Textile Materials (in Chinese), 2nd ed., Textile Industry Publishing House, 1990 Justification Textile materials are the basic materials. It is crucial to establish a basic understanding of the science governing the behavior of these materials. The course is taught in a bilingual system such that the students will have an opportunity to enhance their English ability while learning the key knowledge in textiles. Grading Grades for this course are determined by homework (10%), two tests (30% each) and one final exam (30%). The final grade will be from A to F corresponding to the total score according to the student handbook. Attendance Attendance is mandatory. A class roll will be taken at the beginning of each class. Missing every three times without reasonable excuses in the semester will have course grade deducted 10 points or one letter grade. A perfect attendance record will be rewarded 5 points in their total course grade. Honor Code Students will be expected to adhere to the guidelines for academic integrity. That means that ANY action that goes against the rules set forth when giving homework or test or taking class roll will be dealt with in a very strict fashion. Grades are valuable: honor and integrity are priceless. Topical Outline Introduction Reading assignment Textbook: Kathryn L.
