Synthetic Fibers: Nylon and Rayon (1949)

Reveals how modern science and technology have made possible the development of new artificial fibers for making textiles -- specifically rayon and nylon. Portrays some of the processes used in making these fibers, ways in which they are useful to man and characteristic of the textiles made from them.

Bravo! Was looking for something to explain how rayon is made, never expected the best explanation on youtube to be something from 1949. Excellent vid, showed me exactly what i wanted to see.

Thank you for an important historical video. Regrettably, the film pays very little attention to health and safety matters that were well known at the time it was made. The "chemical bath" mentioned early in the rayon segment was carbon disulfide, which was described as a neurotoxin in the nineteenth century by Jean-Marie Charcot, the French neurologist who gave Parkinson's disease its official name. Early in the twentieth century it it was shown to produce cardiovascular disease in exposed workers by Dr. Alice Hamilton, one of the founders of the field of occupational medicine in the US. In the 1930s Dr. Hamilton, by then a professor at Harvard, was asked to investigate a possible epidemic of CS2 related cases of neurological disorders in a Dupont rayon manufacturing facility in Delaware but was denied entry to the plant. Today CS2 is recognized by NIOSH as also causing diseases of the kidneys, skin, and other organs. Modern chemical safety guidelines unanimously recommend elimination of exposure to workers by completely enclosing chemical processes or, when necessary, provision of chemical resistant personal protective equipment with respiratory apparatus.

Thanks for your comment

Interesting, I remember that Rayon was made from Wood. However, I did not know that Nylon was made from Coal. Would be interesting to see the progress of these synthetic fibers in industry (i.e. Tires) as well as fashion wear (i.e. clothing). Thanks for the video.

it's cool that they offer something useful. It's just a bummer that the process can be quite toxic for the employees and environment surrounding it. See this video: th-cam.com/video/-HE23QvF0gE/w-d-xo.html

[@firstnamesecondname5341]

These videos are still better than have the rubbish made today,

[@rhaf4264]

ikr! I have a homework about Rayon and it's hard to find videos that explain like this

[@hallerd]

RIP the slaves of the Phrix rayon factory who were forced to make this material without any safety equipment.

[@akhiltoshniwal3536]

nice explanation

Love the guy with the long gloves and goggles on but he has his sleeves rolled up past his elbows lol.

I wish I could find a vintage lucite video

This kids are now grands

[@evangelinehoke5512]

Wow, everyone should know this. This is scary! I don’t want this material on my body!

[@catherineleavy3746]

I just found this in HOLT GENERAL SCIENCE! 😅😂 The chinese learned how to unravel the cocoons of silk moths that were woven into silk cloth.. also around 2500 B.C the Egyptians learned how to make paper by matting fibers from a reed called the papyrus. Rayon, the first synthetic fiber was introduced in 1910 as a substitute for silk. The new synthetic fibers are polymers formed by joining together thousands of small molecules into long chains of atoms! Fiber- reinforced composites! I can't type it all optical fibers will revolutionize telephone communications! LOOK AT THE LABELS ON YOUR CLOTHES!!!

This and other educational films are begging for a RiffTrax treatment 😊
7:23 “Well boys, you’ll learn the answer to that after you’re married…” 😅
8:20 Unfortunately there’s a lot of other names people got used to using everyday… 😢
9:34 “You boys will go through an important chemical change too in a few years. But that’s a topic for a different film.” 😅

What is chemical? 😂

[@CriticalBrony]

Sodium hydroxide, also known as caustic soda or lye.

[@mysticbodi580]

I think to break it down more

[@sangetube]

I had a read about it. It's copper hydroxide dissolved in a solution of ammonia called Cuprammonium. They don't use this method anymore
