Differentiate the following
Sedimentation and Decantation
2. Natural and Synthetic fibres
Answers
Answer:
Sedimentation is a process of settling down of the heavier particles present in a liquid mixture.
For example, in a mixture of sand and water, sand settles down at the bottom. This is sedimentation.
Decantation is the process of separating liquid components of a mixture while the solid component has settled at the bottom as sediments, that is, transferring a liquid from another container.
When water is separated from the mixture of sand and water, it is decantation.
Explanation:
Natural fibres:
Fibres produced by plants or animals are called natural fibres. Best examples of plant fibres are: linen and cotton. Examples of animal fibres are: wool and silk. They have natural color. Incase coloring is required then dying is very easy. Usually natural fabrics are comfortable to wear. It is environmental friendly. On burning it turns into ash. Limited use of these fibres when compared to synthetic fibres.
Synthetic fibres:
Man made fibres created in laboratories are called synthetic fibres. Examples of synthetic fibres are acrylic, nylon and polyester. Colors can be added as per required. Coloring is difficult. Theses fabrics are not comfortable to wear when compared to natural fibres. It is not environmental friendly because some fibres like polypropylene is harmful. On burning it melts and gives out chemical smell. These fibres are more durable than natural fibres.
Explanation:
1. Sedimentation is a process of settling down of the heavier particles present in a liquid mixture whereas Decantation is the process of separating liquid components of a mixture while the solid component has settled at the bottom as sediments, that is, transferring a liquid from another container.
2. 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.
