Class Times: Tuesday and Thursday 3:10 - 4:00 pm - AG 3028
Laboratory - 1:10-4:00 Wednesday
Course Objectives:
The purpose of this course is to gain an understanding of what quality control means and why it is important. The variety of laboratory tests and standards available to assess the various aspects of textile/apparel quality will be discussed. Students will be given hands-on opportunities to conduct testing, as well as the decision making skills needed to determine and manage successful production. The performance specifications of textiles materials will be examined to determine if they are suitable for desired end-uses. An introduction to the philosophy behind the role of garment analysis relative to meeting business and consumer needs.
Grading Scale:
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
< 60 F
| Attendance and participation* | 20% |
| Laboratory reports | 40% |
| Quality assessment assignments | 10% |
| Final specification assignment | 30% |
| Total | 100% |
Attendance Policy: No more than three unexplained absences. Due to the large amount of time to be spent working in the laboratory, it may be difficult for the student with an excess of three absences to get the required laboratory assignments completed.
*Participation is more than mere attendance. Students will be expected to participate in class discussions and ask questions. When working on laboratory assignments in groups, each member of the group will be expected to contribute equally.
