What is the resilience and fluffiness of polyester comforters?

What is resilience and fluffiness
Resilience refers to the ability of the quilt core to return to its original shape after being compressed. It reflects the elasticity of the fibers inside the quilt, which directly affects the service life and comfort. If the resilience is poor, the quilt is easy to collapse and become thinner, and the warmth retention will also decrease.
Fluffiness refers to the degree of expansion of the quilt filling in a unit volume. Quilts with high fluffiness tend to contain more air layers, which help to keep warm and breathable.
Although these two indicators are different, they are interrelated in actual use: fluffiness determines the volume and touch of the quilt, and rebound determines whether the quilt can continue to maintain this fluffiness.

Analysis of the rebound characteristics of polyester fiber
Polyester is a synthetic fiber with high elastic recovery performance. After compression and stretching, it can quickly return to its original shape and is not easy to deform. This makes the quilt made of polyester have a certain resilience in daily use and can resist the collapse problem caused by daily compression.
In particular, hollow polyester or three-dimensional curled polyester fibers, due to the special fiber cross-sectional structure, can retain more air and deformation space, thus improving the rebound effect. Even after a long period of use, this type of fiber is not easy to collapse, thus extending the service life of the quilt.
But at the same time, it should be noted that the process level of polyester fillings from different manufacturers is different, and compression density, fiber thickness and spinning process will affect the rebound performance. If you choose inferior filling materials, you may lose elasticity in a short period of time.

Fluffy performance and actual experience
The fluffiness of polyester comforters is affected by many factors, among which fiber structure, filling amount and sewing process are the main ones.
Under normal conditions, the hollow structure of polyester fibers is conducive to the formation of a bulky layer, so newly purchased polyester comforters often appear full and fluffy. At the same time, its lightweight properties also make the quilt less likely to press the body during use, improving the overall comfort.
From the user experience, a polyester comforter with appropriate fluffiness can provide a stable insulation layer and is not prone to cold spots. Especially when used in winter, this fluffy state helps to maintain the constant temperature of the quilt.
Excessive fluff does not necessarily mean comfort. Some quilts with too thick filling may affect breathability. Therefore, the fluffiness should match the seasonal needs. Summer quilts should be light and breathable, while winter quilts can be appropriately thickened to enhance thermal insulation.

External factors affecting rebound and fluffiness
Although polyester itself has a certain elasticity and fluffy structure, its performance will also be affected if it lacks reasonable maintenance in actual use:
* Cleaning method: High-temperature washing, strong spin drying or frequent washing will destroy the curling structure of polyester fibers and cause elasticity to decrease.
* Use environment: Long-term pressure, moisture or direct sunlight will cause the fiber to age and collapse, thereby losing fluffiness.
* Storage method: If the quilt is compressed and stored for a long time in the non-use season, it may take some time to restore the fluffy state after leaving the warehouse.
It is recommended to dry the polyester comforter regularly and avoid pressing it under heavy objects for a long time to delay performance degradation.

How to choose a fluffy and elastic polyester comforter
When buying a polyester comforter, you can judge its resilience and fluffiness from the following aspects:
*Press test: Press the quilt lightly with your hand and then release it. If it quickly returns to its original shape, it indicates that it has good rebound performance;
*Fluffy observation: judge its fullness and softness by sight and touch;
*Check the filling material: three-dimensional hollow and curly polyester usually have better fluffiness and rebound performance;
*Reference weight and number of layers: The appropriate weight can ensure warmth while maintaining a comfortable fluffiness.
