Yarn is one of the
most important elements of a carpet. It is produced of cotton. Yarn,

Hand-spun yarn is
only used for warp and weft of low priced carpets and rugs which are

this purpose, the hand-spun yarn is better than machine-spun. It is
less expensive and its packing is easier.
machine-spun yarn was produced mostly from India and imported to other
countries; but recently spinning workshops for yarn are established in

higher grade appropriates to the thicker yarn.
In past, there were
yarns thinner than 9 layers, but now it is substituted by silk. Yarn
number 20 is mostly used. Yarns utilized in carpet weaving and also
graded in connection with wale-counting are as follows:
