General Principles of Testing (GB/T 2910.1-2009, ISO 1833-1.2006, IDT)

3 Principles

Use cyclohexanone to dissolve and remove the polypropylene fiber from the mixture with the known dry mass. Collect the residues, clean, dry and weigh; use the modified mass to calculate its mass percentage in the dry mass of mixture. The mass fraction of polypropylene fiber can be obtained from the difference above.

4 Reagents

Use the reagents specified in GB/T 2910.1 and this Part. 4.1 Cyclohexanone. boiling point of 156°C. ......
