Question

how can you identify a natural and synthetic fibre​

Answer 1

Answer:

Fibres can be identified from very small yarn samples. Typically, 0.4 cm (1/8") or less is clipped from an exposed yarn end in good condition in an inconspicuous area. Both warp and weft yarns should be sampled because some fabrics are made of one fibre type in the warp and another in the weft.

Identification of fibres For identifying the fibres there are different methods. The first and simple method is the burn test. If you take a sample of the fibre and burn it, you can identify the fibre because of the smell and the ash. Samples of the fibre can be also identified under the microscope.

Answer:

Natural fabrics, like merino wool, cotton, cashmere, and silk, are made of fibers that are produced by animals and plants. Synthetic fabrics, like polyester, nylon and acrylic, are "man-made" fibers that are created in laboratories.
