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.
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
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.” 😅 11:04 “Stockings like the ones your mother wears. And like the ones your uncle wears, from what the neighbors tell me…”😅
Nowadays, we make all those fibers from oil- simply because it’s cheap and easier. We need to get our chemicals from biomass again. But we need to be able to get more out of it by using more waste products. It’s all about taking one thing and getting more out of it, or diversifying. Using biomass is more expensive than drilled oil, but it has to be done.
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!!!

I wish I could find a vintage lucite video
These videos are still better than have the rubbish made today,
ikr! I have a homework about Rayon and it's hard to find videos that explain like this
RIP the slaves of the Phrix rayon factory who were forced to make this material without any safety equipment.
Love the guy with the long gloves and goggles on but he has his sleeves rolled up past his elbows lol.
nice explanation
This kids are now grands
Wow, everyone should know this. This is scary! I don’t want this material on my body!

All from the humble spider and spinneret
Another chemical? WHAT other chemical??

What is chemical? 😂
Sodium hydroxide, also known as caustic soda or lye.
I think to break it down more
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
What the hex!
Hi
Follow
Any loyolite watching this I'm arron
I am
You mean A-A ron
Yup
lots of chemical
