Cellulose Fibres Flashcards
Q: What is acetate?
A: Acetate is a synthetic fiber derived from cellulose, known for its silk-like feel and elegant drape.
Q: How is acetate produced?
A: Acetate is produced by chemically treating cellulose from wood pulp or cotton linters with acetic acid and acetic anhydride.
List 4 working properties of acetate.
Generally crease-resistant
Sophisticated with an elegant drape
Moth proof and mildew resistant
Can be heat set for permanent creasing
Q: List 5 disadvantages of acetate.
A:Easily damaged by chemicals, such as nail polish remover
Melts in a flame and burns quickly
Very susceptible to electrostatic charge
Requires careful laundering to avoid damage
Low moisture absorption
List uses of acetate.
A: Acetate is used for dresses, blouses, and lining fabrics.
Q: Describe acetate.
A: Acetate is a synthetic fiber made from cellulose, valued for its silk-like appearance, sophisticated drape, and resistance to moths and mildew. It is generally crease-resistant and can be heat set for permanent creasing, but it is also susceptible to chemical damage, flammability, static charge, and requires careful laundering.
What is viscose?
A: Viscose is a cellulose-based fiber that resembles silk but is less expensive.
How is viscose produced?
A: Viscose is produced through a chemical process that converts cellulose from wood pulp into a soluble compound, which is then regenerated into fibers.
Q: List 4 working properties of viscose.
A: 1. Soft and fine texture, making it comfortable to wear.
2. Highly absorbent, though less than cotton.
3. Low electrostatic charge due to moisture content.
.4. Effective dyeing and printing with bright colors.
Q: List 5 disadvantages of viscose.
A: 1. Burns quickly (flammability).
2. Requires careful laundering.
3. Poor elasticity, wrinkles easily.
4. Lower strength than cotton.
5. Fibers can be easily damaged by rough handling.
Q: List uses of viscose..
A: Viscose is used in lining fabrics, blouses, shirts, dresses, drapes, lingerie, ribbons, and trimmings
Describe viscose.
A: Viscose is a soft, fine, and absorbent cellulose-based fiber resembling silk. It is used in various textiles but has lower strength and elasticity, requiring careful handling and laundering.
