Chlorine vs Bromine & Nylon vs Lycra - What is Best for Suits?

Chlorine vs Bromine & Nylon vs Lycra - What is Best for Suits?

Post by Marianne Eag » Tue, 30 Nov 1999 04:00:00


We are conducting an experiment for the annual school science fair.

Materials:
6 petri dishes
Dark blue Nylon material (3 pieces)
Dark blue Lycra material (3 pieces)
1/4 tsp Bromine powder mixed into  1/4 cup distilled water
1/4 tsp Chlorine powder mixed into  1/4 cup distilled water

Place nylon in 1 petri dish containing chlorine solution
Place nylon in 1 petri dish containing bromine solution

Place lycra in 1 petri dish containing chlorine solution
Place lycra in 1 petri dish containing bromine solution

Place nylon in 1 petri dish containing only distilled water
Place lycra in 1 petri dish containing only distilled water

Observations 24 hours later:

Nylon and lycra maintain their color in the distilled water

Nylon is slightly faded in chlorine solution, but barely so.
Lycra is slightly faded in chlorine solution, alittle more than the
Nylon, but still not very noticeable.

Nylon is noticeably faded in the bromine solution
Lycra color in bromine is a light yellow and by far the most degraded.

So far it appears that nylon is more durable than lycra and that bromine
degrades suits faster than chlorine.

Perhaps. But color is not everything. How are you assessing
the integrity of the material? Loss of elasticity? Thinning?
These factors are more important than color changes.

Don asks good questions. We WILL look at all the factors he mentioned
(material elasticity, etc) once we remove the materials from solution.
We are leaving them in for 3 days. We will also repeat the experiment
with lower concentrations. THEN we will report on these other factors of
material durability.

Oh. OK, that sounds great. Please be sure to post your results.
Enquiring minds want to know!

regards,
Don

What do you mean by chlorine and bromine powders?  The concentration of
whatever you use is very important as well.

The only way we can measure "concentration" is to use the same amounts
of bromine and chlorine powder. I was told when I bought the products
triannehat actually the bromine needs about twice the amount to equal what
the amount of chlorine that would be put into a pool. Thus, 1/4 tsp of
bromine would be ~ to 1/8 tsp chlorine. However, for the exp I used
the same powder amounts. Hence, if bromine at this "half" concentration
reacts so much quicker than the chlorine, how  much worse would it be
if I used it at the recommended chlorine: bromine (ratio)?

Very interesting post.  Nice going.

By the way, I learned the hard way not to use my rash guard (for use under a
wetsuit) in a swimming pool.  It ruined the material after a few swims.
