Chemistry: A Truly Blue Sky

UPDATE Good news, I have received a brand new clean air particle counter from a professor I knew. According to this professor, this machine will be very helpful for my future experiments because it can count the air particles in a certain area. Using the quantitative results this can give me, I can produce data and soon make a conclusion through this helpful source.

Woven vs. Nonwoven? An important factor of the materials research is to exactly know what type of resources were used to make the filtering system from the Korean-made yellow dust masks. In order to know more about this, I started to investigate the basic facts of what I think I should know about fabrics and textures used in clothes and filtering systems. The huge distinction between various clothes or filtering materials is to see if it is woven or nonwoven. Woven is the past-tense term of the verb 'weave', which is to basically demonstrate any texture or cloth formed by weaving. According to Wikipedia, "Woven fabrics are often created on a loom, and made of many threads woven on a warp and weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another."

Let's look at the specific structure of the filtering system of the yellow dust masks that we wear every time. The facial masks that Koreans wear every day consist of three different types of core filters that depends on the mask, which are KF (Korea Filter) 80, 94, and 99, which can block 80%, 94%, and 99% of the air particles to go through. KF 99 is not really the best solution as you may think, because the higher the percentage, the more particles it may be able to block, but the harder it is for the host who is wearing it to breathe properly. When selecting what type of mask to use, it is more of a priority to consider your breathing conditions.

Cellulose: Cellulose, also known as (C6H10O5)n, like the chemical structure above, consists of
