Twill Weave

• Twill Weave: • Twill weave is a kind of weave that repeat on three or

more ends and picks and produces diagonal line on the face of fabric.

• In a regular twill the diagonal line or twill line produces at 45 degree angle with the horizontal.

• Concept: • The most characteristic of twill is that they have

diagonal lines on the cloth.

Derivatives of Twill Weave:There are many derivatives of twill are given bellow:• Broken twill. • Combined twill. • Diamond design. • Diaper design. • Diagonal design. • Elongated design. • Herring bone twill. • Shaded twill. • Stepped twill. • Zigzag/waved/pointed twill weave.

Zigzag/waved/pointed Twill Weave:

• It is the simplest and one of the most important modifications of twill weave produced by reversing the direction of twill at suitable interval

A point is selected(usually the last warp is selected) as the reversing point and so it is sometime call as point twill. In this twill pointed or straight draft is used.

This twill is produced by combining S and Z twist. According to reversing of direction there are two type of zigzag twill:

• Horizontal zigzag twill. • Vertical zigzag twill.

Horizontal zigzag twill:

• When the reversal direction of twill line occur upon the warp yarn, it result a horizontal zigzag twill, Here the basic twill is extended in warp direction. Here the number of warp yarn in a repeat is double of the number of weft. In horizontal zigzag twill pointed draft is used.

Horizontal zigzag twill:

Vertical zigzag twill

• When the reversal direction of twill line occur upon the weft yarn, it result a vertical zigzag twill, Here the basic twill is extended in weft direction. Here the number of weft yarn in a repeat is double of the number of warp.In Vertical zigzag twill straight draft is used.

Vertical zigzag twill

Herring Bone Twill

This twill are constructed in a different manner from the ordinary zigzag twill. Though it also depend on reversal of twill direction

Here reversal direction occurs after a middle line.Here at first the basic twill is drown then the number of central point is selected in zigzag

• In herring bone twill straight draft is used.• There are two type of hearing bone design

1)Horizontal herring bone twill. 2)Vertical herring bone twill.

Horizontal herring bone twill:

• When herring bone twill is created by extending the basic twill in warp direction, horizontal herring bone result in

Vertical herring bone twill:

• When hearing bone twill is created by extending the basic twill in weft direction, herring bone result in

Herringbone twill

Diamond Design:

• It is a derivatives of twill weave. It constructed on the bans of zigzag twill principle. It is obtain by combining a horizontal and vertical zigzag twill.

• So here in the repeat the number of both warp and weft thread are double then that in basic twill.

Diamond design geometrical about there vertical and horizontal axis. In this weave pointed draft is obtained

Diaper Design:

• Diaper Design: • This derivative of twill weave is created on the

basis herring bone principle. This design is constructed by combining horizontal and vertical hearing bone twill.
