Explain:1. Plant and animal fibres.2. Knitting and weaving.

Fibres are used to make yarn; which in turn used to make fabric. Fibres are thread-like structures that are long, thin and flexible. These may be spun into yarns and then made into fabrics. There can be different types of fibres.

On the basis of their origin, fibres are classified as natural fibres and synthetic fibres.

1. Natural fibres- Natural fibres are the fibres that are obtained from plants, animals or mineral sources. Some of the examples are cotton, silk, wool etc.

Natural fibres can again be divided into two types -

a>plant fibres- Plant fibres are fibres that are derived from plants.

Eg. Cotton and Jute.

b>animal fibres- Animal fibres are fibres derived from animals.

Eg. Silk and Wool.

2. Synthetic fibres- Synthetic fibres are man-made fibres designed to make fabrics.

Eg. Nylon and Rayon.

Knitting

• Knitting is created with loops, or stitches, that run together for the entire project.  

• A knitter uses two knitting needles to create these loops. 

• A knitted cloth can also be created with a knitting loom. 

• The loom holds the yarns in places are the knitter moves the stitches between the loom pegs. 

• These loops form a cloth that can be sewn together or attached to other cloths and yarns.

  
  

Weaving

• A loom is used to organize and hold the yarns of a woven project. Two sets of yarn are interlocked in the weaving process- the yarn used to keep the structure of the woven piece and the yarn used to decorate.

• A set of yarn is vertically wrapped around the loom and it remains in place during the entire weaving process. It gives the structure to the woven project. It is called the warp. The warp is later removed off the loom when the woven project is finished.

• The second set of yarns run horizontally in between the warp yarns. These yarns are called the weft. 

• The weft yarns are used to form patterns with colours, shapes, and textures.
