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
