Textiles – Quantitative Chemical Analysis – Part 23.
Mixtures of Polyethylene and Polypropylene (Method
Using Cyclohexanone)
1 Scope
This Part of GB/T 2910 specifies method using cyclohexanone to determine, after
removing the non-fibrous substances, the content of polyethylene fiber.
This Part is only applicable to the mixtures of polyethylene and polypropylene blend
fiber.

GB/T 2910.1 Textiles - Quantitative Chemical Analysis - Part 1. 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.
