布纹的疏密、粗细和布的品种、强力登记相关系。因为不一样纤维的模量、强度不同，因为这个要达到规定的强度，就要采取不一样直径、不一样旦数纤维、纱线，因为这个就显露出来了布纹的疏密、粗细方面的区别，普通来讲，聚酯要锦纶密，也要锦纶粗；强力高的布要比强力低的布密、粗。

The grain density, thickness and fabric varieties, strong registration system. Because of different fiber modulus and strength are different, because this will have the required strength, it should adopt different diameter, different denier fiber, yarn, because it revealed the differences of density, thickness, wove generally polyester nylon to dense, have high strength nylon coarse; cloth than the low strength of the heavier, crude.
