Abstract

The invention discloses a polyamide-6 filament production technology. The Polyamide-6 filament production technology comprises the steps of preparation and drying of raw materials, preparation of POY yarns, preparation of DTY yarns and preparation of polyamide-6 filaments. As a modified antibacterial uvioresistant functional master batch is added into the raw materials to improve the performance of the finished polyamide-6 filaments, the produced polyamide-6 filaments has the antibacterial and uvioresistant functions. As the POY-DTY production process is adopted, the fluffiness and favorable elasticity of the polyamide-6 filaments are maintained, the compactness of the filaments is improved and the comfort degree of the end product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of nylon, in particular to a production process of nylon 6 filament. 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, density 1.15g / cm 3 , is the general term for thermoplastic resins containing repeating amide groups (-NHCO-) ​​in 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 short yarn. Nylon filament can be made into elastic yarn, and short yarn can be blended with cotton and acrylic fiber to improve its strength and elasticity. The common disadvantages of the nylon filaments in the prior art are that they are relatively hard, have poor elasticity, and have a bad sense of comfort. Contents of the invention [0003] In view of the deficiencies in the prior art...
