In addition, the outdoor clothing fabric has high ultraviolet resistance, and most of the existing fabrics cannot have the performances of sweat absorption, moisture removal and ultraviolet resistance.
The sweat absorption and moisture removal performance of the fabric mainly depends on the fiber structure of the fabric. The fiber on the market at present obtains the performance of moisture absorption and quick drying mainly through three ways, firstly, a hollow micro-porous structure is formed, the fiber is in a hollow fiber shape, and the side surface of the fiber is provided with micro-pores communicated with the hollow part; the micro-pores can absorb sweat into the hollow part for storage, or the sweat stored in the hollow part is evaporated by body temperature and then is discharged out of the fabric through the micro-pores; the sweat absorption speed of the fiber fabric is 1.3 times of that of cotton fabric, and is far better than that of common polyester fabric; secondly, silk fibroin with high moisture absorption property is coated on the water-absorbing fiber, so that better moisture absorption performance is obtained; thirdly, using special spinning process, making the inner and outer tube walls of the fiber have long and thin grooves and forming hole distribution similar to neural network shape, sweat can enter the grooves of the fiber rapidly and evaporate rapidly through the grooves and holes to make human body have dry, cool and comfortable feeling.
Compared with the conventional fiber fabric, the porous ultrahigh molecular weight polyethylene/composite fabric prepared by the invention has a complex structure and a simple preparation method, is a product with high technical content and high added value, and has a good market prospect. Meanwhile, the sweat-absorbing and moisture-removing outdoor ultraviolet-proof fabric has dual functions of moisture absorption and sweat removal and ultraviolet resistance, and can increase the wearing comfort of a human body while reducing or avoiding the damage of ultraviolet rays in sunlight to the human body.
