1. Development history
From the perspective of development history, velvet first appeared in the Ming Dynasty. It is one of our traditional fabrics, so it is relatively backward. The history of flannel fabric is relatively new and can keep up with the trend of the times.
2. Thermal insulation
The raw material of flannel is wool fiber. In the production process, part of the wool is dyed first, and then mixed with part of the primary-color wool, which is blended and spun into blended wool yarn, and finally woven into fabric, which is made by shrinking and roughening. The velvet fabric is fine, long and fine cotton with good maturity, so it is not as warm as wool fiber.
3. Practicality
The price of velvet is lower than that of flannel, so the cost performance ratio is higher. However, in the process of actual use, we will find that the velvet color and hair fall off, which affects the feeling of use. As a new type of environmental protection product, flannel will not lose hair and color during use, so it is highly praised by consumers.
