Environmental friendly carrier preparation and its application in one-bath dyeing of wool/polyester fabric北大核心

In order to decrease polyester dyeing temperature, and realize one-bath dyeing of wool, polyester blended fabric, environmental friendly inodorous carrier emulsion with good stability was preparation, the effects of carrier on polyester glass transition temperature, dyeing temperature and carrier amount on polyester dyeing performance were investigated, and solving method of disperse dye staining wool after one-bath dyeing of wool and polyester was discussed. The results showed that carrier had obvious plasticizing effect, polyester can be dyed at 98 °C by using the carrier, the optimum carrier amount was 5% (owf). After one-bath dyeing of wool and polyester, reduction cleaning at 75 °C for 10 min with bath ratio 1 = 50 by using solution containing sodium hydrosulfite 0.6 g/L, sodium carbonate 1.0 g/L, and anionic surfactant AES 1. 0 g/L, which could solve the problem of disperse dye staining wool.
