Method of
Presentation of Draft :
Draft is
giving following three information about fabric :
·
Order
of passing the end through heald frame.
·
No.
of heald frame required.
· How
many ends are repeat.
Following
method use to represent the draft :
1. By using number
2. By using vertical and horizontal line
3. By using a graph paper
1. By using Number : here we discussing about popular drafting system use
in
designing.
Draft is
represent by the numerical number.
Exp. :
i.
Straight Draft
1
2 3 4
No.
of ends = 4
No. of Heald Frame
Required = 4
ii.
Skip Draft
1 3 2 4
No. of ends = 4
No. of Heald Frame
Required = 4
iii.
Pointed Draft
1 2
3 4 3
2
No. of ends = 6
No. of Heald Frame
Required = 4
iv.
Broken Draft
1 2 3 4 1 2 3 4 2 1 4 3 2 1 4 3
No. of ends = 16
No. of Heald Frame
Required = 4
2. By using vertical and horizontal Line
:- In this representation system, draft
is represent by a line . in which vertical line represent the ends (E) and horizontal line represent the Heald(H).
I.
Straight Draft
1
2 3 4
E
= 4
H = 4
II.
Skip Draft
1 3 2 4
E = 4
H = 4
III.
Pointed Draft
1 2
3 4 3
2
E = 6
H = 4
IV.
Broken Draft
1 2 3 4 1 2 3 4 2 1 4 3 2 1 4 3
E = 16
H = 4
3. By Using Graph Paper:
I.
Straight Draft
1
2 3 4
E
= 4
H = 4
II.
Skip Draft
1 3 2 4
E = 4
H = 4
III.
Pointed Draft
1 2
3 4 3
2
E = 6
H = 4
IV.
Broken Draft
1 2 3
4 1 2
3 4 2
1 4 3
2 1 4
3
E = 16
H = 4
