Class 6 Science: Fibre to Fabric Olympiad Questions

Fibre is a minute thin strand from which we can make clothes. These are the raw materials twisted to make yarns. Examples of fibres include cotton, wool, nylon, polyester, flax, jute, polyacrylic, and silk.

Yarn comes from fibres and is the source for making fabrics.

Fabric

Fabrics result from weaving the yarn along the length and breadth, forming a network. There are four types of fabrics

• Cotton fabric
• Woolen fabric
• Silk fabric
• Synthetic fabric

The process of making fabrics

First, the yarn is obtained from the fibres by a process called spinning. Yarns are long threads that are essential for making fabrics.

Three devices used to make yarn are as follows:

• Hand spindle
• Spinning wheel
• Spinning machines

The fabric is produced from the yarn by the following methods:

• Weaving
• Knitting

Weaving

It involves the making of the fabric by organizing the yarns at appropriate places. The weaving happens with the help of looms.

There are types of looms, which are handloom and power loom.

Knitting

Here a single yarn is used to make the fabrics. In knitting needles or machines, interlocking takes place to make fabrics. The process is possible using hands or with the help of machines.
