Down is long in the goose, duck's abdomen, into a reed-like down, into a piece called feathers. As down is an animal protein fiber, than cotton (plant cellulose) insulation, and down spherical fibers densely covered with millions of triangular-shaped tiny pores, with the temperature change and contraction expansion, produce temperature regulation function, can absorb the body to emit the flow of heat, isolated from the invasion of cold air.

What is a down alternative comforter?

The main difference between a down comforter and an alternative down comforter is the filling inside. As the name implies, down alternative comforter is filled with materials such as cotton, polyester fiber, silk, etc. I will give you a detailed description of the types of down alternative comforters below.

Polyester fiber

Polyester fiber

Polyester fiber is a synthetic fiber obtained by spinning polyester condensed from organic dibasic acid and diol, and it is a low-cost artificial chemical fiber synthesized from derivatives produced by oil and natural gas production. Polyester quilts are a more common and cheap alternative to down quilts.


1) It has high strength and elasticity. So it is strong and durable, wrinkle and iron-free.

2)If there is enough air in a certain insulation layer, there will be more and more insulation. According to this simple principle, chemical fibers are hollow, and experiments show that this shape does insulate more than ordinary fibers.

3) Polyester fabric has better light resistance than acrylic, and its light resistance is better than natural fiber fabric. Especially, the sunlight resistance behind glass is very good, almost equal to acrylic. In addition, the initial modulus of polyester is high, so the fabric is stiff and has good dimensional stability.


1)The disadvantage of polyester quilt is that polyester fiber structure is dense, high crystallinity, internal macromolecules do not have hydrophilic genes, so the moisture absorption is low, not easy to dye, breathability and sweat absorption is poor, and also for strong alkali resistance is poor.

2) In the winter time when the weather is dry and dryer, polyester quilts are easy to generate static electricity after friction.

Silk quilts are the more expensive of the down alternative quilts (similar in price to a down comforter). However, silk comforter is also the healthiest of all comforter types. People with cardiovascular disease or allergies should give priority to silk comforters. You can learn about the top 7 health benefits of silk comforters.


1) Super soft comforter. The silk quilt is fluffy and soft, so it is covered with a large force area and a small pressure, so it feels very light and does not have the feeling of being pressed by the cotton quilt, so that the cardiovascular is not burdened.

2) Moisture absorption and breathability. Because the silk quilt contains "hydrophilic side chain amino acids", it can absorb moisture inside the quilt and exclude it, so that the quilt is dry and pleasant.

3) It's not easy to be allergic. The silk quilt is made of silk protein, which is a natural material and is very skin-friendly, so it is not easy to produce allergies and other problems.

4) Anti-mite and anti-bacterial. Ordinary quilts are susceptible to mold and mildew when exposed to moisture, as well as mites and bacteria invasion. And silk is covered with a layer of silk gel outside, which has natural immunity to mites and many kinds of microorganisms. It is great for people who are allergic to mites.

5) No static electricity. The winter weather is dry, polyester fiber is easy to generate static electricity, adsorbing dander and a lot of dust . While silk is a protein fiber, friction will not generate static electricity.


1) High price. The price of silk comforters is similar to down comforters. If the content is 100% silk comforter, it may be more stressful for many friends to bear.

2) Quality varies. Many people do not know enough about silk quilts, it is easy to buy counterfeit products. You can tell good or bad silk quilt by 3 steps.
