Questions and Answers

How does the direction of yarn twist affect the prominence of twill patterns?

When the direction of yarn twist is the same as the twill direction, prominence is reduced; when opposite, prominence increases.

What are some advantages of using twill weaves in fabrics?

Twill weaves offer interesting surface textures, better wrinkle recovery, and the ability to achieve high counts for durability.

Can you list a few applications where twill weaves are commonly utilized?

Twill weaves are used in drill cloth, khaki uniforms, denim cloth, jeans, and soft furnishings.

What distinguishes satin weaves from sateen weaves?

Satin is a warp-faced weave, whereas sateen is weft-faced, making warp prominent in satin and weft in sateen. Signup and view all the answers

Study Notes

Plain Weaves

Also known as calico or tabby weave
Simplest weave with a repeat size of 2
Characteristics:
- No right or wrong side
- No lengthwise or crosswise stretch
- Less absorbent than other weaves
- Easy to crease
- Doesn't fray easily
- Versatile
- Tightest weave structure
- Strong
- Durable
Method of representation:
- Threads interlace in alternate order (first warp thread overlaps the first weft thread,and passes under the second weft thread, the second warp thread passes under the first weft thread and overlaps the second one,and so on).
Applications:
- Shirting
- Suiting
- Outer garments
- Sheer fabrics
- Blouses
- Dresses
Textural Stability:
- Firmness of a woven fabric depends on the frequency of interlacing between warp and weft threads.
- More intersections mean a firmer fabric.

Twill Weaves

Second basic weave
Distinguishing feature: pronounced diagonal lines along the fabric width
Diagonal lines repeated regularly, usually running from left to right and right to left at a 45 degree angle.
Twill weaves vary in their angle from a low slope to a very steep slope.
A twill warp end must float over a minimum of two weft picks and under one weft pick; otherwise, it will still be a plain weave.
Classification:
- Right hand twill (diagonals run from right to left, called Z-twill), left hand twill (diagonals run from left to right, called S-twill)
Method of representation: fractions (e.g., 2/1, 3/1, 3/2) - numerator is the number of weft threads a warp thread overlaps; denominator is the number of weft threads a warp thread underlaps within the repeat, the sum of the fractions = repeat size
Firmness: depends upon number of intersections per unit area
Types:
- Balanced twill
- Irregular cross twill
Applications:
- Drill cloth
- Khaki uniforms
- Denim cloth
- Blankets
- Shirting
- Hangings
- Soft furnishings
- Jeans
Characteristics:
- Twill weaves may vary in angle
Additional Notes:
- Variations from low slope to very steep slope are possible

Satin and Sateen Weaves

Satin is a warp-faced rearranged twill and Sateen is a weft-faced rearranged twill
Warp is more prominent in Satin, and weft in Sateen
Common use: as part of ornamented fabrics
Striking characteristic: bright appearance and smooth feel, due to fine count filament yarns; few interlacing points, which provide long floats
Characteristics:
- Either warp or weft faced
- No prominent weave structures
- One binding point in each end or pick
- No continuous twill lines
- Poor seam strength due to thread mobility
- Possible to have more thread density in warp and weft, and greater mass per unit area
- Having less binding points and more float lengths
- Using move numbers is necessary to construct these weaves
Method of representation: Fractions (e.g., 4/1, 1/4) - numerator = number of weft threads a warp thread overlaps, and denominator= number of weft threads skipped by warp thread in a repeat
Applications:
- Denim.
- Fabric interlinings.
- Ribbons.
- Dress materials (lustrous).
- Children's clothing materials.

Plain Weave Derivatives

Warp Rib
Weft Rib
Matt

Twill Weave Derivatives

Pointed Twill
Herringbone Twill
Combined Twill
Broken Twill
Elongated Twill

Honeycomb Weaves

Threads form ridges and hollows, giving a cell-like appearance
Warp and weft threads float freely on either fabric side
Fabric is highly moisture absorbent
Common uses: towels, bedcovers, quilts
Types:
- Ordinary Honeycombs (Single Ridge, Double Ridge)
- Brighton's Honeycomb

Mockleno Weaves

Imitation of leno or gauze weaves
Similar perforated effects to leno or gauze weaving
Types:
- Simple Mockleno
- Spotted Mockleno

Huckaback Weaves

Coarse absorbent linen or cotton fabric for towels and glass cloth
Structure: similar to a checkerboard
Features: moisture-absorbing, firm, and hard-wearing

Diamond & Diaper Weaves

Further development of twill weave structures
Diamond weaves: combining right and left hand twills in four divided portions
Diaper weaves: combining right and left hand twills using herringbone junctions

Crepe Fabrics

Fabrics: characterized by roughness and irregularity
Production methods:
- Using crepe yarns (hard, high twist for irregular appearance)
- Applying special finishes (e.g., chemical/mechanical shrinkage to give crinkled/abraded effect)
- Using special woven structures (e.g., combining weaves in specific ways)
