For coating process, be not particularly limited, can adopt cutter to be coated with the methods such as method, intaglio plate rubbing method, airblade coating method, but from the viewpoint of good dipping, it is comparatively desirable that cutter is coated with method, airblade coating method.
In the utility model, the resinous coat nonwoven after coating is implemented to embossing processing, make its cross section waviness (sinusoidal).Now, or use paper bowl as the pressure roller of the relative side of knurling rolls, or it is passed through having the pressure roller of protuberance and have between the pressure roller of recess chimeric in raised part, press relief pattern, it is good making cross section waviness.Accordingly, can make the apparent thickness of resinous coat nonwoven reach the more than 2 times of actual (real) thickness.
As the shape of embossing, can list the polygon prism shapes such as cylindrical shape, triangular prism shape, quadrangular shape, the polygonal pyramid platform shapes such as truncated conical shape, Rhizoma Sparganii frustum shape, tetragonous cone table shape etc., comparatively desirable with tetragonous cone table shape among these shapes.Size about embossing shape, in the plane of resinous coat nonwoven, on this embossed pattern outline line, arbitrarily the maximum length of point-to-point transmission is good (more preferably 700 μ～1600 μ m at 500 μ m～2000 μ m, more preferably 1000 μ m～1300 μ m), height is desirable (more preferably 300 μ m～650 μ m, more preferably 350 μ m～600 μ m) at 250 μ m～700 μ m.
In addition,, as the arrangement of embossed pattern on resinous coat nonwoven, can list embossed pattern and be arranged in latticed mode, the mode of sawtooth arrangement, the mode of random alignment etc.Ideal embossing mode is that, from the unilateral observation of resinous coat face, the recess of the shape of falling tetragonous cone table is the mode (inverted trapezoidal grid type) that sawtooth is arranged.
Fig. 1 is an example that shows inverted trapezoidal grid type embossing mode.The recess of this inverted trapezoidal grid type has tetragonous cone table shape, wherein, one side of the recess bottom surface of this tetragonous cone table shape is the summary square of 250 about μ m～400 μ m, end face (opening surface of recess) one side be the summary square of 900 μ m～1200 μ m left and right.In addition, the height of tetragonous cone table (degree of depth of recess) be take 350 μ m～600 μ m left and right as good.
In addition,, except adopting the embossed pattern of above-mentioned inverted trapezoidal grid type, can also adopt other various patterns.For example, the shown embossed pattern that the protuberance of cylindrical (coin-shaped) is carried out to sawtooth arrangement in Fig. 3.What in Fig. 4, show is the embossed pattern that the shape (formed is recess) after the protuberance of quadrangular shape is pressed into is arranged regularly, shown in Fig. 5 is though that the protuberance of squamous has a little irregular part, but the embossed pattern of arranging more regularly on the whole.What in Fig. 6, show is the embossed pattern that left and right portion and the central portion of shape after the protuberance of quadrangular shape is pressed into (formed is recess) carries out the crocodile skin shape of different arrangements.What in Fig. 7, show is the embossed pattern after the recess of hexagonal prism shape is arranged regularly, and what in Fig. 8, show is the embossed pattern after criss-cross protuberance is arranged regularly, and in addition, what in Fig. 9, show is the embossed pattern of knitted fabric apperance.
Embossing processing is good by the laggard behavior in ℃ left and right, resinous coat nonwoven heating to 130～180, and now, the line pressure of embossing processing is that 40～100kN/m left and right is for good.
［ resinous coat nonwoven ］
The final mass area ratio of resinous coat nonwoven of the present utility model is 100～250g/ ㎡.Too small undercapacity, excessive against light-weighted object.
Resinous coat nonwoven of the present utility model, its apparent thickness/actual (real) thickness is more than 2.Accordingly, can obtain lightweightly, and there is the nonwoven of good appearance design (embossed pattern is high-visible).Here, the apparent thickness of resinous coat nonwoven refers to, the dial type calibrator (model SM-112) that utilizes TECLOCK company to produce, carries out to the resinous coat nonwoven not bearing a heavy burden the value drawing after practical measurement, is equivalent to the distance between upside thick line and downside thick line in Fig. 2.In addition, actual (real) thickness refers to as shown in Figure 2 the thickness while observing resinous coat nonwoven cross section with SEM, is the thickness of the least part measured.Distance in Fig. 2 between fine rule and downside thick line is actual (real) thickness.
As shown in Figure 2, if cross section is sinusoidal, apparent thickness is more than 2 resinous coat nonwoven with the ratio (apparent thickness/actual (real) thickness) of actual (real) thickness, even if amount of resin is than in the past few, its embossed pattern is still high-visible, not only has good appearance design but also have good light weight.
If apparent thickness/actual (real) thickness is less than 2, embossing thickens, and appearance design is poor, therefore unsatisfactory.Therefore, be to improve the embossing processing of appearance design, be different from the embossing processing while producing nonwoven, using paper bowl as the pressure roller of the relative side of knurling rolls or use the 1st pressure roller and a pair of pressure roller that oppositely pressure roller can be chimeric to be necessary.
