Notes from the sizing box

Staple spun against continuous filament: hairiness, strength, handle, and the very different sizing each one calls for.

How the two constructions differ in structure, stretch and end use, and why only one of them needs the warp sized.

The defects that show up after the size box, what causes each one, and the parameter to move first when you see it.

PVA, native starch and the PVA starch blend compared on film strength, abrasion resistance, desizing behaviour and effluent COD.

A multi component recipe against one cooked compound: recipe complexity, pickup consistency, desizing load and what changes in the kitchen.

Shuttle, projectile, rapier, air jet and water jet looms compared on speed, warp tension and the size film each one demands.

Carded, combed, open end, filament and blended yarns, what distinguishes each, and which of them have to be sized.

Single and multi cylinder sizing ranges compared on pickup control, drying and throughput, with the machinery makers mills actually buy from.
