Natural Fibers Among the natural fibers are cellulose, the primary structural component of plants and bacterial cell walls; animal fibers such as wool and silk; and biochemical fibers. Plant fibers are composed of cellulose (see Figure 1), lignin (see Figure 2), or similar compounds; animal ...

The use of natural fibres for textile materials began before recorded history. The oldest indication of fibre use is probably the discovery offlaxandwoolfabrics at excavation sites of the Swiss lake dwellers (7th and 6th centuriesbce). Several vegetable fibres were also used by prehistoric peoples...
Construction today is a significant part of industrialculture, amanifestationof itsdiversityand complexity and a measure of its mastery of natural forces, which can produce a widely varied built environment to serve thediverseneeds of society.

Advantages of Synthetic Fibres Synthetic fibers have good elasticity. They don’t wrinkle up easily. Fabrics made from these fibres are less expensive, durable and readily available in comparison to natural fibers. Synthetic fibers can handle the heavy load without breaking. They don’t shrink. Syn...
In contrast, the purpose of the matrix in a high-performance composite is to hold the fibers together and protect them from damage from the outside environment (such as heat or moisture) and from rough handling. The matrix also transfers the load placed on a composite from one fiber bundle...
Properties of Synthetic Fibers Due to the chemical processes involved with production, the properties of synthetic fibers are objectively more complex than those of natural fibers. Synthetic fabrics are made of polymers, or chemical substances formed by two or more monomers (reactive molecules), that...
Manufacturing of Textiles Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ An example of a textile may be a woven woolen rug or a knitted acrylic garment. If an item is made of interlaced fibers, be they of natural or synthetic origin, it is considered a...
Theropod dinosaurs make up the majority of the dinosaurs that we know to have had feathers. Carnivorous dinosaurs, known as theropods, had three toes on each foot and stood erect on two legs. Proto-feathers, or thin fibers that resembled feathers and covered a dinosaur’s body in a pattern...
