涤纶超细纤维的染色

Dyeing of Superfine Polyester Fibre

针对涤纶超细纤维染色时退浆不易，上染速率太快，染色均匀性和渗透性差，易产生折皱、擦伤，日晒、升华及湿牢度下降等问题，探讨了超细纤维的起始染色温度，升温速率，染料选用，折皱和擦伤的防止，染浴的一般组成和染色工艺等。

In order to tackle problems in dyeing superfine polyester fibre,i.e., difficult degumming,quick dyeing rate, poor dyeing evenness and permeability, easily creasing and chafing, lower fastness to light, sublimation and water, investigations are made into its initial dyeing temperature,temperature rising rate, dyestuff selection, crease and chafe prevention, normal dyeing bath components, and dyeing technology.
