摘　　要：针对国内印染行业中织物回潮率在线监控的需求,首先基于电阻法回潮率测量原理设计了织物电阻测量回路,并搭建了织物标准回潮率控制平台,然后通过试验获取了纯棉、涤棉、黄麻3种常用织物的回潮率-电阻标定曲线;其次,设计开发了织物回潮率在线测试仪及相应的硬件电路与软件程序,该硬件电路主要基于电阻可调的分压机构实现,而回潮率计算则通过查表法获取。对测试仪进行的性能测试表明其误差在6%范围内;最后,将开发的回潮率仪应用于印染烘燥实际生产过程中,实现了对落布回潮率的在线控制,3个月的运行效果表明烘燥单位质量织物的蒸汽消耗量可降低7%以上。Aiming at the demand for online testing and control for fabric moisture in domestic dyeing and printing industry,firstly,a fabric resistance measurement circuit is designed based on the relevance of moisture-resistance,a platform for acquiring standard fabric moisture is also developed,and calibration curves of three typical kinds of fabric,such as cotton,polyester cotton and jute are obtained based on numerous testing results.Secondly,a fabric moisture meter for on-line measurement is developed,as well as corresponding hardware and software.The hardware mainly comprises adjustable voltage divider resistors and the software is developed based on look-table method.According to the characteristic test results,the measure error of the meter is less than 6％ ; the developed moisture meter is applied in industry cylinder drying machine for online moisture control of fabrics and the result of a three month field operation of the system proves that the steam for drying unit weight fabric can be reduced by more than 7 ％.
