| 1. What are the different types of fibers? |  |
Ans. There are two main types of fibers: natural fibers and synthetic fibers. Natural fibers include cotton, wool, silk, and jute, which are derived from plants or animals. Synthetic fibers, on the other hand, are man-made and include materials such as polyester, nylon, and acrylic.
| 2. Which type of fiber is cotton? | |
Ans. Cotton is a natural fiber that comes from the cotton plant. It is widely used in the textile industry due to its softness, breathability, and absorbency. Cotton fibers are typically spun into yarn or thread and then woven or knitted to make various fabrics.
| 3. What are the advantages of synthetic fibers? | |
Ans. Synthetic fibers have several advantages, including their durability, strength, and resistance to wrinkles and shrinkage. They are also often less expensive than natural fibers and can be engineered to have specific properties, such as moisture-wicking or UV protection.
| 4. How are synthetic fibers made? | |
Ans. Synthetic fibers are made through a process called polymerization. In this process, small molecules called monomers are chemically combined to create long chains known as polymers. These polymers are then spun into fibers. Different types of synthetic fibers, such as polyester or nylon, are made from different polymers.
| 5. What are some common uses of natural fibers? | |
Ans. Natural fibers have a wide range of uses. Cotton, for example, is commonly used to make clothing, bed sheets, and towels. Wool is often used for making warm clothing and blankets. Silk is highly valued for its smooth and luxurious feel, making it suitable for high-end clothing and home furnishings. Jute, a natural bast fiber, is commonly used to make bags, rugs, and other durable products.
