NANOFIBER FABRIC
20190352819 · 2019-11-21 · ·

A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.

Viscosity modified formaldehyde-free binder compositions and methods

Processes of making a non-woven glass fiber mat are described. The process may include forming an aqueous dispersion of fibers. The process may also include passing the dispersion through a mat forming screen to form a wet mat. The process may further include applying a carbohydrate binder composition to the wet mat to form a binder-containing wet mat. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The binder compositions may have a Brookfield viscosity of 7 to 50 centipoise at 20? C. The thickening agents may include modified celluloses such as hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and polysaccharides such as xanthan gum, guar gum, and starches. The process may include curing the binder-containing wet mat to form the non-woven glass fiber mat.
