Polyester Fills Testing
Polyester Fills Testing and Quality Assurance
The form for submitting polyester fills samples can be found here.
IDFL performs many synthetic fill quality assurance services including testing bulk filling material and finished products, collecting samples from factories or retail stores and inspecting finished products. Services can be performed same-day for an additional fee.
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.
IDFL tests polyester filling using the major global standards including EN (Europe), ASTM (North America), JIS (Japan), AATCC (North America), IDFL (Global), ISO (Global).
