Cellulose nanofibers (CNF), also called nanofibrillated cellulose (NFC), are nanosized cellulose fibrils with a high aspect ratio (length to width ratio). Typical fibril widths are 5–20 nanometers with a wide range of lengths, typically several micrometers .
Cellulose insulating material plants are used for the production of naturally insulating material out of raw material like newspapers, hemp, field grass and so forth.The insulating materials which are produced with this systems, are characterized by low energy input during the production compared to the conventional insulating materials such as mineral wool etc.
One small group of the numerous substances to be regulated by this act is carbon nanofibers (CNF). While still an active area of research, there have been studies conducted that indicate health risks associated with carbon nanotubes (CNT) and CNF that pose greater hazards than their bulk counterparts. One of the primary hazards of concern ...
The borates in cellulose insulation provide added control against mold. Installations have shown that even several months of water saturation and improper installation did not result in mold. [10] It is a common misconception that the mere presence of crude borates in cellulose insulation provides pest control properties to the product.
Wet-spray cellulose insulation is similar to loose-fill insulation, but is applied with a small quantity of water to help the cellulose bind to the inside of open wall cavities, and to make the cellulose more resistant to settling. Spray application provides even better protection against air infiltration and improves wall rigidity.
Sportswear textile with nanofiber membrane inside is based on the modern nanofiber technology where the core of the membrane consists of fibers with a diameter 1000× thinner than human hair. This extremely dense "sieve" with more than 2,5 billion of pores per square centimeter works much more efficiently with vapor removal and brings better ...
