fabrics. Descriptions of the defects, illustrations, and related
material are given under the most frequently used terms;

2. Terminology

2.1 Definitions:
abrasion mark, n—an area damaged by friction. (Syn. chafe
mark)
apron mark—See decorating mark.
baggy cloth—See wavy cloth.
baggy selvage—See slack selvage.
balling up—See fuzz ball.
barré, n—an unintentional, repetitive visual pattern of continuous bars and stripes usually parallel to the filling of
woven fabric or to the courses of circular knit fabric.
(Compare warp streak, mixed filling)
DISCUSSION—The term “barré” is sometimes used as a synonym for
“warp streaks” in warp knit and woven fabrics. Barré can be caused by
physical, optical, or dye differences in the yarns, geometric differences
in the fabric structure, or by any combination of these differences.
beaded selvage—See loopy selvage.
bias—See skew.
birdseye, n—in knitted fabrics, an unintentional tuck stitch.
blanket mark—See sanforizing mark.
