Broken twill is formed by breaking the twill line of basic twill. Normally straight draft is used to produce this weave. Rearranged twill is produced by the rearrangement or transposition of the original order of the threads in the regular basic twill.
Fabric Engineering
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.
Motion of Loom
Shedding is the operation by which the warp is divided into two sheets so that sufficient gap is created for the uninterrupted passage of the weft from one side of the loom to the other.
What Is Loom | Classification Of Loom
The weaving m/c is technically termed as loom .The loom is a device or m/c in which interlacement of warp and weft yarn performed and thus fabric is produced. In 1930's, eventually, each weaving machine driven individually by an electric motor was developed, this loom drive concept has remained in use until the present.
Types of Drafting Plan
The various drafts are classified as follows:Straight draft,Skip draft,Satin draft,Pointed draft,Broken draft,Divided draft,Grouped draft,Combined draft,Curved draft.
