naptex FAQ 


Frequently Asked Questions: Naptex Textiles

Q. What is "Naptex?"

A. Naptex is a sophisticated yarn made from an NSP patented spinning process. It incorporates parallel stainles steel fibers at the yarn core, fully encapsulated by various textile fibers, specified in accordance to application.


Q. What can Naptex be used for?

A. Naptex is normally woven into durable fabrics used for garments, work drapes, upholstery, etc.  The most common applications are ESD (electrostatic discharge) garments and RF (radio-frequency) protection garments.


Q. What makes Naptex unique?

A. S tainless steel is an ideal material for conductive fabrics. However, in traditional steel-based conductive fabrics, the problem of steel fiber loss during use and washing can pose a problem, especially for electronics assembly environments.  The Naptex yarn construction assures no migration of fibers during the fabric life, providing extemely stable conductive performance.


Q. Suffused carbon stays in place too. Why should I prefer steel as a conductor?

A. Carbon performs well when new and is initially much less expensive.  However, it is a brittle material and will break down over time, resulting in conductive loss of the host fabric. Carbon also is vulnerable to heat and wash chemicals such as fabric softener. These characteristics mandate strict wash and care procedures to avoid losing ESD performance. In contrast, steel is flexible, impervious, and extremely stable, especially when spun into the yarn core.


Q. Is Naptex flame retardant?

A. Naptex can be treated with any of the common flame retardant processes. Because of Naptex's intrinsic durability and life expectancy, NSP makes a Nomex™ version for applications requiring flame resistance.  Nomex™ is DuPont's premium, permanant flame resistant aramid fiber.
