Notes from the sizing box

What to monitor on the loom, which readings point back to the size box, and how to separate a weaving fault from a sizing one.

The control points across a sizing run, the value to hold at each, and what drifting first tells you about the rest.

A working order of response when sizing defects appear: what to check, what to change, and what to leave alone.

What a yarn is, how count and twist describe it, and how its construction determines whether it survives the loom.

The checks that tell you a size run went right, from pickup and moisture to the first hour of loom data.

Not every warp needs sizing. Which yarn types do, which do not, and what decides it at the count and construction level.

What size pickup is, how it is measured and controlled, and why a percentage point either way shows up in loom efficiency.

Natural, regenerated and synthetic fibres compared on strength, moisture behaviour and what each one needs from a size.

The fabric families a weaving mill actually runs, what distinguishes each, and where sizing requirements change between them.
