impregnated fabrics
Fabrics in which the interstices between the yarns
are completely filled with the impregnating
compound throughout the thickness of the material,
as distinguished from sized or coated fabrics,
where the interstices are not completely filled.
Sometimes the reverse side of impregnated fabrics
are sized to insure the adhesive sticking to the
cloth. When a grain or pattern is applied to
impregnated fabrics, it is worked directly into
the cloth, rather than on a surface coating as is
the case of coated fabrics. See also: BOOK CLOTH . (208 , 260 , 341 )
