How To Determine The Filling Content Of A Quilt

Determining the filling content of a quilt requires combining label information, professional testing, and simple experiments. The key is to carefully read the product label and supplement it with sensory verification.

 

1. Check the Product Label (Most Authoritative) Legitimate quilt labels will clearly indicate the type and percentage of filling material. This is the primary basis for determining the content.

Down Quilts: Look for "Down content ≥ 90%" (e.g., 95% white goose down). Note the difference between "down content" and "down fraction," the latter being the new national standard.

Silk Quilts: Should specify "100% mulberry silk" or a specific proportion (e.g., 70% mulberry silk + 30% tussah silk). Avoid vague descriptions such as simply writing "silk."

Synthetic Fiber Quilts: Should specify the specific percentage of each fiber, such as "55% soybean fiber, 45% polyester fiber." Higher content generally indicates better performance.

 

2. Sampling and Observation Using the Inspection Port: Most comforters have a sampling port where a small amount of filling can be pulled out for preliminary judgment:

Down Comforters: High-quality down comforters have large, fluffy down clusters, a soft feel, and are free of stems. If they contain a large number of small feathers or loose fibers, the down content may be low.

Silk Comforters: Long-fiber silk is continuous and has a uniform luster; short-fiber or mixed with synthetic fibers is prone to breakage and has a dull luster.

Wool Comforters: Fibers are naturally curled and of uniform length; if mixed with short hairs or synthetic fibers, they feel rough and are prone to clumping.

 

3. Rebound and Press Tests (Auxiliary Judgment):

Down Comforters: A rapid rebound within 3 seconds after being pressed indicates good fluffiness, usually corresponding to a high down content and high-quality filling.

Silk Comforters: The rebound is slower but uniform, with no obvious collapse; rapid collapse or uneven rebound may indicate insufficient filling or low content.

Synthetic fiber quilts: They rebound quickly after being pressed, but they tend to clump together with long-term use, affecting their actual warmth retention.
