[1] Embodiment of the present invention

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

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

It should be noted that FIGS. 1 to 5 are schematic views for explanation, and do not show the actual product.

(1) The water-absorbing pile mat A consists of a water-absorbing rectangular base cloth S (base) and a large number of substantially cylindrical large-diameter piles P1 and small-diameter piles P2 (water-absorbing [treatment] piles). In preparation, the large number of large-diameter piles P1 and small-diameter piles P2 are placed on the base cloth S in a state where the bases (lower end portions in FIG. 1) of the large-diameter piles P1 and the small-diameter piles P2 are bonded to the base cloth S. A rectangular predetermined area X, which is an area in which a large number of large-diameter piles P1 are arranged on the base cloth S, and an area in which a large number of small-diameter piles P2 are arranged on the base cloth S. The rectangular other areas Y are alternately provided in the longitudinal direction in the plan view of the base cloth S (for example, predetermined area X, other area Y, predetermined area X, other area Y, predetermined area X, other area Y). .. The lengths of the predetermined area X and the other area Y in the longitudinal direction are the same as each other in the lateral width of the base cloth S, and the lateral directions of the predetermined area X and the other area Y are the longitudinal directions of the base cloth S. The width (width in the lateral direction) of the predetermined area X is slightly larger than that of the other area 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) The pile P uses two monofilament yarns of 50 denier polyester fibers as core yarns and a single fiber F of 0.52 denier polyester fibers as a decorative yarn (a single yarn in which the central portion is held by the core yarns). It can be formed as follows by the strong twist (500 T / m) molding yarn M used as the fiber F).

That is, by penetrating the strong twist molding yarn M from the back side to the front side (upper side in FIG. 4) of the base cloth S (base) having water absorption in a state where tension is applied, the strong twist molding is formed on the front side of the base cloth S. The yarn M is projected in a double-folded shape (center and right side in FIG. 4; the single fiber F is omitted on the right side), and the tensile force is applied in the direction of protrusion with respect to the folded portion which is the tip of the projected strong twist molding yarn M. To maintain the tension of the strong-twisted molding yarn M protruding in a double-folded shape, and then release the tensile force, the strong-twisted molding yarn M twists itself to absorb water in the form of one pile. It becomes a pile (for processing).

By heat-treating this, the strongly twisted molding yarn M in the twisted state is twisted by itself even more strongly, forming a substantially cylindrical shape centered on the core yarn C, and the circumference of the single fiber F so as to form a radial shape in the substantially radial direction. It is densely arranged in the direction and becomes denser toward the inside and is densely arranged in the axial direction, and the tip Pa of the pile P has a substantially convex curved surface shape due to the tip Pa of the substantially radial single fiber 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 to the surface of the substrate. The pile P does not need to stand upright as shown in FIG. 1, which is a schematic diagram, and the axis line standing upright with respect to the surface of the substrate is approximately 80 to 90 degrees.

The outer shape of the pile P has a rotating curved surface whose diameter is reduced toward the end in a substantially spherical shape, and the base side generally follows a rotating curved surface having a substantially cylindrical shape.

The large-diameter pile P1 has a length of a single fiber F as a decorative thread of about 12 mm, a diameter of a base cross section (a surface orthogonal to the axis) of about 12 mm, and a length in the axial direction of about 24 mm. It is also possible to mix those having different axial lengths by about 10 to 20%.

The small-diameter pile P2 has a length of a single fiber F as a decorative thread of about 6 mm, a diameter of a base cross section (a surface orthogonal to the axis) of about 6 mm, and a length in the axial direction of about 17 mm. It is also possible to mix those having different axial lengths by about 10 to 20%.

(2-3) Each pile P whose base is bonded to the base cloth S has a substantially cylindrical shape from the base to the tip, and is made of monofilament yarn of hydrophobic fibers (fibers having poor water absorption) along the axis. A single fiber F (a hydrophobic fiber having a water absorption rate of 5% or less at 20 ° C. and a relative humidity of 65% [fiber having poor water absorption], which is composed of a large number of filaments of extremely fine polyester fibers of 0.52 denier by the core yarn C. (The same shall apply hereinafter) is held in a state of being densely arranged so as to form a radial pattern in the radial direction about the axis of the pile P and being densely arranged in the axial direction, and the substantially cylindrical outer peripheral surface portion of the pile P is simply formed. It is formed by the tip of the fiber F.

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

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

(2-4) In the tip Pa of the pile P, the ultrafine hydrophobic single fiber F is three-dimensionally directed inward (for example, in the case of an upwardly convex substantially hemisphere, the central portion of the bottom surface of the substantially hemisphere). The density of the ultrafine hydrophobic single fiber F increases inward in the radial direction in the substantially cylindrical portion other than the tip Pa, which is stronger due to the capillary phenomenon. Water absorption works. Therefore, each pile P can rapidly absorb a relatively large amount of water inward in the radial direction.

On the contrary, the substantially convex curved outer peripheral portion of the tip Pa of the water-absorbed pile P and the substantially cylindrical outer peripheral portion of the pile P are in a state of low water content due to the capillary phenomenon. Since 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 portions of the single fibers F of the hydrophobic fibers, the areas occupied by the fibers are compared. It is small and the fiber itself maintains a non-wet state.

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

The large-diameter pile P1 constituting the pile group arranged in the predetermined area X has a substantially cylindrical shape of all piles as compared with the small-diameter pile P2 forming the pile group arranged in the other adjacent area Y. The cross-sectional area of the portion is about four times larger.

The large-diameter pile P1 constituting the pile group arranged in the predetermined area X and the small-diameter pile P2 forming the pile group arranged in the other adjacent area Y both have an axial length / base diameter ratio. It is 3/2 to 5/2 and has independence on the surface of the substrate. Further, the large diameter pile P1 has a relatively large bearing capacity 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 that is self-supporting but has a relatively small cross-sectional area with respect to a portion where changes such as unevenness and undulations of the object are relatively large. Can be processed effectively while permeating the details.

The small diameter pile P2 constituting the pile group arranged in the other area Y adjacent to the predetermined area X has a relatively small cross-sectional area, so that the independence is relatively easily impaired, but the small diameter pile P2 is arranged in the predetermined area X. Since the pile group consisting of the large-diameter pile P1 can effectively support the object in the axial direction, the independence is easily maintained even though the cross-sectional area is relatively small, and the unevenness and undulations of the object are easily maintained. It is possible to satisfactorily perform processing on a part where there are relatively many changes such as, including details.

(4) In the mop cleaning material B shown in FIG. 5, a large number of piles P are provided on one surface of the base cloth S, and a mop head (upper surface in FIG. 5) is provided on the other surface of the base cloth S (FIG. 5). Except for the point that the other surface fastener member D for attaching / detaching to / from one surface fastener member provided on the lower surface of (not shown) is provided, the size in a plan view, and the number of predetermined areas X and other areas Y. The basic configuration is the same as that of the water-absorbing pile mat shown in FIGS. 1 and 2. The mode of the cleaning material for the mop is not limited to this. For example, one having an insertion portion for inserting both ends of the mop head on the upper surface side and attaching the mop head to the mop head, or a sheet-like portion (which may be a part of the base cloth) having no pile P on both sides of the cleaning material. The sheet-shaped portion may be held by a holding portion 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 embodiments other than the above.

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

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

(1-1) The substrate in the processing 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 always limited to this, for example, pile. A sheet-like material (for example, leather, synthetic resin material, synthetic rubber material, etc.) or other material can be used.

(1-2) The pile for processing is a pile having a substantially cylindrical shape with a free end at the tip, and a large number of fiber linear bodies radiate substantially in the radial direction around the axis of the pile. It is densely installed so as to form a structure and is densely installed in the axial direction.

(a) The fact that a large number of fibrous striatum radiates approximately radially around the axis of the pile does not mean that they must be geometrically linearly radial in the radial direction. It suffices that the linear body made of fiber is substantially radial in the radial direction and becomes denser toward the inside.

The tip of this pile can be formed into a substantially convex curved surface shape by a linear body made of fibers arranged radially.

(b) In such a pile, for example, a single yarn of a molding yarn in which a linear body made of fiber is held by a core yarn and used as a decorative yarn is folded back into two yarns, and the core yarn of each of the molding yarns is centered. The twisted portion forms a substantially cylindrical pile in the shape of a molding yarn with the folded portion as the tip portion, and the tip portion is substantially radial from the folded portion of the core yarn. A substantially convex curved surface can be formed by the tip portion of a linear body made of fiber which is densely arranged so as to form a sword. Further, the outer surface portion of the outer shape of the pile may be formed by the tip end portion of the striatum except for the substrate side of the base portion of the pile.

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

(d) As for the holding of the fiber linear body with respect to the core yarn, for example, the holding by the force of sandwiching between the plurality of core yarns (for example, between the plurality of core yarns in a twisted state). Holding by the fixing force of the fixing substance such as adhesion or fusion to one or preferably two or more core threads, or the combined use of both (the force of sandwiching between a plurality of core threads and the fixing force of the fixing substance). (Combined use of holding by) is possible.

In the case of holding the fixing substance by the fixing force, for example, a heat-sealing yarn can be 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, 10 to 300 denier monofilament yarn, spun yarn, and multifilament twisted yarn. The heat-sealed yarn can also be used. Examples of the material of the core yarn include, but are not limited to, polyester fibers, polypropylene fibers, polyethylene fibers, and polyamide fibers.

(1-3) As the fiber-made striatum in the pile for the treatment, for example, single fiber, synthetic fiber, natural fiber staple yarn or the like can be used.

(a) A fiber-made striatum in the pile for the treatment is preferably a single fiber having poor water absorption of 0.03 to 3 denier. The fineness of the single fiber having poor water absorption is more preferably 0.05 to 2 denier, further preferably 0.1 to 1.5 denier, 0.1 or 0.2 to 1.2 denier, 0. It can be 1 or 0.2 to 1 denier, or 0.1 or 0.2 to 0.8 denier.

By making the single fiber as a fibrous striatum in the treatment pile poor in water absorption, it is possible to assume that the treatment pile has an inward water absorption force due to a capillary phenomenon. ..

A large number of single fibers are densely arranged in the circumferential direction so as to form a radial shape in the radial direction about the axis of the pile for processing, and are densely arranged in the axial direction, and the density becomes higher toward the inward. Since the single fiber of No. 1 is a single fiber having poor water absorption of 0.03 to 3 denier, a strong water absorption force acts inward due to the capillary phenomenon, and a relatively large amount of water is rapidly applied inward. Can absorb water.

The outer peripheral portion of the pile for treatment that has absorbed water in this way has a low water content due to the capillary phenomenon, 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 maintain a non-wet state. Therefore, the outer peripheral surface portion in the state of absorbing moisture 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 to this. Further, it is desirable that the length of the single fiber is constant, but the length is not limited to this.

(c) The water absorption rate of the single fiber having poor water absorption can be, for example, 5% or less at 20 ° C. and a relative humidity of 65%. It is preferably 3% or less, more preferably 2% or less, still more preferably 1% or less at a relative humidity of 65% at 20 ° C. Such a single fiber may be made of a filament such as a polyester fiber, a polypropylene fiber, a polyethylene fiber, or a polyamide fiber, and may be a total single fiber or a partial single fiber, if necessary. Can be crimped such as a crimped filament, or the whole or a part of all monofibers or a part of monofibers can be hydrophilized with various surfactants or the like.

(d) The number of single fibers as striatum made of fibers in the treatment pile is, for example, about 10,000 to 250,000 per 1 cm of axial length of the treatment pile (depending on the size of the fineness of the single fibers). The number of fibers can be small and large, respectively. When the single fiber is 0.7 denier, the number of fibers per 1 cm of the axial length of the pile for processing, for example, about 50,000) is approximately 50,000 around the axis. It can be densely arranged so as to form a radial shape in the radial direction and densely arranged in the axial direction.

(e) The single fibers as the striatum made of fibers in the pile for the treatment may be in a state of not being twisted with each other. Since the single fibers are not twisted together, it is difficult to prevent the strong water absorption force from acting inward in the radial direction due to the capillary phenomenon.

(1-4) Of a plurality of areas in which a large number of piles for treatment are arranged on the substrate, any one or more predetermined areas are adjacent to other areas, and piles arranged in the predetermined areas. The piles that make up the group are, on average (or all piles), the area of the cross section of the substantially cylindrical portion, compared to the piles that make up the piles that are arranged in other adjacent areas. Is 40% or more larger, the ratio of the axial length / base diameter is 1/2 (or 3/5) to 4/1, and the bearing capacity in the axial direction is relatively large. When the ratio of axial length / base diameter is 1/2 (or 3/5) to 3/1 (or 14/5), the pile has a relatively large bearing capacity in the axial direction and is applied to the surface of the substrate. On the other hand, it tends to have independence.

(a) A plurality of areas in which a large number of piles for treatment are arranged on the substrate are, for example, those having the same shape and the same area, or a predetermined area and another area are adjacent to each other and alternately arranged in a certain direction (a). These include those that are lined up with the same width or with different widths of the predetermined area and other areas, those in which the predetermined area is surrounded by other areas, those in which the predetermined area surrounds other areas, etc. It is not limited to. One area also includes a large number of processing piles arranged in a row or in a staggered pattern on the substrate, for example in a linear, curved or wavy shape (eg, sinusoidal, triangular wavy, rectangular wavy, saw wavy). Can be configured.

It is not necessary that something other than the pile exists as a delimiter between the plurality of areas, or that something indicating the delimiter is drawn.

A 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. In addition, there may be a plurality of regions consisting of piles having different heights (or other dimensions) in one area.

(b) A predetermined area is adjacent to another area, and the piles constituting the pile group arranged in the predetermined area are averaged as compared with the piles constituting the pile group arranged in the other adjacent areas. Then (or all piles), the cross-sectional area 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. / The base diameter ratio is 1/2 to 4/1.

(c) Among the piles for treatment, those having an axial length / base diameter ratio of 1/2 to 3/1 and having independence to the surface of the substrate stand up against the surface of the substrate. As the axial core line, the axial core line perpendicular to the surface of the substrate is most desirable, but in addition, for example, about 60 to 90 degrees, or 70 degrees or 80 to 90 degrees to the surface of the substrate. The axis line that forms the right angle 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 substantially spherically reduced in diameter toward the end. Examples thereof include a rotating curved surface having a substantially cylindrical shape on the base side and a rotating curved surface having a substantially spherical diameter reduced from the base to the end toward the end.

(d) The piles that make up the pile group in other areas adjacent to the predetermined area have an axial length / base diameter ratio of 1/2 to 5/1 (or 4/1 or 3/1). Can be. When the ratio of the axial length / base diameter is 1/2 (or 3/5) to 3/1 (or 14/5), it tends to be self-supporting to the surface of the substrate.

(e) The axial length of the piles that make up the pile group arranged in the predetermined area is the axial length of the piles that make up the pile group arranged in the other area adjacent to the predetermined area. On average (or all piles) are preferably equal or short, but can also be long.
