line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">一个基本概念：纱线的支数是不可以进行数学计算的，当我们想要计算合股的纱线支数时，可以先计算出纱线的号数，号数是可以进行加减计算的，再通过计算得出的号数，算出合股后的纱线支数</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">例如：C40/2</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">40s的纱线号数为583.1/40=14.58，</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">那么合股纱线（40/2）号数为14.58*2=29.16，</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">由此得出合股纱线（40/2）支数为：583.1/29.16=20s</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">虽然得出的结论和40/2=20是一样的，但是从过程可以看出是要经过两道换算才能倒出来，这个计算方法一样适用于弹力纱的。</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">例如：16/70d包芯纱</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">16s的号数为583.1/16=36.45</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px;"><span style="font-family: 微软雅黑, sans-serif;">70d的号数&nbsp; 70d / 9 / 3.5(</span><span style="color: rgb(46, 116, 181); font-family: 微软雅黑, sans-serif;">弹力丝牵伸倍数</span><span style="font-family: 微软雅黑, sans-serif;">)=2.22</span></span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">包芯纱（16+70d）的支数为：587.6/（36.45+2.22）=15.2s</span></p><p style="vertical-align:inherit;text-indent: 32px; line-height: 2em;"><span style="font-size: 15px; font-family: 微软雅黑, sans-serif;">从弹力纱和股线的支数计算可以得出，纱线支数的计算不仅仅是通过简单的相加减就可以得出的，<span style="color: red;">我们需要将纱线的支数转换为号数，再由号数进行数学计算，最终得出纱线的支数。（这一点非常重要！！！）</span></span></p><section class="_135editor" data-role="title" data-tools="135编辑器" data-id="107662"><section style="text-align: center;margin: 10px auto;" class=""><section style="display: inline-block;"><section style="display: flex;justify-content: center;align-items: flex-end;margin-right: 5px;"><section class="assistant" style="width: 45px;
