Lesson 6 Flashcards
Types of Fabric Dyes
Natural Dyes, Synthetic Dyes, Vat Dyes, Direct Dyes
Natural Dyes
From plants, minerals, and insects (e.g., indigo, turmeric)
Examples: Indigo: From the indigo plant (Indigofera tinctoria) produces shades of blue. Turmeric: From the turmeric root gives vibrant yellow hues. Madder Root: Yields red and pink tones. Onion Skins: Create warm orange to golden tones.
Synthetic Dyes
Chemically produced for vibrant, long-lasting colors.
Vat Dyes
Require a chemical reaction for dyeing fabrics like cotton.
Direct Dyes
Apply directly to fabric without a mordant.
Types of Synthetic Dyes
Azo Dyes, Acid Dyes, Basic Dyes, Reactive Dyes, Disperse Dyes.
Azo Dyes
Bright reds, oranges, and yellows; widely used in textiles.
Acid Dyes
Ideal for wool, silk, and nylon.
Basic Dyes
Used for acrylic fibers.
Reactive Dyes
Chemically bond with fibers, ensuring wash-fast colors.
Disperse Dyes
Designed for synthetic fibers like polyester.
What is a micallly bond?
A micallly bond is a bond to fibers, ensuring wash fast colors.
What are Disperse Dyes?
Disperse Dyes are designed for synthetic fibers like polyester.
What are the advantages of synthetic dyes?
They offer a brighter and more diverse color palette, greater resistance to washing, light, and chemicals, and cost-effective scalable production.
What considerations should be made for synthetic dyes?
Environmental concerns due to chemical waste and potential skin sensitivity for some individuals.
What are popular dyeing techniques?
- Tie Dye: Tying fabric to resist dye penetration.
- Batik: Using wax to resist dye in specific areas.
- Shibori: Japanese folding, twisting, and binding techniques.
- Ombre: Creating a gradient color effect.
- Ice Dyeing: Dye sprinkled over ice for unique patterns.
What is Tie Dye?
Tie dye is a resist dyeing technique where sections of fabric are tied, twisted, or folded to prevent dye from penetrating certain areas, creating unique, colorful patterns.
What are Tie Dye techniques?
- Spiral: Twisting the fabric into a spiral shape and applying dye in sections.
- Crumple (Scrunch): Scrunching the fabric randomly for a marbled effect.
- Stripe: Folding fabric accordion-style to create horizontal or vertical lines.
What is Batik?
Batik is a traditional dyeing technique where wax is applied to fabric to create patterns by resisting dye. Originating in Indonesia, batik is now practiced worldwide.
What is Shibori?
Shibori is a traditional Japanese resist dyeing technique involving manipulating fabric in various ways—folding, twisting, binding, or stitching—to create intricate patterns.
What is Ombre?
Ombre is a dyeing technique that creates a gradient color effect.
What is ‘Ombre’?
‘Ombre’ is a dyeing technique characterized by a gradual transition from one color to another, creating a smooth blending effect.
The term ‘ombre’ comes from the French word meaning ‘shaded’ or ‘shadow.’ This technique is widely used in fashion, textiles, hair coloring, and even in interior design due to its stylish and artistic appeal.
What is ‘Ice Dyeing’?
Ice dyeing is a creative and unpredictable dyeing method where powdered dye is sprinkled over ice, which then melts and transfers the color onto fabric.
This technique creates organic, watercolor-like patterns with beautiful blends and unexpected results.
What are tips for successful fabric dyeing?
- Pre-wash fabric to remove finishes.
- Use the right dye for the fabric type.
- Follow safety guidelines (gloves, masks, ventilation).
- Test colors on a sample first.
