UNIT I 9
Pretreatment: Chemical composition of wool – Scouring of wool – Scouring in the form of
loose wool, yarn and fabric – Milling, Grabbing and potting. Bleaching of wool –
Carbonizing of wool – Chemical composition of silk – Degumming of silk with alkalis,
Organic acid, organic amines and enzymes. Machines for degumming of silk yarn and
fabrics. Bleaching of silk with reducing and oxidizing bleaching agents.
UNIT II 9
Acid Dyes: Types based on application – Properties - Effect of electrolyte, temperature,
time, pH and other dye bath assistants on dyeing of protein fibres Importance of
isoelectric point in dyeing of protein fibres. Mechanism of dyeing protein fibres.
Application procedure for dyeing of wool, silk, stripping and re-dyeing.
UNIT III 9
Reactive Dyes: Types of reactive dyes used for dyeing protein fibres – Type of chemical
reactions involved in dyeing of wool and silk with reactive dyes – application of
monochloro, dichloro triazine dyes on wool and silk – application of vinyl sulphone,
difluoro, mono chloro primidyl dyes, bromo acrylamide dyes and bifinctional dyes on
wool and silk. Striping and redyeing.
