Suggested Student Activities:
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 (students) portfolio which will be useful for their placement interviews:
- Market survey of different yarns of natural and man-made origin of different yarn numbers based on application and price.
- Library survey of different yarns used in the industry with respect to name of manufacturer, current price, counts of yarn and blend proportion.
- Prepare table for norms published by different research organizations for different yarn properties for various types of yarns.
- Prepare question bank referring old MSBTE question papers for yarn testing.

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 he 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:
- Yarn Numbering: Collect yarns of different yarn number and prepare a chart from higher number to lower number in each system. Also prepare a chart for conversion of yarn number from one system to another.
- Yarn Numbering: Each batch will solve 50 numerical on yarn numbering.
- Yarn Twist: Collect different yarn samples used for different applications like hosiery, warp, weft, voile, fancy yarn, crepe yarn. Identify direction of twist and calculate amount of twist and twist multiplier. Prepare chart for the same.
- Yarn Evenness: Collect and prepare chart of yarn samples for different faults like thick, thin, neps and also collect norms for imperfections of at least 10 counts.
- Yarn Hairiness: Collect 10 yarn samples from course to fine, measure yarn hairiness by optical method. Plot a graph of hairiness parameter against count and interpret the result.
- Tensile Strength: Draw schematic diagrams of different principles and instruments based on them for tensile strength testing. Test two yarn samples of different counts on these instruments and prepare a chart for test results.
- Testing of Synthetic yarn: Collect 5 samples of texturised yarn and calculate crimp rigidity and crimp contraction.
- Testing of Synthetic yarn: Collect 5 samples of synthetic yarn, heat set the same at different temperatures varying from 180 to210C. Test dimensional stability by hot boiling waler test method.
