The density of fabrics refers to the sum of warp and weft yarns per square inch. The density of fabrics is generally represented by the letter "T". Usually, higher number of density of fabric is more durable. Conversely, the lower number of density of fabric has larger gap in the cloth and the lower durability of use.



I use this magnifying glass for observing cloth to see the quality and the number of density of fabrics. The square space under this magnifying glass is one square inch.



As you can see above, in an area of ​​one square inch, this piece of 600D Polyester fabric has 44 warps and 28 wefts. The total number of density of fabrics is 72T.
