| Popis: | Presented here are the basic conditions needed to obtain-as a first step to investigate the resin distribution in resin-finished fabrics by using a carbon-14 tracer-a good microautoradiograph in the cross section of resin-finished fabrics and monofilaments with the aid of three kinds of commercially sold photo-sentitive materials.1. The proper RI concentration in the resin solution is from 150 to 375μCi/10cc2. With the contact method used, the exposure time needed is 35-14 days for a process hard dry plate, and 3-1.5 days for X-ray film. With an autoradiographic dry plate used by the stripping method, the exposure time needed is longer than if a process hard dry plate is used by the contact method.3. Adequate conditions for developing are 15 minutes at 20°C if a Fuji Microfine developer for process hard plates is used; 4 minutes at 20°C if a Rendol developer for X-ray film is used and 7 minutes where an autoradiographic dry plate is used. |
