Experiment name:
Analysis of woven fabric structure and specification (Diamond).
Diamond design:
Diamond design, from the point of view of construction, can be regarded as a further development of the twill weaves. Diamonds are obtained when two pointed twills are combined such that one is below the other which is tilted as shown in Fig.
Fig: Diamond design
The diamond foundation gives the student ample scope for the development of original weave effects, and in this respect the diamond frame can be made. First select an area consisting of an even number of ends and picks, and make a single diagonal line from the top left-hand corner to the bottom right-hand corner. Cross this diagonal line by a second one commencing one pick above the bottom left-hand corner or, as an alternative, on the second end from the left-hand corner and running out to the top right hand corner. These two diagonal lines produce two diamond shapes as shown and various figure effects can be inserted as desired.
The constructional procedure for a diamond is as follows:
Mark the repeat size and divide into four parts.
In the first quarter insert the basic S twill.
In the second quarter reverse the twill as that of in first quarter (Z).
Third quarter is filled with S twill.
Fourth quarter with Z twill.
In the above steps at the point of reversing it is necessary to follow the concept of wavy.
Objectives:
To sketch the structure of diamond woven fabric.
To know about the raw material of fabric.
To know about different specifications of diamond woven fabric.
Sample:
Fig: Woven fabric structure
Apparatus:
Counting glass,
Needle,
Beesleys balance,
Twist tester,
GSM cutter,
Graph paper.
Analysis of Diamond Woven Fabric Structure & Specification:
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.
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 uses:
This type of fabric is used for making towel, bedsheet, pillow cover, table cloth and so on.
Conclusion:
Analysis of diamond 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 analyze primarily a diamond structure of woven fabric.
