What actually happens

A circular loom produces a seamless tube, which is why a woven sack has no side seams to fail. Weave density is counted as tapes per inch in each direction, and together with tape denier it determines fabric weight.

What to specify

Specify mesh (tapes/inch, warp × weft) alongside GSM. Two fabrics at the same GSM can behave differently.

How it goes wrong, and what catches it

The failure mode. Loose weave gives a bag that stretches and distorts when filled; leaking at the seams usually starts as a weave problem, not a sewing one.

The control. Mesh count verified against the specification on a cut sample; fabric weighed rather than assumed.
