Hi, I am interested to know whether the feed stock material can be changed from wood to coir fiber. Coir fiber has a high percentage of lignin like wood and it is a renewable and sustainable material.
Hi! As long as yopu can separate out the cellulose from the coir, it should be working fine. The challenge is to get rid of for example silica, and to get a pure enough cellulose. Please Google for MoRe Research, then you will find my name under contacts :-)
lovely images, could use some atmospheric sound to make the gaps between speech less jarring. Just record the room where you record the voiceover, and put that recording under everything continuously. Can be looped.
Basically you can use paper grade pulp to produce viscose fibers, but the cost will be high due to higher consumption of alkali and a lower yield due to the large fraction of low molecular carbohydrate polymers. Usually a pulp with a R18 (how much is insoluble in 18% aqueous NaOH) of above 94 is used.
You can make viscose from basically any cellulose from nature. The only challenge is to remove enough other components in the starting material. The cellulose has to be rather pure.
so this is how viscose is made. Interesting. Thank you for posting.
What do you filter viscose through? Thanks for video!!
If the fiber becomes white again, why are 100% rayon/viscose shammy cloths orange?
Kan man framställa viskos hemma i liten skala?
Very good. Thank you have explained how to make viscose fiber. But, may i ask something. Why ball fall viscose must 55-60 second for spinning flow.
Hello, what is the composition of spinneret bath solution. Is it acid solution?
Yes. Dilute sulphuric acid

Could you please tell me the cost of the whole machine setup
What is ideal ripening age of viscose
It depends on the application :-)

Have carbon di sulphide stay in the viscose fibre?
No, it is removed in the acid wash
Hi I would like to ask can bacterial cellulose make into viscose?
Joe Chan
Did you try to make viscose from bacterial cellulose?
Yes!
Is this technology on making polyester fabrics from jute.
No, it is to dissolve cellulose in NaOH with the aid of CS2, and then regenerate the cellulose into viscose fibres.
great video and well explained.
I am going to start a project on viscose. I would like to contact with you. Please mail me.
Hi! You can Google for MoRe Research Sweden, then you will get in contact with our company.
What will be the purity of cellulose required to produce high quality viscose? Can the same cellulose used for paper be used?

is it possible to make Viscose from jute plant.
Viscose use wood pulp as a starting material.

good job . . it is very clear video
03:30 "The yellow color comes from.." whaaaaat ??
Nora ISSILAME carbon disulphide
Carbon disulphide
Actually, it comes from side-reactions (by-reactions in the video) when CS2 reacts with NaOH for example.,
well explanations about viscose.
where are you been all my life, we need your expertise, we will contact you shortly
well explained
nice explanation by means of video
makin' dope. just a legal version. nice.
Good one!
it seems like you are compelled to speak unfortunately :P
.
you talk like you didn't sleep may be one month..you are so sleepy!!!
Gd video
Normal Swedish accent
i will dislike every komment
