Polyamide (nylon) fiber production

In the production of polyamide nylon salt, caprolactam and polymer solution concentration of real-time monitoring

Nylon 6 - is the polymerization reaction of adipic acid and adipic amine to produce the fully synthetic fibers.

Adipic acid reaction with adipic amine to produce the six methylene diammonium adipic acid, commonly known as nylon salt.

In this process, adipic acid first six methylene two ammonium solution concentration in the evaporator, and then add in acetic acid to stabilize the chain length.After evaporation, the salt solution heat and remove the remaining water.TiO2 dispersant and aggregated.Next, the melt viscosity of the polymer to squeeze through the autoclave, extrusion wheel.

Nylon 6 (caprolactam) is a kind of polymer fiber, only made from one kind of ingredient: caprolactam.Its melting point is lower than nylon 6-6, but excellent dyeability, elastic and light fastness.

Visa K - PATENTS^®In situ online refractometer nylon salt, caprolactam and used to measure and control the concentration of polymer solution.
