Natural Fills Testing

Natural Fill Testing and Quality Assurance

The form for submitting natural fill samples can be found here.

Services

IDFL performs many natural 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.

Composition Analysis

What Is It?

Composition analysis identifies the components of a natural material.

How Is The Test Performed?

A specific weight of material is hand separated into component categories.

The test has two parts:

  • The first separation classifies larger components into the following categories fibers and residue.
  • The second separation classifies smaller components from a sub-specimen of animal or plant fibers category.

What Do The Results Mean?

The content analysis report gives the percentages by weight of each component category.

Why Do It?

Governments and buyers require labeling of finished products. The component percentages are the basis of the product label. The various systems for labeling help consumers and manufacturers buy and sell different quality products in a fair and level marketplace.

Fiber Identification

What Is It?

This test identifies the fibers present in a filling sample

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).

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).
