Student Activities
- Prepare a chart showing routine tests conducted for fibres, yarns, fabrics and garments and the instrument used for the same.(PO2,PO3,PO4)
- Visit a spinning mill and take a note of sampling methods and number of tests conducted for texting different fibre, yarn and fabric.(PO2,PO3)
- Take a hygrometer from the lab, find out the relative humidity in different laboratories in the department(PO1,PO3)
- Go to a ginning mill, Collect a sample of cotton from the loose cotton storage area and from stored bale, find out the moisture % in the laboratory and compare. Report the observations.(PO3,PO8)
- Prepare a chart showing fastness ratings of dyed fabrics for different media of colour fading. .(PO2,PO3,PO6)
- Measure the moisture regain of the cotton and polyester yarns individually and also measure the moisture regain of blended yarn. Compare these values to check the formula for moisture regain of blend component. .(PO2,PO10)
- Collect suiting and shirting fabrics, compare their properties by measurement and submit a report Collect Polyester and cotton fabrics, compare their properties by measurement and submit a report .(PO2,PO3)
