padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">　　(1)紧度法：利用紧密织物紧度的公式求出织物的最大紧度和密度[式(1-15)～式(1-17)]。达到紧密织物紧度时的密度为最大理论密度以Pjmax(经向最大理论密度)和Pwmax(纬向最大理论密度) 表示。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">　　一般情况下，织物一个方向达到最大紧度(密度)时，另一方向往往小于最大紧度(密度)。由于纱线具有黏弹性和可压缩性，为此不少织物其紧密方向的纱线可通过计算求最大的密度值。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">　　采用紧度法计算织物的经密和纬密，是利用在求得紧密织物的最大密度后，再分别乘以设计所要求的织物经向紧密率(K<sub style="max-inline-size: 100%; margin: 0px; padding: 0px; font-size: 10.5px; overflow-wrap: break-word !important; outline: none 0px !important;">J</sub>)和纬向紧密率(K)，即得到设计织物的经密和纬密。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">　　紧密织物是经纬纱在织物内的排列可能达到的最大紧密情况，但在实际织物中，一般是达不到如此程度的，为了确切地比较各种实际织物的紧密程度，提出以紧密率K来表示，其含义即：实际织物的紧度E实对该组织相同结构相时的紧密织物的紧度历紧之比值。计算公式如下：</span></p><p style="max-inline-size: 100%; clear: both;
