the whole of the fastener tape 4 for removing the filament tape is 0.5 to 1.5 dTex, a composite filament yarn made of very thin short fiber fineness is used, thereby obtaining a slide fixture having excellent flexibility and excellent softness.

In addition, in the element mounting portion A, a thick composite filament is used for the element fixing chain knitting yarn 11, and a gastric insertion yarn 12 and a reverse gastric insertion yarn 13 having a high dry heat shrinkage ratio are used, for example. The upper and lower leg portions El1 and El2 of each fastener element E can be tightened and fixed even if the center strap is removed, and the gastric insertion yarn 12 and the reverse gastric insertion yarn 13 which are greatly contracted by the dry heat set are provided. By tightening the element fixing chain knitting yarn 11 to the connecting portion (Ec) side of the upper and lower legs (El1, El2) of the fastener element (E) at the same time, the same element fixing chain knitting yarn (11) made of a composite filament After being sewn into the adherend to flatten and cover the upper surface of the upper leg El1, a strong lateral attraction acts temporarily on the left and right stringers S and the engaging portion of the fixture element row ER Even if exposed, the element (E) It makes it hard to see and fully secures the function as a hidden slide fixture.

In particular, in the present embodiment, the element attachment portion B is adjacent to the same wales W4 as the wales W4 of the tape body portion A adjacent to the element fixing wales W3 on the tape body portion side. The composite filament yarn thicker than the other strand knitting yarns 1 of the tape body portion A is used for the component knitting yarns of the tape body portion A and the wale W5, in particular, the chain knitting yarns 1 'and 1 ". Gastric insertion yarn 12 and reverse gastric insertion yarn which are excellent in dry heat shrinkability to be inserted into the element fixing chain knitting yarn 11 as the upper insertion yarn on the side of the element installation portion B folded into the wales W4 and W4 ( In order to use 13), the gastric insertion yarn 12 and the reverse gastric insertion yarn 13 are greatly contracted in the dry heat set, and both wales W4 and W5 are pulled and attached to the element installation part B side. As the cross section of (W4) is made large and the thickness is thickened, for example, the slide fastener blood of the adherend which sewed this hidden slide fixture, Even if a strong lateral attraction force is applied to the attachment to release the engagement of the connected elemental row ER, the left and right wales W4 and W4 which are in close contact with the bent portion D of the fastener tape 4 do not fall off from the outside. The engaging portion of the island element E becomes difficult to see.

Further, the cross-sectional shape of the wale W5 of the tape main body portion A adjacent to the same wales W4 as the wales W4 is formed larger than other wales of the tape main body portion A, and at the same time, such a wale W4. , W5) is tightly tightened with the gastric insertion yarn 12 and the reverse gastric insertion yarn 13, so that the thickness of each wale W4, W5 is thicker than that of the wale constituting the other branch tissue. When added, the service ring of the sewing thread is caught by the same wales W4 and W5, and it is not moved further, and the bending portion D of the fastener tape 4 is not opened wider than this, and the continuous element string ER is externally opened. Makes it harder to see. In addition, the shape of the groove formed between the wales (W4, W5) is also clearly expressed and the sewing work on the adherend becomes easy. The width of the grooves at this time is about 1 to 1.5 mm and is preferable since it does not cause gaps in sewing between the adherend.

Figures 5 and 6 show the upright structure rows of the continuous fastener element rows of the upright hidden slide fixture and the bending form of the hidden slide fixture, according to another exemplary embodiment of the present invention.

In the shown direct hidden slide fixture, the warp (inclined) groups arranged in the element mounting portion B are lower than the lower leg El2 adjacent to the upper surface of the upper leg El1 of each fastener element E. FIG. A pair of element tightening warps 21, 22; 23, 24; 25 intersecting between the group of element fixing warps 21 to 26 intersecting between the elements E smoothly contacting the surfaces with each other and the element E. , 26) and do not cross the upper surface of the upper leg El1 of each fastener element E of the element array ER up and down on the lower surface of the lower leg El2, and not in a straight line shape. 8 pairs of four pairs of jaws that fasten the upper and lower legs El1 and El2 of the element E up and down by two pairs of wefts 40 moving between the elements E so as to be enclosed between each element E. It is comprised by the warp thread 27-34 group for upper and lower element fixing.

The fastener element string ER is a monofilament made of a synthetic resin having a pre-engaged head Eh and a connecting portion Ec similarly to the incorporating hidden slide fastener of the above-described embodiment, and the engaging head Eh of the tape main body. To the part A, the connecting part Ec is placed on the outer edge of the element mounting part B, and the upper and lower leg parts El1 and El2 are parallel to the upper and lower parts, and are directly inserted in the same order as the knitting of the fastener tape 4. And is installed in the element mounting portion B of the fastener tape 4. In this embodiment, after each of the two pairs of wefts 40 are enclosed twice, each fixture element E of the fixture element row ER is enclosed.

Tape main body portion A in this embodiment is the end of the loop between adjacent weft yarns 40 formed at the edge side edge of the tape side opposite to the element mounting portion B from the warp yarn indicated by reference numeral 35-1 in FIG. Is composed of a plurality of warp groups up to the warp yarns 35-N adjacent to the entangled ear parts 41 intersecting with each other and the weaving yarns 40 in order. 5 and 6, the spacing between the warp yarns 21 to 35-N for weaving the fastener tapes, between the weft yarns 40, and the respective fastener elements E are largely shown so as to make the fabric structure clear. In practice, however, the spacing between the warp yarns 21-35-N and adjacent wefts 40 is more dense, and the pitch between each fastener element E is closer. Moreover, the direct hidden slide fixture provided with the above structure can be manufactured by the weaving method disclosed by the said patent document 4, for example.

The fixture stringer S having the above-described configuration is disposed on the side of the most engaged head Eh of the element string ER and moves on the lower surface of the lower leg El2 of each element E as shown in FIG. The fastener tape 4 is bent and the heat of the fastener urea ER is outward along the two warp yarns 35-1 and 35-2 of the tape body portion A adjacent to the urea fixing warp 32. The bent shape is fixed by the set. Engaging the engaging heads Eh arranged along the opposite side edges of the left and right pairs of fastener stringers S in the direct hidden slide fixtures thus obtained, the closest to the most engaging head Eh side of the element string ER. The portions (bending portions D) of each of the two warp yarns 35-1 and 35-2 of the tape main body portion A adjacent to the warp elements 33 and 34 for arranging the elements are brought into close contact with each other, and the outside Hides the element grips from them so that they are not visible.

Also in this direct hidden slide fixture, when required to secure the required mounting strength of the fixture element string (ER), and when installed on the adherend by sewing, if the adherend is sandwiched between the left and right stringers (S) in the horizontal direction Even if this is applied, the engaging portion of the fixture element row ER is not seen from the outside, so that the bent adjacent to the fixing and tightening warp yarns 21 to 32 and the same installation portion B of the element mounting portion B are It demonstrates centering on use of the warp threads 35-1 and 35-2 of the tape main-body part A arrange | positioned at the part D, and each thread of the said weft 40. FIG.

Also in this embodiment, the basic technical idea is the same as in the above embodiment shown in Figs. For example, at the same time using a thread thicker than the other threads constituting the fastener tape 4 in the fixing and tightening warp yarns 21 to 32, in particular, the tightening warp yarns 21 to 26 of the element mounting portion B, It is preferable to use a composite filament of a plurality of filaments having a thinner filament fineness in the same thread. By using such a thick composite filament, fixing and tightening warp yarns 21 to 34 for fixing and tightening each element E are flat on each element E, and the upper surface of the upper leg El1 is wide. At the same time, the upper and lower legs El1 and El2 can be brought into close contact with each other, and in the absence of a center strap, each element E does not slide in the axial direction of the tape, and the fastener element rows ER are attached to the element mounting portion B. Can be installed tightly on

Moreover, composite filament yarn is also used for the warp yarns 35-1 and 35-2 arrange | positioned at the bending part D of the tape main-body part A adjacent to the element installation part B. FIG. The thicknesses of the warp yarns 35-1 and 35-2 are thinner than the thicknesses of the fixing and tightening warp yarns 21 to 34, but are compared with those of the warp yarns 35-3 to 35-N constituting other paper tissues. Is set thicker. Furthermore, in the warp single fiber fineness of the warp yarns 35-3 to 35-N constituting each of the filaments constituting the warp yarns 35-1 and 35-2 disposed in the bent portion D and the other branch tissues, respectively. As in the above embodiment, an extremely thin filament in the range of 0.5 to 1.5 dTex is used. If the warp density is reduced here, the warp yarns 35-1 and 35-2 are tightened by the weft yarn 40, so that the thickness in the direction of penetrating the tape without flattening increases and the stringer S on the left and right sides is increased. The left and right warp yarns 35-1 and 35-2 in the same bent portion D are strongly adjacent to each other when the fastener elements E of the two sides are engaged with each other. Even if a lateral attraction force is applied to S), the warp yarns 35-1 and 35-2 are less likely to fall, and the engaging portion of the fixture element row ER is not seen from the outside.

To further ensure this function, at least a part of the weft 40 has a thread with a high dry heat shrinkage ratio and a large shrinkage occurring when setting dry heat to bring the tightening warp yarns 21 to 26 into close contact with each other. It is preferable to tighten and fix the warp yarns 27 to 34 at the same time and tighten the warp yarns 35-1 and 35-2 disposed at the bend portion D to meet each other. However, because of its manufacturing method, it is difficult to change the type of weft yarn in the tape width direction, so that, for example, a yarn having a high dry heat shrinkability may be used for the weft yarn 40 and shrink in the tape width direction, but the dry heat shrinkage rate in the tape length direction is high. It is also possible to disperse yarns and yarns with low dry heat shrinkage. When weft yarns with different shrinkage rates are used, yarns with a low dry heat shrinkage rate, for example, using a new yarn using woolly processing, can easily follow the heat shrinkage behavior of yarns with a high dry heat shrinkage rate even if yarns with a low dry heat shrinkage rate are used. In addition, a slide fixture with excellent overall flexibility and soft feeling can be obtained.
