摘　　要：目前，利用乙二醇（EG）回收废弃涤／棉混纺织物时，加入EG的量远大于织物的量，为了降低回收成本，减少污染，需要对部分EG回收再利用。文章研究了回收温度、方法，以及醇解液存放状态对EG回收再利用的影响。研究表明，醇解液密闭保存，回收温度在196～198℃之间，所得EG纯度较高，含水率较低，可以满足醇解涤／棉混纺织物的要求，其醇解曲线和工业用EG曲线接近，醇解效率较高。What ethylene glycol recycled polyester has been achieved industrialization, at present, there are a lot of research of ethylene glycol （EG） recycling waste polyester/cotton blended fabric, however, using ethylene glycol （EG） recycling waste polyester-cotton blended fabric, the amount of EG is greater than the weight of fabric. In order to reduce the cost of recycling, it needs to recycling part of EG. It researches the recovery temperature, recovery method, and alcoholysis liquid storage status of EG recycling. Studies have shown that aleoholysis liquid sealed preservation, recovery temperature between 196-198℃, recycling EG is relatively higher, moisture content is relatively lower, the reaction of recycled EG and polyester-cotton blended fabric is almost unanimous to fresh EG, the efficiency is higher.
