1. Cotton vs. Silk T-shirts
Cotton: Comfortable, breathable, and highly absorbent. However, it is prone to deformation, fading, and wrinkling.
Silk Cotton: Lightweight, soft, and smooth with excellent breathability. It offers a more noble and elegant aesthetic.
2. Pure Wool vs. Blended Sweaters
Pure wool sweaters are softer, warmer, and more lightweight with a better ‘lofty’ or fluffy feel compared to blended versions.
3. Would be hot with Cashmere-Silk Blends for Summer?
Cashmere provides softness and moisture absorption for comfort. Silk features ‘winter warmth and summer coolness’, making it suitable for temperature regulation.
4. Benefits & Drawbacks of Cotton
Benefits: Derived from natural cotton fibers; skin-friendly and non-irritating; excellent sweat absorption.
Drawbacks: Prone to wrinkling, deformation, and color fading.
5. Properties of Spandex (Lycra)
Spandex has excellent elasticity and a smooth feel. It has low moisture absorption, retains shape well, and is machine washable.
Note: It has poor heat resistance.
‘Lycra’ is a brand name for spandex produced exclusively by DuPont.
6. Properties of Nylon (Polyamide)
Nylon (also known as Polyamide) has good dyeability, lightweight, and colorfast. It offers excellent windproof, waterproof, and wind-resistant properties with high elasticity.
7. Pros & Cons of Goat Cashmere
Pros: Lightweight, extremely warm, fine, soft, and highly absorbent.
Cons: Prone to pilling (small fuzz balls); requires specialized detergents and storage in a ventilated, dry place.
8. What is Mercerized Wool?
Features a soft luster, fine texture, and is highly breathable/absorbent. It is comfortable without being sticky, provides moderate warmth, keeps the wearer feeling fresh, and has good heat resistance.
9. What is Tencel Fiber?
A plant-based fiber known as the ‘cool and noble’ fiber. It absorbs and releases moisture quickly (non-sticky when sweating) and is relatively wash-resistant.
Drawback: Prone to wrinkling.
10. What is Acrylic Fiber?
Commonly known as ‘artificial wool,’ it is soft, retains heat well, is strong, and resists deformation or shrinkage.
11. What is Polyester-Cotton Blends?
Combines the softness of wool with the smoothness of silk. It features a bright yet soft luster, is wrinkle-free (non-iron), durable, and elastic, with lower shrinkage than pure silk.
12. Characteristics of Acrylic
Known as ‘artificial wool,’ it is soft and warm. It features a flat surface, tight structure, resists deformation, and shows minimal shrinkage after washing.
13. About Nanotechnology Fabrics
1. Durable water repellency.
2. Superior stain resistance.
3. Antibacterial properties.
4. High breathability.
5. Excellent tactile feel.
14. What is Acetate Fiber?
Chemically processed from natural cellulose. It mimics the style of silk—lightweight and comfortable with good elasticity and recovery. Cons: Difficult to wash; poor colorfastness.
15. Identifying Fibers via Sensory Perception
Cotton: Fine, soft, elastic, easy to wrinkle.
Silk: Lustrous, light, soft; produces a ‘rustling’ sound when squeezed; feels cool.
Wool: Elastic, soft luster, feels warm, wrinkle-resistant.
Polyester: High elasticity, smooth, strong, stiff, feels cool.
Viscose: Softer and more lustrous than cotton, but less durable.
16. Mercerized Wool Characteristics
Soft luster, delicate feel, high moisture absorption, and breathability. It keeps the body fresh while providing warmth and heat resistance.
17. Distinguishing Leather from Synthetic Leather
Leather: Smells slightly earthy; fine lines appear when folded; smooth luster and soft feel.
Synthetic: No fine lines appear when folded; smells like plastic/chemicals.
18. Eco-Textiles
Free of harmful dyes; uses chlorine-free bleaching; no formaldehyde residues; free of pesticides and heavy metals, meeting ecological safety standards.
19. Nanotechnology Shirts
Water, oil, and stain-resistant (Triple Self-Cleaning). Maintains 60% effectiveness after 25 washes (under 40°C), offering antibacterial and eco-friendly benefits for modern fashion.
