Comprehensive notes, formulas, and practice questions for Spinning.
Spinning
Spinning Yarn
What you'll learn
- Spinning — twisting fibres into yarn (thread) strong enough for weaving or knitting.
- Traditional methods — charkha, hand spindle; modern spinning machines in mills.
- Difference between yarn and fabric — yarn is intermediate; fabric is woven/knitted cloth.
- Gandhi's charkha and khadi as historical link to self-reliance (NCERT context).
Key concepts
Level 1 — From fibre to yarn
Verbal: Loose fibres are too weak alone; twisting binds them into continuous yarn.
Visual (hand spinning):
| Step | Action | Result |
|---|---|---|
| 1 | Clean & card cotton | Aligned fibres (sliver) |
| 2 | Draw out thin strand | Even thickness |
| 3 | Twist with charkha | Continuous yarn on spindle |
Tools: Charkha (spinning wheel), takli (spindle), factory ring frame (modern mill).
Level 2 — Weaving, knitting, and quality
After spinning: Yarn → weaving (loom: warp + weft) or knitting (interlocking loops) → fabric.
Count of twist: More twist → stronger yarn; less twist → softer yarn.
Khadi: Hand-spun + hand-woven — unique texture; supports rural employment.
Defects: Uneven spinning → lumps in cloth; broken yarn → weak spots.
Career link: Textile industry — ginning → spinning → weaving → dyeing → garment.
Worked example
Trace cotton from boll to handkerchief.
Step 1 — Ginning: separate cotton fibres from seeds
Step 2 — Carding: align fibres into sliver
Step 3 — Spinning: twist into yarn on charkha or machine
Step 4 — Weaving: interlace yarn on loom → cloth
Step 5 — Cutting & stitching → handkerchief
Common mistakes
| Mistake | Why it happens | Fix |
|---|---|---|
| Yarn = fabric | Skipping weaving step | Yarn is thread; fabric is woven/knitted sheet |
| Spinning weaves cloth | Mixing processes | Spinning makes yarn; loom weaves |
| All thread is synthetic | Sewing thread variety | Cotton thread also spun yarn |
| Charkha only historical | Not seen in cities | Hand-spinning still produces khadi |
