Description

  The present invention does not require a special manufacturing apparatus, and can be manufactured very easily and inexpensively by using a material that can be easily obtained by using familiar heating means, and is a vehicle interior composed of a front surface and a lining. Interior materials such as wood, ceiling decoration, wall decoration, etc., indoor equipment such as fittings and chairs whose outer surface of the base material is decorated with decorative materials, and two face materials such as clothing made up of outer and lining materials, can be freely engaged and disengaged The present invention relates to a hook-and-loop fastener suitable for a textile product that can be used by joining two face materials such as clothes and bedding.

  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 is composed of a female hook-and-loop fastener functional material 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 functional material 57 from which a hook element protrudes. (See FIG. 21). 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. 21). 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 fiber of the cut pile 56 (see FIG. 21). In the case of a 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 fine 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). In practice, however, the fiber fluff on the surface of the needle punched 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 functional material (see FIG. 21), a long and rigid cut pile 56 stands up so that it can be eaten into the thick female hook-and-loop functional material. When the pressure is applied over a long period of time, the hook element is set while being pushed down and the thickness changes, so it is not suitable for the interior material joining jig that detachably attaches the surface decorative material and the backing material. It is.

  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 broken end of a thermoplastic synthetic fiber having a melt melted by heating is fixed to the tip, and the male engagement element is exposed on the surface. A male surface fastener functional material constituted by the breaking end of the broken fiber, and (b) a fabric in which surface fibers having both ends locked to the fabric body are exposed on the surface, and the female The mold engaging element is composed of a female surface fastener functional material composed of surface fibers exposed on the surface.

  As a male surface fastener functional material whose melt is fixed to the breaking end of the broken fiber, 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 Irradiate the cut pile surface where the break terminal of the broken fiber that stands up from the base fabric that is exposed is exposed to laser light, and heat and melt the break terminal where the irradiation site stands up. In addition to the broken fiber upright male surface fastener functional material where the fiber is broken before heating and melting to generate a melt, on the surface of the sideways fiber in the state of being laid down in a direction parallel to the surface of the fabric after manufacture Irradiated with a laser beam, the transverse fiber at the irradiated part is heated and melted and melted and broken, and a melt is generated and fixed at the broken end of the broken fiber, that is, heated and melted to become a broken fiber. Sectional fibers sideways type male surface fastener functional materials have also been devised.

  As a means for fixing the foot mat laid on the pile surface of the cut pile carpet, it has been attempted to project a large number of protrusions such as hook elements of the male surface fastener functional material on the back surface of the foot mat ( Patent Document 8).

  The bulk density of the pile fiber in the pile layer of the cut pile carpet is less than 10% by volume, and 90% by volume or more of the pile layer is occupied by voids, and the thumbtack inserted into the pile layer is locked to the pile layer. As can be seen from the fact that it can be easily removed without any problems, the projections provided in a large number on the back surface have little effect as means for fixing the slippage of the foot mat on the cut pile surface.

  A general fabric such as a woven fabric, a knitted fabric or a nonwoven fabric in which both ends of the surface fiber exposed on the surface are locked to the fabric body is a ruptured fiber standing type male surface fastener functional material as well as a ruptured fiber lateral type It seems that surface fibers are also caught on the melted material fixed on the surface of the male surface fastener functional material, and the function as the female surface fastener functional material is exhibited. However, in the bulky fabric that the surface fibers bulge and appear to be easily caught by the melt of the male surface fastener functional material, the surface fibers do not get caught by the melt and function as a female surface fastener functional material. There are surprisingly many fabrics that do not exhibit. And the male surface fastener functional material in which the melt is fixed to the break terminal of the broken fiber requires an expensive laser beam irradiation device for forming the melt on the break terminal of the standing cut pile, It is difficult to manufacture simply and inexpensively.

  Accordingly, the present invention does not use a male surface fastener functional material that can be used as a female surface fastener functional material even in a general fabric such as a woven fabric, a knitted fabric, or a nonwoven fabric in which surface fibers are expanded without using an expensive device. It is intended to manufacture easily and inexpensively.

  Another object of the present invention is to provide a male surface fastener functional material that is effective as a slip-fixing fixing means for a foot mat placed on a pile surface of a cut pile carpet.

  In the manufacturing method of the male surface fastener functional material according to the present invention, the surface of the work material 15 whose surface is constituted by the thermoplastic synthetic fiber 25 is applied to the surface of the work material 15 by applying the heating body 16 thereto.

Fused (Fig. 4c), (e The heating body 16 is pulled away from the release sheet 17 (FIG. 4d), (f) The temporarily fused portion is peeled off, and the work material 15 is pulled away from the release sheet 17 (FIG. 4e), (f-1) A non-temporary fusion location other than the fusion location is left as a void 12 (FIG. 4f), (f-2) The film 11 of the hot melt is locally generated on the surface of the work material 15 at the temporary fusion location. At the same time, (f-3) it is characterized in that a tip 18 protruding from the coating 11 toward the void 12 is generated at the periphery of the coating 11 (FIG. 4f).

  The male surface fastener functional material according to the present invention is (1) the surface is composed of a work material 15 composed of thermoplastic synthetic fibers 25, and (2) the surface of the work material 15 is locally localized. (3) The remaining part not covered with the film 11 on the surface of the work material 15 is a void 12 ( 4) The first feature is that the tip 18 having male hook functionality protrudes from the periphery of the coating 11 toward the void 12.

  The second feature of the male surface fastener functional material according to the present invention is that, in addition to the first feature, (5) the surface of the work material 15 is a plurality of thermoplastic composites having a single fiber fineness of less than 100 dtex. It exists in the point comprised by the multifilament yarn comprised by the fiber multifilament 26. FIG.

  The third feature of the male surface fastener functional material according to the present invention is that, in addition to the first feature, (6) the surface of the work material 15 is obtained by dividing the width (w) by the thickness (t). The flattening ratio is 400% or more, that is, the width (w) is four times the thickness (t) or more, and the filament yarn is constituted by a thermoplastic synthetic fiber monofilament 27 having a flat cross section of a single fiber fineness of 100 dtex or more. There is in point.

The ninth feature of the male surface fastener functional material according to the present invention is in addition to any of the first, second, third, fourth, fifth, sixth, seventh and eighth features. The peel strength against the loop pile surface, which is the cocoon fiber of the towel fabric 20 superimposed on the surface, is 100 g / m ² or more.

  A male surface fastener functional material that generates a hot melt of the thermoplastic synthetic fiber 25 on the surface of the work material 15 by applying the heating body 16 to the surface of the work material 15 whose surface is composed of the thermoplastic synthetic fiber. In the manufacturing process, when the heating body 16 is directly pressed against the work material 15 without pressing the release sheet 17 between the work material 15 and the heating body 16, the work material 15 of the temporary heating body 16 is pressed. Even if the contact surface is completely separated, the hot melt of the material 15 to be heated and melted is fluid and sticky and adheres to the heating body 16 and peels off. It cannot be done.

In that respect, similarly, when the releasable sheet 17 is sandwiched, the hot melt having fluidity and adhesiveness cannot adhere to the releasable sheet 17 and peel off.
However, the releasable sheet 17 does not conform to the hot melt of the material 15 to be processed in the heating body (16), and the hot melt does not adhere to the releasable sheet 17 in the heating body (16). When the pressing force acting between the releasable sheet 17 and the work material 15 is weakened, the sheet is instantaneously peeled off.
Even if the hot melt of the work material 15 adheres to the release sheet 17, unlike the heating body 16, the release sheet 17 is not a heating element that generates heat by itself, but instantly when it leaves the heating body 16. And start cooling.
Then, due to the temperature difference and the heat shrinkage difference between the work material 15 that starts cooling at the same time as the releasable sheet 17 and the heat shrinkage rate difference between the hot melt and the releasable sheet 17. Peeling phenomenon occurs due to.

In particular, in the present invention, the male hook functional apex 18 serving as a hook element of the male surface fastener functional material is an eating portion that is temporarily locked to the release sheet 17 and protrudes from the periphery of the coating 11. Since the structure is fine enough to be caught by the surface fibers of the female surface fastener functional material, the heat capacity of the tip 18 is small, and the cooling speed of the tip 18 is fast and starts to cool instantaneously.
Therefore, when the heating body 16 is pulled away from the releasable sheet 17, the workpiece 15 begins to cool immediately and is peeled off from the releasable sheet 17 to constitute a male surface fastener functional material.
Thus, in the film 11 peeled from the releasable sheet 17, innumerable tips 18 are formed like cabbage cut pieces protruding from the periphery, like okonomiyaki turned upside down from an iron plate using cabbage finely chopped as a material. Each of the countless tips 18 functions as a hook element that is hooked on the surface fiber bulging on the surface of the female surface fastener functional material.
Thus, the most characteristic point of the manufacturing method of the present invention is the film / tip maintaining mechanism that is maintained by the release sheet 17 until the shapes of the film 11 and the tip 18 generated by heating are determined.

  Thus, according to the present invention, the surface is composed of the work material 15 composed of thermoplastic synthetic fibers, and a plurality of male hook functional tips 18 composed of thermoplastic synthetic fibers protrude from the periphery. The male surface fastener functional material 14 in which the film 11 is distributed on the surface is obtained (FIGS. 1 to 3).

The most characteristic point of the male surface fastener functional material 14 of the present invention is that one film 11 protruding on the surface does not constitute one hook element, but the peripheral edge of one film 11 protruding on the surface. Each of the numerous tips 18 projecting from the space 12 toward the cavity 12 exhibits a male hook functionality, in other words, a multiple-tip / 1-hook structure.
Accordingly, when the male surface fastener functional material 14 of the present invention is used as a backing material for a foot mat that is used by being placed on the pile surface of a cut pile carpet, a large number of protrusions project from the periphery of the coating 11 toward the void 12. The tip 18 is entangled with the pile fiber of the cut pile layer and functions as a means for preventing the slippage of the foot mat. As described above, according to the present invention, a male surface fastener functional material effective as a slip-fixing fixing means for a foot mat placed on a pile surface of a cut pile carpet can be obtained.

  In the present invention, the “temporary fusion” of the surface of the work material 15 to the releasable sheet 17 means that the pressing force acting between the releasable sheet 17 and the work material 15 is slight. “Adhesion” that peels off instantaneously when weakened, or even if the hot melt of the work material 15 sticks to the release sheet 17, the temperature between the work material 15 and the release sheet 17. It means “adhesion” to the extent that a peeling phenomenon occurs between the hot melt and the releasable sheet 17 due to an interlayer shift due to a difference or a difference in heat shrinkage rate.

The adhesive force between the hot melt and the release sheet 17 is a synthetic fiber hot melt in which the hot melt originally has no adhesive strength or adhesive strength, and the adhesive strength or adhesive strength of the hot melt is weak. It is weak enough to be peeled off instantaneously due to a gap between the hot melt and the release sheet 17 due to a temperature difference between the work material 15 and the release sheet 17 or a difference in thermal shrinkage rate. .
Therefore, the releasable sheet 17 is not required to have a releasability as strong as that found in silicone resin or fluororesin water repellents and oil repellents. Rather, the releasability occurs when heated. It may be as weak as the hot melted material becomes the film 11 and is instantly locked to the release sheet 17.
Therefore, the release sheet 17 includes animal fibers, plant fibers, pulp fibers, cellulose fibers such as rayon and polynosic, non-thermomelt fibers such as glass fibers, and thermoplastic synthetic fibers 25 on the surface of the work material 15. Also, fabrics and papers made of high melting point thermoplastic synthetic fibers having a high melting point are used. Water, soap, surfactant, process oil, machine oil and other oils, and plasticizers can be used as the release agent to be given to improve the release property of the release sheet.
The cheapest release sheet is paper such as newspaper or wrapping paper to which printing ink containing an oil agent or a plasticizer is attached.

As a finishing method of the fabric, there is a method called paper embossing. When the fabric is passed through the embossing roll, the front and back of the fabric are finished smoothly like a paper (paper) having a smooth front and back.
When a release sheet having a smooth surface is applied to the smooth fabric and pressed, the fabric and the release sheet are evenly adhered on the entire surface without unevenness.
However, when a release sheet having a smooth surface is pressed on an ordinary fabric that has not been subjected to paper embossing, the fabric and the release sheet do not adhere evenly on the entire surface and are not evenly adhered to each other. There will be contact spots, which are in close contact with each other and in a peeled state where they are not in close contact with each other.
In the present invention, the term “local”, which means “locally pre-bonding” the surface of the work material 15 to the releasable sheet 17, is generated by overlapping the work material 15 and the releasable sheet 17. The “adhesion portion” distributed in combination with the peeling portion means “temporary fusion” locally, and “temporary fusion at the adhesion portion” distributed in combination with the separation portion.

  Accordingly, when the heating body 16 is heated via the release sheet 17 on which the work material 15 is superimposed, a hot melt is generated at the locally adhered portion, and the release sheet 17 is heated by the heating body 16. When being separated from the surface, the film 11 is locally generated on the surface of the work material 15 as if it was transferred from the releasable sheet 17 to the surface of the work material 15 at the locally adhered portion.

  In the present invention, the tip 18 that functions as a hook element on the peripheral edge of the coating 11 protrudes toward the void 12 that is the peeled portion from the releasable sheet 17, so that the male surface fastener functionality is Material 14 is obtained.

  When a low-melting-point synthetic fiber having a melting point of 150 ° C. or lower, such as polypropylene fiber or polyethylene fiber, is used as the thermoplastic synthetic fiber 25 on the surface of the work material 15, the heating element 16 is separated from the release sheet 17. Since the hot melt instantly peels from the release sheet 17 to form the coating 11 and the tip 18 and is cured, a cooling device that facilitates peeling of the work material 15 and the release sheet 17 is not required. It becomes easy to manufacture the male surface fastener functional material 14 efficiently.

  If the surface is composed of thermoplastic synthetic fibers 25, the back surface is composed of non-thermomelt fibers such as animal fibers, plant fibers, pulp fibers, cellulose fibers such as rayon and polynosic, and glass fibers. Woven fabrics, multiple knitted fabrics, or multilayer laminated nonwoven fabrics can be used as the work material 15. Moreover, if the surface is comprised by the thermoplastic synthetic fiber 25, the non-heat-meltable cloth which contains a non-heat-meltable fiber in the back surface, a non-heat-meltable decorative sheet, a plastic reinforcement material, and a plastic cushion material A material on which a plastic backing such as a hard plate or the like is bonded can also be used for the work material 15.

  In the male surface fastener functional material 14 of the present invention, each of the plurality of tips 18 protruding from the peripheral edge of the single film 11 is caught by the surface fiber bulging on the surface of the female surface fastener functional material. Since the function as a hook element is exhibited, the peel resistance against the female surface fastener functional material is excellent. The contour of the film 11 generated on the surface of the work material 15 varies in size, and the number and contour of the tips 18 generated on the periphery of the coating 11 vary in size. The fineness depends on the size of each of the plurality of tips 18 having different sizes. The surface fibers of the female surface fastener functional material of different sizes are caught. Therefore, according to this invention, the male surface fastener functional material 14 excellent in the versatility with respect to a female surface fastener functional material will be obtained.

  In the work material 15 whose surface is constituted by a multifilament yarn composed of a plurality of thermoplastic synthetic fibers having a single fiber fineness of less than 100 dtex, a male hook functional apex 18 is finely generated at the periphery of the coating 11. Therefore, it becomes easy to be caught by many surface fibers bulging on the surface of the female surface fastener functional material, and the coating 11 is stably supported by the male surface fastener functional material body through a large number of fine thermoplastic synthetic fibers. Thus, the male surface fastener functional material 14 having a good touch and excellent durability can be obtained.

If any of the fabrics, knitted fabrics and non-woven fabrics has not been subjected to paper embossing, as described above, when the smooth release sheet is pressed repeatedly, the fabric and the release sheet are free from unevenness on the entire surface. It is not evenly contacted, there is a contact spot between them, and it is in a peeled state in which it is in close contact with each other and not in close contact with each other. And the male surface fastener functional material 14 in which the voids 12 are mixed are obtained.
However, in the work material 15 having unevenness that is felt as a touch on the surface or visually observed, the film 11 is generated on the top end 34 of the protrusion 33, and the recess becomes a void 12.
Therefore, in the case of using the work material 15 that has regular irregularities that are felt as a touch and visually observed, the male surface fastener functionality in which the coating 11 and the voids 12 are regularly arranged. The material 14 will be obtained.
In the work material 15 having the unevenness formed on the surface as described above, the pressing force is concentrated on the convex portion 33 and the film 11 is easily generated densely, and the male surface fastener functional material 14 is efficiently obtained. It becomes easy.

In the woven fabric, irregularities from which warps and wefts protrude at the knotting points are regularly formed according to the woven structure, and in the knitted fabric, any of the knit loops of the needle loop and sinker loop on the front and back are regularly formed by the knitting yarn according to the knitting structure. It is formed.
When the total fineness of the warp, weft and knitting yarn is 500 dtex or more, the irregularities formed according to the woven structure or the knitting structure can be clearly seen by touch or visual observation.
In this case, warp yarns, weft yarns and knitting yarns are a plurality of thermoplastic synthetic fiber multifilaments 26 having a single fiber fineness of less than 100 dtex, or a thermoplastic synthetic fiber monofilament 27 having a flat cross section having a flatness of 400 dtex or more and a single fiber fineness of 100 dtex or more. , The tip 18 protruding from the peripheral edge of the film 11 becomes hard, and it becomes easy to be caught by the surface fibers bulging on the surface of the female surface fastener functional material, and the peel resistance against the female surface fastener functional material is high. Rise.

FIG. 1 illustrates a coating 11 formed on the top end of a cut pile constituted by a plurality of thermoplastic synthetic fiber multifilaments 26 having a single fiber fineness of less than 100 dtex.
FIG. 2 illustrates a coating 11 formed on the top end of a cut pile made of a thermoplastic synthetic fiber monofilament 27 having a flat cross section with a flatness of 400% or more and a single fiber fineness of 100 dtex or more.

In addition to the woven and knitted structure, the pile fabric is formed by inserting pile yarn into the primary base fabric by tufting, and in the case of non-woven fabric, a fork-type needle is inserted into the fiber web and a part of the fibers is protruded from the surface. You can also.
FIG. 3 illustrates a coating 11 formed on the surface of a nonwoven fabric composed of thermoplastic synthetic fiber monofilaments 27 having a flat cross section with a flatness of 400% or more and a single fiber fineness of 100 dtex or more.

  The unevenness of the surface of the work material 15 depends on the presence or absence of a woven structure, a knitted structure, or a pile, and the work material 15 is subjected to press embossing, or a part of the surface of the work material 15 is removed. Can also be formed.

A flat section monofilament yarn having a flatness ratio of 400% or more and a single fiber fineness of 100 dtex or more expressed by dividing the width (w) by the thickness (t) is a flat cross-sectional shape. Compared to monofilament yarn with a true circular cross section, it is superior in flexibility and flexibility, and is used as a lawn pile for artificial turf for stadium grounds.
When the tip of the turf leaf pile is applied to the heating body 16, the film 11 is melted while being thermally contracted and spreads around the axis Z, and the melt 11 spreads around and the film 11 bordered by the tip 18 is generated. 18 is easily hooked to the surface fibers bulging on the surface of the female surface fastener functional material, and exhibits a hook element function (FIG. 2).
The tip 18 is a kind of molten lump, which has a stable shape and does not deform even when it touches the female surface fastener functional material, and is firmly bonded to a flat filament monofilament body having a single fiber fineness of 100 dtex or more. It is hard to come off.
Therefore, the male surface fastener functional material 14 which is stable in strength can be obtained by adopting a flat section monofilament yarn having a flatness ratio of 400% or more and a single fiber fineness of 100 dtex or more as the work material 15.

The peel strength against the loop pile surface of the woven fiber of the towel fabric 20 superposed on the surface of the male surface fastener functional material 14 according to the present invention is 100 g / m ² or more, whereby the male surface fastener functionality The function as a material is guaranteed.
Anti-peeling strength shown here (100 g / m ² or more), with a material having anti-peeling strength of 100 g / m ² or more to the towel fabric with a loop pile comprising a cotton fiber, the present invention "male surface fastener It is a term that defines the meaning of the term “male hook-and-loop fastener functionality” as “functional material”, and has no more critical significance. Even if it has peel strength, a material having a peel strength of less than 100 g / m ² is excluded from the male surface fastener functional material of the present invention.

Then, the peel resistance strength of the male surface fastener functional material for the towel fabric (test cloth) is measured by the following procedure (see FIG. 20).
First, the upper plate 51 and the lower plate 52 are supported in parallel and horizontally with the spacer 50 interposed therebetween, and the coating 11 made of hot melt in which the tip 18 having male hook functionality protrudes from the back surface of the upper plate 51. A rectangular male surface fastener functional material of 10 cm in length and width is pasted as a test sample with the exposed surface of (melt 26 which is a male engagement element) facing down.
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 a female surface fastener functional material, and the loop pile surface is placed upward.
Next, the female surface fastener functional material (test cloth) is lifted together with the support plate 53 and brought into close contact with the male surface fastener functional material, 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 functional material is locked in close contact with the male surface fastener functional material without falling.
When the support plate 53 is pulled down, if the female surface fastener functional material (test cloth) peels off from the male surface fastener functional material and falls, one square meter of the female surface fastener functional material (test cloth). with a mass (g / m ²⁾ of per determines anti-peeling strength of the male surface fastener functional material mass per square meter of the female surface fastener functional materials (test cloth) (g / m ²⁾ or less and .
When the female surface fastener functional material (test cloth) is in close contact with the male surface fastener functional material without peeling off, the mass per square meter of the female surface fastener functional material (test cloth) (g / m) ² ) The peel resistance strength of the male surface fastener functional material is determined to be not less than the mass (g / m ² ) per square meter of the female surface fastener functional material (test cloth).

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

In order to measure the peel strength of the male surface fastener functional material, 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 with a lining as a weight to adjust the mass.

In the present invention, a towel fabric in which a loop pile is formed of cocoon fibers is used in order to measure the peel strength between the male surface fastener functional material and the female surface fastener functional material.
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.
Moreover, the towel fabric using cocoon fibers also has a practical merit that it is suitable for a hot water mat and a water mat when used as a female surface fastener functional material.
Therefore, in the present invention, in order to measure the peel resistance of the female surface fastener functional material with respect to the female surface fastener functional material, a towel fabric in which a loop pile is formed of cocoon fibers is used.

  The female surface fastener functional material is made of woven fabric, knitted fabric, non-woven fabric, etc., as long as it has surface fibers that are locked to the material body and exposed in parallel to the surface of the material, like a support beam at both ends. Any fabric can be used, and is not limited to the loop pile fabric covered with a loop like the conventional female surface fastener functional material 58.

A preferred fabric as a functional material for female surface fasteners is a relational expression “d (μm) = 11.88 × (n ÷ ε) ^1/2 ” between the specific gravity ε of the surface fiber and the single fiber fineness n (dtex). The calculated outer diameter d (μm) of the surface fiber is 10 minutes of the length protrusion length L (μm) of the tip 18 protruding from the coating 11 on the surface of the male surface fastener functional material toward the cavity 12. 1 or less, in other words, the length L (μm) of the tip 18 is 10 times or more the outer diameter d (μm) of the surface fiber, generally 300 μm or more, preferably female surface fastener functionality In this fabric, the exposed length of the surface fibers exposed on the surface of the fabric 24 is 20 times or more the outer diameter d (μm) of the surface fibers.
Incidentally, since the single fiber fineness of the cocoon fiber is generally around 1.20 dtex and the specific gravity is also around 1.50, the outer diameter d (μm) of the cocoon fiber is generally 15.1 μm (≈11.28 × ( n ÷ ε) ^1/2 On the other hand, the male surface fastener functional material has a tip 18 having a protrusion length L (μm) of generally 151 μm or more.
For this reason, the towel fabric made of cocoon fibers can be suitably used as a female surface fastener functional material.

The multifilament yarn composed of the thermoplastic synthetic fiber multifilament 26 used for the thermoplastic synthetic fiber 25 on the surface of the work material 15 is a long fiber multifilament yarn, a short fiber filament twisted spun yarn, a short fiber filament. Any non-twisted spun yarn may be used.
The filament yarn constituted by the thermoplastic synthetic fiber monofilament 27 having a flat cross section with a single fiber fineness of 100 dtex or more and having a flatness ratio of 400% or more used for the thermoplastic synthetic fiber 25 on the surface of the work material 15 is constituted. The number of monofilaments 27 may be one or more.
The monofilament 27 may be a tape yarn having a plurality of ribs (streaks) 28 extending in the length direction (FIG. 7) or a split yarn having a plurality of slits 29 continuing in the length direction (FIG. 8). Further, it may be folded in the width direction (FIG. 9), or may be a twisted yarn having a twist 30 after being twisted (FIG. 10).

In some cases, only a small household iron 35 is required.
This is the case where a white line is installed on the stadium ground where an artificial lawn is constructed (Fig. 6).
This is because a polypropylene split yarn is used for the lawn leaf pile of the artificial lawn to be processed material 15, and a release sheet 17 prepared by cutting newspaper into a tape shape is provided on the pile surface, If the iron 35 is applied from above, the turf leaf pile 15 is fused to the tape-like release sheet 17, but if the hot melt of the turf pile 15 is cooled, the tape-like release sheet 17 peels off and the film is peeled off. 11 appears, and the tip 18 of the film 11 is bonded to the white-line nonwoven fabric tape (24).

The stadium ground where the artificial lawn is constructed becomes a vast workpiece material 15, but on the contrary, a part of the fine fissures cut at the garment factory is also made the work material 15, and the male part is part of the fissures. Hook functionality can also be added.
As is well known, a tufted pile fabric is produced by inserting pile yarn into a primary base fabric with a needle in a tufted machine and planting the pile. Like the tufted machine, there is a hand-held hook machine called a hand tough machine or a hand tufted machine that uses a single needle to plant the pile on the primary base fabric. This is because, if polypropylene or other thermoplastic synthetic fibers 25 are used for the pile yarn, even a part of the fissure can be used as the work material 15.
The greatest utility of the manufacturing method of the present invention is that the material 15 can be processed in both the fine cut ground and the vast stadium ground, and the male hook functionality can be imparted without using a special manufacturing apparatus. It is in the simplification of the manufacturing apparatus which can obtain the male surface fastener functional material 14 easily and simply.
