The Dental Bibs designed to protect the patients clothing from during an examination, Surgery or cleaning in the dentist's office. Today, the tattoo artists and piercier use it to protect their work station.

A dental bib composed of a very durable two-ply paper and 1 Ply film,  It prevents liquids from being soaked through. 2 ply paper will help absorbing liquid and avoiding spills. The 1ply film is used to prevent liquid leaking, waterproof.

But do you now how to choose a good dental bibs.

First we need to know from the material, a good dental bibs are made of new ply paper and 100% Ply film,  the cheaper dental bibs are made by recycle paper and a 60% ply film.

When you compare the two qualities dental bibs, you can feel the cheap one is thiner and softer then the good one,

Second, a good dental bibs, the three layers are closely integrated, but the cheaper one is easy to separate it

Next we are going to show you a test, to see the difference between the two quolitities dental bibs

At first, we are testing the water absorption.

I will use the syringe to put half mili liter water to the front side of the dental bids to test the water absorption, and record the water leaking speed. 

You can see the differences of the water absorption between the 2 qualities dental bibs.

Now we are testing the waterproofing quality:

I will use the syringe to put 1 mili liter water to do backside of the dental bibs to test the waterproofing quality and record the water leaking speed

You can see the differences of the water waterproofing between the 2 dental bibs.

The experiment is acutally shooting for 2 hours
