All the students performed woefully in question 4. Only few students attempted the question. They were expected to explain the following terms as used in textile production as (i) Singeing: a process whereby a fabric is passed quickly over gas flame to burn off little hairs sticking out of the surface of the fabric
- Degumming : it is a process in the production of silk whereby the filaments are boiled remove sericin /gum
- Hacking : it is a process in the production of linen whereby the linen fibres are combed to remove short fibres and form parallel lines with the long fibres.
- Felting: it is the process of fusing fibres together using heat, pressure and moisture.
- Crocheting: it is the process of inter- locking yarns or thread into loops using a special hook.
