Identify yarns made from different fibres by breaking test
Identify yarns made from different fibres by breaking test – Collect samples of
fabrics made from different fibres. Take out yarns from each of these and keep each
one separately. One by one, hold each yarn in both the hands and break it. You will
observe the following:
1. cotton - breaks easily, has brush like tips and slightly curled fibres.
2. flex - stronger then cotton, needs more strength to break.
3. jute - yarn breaks easily.
4. wool - yarn stretches and breaks with a brush like tip.
6. silk - yarn breaks with a jerk.
7. rayon - yarn breaks easily and does not have brush like tip.
8. synthetics - yarn stretches and does not break easily.
