Other than the classroom and laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group and prepare reports of about 5 pages for each activity, also collect/record physical evidences for their (student’s) portfolio which will be useful for their placement interviews:
- Survey market for different synthetic fabrics and compare them based on their properties, applications, and prices. Present the results
- Prepare chart on – Physical and chemical properties of synthetic fibres.
- Prepare presentation incorporating visuals, photographs, animations, video on process sequence of synthetic fibres.
- Library/ internet survey regarding yams and fabrics used in different industries.

Suggested Micro-Projects
Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.
The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs.
A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:
- Product list sample: Visit industries and market shops and collect at least 20 product samples made by using polyethylene and polypropylene nonwovens. Find the current prices and their end uses. Compare prices of similar products made of other materials.
- Fibre properties: Collect fibre samples of 10 synthetic fibres, check their physical and chemical properties in the institute laboratory, and prepare presentation.
- Class of fibres: collect samples of synthetic fibres from the industries, find their class using relevant method in the institute laboratory, and present the results.
- Polyester fibre applications: Collect information about 10 applications of modified polyester fibres in technical textiles and prepare power point presentation
- Nylon fabric samples: Collect 10 fabric samples made from nylon, check their fabric particulars EPI, PPI, type of weave, etc., and prepare catalogue containing fabric swatches swatch.
- Acrylic blends: Collect 10 fabric samples containing acrylic as blend, check their blend composition, and present the results with application of each blend for suitable end uses.
