You can specify conditions of storing and accessing cookies in your browser. Traces of natural fibres have been located to ancient civilizations all over the gobe. Wool: Wool is a natural textile fibre obtained from sheep, goats and camels. For example: paper, wood, chalk, cotton, plastic, rubber ,cardboard etc. 0000002341 00000 n They have strong inter-molecules forces between the chains giving them less elasticity and high tensile strength. Hence, you can classify fibres into two groups. There are several types of fiber. %PDF-1.3 %���� The classification based on the refractive index is as follows: Step Index Fibers: It consists of a core surrounded by the cladding, which has a single uniform index of refraction. Cephalosporins: For Ex: cotton, wool ,Silk ,flax, jute. But nowadays, synthetic fibres are largely used for clothing and other purposes. Fiber, also known as roughage, is the part of plant-based foods (grains, fruits, vegetables, nuts, and beans) that the body cant break down. These bundles of fascicles are then grouped together to form skeletal muscle which is coated by more fascia. For many thousand years, the usage of fiber was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. Short fibres - Staple fibre Long fibres - Filament fibre Fibres can also be classifed on the basis of their origin. Animal fibres: These are the fibres that are obtained from animals. Most Americans do not consume nearly enough fiber in their diet, so while it is wise to aim for this goal, any increase in fiber in your diet can be beneficial. Role of Calcium in Nerve Function. Cotton fibers made from the cotton plant, for example, produce fabrics that are light in weight, soft in texture, and which can be made in various sizes and colors. The intermolecular forces may be hydrogen bonds or dipole-dipole interaction. 2.2 Man made Fibers. Give two example of each.
