Question

describe the activity the activity in detais to compare the strength of synthetic fibres with those of natural fibres and also give diagram in support of your answer. pls answer in detail ​

Answer 1

Natural vs. Synthetic Fibers: What’s the Difference?




All fabrics can be characterized as either natural or synthetic fibers (or a blend of the two). Both types have pros and cons; natural fibers come from plants and animals, while synthetic fibers are made from chemical compounds, and each is valued in the textile industry for different reasons.

What Are Natural Fibers?

Natural fibers are fibers that are made out of natural materials that come from plants, animals, or minerals. The raw, natural materials are spun into threads and yarns that are then woven or knit into natural fabrics. There are two general categories of natural fibers: animal-based or plant-based. Animal-based natural fibers include silk and wool, while plant-based natural fibers include cotton, linen, and jute.

Answer 2

Synthetic fibres are stronger because they are made by plastics and other materials.Nylon is an example of synthetic fibre which is used for making parachutes and ropes for rock climbing.Activity -

Activity -Take threads of cotton and nylon(synthetic fibres) of about same length and thickness.. Hang cotton, thread from a stand. Attach a pan at the other end of the thread.Add weights, one by one, to the pan until the thread breaks (see fig.) note the total weight required to break the cotton thread. This gives a measure of the tensile strength of the thread. Repeat the same with nylon thread.

CONCLUSION

Much more weight is required to break the nylon thread showing that nylon thread has a grater strength that the cotton thread.
