Analysis of woven fabric(Diamond)

Experiment name: Analysis of woven fabric(Diamond).
Object:
1.To sketch the structure of fabric.
2.To know about the raw material of fabric.
3.To know about different specifications of fabric.

Sample: 
 
Apparatus:
1. Counting glass,
2. Needle,
3. Beesleys balance,
4. Twist tester,
5. GSM cutter,
6. Graph paper.

Analysis:
1. Weave plan: In graph the gaps between the lines are considered according to X axis as weft threads and according to Y axis as warp threads. The up threads are indicated by filling up the gaps and down threads without filling up the gaps.

2. Drafting plan: According to British system drafting plan is drawn at the top of weave plan. Here pointed draft is used to draft the plan.

3. Lifting plan: The lifting plan is drawn at the right side of the weave plan.

4. Face side and backside: The face and backside can be easily understood.

5. Direction of warp and weft: Direction of both warp and weft are indicated by arrow marks by the side of the sample.

6. Raw material: Both warp and weft yarns are cotton.

7. Thread density:

10. Direction of twist: Both warp and weft yarns are ‘Z’ twisted.
11. Design of fabric: The formula number of this fabric is .

12. GSM calculation: We take one square inch fabric sample and find its weight 0.1116 gm.

We know 1 inch = 2.54 cm i.e. 0.0254 m. So, 1 sq. inch = 0.02542 sq. m.

Now, 0.02542 sq. m sample wt. = 0.1116 gm.

1 sq. m sample wt. = 173 gm.

Therefore GSM of fabric is 267 gm/meter2.


13. Repeat size: The repeat size of this fabric is 18´18.


14. Type of loom: Tappet loom is used to produce this fabric.


End Use:  
This type of fabric is used for making towel, bedsheet, pillow cover, table cloth and so on.

Conclusion: 
Analysis of fabric structure is very essential to know about the fabric. Because it gives all kinds of information about the fabric that is needed to reproduce or to change structure or design of fabric. By this practical I learn how to analyse primarily a simple plain structure of woven fabric.
