Abstract

The invention relates to an antibacterial polyamide yarn and a preparation method thereof.The preparation method comprises the steps that polypropylene fibers, an antioxidant, nano titanium dioxide, a silver ion-loaded antibacterial agent and silicon carbide are evenly mixed and heated to be melted, and a first melt is obtained; pretreating the chinlon slices with a copper ion solution, and heating and melting to obtain a second molten mass; mixing the first melt with the second melt, adding a lubricant, uniformly mixing, and extruding by a screw extruder to obtain a spinning melt; sequentially carrying out blended spinning, drafting and heat setting to obtain the antibacterial nylon yarn. The polyamide yarn prepared according to the preparation method has good antibacterial performance and high mechanical strength, the preparation method is simple and convenient, and the polyamide yarn has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of nylon production, in particular to an antibacterial nylon yarn and a preparation method thereof. Background technique [0002] Nylon, scientific name polyamide fiber, commonly known as nylon (Nylon), English name Polyamide (referred to as PA), nylon is the trade name of polyamide fiber, is the general term for thermoplastic resins containing repeated amide groups (-NHCO-) ​​on the main molecular chain. The main varieties are nylon 6 and nylon 66. Nylon yarn is a fiber made of polyamide, divided into nylon filament and nylon staple. [0003] Nylon has a wide range of applications. For example, in clothing, nylon filaments are made into elastic yarns, and short yarns are blended with cotton and acrylic fibers. Nylon can be used to make sportswear, casual clothing, quick-drying clothes, down jackets, outdoor tents, etc. The main industrial application of nylon filament is to make high-performance tires an...
