摘要
This work focused on effects of an eco-friendly carrier JYK on thermal properties,dye uptake,color yield(K/S values)and color fastness of recycled polyester knit fabrics.The study also explored optimization of the low-temperature carrier(LTC)dyeing and compared its dyeing performance to the high-temperature and high-pressure(HTHP)dyeing.Results showed that the eco-friendly carrier JYK had an obvious plasticizing effect on recycled polyester,which significantly reduced the glass transition temperature,thereby reducing the dyeing temperature and benefiting low-temperature dyeing.The optimal dyeing conditions were determined as follows:the disperse dye was 2%on weight of fabric(owf)and the eco-friendly carrier JYK was 2%owf at 98℃dyeing temperature for 60 min.Compared with the HTHP dyeing,there was no significant difference in the K/S values and color fastness of recycled polyester fabrics dyed in the low-temperature method which demonstrated that the low-temperature method could be totally accepted.This study indicated that the low-temperature dyeing with a carrier JYK could be an effective and sustainable method for dyeing recycled polyester.
