Tests
WHAT IS IT?
This test identifies the fibers present in a filling sample (e.g. polyester, lyocell, wool, silk, etc.).
HOW IS IT DONE?
A sample is either examined under magnification, burned, treated with special solutions or chemically separated. Fibers are identified by distinct characteristics evident under magnification, observed during combustion or revealed during chemical separation (each fiber can be dissolved using specific chemicals).
WHAT DO THE NUMBERS MEAN?
Results are generally given as a percentage of the fiber(s) found during testing. It can be a single fiber (#1) or a blend of two or more fibers (#2). Examples: #1: 100% POLYESTER or #2: 35.5% WOOL, 64.5% POLYESTER
WHY DO IT?
This test is used to determine the fiber content of a filling and is generally required for labeling. A label must state the ratio of multiple fibers.
Standards
IDFL tests polyester filling using the major global standards including EN (Europe), ASTM (North America), JIS (Japan), AATCC (North America), IDFL (Global), ISO (Global).
