outline: none 0px !important; overflow-wrap: break-word !important;" align="justify">在实际生产过程中，织物纬密比经密小，主要因为：经丝采用的原料较好，上机张力大，丝线平整，丝光足，对织物的质地有较大影响。并且经丝线密度一般比纬丝细，有利于提高生产效率，在同样车速下，纬密小，产量高。此外，纬密小便于生产，当产生织疵时拆纬方便。<p style="text-align: justify;

outline: none 0px !important; overflow-wrap: break-word !important;" align="justify">经密与纬密之比，应依据经纬丝的线密度、组织结构和织物的使用特点而定。如乔其纱的经纬密度之比十分接近，一般不少于10％，而密度很大的缎织物。其经纬密度之比相差50％—60％。<p style="text-align: justify;

outline: none 0px !important; overflow-wrap: break-word !important;" align="justify">从新品种的设计来看，若无特殊的要求，平纹织物的纬密应小于经密20％—30％，斜纹为30％—40％，缎纹在50％左右为好。<p style="text-align: justify; margin-bottom: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(80, 68, 69); letter-spacing: 1.5px; background-color: rgb(255, 249, 244); vertical-align: inherit; max-inline-size: 100%; cursor: text; font-family: system-ui, -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;

outline: none 0px !important; overflow-wrap: break-word !important;" align="justify">如果单层织物出现纬密大于经密的情况，是不合理的，应力求避免。但重纬织物，特别是多色纬组成的提花织物，可能纬密会大于经密，这是结构的需要，可作为特殊情况处理。 </section></section>
