Problems solved by technology

The wear resistance of polypropylene fiber is second only to that of polyamide fiber; it has good corrosion resistance, especially for inorganic acid and alkali stability; it does not mold, rot, and is not afraid of moths; but polypropylene fiber does not absorb water and is very static Large, room temperature volume resistivity up to 10 17 The disadvantage of Ω.cm, because it is not hygroscopic, airtight, uncomfortable, poor thermal stability, and easy to absorb dust, it is not suitable for clothing

Abstract

The invention provides a preparation method of antistatic polypropylene fiber. The preparation method comprises the following steps of: adding tetrapod-shaped zinc oxide whiskers (ZnO), conductive potassium titanate whiskers (PTW), conductive titanium pigment and the like into isotactic polypropylene powder; and then directly extruding and spinning to form the antistatic polypropylene fiber with high strength in a co-rotating twin-screw fusing and mulling extruder. The antistatic fiber can be widely used in workplaces prohibiting static electricity, sparks, dust and the like. The prepared polypropylene profiled fiber can be used for sports and leisure apparel for quick moisture absorption and wicking.

Description

Technical field [0001] The invention relates to a method for manufacturing antistatic polypropylene fibers, including zinc oxide whiskers (ZnO), conductive potassium titanate whiskers (PTW), polypropylene material modification and other fiber manufacturing methods, belonging to fiber material manufacturing technology . Background technique [0002] Polypropylene fiber, also known as PP fiber or polypropylene fiber, is a fiber made of isotactic polypropylene melt spun. Its biggest advantage is light weight, and its density is 0.91 / cm. 3 , 20-30% lighter than general chemical fiber, is the smallest specific gravity of all textile fibers; high strength, large elongation, high initial modulus, and excellent elasticity. The abrasion resistance of polypropylene fiber is second only to polyamide fiber; it has good corrosion resistance, especially good stability to inorganic acids and alkalis; it is not moldy, does not rot, and is not afraid of moths; but polypropylene fiber does not abs...
