Description

  The present invention relates to a fastener, and more particularly, to a male fastener that is paired with a female fastener.

The male surface fastener is configured as a hook hook by forming the tip of the pile fabric into a J shape, or as a mushroom hook by forming a molten mass at the tip of the pile (for example, Patent Documents 1 and 2). reference). A needle punching nonwoven fabric in which a surface fluff is heated to form a mushroom hook on the fluff tip is known as a substitute for a male surface fastener (see, for example, Patent Document 3). The female surface fastener is a kind of loop pile fabric, and the loop pile acts as a female hook that engages with a hook-shaped hook or a mushroom-type hook. It is known to substitute a needle punched nonwoven fabric with raised fibers for a female surface fastener (see, for example, Patent Document 4).
Japanese Patent Publication No. 57-12603 (Japanese Patent Laid-Open No. 56-45602) (FIGS. 1, 2 and 3) JP-A-60-24801 (FIG. 2). Japanese Utility Model Publication No. 60-24236 (Japanese Utility Model Publication No. 58-80080) (Claim 5, FIG. 2, FIG. 4, FIG. 5). Japanese Patent No. 2971332 (JP-A-8-27657) (Claims).

  Forming a J-shaped hook-shaped hook or a mushroom-type hook (hereinafter, these hooks are collectively referred to as a male hook) at the tip of the pile of the pile fabric requires a high level of technology and cannot be easily formed. . For this reason, male surface fasteners (hereinafter referred to as male fasteners) are extremely expensive compared to female surface fasteners (hereinafter referred to as female fasteners) that can substitute loop pile fabrics and nonwoven fabrics. is there. The method of forming the male hook by heating the surface of the needle punching nonwoven fabric is a kind of fizzing treatment that burns off the fluff on the surface of the fabric. As described in Patent Document 3, the back surface of the carpet is applied to the anti-slip treatment. However, depending on the method, it is impossible to form a male hook having a uniform shape.

  Since normal loop pile fabric and non-woven fabric can be used for female fasteners, if there are double-sided male fasteners with male hooks protruding on both front and back, conventional single-sided male fasteners can be sewn or bonded Even if it does not, it becomes possible to join two kinds of fabrics such as loop pile fabrics, non-woven fabrics, or loop pile fabrics and non-woven fabrics, by simply sandwiching the double-sided male fastener. However, such a double-sided male fastener is not known. Therefore, even when loop pile fabrics or non-woven fabrics or loop pile fabrics and non-woven fabrics are joined, a conventional single-sided male fastener is attached to one of the fabrics, or two single-sided male fasteners are bonded together. Thus, a double-sided male fastener is prepared.

  In the prior art, the tip of each pile fabric is processed into a J-shaped or mushroom-shaped male hook, and the base fabric is densely woven to make the pile stand upright. In the pile, a thick monofilament yarn exceeding 100 dtex is used. For this reason, in the prior art, a soft and flexible single-sided male fastener with a thin base fabric and a soft male hook cannot be obtained. In the conventional male fastener, the male hook is composed of a thick, hard monofilament thread. Therefore, when repeating the joining and peeling with the loop pile fabric, the fiber of the loop pile is scraped to the male hook, and the loop The pile surface of the pile fabric is unraveled and fluffed, and the appearance is impaired. For this reason, monofilament yarn exceeding 100 dtex must be used also for the loop pile (female hook) for the female fastener, and as a result, the female fastener is also hard and uncomfortable. For this reason, when the conventional male fastener and the female fastener are attached and the two pieces of fabric are joined, the attachment portion swells abnormally and the appearance of the fabric is impaired.

  Accordingly, a first object of the present invention is to easily obtain a male fastener in which a male hook is densely formed. The second object of the present invention is that the male hook is formed of fibers of less than 100 dtex, and the pile surface is fuzzy and worn in repeated joining and peeling with a loop pile fabric composed of fibers of less than 10 dtex. There is no male fastener to get. The third object of the present invention is to obtain a soft and flexible male fastener that is used for joining fabrics and does not impair the feel of the fabrics. The fourth object of the present invention is to provide a simple double-sided male fastener that can be sandwiched between a loop pile fabric and a loop pile fabric, a non-woven fabric and a non-woven fabric, or a loop pile fabric and a non-woven fabric, and these fabrics can be joined easily. There is to get to.

  The first feature of the wire fastener according to the present invention is that the male hook 12 protrudes from the shaft yarn 11 to form a linear shape.

  The second feature of the wire fastener according to the present invention is that, in addition to the first feature, the shaft yarn 11 is constituted by a plurality of core yarns, and the male hook 12 is interposed between the plurality of core yarns. The root 14 is intertwined.

  A third feature of the wire fastener according to the present invention is that, in addition to the first feature, the shaft yarn 11 has a woven structure composed of weft and warp, and both ends of the warp or weft are cut. And the cut end constitutes a male hook 12.

  A fourth feature of the wire fastener according to the present invention is that, in addition to the first feature described above, the shaft yarn 11 has a warp knitting structure in which the knitting yarn 15 is configured. Both ends are cut, and the cut end constitutes the male hook 12.

  A fifth feature of the wire fastener according to the present invention is that, in addition to the first feature, the shaft yarn 11 is formed by cutting a nonwoven fabric, and the tip of the fiber that appears at the cutting opening forms the male hook 12. It is in the point.

  A sixth feature of the wire fastener according to the present invention is that, in addition to any of the first, second, third, fourth, and fifth features, the male hook 12 has a high melting point polymer as a core component 31. The core-sheath composite fiber yarn 16 (18) having a low melting point polymer as the sheath component 32 is formed by hot-melt cutting and formed into a mushroom type by the hot-melt mass 19 of the core-sheath composite fiber yarn 16 (18). It is in the point.

  The hook-and-loop fastener according to the present invention has a yarn (13) in which a male hook 12 protrudes from a shaft yarn 11, and the male hook 12 is exposed on the surface.

  Nylon, polyester fiber, polypropylene fiber and other thermoplastic synthetic fibers (hereinafter referred to as synthetic fabrics) heaters, heated knives, scissors, rotary blades, ultrasonic cutters, frictional heat generating high-speed thin plates (high-speed When cutting with a cutting device with heat, such as an operating knife, a high-speed operating saw blade, or a high-speed rotating blade), a molten mass 19 is generated at the end of the cut fiber 18 that appears at the cutting port, and the end of the fiber 18 The melted lump 19 exhibits a fastener function for engaging with the loop pile in the same manner as the mushroom type hook. And since it is very easy to cut a synthetic fiber fabric into a thin line shape while heating, the wire fastener 13 can be obtained simply.

  The molten mass 19 that acts as a mushroom-type hook is not heated at the tip of an upright pile, but cuts the fibers that make up a normal synthetic fabric without piles regardless of the thickness of the fibers that make up the pile. Therefore, it is easy to form the male hook 12 with fine fibers 18 having a diameter of less than 10 dtex, and the piles can be repeatedly bonded to and peeled from the loop pile fabric constituted by the fibers having a diameter of less than 10 dtex. It is possible to obtain a male fastener that does not wear due to fuzzy surfaces.

  The wire fastener 13 is a kind of yarn that can be manufactured by cutting a synthetic fabric into thin pieces. Since the male hooks 12 protrude radially from the shaft yarn 11, two pieces to be joined together. Can be sandwiched between loop pile fabrics and non-woven fabrics, and the two fabrics can be joined together via line fasteners 13 so as to be sewn by perforated lines, and the wire fasteners 13 can be attached to either one of the fabrics. It can also be used by stitching, and the intervening portion of the line fastener 13 does not swell greatly, thereby preventing the appearance and texture of the fabric to be joined.

  Since the wire fastener 13 is also a kind of yarn, it can be woven or knitted into the woven fabric or knitted fabric together with the general yarn 24 as a woven yarn or knitted yarn, and the woven or knitted fabric or knitted fabric can be woven or knitted. Since the male hook 12 constituting the outer surface of the wire fastener 13 appears, the woven fabric or knitted fabric can be used as the double-sided male fastener 20, and therefore the double-sided male fastener 20 is used as a normal loom. It can be easily obtained using a knitting machine or a knitting machine (FIG. 2).

  The double-sided male fastener 20 thus obtained has its male hook 12 intertwined with the axial thread 11 and is securely locked, and the axial thread 11 protruding from the male hook 12 is Since it can be used as the wire fastener 13, it is not necessary to make the woven density or knitting density of the double-sided male fastener 20 dense in order to securely lock the male hook 12. A porous, soft and flexible double-sided male fastener 20 can be obtained. The porous, soft and flexible double-sided male fastener 20 does not impair the texture, flexibility, stretchability, breathability, etc. of the fabric to be joined thereby.

  Then, using a yarn card device, a dobby device, or other patterning device, or by hand-weaving, the wire fastener 13 is partially woven or knitted into the woven fabric or knitted fabric (20) so as to draw the pattern, and the woven fabric or knitted fabric. It is also possible to form the male fastener 20 on a part of this, and by doing so, it is possible to save the trouble of positioning, stitching, bonding, etc., which has been conventionally performed for attaching the male fastener. Since the male fastener 20 is an integral part of the woven or knitted fabric as part of the warp, weft, or knitting yarn, the appearance and texture of the woven or knitted fabric are not impaired as in the conventional male fastener.

  In the wire fastener 13, the male hooks 12 protrude radially from the shaft yarn 11, and in the double-sided male fastener 20, the male hooks 12 protrude from the front and back. For this reason, the wire fastener 13 and the double-sided male fastener 20 of the present invention are easy to adhere to various articles using an adhesive. At that time, the male hook 12 bites into the coating film of the adhesive and has a cankering effect. Demonstrate and adhere firmly. For this reason, the wire fastener 13 and the double-sided male fastener 20 of the present invention are bonded to various base materials such as leathers, plastic sheets, metal plates, plywood, as well as fabrics such as woven fabrics, knitted fabrics, and nonwoven fabrics. Various types of single-sided male fasteners can be obtained. Thus, the wire fastener 13 and the double-sided male fastener 20 can be bonded to various articles and used as an anti-slip member as described in Patent Document 3.

  The male hook 12 of the wire fastener 13 has a shape like a pile protruding from the axial thread, like the conventional hook of the conventional surface fastener, but the molding in which the pile protrudes from the axial thread. In accordance with the production method of yarn and chenille yarn, if the fabric 21 for producing a wire fastener is a woven fabric, the weft is cut in parallel with the warp with a heater, a heating cutter, an ultrasonic cutter, etc. If 21 is a warp knitted fabric, the wire fastener 13 which cuts the knitting yarn 16 which has connected between the wales 22 and 22 similarly can be manufactured (FIG. 1). In this case, the weft yarn and the knitting yarn 15 that constitute the shaft yarn 11 without being cut are heat-resistant fibers such as wool fiber, cotton, rayon, glass fiber, and aramid fiber, and are cut. A thermoplastic synthetic fiber having a higher melting point than that of the male hook yarn 16 may be used.

  The wire fastener 13 can be manufactured according to the manufacturing method of the molding yarn or chenille yarn, but can also be manufactured by cutting a conventional synthetic fabric into a tape, a band, or a string, and can also be manufactured using wool fiber or cotton. It can also be produced by cutting a fabric in which a non-thermoplastic fiber such as rayon and a thermoplastic synthetic fiber are mixed (hereinafter referred to as a mixed fabric). In this way, the raw fabric 21 for manufacturing the wire fastener 13 is a male hook yarn corresponding to the pile of the molding yarn as a weft, like the raw fabric for manufacturing the molding yarn, It is not always necessary to weave with a knotted woven structure using the axial yarn corresponding to the core yarn as a warp. In the preferred fabric 21 for wire fastener, the axial yarn 11 forms a straight chain stitch row in the wale direction (22), and the adjacent chain stitch row (11, 11) is connected to the male hook yarn 16. In addition, a warp knitted fabric in which the male hook yarn 16 forms a knit loop 23 integrated with the shaft yarn 11 at the connecting portion and is intertwined with the shaft yarn 11 (FIG. 1). ). More preferably, a heat-fusible fiber is used for a part of the shaft yarn, and the male hook yarn 16 is bonded and fixed to the chain stitch row (11) by heat-sealing it. As the heat-fusible fiber, a fiber composed entirely of a heat-fusible polymer (resin) can be used. Preferably, the fiber becomes a heat-fusible polymer and a non-heat-fusible polymer. A composite fiber, particularly a core-sheath composite fiber yarn having a heat-fusible polymer as a sheath component and a non-heat-fusible polymer as a core component is used.

  When the male hook 12 is composed of fine thermoplastic synthetic fibers 18 of 50 dtex or less, the male hook thread 16 is composed of different types of fibers that are not fused together due to the difference in material, or Further, non-thermoplastic fibers such as wool fibers and rayon may be mixed with the male hook yarns 16 so that the hot-melt mass 19 formed at the end of the thermoplastic synthetic fiber 18 in a mushroom shape is fused. The fine male hook 12 can be densely formed.

  When the male hook 12 is a mushroom hook, the male hook yarn 16 and the thermoplastic synthetic fiber 18 have a high melting point (heat melting temperature) polymer as a core component 31 and a low melting point (heat melting temperature). When using a core-sheath composite fiber yarn having a polymer as a sheath component 32, particularly a core-sheath composite monofilament yarn having a fineness of 100 dtex or more, the neck 30 of the male hook 12, that is, a yarn melted and cut. At the base of the hot melt lump 19 formed in a mushroom shape at the tip of the strip 16 (18), the crystalline region as the fiber of the core component 31 is maintained, the neck 30 is cracked, and the hot melt lump 19 falls off. The durability of the fasteners 13 and 20 is improved (FIG. 3). For this core-sheath composite fiber yarn, it is recommended that a heat-fusible polymer is applied to the sheath component 32 in the same manner as the heat-fusible core-sheath composite fiber yarn for axial yarn.

  The male hook 12 of the wire fastener 13 is not limited to a mushroom hook, but can be a J-shaped hook. For this purpose, a wire fastener base fabric is formed by applying a crimp (bending) fixed to the male hook yarn by the knit de knit method, and after the male hook yarn is cut, the crimp is performed. Is reproduced so that the cutting terminal has a J-shaped shape. When the J-shaped male hook is formed, the wire fastener base fabric 21 is cut at room temperature. In addition, a thick monofilament thread is used for the J-shaped male hook thread similar to a conventional male fastener.

  As described above, in the wire fastener, the warp of the woven fabric is used as the shaft yarn 11 and the weft is cut along the warp according to the manufacturing method of the molding yarn or chenille yarn. Alternatively, as shown in FIG. ) Is formed by cutting the insertion yarn (16) connected between the chain stitch rows along the chain stitch row. As a method of manufacturing a thread, a male hook thread (filament bundle) 16 is spirally wound so that a shaft thread (support strand) 11 is overlapped in parallel with an elongated hook-shaped shaft material (mandrel) 25 and bundled together. Patent No. 3468522 is a method in which the male hook yarn 16 and the shaft yarn 11 are bonded by ultrasonic waves, and then the male hook yarn 16 is cut into a pile (12). Is disclosed. In order to make the male hook 12 into a J-shaped hook-shaped hook, in the manufacturing method of the molding thread of this Japanese Patent No. 3468522, a groove 26 continuing in the length direction is provided in the hook-shaped shaft member 25, and the male hook before cutting The thread 16 is pushed into the groove 26 by the pushing member 27, heated and the shape of the male hook thread 16 pushed into the groove 26 is heat set (FIG. 4), and at the same time or thereafter, the groove 26 It is also possible to cut the male hook thread 16 at the center of the recessed portion that has been depressed by being pressed into a J-shaped hook hook (12).
