The properties of nylon

Nylon is a class of highly polar polymer materials that can form numerous hydrogen bonds be- tween molecules, resulting in a high melting point with a narrow melting range. This material exhib- its excellent mechanical properties, hydrophilicity, lubricity, wear resistance, corrosion resistance, oil resistance, and barrier properties, while being non-toxic and odorless. Additionally, its good pro- cessability makes it widely used in various industries.

<1> Core Challenges of Nylon Spinning Equipment

Overcome the three core challenges of nylon spinningprecise temperature control, efficient monomer ex.traction during spinning, and high-speed spinning technology,comprehensively ensuring fiber quality

<2> Nylon Spinning Equipment

Commonly used nylon fibers are mainly divided intotwo categories: Nylon 6 (PA6) and Nylon 66 (PA66)Since the melting point of nylon is lower than its de-composition temperature, nylon fiber spinning primarilyemploys the melt spinning method. For Nylon 6 (PA6)no drying and filtration device is required before spin-ning, with a spinning temperature of approximately260。Cand cross quenching temperature of around18。C.In contrast, Nylon 66 (PA66) requires dryingbefore spinning, with a spinning temperature above280。Cand cross quenching temperature of around18°C.
