The GUPPY FRIEND washing bag was developed with the concept of keeping the microfibers that fall out of laundry out of the river or sea as much as possible. The material used is polyamide resin (nylon).  You might think that, wait, if that's the case, isn't the microfiber flowing out of the bag itself? I think there are some people who feel that there are some contradiction.

So today we wanted to talk about the characteristics of the polyamide used in this bag, and what kind of usage will it be effective in? We'll also share our comments through using it in our daily lives.

First of all, what is polyamide? 

If you search on the internet, you will find out that polyamide = nylon. The name nylon is a trademark of DuPont, an American company, and is the first synthetic fiber in the world. Therefore, polyamide and nylon are both used as names, but understand that they are the same. There are several types of nylon, and the bamboo toothbrushes we sell in our store use a material called nylon 6 for the brush part. Also, in Europe, we see the name "polyamide" used compared to "nylon".

Now let's talk about the characteristics of polyamide (nylon). Polyamide resin is said to be thinner than spider's web, beautiful than silk, and stronger than steel. Therefore, it is possible to weave a fine fabric that is hard to see with the naked eye, and it has excellent strength that does not tear easily. 


GUPPY FRIEND washing bag has all of these characteristics. What kind of clothes are best to use with the bag to be effective when washing? Some of the items we recommend have something in common: synthetic fibers that are easily torn by rubbing, and brushed fabrics. For example, there are many familiar items that you are wearing, such as fleece and faux fur that you may use often in the fall and winter, and sweatshirts that uses brushed synthetic fibers in the inside. Let's take a fleece as an example; it is said that 2000 microfibers fall off after each wash.

When we compared the number of microfibers that would fall out of the fleece, and the number of microfibers that would have fallen out of this washing bag, we decided to wash using GUPPY FRIEND without hesitation, and has now become a staple item for us. 

The performance of sewage treatment in Japan seems to be good and highly evaluated, but there are still limits.

Which is why we don't want to rely too much on it and recommend that we all pay attention to the water drainage from laundry from your home!
