Textiles – an introduction
Textile is a type of material composed of natural or synthetic fibers. Types of textiles include animal-based material such as wool or silk, plant-based material such as linen and cotton, and synthetic material such as polyester and rayon. Textiles are often associated with the production of clothing.
What are Textiles?
The word “textile” was originally used to define a woven fabric and the processes involved in weaving.Textile refers to any material made of interlacing fibers or Yarns. The yarn is produced by spinning raw fibers of wool, flax, cotton, or other material to produce long strands.Textiles are formed by weaving, knitting, crocheting, knotting, or pressing fibers together (felt).
The production of textiles is a craft whose speed and scale of production has been altered almost beyond recognition by industrialization and the introduction of modern manufacturing techniques. However, for the main types of textiles, plain weave, twill, or satin weave, there is little difference between the ancient and modern methods.
Over the years the term has taken on broad connotations, including the following:
- Staple filaments and fibers for use in yarns or preparation of woven, knitted, tufted or nonwoven fabrics,
- Yarns made from natural or man-made fibers,
- Fabrics and other products made from fibers or from yarns, and
- Apparel or other articles fabricated from the above which retain the flexibility and drape of the original fabrics.

The broad definition of textiles will generally cover all of the products produced by the textile industry intended for intermediate structures or final products.
Textile fabrics are planar structures produced by interlacing or entangling yarns or fibers in some manner. In turn, textile yarns are continuous strands made up of textile fibers, the basic physical structures or elements which makes up textile products. Each individual fiber is made up of millions of individual long molecular chains of the discrete chemical structure.
The arrangement and orientation of these molecules within the individual fiber, as well as the gross cross section and shape of the fiber (morphology), will affect fiber properties, but by far the molecular structure of the long molecular chains which make up the fiber will determine its basic physical and chemical nature.
Usually, the polymeric molecular chains found in fibers have a definite chemical sequence which repeats itself along the length of the molecule. The total number of units which repeat themselves in a chain (n) varies from a few units to several hundred and is referred to as the degree of polymerization (DP) for molecules within that fiber.
