Woven fabric consumption formula for textile eng

How can measurement  Apparel Merchandising, for Fashion design.
Before calculate the woven fabric consumption, you must need the followings information as mentioned step by step-:

1) Measurement chart with technical spec.
2) Style Description.
3) Fabric Description.
4) Fabrics width/weight.
5) Washing shrinkage if any.
6)

This formula is as under :
Formula = Length  X Width  / Fab width X Fab Unit


Here,
Length = length of the specific parts + allowance

Width  = width  of the specific parts + allowance

Fab width = Fabric width ( after considering the shrinkage
                    allowance).
                   Say, fabric width is 45" & the shrinkage
                   allowance is 1", Then the Fabric width will
                   be (45"-1") = 44" in the formula.

Fab unit = Fabric calculation unit, here it will be 36 because
                we are going to calculate the consumption in
                Yards.


Now we will calculate the consumption of a Shirt (front part)

Center front length  = 32"+1" (Sewing allowance) = 33"
Width (Chest)        = 24" + 1" (Sewing allowance) + 3"
                                 Pleat.W (1.5X2)  = 28"


= Length  X Width  / Fab width X Fab Unit
= 33" X 28" /  44" X 36"
= 924" / 1584"
= 0.5833333

= 0.59 Yards. (for front part)

AutoCAD for Apparel Industry For Textile engineer

What is auto cad? 
1. A Computer-Aided Design & Drafting (CADD) tool designs for interior design, architecture and engineering.
2. More and more clothing manufacturers are using AutoCAD as it is affordable, running on PCs and is a multipurpose tool.
Auto cad in apparel industry ?
AutoCAD is a vector-based drawing, all the drawing is based on X, Y co-ordinate (2D or 3D).
It is highly accuracy, ability to work in full scale (zoom in/out), rework design ideas and make changes instantly.
 Ability to make complex calculations. (after all, all design in AutoCAD is based on mathematics formula)

  Application Area? 
 Sketch: It is a conceptual process, art work for design purpose.
 Pattern making: A technical drawing with measurements, seam allowance for garment making
 Grading Patterns: A modification of pattern making for different sizes based on grading rules
 Making Markers: A process to arrange all fabric pieces (front/back/sleeve) with different sizes (S/M/L/XL) on cutting table for cutting

FAQ
Discuss how AutoCAD can be applied in these four areas (sketching, pattern making, grading and marker making) in Clothing Production


Full Size Sketch/Design can be made by AutoCAD

                                Mirror image is basic tool from AutoCAD for CAD drawing


 Modification of sleeve based on AutoCAD


 All drawing in AutoCAD is based on mathematics. All cut piece areas
Are calculated immediately and maximum fabric utilization


 Marker Making process.
First arrange the large piece on the cutting table.
Second arrange the small piece to fill in the gap


Product Specification (trouser)
Based on AutoCAD drawing


Guess the fabric utilization based on circles in this drawing?

AutoCAD calculates the area of each circle and subtract it from the total area of cutting table.


 The utilization in this example is 78%
