This document discusses diamond and diaper fabric designs. Diamonds are symmetrical about vertical and horizontal axes and can be produced using point drafting and vertical waved twills. They converge to a vertex. Diapers are symmetrical along diagonal axes and use a herringbone draft. Key differences are that diamonds use a wavy twill construction while diapers use a herringbone twill. Both designs have characteristics like being divisible into quarters and having double the warp and weft yarns of basic twills. Diamonds and diapers are used for items like towels, bedding, and tablecloths.

5. DIAMONDS
Those that are symmetrical about their vertical and horizontal axes which can be produced
with the aid of point draft and vertical waved twilled peg-plan.
DIAMOND WEAVE
Principle of Construction:
True diamond shapes converge into a vertex and for this reason most designs of this type can
be constructed economically on the point draft basis. The structure may be developed in
following two ways:
By employing a vertical waved twill or zigzag as the lifting plan in conjunction with the point
draft.

6. By indicating a diamond base and building up the design symmetrically on each side of the
centre thread.
While this represents the same twill arrange to zigzag vertically.
Two such repeats are given in each direction.
First method is most commonly employed to produce economical diamonds.

7. Lifting plan

8. Characteristics of diamond design:
1. Diamond design combines horizontal zigzag twill and vertical zigzag twill.
2. Diamond design is symmetrical on both axis.
3. Point drafting system produces diamond design.
4. No. of both warp and weft yarns are double to the basic twill in the repeat.
5. Dobby loom is generally referred because of large number of ends in the repeat.
6. It can be divided into 4 equal parts.
7. It can be divided into two equal parts along horizontal and vertical axis.
8. Diamond design is used to produce towel, bed cover, table cover, pillow cover etc.

9. DIAPERS
Those that are symmetrical about their diagonal axes, these are based
on herringbone draft and vertical waved twilled peg-plan.
Diamond is constructed on wavy twill while Diaper is constructed on herringbone twill.
DIAPERS CONSTRUCTION
This class of weave will form cut effect or dice effect with the implementation of
herringbone twill. This effect is used in ornamentation, shirting, etc.

10. Principle of Construction:
The simplest weaves of this type are produced as a further development of the herringbone twill,
which the principle of opposing a warp float on the one side of the design by a weft float on the ot
is extended in both directions, i.e. horizontally and vertically.
In this manner a design is formed in which the typical herringbone cut splits the design into four
quarters, the diagonally opposite caters being similar.
These structures are frequently employed as they are capable of forming large design repeats with
considerable economy in the number of heald to be used.

12. Characteristics of diaper design:
1. Diaper design combines horizontal herring bone and vertical herring bone.
2. Broken draft or straight draft is used to produce diaper design.
3. The repeat size of warp is equal to weft.
4. No. of both warp and weft yarns are double to the basic twill in the repeat.
5. It can be divided into two equal parts along diagonal axis.
6. Diapers from symmetry across their diagonal axis.
7. Diaper design is used to produce towel, bed cover, table cover, pillow cover many
other household fabrics.

13. Diamond weave Diaper weave
It looks like a diamond It looks like a dice checks
It can be formed by two methods
o Baseline
o Wavy twill
It can be formed by using herring
bone twill
Diamond is asymmetrical on both
vertically and horizontally. It is only diagonally similar.
This is used for dress material and
furnishing fabrics. This is used for dress materials.
This weave is produced with point
draft It is not produced with point draft.
