Delivering perfect sanforizing results

Introduction

Sanforizing is a mechanical finishing process used for cotton fabrics mainly and most textiles made from natural or chemical fibres, patented by Sanford Lockwood Cluett (1874–1968) in 1930. It is a method of stretching, shrinking and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrink- age which would otherwise occur after washing.

The cloth is continually fed into the sanforizing machine and therein moistened with either water or steam. A rotating cylinder presses a rubber sleeve against, heated, rotating cylinder. Thereby the sleeve briefly gets compressed and laterally expanded, afterwards relaxing to its normal thickness. The cloth to be treated is transported between rubber sleeve and heated cylinder and is forced to follow this brief compression and lateral expansion, and relaxation. It is thus shrunk. The greater the pressure applied to the rubber sleeve during the sanforizing process, the less shrinking will occur once the shirt is in use. The process may be repeated.

Chopra-Dhall Group is the world’s largest maker of compressive shrinking lines with over 2,000 installations across 25 countries over the past 50 years. Chopra-Dhall Group brings forth deep domain expertise and hands-on operational experience to deliver the best sanforizing results for the target application and fabric.
