Which unit of weight is used to measure the fineness of nylon?
Ballistic nylon refers to the weight, not the strength, of the fabric. Laboratory tests have shown that double weave 1050 denier fabric is the strongest and most durable fabric for its denier weight level. The 1680 denier has a similar strength but lighter weight than the 1050, and it resists abrasion and tearing. Ballistic nylon is hard to dye, so it is often found in black or similar dark colors. Ballistic nylon Ballistic nylon is a thick, tough, nylon fabric with several uses. Ballistic nylon was developed by the DuPont corporation as a material for flak jackets to be worn by World
Fineness Fineness The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of "fine metal" therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10%
