The bushing additionally controls the fiber yield or yards of fiber in step with pound of glass. (The metric unit, tex, measures fiber linear density; 1 tex = 1 gram/kilometer, and yield is the inverse, yard/pound.) A fiber with a yield of 1,800 backyard/pound (275 tex) might have a smaller diameter than a 56 backyard/pound (eight,890 tex) fiber, and an 800-nozzle bushing produces a smaller yield than a 4,000-nozzle bushing. This helps to explain why Wisdom Dzotsi, Americas glass commercial enterprise supervisor for OCV storefront signs Reinforcements (Toledo, Ohio, a aggregate of the reinforcements and fabric organizations of Owens Corning and Saint-Gobain Vetrotex), perspectives a four,000-nozzle bushing as the sweet spot that has developed for optimizing production flexibility. In comparison, AGY uses 800-orifice bushings due to the fact, as Walker explains, “We are a smaller organisation whose glass yarn and uniqueness fiber enterprise is based totally on finer filaments and smaller-run niche merchandise.”
Fiberglass, or “glass fiber,” similar to Kleenex, Thermos—or even Dumpster—is a trademarked call that has turn out to be so familiar that humans usually handiest think about one component after they pay attention it: Kleenex is a tissue; a Dumpster is an outsized trash bin, and Fiberglass is that fluffy, purple insulation that traces the attic of your home, proper? Actually, that’s most effective a part of the story. While the Owens Corning Company did trademark the near-ubiquitous insulation product known as Fiberglass, fiberglass itself has a familiar base structure and a extensive form of makes use of.
