Decoction fabric - one of the major steps in the manufacture of natural materials. This is a necessary process that helps to remove the remnants of fabric starch, nitrogen, pectin and zhirovoskovyh substances. Decoction carried out in special digesters. Before the process is applied to the fabric a special structure, which is based on sodium hydroxide. After impregnation, the fabric is compressed and fed to the boiler, which is installed on top of an airtight cover. Cooking liquor is gradually replacing the air from the boiler, because the presence of oxygen in the cooking unit may lead to a weakening of the fabric fibers. The process continues for 3-4 hours, after which the material is rinsed for BCF machine. After decoction tissue becomes softer, better water tight, but it has a bright gray color.
