Sag resistant, formaldehyde-free coated fibrous substrate

Номер: US20120156471A1
Автор: Kenneth G. Caidwell, Lida Lu
Принадлежит: Individual

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

Specifically, it is well known to extract inks, dyes and pigments from various natural materials, such as minerals, plants and animals. For example, it was well-known around the Mediterranean region since at least the 15century B.C.E. that a purple pigment could be extracted from a sea snail called the spiny dye-murex and utilized to color fabrics. Over the years, many different natural and man-made materials have been utilized to create colored inks, dyes and pigments.In the modern era, many products are made from polymeric materials and are often colored using dyes and pigments. It is also generally known to utilize polymers that themselves exhibit a color, although it has been generally easier to simply color polymers using dyes and pigments.

A method for high rate assembly of nanoelements into two-dimensional void patterns on a non-conductive substrate surface utilizes an applied electric field to stabilize against forces resulting from pulling the substrate through the surface of a nanoelement suspension. The electric field contours emanating from a conductive layer in the substrate, covered by an insulating layer, are modified by a patterned photoresist layer, resulting in an increased driving force for nanoelements to migrate from a liquid suspension to voids on a patterned substrate having a non-conductive surface. The method can be used for the production of microscale and nanoscale circuits, sensors, and other electronic devices. 1. A device for assembling nanoelements , the device comprising a container for a suspension of nanoelements , a counter electrode disposed within the container , and a movable platform adapted for mounting a patterned substrate , the movable platform attached to a drive capable of pulling the platform through a surface of the suspension at a speed adjustable from about 0.5 to about 10 mm/min.2.
