In this invention, a polymer sheet is irradiated with 50% by laser light irradiation.
The present invention relates to a method for forming countless holes with a diameter of 0 μm or less. Conventionally, the method of forming fine holes in polymer seams is to pierce them with a needle like a sword. Alternatively, sublimable or hydrophilic compounds are mixed and these compounds are sublimated or eluted to form pores, or a blowing agent is mixed and the blowing agent is volatilized.
Generally, methods such as forming bubbles are used. However, these methods tend to have large pore diameters, variations in pore diameter, a large number of closed cells, or the presence of residual P1 ('I:'b) or hydrophilic compounds on the surface of the polymer sheet 1. There are drawbacks to the transitional hat,
A fl that combines both moisture permeability and waterproof properties.
There was a drawback that it could not be said to be sufficient for tt. On the other hand, a technique for making holes in rubber and plastics using a laser beam is also known. However, in the past, carbon dioxide gas (wavelength 10.6 μm) in the infrared wavelength region was generally used.
m) is used, and the diameter of the holes obtained by pulse machining is large, several hundred microns, so the hole density is 600//.
The limit is less than cnl, and beyond this point it was impossible to increase the degree of cutting of the polymer sheet itself. In addition, with the rapid thermal decomposition and gasification of the polymer itself, the deterioration of the physical properties of the polymer itself can be avoided, and composites such as G15 fabric made by bonding fabrics In the field, '711 had the disadvantage that even the nylon fabric was perforated (17), which reduced the performance of the 21-meter fabric (by a significant degree). In addition, in the drilling method using a carbon dioxide laser, the oscillation method is a pulse method, so one hole is drilled with one pulse, and it is difficult to drill countless holes in a large area of the sea 1. However, this method has the disadvantage of being significantly inferior in machining speed and acceleration accuracy, and is currently being applied to machining where a very small number of holes are to be drilled in a limited area. In addition, YAG with a wavelength of 1710 for carbon dioxide laser
Although it is theoretically possible to form 1,710 micropores of carbon dioxide laser-processed holes using a 1-noser (in-1~riu-1~ system laser, wavelength 1.06 μm), it is generally Since polymers such as are poor thermal conductors,
Expansion of the pore diameter is unavoidable, and even if the pore diameter can be made smaller than that of a carbon dioxide laser, it is at most 1./2 Is! The inventors have confirmed that only holes with a diameter of 100 7 m or more can be obtained. The inventors of the present application have conducted intensive research to eliminate these drawbacks and efficiently form fine pores, and as a result, they have developed a pigment that has a light absorption rate of 50% or more in the non-infrared region. Fine resin powder mixed with Go 11 or Plastic Sea 1-
1-9, and Y into the polymer sheet 1.
We have now discovered that the object of the present application can be achieved by using the AGI noser. In other words, the pigment i! absorbs light in the non-infrared region. ; Mixing and pulverizing the leek with a synthetic resin that thermally decomposes it at a relatively low temperature.

[7] By dispersing the fine particles in a polymer and irradiating it with a YΔG laser, the pigment No. 5'l 7- is rapidly heated, a synthetic resin is placed in it, and only the thermally decomposable substances are decomposed and gasified, and the cavity is covered with a polymer sheet. This creates an extremely desirable situation in which the polymer seam 1- itself formed inside is not damaged in any way. The absorption rate of non-infrared light that can be used in this application is 50
% or more for colored powdery synthetic resin A'; 1,
Carbon black, graphite, titanium white, i (i'?!
Examples include white sulfur, zinc sulfide, white lead, tin, antimony oxide, phthalocyanine blue, aniline black, al-12-thylene black, etc., and these can be used alone or in combination as desired. If these pigments are simply dispersed as they are in rubber or plastic, the expected effects cannot be obtained. It is necessary to use at least one compound generally called an extender pigment in combination with these pigments. All known extender pigments can be used, but especially carbonic acid 1
1. Inorganic salts or inorganic oxides such as barium sulfate, alumina, silicic anhydride, talc, magnesium carbonate, and gypsum are suitable. These pigments and extender pigments are mixed with a synthetic resin that generates decomposed gas through thermal decomposition by a known method, and then pulverized]
The particle size may be 007zn1 or less. Pigment, extender pigment, and synthetic resin powder were added in advance to 100μI11.
The following particle sizes may be well mixed and used. Also, even if the particle size before being mixed with the polymer is 1.007 zm or more, it may be 100 μm or more because it is lost during the process of crossing with the polymer.
It may be set to be less than m. Of course, 5 to polymer sea 1 is 1 +) 0 7z m or more, and -.
In applications where the presence of pores with a pore size of 100 μm or more is acceptable, it is recommended to use a colored powdery synthetic resin with a particle size that is at least less than the thickness of the polymer sheet.
ITI can do it. Heat M. Synthetic resins that cause decomposition gas and
Polyester resins, polyacryloni 1-helyl resins, epoxy resins, polyurethane resins, etc. are suitable, but the resin is not limited to 1, te as long as it generates thermal decomposition gas. In addition, in the case of polyester resin, polyacrylonyl-1-lyl, and epoxy resin, a curing agent may not be added. As the polymer seam 1, rubber or plastic alone or a mixture formed into seams 1 to 1 may be used,
These sheet-like materials may be used as a composite sheet 1 for laminating fabrics. In short, the colored powdery synthetic resin must have an absorption rate of 50% or more at non-infrared wavelengths 1, and must contain at least 1) one component such as a synthetic resin that generates pyrolysis gas. , and a small amount of extender pigment. It is necessary that the material be in the form of fine particles containing one or more of the following. The laser type used in this application has a non-infrared wavelength region, such as YAG, ruby, glass, etc., and the laser characteristics, that is, the oscillation method, output, and focusing I nonce, are
Although not limited to ν, polymer seams 1-
A swept beam focused on the surface is considered the best method with current equipment. As for the oscillation method, it is preferable to use a continuous oscillation method in conjunction with a switch, but other methods may also be used. The polymer sheet referred to in the present application refers to a rubber or plastic sheet (1 mm or less) that is made into a sheet shape by a known method such as calendering or inflation heating, and the preferred thickness of the sheet is Generally, it has a range of about 1 00 It m, which is called a film. In the present application, the polymer sheet 1- may be processed as it is, but it may also be used by laminating it with nylon cloth or other fabrics. Furthermore, it is desirable to use Polymer Sea 1 to Hakushu without coloring, but if they are colored, the absorption rate of light in the non-infrared wavelength region due to the coloring must be 50% or less. The pore size of the polymer sheets 1 to 1 obtained by the method of the present application is 1 of the particle size of the dispersed colored powder composite (i'7J resin).
The number of fine pores is determined by the number of colored powdery synthetic resin particles, that is, the blending amount. Therefore, in order to obtain a high degree of moisture permeability, it is natural to increase the amount of colored powdery synthetic resin added to the polymer sheet 1-. It is better to set the particle size of the colored powdery synthetic resin to a larger size. On the other hand, when it is desired to increase the water pressure resistance, the particle diameter can be set as small as possible, so that an extremely wide range of moisture permeability and water pressure resistance can be obtained by the method of the present invention. In addition, the polymer sheet 1~ with the microscopic pores of the focal number 1) obtained in this way has less stuffiness and is excellent in waterproofness, so it is suitable for clothing such as raincoats and sports win 1~breakers. It is the material. Examples] Styrene-butadiene-based synthetic Gol, It, 1.502
