Plain weave report

Plain weave pattern

Twill weave

Twill weave report

Twill weave pattern

This pattern can be described in the formula:

$T \frac{1}{} \frac{}{2} Z$

Where:

T = Twill
Fractional line = warp rise above and weft rise below
Z = twill direction

Satin weave

Satin weave has just one weave point for each warp in the weave report. The points of interlacing should be scattered over the weave and cannot be placed side by side.

Satin weave report

A weft-faced satin with the report 5x5 and step number 3

Satin weave pattern

This pattern can be described in the formula:

$S \frac{1}{} \frac{}{4} (3)$

Where:

S = satin
Fractional line = warp rise above and weft rise below
(x) = step number
The step number cannot be 1 or a number equally divisible by the report number.

Examples

The possible step numbers for a report 5*5: 2 and 3
The possible step numbers for a report 7*7: 2, 3, 4 and 5
The possible step numbers for a report 8*8: 3 and 5

Three steps are required to draw a satin pattern:

Adding the numbers in the formula to get the report. In the figure: 1 + 4 = 5 which means the report is 5 * 5 squares or threads.
Beginning from the left corner with a filled square for a weft-faced satin or an empty square for a warp-faced satin. In this figure it is a weft-faced satin.
Count the number of squares equaling the step number and step to the right. Fill it for a weft-faced satin or keep it empty for a warp-faced satin.

Exercise

Match the formula for each weave pattern below. Drag the formula above the corresponding image.

$S \frac{1}{} \frac{}{4} (3)$

$S \frac{1}{} \frac{}{4} (2)$

$S \frac{}{1} \frac{4}{} (3)$

$S \frac{}{1} \frac{4}{} (2)$
