Q17. Write two differences between woolen fabric and silk fabric.
Answers
Wool:
Wool is a great insulator of heat. The natural air pockets in wool help to efficiently keep the heat emanated by the human body inside and help people stay warm during cold weather. This is why sweaters are made of wool.
Silk:
Silk is also great in terms of insulation. However, most silk comforters and blankets don’t have the same density as their wool counterparts, meaning that they are not as good in terms of keeping warmth. However, due to the structure of silk fibers and most silk products being thinner, silk is better at facilitating air exchanges between the 2 sides of the comforter (more commonly known as breathing), which helps with venting excessive heat if required and keeping the temperature around the human body at a comfortable region
