This lab report summarizes an experiment on drafting a basic trouser pattern. The student measured their body and drafted the front and back patterns according to standard procedures. Key steps included marking waist, hip, and thigh measurements; determining crotch depth and extensions; drafting darts; and connecting points to create the trouser shape. The student concluded they gained practical knowledge on measuring for and drafting trouser patterns that will be useful for their career.
![Working Procedure:-
1. Take a pattern paper and divided it into two parts. Then draw the total
length of the trouser A to B. A to B total length is 34".
2. From A, mark out the Crotch depth point C+ 0.25" vertically. Here A-
C=9". Square out the point C to the left and right. Then take one third of
measurement from C towards A. And label this point D. Square out the
point D to the left and right. C-D= 3".
3. Mark out the back hip (C-E) and front hip (C-F) measurement from C
and label this point E&F.
Back hip=[hip/4]+.25"= [35"/4]+.25"=9"Front hip=[hip/4]-.25"=
[35"/4]-.25"=8.5"
After taking hip measurement, Connect the lines on back D-G & A-I
which is same as C-E. On the Front line D-H & A-J is same as C-F.
4. Mark the middle of the vertical lines I-E at the back and J-F at the
front and label them K & L.
5. Back Crotch extension: Taken half the back hip measurement, taken
from E to outwards and label M. E-M=4" front Crotch extension. Taken
the quarter Front hip measurement, taken from F to outwards. And label
N.F-N=2.25".
6. Mark 2" lines at Angle 450 from E. Then draw the crotch touching M,
the 2" & K. Mark 1.5" lines at Angle 450 from F. Then draw the crotch
touching N, the 1.5" & L.
7. From I, mark 0.75 inch inwards & label as O. From O, mark the back
waist 7.5"+2.25". 2" for the dart & 0.25" for the ease.](https://image.slidesharecdn.com/175035apparellab-03asadsir-210629074158/85/175035-apparel-lab-03-asad-sir-4-320.jpg)
![8. Find the midpoint & draw the 2" wide dart with a length of 3" and
connect the dart length also connect K to O with a line.
9. Raise O by 0.25", above the waist line and connect back to the waist
mark with a slant line. And connect the waist mark to the hip using
scale.
10. From J, mark the front waist measurement+1.25" horizontally and 1"
for the dart. Find the midpoint and draw in the 1" wide dart.
Front waist =[waist/4]+.25"= [31"/4]+.25"=8".
11. Then Lower J by .25" and draw a line linking J to the waist mark on
the top line.
12. Mark the knee point and square out P=[C-B/2]-1=[30/2]-1=14"
13. Mark the midpoint of M-C & C-N and connect to the bottom line.
14. And the bottom of the trouser Front side, Mark the trouser line in left
2" and right 3". Connect N to the line and also connect out seam to hem.
On the Back part,
Also connect M to hem and out seam to hem.
All the operation is done and cut the front and back part.](https://image.slidesharecdn.com/175035apparellab-03asadsir-210629074158/85/175035-apparel-lab-03-asad-sir-5-320.jpg)

- 1. Lab Report Course Code:-TE-3402 Course Title:-Apparel Manufacturing Engineering-I (Sessional) Experiment No. 03 Name:-Study on basic pattern drafting of Trouser. Submitted by Submitted to Md. Ashadujjaman Ashad Assistant Professor Department of TE Dhaka University of Engineering & Technology (DUET), Gazipur Date of Performance 28-04-2021 Date of Submission 02-06-2021 Name : ID : Year and Semester : Session : Department : Mahbubay Rabbani 175035 3/1 2018-19 Textile Engineering
- 2. Introduction:- Pattern making is an art. It is the art of manipulating and creating flat pieces of fabric to match one or more curves of the human figure. Pattern making is a bridge function between design and production. The sketch can be transformed into a garment through a pattern that explains the design clothing material form. Objectives:- To learn about pattern drafting. To learn how to create a pattern for trousers. To learn measurements for different parts of the trousers. To create a pattern according to standard body measurements. Tools and Equipment:- Measuring tape. A set square and protractor or pattern master. Hip curve. Steel rule. Pencil and eraser. Pattern paper. Required Measurements:- Waist. Hip. Upper thigh. Crotch depth. Trouser length.
- 4. Working Procedure:- 1. Take a pattern paper and divided it into two parts. Then draw the total length of the trouser A to B. A to B total length is 34". 2. From A, mark out the Crotch depth point C+ 0.25" vertically. Here A- C=9". Square out the point C to the left and right. Then take one third of measurement from C towards A. And label this point D. Square out the point D to the left and right. C-D= 3". 3. Mark out the back hip (C-E) and front hip (C-F) measurement from C and label this point E&F. Back hip=[hip/4]+.25"= [35"/4]+.25"=9"Front hip=[hip/4]-.25"= [35"/4]-.25"=8.5" After taking hip measurement, Connect the lines on back D-G & A-I which is same as C-E. On the Front line D-H & A-J is same as C-F. 4. Mark the middle of the vertical lines I-E at the back and J-F at the front and label them K & L. 5. Back Crotch extension: Taken half the back hip measurement, taken from E to outwards and label M. E-M=4" front Crotch extension. Taken the quarter Front hip measurement, taken from F to outwards. And label N.F-N=2.25". 6. Mark 2" lines at Angle 450 from E. Then draw the crotch touching M, the 2" & K. Mark 1.5" lines at Angle 450 from F. Then draw the crotch touching N, the 1.5" & L. 7. From I, mark 0.75 inch inwards & label as O. From O, mark the back waist 7.5"+2.25". 2" for the dart & 0.25" for the ease.
- 5. 8. Find the midpoint & draw the 2" wide dart with a length of 3" and connect the dart length also connect K to O with a line. 9. Raise O by 0.25", above the waist line and connect back to the waist mark with a slant line. And connect the waist mark to the hip using scale. 10. From J, mark the front waist measurement+1.25" horizontally and 1" for the dart. Find the midpoint and draw in the 1" wide dart. Front waist =[waist/4]+.25"= [31"/4]+.25"=8". 11. Then Lower J by .25" and draw a line linking J to the waist mark on the top line. 12. Mark the knee point and square out P=[C-B/2]-1=[30/2]-1=14" 13. Mark the midpoint of M-C & C-N and connect to the bottom line. 14. And the bottom of the trouser Front side, Mark the trouser line in left 2" and right 3". Connect N to the line and also connect out seam to hem. On the Back part, Also connect M to hem and out seam to hem. All the operation is done and cut the front and back part.
- 6. Conclusion:- After completing this experiment it is known how to measure body for trouser pattern. It’s also known from this experiment how to make pattern for trouser. Finally we gain practical knowledge from this experiment which will be effective for our job life.
