底网热定型是BOM毛毯生产过程中的一个关键环节，对毛毯的尺寸稳定性有重要的影响。通过改变底网热定型中的温度和时间两个参数进行试验，并测试了定型前后底网的横向收缩率、厚度压缩率、压缩回弹性和拉伸性能。试验结果表明，锦纶66底网热定型最适宜的定型时间为40 s，定型温度需控制在185～195℃范围内，BOM毛毯的热定型温度可高于205℃。在上述条件下进行热定型，可以提升底网以及整个毛毯的尺寸稳定性和使用性能。

Bottom web heat-setting is a key point which influences the dimensional stability of BOM papermaking felt in the production process.Experiments on the bottom web by changing the temperature and time in heat-setting have been done.The lateral shrinkage, thickness compression ratio, compression resilience and tensile property of the bottom web have been tested before and after the heat-setting.Experiments showed that the optimum time of PA66 bottom web heat-setting was 40 s and the optimum temperature was 185~195 ℃.The temperature of felt heat-setting can be over 205 ℃.Under these conditions, the dimensional stability and use performance of the bottom web and the felt can be enhanced.
