Superfine pigment dyeing of silk fabric by exhaust process

The surface of silk is modified by a cationic reagent, N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride(CHTAC) in order to enable the fibre to be dyed with superfine pigments by an exhaust process. The effects of cationization pretreatment conditions such as the amount of cationic reagent, pH, treatment temperature and time on color yield are discussed in detail. The result shows that the condition suitable for modification treatment is that the concentrationc of cationic reagent is 10 g/l, pH 8, liquor to goods ratio of 100:1 and 60°C for 30 min. The white index decreases with the increase of alkali of cationic treatment. The crock fastness and wash fastness of silk dyed by pigment exhaust dyeing achieve 3–4 and 4 scale, respectively. The treated silk fabrics still retain a soft handle because the bending rigidity B and hysteresis 2HB increase slightly after cationization pretreatment and dyeing procedure. It has been demonstrated that properties of surface modified silk dyed with superfine pigment by exhaust process are acceptable.     

Effect of pineapple protease on the characteristics of protein fibers

A pineapple protease, bromelain, was used to improve the dyeing properties of protein fibers such as wool and silk. The optimal condition for the activity of the pineapple protease was about 60 °C at pH 7. The wool and silk were treated with the protease extracted from a pineapple and the K/S values of the dyed wool and silk were measured using a spectrophotometer in order to compare the dye uptake. The protease treatment enhanced the dyeing properties of protein fibers without severe changes in mechanical properties. The surface appearances of protease-treated fibers were observed by microscopy.
