Description

  The present invention relates to interior materials such as vehicle interior materials and ceiling decorations, wall decorations, etc. composed of outer and lining materials, indoor equipment such as joinery and chairs whose outer surfaces are decorated with decorative materials, clothing composed of outer and lining materials, etc. It is related with the joining structure of textiles, such as clothes and bedding comprised so that it could detachably with two face materials.

Double-sided pressure-sensitive adhesive tapes and hook-and-loop fasteners are widely used as bonding materials for detachably and securely bonding two large-sized surface materials. In the double-sided pressure-sensitive adhesive tape, there is a risk that the adhesive component becomes adhesive residue when it is peeled off and contaminates the substrate surface, and the surface fastener is advantageous in this respect.
The hook-and-loop fastener includes a female hook-and-loop fastener 58 covered with a non-woven fabric or loop pile 54 made of fibers having a single fiber fineness of 30 dtex or less, and a male hook-and-loop fastener 57 from which a hook element protrudes (see FIG. 14). ). A fiber having a single fiber fineness of 70 to 1000 d (denier) is used for the hook element (Patent Document 1).

  The hook element includes a hook-shaped hook having a J-shape resembling a spine of a plant seed such as a male itch, a cow knee, and a thistle, and a mushroom-type hook 55 formed by a fiber terminal expanded like a cocoon. (See FIG. 14). The mushroom-shaped hook is formed by heating and melting the tip of the cut pile protruding from the water surface of the immersed cut pile fabric (Patent Documents 2, 3, and 4). The outer diameter of the mushroom type hook is 2 to 4 times the outer diameter of the fibers of the cut pile 56. For the mushroom-shaped hook, a monofilament that is thick and rigid so that the tip protrudes from the water surface without being pulled down by the surface tension of water when immersed is used for the cut pile 56, and the single fiber fineness is 10 dtex or less. It is difficult to make a mushroom-shaped hook with a soft thin monofilament.

  Regarding mushroom-shaped hooks, it has also been proposed to form a mushroom-shaped hook by applying a direct flame to the surface of a needle punched nonwoven fabric (Patent Document 5). However, in practice, the fiber fluff on the surface of the nival punch nonwoven fabric subjected to direct flame tends to be a molten resin film (Patent Document 6), and it is difficult to form a mushroom-shaped hook as ideal.

  In the conventional male hook-and-loop fastener, the long and rigid cut pile 56 stands up so that it can be taken into the thick female hook-and-loop fastener. In some cases, the hook element is set while being pushed down to change the thickness, so that it is not suitable for a joining jig for interior materials that detachably attach the surface decorative material and the backing material.

Therefore, a surface fastener has been devised that is thin and soft and does not change its thickness even when pressed for a long period of time, and has a wide surface to removably engage the surface decorative material and the backing (Patent Document 7).
The hook-and-loop fastener is composed of (a) a fabric in which a fracture end 11 of a thermoplastic synthetic fiber having a melt 26 which is heated and melted is fixed to the tip, and the male engagement element is on the surface. A male surface fastener constituted by a breaking end of the breaking fiber 33 exposed to the fabric, and (b) a fabric in which surface fibers 34 whose both ends are locked to the fabric body are exposed on the surface, The female engagement element is constituted by a female surface fastener constituted by surface fibers 34 exposed on the surface.

  As the male surface fastener in which the melt 26 is fixed to the breaking end of the breaking fiber 33, the pile yarn loop of the pile yarn is broken during the weaving and weaving process to form the longitudinal fiber of the cut pile fabric. The cut pile surface where the breaking ends of the breaking fiber 33 standing up from the base fabric is exposed is irradiated with a laser beam, and the breaking terminal 11 standing at the irradiated portion is heated and melted to generate a melt 26, That is, in addition to the broken fiber upright male surface fastener where the fiber is broken before heating and melting where the melt 26 is generated, on the surface of the sideways fiber in a state of being laid down in a direction continuing parallel to the surface of the fabric after manufacture. When the laser beam is irradiated, the transverse fiber at the irradiated portion is heated and melted and melted and broken, and a melt 26 is generated and fixed on the broken end 11 of the broken fiber 33. That is, the melt is heated and melted. Breaking fibers sideways type male surface fastener became cross fibers 33 have also been devised.

A general fabric such as a woven fabric, a knitted fabric, or a non-woven fabric in which both ends of the surface fiber 34 exposed on the surface are locked to the fabric body is a ruptured fiber lateral type male mold even for a ruptured fiber standing type male surface fastener. Also for the hook-and-loop fasteners, the surface fibers 34 were caught by the melt 26 fixed to the surfaces of the hook-and-loop fasteners, and the function as a female hook-and-loop fastener was exhibited.
However, the surface fiber 34 does not get caught by the melt 26 in the bulky fabric that the surface fiber 34 swells and looks easy to be caught by the melt 26 of the male hook-and-loop fastener, and functions as a female hook-and-loop fastener. It was found that there were surprisingly many fabrics that did not.

Therefore, earnest research was conducted on the joint relationship between the male surface fastener and the fabric in which the surface fibers bulge on the surface, and the following knowledge was obtained.
(Knowledge 1)
A broken fiber standing male surface fastener and a broken fiber lateral male surface fastener (hereinafter collectively referred to as “broken fiber melted male surface fastener” together) are male engaging elements. Is supported by a broken fiber having a single fiber fineness of 50 dtex or less, and a conventional hook-shaped hook or mushroom-type hook (supported by a thick fiber having a single fiber fineness of 77 dtex (70 denier) or more ( 14), the thickness of the supporting fiber is remarkably different and thin, and the male engagement elements are called “breaking fiber fusion element” in view of these common points. It can be distinguished from the conventional hook and mushroom type hooks.
(Knowledge 2)
Due to the fineness of the single fiber fineness, which is the difference between hook-shaped hooks and mushroom-type hooks, fractured fiber fusion type elements are similar to conventional hook-shaped hooks and mushroom-type hooks against female surface fasteners. It differs from a hook-shaped hook or a mushroom-type hook in that it has a close-contact engagement structure in which it is pressed and tangled in close contact with the fiber of the female surface fastener, instead of the intrusion engagement structure.
(Knowledge 3)
Due to the difference in the engagement structure at the initial stage of engagement, the fractured fiber fusion type element has a hook type locking structure that is hooked on one fiber thread of a conventional hook-type hook or female hook-and-loop type hook hook. Rather, it is also a hook-shaped hook or mushroom in that it has an internal pressure action type locking structure that receives internal pressure from a large number of surrounding fibers and is entangled with and locked to a single fiber surface fastener. It is different from the mold hook.
(Knowledge 4)
The broken fiber melt type male surface fastener is different from these hook-shaped hooks and mushroom-type hooks, particularly in the close engagement structure in the initial stage of engagement and in the internal pressure action type locking structure in the locked state. When the single fiber fineness of the fiber of the female surface fastener is large and the fiber diameter is large, it is difficult for the melt to reach the back side of one fiber of the female surface fastener to be engaged, and the surface of the single fiber Therefore, the melt is easily slipped off, and the locked state with the female surface fastener becomes unstable.
(Knowledge 5)
In the broken fiber melt type male surface fastener, if the single fiber fineness of the fiber of the female surface fastener is thick and the fiber diameter is thick, the gap between the fibers inside the female surface fastener into which the broken fiber is fitted becomes rough. Even if a broken fiber is once fitted between the fiber gaps, it becomes easy to come off immediately, and also in this respect, the locked state with the female surface fastener becomes unstable.
(Knowledge 6)
In the fractured fiber fusion type male surface fastener, if the single fiber fineness of the fractured fiber is small and the fiber diameter is narrowed, it will be pushed back by the fiber of the female surface fastener and bend easily. It is difficult for the broken fiber to be fitted into the gap, the melt is difficult to reach to the back side of one fiber of the female surface fastener to be engaged, and the fiber inside the female surface fastener to which the broken fiber is to be locked The locking state becomes unstable.
(Knowledge 7)
In these respects, if the single fiber fineness of the fiber of the female surface fastener is thin and the fiber diameter is thin, the flexibility also increases, so that the fiber of the female surface fastener facing the fractured fiber fusion type element has a pressure from surrounding fibers. It becomes easy to adhere | attach to a broken fiber fusion type | mold element by receiving.
(Knowledge 8)
In addition, since the single fiber fineness of the fiber of the female surface fastener is thin and the fiber diameter is thin, the flexibility is increased. Therefore, the fractured fiber fusion type element is not pushed back by the fiber of the facing female surface fastener. It becomes easy to fit in the gap.
(Knowledge 9)
Furthermore, since the single fiber fineness of the fiber of the female surface fastener is thin and the fiber diameter is thin, the fractured fiber fusion type element can reach the back side of the fiber of the female surface fastener that faces due to the thin fiber diameter of the female surface fastener. It becomes easy to reach | attain and it becomes easy to engage with the fiber of a female surface fastener.
(Knowledge 10)
If the single fiber fineness of the fiber of the female surface fastener is thin and the fiber diameter is thin, the interfiber gap inside the female surface fastener becomes fine and dense, and it is difficult for the fractured fiber fusion type element to come out from the interfiber gap. Thus, the locked state of the broken fiber melted male surface fastener and the female surface fastener becomes stable.

  That is, when the single fiber fineness of the surface fiber 34 of the female surface fastener facing the broken fiber 33 is thin and the fiber diameter becomes thin and flexible, the pressure from the surrounding surface fiber 34 is applied to the opposed broken fiber 33. The melt 26 of the rupture fibers 33 facing each other is pushed into the bulging gap of the surface fibers 34 bulged to the bulk of the female surface fastener, and easily enters and protrudes from the back side of the surface fibers 34. The melt-type male surface fastener and the female surface fastener are securely engaged.

  Moreover, when the single fiber fineness of the surface fiber 34 of the female surface fastener is small and the fiber diameter is small, the inter-fiber gap 28 inside the female surface fastener becomes fine and dense. The melt 26 of broken fibers once fitted in the inter-fiber gap 28 inside the female surface fastener is caught by the surface fibers 34a, 34b,. It becomes difficult. Moreover, the melt once fitted between the fiber gaps inside the female surface fastener is sandwiched between the front and rear surface fibers 34x and the surface fibers 34y and is difficult to escape from the interfiber gap.

  Thus, the locked state of the male surface fastener and the female surface fastener is stabilized. However, if the single fiber fineness of the surface fiber of the female surface fastener is large and the fiber diameter is large, the gap between the fibers inside the female surface fastener to which the end 11 of the broken fiber is to be fitted becomes rough, and the melt is fitted. Even if it is inserted, it is easy to come out, and the locking state between the male surface fastener and the female surface fastener becomes unstable.

  Further, if the single fiber fineness of the surface fiber 34 of the female surface fastener is large and the fiber diameter is large, the end 11 of the relatively thin broken fiber 33 is pushed against the thick surface fiber 34 of the female surface fastener. Returned, it is easy to bend, it is difficult to fit into the inter-fiber gap 28 inside the female surface fastener, and the melt 26 wraps around to the back side of one thick surface fiber 34 to be engaged with the female surface fastener. It becomes difficult to reach from the surface of the single thick surface fiber 34, and the locked state between the fractured fiber fused male surface fastener and the female surface fastener becomes unstable.

  In the present invention, the fractured fiber fusion type male surface fastener and the female surface fastener become difficult to join as the single fiber fineness of the surface fiber of the female surface fastener becomes thicker. It was completed on the basis of the above knowledge that the fiber changes depending on the difference in fineness between the broken fiber of the element and the surface fiber of the female surface fastener, and the above knowledge was confirmed by the effect of the present invention.

The broken fiber melt type male surface fastener to which the present invention is applied includes a broken fiber standing male surface fastener and a broken fiber lateral male surface fastener as described at the beginning. The broken fiber upright male surface fastener is formed by breaking the pile yarn loop of the pile yarn during the weaving and weaving process, and breaking the broken fiber 33 standing from the base fabric forming the longitudinal fiber of the cut pile fabric A male surface fastener in which a melt 26 of the broken fiber 33 is generated and fixed on the cut pile surface where the terminal is exposed, and the broken terminal 11 of the longitudinal fiber is erected at the position where the melt 26 is generated. It is. That is, in the broken fiber upright male surface fastener, the fiber is broken before heating and melting to generate the melt 26 to form a so-called cut pile piece of longitudinal fiber.
On the other hand, the broken fiber lateral type male surface fastener has a melt 26 generated and fixed to the surface of the lateral fiber that is a non-cut pile piece lying down in a direction continuing parallel to the surface of the fabric after production, This is a male surface fastener in which lateral fibers stand up at the location where the melt 26 is generated. That is, in the broken fiber lateral type male surface fastener, the fiber that is the non-cut pile piece before the melt 26 is generated is a horizontal fiber that is laid down in a direction that continues parallel to the surface of the fabric, and the non-cut pile piece. The horizontal surface fiber that is the cut fiber 33 is a non-cut pile piece, and the melt 26 is generated and broken. It does not stand up from the surface of the fabric like a cut pile piece.

As described above, the fractured fiber fusion type male surface fastener to which the present invention is applied includes longitudinal fibers (cut pile pieces) and transverse fibers (non-cut pile pieces) whose inclination to the fabric is generally different by 90 °. . The longitudinal fibers (cut pile pieces) of the broken fiber standing male surface fastener can be regarded as cut pile pieces, and the melt 26 generated at the ends of the longitudinal fibers is a mushroom type mushroom type surface fastener. Reminiscent of hooks. However, the melt 26 generated at the tip of the longitudinal fiber is fine with a particle size of less than 500 μm, and the longitudinal fiber is thermally contracted during the generation process and tilts in an unspecified direction. Shrink. Therefore, the heat-shrinkable fiber terminal 11 does not protrude at right angles to the fabric like the longitudinal fiber before heat shrinkage, and is inclined in an unspecified direction and distributed on the surface of the broken fiber upright male surface fastener. ing.
On the other hand, even if it can be imagined that the broken side fibers (non-cut pile pieces) of the broken fiber side-facing male surface fastener are lying down in the direction that continues parallel to the surface of the fabric, the breaking process It is heat-shrinked, and it is crimped by tilting in an unspecified direction.
Therefore, the fiber terminal 11 that has been broken by heat shrinkage is not parallel to the surface of the fabric like a sideways fiber, and is inclined in an unspecified direction, like the fiber terminal 11 of the broken fiber upright male surface fastener. And distributed on the surface of the broken fiber lateral type male surface fastener.

  In this way, the end 11 of the broken fiber 33 of the broken fiber standing male surface fastener and the end 11 of the broken fiber 33 of the broken fiber lateral type male surface fastener are both finely crimped and inclined in an unspecified direction. As shown in FIGS. 5, 6, 7, and 8, the ends 11 of the broken fibers 33 appearing on the critical surface of the contact area with the mold surface fastener 24 are both finely crimped and inclined in an unspecified direction. In addition, both have a property of being entangled with the fine surface fibers 34 of the female surface fastener 24. Therefore, in the present invention, the end 11 of the fracture fiber (cut pile piece) of the fractured fiber standing type male surface fastener is equivalent to the end 11 of the fracture fiber (non-cut pile piece) of the lateral fiber type male surface fastener. Are treated as

FIG. 6 shows a male surface fastener 14 using a thermoplastic synthetic fiber having a single fiber fineness of less than 5 dtex as a broken fiber 33 and a female surface using a thermoplastic synthetic fiber having a single fiber fineness of 5 dtex or more as a surface fiber 34. It is a perspective view which expands and shows the critical surface of the contact location of the female surface fastener 24 and the male surface fastener 14 seen from the back side at the time of overlapping the fastener 24.
In the critical plane, as shown in the drawing, when the fineness of the surface fibers 34 of the female surface fastener 24 is increased and the fiber diameter is increased, rough undulations corresponding to the thickness of the surface fibers 34 are formed on the female surface fastener 24. The surface fiber 34 becomes rigid while occurring on the critical surface, and no elastic deformation is observed in the rough undulations generated according to the thickness of the surface fiber 34.

Accordingly, when the superposed female surface fastener 24 shown in FIG. 6 is pressed against the male surface fastener 14 to be brought into close contact therewith, the broken fibers 33h, 33i, 33j and the female surface fastener 24 interposed on the surface of the male surface fastener. The relationship of the surface fibers 34 is as follows.
(1) Even if an attempt is made to push the broken fibers 33h, 33i, 33j intervening on the surface of the male surface fastener into the interfiber gap 28 of the female surface fastener 24, the interfiber gap 28 of the female surface fastener 24 spreads. It is difficult, and the broken fibers 33h, 33i, 33j of the male surface fastener are pushed back by the surface fiber 34 and are not pushed into the inter-fiber gap 28 of the female surface fastener 24.
(2) Even if a part of the broken fibers 33h are fitted into a rough depression on the surface of the female surface fastener 24, the broken fibers 33h are not entangled with the surface fiber 34 if the shape of the depression does not change elastically.
(3) Even if the other part of the broken fiber 33i is pushed into the interfiber gap 28 without being pushed back by the surface fiber 34, the interfiber gap 28 is not spread to the broken fiber 33i, It is merely a rough and deep depression formed according to the thickness of the surface fiber 34, and the broken fiber 33 i is merely loosely fitted and does not become entangled with the surface fiber 34.
(4) Even if another part of the broken fiber 33j is pushed into the inter-fiber gap 28 and goes around the back surface of the front surface fiber 34, it is loosely fitted into the rough and deep recess as with the previous broken fiber 33i. It does not mean that the surface fibers 34 are entangled.

  On the other hand, FIG. 5 shows the male surface fastener 14 using a thermoplastic synthetic fiber having a single fiber fineness of 5 dtex or more as the broken fiber 33 and a thermoplastic synthetic fiber having a single fiber fineness of less than 5 dtex for the surface fiber 34. It is the perspective view which expands and shows the critical surface of the contact location of the female type | mold fastener 24 and the male type | mold fastener 14 seen from the back side of the hook_and_loop | surface fastener of this invention which piled up the female type | mold fastener 24 which carried out. That is, according to the present invention, at the critical surface, as shown in the figure, the fineness of the surface fibers 34 of the female surface fastener 24 is reduced, and when the fiber diameter is reduced, the female surface fastener 24 facing the male surface fastener 14. The critical surface becomes a smooth surface with few undulations and the surface fibers 34 become tough, and the inter-fiber gaps 28 on the surface of the female surface fastener 24 are also easily elastically deformed.

Therefore, when the superposed female surface fastener 24 shown in FIG. 5 is pressed against the male surface fastener 14 to be brought into close contact therewith, the broken fibers 33e, 33f, 33g interposed on the surface of the male surface fastener 14 and the female surface fastener. The relationship between the 24 surface fibers 34 is as follows.
(1) If the broken fibers 33e, 33f, 33g interposed on the surface of the male surface fastener 14 are pushed into the inter-fiber gap 28 of the female surface fastener 24, the surface fiber 34 of the female surface fastener 24 is deformed. As a result, the interfiber gap 28 is expanded, and the broken fibers 33e, 33f, 33g of the male surface fastener 14 are pushed back into the interfiber gap 28 of the female surface fastener 24 without being pushed back by the surface fibers 34.
(2) When a part of the broken fibers 33e is fitted into a fine depression on the surface of the female surface fastener 24, the shape of the depression is elastically changed, and the part of the broken fibers 33e is a surface around the depression. It entangles with the fiber 34.
(3) When the broken fiber 33f is pushed deeply into the inter-fiber gap 28 without being pushed back by the surface fiber 34, the inter-fiber gap 28 is pushed wide by the broken fiber 33f, and the female surface fastener 24 is In the dewetting where the compressive stress that presses against the mold surface fastener 14 does not act, the elastic recovery force that narrows the inter-fiber gap 28 acts on the broken fibers 33 f, so that the broken fibers 33 f are sandwiched between the inter-fiber gaps 28.
(4) When another part of the broken fiber 33g is pushed into the inter-fiber gap 28 and wraps around the back surface of the front surface fiber 34, the elastic recovery force acts to break the broken fiber 33g as in the previous broken fiber 33f. It will be inserted into the inter-fiber gap 28.

Thus, as the fineness is reduced and the fiber diameter is reduced, the flexibility is also increased, and the surface fiber 34 of the female surface fastener 24 is in close contact with the broken fiber 33 of the male surface fastener 14 facing at the critical surface of the contact portion. This becomes easier (see FIGS. 5, 7, and 8).
On the other hand, the melt 26 of the male surface fastener 14 fits into the inter-fiber gap 28 of the female surface fastener 24 without being pushed back by the surface fibers 34 of the female surface fastener 24 facing each other at the critical surface of the contact portion. This becomes easier (see FIGS. 5, 7, and 8).
Then, the melt 26 of the male surface fastener 14 fitted into the interfiber gap 28 of the female surface fastener 24 penetrates the interfiber gap 28 and wraps around to the back side of the surface fiber 34 of the female surface fastener 24. It securely engages with the surface fiber 34 of the mold surface fastener 24 (see FIG. 5).
Further, when the fineness of the surface fiber 34 is small and the fiber diameter is small, the inter-fiber gap 28 inside the female surface fastener 24 is also finely and densely. Therefore, the melt 26 of the male surface fastener 14 is between the fitted fibers. It becomes difficult to escape from the gap 28 (see FIGS. 5, 7, and 8).

  Therefore, according to the present invention, a male hook-and-loop fastener 14 is obtained which has a hook element constituted by broken fibers 33 having a single fiber fineness of 5 dtex or more and 50 dtex or less, is soft to the skin and is gentle to the skin, and engages with the female hook-and-loop fastener 24. I can do it.

The male surface fastener 14 of the present invention is a broken fiber upright male surface fastener in which a melt 26 of the broken end 11 is generated on the cut pile surface of a cut pile fabric in which the broken fiber 33 stands from the base fabric. In addition, even in the case of the broken fiber lateral type male surface fastener in which the melt 26 of the broken end 11 is generated on the surface of the laterally oriented fiber lying in the direction parallel to the surface of the fabric, it is exposed on the surface of the fabric. The thermoplastic synthetic fiber that is formed by generating the melt 26 in the thermoplastic synthetic fiber that is exposed and has a single fiber fineness of 5 dtex or more and 50 dtex or less is in a state of lying down on the surface of the fabric. Alternatively, it may be standing on the surface of the fabric.
Since the male hook-and-loop fastener 14 of the present invention is extremely thin compared to conventional hook-shaped hooks and mushroom-type hooks, it is detachably joined to the female hook-and-loop fastener 24 so as to be detachable (see FIG. 9). Even when it is used for clothing as a lining 31 or an outer fabric 32 (see FIG. 10) or a knot for straight pants 46 or a skirt 47 (see FIG. 11), a pillow cover, a futon cover It is not bulky when used on the lining or outer surface of bedding such as a bedcloth or a bed cover, and does not give an unpleasant feel as if it touched a foreign object.
The base fabric of the male surface fastener 14 of the present invention is a thin fabric with a smooth surface such as a plain woven fabric, a plain knitted fabric or a nonwoven fabric in which the thermoplastic synthetic fiber forming the melt 26 is lying on the surface. Therefore, even when it is used as an interior material, indoor equipment cosmetics, clothes, bedding, etc. by stacking it as a lining or surface, it does not give a bulky impression or a thick and hard impression.
Thus, according to the present invention, it is possible to obtain the hook-and-loop fastener 30 suitable for the use of the interior material, the indoor equipment cosmetics, the clothes, and the bedding.

If the single fiber fineness of the surface fiber 34 of the female surface fastener 24 that engages with the melt 26 that is the male engagement element of the fracture fiber fusion type male surface fastener of the present invention is small and the fiber diameter is small, the flexibility is obtained. The surface fibers 34a facing the melt 26 are easily brought into close contact with the broken fibers 33 under pressure from the surrounding surface fibers (34b, 34c, 34d...) (See FIGS. 7 and 8).
Further, the surface fiber 34 is easily bent when the single fiber fineness is thin and the fiber diameter is thin, and the resistance against the melt 26 that is pushed in is weakened. Therefore, the melt 26 of the male surface fastener 14 faces the female surface facing each other. It is easy to fit into the inter-fiber gap 28 of the female surface fastener 24 without being pushed back by the surface fiber 34a of the fastener (see FIGS. 7 and 8).
Furthermore, when the single fiber fineness of the surface fiber 34 is small and the fiber diameter is thin, the melt 26 of the male surface fastener is easily fitted into the bulging gap of the surface fiber 34 that has bulged to the bulk of the facing female surface fastener. Then, it penetrates the bulging gap 45 and goes around to the back side of the surface fiber 34 so as to be easily protruded, and securely engages with the surface fiber 34 of the female surface fastener.
Further, when the single fiber fineness of the surface fiber 34 is thin and the fiber diameter is thin, the inter-fiber gap 28 inside the female surface fastener becomes fine and dense, and the melt 26 is difficult to escape from the inter-fiber gap 28 that is fitted. The locked state of the male surface fastener and the female surface fastener is stabilized (see FIGS. 7 and 8).
In the present invention, the single fiber fineness of the broken fiber 33 that supports the melt 26 is 5 dtex or more and 50 dtex or less, the single fiber fineness of the surface fiber 34 of the female surface fastener 24 is less than 3 dtex, and the broken fiber 33 and the surface fiber 34 A fineness difference of 2 dtex or more and 47 dtex or less is provided between them. Then, since the single fiber fineness of the cocoon fiber is around 1 dtex, if the cocoon fiber is used for the surface fiber 34, the fineness difference between the broken fiber 33 and the surface fiber 34 becomes 2 dtex or more and 47 dtex or less, and the male surface fastener. 14 and the female surface fastener 24 have a peel resistance of 100 g / m ² or more, and a surface fastener is obtained in which the male surface fastener 14 and the female surface fastener 24 are securely engaged with each other.

Since the surface fibers 34 crimped like crimped fibers are easily entangled, a bulky inter-fiber gap 28 in which the melt 26 can easily be fitted is easily formed on the surface of the female surface fastener 24. In order to make it appear bulky on the surface of the female surface fastener 24 in this way, the exposed length of the surface fiber 34 exposed on the surface of the female surface fastener 24 is 20 times or more the fiber diameter of the surface fiber 34. It is good to. Here, the fiber diameter D (μm) is expressed by a relational expression “D (μm) = 11 when the specific gravity of the surface fiber is ρ and the single fiber fineness of the surface fiber is N (dtex). 28x
(N ÷ ρ) ^1/2 ”.

  The single fiber fineness of the rupture fiber 33 of the male surface fastener 14 is 6 dtex or more and 25 dtex or less, the single fiber fineness of the surface fiber 34 of the female surface fastener 24 is less than 2 dtex, and the rupture fiber 33 and the female mold of the male surface fastener 14 are set. When the difference in single fiber fineness of the surface fibers 34 of the surface fastener 24 is 4 dtex or more and 23 dtex or less, the peel resistance between the male surface fastener and the female surface fastener is further increased. For this purpose, the single fiber fineness of the broken fiber 33 is set to 7 dtex or more and 20 dtex or less, the single fiber fineness of the surface fiber 34 is set to less than 0.5 dtex, more preferably less than 0.05 dtex, and the single fiber fineness of the broken fiber 33 and the surface fiber 34 is determined. It is recommended that the fiber fineness difference be 6 dtex or more and 19 dtex or less. Further, if the generation density of the melt 26 of the male surface fastener becomes dense, the peel strength between the male surface fastener and the female surface fastener becomes stronger, and the male surface fastener and the female surface fastener are used during use. The surface fastener 30 is obtained in which the male surface fastener and the female surface fastener are securely engaged with each other without being lifted off.

  On the surface of the male surface fastener 14, the melt 26 connecting the plurality of broken fibers (33a, 33b, 33c) is supported and locked by the plurality of broken fibers (33a, 33b, 33c) bound together. Therefore, it is difficult to detach from the broken terminal 11, and the surface of the exposed melt 26 is resinized to improve the durability of the male surface fastener 14.

In the male surface fastener 14 having the sixth feature of the present invention, the male engagement elements formed by the melt 26 are scattered and supported by the break terminals 11 of the break fibers 33, so that the weight is light. It is easy to handle, is flexible and stretchable, and is well adapted to the rough construction surface (see Fig. 2).

The male surface fastener 14 having the seventh feature of the present invention is suitable for the surface of the interior material because the decorative material 16 is laminated on the surface of the synthetic resin layer 15.

In the male surface fastener 14 having the eighth feature of the present invention, the male surface fastener base fabric 17 to be the broken fiber 33 is a fragmented piece 18, so that it is easy to handle with extremely light mass and extremely flexible. It is well suited to the rough construction surface and is easy to install, and is suitable for interior materials.

Since the synthetic resin layer 15 is foamed, the male surface fastener 14 having the ninth feature of the present invention has a good cushioning property and is suitable for an interior material suitable for soundproofing and heat insulation construction.

In the male surface fastener 14 having the tenth feature of the present invention, the melt 26 is supported by the broken ends 11 of the broken fibers 33 and is scattered directly on the back surface of the decorative material 16. Light mass and easy handling (see Fig. 3).

Since the male surface fastener 14 having the eleventh feature of the present invention is bonded to the decorative material 16 in the form of a fragment 18 in which the raw fabric 17 of the male surface fastener serving as the breaking fiber 33 is divided, it is extremely thin. Light weight and easy to use for clothes and bedding.

In the male surface fastener 14 having the eighth and eleventh features , the synthetic resin sheet (15) and the decorative material (16) for supporting the raw fabric 17 are used as the base material (15, 16) of the male surface fastener 14. If so, depending on the physical properties of the base material (15, 16), elasticity, elasticity, cushioning, heat insulation, heat insulation, sound absorption, sound insulation, sound insulation, flexibility and rigidity, water resistance, flame resistance, etc. Excellent in various physical properties, and has a fundamentally different structure from the conventional mushroom-type hook 55 (see FIG. 14). A very new male hook-and-loop fastener 14 is obtained as if a piece 18 as a male engaging element protrudes from the base material, such as a rice plant, and the spear 18 is also planted on the base material (15, 16). (See FIGS. 2 and 3).

The raw fabric 17 of the male surface fastener of the present invention, having a basis weight less than 50 g / m ^2, typically 25g preferably a basis weight of less than 40 g / m ^2, more preferably a basis weight in 15 g / m ² or more 35 g / m ² or less / M ² ultra-thin woven fabric or ultra-thin knitted fabric with a fine and uniform gap between fibers and a distribution density of gaps in a rectangular area of 10 mm in length and width of 5 pieces / cm ² or more, for example, tricot nylon half or spider web When using an ultra-thin non-woven fabric that can be seen through the front and back as described above, the fiber yarn constituting the raw fabric 17 is broken and divided into fine fragments 18 when irradiated with a laser beam, and the wrinkles are also synthetic resin sheets (15) and The male surface fastener 14 is obtained as if the pieces 18 with the melt 26 adhered to the decorative material (16) are dispersed and bonded (see FIGS. 2 and 3).

For this purpose, the base cloth 17 may be irradiated with a laser beam after the base cloth 17 is bonded to the synthetic resin sheet (15) or the decorative material (16). For this purpose, relatively thick fibers having a single fiber fineness of 5 dtex or more and 50 dtex or less, preferably 10 dtex or more and 40 dtex or less, more preferably 15 dtex or more and 35 dtex or less and generally 25 dtex are used for the raw fabric 17 (see FIG. 4). ). Then, when the laser beam is irradiated, the whole broken fiber 33 is not melted to form a film, and a fragment 18 covered with the broken fiber 33 protruding from the melt 26 is generated and engaged with the female surface fastener 24. A male engaging element that is easy to do is formed on the surface of the synthetic resin sheet (15) or the decorative material (16) (see FIGS. 2 and 3).

  A polyurethane resin sheet is recommended as the synthetic resin sheet (15). This is because when the gas burner is applied, the surface of the polyurethane resin sheet instantaneously melts and has adhesiveness, and the base fabric 17 can be bonded without using an adhesive.

  In the present invention, a towel fabric in which a loop pile is formed of cocoon fibers is used to measure the peel strength between the male surface fastener and the female surface fastener. The thermoplastic synthetic fiber has various fibers with different specifications such as fiber material, specific gravity, presence / absence of crimp, fiber length, single fiber fineness, etc. Specification of test cloth for measuring peel resistance by thermoplastic synthetic fiber It is because it is difficult to specify. On the other hand, cocoon fiber is a short fiber having natural crimps, a fiber length of 20 to 30 mm, a specific gravity of around 1.50, little variation due to the production area, and a high-quality product of Umishima cocoon single fiber The finest fineness is around 0.69 dtex, but the finest single fiber fineness of Indian cocoons, American cocoons, Egyptian cocoons, etc. has little variation around 1.20 dtex. If cocoon fibers are used, the specifications of the test cloth for measuring peel strength There is a technical merit that it becomes easy to specify. In addition, towel fabrics using cocoon fibers have an economic advantage that they are widely used and can be easily obtained. In addition, the towel fabric using cocoon fibers also has a practical merit that when it is used for the female surface fastener 24, a surface fastener 30 suitable for a hot water mat or a water mat is obtained. Therefore, in the present invention, in order to measure the peel resistance between the male surface fastener and the female surface fastener, a towel fabric in which a loop pile is formed of cocoon fibers is used.

The peel resistance of the male surface fastener 14 using the towel fabric as the female surface fastener 24 is measured by the following procedure (see FIG. 13).
First, the upper plate 51 and the lower plate 52 are supported in parallel and horizontally with the spacer 50 interposed therebetween, and the exposed surface of the melt 26 that is a male engagement element faces downward on the back surface of the upper plate 51. A 10 cm rectangular male surface fastener 14 is attached as a test sample. Next, a rectangular towel fabric of 10 cm in length and width is placed on a flat support plate 53 as a test cloth for the female surface fastener 24 and the loop pile surface is placed upward. Next, the female surface fastener (test cloth) is lifted together with the support plate 53 and brought into close contact with the male surface fastener, and the support plate 53 is pulled down as it is. When the support plate 53 is pulled down, it is observed whether or not the female surface fastener 24 is locked in close contact with the male surface fastener 14 without dropping. When the support plate 53 is pulled down, when the female surface fastener (test cloth) is peeled off from the male surface fastener 14 and dropped, the mass per square meter of the female surface fastener (test cloth) (wg / m ^2). ), The peel resistance strength of the male surface fastener 14 is determined to be equal to or less than the mass (wg / m ² ) per square meter of the female surface fastener (test cloth). When the female surface fastener (test cloth) is in close contact with the male surface fastener 14 without being peeled off, the male surface fastener with the mass (wg / m ² ) per square meter of the female surface fastener (test cloth). The peel strength of 14 is determined to be greater than or equal to the mass (wg / m ² ) per square meter of the female surface fastener (test cloth).

Therefore, in order to determine the peel strength of the male surface fastener 14 of the present invention to be 100 g / m ² or more, a rectangular towel fabric having a vertical and horizontal dimension of 10 cm and a mass of 1 g / sheet is used as the female surface fastener 24. It should be used as a test piece.

  In order to measure the peel strength of the male surface fastener 14, it is advisable to prepare, as a test cloth, towel fabrics cut into a plurality of types of 10 cm rectangles each having different masses per square meter. The plurality of types of test cloths may be ones that are bonded to one side of a certain towel fabric using a lining as a weight to adjust the mass.

The surface fastener 30 having a peel strength of about 100 g / m ² is easily separated into the male surface fastener 14 and the female surface fastener 24. However, in the hook-and-loop fastener 30 that is used in a contaminated part such as a table cloth 40, a place mat 41, a coaster 42, a pot stand 43, and other table rugs (see FIG. 12), the male hook-and-loop fastener on the front side is used. 14 or female surface fasteners 24 should be frequently replaced, washed and reused. At that time, if the peel resistance is strong, it will take time to replace and remove, so it is used for such easily contaminated parts. On the contrary, it is convenient to set the peel strength of the hook-and-loop fastener 30 to about 100 g / m ² .
Therefore, in the present invention, the standard peel strength of the hook-and-loop fastener 30 is defined as 100 g / m ² or more, and the towel cloth made of straw fiber is effective for wiping off moisture and dust, and the table cloth 40, the place mat 41, the coaster. 42, a towel cloth made of silk fiber is defined as a test cloth to replace the female hook-and-loop fastener 24 because it is suitable for a table rug such as 42 and a pot stand 43.

  The smaller the single fiber fineness of the surface fiber 34 of the female surface fastener 24 and the smaller the fiber diameter, the easier the rupture terminal 31 of the broken fiber 33 gets entangled with the surface fiber 34 and the peel resistance of the male surface fastener 14 increases. Become stronger. Therefore, it is recommended to use a split type composite fiber for the surface fiber 34 that can split the single fiber fineness to less than 0.5 dtex, preferably less than 0.05 dtex. When ultrafine fibers are used for the surface fibers 34 of the female surface fastener 24 in this manner, the irradiation density of the laser beam on the raw fabric of the male surface fastener 14 is made dense, and the generation density of the melt 26 is made fine, without making the male fiber fastener 14 dense. The peel strength of the mold surface fastener 14 can be increased, and the male surface fastener 14 having a good touch can be obtained.

  However, this does not mean prohibiting the use of fibers having a single fiber fineness of 3 dtex or more for the surface fibers 34 of the female surface fastener 24. That is, the surface fiber 34 of the female surface fastener 24 is a thick fiber having a single fiber fineness of 5 dtex or more, which is thicker than the fracture fiber of the male surface fastener, and a fine fiber or ultrafine fiber 34 having a single fiber fineness of less than 3 dtex. Can be used together.

This is because even if several kinds of fibers having different single fiber fineness, such as a surface fiber having a single fiber fineness of less than 3 dtex and a surface fiber having a single fiber fineness of 5 dtex or more, are mixed in the female surface fastener 24, all the fibers of the female surface fastener 24 are used. Is not a thick fiber of 5 dtex or more, and the female surface fastener function for the male surface fastener 14 of the surface fiber 34 of less than 3 dtex mixed in the female surface fastener 24 by the mixed thick fiber of 5 dtex or more is This is because it is not damaged. In other words, not all the fibers present on the surface of the male hook-and-loop fastener function as male engagement elements for the fibers of the female hook-and-loop fastener, and all the fibers of the female hook-and-loop fastener are male. It functions as a female engaging element for the surface fastener fibers, and only the surface fibers 34 of less than 3 dtex that touch the melt 26 among the female surface fasteners function as the female surface fastener. It is.
Therefore, even if thick fibers of 8 dtex or more exceeding 3 dtex are mixed on the surface of the female surface fastener 24, or ultrafine fibers of less than 3 dtex are mixed on the surface of the male surface fastener 14, The anti-peeling strength acting between the male surface fastener 14 and the female surface fastener 24 due to the mixed thick fibers and ultrafine fibers is not particularly affected.

  On the other hand, if thick fibers of 3 dtex or more are mixed, the mixed thick fibers can improve physical properties such as wear resistance, tensile strength, tear strength, and shape and dimension stability of the female surface fastener 24. The Similarly, if fine fibers less than 3 dtex and ultrafine fibers less than 0.5 dtex are mixed, the appearance of the male surface fastener 14 is improved by the mixed fine fibers and ultrafine fibers.

  Therefore, a thick type fiber having a single fiber fineness of 5 dtex or more, further 7 dtex or more, which is thicker than the broken fiber of the male surface fastener, together with a fine fiber or ultrafine fiber 34 having a single fiber fineness of less than 3 dtex and a female type surface fastener 24. It is allowed to be mixed with other surface fibers.

  Similarly, a fine fiber having a single fiber fineness of less than 3 dtex or an ultrafine fiber having a single fiber fineness of less than 0.5 dtex, which is finer than the surface fiber of the female surface fastener 24, together with a thick fiber having a single fiber fineness of 5 dtex or more and 50 dtex or less. Mixing with the fastener 14 is also permitted.

  Therefore, a thick type fiber having a single fiber fineness of 5 dtex or more, further 7 dtex or more, which is thicker than the broken fiber of the male type surface fastener, together with a fine fiber or ultrafine fiber 34 having a single fiber fineness of less than 3 dtex, and the female type surface fastener 24. It is allowed to be mixed with other surface fibers. Similarly, the fine surface fibers of the female surface fastener 24 having a fine single fiber fineness of less than 3 dtex or ultrafine fibers of less than 0.5 dtex are used together with thick fibers having a single fiber fineness of 5 dtex or more and 50 dtex or less of the male surface fastener. It is allowed to be mixed with broken fibers. This is because the surface of the male hook-and-loop fastener is not irradiated with a laser beam, and there are broken fibers 33 to which the melt 26 is not fixed, and transverse fibers to which the melt 26 is not fixed. is there. Even if the surface fiber 34 of the female surface fastener is an extra fine fiber of less than 3 dtex with respect to the fiber to which the melt 26 is not fixed, it does not function effectively as a female engagement element.

  As such, not all the surface fibers of the female surface fastener function as all female fibers of the male surface fastener as female engaging elements, and all of the fibers present on the surface of the male surface fastener Since it does not function as a male engagement element for all the surface fibers 34 of the female surface fastener, even if fine fibers less than 3 dtex including ultrafine fibers are mixed on the surface of the male surface fastener, The part of the fine fibers that intervene does not affect the peel resistance that acts freely between the male surface fastener and the female surface fastener.

Therefore, the surface of the female surface fastener 24 together with the fine fibers and the ultrafine fibers 34 having a single fiber fineness of less than 3 dtex, with thick fibers having a broken fiber single fiber fineness of 5 dtex or more, further 7 dtex or more of the male surface fastener. It is allowed to be mixed with fibers.
Similarly, a fine fiber having a single fiber fineness of less than 3 dtex or an ultrafine fiber having a single fiber fineness of less than 0.5 dtex, which is finer than the surface fiber of the female surface fastener, together with a thick broken fiber 33 having a single fiber fineness of 5 dtex or more and 50 dtex or less. It is allowed to be mixed with the mold surface fastener.

  When using female surface fastener 24 with fine surface fibers of less than 3 dtex and thick surface fibers of 3 dtex or more, they are partially used separately, such as checkered pattern, marbling pattern, striped pattern, leopard pattern, lattice pattern, etc. It is good to make it appear on the surface of the female surface fastener 24 in the shape of

  In that case, the portion where the thick fiber appears is made dense and ground thickness, the portion where the fine fiber appears is made rough and bulky, and the compression stress is concentrated on the dense and ground portion where the thick fiber appears, A strong compressive stress is prevented from acting on the rough and bulky portion where the fine fiber appears and is buffered by the portion where the thick fiber appears, and the male surface fastener 14 and the female surface fastener 24 The peel strength acting between the two is maintained.

  The same applies to the case where thick fibers having a single fiber fineness of 5 dtex or more of the male surface fastener 14 and fine fibers having a single fiber fineness of less than 5 dtex are mixed, and the thick fibers and fine fibers to be mixed are used. Are used on the surface in a pattern such as checkered pattern, marbling pattern, striped pattern, leopard pattern, and lattice pattern.

  The same applies to the case where a thin fiber having a single fiber fineness of less than 3 dtex and a thick fiber having a single fiber fineness of 5 dtex or more are mixed in the female surface fastener 24, and the single fiber fineness of the fine fiber is less than 2 dtex. And preferably less than 0.5 dtex, more preferably less than 0.05 dtex. In particular, in the case of female surface fasteners that do not require laser beam irradiation, the woven or knitted structure is changed to use fine fibers and thick fibers separately. Weaving and knitting to the ground thickness with a dense woven and knitted structure density compared to the knitted part. Also, making the total fineness and thickness of the woven and knitted yarns composed of thick fibers thicker than the total fineness and thickness of the woven and knitted yarns composed of fine fibers is the part of the fine fibers woven and knitted. In comparison with this, it is preferable to thicken the portion where the thick fiber is woven and knitted.

  The melt 26 of the male surface fastener 14 can be generated in the broken fiber 33 by being irradiated with a laser beam, heated and melted. Whether or not the melt 26 is generated by being heated by a laser beam can be easily determined by the size and shape of the melt 26. That is, the melt 26 generated by heating with a laser beam is fine enough to be pushed into the bulging gaps of the surface fibers 34 bulged to the bulk of the female surface fastener, and the particle size is generally 500 μm or less. The welded product of a plurality of matching broken fibers (33a, 33b, 33c) has a undulating complex granular shape (see FIGS. 7 and 8). In that respect, the melt 26 generated by being heated by the laser beam is different in size and shape from the melt formed by continuously spreading the fiber melted by the direct flame into a film shape, and is generated by ultrasonic waves. The film does not become like the melt. Further, when using a flame radiating device, the flame diffuses to a diameter of 5 mm or more, and a wide range having a diameter of 5 mm or more is heated and melted, so that a fine melt with fine irregularities does not occur. When an ultrasonic sewing machine is used, although it is melted in a fine range, the melt is pushed and spread at the bottom of the recess as in the case of pressing embossing, and is not formed into granules. In the case of using a heater (electric heating element), a fine granular melt having a particle size of 500 μm or less is not generated. Therefore, the melt 26 in the present invention can be specified as a melt generated in a broken fiber that has been deformed by being heated by a laser beam.

For the male surface fastener 14 and the female surface fastener 24, any of a non-cut pile fabric such as a woven fabric, a knitted fabric, a nonwoven fabric, and a loop pile fabric and a cut pile fabric can be used.
When a cut pile fabric is used for the male surface fastener 14, the back stitch surface of the cut pile fabric is irradiated with a laser beam, the back stitch pile fiber is used as a lateral fiber, and a melt 26 is generated on the back stitch surface. I can do it. Since the male surface fastener 14 formed in this way is decorated with a cut pile on one side, it is suitable for the outer material 32 of the interior material and the decorative material (see FIGS. 9 and 10). When the non-cut pile fabric is used for a male surface fastener, that is, a broken fiber lateral-type male surface fastener, the non-cut pile fabric may be a suede artificial leather, and the fineness is 15 to 35 dtex and generally around 25 dtex. the basis weight organized nylon filament may be extremely thin fabric, such as a generally 25 g / m ² before and after the tricot nylon half at 15 to 35 g / m ^2. Further, the nonwoven fabric used for breaking the fibers sideways type male surface fastener as a non-cut pile fabric having a basis weight which may perspective front and back in a spider web so that generally 25 g / m ² before and after heat melting at 15 to 35 g / m ² The fiber polymer may be an ultra-thin spunbonded nonwoven fabric that has been pressed from a spinning nozzle and squeezed from a thermoplastic synthetic fiber deposition web that is in a hot-melt state, and may also be bulky deposited through a spinning card machine. It may be a needle-punched non-woven fabric obtained by subjecting a laminated web of thermoplastic synthetic fibers to ultra-thin needle punching, or may be finished in an ultra-thin suede tone. When a cut pile fabric is used for the female surface fastener 24, a back stitch pile fiber is used as the surface fiber 34. Since this female surface fastener 24 is also decorated with a cut pile on one side, it is suitable for the outer material 32 of interior materials and decorative materials (see FIGS. 9 and 10).

  When the loop pile fabric is used for the male surface fastener 14, the loop pile surface can be irradiated with a laser beam to generate a melt 26, and the back stitch surface can be irradiated with a laser beam to melt the melt on the back stitch surface. 26 can also be generated. However, since the loop pile surface is decorated and is suitable for the surface material 32 of the interior material or the decorative material, it is more advantageous to irradiate the back stitch surface with a laser beam to generate the melt 26 on the surface of the back stitch. When the loop pile fabric is used for the female surface fastener 24, the pile fiber on the loop pile surface can be used as the surface fiber 34, and the back stitch pile fiber can also be used as the surface fiber 34. However, in this case as well, it is more beneficial to use the female surface fastener 24 as the interior material or the outer surface 32 of the decorative material with the loop pile surface facing the front side.

  In practice, a preferred fabric among the fabrics used for the male surface fastener 14 and the female surface fastener 24 is a nonwoven fabric. It can be used as a packaging material from tissue cloths, dishwashing cloths, cleaning cloths such as mops, clothing interlinings, linings for clothing and bags, secondary cloths for carpets and other rugs, filters and seat covers. Non-woven fabrics are used in every field, and various non-woven fabrics with different standards are commercially available and can be obtained easily and inexpensively. Unlike woven fabrics and knitted fabrics, as described above, the fibers are randomly complexed in all directions. In a non-woven fabric with a core-sheath composite fiber coated with a hot-melt adhesive polymer or a non-woven fabric provided with an adhesive polymer. Fiber and fiber entanglement points are joined via an adhesive polymer, and the quality is stable in strength. Male surface fasteners of various standards according to demand can be quickly and economically used. Can be provided, therefore, for reasons other embodiments such fields increases utility value widely present invention.

The non-woven fabric used as the male surface fastener 14 and the female surface fastener 24 may be used as a secondary base fabric of a loop pile fabric or a cut pile fabric with the back stitch surface being bonded to the back stitch surface. It can be used by bonding to a knitted fabric.
Then, not only the loop pile fabric and the cut pile fabric but also many other non-woven fabrics, woven fabrics and knitted fabrics can be used as the male surface fastener 14 and the female surface fastener 24.

  In other words, the uneven surface of a fabric with a large step, such as a back-stitched surface of a tufted loop pile fabric or a tufted cut pile fabric with a large uneven surface, is not directly irradiated with a laser beam, but is irradiated with a laser beam and the melt 26 is irradiated. It is said that it is quicker to stick the generated nonwoven fabric together.

  The use of crimped fibers for the broken fiber 33 of the male surface fastener and the surface fiber 34 of the female surface fastener not only can soften the texture and feel of the male surface fastener 14 and the female surface fastener 24, The gap 28 between the breaking fiber 33 and the breaking fiber 33 with which the male surface fastener comes into contact is widened, so that the surface fiber 34 of the female surface fastener can easily enter, and the surface fiber 34 of the female surface fastener bulges like a ring. Thus, the breaking fiber 33 of the male surface fastener can easily enter, and the peel strength acting detachably between the male surface fastener and the female surface fastener can be increased. Therefore, it is recommended to use crimped fibers for male and female surface fasteners. As described above, it is recommended to use a crimped fiber having a natural crimp as a crimped fiber in a female surface fastener that is not irradiated with a laser beam.

The male hook-and-loop fastener 14 and the female hook-and-loop fastener 24 are provided on the backing 31 and the outer cover 32 in the vehicle door interior material 10, and on the backing, the backrest, and the seating surface in the interior device interior material such as a chair or a chair. In the floor underlay of the vehicle floor interior material, the floor underlay and the foot mat are used separately. In the interior of the ceiling, the wall surface, and the fitting, the floor underlay is used for the construction base material and the decorative material such as the ceiling stretched wall, the wall stretched surface, and the cover surface.
In that case, if the male hook-and-loop fastener 14 is used for the lining 31 of the interior material 10 and a normal fabric such as a woven fabric, a knitted fabric, a non-woven fabric, a loop pile fabric, a cut pile fabric is used for the outer fabric 32, the sound absorbing property and the heat insulating property are obtained. It is practical because interior work with excellent functionality such as heat retention can be performed.

When the male surface fastener 14 and the female surface fastener 24 of the present invention are used for the interior material 10 of the vehicle door, the instrument panel 37 is provided with a decorative frame 38 for fitting the internal material 10, and the decorative frame 38 is provided with the decorative frame 38. The lining 31 and the outer material 32 are inserted in order (see FIG. 9).
In that case, when the male surface fastener 14 is used for the lining 31 that is the base of the interior material 10, a normal fabric such as a woven fabric, a knitted fabric, a non-woven fabric, a loop pile fabric, and a cut pile fabric can be used for the outer fabric 32. So convenient.

When the male hook-and-loop fastener 14 and the female hook-and-loop fastener 24 are used for a chair or a seat chair, the female hook-and-loop fastener is fixed to the base material 13 of the chair or the chair as a lining 31, and the lining 31 is placed on the lining 31. The exposed surfaces of the breaking terminals 11 of the broken fibers are overlapped, and the male surface fastener 14 is detachably joined as a backrest surface 32a or a seat surface 32b.
Then, since the male engagement element does not appear on the backrest or the seat surface in a state where the backrest surface material 32a or the seat surface material 32b is removed, the chair or the seat chair covered with the lining 31 is replaced with a normal chair or It can be used in the same way as a seat chair (see FIG. 10).

  The hook-and-loop fastener according to the present invention uses the male hook-and-loop fastener 14 and the female hook-and-loop fastener 24 for one or both of the knot of the straight pants 46 and the knot of the skirt 47, and the skirt 47 can be freely attached to and detached from the straight pants 46. Can be used for clothes and bedding (see FIG. 11).
