Cellulose, a ubiquitous organic compound, stands as the most abundant biopolymer on Earth. It forms the primary structural component of plant cell walls, providing rigidity and strength essential for plant life. Beyond its fundamental role in the plant kingdom, cellulose finds extensive applications in various industries, including paper production, textiles, and the development of advanced…
Aramid Fiber, specifically focusing on the type known commercially as Nomex. While sharing the aromatic polyamide backbone with Kevlar, Nomex possesses a meta-aramid structure that imparts remarkable flame-resistant properties, making it crucial for protective clothing and other demanding applications. Aramid Chemistry Tailored for Flame Protection: As we discussed in the previous lecture, aramid fibers are…
Today, we are exploring the world of Specialty Fibers, a group of high-performance fibers engineered for demanding applications where exceptional properties are required. We will focus on two prominent examples: Aramid Fibers (exemplified by Kevlar) and Carbon Fibers, examining their unique characteristics, preparation, and remarkable uses. 1. Aramid Fibers: Strength and Heat Resistance 2. Carbon…
Welcome back to our textile fiber lecture series!
