In this lesson, you will learn about the ways in which various materials are used in making common household items, in construction of houses and other buildings. Joseph Swan invented one of the first artificial fibres in the early 1880s; today it would be called semisynthetic in precise usage. Additionally, it is used in yarns for weaving, especially in crochet. 1 0 obj These compounds are increasingly being used, particularly in the aerospace industry. But technology has made it possible to turn renewable resources into plastics and synthetic gums. You must be familiar with many plastic articles used everyday. This capability is very useful since it can help design other intelligent materials, such as sensors and alarms. Rayon is mixed with wool to make carpets. It is easy to dye in a wide range of colours. Plastic is also a polymer like the synthetic fibre. Some of these materials such as wood, cotton, stones and clay are natural materials. It is stronger and more durable than rubber and was invented in the 1950s. Rayon drapes just as well as natural silk, is easy to dye, and is highly absorbent. Better, stronger and safer.

It is a familiar nylon, is considered a super polymer and was introduced to the market in the 1970s. A parachute needs to strong as it has to withstand high speed wind and huge amount of air pressure. Polyester is highly stain resistant; The only dyes that can dye it are so-called dispersed dyes. Different chemical compounds are used to make different types of fibers. In this process, high temperatures are used to change and shape the shape and dimensions of the fibers or synthetic materials. For example, the blend between polyester and cotton, poly cotton, is a strong, wrinkle-resistant and non-shrinking fabric. It is used to make curtains, bedsheets etc. 1.1 INTRODUCTION As we all know we use a number of materials in our daily life. Answer. Kevlar is a very strong plastic.
