Sanforization

A 1948 advertisement for sanforized cotton fabric

Sanforization is a treatment process, mainly applied to cotton fabrics and textiles made from natural or chemical fibres, patented by Sanford Lockwood Cluett (1874–1968) in 1930.[1] It is a method of stretching, shrinking and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrinkage which would otherwise occur after washing.

Process

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 another, 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 sanforization, the less shrinking will occur once the garment is in use. The process may be repeated.

The aim of the process is a cloth which does not shrink significantly during production, cutting, ironing, sewing or, especially, by wearing and washing the finished clothes. Cloth and articles made from it may be labelled to have a specific shrink-proof value (if pre-shrunk), e.g., of under 1%.

Applications

Karate gis (traditional Japanese karate uniforms) are often made from Sanforized cotton so that shrinkage does not occur with this heavy material. Karate uniforms are often of 10, 12, 14, or 16 ounces per yard (310, 370, 430, or 500 g/m) cotton so shrinkage can be quite severe after washing and drying. Sanforized gis are typically labelled as pre-shrunk. Fencers' protective jackets are usually made of unsanforized cotton canvas.

Text Appearing Before Image:
But hold the pen, the verbal poison and the unhappy messages (unless, of course, you've really behaved badly and want to apologize) when you're "mad" at any boy. A one-sided letter filled with "how dare you do this to me" phrases is no way to talk over a misunderstanding! Nine times out of ten, a gal doesn't mean it when she says "I never want to see you again," but how can a fellow find that out when he's too hurt to call again? Most boys think of girls as "sugar and spice and a lot of Friday-night fun," but a harsh, scolding letter can spoil that picture faster than you think. So don't say anything on paper you wouldn't say in person, for once that letter is in the mailbox, those little men in gray uniforms just won't give it back again! LADIES' HOME JOURNAL 29
Text Appearing Within Image:
Knockout on Sunday... Washout on Monday! What a difference a day makes (wash-day, that is)...to SOME cotton dresses. But a dress with "Sanforized" on the label can't lose its style to shrinkage, wash it as you will! So never let a cotton dress enter your life without the "Sanforized" trade-mark. Whether you're paying $3 or $30, look for that word "Sanforized" on the label every time! The style will never shrink away from the dress with "Sanforized" on the label! •SANFORIZED• TRADE ® MARK
Text Appearing After Image:
Cluett, Peabody & Co., Inc. permits use of its trade-mark "Sanforized," adopted in 1930, only on fabrics which meet this company's rigid shrinkage requirements. Fabrics bearing the trade-mark "Sanforized" will not shrink more than 1% by the Government's standard test.
