US 12,071,722 B2 · Powder impregnation of textured fabric surfaces

Abstract

A textile fabric having increased improved surface properties, variously including surface stability, abrasion resistance, resistance to edge fraying, moisture control, and resistance to fluid penetration is created by introducing a plurality of particles including low-melting particles onto a top surface of the textile fabric. The top surface includes elevated areas, depressed areas, a plurality of surface fibers and gaps among the plurality the plurality of surface fibers. A desired pattern of particle deposition and depth of penetration from the top surface of the plurality of particles into the gaps is established, and heat is applied to the top surface to melt the low-melting particles deposited onto the surface.

Claims18

Dependent claims

A textile fabric comprising:

a plurality of yarns forming a top surface and a bottom surface of the textile fabric, wherein the plurality of yarns are looped together to form a plurality of elevated surface areas and a plurality of depressed surface areas along the top surface, the yarns comprising a yarn melting point and a plurality of fibers or filaments forming the yarns;
and
melted resin from a plurality of particles having a melting point lower than the yarn melting point,
wherein, within the elevated surface areas, a majority of the melted resin is located within the plurality of yarns and most of the melted resin is located under an exposed surface of yarns of the elevated surface areas.

1 more element

A method for improving surface and cut-edge stability of a textile fabric, the method comprising:

selecting a textile fabric comprising a plurality of yarns forming a top surface and a bottom surface of the textile fabric, wherein the plurality of yarns are looped together to form a plurality of elevated surface areas and a plurality of depressed surface areas along the top surface, the yarns comprising a yarn melting point and a plurality of fibers or filaments forming the yarns;
dispersing a plurality of particles on the textile fabric, the particles having a particle melting point lower than the yarn melting point;
causing at least a portion of the plurality of particles to enter the gaps among the fibers or filaments within the elevated areas of yarns on a top surface of the fabric and melting the plurality of particles in situ to create melted particle resin so that, within the elevated surface areas, a majority of the melted resin is located within the plurality of yarns and most of the melted resin is located under an exposed surface of yarns of the elevated areas.
