Course Title: Pigment Processing: Physico-Chemical Principles

Credit: 2.5      Total Semester Credit Hours: 40

Lecture Hours: 48         Experiment/ Computer Hours: 0

Major: Textile Chemical and Dyeing Engineering

1. Course Goals and Objectives

Pigment Processing: Physico-Chemical Principles is a key course for the foreign postgraduate students majoring in Textile Chemical and Dyeing Engineering. The course is to help foreign postgraduate students to extend their knowledge on physic-chemical principles of pigment application technology and pigment manufacturing or processing industry. The main content of the course are: physical characterization of pigments, optical properties of pigmented systems, rheological behavior of pigment dispersions and dispersion process.

2. Course Requirements

Pigment Processing: Physico-Chemical Principles course is instructed in multi medium for foreign postgraduate students. The course enables the students to acquire a solid base of knowledge in physical and physic-chemical features of pigment application. The classes, such as the principle of Dyeing and Finishing Technology, Dye Chemistry and Color Science will contribute to this class.
