HOW TO IDENTIFY WARP AND WEFT DIRECTION OF A WOVEN FABRIC ?

HOW TO IDENTIFY WARP AND WEFT YARN DIRECTION OF A WOVEN FABRIC ?
IN WOVEN FABRIC CONSRUCTION TWO TYPES OF YARNS USE
THEY ARE WARP AND WEFT YARN. WARP AND WEFT YARN IS CALCULATED BY AN EPI & PPI TEST. FOR CALCULATING THAT WE HAVE TO IDENTIFY THE WARP & WEFT YARN IN A WOVEN FABRIC.
FOR THIS REASON, I HAVE SOME EXAMPLES TO IDENTIFY THE WARP & WEFT YARN OA A WOVEN FABRIC

WARP & WEFT YARN HAS SOME CHARACTERISTICS BY WHICH WAY WE CAN IDENTIFY THE WARP & WEFT YARN

THE SELVEDGE DIRECTION IS WARP DIRECTION
IN MOST CASES, EPI IS MORE THAN PPI
NORMALLY WARP COUNT IS FINER THAN WEFT COUNT
WARP YARN IS MORE TWISTED THAN WEFT YARN
NORMALLY REED MARKS APPEAR ON WOVEN FABRIC THAT IS WARP DIRECTION
IF ANY YARN CONTAINS ANY SIZING PARTICLES THEN THE SIZE YARN IS WARP YARN
