What is Fuji City CNF Brand Certification?
This is a system under which Fuji City certifies products produced, manufactured, or processed using cellulose nanofiber (CNF), a new plant-derived material, or related technologies, as a brand.
The purpose of this program is to evaluate the quality of products and the technical capabilities of local industries, and to support the establishment of brands and the expansion of sales channels.

Sheet form
-
Rolled paper form
The blending ratio of cellulose and synthetic fibers can be freely adjusted, allowing for unique blending according to the application.
Also, depending on the types of synthetic fibers combined (polypropylene, nylon, polyethylene, etc.), composite materials with different properties can be produced.
In addition, in the production of cellulose and synthetic resin composites, by mixing cellulose and synthetic fibers into sheets,
it is easier to uniformly disperse cellulose in the composite and maintain stable quality.
By selecting the CNF/MFC blending ratio and fiber degree and blending according to requirements,
water resistance, chemical resistance, and other functionalities can also be added based on the synthetic fibers types.

Case studies of development and uses with expected applications
Development case study
Shizuoka Prefecture emergency medical gowns
The COVID-19 Pandemic caused a shortage of gowns at medical facilities in Shizuoka Prefecture.
In order to establish a production system in the prefecture, TENTOK developed and provided fabrics.
Fabrics made solely from synthetic fibers tend to have low tear strength, so there is a risk of tearing during sewing or use!
→The tearing strength is approximately doubled by blending MFC.
