Study Notes

Plain Weaves

Also known as "calico" or "tabby" weave
Simplest weave, with a repeat size of 2
Characteristics: maximum number of binding points, no right or wrong side, no lengthwise or crosswise stretch, doesn't fray easily, creases easily, less absorbent, versatile, tightest weave structure, strong, hard-wearing, and durable.

Twill Weaves

Second basic weave
Distinguishable feature: pronounced diagonal lines running along the fabric width
Diagonal lines are repeated regularly, usually running from left to right and from right to left at a 45-degree angle.
Twill weaves vary in angles from a low slope to a very steep slope.
Each warp end must float over a minimum of two weft picks and under one weft pick; otherwise, it's still a plain weave.
Right-hand twill: diagonals run from right to left (Z-twill)
Left-hand twill: diagonals run from left to right (S-twill)
Twills are expressed as fractions (e.g., 2/1, 3/1, 3/2)
Firmness depends on the number of intersections per unit area.

Types of Twill Weaves

Balanced Twill: Numerator and denominator of the fraction are equal (e.g., 2/2, 3/3)
Irregular Cross Twill: Numerator and denominator of the fraction are not equal (e.g., 3/2, 4/3)

Warp Faced Twill

Warp threads more prominent than weft threads

Weft Faced Twill

Weft threads more prominent than warp threads

Warp and Weft Faced Twill

Warp and weft threads are equally prominent

Factors Determining Twill Weave Prominence

Nature of the yarn: fineness and twist influence twill prominence. Coarse yarns with lower twist have a greater effect.
Nature of the weave: Twills with longer floats are more prominent than those with shorter floats.
Warp and weft thread densities: Higher densities yield more prominent twills.
Relative direction of twill and yarn twist: If the direction of yarn twist is the same as the twill direction, prominence is reduced; if opposite, prominence increases.

Advantages of Twill Weaves

May have face/back and up/down orientation
Interesting surface and texture
Seldom printed, better wrinkle recovery, high counts possible (more durable)

Applications of Twill Weaves

Drill cloth, khaki uniforms, denim cloth, blankets, shirting, hangings, and soft furnishings

Satin and Sateen Weaves

Satin is a warp-faced rearranged twill; Sateen is a weft-faced rearranged twill.
Satin is the reverse side of sateen.
Striking feature: bright appearance and smooth feel due to fine filament yarns
Few interlacing points = long floats, face yarns are fine and closely packed.

Satin Characteristics

Warp or weft faced weaves
No prominent weave structures
Only one binding point in each end or pick
Continuous twill lines
Have poor seam strength
Higher thread density possible in wrap and weft leading to more mass per unit area
Fewer binding points and longer float lengths
Use of move numbers (intervals of selection) is necessary

Satin/Sateen Method of Representation

In satin/sateen weaves, stitching points of warp or weft for a given repeat size are done by using move numbers or stitch or float numbers.

Satin Application

Denim, Interlining cloth, ribbons, dress materials (lustrous), children's dress materials

Regular and Irregular Satin/Sateen Weaves

Regular: has a particular move number.
Irregular: do not have a specific move number

Classification of Satin/Sateen Weaves

Warp Satin
Weft Satin
Regular Warp Satin/Irregular Warp Satin
Regular Weft Satin/Irregular Weft Satin
