The basic material of coral fleece is polyester fiber, which is different from the material of plant fiber or viscose fiber. It will not shrink at room temperature, but will expand when it meets water, and will return to its original state after drying. As long as the temperature does not exceed 120. It is best to control the washing within 80. Coral velvet has good physical properties and high warmth retention. Wool tips curl easily and turn coral after 2-3 years of use. The disadvantage is that it is easy to "harden". If the coral wool you buy is unprofessional and there are many cases of cheap supply, that is another matter.

Coral velvet is just a symbol of the times of polyester fabrics. The development history of polyester fiber can be traced back to 60 years ago, and the initial symbol of the times is Raschel;

The fabric was upgraded around 1998, and the symbol of the times was "polar fleece";

In 2002, it was upgraded again, and the symbol of the times was "coral velvet";

The upgrade logo around 2006 is "flannel";

The upgrade logo around 2008 is "Fu Guirong"

The ultimate upgrade sign around 20 13 is "warm cotton wool" integrated with antistatic fiber yarns and other technologies, and wool has also been improved in many versions. In fact, the symbol naming of each era has certain significance and is also the presentation of creativity. The quality of a product is by no means compared with parameters such as wool length, wool short, thickness, weight and price. For comfort, skin-friendliness, durability, antistatic, non-caking, warmth retention, air permeability and other parameters to make reference. I hope this reply can solve your confusion and reward you when the above answers are useful to you.
