                       (ii)         luster;
                       (iii)        absorbency.
           (b)        Give two examples of each of the fibres in (a) above
           (c)         State three reasons for making blended fabrics.
           (d)        State two advantages of each of the following blends:
                       (i)          Wool and polyester;
                       (ii)         Cotton and nylon.


They answered the questions on differences between natural and synthetic fibres very well and did not perform well on advantages of blends.

The required answers to the questions are as follows:

(a)       Differences between natural and synthetic fibres







Obtained from nature

Obtained from chemicals



Less lustrous

Very lustrous



Very absorbent,

Less absorbent



Absorbs dye easily

Does not absorb dye easily

        (b)       Examples of the natural and synthetic fibres

      (c)       Reasons for blending fabrics

                                                     (i)      To produce variety of fabrics
                                                    (ii)      To avoid mill waste
                                                   (iii)     To improve wearing qualities/durability to be comfortable to wear.
                                                   (iv)     To reduce production cost of fabric
                                                   (v)      Combines the advantages of both fibres while minimizing their disadvantages.
                                                   (vi)     To improve launder ability.

                                                   (viii)   To strengthen weaker fabric
                                                    (ix)    To make fabric more absorbent
                                                     (x)     To improve texture

          (d)       Advantages of the following blends

                  (i) Wool and Polyester
         - Makes the fabric washable
