International Publication 2020/153160

However, in the hook-and-loop fastener described in Patent Document 1, the hook-shaped engagement element thread is a very thick fiber of 200 to 400 dtex, so the user can visually recognize the hook-shaped engagement element with the naked eye. When used as clothing, or as a cover material or interior material for automobile car seats, it becomes a constraint on the design, etc., resulting in poor design quality.
Alternatively, as shown in Fig. 17, by simply using a thin male engaging thread and forming a molten mass at the tip of the male engaging thread, a male hook-and-loop fastener can also be used. If the molten lump forms an angle of 90° or more with the length direction, it will not be able to exhibit sufficient peel strength because it will quickly disengage from the female hook-and-loop fastener.

In view of these points, the present invention provides a male hook-and-loop fastener functional fabric that achieves "improved design" and "improved peel strength" by forming a turned part on the tip side of the male pile fibers. An object of the present invention is to provide a method for producing a female hook-and-loop fastener functional fabric, a pair of male and female hook-and-loop fasteners, a male hook-and-loop fastener functional fabric, and a female hook-and-loop fastener functional fabric.

The male hook-and-loop fastener functional fabric 1 according to the present invention is a male hook-and-loop functional fabric having male pile fibers on at least one surface, and the male pile fibers have a single fiber fineness of 0.1 dtex or more. It is a thermoplastic fiber of 15.0 dtex or less, and a turned part is formed on the tip side of the male pile fiber at an angle of less than 90° with the longitudinal direction of the male pile fiber. Features.

A second feature of the male hook-and-loop fastener functional fabric 1 according to the present invention, in addition to the first feature described above, is that the length of the turned portion is 0.1 μm or more and 40.0 μm or less.

A third feature of the male hook-and-loop fastener functional fabric 1 according to the present invention is that, in addition to the first or second feature, the male hook-and-loop functional fabric is a warp pile fabric, and the male pile fibers are is a cut pile, the warp pile density of the male pile fibers is 100,000 fibers/25.4 mm or more and 300,000 fibers/25.4 mm or less, and the pile height of the male pile fibers is 0.1 mm or more and 5. It is at the point where it is 0 mm or less.

Since the turned part 3 on the tip side of the fiber 2 is even smaller, the user cannot see the turned part 3 with the naked eye, and even if it is used for clothing, car seat cover material, interior material, etc., its design etc. It does not become a constraint, and the design quality is improved.
As shown in FIGS. 1 to 4, the length of the male pile fibers can be increased by making the angle between the turned portions 3, which are invisible to the naked eye, and the length direction of the male pile fibers 2 less than 90 degrees. Compared to molten lumps that make an angle of 90° or more with the direction, it is difficult to disengage from the female pile fibers of various female type hook-and-loop fastener functional fabrics, so it is said that it can exhibit stronger peel strength. I can say it.

In addition, by setting the length 3L of the return portion 3 to 0.1 μm or more, it is possible to "improve peel strength" for female pile fibers of various thicknesses in female hook-and-loop fastener functional fabrics. By setting the length 3L of the turned part 3 to 40.0 μm or less, the turned part 3 is too long and bends (bends), or the adjacent male pile fibers 2 are welded together. , it is possible to suppress a decrease in peel strength on the contrary.

Furthermore, the male pile fibers 2 are added to the male hook-and-loop functional fabric 1, which is a warp pile fabric, and the cut pile has a warp pile density of 100,000 pieces/25.4 mm or more and 300,000 pieces/25.4 mm or less, and a pile height of 0.1 mm.

As shown in FIGS. 5 to 7, due to these characteristics, the female pile fiber 12 is made into a very thin fiber with a single fiber fineness of 0.001 dtex or more and 5.000 dtex or less. Even if a person cannot see with the naked eye the area where the male hook-and-loop fastener engages with the functional fabric, and it is used as a material for clothing, a car seat, an interior material, etc., there are restrictions such as its design. The design quality is improved.
As shown in FIGS. 5 to 7, by crimping the loop pile of the female pile fibers 12, a plurality of female pile fibers 12 are intertwined with each other to provide a web-like female pile layer 12'. Even if a molten lump with an angle of 90° or more with the longitudinal direction of the male pile fibers is formed on the male hook-and-loop fastener functional fabric, it will not only be at the tip of the loop pile but also at the middle of the loop pile in the longitudinal direction. The intertwined portions of a plurality of female pile fibers 12 also become engagement points (so-called bulky female pile layers 12'), and as the number of engagement points increases, various It can be said that stronger peel strength can be exhibited even for male hook-and-loop fastener functional fabrics.

Furthermore, by setting the crimp rate of the female pile fibers 12 to 10% or more and 100% or less, the number of engagement points at the midpoint in the length direction of the loop pile or at the mutually intertwined portions of the plurality of female pile fibers 12 can be further increased. It can exhibit sufficient peel strength.

Furthermore, the female type hook-and-loop functional fabric 10, which is a warp pile fabric, has a pile density of female pile fibers 12 of 100,000 pieces/(25.4 mm) ² or more and 400,000 pieces/(25.4 mm) ² or less, and the female pile layer 12 By setting the thickness of ' to 0.1 mm or more and 5.0 mm or less, the number of engagement points with the male hook-and-loop fastener functional fabric increases, and further "improvement of peel strength" can be achieved.

A pair of male and female hook-and-loop fasteners 20 according to the present invention includes a male-type hook-and-loop functional fabric having male pile fibers on at least one surface, and a female-type hook-and-loop functional fabric having female pile fibers on at least one surface. A pair of male and female hook-and-loop fasteners comprising a fabric, wherein the male pile fiber is a thermoplastic fiber with a single fiber fineness of 0.1 dtex or more and 15.0 dtex or less, and the male pile fiber has the A turned portion is formed that forms an angle of less than 90° with the longitudinal direction of the male pile fiber, and the female pile fiber is a thermoplastic fiber with a single fiber fineness of 0.001 dtex or more and 5.000 dtex or less, The female pile fiber is a loop pile, has a crimp according to JIS-L-0208:2006 244, and a web-like female pile layer is formed in which a plurality of the female pile fibers are intertwined with each other, The first feature is that the female pile fibers and the male pile fibers are engaged with each other, and the diameter of the female pile fibers is equal to or less than the length of the turned portion of the male pile fibers.

As shown in FIGS. 1 to 12, due to this feature, as described above, by making the male pile fibers 2 and the female pile fibers 12 thin, unlike Patent Document 1, the tips of the thin male pile fibers 2 Furthermore, the smaller return portion 3 and the engagement portion of the male hook-and-loop fastener functional fabric in the female pile fiber 12 cannot be seen with the naked eye by the user, making it difficult for the user to see with the naked eye. Even if it is used as such, it does not limit the design etc., and the design quality is improved.
As shown in FIGS. 1 to 12, by making the angle between the turned portion 3, which is invisible to the naked eye, and the longitudinal direction of the male pile fibers 2 less than 90°, the functionality of the female hook-and-loop fastener is improved. It becomes difficult to disengage from the female pile fibers 2 of the fabric 1, and by crimping the loop pile of the female pile fibers 12, a plurality of female pile fibers 12 are entangled with each other to form a web-like female pile layer 12. ', and unlike Patent Document 1, not only the tip of the loop pile but also the midway in the length direction of the loop pile and the intertwined portions of the plurality of female pile fibers 12 become engagement points. , the number of engagement points is increased, and furthermore, by making the diameter 12φ of the female pile fiber 12 less than the length 3L of the return portion 3 of the male pile fiber 2, the compatibility between the male type and the female type is improved, and It can be said that it can exhibit strong peel strength.

A method for producing a functional male hook-and-loop fastener fabric 1 according to the present invention is a method for producing a functional fabric for a male hook-and-loop fastener having male pile fibers on at least one surface, wherein the male pile fibers are single fibers. A thermoplastic fiber having a fineness of 0.1 dtex or more and 15.0 dtex or less, and forming a turned part on the tip side of the male pile fiber with an angle of less than 90° with the longitudinal direction of the male pile fiber. The first feature is that it includes a forming step.

As shown in FIGS. 1 to 4, 13, and 14, due to this feature, unlike Patent Document 1, by making the male pile fiber 2 a thin fiber with a single fiber fineness of 0.1 dtex or more and 15.0 dtex or less, Since the turned part 3 on the tip side of the thin male pile fiber 2 is even smaller, the user cannot see the turned part 3 with the naked eye, and even when used for clothing, car seat cover material, interior material, etc. This does not limit the design, etc., and improves the design quality.
Then, as shown in FIGS. 1 to 4, 13, and 14, the turned portions 3, which cannot be visually recognized with the naked eye, are formed so that the angle formed with the longitudinal direction of the male pile fibers 2 is less than 90° in the turned forming step S1. By doing so, the engagement with the female pile fibers of various female hook-and-loop fastener functional fabrics becomes more difficult to disengage compared to a molten lump whose angle with the longitudinal direction of the male pile fibers is 90° or more. , can exhibit stronger peel strength.

A method for manufacturing a female hook-and-loop fastener functional fabric 10 according to the present invention is a method for manufacturing a female-type hook-and-loop functional fabric 10 having female pile fibers on at least one surface, wherein the female pile fibers are single fibers. The female pile fiber is a thermoplastic fiber with a fineness of 0.001 dtex or more and 5.000 dtex or less, and the female pile fiber is a loop pile and has a crimp according to JIS-L-0208:2006 244, and the female pile fiber is A web-like female pile layer in which fibers are intertwined with each other is formed, and the female hook-and-loop fastener functional fabric is a warp pile fabric, with one fabric containing soluble fibers and the other fabric not containing soluble fibers. a weaving step of weaving a double woven fabric by connecting the two fabrics with a warp pile yarn, and after the weaving step, dissolving the soluble fibers in one of the two fabrics of the double woven fabric. The first feature is that the method includes a melting step of forming a loop pile, which is the female pile fiber.

As shown in FIGS. 5 to 7, 15, and 16, due to this feature, the female pile fiber 12 is made into a very thin fiber with a single fiber fineness of 0.001 dtex or more and 5.000 dtex or less, which is different from Patent Document 1. In contrast, the user cannot see with the naked eye the area where the male hook-and-loop fastener engages with the functional fabric, and even if it is used as clothing, car seat cover material, interior material, etc., the design etc. It does not become a constraint and the design quality is improved.
As shown in FIGS. 5 to 7, 15, and 16, by crimping the loop pile of the female pile fibers 12, a plurality of female pile fibers 12 are intertwined with each other to form a web-like female pile layer 12'. Even if a molten lump with an angle of 90° or more with the length direction of the male pile fiber is formed on the male hook-and-loop functional fabric, it will not only be possible to melt the tip of the loop pile but also the loop pile. The midway portion in the length direction and the intertwined portions of a plurality of female pile fibers 12 also become engagement points, increasing the number of engagement points, so even for various male hook-and-loop fastener functional fabrics, It can be said that stronger peel strength can be exhibited.
In addition, in the case where the weaving process S11 and the dissolving process S12 are provided, in the weaving process S11, the warp pile yarns that become the female pile fibers 12 are almost erected, but after the dissolving process S12, the female pile fibers are 12 fall down randomly (the pile height of the loop pile is lower than the distance between one fabric 15 and the other fabric 16 in the weaving process S11), so a plurality of female pile fibers 12 fall down against each other. The female pile layer 12' becomes easier to intertwine and has higher bulkiness, and the number of engagement points for the male hook-and-loop fastener functional fabric increases, thereby further "improving peel strength."

According to the method for producing a male hook-and-loop fastener functional fabric, a female hook-and-loop fastener functional fabric, a pair of male and female hook-and-loop fasteners, and a male hook-and-loop functional fabric and a female hook-and-loop fastener functional fabric according to the present invention, By forming a turned part on the tip side of the male pile fibers, it is possible to achieve ``improved design'' and ``improved peel strength.''

<Overall configuration of a pair of male and female hook-and-loop fasteners 20>
1 to 12 show a pair of male and female hook-and-loop fasteners 20 (hereinafter also referred to as "hooley-and-loop fasteners 20") according to the present invention, and this hook-and-loop fastener 20 is made of the above-mentioned male hook-and-loop fastener functional fabric. 1 (male type fabric 1) and the female type hook-and-loop fastener functional fabric 10 (female type fabric 10) described above.
In the hook-and-loop fastener 20, the male pile fibers 2 of the male fabric 1 and the female pile fibers 12 of the female fabric 10 engage with each other.
Note that one female pile fiber 12 may be engaged with one male pile fiber 2 (in particular, the return portion 3), or alternatively, one male pile fiber 2 may be engaged with a plurality of female pile fibers. Female pile fibers 12 may engage with each other, one female pile fiber 12 may engage with a plurality of male pile fibers 2, or a plurality of female pile fibers 12 may engage with a plurality of male pile fibers 2. It doesn't matter if they engage.
Furthermore, all the male pile fibers 2 may be engaged with any female pile fiber 12, or at least some of the male pile fibers 2 may be engaged with any female pile fiber 12. do not have. Similarly, all the female pile fibers 12 may be engaged with any male pile fiber 2, or at least some of the female pile fibers 12 may be engaged with any male pile fiber 2. I do not care.

The value of the diameter 12φ of the female pile fiber 12 is equal to or less than the value of the length 3L of the turned portion 3 of the male pile fiber 12.
The value of the diameter 12φ of the female pile fiber 12 is not particularly limited as long as it is equal to or less than the value of the length 3L of the turned portion 3 (1.0 times or less), but for example, the lower limit may be 0.1 times or more or , 0.2 times or more, 0.3 times or more, 0.4 times or more, etc.

<1> About pressing the male fabric 1 onto the female fabric 10 As shown in FIG. 9, when the male fabric 1 is pressed against the female fabric 10 in the hook-and-loop fastener 20, the male fabric 1 While the male pile fibers 2 of the female fabric 10 can be said to have a pile row shape, the female pile fibers 12 of the female fabric 10 form a web-like female pile layer 12'. 12' (between the female pile fibers 12).
As a result, the male pile fibers 2 fall down approximately along the surface 10a of the female fabric 10 (the surface of the female pile layer 12'). The tip end passes through or inserts the loop of the female pile fiber 12, which is a loop pile.

Here, the female pile fibers 12, which are loop piles, are not only exposed at the tip end side of the loops on the surface of the female pile layer 12', but also at the middle part of the loops, so that the male pile fibers are exposed. It can be said that the return portion 3 of No. 2 can engage not only the loop tip side of the female pile fiber 12, which is a loop pile, but also the crimped portion in the middle of the loop.
Note that both the male fabric 1 and the female fabric 10 are warp pile fabrics, and when the male fabric 1 is pressed against the female fabric 10, the male pile fibers 2 move in the warp direction (so-called pile row direction). If the female pile fibers 12, which are loop piles, are also woven in the warp direction, the warp direction of the male fabric 1 and the warp direction of the female fabric 10 should be oriented to be approximately orthogonal to each other in plan view. It can be said that by pressing against the loop of the female pile fiber 12, the tip end side of the male pile fiber 2 including the return portion 3 can be easily inserted from the weft direction of the female fabric 10, but on the other hand, the female pile layer Since 12' is web-like, the loops of the female pile fibers 12 are oriented in various directions (see FIG. 7, etc.), so the longitudinal direction of the male fabric 1 and the longitudinal direction of the female fabric 10 can be seen in plan It can also be said that it may be pressed in a substantially parallel direction.

<2> Regarding peeling of the male fabric 1 and the female fabric 10 As shown in FIGS. 10 to 12, when the male fabric 1 and the female fabric 10 are separated (immediately before separation), the male pile fibers 2 Since the female pile fibers 12 are engaged with the return portion 3 of the male fabric 1, the male pile angle of each male pile fiber 2 (bundle of male pile fibers 2) increases (gradually stands up).

It can also be said that it is difficult to damage wood etc. by getting caught on it.
The method for producing the male hook-and-loop fastener functional fabric 1 and the female hook-and-loop fastener functional fabric 10 described above will be explained in detail below.

<Method for manufacturing male hook-and-loop fastener functional fabric 1>
As shown in FIGS. 13 and 14, the above-described method for manufacturing the male hook-and-loop fastener functional fabric 1 (hereinafter also referred to as "method for manufacturing the male fabric 1") includes at least a barb forming step S1 to be described later. There is.
The method for manufacturing the male fabric 1 may include a fabric forming step S0-1, a cutting step S0-2, a heat setting (male heat setting) step S0-3, and a shirring step S0-4, which will be described later.
The method for manufacturing the male fabric 1 may include other steps (for example, a backing step, etc.).

In addition, in the manufacturing method of the male fabric 1, when it has only the turn formation process S1, it is called 1st Embodiment, and when it has fabric formation process S0-1 and turn formation process S1, it is called 2nd Embodiment. In the case where the fabric forming process S0-1, the cutting process S0-2, and the turning forming process S1 are provided, it is considered as a third embodiment, and the fabric forming process S0-1, the cutting process S0-2, and the heat setting process S0-3 are included. The fourth embodiment includes a fabric forming step S0-1, a cutting step S0-2, a heat setting step S0-3, a shirring step S0-4, and a turning step S1. If the device includes a backing process, it will be considered as the fifth embodiment, and if it also includes a backing process, it will be considered as another embodiment.

<Reverse forming step S1>
As shown in FIGS. 13 and 14, in the turning forming step S1, turning portions 3 forming an angle of less than 90° with the longitudinal direction of the male pile fibers 2 are formed on the tip side of the male pile fibers 2 described above. This is the process of
Note that the specific means for forming the barb portion 3 in this barb formation step S1 is not particularly limited.
As a means for forming the turned portions 3, for example, the male pile fibers 2 of the raised fabric (raised fabric in which the turned portions 3 are not formed on the male pile fibers 2 erected from the male base fabric 6) are placed on the heat roller H. The turned portion 3 may be formed by bringing the tip ends of the male pile fibers 2 into contact with each other, or by melting the tip ends of the male pile fibers 2 of the napped fabric R by irradiation with a laser (laser beam).

When forming the return portion 3 by bringing the tip side of the male pile fiber 2 into contact with the heat roller H, the heat roller H itself may be provided with a mechanism that generates heat, or other materials such as metal or the like may be provided in the heating device. The tip side of the male pile fiber 2 may be brought into contact with the roller.
The male pile fibers 2 are brought into contact with the heat roller H between the rotatably arranged heat roller H and a rotatably arranged support roller (such as a rubber roller) G, with the male pile fiber 2 side facing the heat roller H side. When the elongated napped fabric R is passed through, the distance D between the rollers may be smaller than the thickness T of the napped fabric R, and this return forming step S1 is performed with a calendar processing machine. It's okay.
In this case, the temperature of the heat roller H, the passing speed of the elongated napped fabric R, the distance D between the rollers, the thickness of the napped fabric R (thickness when passing between the rollers) T, The rotational speed of the heat roller H, etc. may be set to a predetermined value.
The temperature of the heat roller H is not particularly limited, but may be changed depending on the material of the raised fabric (especially the male pile fibers 2) R, and if the material of the male pile fibers 2 is polyester fiber, For example, the temperature may be 190°C or more and 230°C or less, preferably 195°C or more and 225°C or less, and more preferably 200°C or more and 220°C or less.
The passing speed of the raised fabric R is also not particularly limited, but is, for example, 1 m/min or more and 10 m/min or less, preferably 2 m/min or more and 8 m/min or less, and more preferably 3 m/min or more and 6 m/min or less. Also good.
The distance D between the rollers is also not particularly limited, but may be, for example, 0.1 mm or more and 3.0 mm or less, preferably 0.2 mm or more and 3.0 mm or less, and more preferably 0.3 mm or more and 2.5 mm or less. good.
The thickness T of the raised fabric R is also not particularly limited, but is, for example, 0.1 mm or more and 4.0 mm or less, preferably 0.2 mm or more and 3.5 mm or less, and more preferably 0.3 mm or more and 3.0 mm or less. It's okay.
The thickness T of the raised fabric R may be greater than or equal to the distance D between the rollers, and the value (TD) obtained by subtracting the distance D between the rollers from the thickness T of the raised fabric R is not particularly limited. However, for example, it may be 0.0 mm or more and 2.0 mm or less, preferably 0.1 mm or more and 1.5 mm or less, and more preferably 0.2 mm or more and 1.0 mm or less.
In this way, by making the distance D between the rollers slightly narrower than the thickness T of the raised fabric R, the heat roller H is brought into a state where it slightly contacts (so to speak, strokes) the tip side of the male pile fibers 2, and the return If part 3 is formed, it can be said that a part of the tip side of the male pile fiber 2 is melted, but the tip of the male pile fiber 2 is not melted (as a state between the glass transition point and the melting point). It can also be said that only a part of the side is deformed.

When forming the return portion 3 by laser irradiation, the energy density given to the raised fabric R (energy per unit area on the fabric), laser output (wattage), beam spot moving speed, beam spot diameter, etc. Alternatively, the oscillation frequency, focal length, etc. may be set to predetermined values.
In this case, without adjusting the laser output of the laser beam, etc., the laser beam may be irradiated after applying a melt preservative (such as water) to the raised fabric R that prevents the melting of the thermoplastic male pile fibers 2. .

<Fabric composition process S0-1>
As shown in FIG. 13, in the fabric forming step S0-1, before the above-mentioned turning formation step S1, turning portions 3 are formed on the above-mentioned raised fabric (male pile fibers 2 erected from the male base fabric 6). This is the step of forming R (undrafted fabric).
As mentioned above, when the raised fabric (male fabric 1) R is a warp pile fabric (a double warp pile fabric in which one fabric and the other fabric are connected by a connecting yarn (warp pile yarn)) It can be said that the fabric construction step S0-1 is the textile weaving step S0-1, and the male fabric 1 is a double raschel knitted fabric (a double raschel knitted fabric in which one fabric and the other fabric are connected by a connecting thread). When the connecting yarn is center-cut, the fabric construction step S0-1 can be said to be a knitting step S0-1.
Here, in the case of the textile weaving step S0-1, the loom used in this step is not particularly limited, but may be, for example, a vertical pile loom, a wire moquette loom, a needle loom, a jacquard loom, or the like.
Further, in the case of the knitting process S0-1, the knitting machine used in this process is not particularly limited, but may be, for example, a warp knitting machine such as a double Raschel knitting machine.

<Cut process S0-2>
As shown in FIG. 13, the cutting step S0-2 is a connecting yarn (warp pile yarn) in the warp pile fabric that can become the male pile fiber 2 in the raised fabric R constructed in the fabric construction step S0-1 described above. This is the process of cutting (severing) connecting yarns in double raschel knitted fabrics.
In the cutting step S0-2, when cutting a connecting yarn in a warp pile fabric or a double raschel knitted fabric, the connecting yarn is cut halfway between one fabric and the other fabric (for example, approximately in the middle) using a wire or the like. One of the fabrics constitutes a male base fabric 6, and one of the center-cut connecting yarns constitutes a male pile fiber 2, and the other fabric constitutes another male base fabric 6 and is center-cut. The male pile fiber 2 may be composed of the other connecting yarn.
Note that the cutting of the connecting threads described above and the formation of the fabric described above may be performed in one process, and in this case, the process can also be said to be a fabric construction/cutting process.

<Heat setting (male heat setting) process S0-3>
As shown in FIG. 13, in the male heat setting step S0-3, heat at a predetermined temperature is applied to the raised fabric (so-called gray fabric) R cut in the above-mentioned cutting step S0-2 etc. using a heating device. This is the process of heating (setting with heat).
The male heat setting step S0-3 maintains the form and dimensional stability of the raised fabric R, and also prevents the male pile fibers 2 from slipping out if the wefts of the male base fabric 6 contain fusible yarns. .
Incidentally, the male heat setting step S0-3 can also be called a finishing step or a heat setting step.

<Shirring process S0-4>
As shown in FIG. 13, the shirring process S0-4 is a process in which the male pile fibers 2 of the raised fabric R that have undergone the heat setting process S0-3 etc. are shirred (trimmed, sheared, etc.) using a shearing machine or the like. .
In the shirring step S0-4, by shirring the male pile fibers 2, each male pile fiber 2 is aligned to a predetermined length (pile height), and the thickness T as a raised fabric R is set to a predetermined value. shall be.
As a result, when the tip side of the male pile fiber 2 is brought into contact with the heat roller H in the turning forming step S1, the raised fabric R can be made to have an appropriate thickness T for the distance D between the rollers. I can say that.

<Method for manufacturing female hook-and-loop fastener functional fabric 10>
As shown in FIGS. 15 and 16, one method for manufacturing the above-mentioned female type hook-and-loop fastener functional fabric 10 (hereinafter also referred to as "method for manufacturing female type fabric 10") is such that the female type fabric 10 is In the case of a pile fabric, it may include at least a weaving step S11 and a dissolving step S12, which will be described later.

In the dissolving step S12, if the soluble fibers Y included in one fabric 15 are water-soluble vinylon fibers, water is used to dissolve the soluble fibers Y, and the soluble fibers Y included in one fabric 15 are dissolved using water. When the soluble fiber Y to be used is an acetate fiber, the soluble fiber Y is dissolved using an organic solvent such as 100% acetone or dimethylformamide.
In addition, after the melting process S12, the loop pile that is the female pile fiber 12 falls down randomly due to the distance between the one fabric 15 and the other fabric 16 at the time of the weaving process S11, and the loop pile that is the female pile fiber 12 falls down randomly. The pile height becomes lower, and a plurality of female pile fibers 12 intertwine with each other to form a web-like female pile layer 12'.

In addition, in Comparative Example 2-1, since polyurethane yarns are included in the warp of the fabric serving as the base fabric, the gray fabric separated from the warp pile loom after weaving contracts in the warp direction, causing the female side of the loop pile to shrink. The floating yarn, which is the engaging yarn, floats further upwards, and the female side engaging yarn of the loop pile, which is approximately semi-cylindrical when viewed in the weft direction, is formed. A pile layer on the side is formed.

In Comparative Example 2-2, since the warp of the fabric serving as the base fabric contains polyurethane yarn, although the gray fabric that leaves the warp pile loom shrinks in the warp direction after weaving, the female side engaging yarn The fibers are too thin and stiff, the surface of the male fabric is slimy and has no bulk, and a web-like pile layer on the female side is not formed.

<Peel strength>
The "peel strength" between the male fabric 1 and the female fabric 10 in the hook-and-loop fastener 20 of the present invention was determined using a force gauge (manufactured by Imada Co., Ltd., model number DS2-5N) using a test piece (width 1.5 cm, male and female). (overlapping length of 5.0 cm) or may be measured according to 7.4.2 of JIS-L-3416:2000.
In addition, in the present invention, "according to 7.4.2 of JIS-L-3416:2000" includes being measured as described in 7.4.2 of JIS-L-3416:2000. In addition to this, it also includes being measured by applying the description of the JIS (or by partially changing the tensile speed, etc.).
In this peel strength measurement test, the male fabric 1 and the female fabric 10 are measured using test pieces whose warp direction is the longitudinal direction.
The value of the peel strength between the male fabric 1 and the female fabric 10 is not particularly limited, but it is at least the case that the warp directions of the male fabric 1 and the female fabric 10 are approximately perpendicular to each other and approximately parallel to each other. On the other hand, it may be, for example, 0.8 N (Newton)/cm or more, preferably 1.3 N/cm or more, and more preferably 1.6 N/cm or more.
This peel strength measurement test will be described below.

<Peel strength measurement test>
The peel strength measurement test was carried out using the force gauge described above (or 7.4.2 of JIS-L-3416:2000) using Example 1 of male fabric 1 as the common male side and the female side. When using the female fabric 10 of Example 2 and the female fabrics of Comparative Examples 2-1 and 2-2, the warp direction of the male fabric 1 and the warp direction of the female fabric 10 and the female fabric are The peel strengths obtained in the peel strength measurement test are compared with each other in a substantially parallel state.
The measurement results of this peel strength measurement test are shown in Table 1 below.
In addition, if the peel strength is 0.8 N/cm or more, the peel strength as a hook-and-loop fastener is evaluated as "○", and if the peel strength is less than 0.8 N/cm, it is evaluated as a hook-and-loop fastener. An evaluation of "x" is given if the peel strength is not sufficiently demonstrated.

<Evaluation of peel strength measurement test>
As shown in Table 1, in the female fabric 10 of Example 2, the diameter 12φ of the female pile fibers 12 is equal to or less than the length 3L of the return portion 3 of the male fabric 1, and a plurality of female pile fibers 12 are intertwined with each other to form a web-like female pile layer 12', the peel strength is 1.873 N/cm, which is 0.8 N/cm or more, so the peel strength as a hook-and-loop fastener is It can be said that it is fully demonstrated.
On the other hand, in Comparative Example 2-1, although a web-like pile layer was formed, the bulkiness of the pile layer was inferior to that of Example 2, and the diameter of each fiber of the female side engaging yarn was that of the male fabric. Since it is larger than the length 3L of the return part 3 of No. 1, the peel strength is very weak at 0.265 N/cm, and it is less than 0.8 N/cm, so the peel strength as a hook-and-loop fastener is not fully demonstrated. I can say it.
In addition, in Comparative Example 2-2, although the diameter of each fiber of the female side engaging yarn is shorter than the length 3L of the turned part 3 of the male fabric 1, a web-like pile layer is not formed, so the peel strength is low. is 0.707 N/cm, which is less than 0.8 N/cm, so it can be said that the peel strength as a hook-and-loop fastener is not sufficiently exhibited.
