There are a lot of types of cotton as it is used for many purposes. Because there’s too many, it can’t be all covered in this article, but I am going to list mainly on the types of cotton that we can access quite easily.
Cotton is a natural cellulose-fiber (the main components of textiles are plant fibers) made from cotton wool. Cotton fabrics are used for a wide variety of purposes in our daily lives, including clothes, underwear, dishcloth, bedding, curtains, towels, and napkins. And this fabric has high utilization to be used throughout all four seasons. As such, cotton is a familiar fiber to us, but we often don't know what features it has and what points we need to be careful of. So, let’s take a look at some things to know about cotton.
The HEPA filter of the air purifier or the liquid filter used in the water treatment process are also made of Melt-blown. Not only that but Melt-blown is also used for filter purposes, as well as sanitary materials, clothing, packaging materials, and battery separator.
There are many types of copper masks. Among them, when comparing Medifiber Blue Mask and Scasis CF Mask, the Medifiber mask is like its name sake a blue mask as opposed to the normal white mask. This is because a special fiber combining copper ions surrounds the outer surface of the mask. You can think of it as a form of applying an antibacterial film to the mask surface. And since this mask contains a replaceable interior it can be used multiple times by replacing the interior. This mask recommended for those who are concerned about the virus attached to the mask surface or those who think it is a waste to wear a disposable mask every day. However, it is necessary to pay special attention to surface contamination while using it.
According to a review of copper published by Kobert in 1895, copper has been used to treat acute chronic diarrhea, and epidemics like cholera. It is also said to be effective for eczema, tuberculosis, and syphilis thanks to various minerals within copper. And in 1966, John R. J. Sorenson proved that the silver-copper complex was effective in treatment. Copper complexes have since been used to treat patients with arthritis and other chronic degenerative diseases.
The U.S. Environmental Protection Agency (EPA) has designated copper as an antibacterial metal that suppresses infections such as E. coli, in-hospital infections, pneumonia, and allergies. The copper component is one of a group of metal elements essential for maintaining human life, containing about 1.4-2.1mg per 1kg of body weight, and is essential for normal metabolism and gene expression processes. However, because the body is unable to synthesize copper, the essential amount must be provided through diet. Deficiency of copper can lead to symptoms such as anemia, osteoporosis, low white blood cell count, immunity deficiency, and high cholesterol levels.
In this article, I'm going to cover the topic of Aerosilver. Aerosilver is an antimicrobial fiber developed by a company called “Hyosung,” and is the first Korean yarn maker to acquire the SF mark granted by FITI. The achievement of this SF mark certification is due to the amazing advantages of this fiber.
Hoops are the most difficult to choose among embroidery products. It's hard to tell what the product is like before using it. So, I've used almost everything I can buy on the market.
When starting a new hobby, or even after doing the hobby of a long time, many would always think about what sort of material they should buy. Because there are always so many options. And embroidery is probably the healthiest hobby that anyone can start with the least investment. But even so, it’s easy to be confused about which thread to buy, which embroidery hoop to get and what type of needle to use. And since most of don’t know these things very well when starting out, it’s daunting to know why a certain product is cheap or why another is expensive. Leaving us only more confused at the end of it, and sometimes because of this confusion we might say, “Let’s just give up.” Since you never know how long you’d enjoy the hobby, you usually have to always think long and hard before making a purchase.
I want to introduce a new mask filter that can be cleaned and reused a for a month. In Korea, there was a lot of demand for air filters because of the fine dust. Therefore, people not only used masks but also various filters, including window filters. Several companies have been developing and using nano filters since a few years ago, and began selling Nano filters that can be used in masks. This new nano filter was made by attaching nanofibers with a diameter of 100 to 500 nm to general fibers in a right angle or in a single direction.
