Description

  The present invention relates to a pile mat, a cleaning wiping cloth, footwear, or another embodiment of a pile holder in which a pile having self-supporting properties is disposed on a substrate.

  Japanese Patent No. 3177833 (Patent Document 1) describes a foot wipe characterized in that the surface is covered with a pile layer in which a pile having no adhesive resin and a pile in which fibers are set by the adhesive resin are mixed. The invention of the mat is described.

  This foot wiping mat stimulates the soles like a rigid hemp thread to give a refreshing feeling of sarat, and the foot wiping mat does not feel sticky during use, so it does not need to be replaced frequently It is supposed to be.

  In JP-A-2003-111708 (Patent Document 2), at least a main part of the bottom of the sheet-like base is provided with a cut-pile part for wiping and cleaning that has a uniform cut pile, and from the edge of the sheet-like base. A large number of loop piles are disposed over the outside so as to wipe the surface to be cleaned which is wiped at least in the main wiping direction by the cut pile portion, and the cut pile and the loop pile are substantially 0.001 denier or more 0.5. There is described an invention for a cleaning cloth for wiping which is composed of ultrafine fibers of denier or less, and the ultrafine fibers in the cut pile and loop pile are separated from each other at least except the base portions of the cut pile and loop pile.

  Japanese Patent Laid-Open No. 2003-111707 (Patent Document 3) includes a bottom cut pile portion for wiping and cleaning that has cut piles uniformly at least at the main portion of the bottom portion of the sheet-like base portion, and the edge of the sheet-like base portion. Of the parts, at least one of the edges intersecting the main wiping direction of the bottom cut pile part is formed in an edge cut pile part having a cut pile continuously from the bottom cut pile part to the side part, and is in a sheet form A portion of the upper surface portion of the base portion excluding the edge cut pile portion has detachable coupling means for holding the cleaning cloth on the bottom surface side of the cleaning cloth holding body connected to the base portion of the handle of the mop, The cut pile is substantially made of ultrafine fibers having a denier of 0.001 or more and 0.5 denier or less, and the ultrafine fibers in the cut pile exclude at least the base of the cut pile. A cleaning cloth for water wiping having a thick fiber cut pile part formed by a cut pile made up of substantially 1 denier thick fiber partly at the bottom of the sheet-like base part, wherein the parts are separated from each other The invention has been described.

  These dry wiping cleaning cloth and water wiping cleaning cloth are both cut piles made of ultrafine fibers of 0.001 denier or more and 0.5 denier or less on at least the main part of the bottom of the sheet-like base for wiping the object to be cleaned. The ultrafine fibers in these cut piles are such that at least portions other than the base of the cut pile are separated from each other.

However, the piles in the above-mentioned foot wiping mat, the dry wiping cleaning cloth and the water wiping cleaning cloth are all about self-supporting property, elasticity based on the self-supporting property, and improvement and maintenance of absorption and uptake performance of various substances. It was hard to say that it was fully considered.
Japanese Patent No. 3177833 JP 2003-111708 A JP 2003-111707 A

  The present invention has been made in view of the above-described problems existing in the prior art, and its object is to have independence, elasticity based on the independence and absorption of various substances. Another object of the present invention is to provide a pile mat, a cleaning wiping cloth, footwear, or another type of pile holder in which a pile that can improve and maintain the performance of uptake and maintenance is disposed on a substrate.

(1) The pile holder of the present invention that achieves the above object is
A pile holding body comprising a base and a pile, the pile being disposed on the base in a state where the base is bonded to the base,
The outer shape of the pile is a rotating curved surface centered on an axial center line that stands up with respect to the surface of the base body, and at least the end side is reduced to a substantially spherical shape toward the end,
The pile has a large number of fiber filaments densely arranged so as to be substantially radial from at least the base of the axial center line,
The surface portion of the outer shape of the pile, excluding the base side of the base of the pile, is formed by the tip of each linear body,
The pile has a height / base diameter ratio of 1/2 to 3/1 and is self-supporting with respect to the surface of the substrate.

  The outer shape of the pile is a rotating curved surface centered on an axial center line that stands up with respect to the surface of the base body, and at least the end side is reduced in diameter to a substantially spherical shape toward the end portion. A surface portion of the outer shape of the pile, excluding the base side of the pile base, which is composed of a linear body (for example, various synthetic fiber filaments, synthetic fibers, natural fiber staple yarns, etc.) densely arranged so as to be almost radial from the base portion. Is formed by the distal end portion of each of the filaments, and the height / base diameter ratio of the pile is 1/2 to 3/1, which is relatively low compared to the base diameter.

  Therefore, the pile has a self-supporting property and a flexible elasticity with respect to pressing, and is excellent in performance of absorbing and taking in various substances into the pile. That is, the density of the striate body in the pile increases as it goes from the surface portion of the pile toward the inward portion (at least the base portion of the axial center line), and a strong liquid absorption force toward the inward portion of the pile is caused by capillary action. As a result, the pile rapidly moves from the surface where the tip of the striatum is located toward the inward portion to a relatively large amount of liquid (contains no dirt or other substances or contains dirt or other substances. Water or other liquids may simply absorb "water" or "moisture" or "liquid" or "liquid"). In addition, the pile's independence, flexible elasticity, and performance such as absorption and uptake are maintained over a long period of time.

  As the axial center line standing up with respect to the surface of the base body, an axial center line perpendicular to the surface of the base body is most preferable, but for example, about 60 degrees to 90 degrees, or 70 degrees with respect to the surface of the base body, or An axial center line of about 80 to 90 degrees can be mentioned.

  As an example of the outer shape of the pile, the end side has a rotating curved surface shape whose diameter is reduced to a substantially spherical shape toward the end portion, the base side has a substantially cylindrical rotating curved surface shape, and the end portion extends from the base portion to the end portion. And a rotating curved surface whose diameter is reduced to a substantially spherical shape.

  The filaments are densely arranged so as to be almost radial from at least the base of the axial line of the pile. That is, at least the base part of the axial center line of the pile is the center of the radial filament. If only the base part of the axial center line is the center, does the outer shape of the above-mentioned pile form, for example, a rotating curved surface whose diameter from the base part to the end part is reduced to a substantially spherical shape toward the end part? Alternatively, the end portion side has a rotating curved surface shape whose diameter is reduced to a substantially spherical shape toward the end portion, the base side has a substantially cylindrical rotating surface shape, and the substantially cylindrical portion on the base side has an axial dimension. Shorter. When the long part including the base part of the axial center line is the center, the outer shape of the above-described pile is, for example, a rotating curved surface whose diameter is reduced to a substantially spherical shape toward the end part, and the base side is a substantially cylindrical shape. The shape is a rotationally curved surface, and the substantially cylindrical portion on the base side has a longer axial dimension.

  It should be noted that even if some piles that are not necessarily radial are included in the pile, it does not immediately depart from the scope of the present invention.

  (2) In the pile holder of the present invention, it is desirable that the filaments at the base of the pile are parallel to the surface of the substrate.

  In this case, the striate at the base of the pile is parallel to the surface of the base, and thus acts to support the self-supporting of the pile. The pile is more self-supporting and rich in flexible elasticity against pressing. It will be. Parallel to the surface of the substrate includes a linear body slightly downward toward the tip and a linear body slightly upward toward the tip.

  In the pile holders of the present invention, the ratio of the pile height / base diameter is preferably 1/2 to 1 / 0.5.

  When the pile height / base diameter ratio is 1/2 to 1 / 0.5, the pile is more self-supporting. The pile height / base diameter ratio can be 1 / 0.9 to 1 / 0.5, for example.

  (3) Further, in the pile holders of the present invention described above, the pile is formed by twisting a loop portion by a Mole yarn having the filaments as a decoration yarn around the core yarn of the Mole yarn. A core part mainly composed of core yarn is formed at least at the base part of the shaft center line, and at least the end part side has a rotational curved surface part whose diameter is reduced to a substantially spherical shape toward the end part. It can be formed.

  In this case, the pile is formed by twisting the loop portion of the molding yarn around the core yarn of the molding yarn, that is, from one base portion of the loop portion to the end portion of the molding yarn constituting the loop portion. The core part mainly composed of the core yarn is formed at least at the base part of the axial center line of the pile by twisting the constituent part and the part constituting the other base part to the end part around the core thread of both parts. The surface of the rotating curved surface in which a large number of filaments are arranged radially and densely from the core, and the tips of the filaments are reduced in diameter to a substantially spherical shape toward the ends. Forming part.

  (4) In the pile holders of the present invention, it is desirable that the filaments in the pile are non-water-absorbing filaments of 0.05 to 0.8 denier.

  In this case, the outer shape of the pile has a rotating curved surface centered on the axial center line standing with respect to the surface of the base body, and at least the end side is reduced in diameter to a substantially spherical shape toward the end portion. The surface portion of the outer shape excluding the base side of the pile base is made up of 0.05 to 0.8 denier extremely thin non-water-absorbing filaments that are densely arranged so as to be almost radially from at least the base of each filament. It is formed by the front-end | tip part.

  The density of the filament in the pile increases from the surface portion of the pile toward the inward portion (at least the base portion of the axial center line). Therefore, since a strong water absorption force acts toward the inner part of the pile due to capillary action, the pile can quickly absorb water from the surface part where the tip of the filament is located toward at least the base part of the axial center line. Conversely, the tip of the pile that has absorbed water has a low moisture content due to capillary action. The surface portion of the outer shape excluding the base side of the pile base is formed by the tip of the non-water-absorbing filament, so that the area occupied by the fibers is relatively small and the fibers themselves maintain a non-wetting state. . Therefore, the surface portion of the pile in a state where moisture has been absorbed is easily maintained in a relatively dry state, and stickiness is less likely to occur.

  Therefore, this pile can realize high water absorption and high drying property that can absorb water quickly and hardly cause stickiness. In other words, the material that the filament constituting the pile is non-water-absorbing, and the outer shape excluding the base side of the pile base are arranged so that the filament is almost radially formed from at least the base of the axis of the pile. In addition to the structure in which the surface portion is formed by the tip portion of each filament, it is excellent in centrifugal dewaterability or other dewaterability and dryability after dewatering.

  (5) The non-water-absorbing filament may be a polyester, polyamide, polypropylene, or polyethylene filament.

  Further, the non-water-absorbing filament in the pile of the pile-holding body only needs to be non-water-absorbing to such an extent that the above effects can be obtained. For example, the water absorption is 5% or less at 20 ° C. and 65% relative humidity. It can be assumed that

  (6) Each of the pile holders may be for absorbing water by the pile.

  (7) Further, each of the pile holders may be formed by arranging a large number of the piles on a base.

Furthermore, in at least a part of a pile group of piles arranged on the base, the ratio of the distance between the bases of the axial center line / the base diameter of the piles in each pile and two or more other piles adjacent thereto. Can be 1/2 to 3/2.
In this case, the piles are densely arranged in the pile group, and the standing property of the piles is further maintained. In particular, when the ratio of the distance between the bases of the axial center line / the diameter of the base of the pile in each pile and two or more piles adjacent thereto is 1/2 or more and less than 1/1, the piles overlap each other. The pile density is further increased, and the standing property of the pile is further maintained.

  (8) In the pile holders, the base may be a base fabric.

(9) The pile holder of the present invention may constitute a wiping cloth for cleaning such as a mat or a mop wiping cloth. The base fabric may be formed as a bag-like portion into which a user's hand can be inserted, and a wiping tool having a pile on the whole or part of the outer side of the bag-like portion.
Further, for example, the pile holder of the present invention can be used for footwear and other items such as various furniture and slippers.

  The pile holder of the present invention has a self-supporting property, and a pile is provided on the base that can improve and maintain elasticity and absorption and uptake performance of various substances based on the self-supporting property. Yes, it may constitute a pile mat, a wiping cloth for cleaning, footwear or other forms of pile holders.

  Embodiments of the present invention will be described with reference to the drawings.

  (1) FIGS. 1 to 3 all relate to a foot-wiping pile mat as an example of an embodiment of the present invention. FIG. 1 is a schematic front view, and FIG. 2 is a schematic enlarged crossing of a pile. FIG. 3 is a schematic view showing a part of a process of forming a pile with a molding yarn.

  This foot-wiping pile mat A has a pile P whose upper half is substantially hemispherical (substantially hemispherical part Pa) and whose lower half is substantially cylindrical (height / base diameter ratio is substantially 1/1). However, a large number are densely provided on the base fabric S (base), and the base portion of each pile P is coupled to the base fabric S.

Each pile P is formed of a molding yarn M using a non-water-absorbing polyester filament F (striate body) of 0.3 denier as a decorative yarn. That is, as shown in FIG. 3, after the loop portion R is formed on the base fabric S by the stitches of the molding thread M, the end portion from one base portion of the loop portion R to the end of the molding thread M constituting the loop portion R is terminated. The part constituting the part and the part constituting the other base part to the end part are twisted around the core yarn C of both parts. As a result, as shown in FIG. 1, an upright core portion W mainly composed of the core yarn C is formed at least in the lower portion (base portion) of the axial center line of the pile P, and a large number of filaments F are formed from the core portion W. Of the filaments F form a surface portion of a rotationally curved surface in which the upper half of the pile P is reduced to a substantially spherical shape toward the upper end. P is formed.
For example, after forming the loop portion R by the molding yarn M on the base fabric S using the strong twist molding yarn M, each loop portion R is formed of the molding yarn M by performing heat treatment (heat treatment in the dyeing process is preferable). It can be twisted around the core yarn C.

  By providing a large number of rows of seams with such a Mole thread M in parallel, a large number of piles P can be provided on a required surface on the base fabric S. In this way, when a large number of piles P are arranged on a required surface on the base fabric S, stitches (seam intervals) in each stitch row by the Mole yarn M are all the piles, This corresponds to the distance between the bases of the axial centers in the other piles adjacent to the pile. Further, the gauge (interval between adjacent stitch rows) corresponds to the smallest one of the intervals between the bases of the axial centers of the piles on one side and the piles on the other side of the adjacent stitch rows. In the example of FIG. 1, the ratio of the distance between the bases of the shaft center line (stitch) / the diameter of the base of the pile is 5/4. By arranging a large number of seam rows including the stitch position and setting the gauge to 5/4, the distance between the bases of the axis center line / pile of each pile and two or more other piles adjacent to it Pile holders having a base diameter ratio of 5/4 and aligned vertically and horizontally are formed.

  By making the length of the filament F equal to or slightly longer than the base diameter of the pile P so that the height of the core W is about ½ of the height of the pile P A pile P in which the height / base diameter ratio is approximately 1/1 and the outer shape of the upper half is substantially hemispherical (substantially hemispherical portion Pa) and the outer shape of the lower half is substantially cylindrical can be formed.

  The pile P at the right end in FIG. 1 has a ratio of height / base diameter of approximately ½, and the entire outer shape is substantially hemispherical (substantially hemispherical part Pa). In this pile P, the length of the filament F is equal to or slightly longer than the base diameter of the pile P, and the base of the axial center line of the pile P is the core W. Can be formed.

  A large number of piles P arranged on the base fabric S are densely arranged so that an extremely thin non-water-absorbing filament F of 0.3 denier is almost radially formed from the core W at the lower part of the axial center line, The surface portion of the outer shape excluding the base fabric S side of the base portion of the pile P is formed by the tip portion of each filament F.

  In the lower half portion of the substantially cylindrical shape of the pile P, the filaments F are densely arranged in a radial direction about the core portion W that is substantially upright with respect to the base fabric S, and in the axial direction. In the upper half of the substantially hemispherical shape of the pile P, the filaments F are densely arranged so as to be radially radiated about the upper end of the core W. In any part except the base side of the base portion of the pile P, the density of the filament F increases toward the core portion W.

  Therefore, a strong water absorption force acts toward the core portion W below the axial center line of the pile P due to capillary action, so that each pile P is positioned from the surface portion where the tip end portion of the filament F is located. A relatively large amount of water can be quickly absorbed toward the lower part of the axial line.

  On the contrary, the surface part of the upper half part (substantially hemispherical part Pa) that forms a substantially hemispherical shape and the outer peripheral surface part of the lower half part that forms a substantially cylindrical shape in the water-absorbed pile P have a low water content due to capillary action. It becomes. In other words, the surface portion of the upper half portion having a substantially hemispherical shape and the outer peripheral surface portion of the lower half portion having a substantially cylindrical shape are formed by the tip portion of the non-water-absorbing filament F, so the area occupied by the fibers is compared. And the fibers themselves remain non-wetting. Therefore, the surface portion of the pile P that has absorbed moisture is easily maintained in a relatively dry state, and a sticky feeling is less likely to occur.

  Further, the height / base diameter ratio of the pile P is approximately 1/1, and the height is relatively low compared to the base diameter, and the filament F at the base of the pile P is parallel to the surface of the base fabric S. Therefore, it exerts an effect of supporting the independence of the pile P. Therefore, the pile P has high independence with respect to the surface of the base fabric S, and is rich in flexibility with respect to pressing, and the pile P has independence and flexibility, moisture absorption, dryness of the surface portion, and the like. Performance is maintained over a long period of time.

  Therefore, the pile mat A gives a moderate stimulus to the foot that has stepped on the pile P due to the independence of the pile P and the flexible elasticity against the pressure. In addition, this pile mat A can quickly absorb moisture such as a wet foot and the like, and can realize high water absorption and high dryness in which the feeling of stickiness does not occur. An upper half portion (substantially hemispherical portion Pa) having a substantially hemispherical shape and a material that is water-absorbing and its filament F being arranged densely so as to form a substantially radial shape from the core portion W below the axis of the pile P. ) And the structure in which the outer peripheral surface part of the lower half part having a substantially cylindrical shape is formed by the tip part of each filament F, centrifugal dehydration or other dehydration and drying after dehydration Excellent in properties. Moreover, each of these functions is maintained over a long period of time due to the independence of the pile P.

  The filament F can be, for example, 0.05 to 0.8 denier, preferably 0.1 to 0.5 denier, more preferably 0.2 to 0.4 denier. The material of the filament F can be, for example, polyamide, polypropylene, or polyethylene filament F in addition to polyester.

  The core yarn C can be a water absorbent yarn and / or a non-water absorbent yarn. In the case of the molding yarn M in which the filament F as a decorative yarn is fused using a heat-sealing yarn as a part or all of the core yarn C, the filament F can be prevented from falling off with high certainty.

  The base fabric S can be made of water absorbent fibers. Since the base part of each pile P is couple | bonded with the base fabric S, when the base fabric S further absorbs the water | moisture content which the pile P absorbed, many piles P arrange | positioned on the base fabric S can absorb water. It is possible to more effectively prevent the pile P from feeling sticky by increasing the total amount of moisture. In addition, the base fabric S does not necessarily need to consist of a water absorbing fiber.

  As for the shape of the pile, the shape of the surface excluding the base side of the base portion is, for example, a hemispherical shape, a half or less, a half or more spherical shape or an elliptical spherical shape, or a parabolic shape. Can be. These are all substantially spherical. Further, the shape of the pile is such that the surface of the base portion excluding the base side is, for example, hemispherical, 1/2 or less, or 1/2 or more spherical or elliptical spherical, parabolic (That is, a substantially spherical shape), and the base side can be a substantially cylindrical shape or a substantially truncated cone shape.

  The height of the pile can be 3 to 80 mm, for example. The thickness is preferably 5 to 50 mm, more preferably 8 to 40 mm.

  The plurality of piles in the pile mat A or other pile holders may have the same shape and the same size, but may include a plurality of types of piles having different shapes and sizes. By providing the piles closely to the base fabric or other base, for example, the base cloth or the base can be kept invisible between the piles. Yes, but not necessarily.

  As the substrate, in addition to the base fabric (for example, felt, woven fabric, nonwoven fabric, knitted fabric, etc.), for example, a sheet-like material (for example, leather, synthetic resin material, synthetic rubber material, etc.) capable of providing a pile can be used. .

  As the filament, for example, various synthetic fiber filaments, synthetic fibers or natural fiber staple yarns can be used, and the filaments are not necessarily limited to non-water-absorbing filaments.

  When a filament other than a non-water-absorbing filament is used as a filament constituting the pile, the pile has a self-supporting property and has a flexible elasticity against pressing, and absorbs and incorporates various substances into the pile. It is excellent in dripping performance and can absorb a relatively large amount of liquid quickly from the surface portion where the tip of the striate body is located toward the inner portion. In addition, the pile's independence, flexible elasticity, and performance such as absorption and uptake are maintained over a long period of time.

  (2) FIG. 4 is a schematic front view of a wiping tool as an example of an embodiment of the present invention.

  This wiping tool B has a pile P similar to the above, that is, a pile P whose end side (lower half) has a substantially hemispherical shape (substantially hemispherical portion Pa) and whose base side (upper half) has a substantially cylindrical shape. (The ratio of height / base diameter is approximately 1/1) is densely arranged on one surface (the lower surface in FIG. 4) of the base fabric S (base), and the base of each pile P is the base Bonded to the cloth S.

  The other surface fastener member D for attaching to and detaching from one surface fastener member provided on the lower surface of the mop head (not shown) is provided on the other surface (upper surface in FIG. 4) of the base fabric S. Thus, the wiping tool B can be attached to and detached from the mop head. In addition, the aspect of the wiping tool for mops is not restricted to this. For example, a sheet-like part (which may be a part of the base fabric) that does not have a wiping part on both sides of the wiping part, or that includes an insertion part for inserting both ends of the mop head on the upper surface side and attaching to the mop head The sheet-like part may be provided and held by a holding part provided on the upper side of the mop head and attached to the mop head.

  In each pile P, a strong water absorption force acts toward the core portion W located at the base portion of the axial center line due to capillary action, so that each pile P has the core portion W from the surface portion where the tip end portion of the filament F is located. A relatively large amount of water (water that does not contain dirt or water that contains dirt) can be quickly absorbed along with the dirt if it contains dirt, toward the base of the axial center line. The substantially cylindrical outer peripheral portion of the pile in a state where moisture has been absorbed easily maintains a relatively dry state. Therefore, this wiping tool can be effectively used for wiping and cleaning in a wet state or a dry state, or for wiping water on a cleaning object after washing with water or wet wiping and cleaning.

  In addition, the pile P has high independence with respect to the surface of the base fabric S and is rich in flexibility with respect to pressing, and also the independence and flexibility of the pile P, moisture absorption, and drying of the surface portion. Such performance and wiping and cleaning performance are maintained over a long period of time.

  Further, when the filaments constituting each pile P are non-water-absorbing filaments, the filaments are non-water-absorbing and the filaments F are radially formed around the axis of the pile P. The pile P has a substantially hemispherical shape Pa, and the filaments F are radially arranged to form a substantially convex curved surface. The pile P has a substantially cylindrical outer peripheral surface and a front end portion. Due to the structure that the substantially convex curved surface part is formed by the tip part of each filament F, centrifugal dehydration or other dehydration after drying of each pile of the wiping part, and drying after dehydration Excellent.

  (3) FIGS. 5 and 6 relate to a slipper (an example of footwear) as an example of an embodiment of the present invention, in which FIG. 5 is a schematic longitudinal sectional view, and FIG. 6 is a schematic enlarged cross section. FIG.

  This slipper G has all the parts facing the part where the foot in the worn state is located (that is, the part where the sole, the front part on the back side, the toe part and the front part are located in the state where the slipper G is worn). The base fabric S is composed of a large number of piles P similar to those described above on one surface. That is, the base fabric S is provided on the bottom upper part G1 (including the toe inside lower part G2) and the upper inside G3 (including the toe inside G4, the toe inside upper part G5 and the front inside part G6) of the slipper G. In addition, the pile P in the base fabric S is provided so as to face the portion where the foot in the worn state is located. Needless to say, the footwear of the present invention does not necessarily have to have piles at all the portions facing the portion where the foot in the worn state is located. In addition, as the base fabric, for example, felt, woven fabric, non-woven fabric, knitted fabric, and the like can be used. In addition to the base fabric, a sheet-like material that can be provided with a pile (for example, leather, synthetic resin material, synthetic rubber material, etc.) ) Can be used to construct footwear with piles.

  In each pile P, a strong water absorption force acts toward the core portion W located at the base portion of the axial center line due to capillary action, so that each pile P has the core portion W from the surface portion where the tip end portion of the filament F is located. A relatively large amount of water can be quickly absorbed toward the base of the axial center line. The substantially cylindrical outer peripheral portion of the pile in a state where moisture has been absorbed or the outer peripheral surface portion of the substantially convex curved tip end portion is easily maintained in a relatively dry state, and stickiness is less likely to occur.

  Further, when the filaments constituting each pile P are non-water-absorbing filaments, the filaments are non-water-absorbing and the filaments F are radially formed around the axis of the pile P. The pile P has a substantially hemispherical shape Pa, and the filaments F are radially arranged to form a substantially convex curved surface. The pile P has a substantially cylindrical outer peripheral surface and a front end portion. By virtue of the fact that the substantially convex curved surface portion is formed by the tip portion of each filament F, the outer peripheral surface portion of each pile provided at the portion where the foot in the state where the slipper G is worn is located, Furthermore, it is easy to maintain a dry state, and a sticky feeling is less likely to occur. It is excellent in centrifugal dehydration after washing or other dehydration and drying after dehydration.

  Therefore, when this slipper G is worn, a large number of piles respectively provided on the bottom upper part G1 (including the toe inner lower part G2) and the upper interior G3 (including the toe inner G4, the toe inner upper part G5 and the front inner part G6). P, that is, a large number of piles P facing the part where the sole of the foot, the front part of the instep, the toe part and the front part are located, wets the moisture of the wet foot after bathing, showering, swimming, playing with water, bathing in the sea, etc. Water can be absorbed quickly, and a dry feeling can be quickly given to the foot in the state where the slipper G is worn.

  Moreover, this slipper gives a moderate stimulus to the foot which stepped on the pile P by the independence of the pile P and the flexible elasticity with respect to a press. In addition, this pile mat A can quickly absorb water such as wet feet and the like, and can hardly realize sticky feeling. Maintained over time.

  It should be noted that the dimensions, number, material, shape, relative arrangement, etc. of the component parts in the description of the above embodiments are limited to the scope of the present invention unless otherwise specified.
