Yellow Dust Mask: Structure and Materials (Part 2)
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."
On the other hand, nonwoven products are basically products that are "sheet or web structures bonded together by entangling or filaments (and perforating films) mechanically, thermally, or chemically.", according to INDA.org.
Based on this definition, as well as the images provided from the previous blog (Yellow Dusk Mask: Structure and Materials (Part 1)) we can be sure that masks in general, including medical masks, are made of web structures that are literally entangled to each other, just as the image provided.
