Deconstruction Assignment

Year 9 Textiles and Design

Properties and Performance of Textiles

Length: 3-4 pages. Marks / value: 15% of semester mark. Date due: Week 8, Term 1 2008.

Purpose of this assignment

Students will be given an opportunity to discover how garments are made commercially. They will practise identifying pattern parts and will study the sequence of construction and manufacturing techniques.

Targeted Outcomes
5.1.1 Explains the properties and performance of a range of textile items
5.1.2 Justifies the selection of textile materials for specific end uses
5.14.1 Selects and uses appropriate technology to creatively document,communicate and present design and project work
5.6.1 Evaluates textile items to determine quality in their design and construction

Task

Students will purchase a second hand commercially made garment, deconstruct it and complete a series of activities that analyse the parts of the garment and its construction.

PLANNING SECTION

Define the Task

· Purchase a second hand commercially made garment or find one at home that is no longer needed. Do not choose an overly simple or complex garment.

· It must be made from WOVEN fabric.

· If it is a top or dress, it should have sleeves. If it is pants or a skirt, it should have a waistband.

· Carefully undo all seams and hems until the garment is in its component pieces. Don’t rip or cut.

· Fold the pieces carefully and include in the back of your assignment.

Now complete the following activities:

1. Draw the pattern pieces to scale using a ruler. Label pattern pieces with a name (eg front), cut number (eg cut 1 on the fold), and a grain line. (1/2 page) /5

2. Does the fabric have nap? Why or why not? /1

3. Draw and label each notion used to complete the garment (eg 30cm x 2cm wide elastic, thread, 26cm zipper, 4 x 1cm wide buttons, interfacing). /2

4. What type of woven fabric is it? (For example, plain weave, twill weave, satin weave.) /2

5. Unravel some of the fabric until you have some yarn. Is the yarn staple or filament? /2

6. Conduct a burn test at home and present the results in a table with the following 5 headings: /4

Near the flame Smoke In the flame Odour and ash Lit - out of the flame

7. After conducting the burn test conclude and explain what fibre or fibre blend you think your item is made from (eg cotton, wool, polyester, polyester/cotton etc)? /2

8. Draw a flow chart showing the sequence of construction. /4

9. Name 2 manufacturing techniques you noticed on the garment (eg top-stitching, hem type, seam type etc). Explain how each technique was done by using diagrams. /4

10. Name 2 properties each that the fibre and fabric construction contributed to the overall garment (eg the cotton fibre made the top cool and strong, the plain weave structure made the top strong and firm to print the design on). /4

Locate Information

You will find both textbooks available in the classroom useful for this activity, Textiles for Modern Living, Ghol & Vilensky and Textiles, Hollen and Saddler. The Library has books on sewing on the 646 shelves and textiles on the 677 shelves. A resource booklet will also be available from your teacher.

Select and Analyse

Choose sections from the information resources listed that will assist you to complete the set activities. You need to be familiar with the correct methods of setting out scale patterns, cutting out diagrams and flow charts. Ensure also that you understand and know how to use the correct textiles terms in your responses to the set questions.

Organise and Synthesise

Arrange your responses in the order listed above and clearly number them.

Create and Present

Present the assignment neatly on A4 paper, stapled and put in a plastic slip. Do not use a display folder.

Evaluate and Reflect - Marking guidelines

Advanced 33 -40 marks	• Accurately draws pattern pieces to scale, presents a highly accurate cutting out diagram and labels it appropriately. • Correctly determines nap, fabric structure, yarn type and fibre type and analyses thoroughly the properties that each contribute to the garment. • Presents a detailed flowchart for the correct sequence of manufacture and identifies and thoroughly explains 2 manufacturing techniques. • Uses a wide variety of textiles terms appropriately.
Highly Competent 25-32 marks	• Draws pattern to scale and labels it appropriately. • Correctly determines nap, fabric structure, yarn type and fibre type and presents a sound analysis of the properties that each contribute to the garment. • Presents a flowchart for the correct sequence of manufacture and identifies and explains 2 manufacturing techniques. • Uses a variety of textiles terms appropriately.
Competent 17-24 marks	• Draws pattern pieces mostly to scale and labels most parts appropriately. • Mentions nap, fabric, yarn and fibre structure; identifies and includes some explanation of some of their properties that contribute to the garment. • Creates a sequence for the manufacture of the garment and identifies 2 manufacturing techniques. • Uses a reasonable number of textiles terms appropriately.
Developing 9-16 marks	• Attempts to draw pattern pieces to scale and labels some parts appropriately. • Mentions nap, fabric, yarn and fibre structure, and identifies some of their properties that contribute to the garment. • Creates a basic sequence for the manufacture of the garment and identifies 2 manufacturing techniques. • Uses some textiles terms appropriately.
Experiencing difficulty 1- 8 marks	• Draws some patterns but not to scale, and labeling is brief. • Identifies fibre or yarn or fabric structure and some properties. • Creates a sequence for the manufacture of the garment, but not necessarily in the correct order. Manufacturing techniques are named but not explained. • Uses few correct textiles terms.
