Functions of clothing and its social impact
- Protection: from heat, cold, rain, sun (UV), insects and injury (helmets, safety shoes, lab coats).
- Modesty: covering the body as the culture expects.
- Identity: uniforms (police, nurse, school), team kits, and traditional dress such as the Indian sari, the Korean hanbok or the Scottish kilt, worn at festivals to show culture.
- Adornment and self-expression: colours, styles and accessories show personality and mood.
Clothes affect first impressions and how we feel about ourselves (self-image). Wearing suitable clothes for an interview or an event shows respect. But judging people only by clothes is unfair: style depends on money, culture and taste.
Choose clothes for the weather: light, loose and light-coloured in heat; layers in cold, because air trapped between layers keeps heat in; waterproof outer layer in rain.
Fibres and fabrics
A fibre is a very thin hair-like strand. Fibres are spun into yarn, and yarn is made into fabric.
| Fibre | Source | Good points | Weak points |
|---|---|---|---|
| Cotton | Plant (cotton boll) | Soft, absorbs sweat, breathes | Creases, shrinks, dries slowly |
| Linen | Plant (flax stem) | Very cool, strong | Creases a lot |
| Wool | Sheep, goat | Warm (traps air), springy | Can shrink and felt in hot water, itchy |
| Silk | Silkworm cocoon | Shiny, smooth, light | Costly, needs gentle care |
| Polyester | Synthetic (petroleum) | Strong, dries fast, few creases | Hot in summer, sheds microplastics, melts near flame |
| Nylon | Synthetic | Very strong, stretchy | Poor absorbency |
Blends (for example 65% polyester / 35% cotton) mix good points: comfort plus easy care.
Weaving crosses two sets of threads over and under (strong, little stretch: jeans, shirts). Knitting links loops (stretchy, comfy: T-shirts, socks).
Elements of design, tools and sewing skills
- Line: vertical lines lengthen, horizontal lines widen, diagonal lines add energy.
- Colour: dark colours look slimmer and hide stains; light colours reflect heat.
- Shape / silhouette: the outline of the garment (straight, A-line, fitted).
- Texture: how the fabric feels and looks (smooth silk, rough denim).
Tools: measuring tape, fabric scissors, pins, needles, thread, tailor's chalk, sewing machine, iron. Today also computer-aided design (CAD) and 3D body scanning.
Basic procedure: take body measurements → choose a pattern → lay pattern on fabric along the grain → pin and cut → sew seams → press → finish (hem, buttons). Simple repairs everyone should know: sewing on a button, fixing a hem, mending a small tear.
Wardrobe planning, evaluating and buying clothes
Wardrobe planning: list what you have, what you need (school, sport, festivals, weather), what can be mixed and matched, and your budget. Your needs change as you grow, change school or move city.
Evaluate before buying:
- Fit: you can move, sit and lift your arms.
- Quality: straight even stitches, matching patterns at seams, strong buttons and zips.
- Care label: fibre content, washing temperature, ironing, dry-clean symbols.
- Cost per wear = price ÷ number of times worn. A ₹900 shirt worn 60 times costs ₹15 per wear; a ₹300 shirt worn 5 times costs ₹60 per wear.
Where to buy: department stores, brand shops, local markets, online shops (check return policy and size chart), second-hand and thrift shops, rental and swap events. Watch out for sale tricks: 'buy 2 get 1' only saves money if you needed the clothes.
Fabric care and sustainable clothing
Care symbols: a tub = washing (number = maximum °C, a hand = hand wash); a triangle = bleach; a square = drying; an iron with dots = ironing heat (1 dot cool, 3 dots hot); a circle = dry clean. A cross means 'do not'.
Sustainability: making clothes uses a lot of water and energy (about 2,700 litres of water for one cotton T-shirt), and fast fashion creates mountains of waste. Plan to:
- Buy less, choose well: durable clothes you will wear many times.
- Care: wash cold and full loads, air-dry.
- Repair and upcycle: turn old jeans into a bag.
- Pass on: hand-me-downs, donation, swaps, recycling bins.
Future clothing: smart textiles that check heart rate, fabrics from recycled bottles or plant waste, 3D-knitted clothes with no waste, and digital clothes for avatars.
Investigating clothing questions
- Explore: ask a clear question, for example 'Which fabric dries fastest?' or 'How do teens choose clothes?'.
- Investigate: test (same size swatches, same water, time to dry), survey classmates, read labels, use trusted sources.
- Process: put results in a table or chart; look for patterns; check if the test was fair.
- Communicate and reflect: share a poster or slides; say what you would improve next time.
Key formulas and definitions
- Cost per wear = price ÷ number of times worn
- Fibre → yarn → fabric → garment
- Natural fibres: plant (cotton, linen, jute), animal (wool, silk); synthetic: polyester, nylon, acrylic
- Woven = over-under threads (strong); knitted = loops (stretchy)
- Care label: tub = wash, triangle = bleach, square = dry, iron = iron, circle = dry clean; X = do not
Worked examples
1. Jacket A costs ₹2,000 and you will wear it 100 times. Jacket B costs ₹800 and will last 20 wears. Which is cheaper per wear?
A: 2000 ÷ 100 = ₹20 per wear. B: 800 ÷ 20 = ₹40 per wear. Jacket A is cheaper per wear, even though its price is higher.
2. Choose a fabric for a school sports shirt worn in 35 °C heat.
A polyester–cotton blend or a moisture-wicking polyester: it dries fast and is easy to care for, while the cotton part adds comfort. Pure wool would be too hot.
3. A label shows a tub with 30, a crossed triangle and an iron with one dot. What does it mean?
Machine wash at no more than 30 °C, do not bleach, iron on a cool setting.
Common mistakes
- Thinking silk is synthetic. Silk is a natural animal fibre made by silkworms.
- Buying only by price. A cheap item that is worn a few times can cost more per wear than a better one.
- Washing wool in hot water. It can shrink and felt; use cool water and gentle washing.
- Thinking a cross over a symbol means 'yes'. A cross always means 'do not'.
