Abstract

The invention discloses a method for preparing antibacterial and antistatic spandex. By compounding nano-carbon black with a specific DBP value and a single-layer graphene oxide in a specific ratio, the graphene oxide is reduced in a heated alkaline environment and forms a stable composite. structure, and then mixed with spandex spinning solution to obtain spandex with antibacterial and antistatic properties. With the addition of only a small amount of graphene and a small amount of carbon black, the invention can make the traditional spandex exhibit excellent antistatic and antibacterial effects, and the product has good spinnability, stable performance, low cost, low industrialization difficulty, and significant practical value. .

Description

technical field [0001] The invention belongs to the field of chemical fiber fabrics, in particular to a preparation method of antibacterial and antistatic spandex. Background technique [0002] Polyurethane Fiber, referred to as PU fiber, is a fiber made of block copolymers containing at least 85% polyurethane chain segments. The American name is Spandex, and Western Europe is happy to call it Elastane Fiber, the trade name of our country is spandex. Because spandex has the characteristics of good elasticity, fineness, high strength, high elongation, light specific gravity, soft hand feeling, good light resistance, excellent dyeing performance and color fastness, it is widely used in underwear and outerwear, women's clothing (swimwear) , tights, pantyhose, etc.), and industrial, biomedical fields. [0003] Once upon a time, as the "noble" fiber in the chemical fiber family, spandex was very expensive, prohibitively expensive, and felt unattainable. Nowadays, with the rapi...
