The diameter of fiberglass tül
monofilament is generally several microns to twenty microns, which is equivalent to 1/20-1/5 of a hair.
Crude fiber: Its monofilament diameter is generally 30 μm.
Primary fiber: its monofilament diameter is greater than 20 μm.
Intermediate fiber: monofilament diameter 10-20μm.
Advanced fiber (also known as textile fiber): its monofilament diameter is 3-10 μm.
Glass fibers with a monofilament diameter less than 4um are also called ultrafine fibers. Different diameters of monofilaments not only have different properties of fibers, but also affect the production process, output and cost of fibers. Generally, 5-10um fiber is used for textile products, and 10-14um fiber is generally suitable for fiberglass weave

The diameter of the monofilament is determined by the diameter of the platinum bushing and the wire drawing speed. Generally, the thinner the monofilament, the more expensive the fiber cost. On the one hand, it is related to the difficult production process and low yield; on the other hand, the finer the monofilament, the more coupling agent per unit area.
