Nylon is the first commercially successful synthetic fiber. This material is known for its high performance in textiles.
However, not many know it was vital for industry and even played a big role in World War II.
This article will help you understand several key attributions about nylon.
What is Nylon?
In this part, let’s see the definition, and how to produce nylon.
Definition of Nylon
Nylon is a synthetic polymer, specifically a type of polyamide.
It is known for its outstanding strength, elasticity, and resistance to abrasion, making it a popular choice in various applications, from textiles to engineering materials.
History of Nylon
The history of Nylon dates back to 1935 when Wallace Carothers and his team at DuPont successfully synthesized it.
In the 1930s, Japan exported most silk but did not get along with the US. This political event reduced the silk supply to the US. This situation made the US decide to make something else instead of silk.
The introduction of Nylon revolutionized the textile industry. It paves the way for the development of numerous other synthetic fibers. In those days, the predominant use of nylon was women’s stockings and toothbrush bristles, which gained immense popularity in the late 1930s.
Later, nylon was found to be useful in the defense. In WWII, it was used to make parachutes, body armor, and other combat gear.
The use of nylon materials is credited by many military fans as a key reason why the U.S. beat Japan.
How does Nylon Fabric Made?
The nylon manufacturing process primarily involves:
- Heating caprolactam(a cyclic amide): It begins with heating caprolactam to high temperatures.
- Ring-opening polymerization: Under high temperatures, caprolactam will undergo a reaction known as ring-opening polymerization. During this phase, the monomers link together to form long chains of nylon.
- Cool and solidify: Once the polymerization is complete, the resulting nylon resin is cooled and solidified.
- Extrusion: Following solidification, the nylon is typically extruded into a filament or granule form, depending on the intended application.
- Drawing process: The extruded material can be drawn or stretched to improve strength and elasticity. This process aligns the polymer chains, enhancing the mechanical properties of the nylon.
- Finishing treatments: Finally, the nylon is subjected to enhance its durability and performance characteristics.
