The Science of Fabrics: Reading Passage
Define Fiber:
Clothing starts with a fiber —a tiny strand. Fibers are spun into yarns and woven into fabrics. Fabrics are either natural (plants/animals) or synthetic (man-made chemicals).
Cotton Notes:
Cotton: The Natural King
Cotton is soft, breathable, and hypoallergenic. It absorbs water well but dries slowly. It is prone to shrinking or wrinkling when exposed to high heat in the dryer.
Polyester Notes:
Polyester: The Workhorse
A synthetic fiber made from petroleum. It is durable and wrinkle-resistant. It dries fast but isn't breathable, meaning it can trap odors and bacteria more easily.
Spandex Caution:
Spandex: The Stretch Factor
Spandex can stretch 500% and snap back. High heat is its enemy—it destroys the elastic fibers, causing the garment to permanently lose its shape.
Cleaning Notes:
Detergent Science
Detergents use surfactants to lift dirt. Use heavy-duty soaps for cotton and neutral pH "Sport" soaps for spandex to protect the elastic.
Knowledge Check
1. Which material is best for keeping you cool and is less likely to irritate sensitive skin?
A) Polyester
B) Cotton
C) Spandex
D) Nylon
2. Why does polyester dry faster than cotton?
A) It is made of plant fibers that naturally repel moisture.
B) It is a synthetic material that does not absorb much water.
C) It uses surfactants to move water away from the fabric.
D) It is significantly thinner than natural cotton strands.
3. What is the main danger of washing spandex in very hot water?
A) The shirt will grow much larger and lose all elastic properties.
B) The elastic fibers break down and the garment loses its shape.
C) The fabric will transform into a cotton-like texture over time.
D) The colors will turn bright white and fade almost immediately.
4. A "Sport" detergent is usually better for leggings because:
A) It has a neutral pH that protects sensitive elastic fibers.
B) It contains extra bleach to kill grass and heavy dirt stains.
C) It makes synthetic spandex fibers more breathable for athletes.
D) It contains a strong perfume that covers gym-related odors.

1. Which fiber is described as "hypoallergenic" and "highly breathable"?
A) Cotton
B) Polyester
C) Spandex
D) Nylon
2. What is a major disadvantage of polyester compared to cotton?
A) It shrinks easily in hot water
B) It takes a very long time to dry
C) It tends to hold onto oily odors and is less breathable
D) It is too expensive for most clothing items
3. Why should you avoid using high heat when washing or drying spandex?
A) Heat makes the colors bleed onto other clothes
B) Heat breaks down the elastic fibers, causing the shape to be lost
C) Heat causes the spandex to become too stretchy
D) Heat activates irritating chemicals
4. Which type of detergent is best suited for athletic wear made of spandex blends?
A) Heavy-Duty Detergent
B) Delicate or Sport Detergent
C) Bleach-based Detergent
D) Homemade Soap Scraps
5. What is the role of "surfactants" in laundry detergent?
A) They provide the pleasant scent of the laundry
B) They make the water hotter to kill bacteria
C) They lift dirt and oils away from the fabric
D) They help the clothes dry faster in the machine

Textile Tech Teacher Guide Teacher Guide: Fabric Science
Lesson Overview
This lesson introduces students to the materials science of their own clothing. By understanding the differences between natural (Cotton) and synthetic (Polyester, Spandex) fibers, students can make better decisions about garment care and sustainability.
Answer Key
1. B - Cotton: Breathable and hypoallergenic.
2. C - Odors/Breathability: Synthetics are plastic-based and trap oils.
3. B - Elastic breakdown: High temp damages elastane structure.
4. B - Delicate/Sport: Neutral pH protects elastic strands.
5. C - Lift dirt/oils: Surfactants are the active cleaning agents.
Classroom Discussion
Label Check: Have students find the fiber blend in their own shirts.Performance: Why do athletes avoid 100% cotton? (Water weight).Environment: Microplastic shedding from synthetics in the wash.
Quick Lab Idea
Place a drop of water on 100% cotton vs. 100% polyester. Observe absorption vs. surface tension!

What are Fibers?
Fibers are the building blocks of all clothing.
Natural
Grown from plants or animals (Cotton, Wool, Silk).
Synthetic
Created from chemicals/plastics (Polyester, Spandex).

How do we clean these tiny fibers?
The Magic Word: Surfactants
Molecules that act like magnets: one end loves water , the other end loves oil/dirt .
Heavy Duty
Enzymes break down stains. Use for Cotton & tough Polyesters.
Delicate / Sport
Neutral pH. Gentle on elastic fibers (Spandex).
Quick Quiz
Which fiber is best for breathability but prone to shrinking in high heat?
A) Polyester
B) Cotton
C) Spandex
D) Microfiber
Quick Quiz
High heat is the "enemy" of which material because it breaks down elastic fibers?
A) Denim
B) Polyester
C) Spandex
D) Silk
Check the Label!
The tag on your clothing isn't just an itch—it's a manual. Always check for fiber content and washing instructions!
