Problems solved by technology

Nylon has always occupied an important position in the clothing industry and is one of the commonly used clothing fabrics. However, because it is easy to pill and generate static electricity, the surface resistance of nylon materials in the prior art is 10 12～15 Ω, the charge accumulated on the surface is difficult to dissipate, which brings a lot of trouble to processing and application, affects its wearing performance and reduces the quality of fabric

Abstract

The invention discloses a preparation technology for antistatic nylon. The preparation technology comprises the following steps: (1) weighing the following components in parts by weight: 30-70 parts of nylon chips, 5-15 parts of an antistatic agent, 1-10 parts of a compound of an anionic surfactant and a nonionic surfactant, 2-10 parts of a conductive filler, 5-10 parts of glass fiber, 0.5-2 parts of an anti-oxidant and 2-10 parts of a dispersant; 2) drying the nylon chips, mixing the dried nylon chips with the compound of the anionic surfactant and the nonionic surfactant, the conductive filler, the glass fiber, the anti-oxidant and the dispersant, placing the mixture into a screw extruder, and performing extrusion and pelletization to obtain the antistatic nylon. The nylon prepared according to the preparation technology is high in antistatic effect.

Description

technical field [0001] The invention relates to the technical field of nylon, in particular to a preparation process of antistatic nylon. 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. Nylon has always occupied an important position in the clothing industry and is one of the commonly used clothing fabrics. However, because it is easy to pill and generate static electricity, the surface resistance of nylon materials in...
