How does water affect the mechanical behavior of natural fibers?
The presence of water plays a crucial role in the mechanical behavior of natural fibers. Hydrated, biopolymers generally have enhanced ductility and toughness. Water plays the role of a plasticizer, a small molecule easing passage of polymer chains and in doing so increasing ductility and toughness. When using natural fibers in applications outside of their native use, the original level of hydration must be taken into account. For example when hydrated, the Young’s Modulus of collagen decreases from 3.26 to 0.6 GPa and becomes both more ductile and tougher. Additionally the density of collagen decreases from 1.34 to 1.18 g/cm^3.

Natural fibre, any hair like raw material directly obtainable from an animal, vegetable, or mineral source and convertible into nonwoven fabrics such as felt or paper or , after spinning into yar ns, into woven cloth. A natural fibre may be further defined as an agglomeration of cells in which the diameter is negligible in comparison with the length. Although nature abounds in fibrous materials, especially cellulosic types such as cotton, wood, grains, and straw, only a small number can be used for textile products or other industrial purposes. Apart from economic considerations, the usefulness of a fibre for commercial purposes is determined by such properties as length, strength, pliability, elasticity, abrasion resistance, absorbency, and various surface properties. Most textile fibres are slender, flexible, and relatively strong. They are elastic in that they stretch when put under tension and then partially or completely return to their original length when the tension is removed.

How do silkworms produce silk?
The cultivation of silkworms for the purpose of producing silk is called sericulture. The best raw silk is obtained from the species of moth called Bombyx Mori. Breeding of silkworm occurs once in a year but under scientific conditions, they may be hatched three times a year. Larvae of about 3mm are hatched from the eggs. For about 20 to 30 days they are carefully nurtured and are fed five times a day on chopped mulberry leaves. In the meantime, the larvae charge their skin for four times and are formed into caterpillar of about 9cm long. Now they are ready to spin cocoon for which racks, clusters of twigs or straw are provided.
How is cotton assessed?
The assessment is based on (1) the staple length, (2) the colour and (3) the amount of impurity in the cotton. The classer works usually by a hand-examination of the cotton. Staple length is judged by taking a sample and pulling it to display a filmy web of fibre.

What are the benefits of natural fibers?
Benefits of Natural Fibers For Textiles 1 The majority of natural fibers are bio-degradable and fully recyclable. 2 They have natural anti-bacterial properties, resist mildew and block UV radiation. 3 Textiles such as linen, silk and cotton are naturally hypoallergenic, making them ideal for sensitive skin or those prone to allergies. Newborn and baby skin benefit greatly from using these fabrics. 4 Natural fibers are breathable and heat responsive while also great insulators. Fabrics like wool, cashmere, silk and bamboo traps air between the micro-holes of the fabrics. This trapped air is then used as an insulator to generate warmth in the winter and coolness in the summer. 5 Some fibers can be organically grown and although it might be more expensive to produce and purchase, it ensures that no harmful pesticides and chemicals are used in it’s production. 6 The high absorption qualities in natural fibers are a very big plus. The moisture wicking abilities allow ventilation through the fabric, which draws dampness away from the skin, leaving you feeling dry. This is particularly important during the hot months when fabrics such as cotton and linen will help keep you cool and comfortable.

Overview
Animal fibers
Animal fibers generally comprise proteins such as collagen, keratin and fibroin; examples include silk, sinew, wool, catgut, angora, mohair and alpaca.
• Animal hair (wool or hairs): Fiber or wool taken from animals or hairy mammals. e.g. sheep's wool, goat hair (cashmere, mohair), alpaca hair, horse hair, etc.
• Silk fiber: Fiber secreted by glands (often located near the mouth) of insects during the preparation of cocoons.
Chitin
Chitin is the second most abundant natural polymer in the world, with collagen being the first. It is a “linear polysaccharide of β-(1-4)-2-acetamido-2-deoxy-D-glucose”. Chitin is highly crystalline and is usually composed of chains organized in a β sheet. Due to its high crystallinity and chemical structure, it is insoluble in many solvents. It also has a low toxicity in the body and is inert in t…
