[0002] The working principle of a conventional outdoor woven fabric outdoor workwear is mainly to form a microclimate layer between the human body and the workwear by filling materials such as flake and down, so as to reduce the rapid loss of heat in the human body to achieve the purpose of keeping warm. The disadvantage of this design is that the overall warmth-keeping performance of the workwear mainly depends on the thickness and area density of the warmth-keeping flake, and the outer fabric and the lining of the workwear almost have no contribution to the warmth-keeping performance of the workwear. Generally speaking, the thicker the flake is, the greater the area density is, and the better the overall warmth-keeping effect of the workwear is. Therefore, the way to improve the warmth-keeping performance of the workwear is too single, the workwear becomes very heavy and thick when it is used in a cold environment, and it is extremely inconvenient to wear. Meanwhile, the outer fabric of this kind of workwear almost adopts flammable fibers, and the lining and the flake are also flammable fibers, so that the fabric of the workwear does not have the flame-retardant property, and the functionality is too single, which does not meet the current trend of the protective fabric having the flame-retardant function.

[0008] Further, the yarns of the satin surface layer are 11.81tex x 2, 50 S / 2 yarns.

[0009] Further, the yarns of the satin surface layer are spun from light heat-accumulating fibers and flame-retardant fibers.
