This difference in weight is due to the texture of these two fabrics. Plain targal has a square texture, but Twill fabric has a texture with a density of 280 to 290 grams, which is why targal Twill fabric is thicker and more durable. About 50 to 55 grams of natural viscose fibers are used per meter of targal Twill fabric, which comprises 18 percent of the total fabric.
