Description

  The present invention relates to a loop pile mat, a wiping cloth for cleaning, footwear or other aspects of a loop pile holder in which a loop pile having self-supporting properties is disposed on a base.

  Japanese Patent Application Laid-Open No. 2008-73173 (Patent Document 1) states that “a plurality of piles are provided on a base fabric in a state in which a base fabric and a plurality of piles are provided and a base portion of each pile is coupled to the base fabric. Each pile has a substantially cylindrical shape, and a non-water-absorbing filament of 0.05 to 0.8 denier is radially radially about the axis of the pile. A highly water-absorbing and highly-drying pile mat, wherein the pile has a substantially cylindrical outer peripheral surface formed by a tip portion of each filament. Is disclosed.

  A large number of piles arranged on the pile mat base fabric are such that very thin non-water-absorbing filaments of 0.05 to 0.8 denier radiate substantially radially about the pile axis. Because the filaments are densely arranged in the axial direction, the filaments become denser toward the inside in each circular cross section of the substantially cylindrical pile. Since a strong water-absorbing force acts toward the inside of the pile, each pile can quickly absorb a relatively large amount of water toward the inside of each circular cross section.

  On the contrary, the substantially cylindrical outer peripheral portion, which is the outer portion of each circular cross section in the water-absorbed pile, has a low moisture content due to capillary action. In other words, the substantially cylindrical outer peripheral surface portion of the substantially cylindrical pile is formed by the tip of the non-water-absorbing filament, so that the area occupied by the fiber is relatively small and the fiber itself maintains a non-wetting state. To do. Therefore, the substantially cylindrical outer peripheral 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.

  In addition, the material that the filaments constituting each pile are non-water-absorbing, and the filaments are densely arranged radially in the radial direction around the axis of the pile and densely arranged in the axial direction. The cylindrical outer peripheral surface is excellent in centrifugal dewaterability or other dewaterability and dryness after dehydration, as compared with the structure in which the cylindrical outer peripheral surface is formed by the tip of each filament.

However, the pile in the pile mat has room for improvement in terms of improvement and maintenance of self-supporting property and elasticity, and absorption and uptake of various substances.
JP 2008-73173 A

  The present invention has been made in view of the above-described problems existing in the prior art, and the object of the present invention is to have independence and flexible elasticity, and to absorb and incorporate various substances. An object of the present invention is to provide a loop pile holder that can improve and maintain performance.

(1) The loop pile holder of the present invention that achieves the above object is
A loop pile holder comprising a base and a loop pile, wherein the loop pile is disposed on the base in a state where the base is coupled to the base,
The loop pile forming yarn forming the loop pile has a substantially cylindrical shape, and 0.05 to 0.8 denier non-water-absorbing filaments are radially formed around the axis of the loop pile forming yarn. So that the cylindrical outer peripheral surface is formed by the tip of the filament,
The loop pile has a ratio of (loop pile height) / (loop pile forming yarn diameter) of 1/1 to 5/1 and (distance between centers of both bases of the loop pile) / (loop pile). The ratio of the diameter of the formed yarn) is 3/1 or less, and is self-supporting with respect to the surface of the substrate.

  The loop pile forming yarn that forms a loop pile disposed on the base with the base bonded to the base has a substantially cylindrical shape and is a very thin non-water-absorbing filament of 0.05 to 0.8 denier Is densely arranged radially in the radial direction about the axis of the loop pile forming yarn and is densely arranged in the axial direction, and the substantially cylindrical outer peripheral surface is formed by the tip of the filament. Therefore, in each circular cross section of the loop pile forming yarn having a substantially columnar shape, the filament becomes more dense as it goes inward.

  The loop pile is formed of such a loop pile forming yarn, and the ratio of (the height of the loop pile) / (the diameter of the loop pile forming yarn) is 1/1 to 5/1 and The ratio of the distance between the centers of both base portions / (the diameter of the loop pile forming yarn) is 3/1 or less. This loop pile is supported on the base by a large number of filaments at both bases, and the piles rising from both bases are connected in a loop, and the height is lower than the diameter of the loop pile forming yarn. By these synergistic effects, it has very good self-supporting property and flexible elasticity against pressing in the height direction of the loop pile.

  Further, this loop pile is excellent in performance of absorbing and taking in various substances. That is, the density of the filament in the loop pile increases as it goes from the surface portion of the loop pile forming yarn to the inner portion, and a strong liquid absorption force acts toward the inner portion of the loop pile forming yarn due to capillary action. A loop pile is a relatively large amount of liquid (contains no dirt or other substances or contains dirt or other substances) quickly from the surface part where the tip of the filament is located toward the inner part of the loop pile forming yarn. Water or other liquid that is simply referred to as "water" or "moisture" or "liquid" or "liquid"). However, the elasticity of the loop pile and the performance such as absorption and uptake are maintained for a long time due to the good self-supporting property of the loop pile.

  Conversely, the surface portion of the loop pile forming yarn that has absorbed water is in a state of low moisture content due to capillary action. Since the surface portion of the loop pile forming yarn is formed by the tip of the non-water-absorbing filament, the area occupied by the fiber is relatively small, and the fiber itself maintains a non-wetting state. Therefore, the substantially cylindrical outer peripheral portion of the loop pile in a state where moisture has been absorbed is easy to maintain a relatively dry state, and a sticky feeling is unlikely to occur.

(2) The loop pile holder of the present invention is
A loop pile holder comprising a base and a loop pile, wherein the loop pile is disposed on the base in a state where the base is coupled to the base,
The loop pile forming yarn forming the loop pile has a substantially cylindrical shape, and 0.05 to 0.8 denier non-water-absorbing filaments are radially formed around the axis of the loop pile forming yarn. So that the cylindrical outer peripheral surface is formed by the tip of the filament,
The loop pile has a ratio of [(the length of the loop pile forming yarn) − (the distance between the centers of both bases of the loop pile)] / (the diameter of the loop pile forming yarn) of 1/1 to 10/1. The ratio of (distance between the centers of both bases of the loop pile) / (diameter of the loop pile forming yarn) is 3/1 or less, and is self-supporting with respect to the surface of the substrate. .

  The loop pile in this case has a ratio of [(length of loop pile forming yarn) − (distance between centers of both bases of loop pile)] / (diameter of loop pile forming yarn) of 1/1 to 10/1. And the ratio of (distance between centers of both bases of the loop pile) / (diameter of loop pile forming yarn) is 3/1 or less.

  Therefore, similar to the above-described invention of the loop pile holder, the loop pile is supported on the base by a large number of filaments at both bases, and the piles rising from both bases are connected in a loop shape. Since the height is lower than the diameter of the formed yarn, these synergistic effects provide extremely good self-supporting property and flexible elasticity against pressing in the height direction of the loop pile. The other points are the same as the invention of the loop pile holder.

  (3) In each of the loop pile holders, the loop pile forming yarn alternately penetrates the surface of the substrate and the back side thereof, forms a loop pile on the surface side of the substrate, and forms a seam on the back surface side. It can be.

  In this case, on the surface side of the substrate, a loop pile is formed by loop pile forming yarns that are supported on the substrate by a large number of filaments at both bases, and piles rising from both bases are connected in a loop shape.

  (4) Each of the loop pile holders is such that the filaments at both base portions of the loop pile are inclined parallel to the surface of the substrate or outward from the axis of the loop pile forming yarn, or toward the surface of the substrate. It is preferable to extend in a shape.

  In this case, the filaments at both bases of the loop pile extend outward from the axis of the loop pile forming yarn in parallel to the surface of the base or in an inclined shape toward the surface of the base, thereby Has the function of standing up and supporting.

  (5) In the loop pile forming yarn, two or three or more molding yarns having a non-water-absorbing filament of 0.05 to 0.8 denier as a decorative yarn are twisted around the core yarn of the molding yarn. By combining them, a substantially cylindrical shape can be formed.

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

  (7) The water absorption rate of the non-water-absorbing filament may be 5% or less at 20 ° C. and 65% relative humidity.

  (8) Each of the loop pile holders of the present invention may be formed by arranging a large number of the loop piles on a base.

  (9) Each of the loop pile holders according to the present invention has a loop pile formed on a loop surface formed by loop pile forming yarns in at least a part of the loop pile group of the loop piles arranged on the substrate. It is possible to be in close contact with the vertical direction, which is the direction along, and close to the horizontal direction, which is a direction perpendicular to the loop surface.

  In this case, the loop piles are in close contact with each other in the longitudinal direction, which is a direction along the loop surface formed by the loop pile forming yarn, and in close contact in the lateral direction, which is a direction perpendicular to the loop surface, thereby making the loop piles It is possible to improve the elasticity of the sword and its flexibility against the pressing in the height direction. In addition, since the loop piles in a state where the side surface portion of the loop pile forming yarn is positioned on the upper side in the height direction are arranged in close contact with each other, the density of the filament is increased, and a stronger liquid absorption force can be exhibited.

  (10) The base body in each loop pile holder of the present invention may be a base fabric.

  The loop pile holder according to the present invention has a self-supporting property, and a loop pile is provided on the substrate, which is based on the self-supporting property and is capable of improving and maintaining elasticity and absorption and uptake performance of various substances.

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

  (1) FIGS. 1 to 5 all relate to a loop pile mat as an example of an embodiment of the present invention. FIG. 1 is a schematic front view, FIG. 2 is a schematic side view, and FIG. 4 is a schematic plan view, FIG. 4 is a schematic bottom view, and FIG. 5 is a schematic enlarged cross-sectional view of a loop pile forming yarn.

  The loop pile forming yarn T forming the loop pile P of the loop pile mat A is composed of two molding yarns having a non-water-absorbing polyester filament F of 0.3 denier as a decorative yarn, and the core yarn C of the molding yarn C The filaments F are densely arranged so as to form a radial shape about the axis of the loop pile forming yarn T and are densely arranged in the axial direction. The substantially cylindrical outer peripheral surface is formed by the tip of the filament F.

  The core yarn C can be a water absorbent yarn and / or a non-water absorbent yarn. In the case of a molding yarn in which a 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 dropping off with high certainty.

  This loop pile forming thread T penetrates through the base fabric S from one end of one seam H on the back side of the base fabric S, and protrudes from the through hole to the surface side to form a loop pile P. From the same through hole, the base fabric S Returning to the back side of S, the next one seam H is formed. The loop pile forming thread T again penetrates the base fabric S from the other end of the seam H, protrudes to the surface side from the through hole to form a loop pile P, and returns to the back side of the base fabric S from the same through hole. The next one seam H is formed. In this way, the surface of the base fabric S (base body) and the back side thereof are alternately passed through, the loop pile P is formed on the surface side of the base fabric S, and the seam H is formed on the back side. The loop surface [surface along the loop] of the loop pile P formed by the loop pile forming yarn T is along the horizontal direction in FIG. 3 (and FIG. 4), and the seam H is the front and rear in FIG. 4 (and FIG. 3). It extends in the direction. That is, the loop surface of the loop pile P is orthogonal to the direction of the seam H. Therefore, the loop pile row R by the loop pile P continuously formed by the loop pile forming yarn T is orthogonal to the longitudinal direction of the loop pile P (direction along the surface along the loop [left and right direction in FIG. 1]). A large number of loop piles P are arranged on a straight line (not necessarily a straight line) in the horizontal direction (left and right direction in FIG. 2).

  By providing a large number of such loop pile rows R in parallel, a large number of loop piles P are arranged vertically and horizontally on the surface of the base fabric S, and a large number of rows of seams H are arranged in parallel on the back side of the base fabric S. State. The row of seams H on the back side of the base fabric S can be backed with latex to ensure the fixing to the base fabric, and the bottom cover is used to prevent slipping and improve durability. (It may be a mesh ground). Further, in the loop pile mat A of this example, adjacent loop pile rows R are arranged in parallel in the same phase, but can be shifted by, for example, a half wavelength, a quarter wavelength, or any other manner. . Further, in the loop pile mat A of this example, all the loop piles P are formed substantially the same, but a plurality of types of loop piles P are provided for each loop pile row R or in another manner. You can also. Furthermore, the loop surface of the loop pile is made parallel to the direction of the seam, and the loop pile forming yarn T returns to the back side through another hole and a hole penetrating the base fabric to form the loop pile. You can also

  Each loop pile P has a ratio of (the height of the loop pile P) / (the diameter of the loop pile forming yarn T) of about 2/1 and (the distance between the centers of both bases of the loop pile P) / (loop The ratio of the diameter of the pile forming yarn T is about 1/3 and [(the length of the loop pile forming yarn T) − (the distance between the centers of both bases of the loop pile P)] / (the loop pile forming yarn T) When the ratio of (diameter) is about 3/1, the surface of the base fabric S has good self-supporting properties. The filaments F at both bases of the loop pile P are parallel to the surface of the base fabric S or inclined toward the surface of the base fabric S from the axial center of the loop pile forming yarn T outward. It has a function of extending and supporting the loop pile P upright.

  The loop piles P are in close contact with each other in the vertical direction and in close contact with the lateral direction (the left-right direction in FIG. 2) that is a direction orthogonal to the loop surface. As an example of such a state, in the longitudinal direction, in the state where each loop pile P is self-supporting, the interval between adjacent loop piles P is 1/2 to −1/2 of the diameter of the loop pile forming yarn T (minus 1). / 2. A state in which one half of the diameter overlaps.). Preferably it is 1/4 to -1/2 (or -1/4), more preferably 0 to -1/2 (or -1/4). At least a state in which the loop piles P are in contact with each other in a state of being pressed in the height direction to maintain the standing state is preferable. In the lateral direction, in the state where each loop pile P is self-supporting, the interval between adjacent loop piles P is 1/2 to -1/2 of the diameter of the loop pile forming yarn T (a state in which one half of the diameter overlaps). There are certain states. Preferably it is 1/4 to -1/2 (or -1/4), more preferably 0 to -1/2 (or -1/4).

  The loop pile forming yarn T that forms the loop pile P disposed on the base fabric S in a state where the base portion is bonded to the base fabric S has a substantially cylindrical shape and is extremely thin non-water-absorbing of 0.3 denier. The filament F is densely arranged radially in the radial direction about the axis of the loop pile forming yarn T and is densely arranged in the axial direction, and the substantially cylindrical outer peripheral surface is the tip of the filament F. Therefore, in each circular cross section of the loop pile forming yarn T having a substantially cylindrical shape, the filament F becomes more dense as it goes inward.

  The loop pile P is formed by such a loop pile forming yarn T, and has the self-supporting property with respect to the surface of the base fabric S as described above, and the surface of the base fabric S by a large number of filaments F at both base portions. Are piled up from both bases and connected in a loop, and the height is lower than the diameter of the loop pile forming yarn T. It has flexible elasticity against the pressure in the height direction of the loop pile P.

  Further, the loop pile P is excellent in performance of absorbing and taking in various substances. That is, the density of the filament F in the loop pile P becomes higher from the surface portion of the loop pile forming yarn T toward the inner portion, and strong liquid absorption force toward the inner portion of the loop pile forming yarn T due to capillary action. Therefore, the loop pile P rapidly moves from the surface portion where the tip of the filament F is located toward the inner portion of the loop pile forming yarn T, and does not contain a relatively large amount of liquid (contains dirt or other substances or Water or other liquids containing dirt or other substances may simply absorb "water" or "moisture" or "liquid" or "liquid"). In addition, due to the good independence of the loop pile P, flexible elasticity and performance such as absorption and uptake are maintained for a long time.

  On the contrary, the surface portion of the loop pile forming yarn T that has absorbed water has a low moisture content due to capillary action. Since the surface portion of the loop pile forming yarn T is formed by the tip portion of the non-water-absorbing filament F, the area occupied by the fiber is relatively small, and the fiber itself maintains a non-wetting state. Therefore, the substantially cylindrical outer peripheral portion of the loop pile P in a state where moisture has been absorbed is easy to maintain a relatively dry state, and a sticky feeling is unlikely to occur.

  The non-water-absorbing 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 water absorption rate of the non-water-absorbing filament F can be, for example, 5% or less at 20 ° C. and 65% relative humidity.

  The height of the loop pile can be 3 to 30 mm, for example. The thickness is preferably 5 to 20 mm, more preferably 5 to 15 mm. The diameter of the loop pile forming yarn can be set to 2 to 30 mm, for example. The thickness is preferably 3 to 20 mm, more preferably 4 to 15 mm.

  In addition to the base fabric (for example, felt, woven fabric, non-woven fabric, knitted fabric), for example, a sheet-like material (for example, leather, synthetic resin material, synthetic rubber material, etc.) on which a loop pile P can be provided is used. Can do.

  The loop pile holder of the present invention includes, for example, a loop pile mat (for foot wiping, water absorption or other use mat, kitchen mat, etc.), footwear such as slippers, cleaning tools such as wiping cloth, various furniture, etc. Or it can be used as a part thereof.

  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.
