The types of optical fibers depend on the refractive index, materials used, and mode of propagation of light. Fibres from such sources are called natural fibres. XMnj���AC2�a�S�L�ilbbP.�[ Individual muscle fibres are wrapped with fascia and then further bound together by more fascia into bundles called fascicules. They have strong inter-molecules forces between the chains giving them less elasticity and high tensile strength.

Flax, hemp, jute, and ramie are bast fibres, occurring in the inner bast tissue of certain plant stems and made up of overlapping cells. The fibres obtained from plants and animals are called natural fibres. For example: paper, wood, chalk, cotton, plastic, rubber ,cardboard etc. CLASSIFICATION OF FIBRES The history of fibres is as old as human civilization. 0000064459 00000 n Fibres can be divided into natural fibres and man-made or chemical fibres. But nowadays, synthetic fibres are largely used for clothing and other purposes. 0000001411 00000 n An example of a commonly used natural fiber is cotton. Examples of Natural Fibres. Synthetic fibres are made by man with the help of chemicals eg.- nylon and rayon. Fibres can be either natural or artificial.

Hence, you can classify fibres into two groups. When you consume dietary fiber, most of it passes through the intestines and is not digested. Wool: Wool is a natural textile fibre obtained from sheep, goats and camels. There are several types of fiber. Carbohydrates, together with lipids, proteins and nucleic acids, are one of the four major classes of biologically essential organic molecules found in all living organisms. thousand years, the usage of fibre was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. These are called man- made fibres. 0000067431 00000 n - jute and silk. Classification of Nerve Fiber: Based on the presence or absence of myelin sheath, they are classified into myelinated or non-myelinated nerve fibers. Know how cotton, wool and silk are formed. There are different types of textile fibers used in the apparels and also the types and numbering of yarns.Therefore it is necessary to learn the different methods to identify different textile fibers. See the following box. Role of Calcium in Nerve Function. animal: silk,wool.. mineral: gold,silver.. 2. Hope it helped you. What are Synthetic Fibres and give some Examples. Flax is considered to be the oldest and the most used natural fibre since ancient times. Usually, these dates will end in tentative plans for a second one. 0000000840 00000 n Selecting a suitable material base upon the condition of operation and machinability and many other factors is also a big task.

Fibers can occur naturally as plant and animal fibers, but they can also be man-made. Sb soo lahe h kya ?? 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. ��R�j�����-�/Q Fibres from such sources are called natural fibres. 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. It passes through the body undigested, keeping your digestive system clean and healthy, easing bowel movements, and flushing cholesterol and harmful carcinogens out of the body. Explanation: Natural fibres are obtained from plants and animals eg. 0000001236 00000 n Some examples are cotton, silk, wool etc. These bundles of fascicles are then grouped together to form skeletal muscle which is coated by more fascia. The knowledge of identifying the textile fibers helps a producer of garments to identify the type of fiber and the care to be taken in maintaining the fabrics made of a particular type of fiber. This is an important factor for labeling of the garments… plants and animals. A fiber is the smallest unit of a textile material that has a length many times greater than its diameter. 2.2 Man made Fibers.
