Sanforizing

Sanforizing is a process that pre-shrinks woven fabrics to reduce residual shrinkage after garments are made. It works by passing cotton fabric over an elastic felt blanket, compressing the fabric and forcing it to conform to the blanket's shorter dimensions. This achieves controlled shrinkage. Residual shrinkage depends on fiber type, yarn construction, fabric weave, and number of wash cycles. Sanforizing stabilizes fabrics by stretching and shrinking them before cutting, reducing shrinkage that would otherwise occur after washing. It was patented in 1921 and became widely used, ensuring fabrics and garments maintain their dimensions during production and use.

Sanforizing:

Sanforizing is a controlled compressive shrinkage process, which is applied on woven fabric to achieve shrinkage before making the garments. After sanforizing the residual shrinkage of woven fabric may be zero. In sanforizing process shrinkage is achieve by passing the cotton fabric onto a movable elastic felt blanket is released it assumes a shortened conditional. Thus the cotton fabric is forced to conform this compression.

Residual Shrinkage:
Residual Shrinkage is the latent shrinkage of a fiber , ilament, yarn or fabric. The shrinkage amount of fabric is dependent on: !. The nature of fibers ". The character of threads #. The way of interlacing of thread in the fabric. $. Crimp in yarn. %. &ycle of washing no. of washing.

Sanforizing Process:
Sanforizing is a mechanical finishing process of treating te'tile fabrics to prevent the normal dimensional alternation of warp and weft. It is also called anti(shrinkage finishing process. It is a process of treatment used for cotton fabrics mainly and most te'tiles made from natural or chemical fibres, patented by Sanford )ockwood &luett *!+,$-!./+0 in !.#1. It is a method of stretching, shrinking and fi'ing the woven cloth in both length and width, before cutting and producing to reduce the shrinkage which would otherwise occur after washing .

Simplified diagram of the sanforizing method of producing shrinkage Sanforizing process is based on the principle that when a elastic felt blanket is passed around a metal roller in contact with it, its outer surface is process e'tended and the inner surface contracted. So the process is called controlled compressive shrinkage process. Read more2 http233te'tilelearner.blogspot.com3"1!"31"3sanforizinganti(shrinkage( finishing.html4i'zz"i5wTdArc

What does Sanforization mean?


The process of pre(shrinking a fabric so to a limit the residual or further shrinkage of the fabric to less than !6. This sanforization process involves the stretching of the fabric before it is washed, which helps to prevent shrinkage. abric that doesn7t undergo sanforization and is considered raw is likely to shrink up to !16 on the initial wash and continue to shrink up until the third wash. In the world of denim, un(sanforized denim is referred to as raw denim.

Sanforization is a process that stabilizes the fabric before it is cut by stretching and shrinking it. 8amed after its inventor, Sanford )ockwood &luett, it was patented in !.#1. In !.#/, 9lue 9ell *now :rangler0 began using the method for its Super 9ig 9en overalls. ;uring the sanforization process, the material is fed into a sanforizing machine and moistened with water or steam to promote shrinkage. It is then stretched through a series of rubber belts and cylinders before it is finally compacted to its final size. Sanforizing ensures that the fabric will not shrink during production or wear.
