  [1] Embodiment of the present invention

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

  The drawings all relate to the treatment pile holder of the present invention, of which FIGS. 1 and 2 are for a water-absorbing pile mat as the treatment pile holder of the present invention, and FIG. 5 is the treatment of the present invention. It is about the cleaning material for the mop as a pile holder for a car.

  1 to 5 are schematic diagrams for explanation, and do not show actual objects.

  (1) The water-absorbing pile mat A includes a rectangular base fabric S (base) having water absorption and a large number of substantially cylindrical large-diameter piles P1 and small-diameter piles P2 (pile for water absorption [treatment]). The large-diameter piles P1 and the small-diameter piles P2 are mounted on the base fabric S in a state where the base portions (lower ends in FIG. 1) of the large-diameter piles P1 and small-diameter piles P2 are coupled to the base fabric S. The rectangular predetermined area X, which is an area in which a large number of large-diameter piles P1 are disposed on the base cloth S, and an area in which a large number of small-diameter piles P2 are disposed on the base cloth S The other areas Y of the rectangular shape are alternately arranged in the longitudinal direction in the plan view of the base fabric S (for example, the predetermined area X, the other area Y, the predetermined area X, the other area Y, the predetermined area X, the other area Y). . The longitudinal lengths of the predetermined area X and the other area Y are the same in width in the short direction of the base fabric S, and the short direction of the predetermined area X and the other area Y is the longitudinal direction of the base cloth S. The predetermined area X is slightly larger in width (width in the short direction) than other areas Y.

  (2) The large-diameter pile P1 and the small-diameter pile P2 in the water-absorbing pile mat A are also collectively referred to as pile P.

  (2-1) Pile P uses two 50-denier polyester filament monofilament yarns as core yarn, and 0.52 denier polyester fiber monofilament F as a decorative yarn (single piece with a central portion held by the core yarn) The strong yarn (500 T / m) of the molding yarn M used as the fiber F) can be formed as follows.

  That is, the strong twist molding yarn M is penetrated from the back side to the front side (upper side in FIG. 4) of the base fabric S (substrate) having water absorption in a tensioned state, so that the strong twist molding is formed on the front side of the base fabric S. The yarn M is projected in a double fold shape (the center and right side in FIG. 4 and the single fiber F is omitted on the right side), and a tensile force is applied in the protruding direction to the folded portion which is the tip of the protruding strong twisted molding yarn M. After maintaining the tension of the strongly twisted molding yarn M protruding in a folded shape, the tensile strength is released, so that the strong twist molding yarn M twists itself and is used for a single pile of water absorption ( Processing pile).

  By heat-treating this, the twisted strong yarn M in a twisted state is twisted more strongly by itself, forming a substantially cylindrical shape with the core yarn C as the center, and the single fibers F are radially formed in a radial direction. It is densely arranged in the direction and becomes denser as it goes inward, and is densely arranged in the axial direction, and the tip portion Pa of the pile P forms a substantially convex curved surface shape by the tip portion of the substantially single filament F. A large number of piles P (left side in FIG. 4) can be formed.

  (2-2) The pile P has an axial length / base diameter ratio of 3/2 to 5/2 and is self-supporting with respect to the surface of the substrate. The pile P does not need to stand upright as shown in FIG. 1 which is a schematic view, and the axial center line standing with respect to the surface of the base is approximately 80 to 90 degrees.

  The outer shape of the pile P has a rotating curved surface shape in which the end portion side is reduced to a substantially spherical shape toward the end portion, and the base portion side is generally along the one having a substantially cylindrical rotating curved surface shape.

  The large-diameter pile P1 has a length of a single fiber F as a decorative yarn of about 12 mm, a diameter of a base cross section (a surface perpendicular to the axis) of about 12 mm, and an axial length of about 24 mm. Those having different axial lengths of about 10 to 20% may be mixed.

  In the small-diameter pile P2, the length of the single fiber F as the decorative yarn is about 6 mm, the diameter of the base cross section (plane orthogonal to the axis) is about 6 mm, and the axial length is about 17 mm. Those having different axial lengths of about 10 to 20% may be mixed.

  (2-3) Each pile P whose base is bonded to the base fabric S has a substantially cylindrical shape from the base to the tip, and is made of monofilament yarns of hydrophobic fibers (fibers with poor water absorption) along the axis. A single fiber F consisting of a large number of very thin polyester fibers of 0.52 denier (hydrophobic fiber having a water absorption of 5% or less at 20 ° C. and 65% relative humidity [fiber having poor water absorption]. The same shall apply hereinafter), and the cylinder P is held in a state of being densely arranged radially in the radial direction about the axis of the pile P and being densely arranged in the axial direction. It is formed by the tip of the fiber F.

  The tip portion Pa of the pile P is formed by a large number of single fibers F of 0.52 denier polyester fibers that are held tightly by the core yarn C so as to form a radial shape, and has a substantially convex curved shape. The curved surface part is formed by the tip part of those single fibers F.

  The core yarn C along the axis of the pile P is composed of two 50 denier monofilament yarns of polyester fibers (hydrophobic fibers having a water absorption of 5% or less at 20 ° C. relative humidity of 65%, the same applies hereinafter). ing.

  (2-4) At the tip end Pa of the pile P, the ultrafine hydrophobic single fiber F is three-dimensionally inward (for example, the center of the bottom of the substantially hemisphere if it is an upwardly convex substantially hemisphere). In the substantially cylindrical portion other than the tip portion Pa, the density of the ultrafine hydrophobic single fiber F increases in the radially inward direction and becomes stronger in the capillary phenomenon. Water absorption acts. Therefore, each pile P can absorb a relatively large amount of water quickly inward in the radial direction.

  Conversely, the substantially convex curved outer peripheral portion of the tip portion Pa of the pile P that has absorbed water and the substantially cylindrical outer peripheral portion of the pile P are in a state of low moisture content due to capillary action. In other words, the substantially convex curved outer peripheral portion of the tip portion Pa of the pile P and the substantially cylindrical outer peripheral surface portion of the pile P are formed by the tip portion of the single fiber F of the hydrophobic fiber, so the area occupied by the fibers is compared. And the fibers themselves remain non-wetting.

  (3) A large number of large-diameter piles P1 having an axial length of about 20 to 24 mm are arranged in the predetermined area X, and another area Y adjacent to the predetermined area X in the longitudinal direction of the base fabric S. A large number of small-diameter piles P2 having an axial length of about 12 to 15 mm are arranged.

  The large-diameter pile P1 constituting the pile group disposed in the predetermined area X has a substantially cylindrical shape of all the piles as compared with the small-diameter pile P2 constituting the pile group disposed in the adjacent other area Y. The area of the cross section of the part is about 4 times.

  The large diameter pile P1 constituting the pile group arranged in the predetermined section X and the small diameter pile P2 constituting the pile group arranged in the adjacent other section Y both have an axial length / base diameter ratio. 3/2 to 5/2 and has self-supporting property with respect to the surface of the substrate. Further, the large-diameter pile P1 has a relatively large supporting force in the axial direction.

  The pile group arranged in the other area Y adjacent to the predetermined area X has a small diameter pile P2 having a self-supporting property but a relatively small cross-sectional area with respect to a portion where the unevenness and undulation of the object are relatively large. Can be processed effectively while spreading throughout the details.

  The small-diameter pile P2 constituting the pile group disposed in the other area Y adjacent to the predetermined area X has a relatively small cross-sectional area, so that its independence is relatively easily lost. The pile group composed of the large-diameter piles P1 can effectively support the object in the axial direction, so that the self-supporting property is easily maintained even though the cross-sectional area is relatively small. The processing for a portion with a relatively large change such as the above can be performed satisfactorily including details.

  (4) The mop cleaning material B shown in FIG. 5 is provided with a large number of piles P on one surface of the base fabric S, and a mop head (see FIG. 5) on the other surface (upper surface in FIG. 5). (Not shown) Except for the point that the other surface fastener member D for attaching to and detaching from one surface fastener member provided on the lower surface of the lower surface, the size in plan view, and the number of the predetermined area X and other area Y, The basic structure is the same as the water-absorbing pile mat shown in FIGS. In addition, the aspect of the cleaning material for mops is not restricted to this. For example, a sheet-shaped portion (which may be a part of the base fabric) that does not have piles P on both sides of the cleaning material, or one having an insertion portion 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.

  [2] Embodiments of the present invention will be further described, including forms other than those described above.

  Embodiments of the processing pile holder of the present invention will be further described, including forms other than those described above.

  (1) The processing pile holder of the present invention comprises a base and a number of processing piles, and the plurality of piles are disposed on the base with the base of each pile being bonded to the base. And a plurality (preferably 3 or 4 or more) of areas in which a large number of processing piles are arranged on the substrate.

  (1-1) The substrate in the treatment pile holder of the present invention is generally a base fabric (for example, woven fabric, non-woven fabric, felt, knitted fabric, etc.), but is not necessarily limited thereto. A sheet-like material (for example, leather, a synthetic resin material, a synthetic rubber material, or the like) or other materials can be used.

  (1-2) The processing pile is a pile having a substantially cylindrical shape with a free end at a tip end, and a large number of fiber-made linear bodies are radial in the radial direction about the axis of the pile. And are densely arranged in the axial direction.

  (a) The fact that a large number of fiber linear bodies are radially radial about the axis of the pile does not mean that they must be radially linearly geometrically radial. However, it is only necessary that the linear body made of fibers is generally radial in the radial direction and becomes more dense as it goes inward.

  The pile may have a substantially convex curved surface with a linear body made of fibers arranged radially.

  (b) Such a pile is formed by, for example, holding a linear filament made of fiber with a core yarn and turning one piece of the yarn thread as a decorative yarn back into two pieces, and centering the core yarn of each piece of the mole yarn And the twisted portion forms one mole yarn-like substantially cylindrical pile with the folded portion as the tip portion, and the tip portion has a substantially radial shape from the folded portion of the core yarn. A substantially convex curved surface can be formed by the tip of the fiber-like linear body densely arranged. Further, the surface portion of the outer shape of the pile may be formed by the tip portion of the linear body except the base side of the base portion of the pile.

  (c) A large number of fiber linear bodies held by the core yarn are held by the core yarn at an intermediate portion thereof. Those fiber-made linear bodies can be basically independent from each other except for the portion held by the core yarn. It is desirable that the intermediate portion held by the core yarn of the fiber linear body is a fixed position in the length direction of the fiber linear body, particularly the center position.

  (d) Examples of the holding of the fiber linear body with respect to the core yarn include holding by a force sandwiched between a plurality of core yarns (for example, between a plurality of core yarns in a twisted state). 1 or, preferably, holding by fixing force of a fixing substance such as adhesion or fusion to two or more core yarns, or a combination of both (the force sandwiched between a plurality of core yarns and the fixing force of the fixing material) Can be used together).

  In the case of holding the fixing substance by the fixing force, for example, a heat-sealing yarn is used as the core yarn, and the core yarn can be fused by heat treatment.

  (e) Examples of the core yarn include, but are not limited to, a 10 to 300 denier monofilament yarn, a spun yarn, or a multifilament twisted yarn. The heat fusing yarn can also be used. Examples of the core yarn material include, but are not limited to, polyester fibers, polypropylene fibers, polyethylene fibers, and polyamide fibers.

  (1-3) For example, monofilaments, synthetic fibers, or natural fiber staple yarns may be used as the fiber filaments in the treatment pile.

  (a) A monofilament having a poor water absorbability of 0.03 to 3 denier is preferable as the filamentous filament in the treatment pile. The fineness of the single fiber having poor water absorption is more preferably 0.05 to 2 denier, still more preferably 0.1 to 1.5 denier, 0.1 or 0.2 to 1.2 denier, and. It may be 1 or 0.2 to 1 denier, or 0.1 or 0.2 to 0.8 denier.

  By making the monofilament as a fiber filament in the treatment pile poor in water absorption, in the treatment pile, water absorption force directed inward due to capillary action can act. .

  A large number of single fibers are densely arranged in the circumferential direction so as to form a radial shape about the axis of the processing pile and are densely arranged in the axial direction so as to go inward, and the density increases. Is a single fiber with a poor water absorption of 0.03 to 3 denier, and due to capillarity, a strong water-absorbing force acts inwardly, and a relatively large amount of water is rapidly inward. Can absorb water.

  The outer peripheral portion of the treatment pile that has absorbed water in this way is in a state where the moisture content is low due to capillary action, and the outer peripheral surface portion is formed by the tip portion of a single fiber having poor water absorption, The area occupied by the fibers is relatively small, and the fibers themselves remain non-wetting. Therefore, the outer peripheral surface portion in a state where moisture has been absorbed is easily maintained in a relatively dry state, and a sticky feeling is less likely to occur.

  (b) The length of the single fiber can be, for example, 3 to 30 mm, but is not limited thereto. Further, the length of the single fiber is preferably constant, but is not limited thereto.

  (c) The water absorption rate of the single fiber having poor water absorption can be, for example, 5% or less at 20 ° C. and 65% relative humidity. Preferably, it is 3% or less, more preferably 2% or less, and further preferably 1% or less at 20 ° C. and 65% relative humidity. As such a single fiber, it can consist of filaments, such as a polyester-type fiber, a polypropylene-type fiber, a polyethylene-type fiber, a polyamide-type fiber, for example, and if necessary, all the single fibers or some single fibers Can be crimped such as crimped filaments, or the whole or part of all single fibers or some single fibers can be hydrophilized with various surfactants or the like.

  (d) The single fiber as the fiber filament in the treatment pile is, for example, about 10,000 to 250,000 per 1 cm in the axial direction length of the treatment pile (depending on the fineness of the single fiber, The number of fibers can be small and large, respectively.If the single fiber is 0.7 denier, for example, about 50,000 pieces per 1 cm of the axial length of the pile for processing) is about the axis. It can be densely arranged radially in the radial direction and densely arranged in the axial direction.

  (e) The single fibers as the fiber filaments in the treatment pile may be in a state where they are not twisted together. Since the single fibers are not twisted together, it is difficult to prevent a strong water absorption from acting inward in the radial direction due to capillary action.

  (1-4) Among a plurality of areas in which a large number of processing piles are disposed on the substrate, any one or more predetermined areas are adjacent to other areas, and the piles disposed in the predetermined areas The piles that make up the group are, on average (or all of the piles) compared to the piles that make up the piles arranged in other adjacent areas. Is 40% or more, the ratio of axial length / base diameter is 1/2 (or 3/5) to 4/1, and the supporting force in the axial direction is relatively large. When the ratio of the axial length / base diameter is 1/2 (or 3/5) to 3/1 (or 14/5), the pile has a relatively large supporting force in the axial direction and is on the surface of the substrate. However, it tends to be self-supporting.

  (a) A plurality of areas in which a large number of piles for processing are arranged on the substrate are, for example, those having the same shape and the same area, respectively, and predetermined areas and other areas are adjacent to each other alternately in a certain direction ( You can list things that are lined up with the same width or with different widths of the predetermined area and other areas, those where the predetermined area is surrounded by other areas, those where the predetermined area surrounds other areas, etc. It is not limited to. A plurality of processing piles are arranged on a substrate, for example, in a straight line, a curved line, or a wave shape (for example, a sine wave shape, a triangular wave shape, a rectangular wave shape, a sawtooth wave shape) or in a staggered arrangement. Can be configured.

  It does not require that anything other than the pile exists between the plurality of areas as a delimiter or that a delimiter is drawn.

  The plurality of areas may be separated along a straight line in a certain direction, but the present invention is not limited to this.

  There may be piles of different heights (or other dimensions) in one area. Further, a plurality of regions made of piles having different heights (or other dimensions) may exist in one area.

  (b) The predetermined area is adjacent to another area, and the piles constituting the pile group arranged in the predetermined area are on average compared to the piles constituting the pile group arranged in the other adjacent area. (Or all the piles), the area of the cross section of the substantially cylindrical portion is 40% or more larger (preferably 2 to 10 times, more preferably 3 or 4 to 9 times), and the axial length / Base diameter ratio is 1/2 to 4/1.

  (c) Of the piles for processing, the ratio of the length in the axial direction / the diameter of the base is 1/2 to 3/1 and has a self-supporting property with respect to the surface of the substrate. As the axial center line, an axial center line perpendicular to the surface of the base body is most desirable, but, for example, about 60 to 90 degrees, or about 70 degrees or about 80 to 90 degrees with respect to the surface of the base body. Can be mentioned.

  As an example of the outer shape of a pile having an axial length / base diameter ratio of 1/2 to 4/1 (or 3/1), a rotating curved surface whose end side is reduced to a substantially spherical shape toward the end The base portion side has a substantially cylindrical rotating curved surface shape, and the base portion side has a rotating curved surface shape whose diameter decreases from the base portion toward the end portion into a substantially spherical shape.
