To neutralize the HCl formed during polymerisation.
1,6 diaminohexane + diacid chloride -> nylon 6,10 + HCl
2 HCl + Na2CO3 -> 2 NaCl + H2O + CO2
It would be disadvantageous to leave out the Na2CO3 because the chloride acid produced in the reaction would cause for a lower yield. By adding the sodium carbonate the reaction is driven more toward the products resulting in a higher yield. The use of inorganic bases would also increase the strength of the polymer "rope."
a great paper on this is "The Nylon Rope Trick" by Paul Morgan and Stephanie Kwolek http://www.usm.edu/pattonresearchgroup/PSC341/jce.pdf

Why is sodium hydrogen carbonate used as a treatment for ant stings?
A paste of sodium hydrogen carbonate can be used to relieve the pain of the ant bite.
What does a sodium hydrogen carbonate indicator do?
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.
Why is dilute sodium hydrogen carbonate solution used in a beaker when doing an experiment to find out about photosynthesis?
sodium hydrogen carbonate provides carbon dioxide for the plant to photosynthesise
If 2 moles of sodium carbonate are used in the reaction how many grams of sodium chloride will be formed?
234 grams
Why sodium carbonate is used in preparation of thiosulphate solution?
To ensure the stability of the solution
What is the use of sodium carbonate in agriculture?
Sodium carbonate is not used in agriculture.

What the importance of adding sodium carbonate in phenol content determination?
since sodium carbonate is a strong base, it is used for neutralizing reaction.
Is ball mill used as a raw material for the commercial preparation of soda ash sodium carbonate?
A ball mill is a machine used for grinding chemicals, not a raw material. It's not used in the manufacture of sodium carbonate because the process they use to make sodium carbonate kicks it out as a usable powder. In the US, we don't use the synthetic way because we have a LOT of a mineral called trona in Wyoming - so much that it supplies a quarter of the world's sodium carbonate requirements. That is turned into sodium carbonate by digging it out of the ground, grinding it in a rock crusher, dissolving the sodium carbonate into water, then filtering the solution and evaporating it...once again, producing a usable powder.
What processes are used to make glass?
Essentially glass is obtained by the melting of mixture silica sand - sodium carbonate.
What are Carbonates used for in your every day lives?
medication - calcium carbonate factories- sodium carbonate
What is the common use for sodium carbonate?
Sodium carbonate is an odorless, white, alkaline powder that is used by manufacturers in making soap and glass. Sodium carbonate is somewhat similar to sodium bicarbonate in terms of their chemical composition; the difference is that sodium bicarbonate is a household item which may be used in cooking while sodium carbonate is used for cleaning.
What is sodium percarbonate and sodium carbonate?
Sodium carbonate is the sodium salt of carbonic acid. Carbonic acid is also called carbon dioxide which is the bubbles is soda pop. Sodium Bicarbonate is the double sodium salt of carbonic acid. Another name for Sodium Bicarbonate is baking soda which releases carbon dioxide when heated to make bread rise. Boiling Sodium Bicarbonate in water to dryness leaves behind a white residue of Sodium carbonate. Sodium percarbonate is combination of two Sodium carbonates with 3 hydrogen peroxide to make a dry powder sometimes used in whitening powders.
Is sodium carbonate used in septic tanks?
Sodium carbonate can safely be used in septic tanks. Many people use it to deodorize the drains in their home. It does not cause problems with the septic system.
Why do mummies get beard with salt?
The salt used to prepare a mummy is sodium carbonate not sodium chloride.
