  [1] Embodiment of the present invention

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

The drawings all relate to a water-absorbing pile mat as an example of an embodiment of a pile mat according to the present invention.

  (1) The water-absorbing pile mat A includes a water-absorbing base fabric S (substrate) and a number of substantially cylindrical piles P (mole-like thread bodies). The multiple piles P are arranged on the base fabric S in a state where the lower end portion is coupled to the base fabric S.

  (2) A large number of piles P in this water-absorbing pile mat A are strong twists (500 T) using a monofilament F of 1 denier polyester fiber as a decorative yarn and two monofilament yarns of 50 denier polyester fiber as core yarns. / M) 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. 3) 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, and a tensile force is applied to the folded portion, which is the tip of the protruded strong twist molding yarn M, so that the tension of the strong twist molding yarn M protruding in a folded manner After maintaining the above, by releasing the tensile force, the strongly twisted mole yarn M is twisted by itself to form one pile-like mole-like yarn body. By heat-treating this, the twisted strong yarn M that has been twisted is twisted more strongly and has a substantially cylindrical shape centered on the core yarn C, and the tip portion Pa of the pile P is the tip of the radial single fiber F. A large number of piles P having a substantially convex curved surface shape can be formed by the portion.

  (3) As shown in FIG. 4, the cross-sectional shape of the single fiber F as a decorative yarn is a substantially elliptical outer peripheral portion having a ratio of the short axis to the long axis of about 2: 5, and the base is half of the short axis. The shape is a flat multi-leaf shape having substantially triangular leaf-like protrusions Fa having a height of about one third of the minor axis. As an example of the cross-sectional shape of a single fiber as another decorative yarn, as shown in FIG. 5, a shape in which a substantially triangular constant protrusion is formed on a circular outer periphery at equal intervals in the circumferential direction, FIG. As shown in the drawing, a shape in which a substantially rectangular constant protrusion is formed at regular intervals in the circumferential direction on the circular outer peripheral portion can be exemplified, but the present invention is not limited thereto.

  (4) Each pile P in which the base portion is bonded to the base fabric S has a substantially cylindrical shape from the base portion to the tip end portion (not necessarily standing upright as shown in FIG. A single fiber F (which consists of a large number of 1-denier filaments of polyester fibers) by a core yarn C consisting of monofilament yarns of hydrophobic fibers (fibers with poor water absorption) along the axis. Hydrophobic fibers (fibers with poor water absorption) having a water absorption rate of 5% or less at 20 ° C. and a relative humidity of 65%, the same shall apply hereinafter) are densely arranged so as to radiate substantially radially about the axis of the pile P. In addition, it is held in a state of being densely provided in the axial direction, and the substantially cylindrical outer peripheral surface of the pile P is formed by the tip portion of the single fiber F. In addition, the length of the single fiber F as a decoration thread is about 6 mm.

  (5) When this water-absorbing pile mat A is continuously used, or when washing or other washing or cleaning by a household washing machine is repeated, 1 as a decorative yarn from the pile P (mole-like thread) The denier monofilament is effectively prevented from detaching.

  (6) The tip portion Pa of the pile P is formed by a large number of single fibers F of 1-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 convex curved surface is formed by the tips of the single fibers F.

  (7) The core yarn C along the axis of the pile P has 2 monofilament yarns of 50 denier polyester fibers (hydrophobic fibers having a water absorption of 5% or less at 20 ° C. and 65% relative humidity, the same applies hereinafter). They are twisted together.

  (8) At the tip end Pa of the pile P, the density of the ultrafine hydrophobic single fiber F is three-dimensionally inward (for example, if it is an upwardly convex substantially hemisphere, the center of the bottom of the substantially hemisphere). As a result, the water absorption is increased due to the capillary phenomenon, and the density of the ultrafine hydrophobic single fiber F is increased radially inward in the substantially cylindrical portion other than the tip portion Pa, resulting in a strong water absorption due to the capillary phenomenon. Works. 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.

  Further, each pile P has a core yarn C made of a monofilament yarn of hydrophobic fibers along the axis thereof. Therefore, in each pile P, the pile P was absorbed inward of the tip portion Pa and radially inward by capillary action. Moisture is efficiently guided along the core yarn C to the base fabric S having water absorption.

  Therefore, moisture absorbed in the inner end of each pile P or in the inner radial direction of each pile P is prevented from staying in the central portion in the radial direction of the pile P, and the distal end Pa of the pile P is prevented. Hinder further water absorption from the substantially convex curved outer peripheral portion of the pile P to the inner side of the pile P or radially inward from the substantially cylindrical outer peripheral surface portion of the pile P, or the substantially convex curved outer peripheral portion of the pile P or the pile. It is possible to prevent the sticky feeling from occurring on the substantially cylindrical outer peripheral surface portion of P.

  (9) Note that FIGS. 1 to 6 are schematic diagrams for explanation, and do not show actual objects.

  (10) Test example

  The water absorbing pile mat A (pile mat of length 450 mm, width 600 mm, pile P length of the above example) except that the single fiber as the decorative yarn is a 1 denier polyester fiber having a substantially circular cross section. Is about 22 mm, the number of piles P is about 3000, and the number of single fibers F per pile P is about 90,000). When the suspension drying was repeated 10 times), the hair removal rate of the single fiber as the decorative yarn was 0.075% in the comparative water-absorbing pile mat, and 0.051% or 30% or more in the water-absorbing pile mat A The number of single fibers F that were improved and depilated was reduced by about 120,000.
