Ep 19. Carbon Fibre Car Parts, Hand Dryers, Recycled Polyester Yarn, Fleece

How It's Made is a popular documentary-style television show that explores how everyday objects are made. Season 6 episode 19 of the show highlights four different products: carbon fiber car parts, hand dryers, recycled polyester yarn, and fleece.

The episode begins by taking a look at how carbon fiber car parts are made. Carbon fiber is a lightweight, strong material that is perfect for making car parts because it can withstand high temperatures and doesn't corrode. To make carbon fiber, a material called precursor is first heated up and stretched into fibers. The fibers are then woven together to create a fabric. The fabric is coated in resin and heated up to create a solid, durable material that can be molded into various car parts, such as hoods and spoilers.

Next, the show explores how hand dryers are made. There are many different types of hand dryers, but most work by blowing hot air onto wet hands to dry them off quickly. The inside of a hand dryer is made up of several different components, including a motor, heating element, fan, and sensor. These components are assembled together and tested to make sure they are working correctly before the hand dryer is packaged and shipped out.

The third segment of the episode focuses on recycled polyester yarn, a sustainable material made from old plastic bottles. First, the bottles are sorted and cleaned to remove any labels or debris. Next, they are shredded into small pieces and melted down into a molten liquid. The liquid is then extruded through small holes to create long strands of polyester yarn, which are wound onto spools. This recycled yarn can be used to make a variety of products, from clothing to carpeting.

Finally, the episode takes a look at how fleece fabric is made. Fleece is a soft, warm material that is perfect for making jackets, sweaters, and blankets. To make fleece, polyester fibers are first spun into yarn. The yarn is then knitted into a fabric and brushed with metal blades to create a soft, fluffy texture. The fleece is then dyed and finished before it is cut into pieces and sewn together to make a finished product.

Overall, season 6 episode 19 of How It's Made provides an interesting and informative look at how four different products are made. From the high-tech process of making carbon fiber car parts to the sustainable production of recycled polyester yarn, viewers will gain a new appreciation for the manufacturing process behind everyday objects.
