粒子を析出させる方法、いわゆる析出粒子方法がある。One method for obtaining a film with such surface roughness is to apply a phosphorus compound or the like to a metal compound dissolved in the reaction system during the production of polyethylene naphthalate, for example, a metal compound dissolved in the yarn after the transesterification reaction. There is a so-called precipitated particle method, in which fine particles are precipitated.

In other words, the additive particle method is a method in which inert fine particles are blended into polyester either in the polyester manufacturing process or in the extrusion process before film formation.These inert fine particles include, for example, kaolin, Merck, magnesium carbonate, etc. , calcium carbonate, barium carbonate, calcium sulfate, barium sulfate, lithium phosphate, calcium phosphate, magnesium phosphate, aluminum oxide, silicon oxide, titanium oxide, lithium fluoride, etc., and Ca, Ba, Zn, Mn.
