Abstract

The invention discloses an antibacterial and antistatic sportswear fabric and a preparation method thereof. By selecting carbon black with a specific DBP value and compounding it with single-layer modified graphene in a specific ratio, a nanocomposite structure is formed, which has good conductivity. . After in-situ copolymerization with terephthalic acid and ethylene glycol, special-shaped spinneret spinning, and warp and weft weaving, a fabric with antibacterial, antistatic, moisture absorption and perspiration functions can be obtained, which can be used in sportswear. The present invention endows traditional polyester fibers with properties such as anti-static, anti-ultraviolet, and antibacterial properties by only adding a small amount of graphene and a small amount of carbon black. At the same time, the special-shaped cross-section improves the moisture-absorbing and sweat-conducting functions of the fibers, which can meet the needs of different applications, and the product can be Good spinnability, stable performance, low cost, little difficulty in industrialization, and significant practical value.

Description

technical field [0001] The invention belongs to the field of fibers, and in particular relates to an antibacterial and antistatic sportswear fabric and a preparation method thereof. Background technique [0002] Polyester is one of the three major synthetic fibers, and is widely used in clothing, packaging materials, daily chemicals, special fibers and even military materials due to its excellent physical and chemical properties. Compared with chemical fiber materials such as nylon and acrylic, polyester has significant cost advantages and cost-effectiveness, so it is the most widely used and has great market demand. However, because polyester itself is a hydrophobic material, it has poor moisture absorption and perspiration after being made into clothing, and is less comfortable than natural fibers such as cotton, linen, silk, etc., and static electricity is easy to accumulate. How to further improve the performance of polyester has become a common problem for manufacturers...
