。[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a polytetrafluoroethylene porous sheet, ie, PT, produced by molding powder method.
The aim is to improve the dyeing method for FE porous sheets.
〈従来の技術〉
ＰＴＦＥを多孔質シートにする方法には、ファインパウ
ダー法とモールデンジパウダー法とがある。<Prior Art> There are two methods for forming a porous sheet from PTFE: a fine powder method and a molding powder method.
ファインパウダー法によって得られた多孔質シートは、
０．１−０．５μの微細な孔よりなり、開孔率は８０〜
９０％であって、外観は普通のソリッドのＰＴ Ｆ−Ｅ
と変わらず、折曲げると、皺が発生する。The porous sheet obtained by the fine powder method is
Consists of fine pores of 0.1-0.5μ, porosity is 80~
90%, appearance is normal solid PTFE
Just like that, when you bend it, wrinkles will appear.
このシートは孔が微細であるため、通常の方法では、染
色出来ないと言う問題点がある。This sheet has a problem in that it cannot be dyed using normal methods because the pores are so small.

で退色すると言う問題点がある。The porous sheet obtained by molding powder method has a bubble (pore) size of 300μ or less and a porosity of 5.
~60%, no wrinkles occur even when folded, and it has the feel of an elastic body. When this sheet is dyed (colored), its strength and elongation decrease by 10% or more, and when it is colored with a vivid coloring agent (organic pigment), the PTFE is fired (300-400℃).
There is a problem with the color fading.
〈発明が解決しようとする課題〉
以上のようなことから、ＰＴＦＥ多孔質シートに対して
、染色が容易で、染色によって強度及び伸びが低下せず

することよりなるものである。An object of the present invention is to provide a method for dyeing a porous PTFE sheet that solves the above-mentioned problems. The dyeing method is to dye a porous sheet with relatively large bubbles obtained by molding powder method.
It is dyed by using a combination of an oil dye or a disperse dye, a nonionic type fluorinated alkyl ester, and an alkyd resin.
