breaking length
The length of a strip of paper, cut either in the
machine or cross direction, or a strip of cloth,
cut either in the warp or filling direction which
would break of its own weight when suspended
vertically. It is a value calculated from the
tensile strength of the material. Under normal
circumstances paper will have a greater breaking
length in the machine direction than in the cross
direction, and cloth a greater breaking length in
the warp direction than in the filling. (42 , 98 , 341 )
