Introduction to textile weaves and design
Objectives: At the end of this lesson you shall be able to
• explain weaves and designs used in textiles
• explain plain weave and its derivatives
• brief rib weave and matt weave
• understand the principles behind various ornamentation techniques applicable to plain weave.

influences the aesthetics as well as the properties of the
woven fabrics. The interlacement patterns of the woven
fabrics are manipulated using the drafting order and the
lifting plan.
The weaves are constructed on a graph/point paper using
(X) cross marks and blanks. A cross mark in the point
paper means that the warp is lifted over the pick, whereas
a blank means the weft end passing over the warp end.
Woven fabric structures may be broadly divided into two

purposes.
Weaves, draft and lifting plan
Weaves are the pattern of interlacement of the
corresponding warp and weft threads. A weave repeats
on a definite number of ends and picks and the number
of ends and picks in a repeat may be equal or unequal. 3 Skip draft: Skip drafts system is useful in weaving
