<p><P>PROBLEM TO BE SOLVED: To provide a method for discriminating a cellulose foreign body that is mixed inside or attached on the surface of a molding material resin and a molded resin. <P>SOLUTION: The method for discriminating a cellulose foreign body and a cellulose substance includes a step of measuring infrared microscopic spectrum of the cellulose foreign body that is mixed inside or attached on the surface of the molding material resin or molded resin, and the cellulose substance present in the surrounding environment of the molding process of the molded resin by transmission measurement or reflection measurement, and a step of comparing a value obtained by dividing the absorbance of a peak having the strongest absorbance appearing in the range of wave number 1400-1350 cm<SP>-1</SP>of the spectrum by the absorbance of a peak having the strongest absorbance appearing in the range of wave number 3000-2800 cm<SP>-1</SP>of the spectrum, the wave number of the peak having the strongest absorbance appearing in the range of 1460-1400 cm<SP>-1</SP>and the wave number of the peak having the strongest absorbance appearing in the range of 1180-1140 cm<SP>-1</SP>. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
