Non Cellulose Fibres Flashcards
Card 1: Question: What is Nylon?
Answer: Nylon is a synthetic polymer fiber known for its strength, elasticity, and durability. It was first produced in the 1930s as a substitute for silk.
How is nylon produced?
Nylon is produced through a chemical process called polymerization, which involves the reaction of monomers to form long chains of nylon polymers, which are then spun into fibers.
List 7 working properties of nylon
Very strong with excellent abrasion resistance
Resilient and wrinkle-free
Soft and comfortable to wear
Dries quickly and needs little or no pressing
Can be heat-set for permanent creasing
Insulation properties vary depending on the textile
Shrinks and melts away from a flame
List 5 disadvantages of Nylon
Susceptible to electrostatic charge
Frays easily
Can be damaged by some acids and bleaching agents
Non-absorbent, not suitable for children’s wear or summer wear
May be uncomfortable in hot weather
List uses of nylon
Sheer stockings, lingerie, foundation garments, swimming, sports and leisure wear, linings, dresses, blouses, weather-proofed clothing, sewing thread, umbrellas.
Describe Nylon.
Answer: Nylon is a strong, resilient synthetic fiber known for its durability and versatility. It is comfortable to wear, dries quickly, and can be heat-set for permanent creases. However, it is non-absorbent and susceptible to static electricity.
What is Polyester?
Answer: Polyester is a synthetic polymer fiber known for its versatility and durability. It was first introduced in the 1940s and has become one of the most widely used fibers globally.
How is Polyester produced?
Answer: Polyester is produced through a process called polymerization, which involves reacting chemicals to form long chains of polyester polymers, which are then extruded into fibers.
List 7 working properties of Polyester.
Answer:Durable with excellent abrasion resistance
Resilient and wrinkle-resistant
Can be heat-set for permanent creasing
Soft and comfortable to wear
Insulation properties vary based on the textile produced
Shrinks and melts away from a flame
Not damaged by sunlight through glass, ideal for curtains
List 5 disadvantages of Polyester.
Answer
:Susceptible to electrostatic charge
Non-absorbent unless blended with other fibers
May feel less breathable compared to natural fibers
Can retain odors more than natural fibers
Environmental concerns due to synthetic production
List uses of Polyester.
Answer: Suits, dresses, shirts, blouses, leisure wear, rainwear, workwear, children’s nightwear (with flame-resistant finish), often blended with wool, cotton, or viscose.
Describe Polyester.
Answer: Polyester is a durable, versatile synthetic fiber known for its excellent abrasion resistance and low maintenance. It is used in a wide range of textiles, often blended with other fibers for enhanced properties. It is resilient, quick-drying, and resistant to many chemicals and biological agents.
What is acrylic?
Answer: Acrylic is a synthetic fiber made from polymers derived from petroleum or natural gas, known for its softness, warmth, and wool-like texture.
How is acrylic produced?
Answer: Acrylic is produced by polymerizing acrylonitrile to form polyacrylonitrile (PAN), spinning the polymer into fibers, drawing them to align the molecules, and then finishing them with treatments to enhance specific properties.
List 7 working properties of acrylic.
Answer:
1. High elasticity
2. Strong and durable
3. Soft and warm
4. Moisture absorbent
5. Good thermal insulation
6. Quick drying
7. Easy to launder
