Fibre to Fabric
Students learn how natural fibres like **cotton, jute, silk, and wool** are obtained and converted into fabrics. The chapter covers the process of **spinning, weaving, and knitting**, helping students understand how clothes are made.
Key Topics & Instructions
▼- Identify the source (plant/animal) of common natural fibres.
- Understand the sequence of processes that turn fibre into yarn, and yarn into fabric.
- Differentiate between weaving and knitting.
- Use Experiment 1 to explore the source and characteristics of a chosen natural fibre.
- Use Experiment 2 to simulate the sequence of steps that turn raw fibre into final fabric.
Experiment 1: Fibre Source and Property
Select a natural fibre to identify its source and key properties.
Experiment 2: Fabric Manufacturing Sequence
Simulate the process of converting fibre into a final fabric.
Plant Fibres (e.g., Cotton, Jute): Obtained from plant parts (seed hair, stem bark). Animal Fibres (e.g., Wool, Silk): Obtained from animal sources (fleece, silkworm cocoon). These fibres are long polymer chains, giving fabric its strength and elasticity.
Manufacturing Processes
The process of converting raw **fibre** into **yarn** (thread) by twisting the fibres together. Done using traditional tools like the *charkha* or modern spinning machines.
The process of arranging two sets of **yarn** (warp and weft) together at right angles to make a piece of **fabric**. Done on a *loom* (handloom or power loom).
The process of making a piece of **fabric** from a single **yarn** by forming interlocking loops. Used to make sweaters, socks, etc.
