Fabric Structure and Design Analysis

Fabric Structure and Design Analysis

# Types of Fabric:

 1. Woven Fabric. 

2. Knitted. 

3. Non woven.

 4. Braided.  


 Foundation of the woven cloth structure or variation of woven cloth structure depends on:

 The nature /type of yarn used. 

 The count or thickness of the yarns used as warp or weft. 

 Thread density of a fabric.

  Modification produced by finishing treatment. 

 Classification of woven Fabric Structure: 

Woven structures may be conveniently divided into two principal categories:

1. Simple Structure. 2. Compound Structure.

1. Simple Structure:

 The ends and the picks intersect one another at right angles and in the cloth are respectively parallel with each other There is only one series of ends and one series of picks. Example: Plain, Twill,Satin.

2. Compound Structure:

  More than one series of ends and picks are used in this structure.

  Some of threads may be responsible for the body of the fabric whilst some may be employed for ornamental purposes. 

 In the clothes, some threads may not be parallel to each other in either plane Example: Pile, Towel fabric.


 The quality or properties which we get from fabric by interlacing of warp and weft yarn; such as handle properties, shining properties, draping properties. 

Texture of woven fabric depends on- 

 Yarn (warp, weft) count 

 EPI(ends per inch), PPI(picks per inch) Yarn twist. 

 Characteristics of fibre. Interlacement. 

 Methods of Fabric Representation: 

The unit of woven fabric is the point of intersection of a warp end and a weft pick. The interlacing is of two possible kinds

A. warp over weft interlacing. 

B. warp under weft interlacing.

Feature of design: 

 The vertical lines/ space is to represented a warp end 

 The Horizontal space is to represented to a weft pick. 

 Each square indicates an intersection of an end and a pick. 

 x represents warp up over weft. And represents weft up over warp. 

 There are two and only two possibilities of each crossing, either the end passes over the pick or the pick passes over the end. 

 Only one repeat should be shown on design paper.

  Symbol indicates repeat unit.

  # Represents starting point

# Repeat Unit:

 A no. of interlacing between warp and weft yarns combined together in both directions i.e. longitudinal and horizontal, produces a unit of design is called the repeat of the weave

#Classification of Parts of a complete design for a woven fabric: 

1) Weave Plan. 2) Drafting Plan. 3) Lifting Plan. 4) Denting Plan.

1) Weave Plan:

 It represents the interlacement of warp and weft yarn. It shows the ups downs of each yarn in a fabric sample. It is drawn on the graph paper. 

2) Drafting Plan:

 The process of drawing the warp yarn into the heald eye according to the weave plan or design is called drafting and the plan by which drafting is indicated called drafting plan. It indicates the no. of heald shafts required to make a design. It is drawn on the top of the weave plan. The vertical spaces are warp and horizontal are healds.

 3) Lifting plan:

 Lifting plan defines the selection of healds to be lifted or lowered on each successive insertion of weft or pick. Lifting plan is drawn at the right side of weave plan. 

4) Denting plan: 

The process of inserting warp yarn through reed is called denting. The planning of this denting according to order is called denting plan. Normally two yarns are passed through dent.
