TYPESOFFABRIC

1. Woven Fabric. (Interlacement)

2. Knitted. (Inter looping)3. Non woven. (Fibre sheet, interlining)

4. Braid. (Interwining)


3/19

WOVENFABRIC:

Weaving is the intersection of two sets of straightyarns, warp and weft, which cross and interlaceat right angles to each other. The lengthwiseyarns are known as warp yarns and widthwiseyarns are known as weft or filling yarns and the

fabric produced is known as woven fabric.

Example:Plain, Twill, Shatin

Application: Gavadin, Denim,, Poplin etc


4/19

KNITTEDFABRIC:

Knitting is a process of manufacturing a fabric

by the intermeshing of loops of yarns and the

fabric produced this is known as knitted fabric.

Example:Single Jersey, Double Jersey

Application: T-Shirt, Polo- Shirt, Stocking etc.


5/19

NONWOVEN:

Non wovens are a sheet, web or bat of naturaland manmade fibres or filaments, excludingpaper, that have been covered into yarns andthat are bonded to each other by any of severalmeans web formation, web bonding.

Example:Fusible (interlining), Coated fabrics,Film fabrics.

Application:Diapers, sanitary napkin, industrialmusk, bandages etc.


6/19

BRAID:

Braid is one kind of narrow fabric. This kind offabric is formed on braiding m/c by interlacingthree or more strands of yarn. The process ofinterlacing three or more threads in such a way

that they cross one another is laid together indiagonal formation.

Example:Fire brigade water pipe, shoe lace,cloth lines, electric wire, ropes etc.

METHODSOFFABRICREPRESENTATION:

The unit of woven fabric is the point of intersection of awarp end and a weft pick. The interlacing is of two possiblekinds-

A. Warp over weft interlacing.

B. Warp under weft interlacing.

In this interlacing, the warp thread is raised to produceinterlacing.

In this interlacing, the warp yarn is lowered to produceinterlacing.

FEATUREOFDESIGN:

The vertical lines/ space is to represented a warp

end

The Horizontal space is to represent to a weft pick.

Each square indicates an intersection of an endand a pick.

Represents warp up over weft. And represents weft up over warp.

There are two and only two possibilities of eachcrossing, either the end passes over the pick or thepick passes over the end.

Only one repeat should be shown on design paper.

Symbols indicate repeat unit.

# Represents starting point.

Some Important Terms or Factors

Formula Number:

Formula number is notation diagram which

represent the warp and weft interlacing point. Thesystem of expressing the fabric representation is

called Formula number.

The warp floats coming up are put above the

fraction line and the weft floats going down are put

above the fraction line and the weft floats goingdown are put under the fraction line.
