FLOCKED MATERIAL AND PROCESS TO PRODUCE IT

The present invention concerns a process for the preparation of a flocked material for coating surfaces and structures such as the interiors of automobiles, objects for interior decorating (walls, sofas, armchairs, etc.), handbags, suitcases or other accessories, covers or cases for weapons, musical instruments or electronic devices, or to make carpets and/or rugs, and that comprises the use of bicomponent fibres of the island-in-the-sea type of limited length (microfibres). The process of the invention comprises a step of partial and selective dissolution of the sea component by an alkaline removal agent, which makes it possible to obtain a flocked material characterized by improved resistance to abrasion and a more appealing appearance compared to flocked products of the prior art.

This disclosure relates to electromagnetic absorbing materials, and, more particularly, to a flocked carbon fiber composite material and methods for forming thereof. The flocked carbon fiber material comprises electrostatically applied carbon fibers, having a Z-plane component; electromagnetic modifiers; a substrate; a bonding agent; and an encapsulation agent. The method for forming said flocked carbon fiber composite material comprises preparing carbon fiber strands; separating carbon fiber strand clumps into carbon fiber strands; separating carbon fiber strands into carbon fibers; applying a bonding agent to a substrate; and electrostatically applying the carbon fibers to the substrate. The flocking device used to perform this method comprises an insulative section; a high voltage power source; a container attached to the insulative section; and a filtering section attached to the container.
