Mbth: polar fleece, also known as cashmere) is a polyester knitted fabric made of grey cloth woven by large circular loom, and then processed by various complicated processes such as dyeing, napping, combing, shearing and shaking. The fabric is soft to the touch, with the characteristics of high fluffy density, good elasticity and not easy to shed and pilling. It can be divided into striped cashmere, embossed cashmere and jacquard cashmere.

Development of polar fleece: In the early 1990s, polar fleece was first produced in Taiwan Province Province, China. Grey cloth is woven by circular knitting machine, dyed at high temperature and high pressure, and then finished (such as carding, shearing, shaking table and setting).

In the mid-1990s, Quanzhou, Fujian Province also began to produce polar fleece, which is generally produced in Taiwan Province Province. The price was relatively high at that time. Later, Zhejiang, Jiangsu Changshu, Wuxi, Changzhou and other places also produced polar fleece. Looking at the domestic production level of polar fleece, the quality of polar fleece in Jiangsu is better, and the price of polar fleece in Zhejiang is better.

The difference between polar fleece and ordinary fabric: the fabric has been specially treated, such as adding antistatic additives, flame retardant additives, infrared additives and so on. For some special polar fleece, for example, antistatic fiber is added to the fabric when weaving, but the polar fleece added with this fiber is still not much in the domestic market.

Polar fleece can also be compounded with all fabrics for better cold protection. For example: polar fleece and polar fleece, polar fleece and cowboy, polar fleece and lamb, polar fleece and mesh fabric with waterproof and breathable film in the middle, etc.
