Relation Between Yarn Count and Diameter & count calculation for ply yarn

Normally, when two single yarns are twisted together one should expect some contraction or some increase in length depending on the twisting direction. A contraction will result in a yarn slightly coarser than the estimated value. In order to correct for this difference, typically 5% to 10% contraction or extension should be accounted for.

Derivatives of Plain Weave

There are two types of derivatives : Rib and Matt. In rib weave, it produces rib or cord effect in warp/weft direction. Used as grosgrain cloth, mattress cloth,hair cords, blankets etc. Matt is constructed by extending the plain weave both vertically and horizontally. Matt weave finds extensive uses for a great variety of fabrics such as dress materials, shirtings, sail cloth, duck cloth etc.

Twill & Angle of Twill Weave

A twill weave is characteristics by diagonal ribs (twill lines) on the face of the fabric. These twill lines are produce by letting all warp ends interlace in the same way but displaing the interlaceing points of each end by one pick relative to that of the previous end while the plain weave can only be woven in one form, there exit several options with regrad to twills.
