Questions and Answers

What distinguishes regular Weft Sateen from irregular Weft Sateen?

Regular Weft Sateen has a definite move number throughout the repeat, while irregular Weft Sateen lacks a definite move number.

Provide an example of a standard irregular satin and a standard irregular sateen.

Examples include 3/1 (4 – End) Satin for standard irregular satin and 1/3 (4 – End) Sateen for standard irregular sateen.

What is the significance of the 'end' in the fabric construction notation like 5/1 (6 – End)?

The 'end' indicates the number of warp threads per repeat used in the fabric's construction.

Study Notes

Plain Weaves

Plain weave is also known as calico or tabby weave.
It is the simplest weave with a repeat size of 2.
This weave has a maximum number of binding points.
It has no right or wrong side and doesn't have lengthwise or crosswise stretch.
Plain weave doesn't fray easily.
It creases easily.
Plain weave absorbs less than other weaves.
It is versatile.
Plain weave is the tightest weave structure.
It is strong and hard-wearing.
It is also durable.
The threads alternate between passing over and under the other set of threads.

Twill Weaves

A twill weave is a basic weave design.
The main feature of a twill weave is the presence of pronounced diagonal lines.
In regular twill, the diagonal line usually runs from left to right, forming a distinct pattern.
The angle of diagonal lines is at 45 Degrees.
Twill weaves show variation in angle, from a low 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 appear to be a plain weave.
Twill weaves can be expressed as fractions (e.g. 3/1).
The numerator of the fraction represents the number of warp threads that overlap.
The denominator represents the number of warp threads that are underneath.
The sum of the numerator and denominator of this fraction represents the repeat of the twill.
Examples of twill include drill cloth, khaki uniforms, denim cloth, blankets, shirting, hangings, and soft furnishings.
Twill weaves have good textural stability due to a high number of intersections per unit area.
There are two main types of twills: balanced twill and irregular cross twill.

Satin and Sateen Weaves

Satin and sateen are warp and weft faced rearranged variations of twills.
Satin, warp faced, has warp threads more prominent.
Sateen, weft faced, has weft threads more prominent.
Satin and Sateen have no prominent weave structures.
Both weaves have only one binding point in each end or pick.
. They have poor seam strength due to thread mobility.
Satin and Sateen fabrics have high thread densities.
These fabrics have high mass per unit area.
They have more float lengths.
Move numbers(Intervals of selection) are required during construction.
Important application is in combination with other weaves to create ornamented fabrics

Plain Weave Derivatives

Warp rib, weft rib, mock rib, simple matt, and fancy matt, dimity are derivatives of plain weave.
Warp ribs produce horizontal strips.
Weft ribs produce vertical strips.
Mock ribs and Matt weaves are based on plain weave.
Dimity weaves are a combination of plain weave and its derivatives.

Twill Weave Derivatives

Pointed twill, herringbone twill, combined twill, broken twill, transposed twill, elongated twill, and curved twill are all derived from the basic twill weave.

Satin & Sateen Weaves Derivatives

Extended satin & sateen, satin & sateen stripe, satin & sateen check, rearranged twills, corkscrew twills, twilled hopsack.

Honeycomb Weaves

Honeycomb weaves have a cell-like appearance due to ridges and hollows.
Honeycomb fabrics are highly moisture absorbent.
Honeycomb weaves are often used for towels, bedcovers, and quilts.
Includes Ordinary Honeycombs (Single Ridge Honeycomb, Double Ridge Honeycomb, Fancy Honeycomb) and Brighton's Honeycombs

Checkerboard Weaves

Checkerboard weaves combine two different weaves to produce a patterned effect.
Common methods to create the checkerboard pattern include using basic weaves and derivatives, combining warp and weft-faced weaves, using twill weaves in opposite directions, or by combining different weaves.

Crepe Fabrics

Crepe fabrics are generally characterized by their roughness and irregularity.
They can be produced by using crepe yarns, applying special finishes, or using special woven structures.
Crepe fabrics are used for medical bandages and other specialized applications.

Huckaback Weaves

Huckaback weaves are coarse absorbent fabrics often used for towels and glass cloth.
Their structure combines plain weave and loose floats for good moisture absorption.
Classifications include Ordinary, Reversible, and Grecian Huckaback.
