CONTENT, ASSESSMENT AND WORKLOAD

Content
  • valid for whole curriculum period:

    This course covers the basic principles for the textile coloration/dyeing, textile dyes, and textile printing. It explores the application of various dyes in the coloration of the most important (a) natural fibers, including cotton, and wool, (b) regenerated fibers from natural biopolymers, and (c) synthetic fibers, including polyester, polyamide, and polyacrylonitrile fibers. The course aims to provide a background for the preparation, dyeing, and printing of natural and synthetic textile goods. The environmental and sustainability aspects of textile coloration will be also highlighted.

    The following topics will be covered in this course:

    Introduction to textile fibers and dyes
    Introduction to Color Physics
    Introduction to Color Chemistry
    Acid dyes for coloration of wool and other polyamide fibers
    Direct dyes for coloration of cellulosic fibers
    Vat dyes for coloration of cellulosic fibers
    Reactive dyes for coloration of cellulosic fibers and wool
    Disperse dyes for coloration of synthetic fibers
    Cationic dyes for coloration of acrylic fibers
    Textile machinery
    Environmental aspects of textile coloration
