min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"> 由于影响织物经、纬纱紧度与密度的因素很多,上述几种计算公式均无法全部加以概括,计算所得结果总会有某些偏差。实际上,在产品设计时,往往先参照类似品种来初步确定,然后通过生产试织加以修正。而且,一定品种的织物总有自己特定的紧度范围,这是由它的性能与风格所决定的。即使是新的织物品种也往往是在类似品种的基础上发展而来的。因此,设计者应当熟悉各种织物的紧度范围和产品规格。</p><p style="max-inline-size: 100%;
