Definitions

  • a flexible thermoplastic plastic sheet including a plastic film is provided with a large number of fine holes to impart air permeability.
  • Such perforated plastic sheets usually have the slimy and sticky feel typical of plastic sheets and, depending on the application of the sheet, their luster. The skin is remarkably disliked.
  • techniques such as embossing to eliminate the glossiness of the sheet surface and providing irregularities and apertures on the surface, as well as glossy sheet materials
  • a third component having an erasing effect and an opening forming effect is mixed in advance, and the gloss and opening are performed at the sheet-production stage.
  • first-direction ribs whose both sides bend downward along the I direction, and both sides downward along the second direction.
  • bent second direction ribs intersect.
  • FIG. 7 and 8 are plan views showing a plastic sheet according to another embodiment of the present invention.
  • Fig. 1 the minimum unit of the structure consisting of ribs for sheet 1 is shown by a solid line, and this unit is repeated in each of the vertical and horizontal directions as shown by a chain line to constitute the entire sheet 1.
  • Sheet 1 is composed of first direction ribs ⁇ ⁇ ,, Y 2 along the first direction Y and second direction ribs X ′′ X 2 along the second direction X.
  • the width of each rib is almost the same.
  • Each rib bends down on both sides of sheet 1 with ribs Y 2 having lower edges 2, 3 and ribs X 2 having lower edges 4, 5, respectively.
  • Two adjacent first directional ribs ⁇ 2 , and two adjacent second directional ribs,,, ⁇ 2 intersect at intersections C 1, C 2, and C 4 .
  • Figure 3 rib gamma, and m-m line cross-section of, m rib x 2 - is a schematic cross-sectional view of the 'm' shear plane.
  • the rib has an arc with a substantially semicircular cross section, a top ⁇ 2 or ⁇ , and a substantially uniform thickness t, and a rib Y,
  • sheet 1 For the appearance of sheet 1 is woven appearance similar to woven fabric, the width d !, d 2 of Li Bed 0 ⁇ . 01 to 3 mm, more preferably between 0.05 to 2 mm, the gap 6 The number should be 5 to 90, more preferably 10 to 60 per 25.4 mm length.
  • Sheet 1 is made of polyethylene or polypropylene Ren, the port re-esters and other thermoplastic plastic steel click sheet, basis weight 5 ⁇ 50gZm 2, a more preferred properly as possible de be used in 20 ⁇ 30gZm 2.
  • the rib surface should be made uneven to reflect light irregularly, and the outline of the void 6 should be irregular. Bend lines, change rib width irregularly along its length, change rib pitch appropriately, color sheet 1 in appropriate color This is effective.
  • FIG. 7 is a plan view showing another embodiment according to the present invention.
  • Li Bed Y have Y 2 and X physician chi 2 Prefecture
  • Li blanking width d have d 2 is substantially equal
  • the pitch P have P 2 also are substantially equal.
  • FIG. 8 is a plan view showing still another embodiment.

  • the plastic sheet 1 has a belt-like bridge 15 connecting the ribs 1 and 2 .
  • the IX-IX line and XI-line cross section are shown in Figs.
  • Crosslinked 15 extends between opposite lower edge 3, 2 of the ribs and Upsilon 2, having a width W and a thickness t '.
  • the width W may vary irregularly between the two ends of the bridge 15, and the thickness t 'is substantially the same as the rib thickness t so as not to impair the flexibility of the sheet 1. Or smaller.
  • the bridge 15 need not be provided in every void 6 of the sheet 1. In this sheet 1, the cross-links 15 and the ribs in the vicinity thereof can create a woven appearance corresponding to a twill structure.
  • FIG. 12 is a plan view showing still another embodiment.

  • the second ribs (Xh X 2, X -) is the pitch P 2, P 4 is alternately repeated.
  • Plastic sheet 1 can be made by various manufacturing methods.
  • One of the simple manufacturing methods is to place a heat-softened raw plastic sheet on the upper side of a wire mesh where the wire forms a plain weave, twill weave, satin weave, etc., and vacuum from the bottom of the wire mesh.
  • the raw sheet is adapted to the structure of the wire mesh and shaped, and the mesh sheet is sucked and ruptured at the mesh portion to form openings.
  • a wire mesh is stretched around the outer periphery of the rotating drum, and suction is applied to the rotating drum in a predetermined area. If the heated and softened raw sheet is continuously supplied to this drum, plastic sheet 1 is continued. Can be produced on a regular basis.
  • sheet 1 shown in Fig. 8 can be obtained by expanding sheet I in Fig. 1.
  • the sheet 1 manufactured by such a method often has an irregular shape of each part, and such a sheet 1 is also included in the present invention.
  • fine irregularities can be obtained on the surface of the rib formed by shaping the wire.
  • the surface appearance of the sheet can be made similar to that of woven fabric, such as plain weave or twill weave.
