Shrinkage Belt Illustration courtesy of Morrison Textile Machinery Inc. Shrinkage, also called Sanforization, was patented in the US in 1954. Today this process is an essential part of the finishing process for most fabrics. Like in all other pro cesses, also here the optimum result can only be reached when using the best equipment. Saurer has 55 years of experience in production of excellent shrinkage belts. Sanforizing is a method of shrinking and fixing the cloth in both length and width The shrinking process takes place between the shrinkage (rubber) belt and the heated cylinder. The pressure...

Shrinkage Belt The economics of a shrinkage belt To achieve the best price-perfor mance ratio for a belt, two factors are essential: efficient utilization of surface as well as a maximum lifetime of the belt. Belts all over the world are sold per unit length (US $ / inch). This means that finding the right belt width also means finding the optimum price and / or area usage. The smaller the difference between the overall belt width and the working face width, the more efficient the use of the belt. This difference is defined by the belt edge shape. The Saurer Daytex Curved Edge optimizes the area...

Shrinkage Belt Efficiency Dimensions 1 Steam cylinder width 2 Overall belt width 3 Working face width 4 Cloth width How to reach the required efficiency? –– ptimized area usage is dependent on finding the O optimum belt width. There are 2 belt widths to be considered: overall belt width and the working face width. –– Overall belt width should be at least 25 mm smaller than the steam cylinder or the shortest roller. –– orking face width of the belt should be at least 150 mm W wider than the fabric to be treated, but not longer than 200 mm.

Saurer Shrinkage Belt Temperature Each type of fabric needs a certain temperature for a good processing. In general the belt should operate at the lowest possible temperature to reduce the aging of the belt and premature cracking. The table below shows typical settings for different fabrics. Tension To ensure proper shrinkage of the fabric the rubber belts needs 2% of tension. Please refer to the technical information how to set up the right tension on the belt. The table below shows the recommended stretch according to the wall thickness of the belt.

The water sprays on the inside lubricates and cools the belt to reduce the friction with the rollers. The water on the outside cools the rubber belt to avoid overheating...
