The Manufacture and Dyeing of Cationic Dyes Dyeable Linen Fibers
Sulphonated linen fabrics dyed with cationic dyes were prepared by chemically modifying linen fabrics oxidated by sodium periodate with hydrogen sulfite sodium. The effect on aldehyde group content and breaking strength of linen fabrics by oxidation conditions was investigated, the influencial effects of sulphonated by the concentration of hydrogen sulfite sodium, processing time,reaction temperature and so on were Analysised,the optimal oxidating and sulphonating process conditions of linen fabric were not only determined by means of infrared spectrum and the dyeable behevior of sulphonated linen fabrics with cationic dyes,but also the sulphonated linen fabrics dyed with cationic dyes have higher dye up-take, better colour fastness and levelness and more remarkable permeability.
