for monofilament filament, the round diameter is about 214 micron
for multi filament yarn depends to cross section of fibers and the rate of twisting
Polyester 420d refers to a specific type of polyester fabric characterized by its denier measurement of 420. Denier is a unit of measurement that indicates the thickness of the individual fibers, with higher numbers indicating thicker fibers. This particular weight makes 420d polyester durable and resistant to wear, making it suitable for a variety of applications, including outdoor gear, bags, and industrial uses. The fabric is typically water-resistant and easy to clean, contributing to its popularity in both fashion and functional textiles.
Denier nylon is a unit of measuring the thickness/weight of a thinly spun fiber. It indicates the material's durability, plus the fineness of fiber filaments and yarns - both natural and synthetic. The higher the denier, the thicker the fiber; the lower the denier, the finer the fiber. per Wiki answer to what is denier.
420 micron = 0.42 millimeters
No, 420 denier nylon and 4 oz are not the same; they refer to different measurements. Denier (den) measures the thickness of the fibers in the fabric, while ounces (oz) typically refer to the weight of the fabric per square yard. A 420 denier nylon fabric is relatively durable and strong, while 4 oz indicates a lighter weight fabric. The two measurements provide different information about the material's properties.
600D polyester is generally considered stronger than 420D polyester dobby due to its higher denier (D) rating, which indicates a thicker and more durable fabric. The denier measurement reflects the fiber's weight and density; therefore, 600D has a greater tensile strength compared to 420D. However, the specific strength can also depend on the fabric weave and treatment, so it's essential to consider the intended use when comparing these materials.
The ballistic nylon will be a higher denier (thickness of the thread). Also will be shiny/glossy compared to the matte finish of polyester. Ballistic nylon will be much more durable and much less likey to tear or scuff. You can get higher denier polyester (900, 1200, 1800) which will be better for wear and tear. The price will reflect this however as 600d poly is low to mid price point whereas the others are higher.
420 dernier nylon is stronger than 150 dernier nylon. The "dernier" measurement refers to the thickness of the fibers, with a higher number indicating a thicker and generally more durable material. Therefore, 420 dernier nylon has a greater tensile strength and is better suited for applications requiring more durability and resistance to wear.

4203 = 420 x 420 x 420 = 74088000
21% of 420= 21% * 420= 0.21 * 420= 88.2
95% of 420 = 399 = 95% * 420 = 95%/100% * 420 = 0.95 * 420 = 399
88% of 420= 88% * 420= 0.88 * 420= 369.6
