Class 6 – Chemistry | I – 6 Fiber to Fabric 1 1. Fiber to Fabric Solutions LEVEL-I 1. Correct option: (B) A very thin strand from which cloth is made is called a "fiber." Fibers are the basic units used to create fabrics. They can be natural or synthetic. Natural fibers come from plant or animal sources, such as cotton, wool, silk, and linen. Synthetic fibers are man- made and are created through various chemical processes, such as nylon, polyester, and acrylic. 2. Correct option: (C) Fabric is produced by weaving or knitting long, twisted threads called "yarn". Yarn is created by spinning or twisting fibers together to form a continuous strand. The specific type of yarn used, as well as the method of weaving or knitting, will determine the texture, appearance, and properties of the resulting fabric. 3. Correct option: (A) Yarn is a known as "spun thread" that is used for weaving or knitting fabrics. It is created by twisting or spinning fibers together to form a continuous strand. Yarn is the basic material for producing textiles, which are then used to create various types of fabrics through weaving, knitting, or other textile manufacturing processes. 4. Correct option: (C) Fabric is made up of fibers woven together. Fibers are the individual thin strands, either natural or synthetic, that is spun into yarn and then woven or knitted together to create fabrics. The process of weaving or knitting involves interlocking these fibers to form a stable and cohesive textile structure, which is what we commonly refer to as fabric. 5. Correct option: (D) Yarns are made of fibers. Yarn is created by twisting or spinning of fibers, whether they are natural (like cotton, wool, silk) or synthetic (like polyester, nylon, acrylic). These fibers are spun together to form a continuous strand, which is then used as the basic material for weaving or knitting fabrics. 6. Correct option: (A) Fibers are spun together to create yarn, and then yarn is used to produce fabrics or cloth. This sequence is correct: fibers → yarn → fabrics (cloth). 7. Correct option: (A) Natural and synthetic are two types of fibers. Natural fibers are derived from plant, animal and mineral sources, while synthetic fibers are man-made and produced through chemical processes. 8. Correct option: (A) The fibers obtained from natural sources like plants and animals are called "natural fibers." These include fibers like cotton, wool, silk, and linen that are directly sourced from nature without undergoing extensive chemical processing.
