吸湿改性PET的研发

Research and development of hygroscopic modified polyester

在PET生产中通过在线添加吸湿保湿无机颗粒与亲水性有机基团,使PET纤维不但具有吸湿排湿的功能,而且还赋予PET纤维一定的保湿功能。通过调节添加剂的加入量来调整PET纤维的回潮率。

In polyester production process, by online adding moisture absorption inorganic particles and hydrophilic organic groups, the polyester fiber not only has the function of moisture absorption, but also has a certain moisturiz- ing function. The moisture regain was adjusted by adjusting the additive adding amount.
