A method and related apparatus for shrink-proofing a fabric, typically a knitted textile composed of interlocked loops of yarn made of natural and/or man-made fibers. The loops interlock along stitch rows that may become skewed. According to the invention the fabric is confined from expanding as it is delivered to and discharged from an in-line compression zone free of obstructions such as crimps, bends or kinks.
