00:00Thousands of years ago, when the earth was too cold and man lived in caves,
00:10he started to use the skin of dead animals to cover his body.
00:19He discovered that this protected him from cold and rain.
00:26As the weather changed, they made clothes from grass and the bark of trees.
00:36Plants and animals do not need any clothes.
00:42Human beings are the only living things who wear clothes.
00:49We use clothes to cover our body.
00:54Clothes protect us from cold, wind, rain and the heat of the sun.
01:11Clothes make us look smart too.
01:16Man has progressed.
01:19He has started using different materials for making clothes.
01:26Fibers
01:28The materials which we use to make clothes can be classified into natural fibers and artificial fibers.
01:40Natural Fibers
01:42Fibers obtained from plants
01:47The most important fiber obtained from plants is cotton,
01:54which is the most widely used fiber for making clothes.
02:01Cotton clothing is good for summer wear.
02:06Plants like banana,
02:11hemp
02:14and jute also give us fibers.
02:20In earlier days, thick rough fiber was produced from jute.
02:28But now, modern technology has transformed all that and we get fine fibers from jute, banana and hemp.
02:41Fibers obtained from animals
02:45Most animals have a thick covering of hair on their bodies.
02:50This hair is used as fiber to weave clothes.
02:58The most commonly used hair fiber is obtained from sheep.
03:05The hair covering the sheep's body is known as fleece.
03:13We get wool from this fleece.
03:17People living in cold countries use woolen clothes almost throughout the year.
03:26Yak wool is very popular in cold mountainous regions.
03:34Blankets are woven from woolen fibers.
03:40We get silk from the silkworm.
03:46Silk cloth is fine and shiny.
03:52It is more expensive than cotton.
