Fibre to Fabric Class 6 notes - Chapter 3

What are Fibres and Fabrics?

Fibers are the materials which are available in the form of thin, continuous and flexible strands spun into yarn and made into fabrics.

Fabrics are defined as a cloth material made by knitting or weaving or of threads together.

Types of Fibre

There are two types of fibers and are classified according to their origin.

  • Natural fibers: These fibers are naturally obtained from plants and animals. Cotton and jute are fibre obtained from plants. Silk and wool are fibre obtained from animals.
  • Synthetic fibre: These fibers are artificially synthesized by humans within the industry by the application of simple chemicals. Examples: Acrylic, polyester, nylon, rayon, acetate, are a few examples of Synthetic fibre.

Animal Fibers

Silk and wool are fibre obtained from animals.

Wool fibres come from sheep, camel, goat, and yak. The process involved in making animal fibers into wool follows a series of steps — Shearing, Scouring, Sorting, Cleaning, Dyeing, Straightening, Rolling and Combing.

Silk fibres are obtained from the silkworm and the process of obtaining silk from the silkworm is called sericulture. The silk thread or the yarn is obtained from the silk moth’s cocoon. The life cycle of a silkworm begins from the:

Stage 1- After mating, female silk moth lays around 200 – 300 eggs at a time.

Stage 2- The egg hatches and new silkworms arises and feed on mulberry leaves for around 30 days and move into the next stage.

Stage 3-Cocoon, a protective layer or a silky web spun is developed around the larvae, which is the size of a small cotton ball made of a single silk thread.

Stage 4- Pupa stage. A stage where silk fibres are obtained by killing the pupa and plunging the cocoon into boiling water and unwind the silk thread.

Stage 5- The last stage of a life cycle, in which the completely developed pupa changes into an adult moth. Again the life cycle begins from here.
