## SATIN and SATEEN WEAVES:

Satin is a warp faced rearranged twill and sateen is a rearranged weft faced twill. Thus satin is the reverse side of sateen weaves. These weaves form an important category of weaves. They are used in combination with other weaves, particularly in case of ornamented fabrics. The striking feature of these weaves is their bright appearance and smooth feel.

#### The basic characteristic of satin/sateen weaves are :

- They are either warp or weft faced weaves.
- Have no prominent weave structures.
- Only one binding point in each end or pick
- No continuous twill lines
- Have poor seam strength due to thread mobility
- More thread density is possible in warp and weft
- More mass per unit area is possible
- Have less binding points and more float lengths
- Use of move numbers (intervals of selection) is necessary to construct these weaves.

In the construction of satin/sateen weaves, the stitching points of warp or weft for a given repeat size is done by the use of move numbers or stitch or float numbers. The move numbers are selected according to the repeat size of the weave.

In choosing move numbers for the construction of satin/sateen weaves, the following rules are to be adopted:

- The move number should not be equal to the repeat of the weave
- It should not be one less than the repeat size
- It should not be a factor of the repeat size, and
- It should not be a multiple of the factor .

The designs of some satin and sateen weaves are shown in Figs.

Regular and Irregular satin weaves |

A, B and C show the different types of irregular satins and Figs. D and E show the designs of regular satin. Fig. A shows a 4 end irregular satin constructed by using a step number of 1, while Fig. B show the same satin constructed using step number of 2. Fig. D shows a 5 end regular satin constructed with a step number of 3 and Fig. E shows an 8 end regular satin constructed with a

step number of 3. Fig. F and G shows the corresponding interlacings of designs D and A respectively.

Regular and irregular sateen weaves |

Figs.A, B and C show the design of irregular sateen weaves and Figs. D and E show regular sateen design. Fig. A shows a 4 end irregular sateen constructed with the step number of 1 and Fig. B shows the same design using the step number f 2. Fig. C shows a 6 end irregular sateen. Fig. D and E show the designs of a regular 5 end and 8 end sateen constructed with step number of 3. Fig. F and G show the interlacings of design D and A respectively. The following table shows the intervals of selection for the construction of satin weaves on five, and seven to twenty two threads. Instead of the numbers given, their reciprocals may be taken. Where two intervals are given, each of these or their reciprocals will produce similar results. Where more than two intervals are given, the number of numbers shown in heavy type (or their reciprocals) will give the most perfect distribution of intersections.

## STRIPE and CHECK EFFECT ON SATIN/ SATEEN WEAVES:

By a combination of suitable identical satin-sateen designs, stripe and check effects can be produced as shown in Figs.

Satin-sateen stripes |

Satin-sateen checks |

Fig. shows a satin-sateen stripe design constructed on 8 ends in a repeat and Fig. shows a satin- sateen check design constructed on 5 ends in a repeat.
