Textile materials can be dyed at any stage of their production procedure. The main types of methods are batch, continuous, or semicontinuous processes. The method used depends on several factors including type of material (fiber, yarn, fabric, garment)
             type of fibers composing the material, end use of material, and the quality expected from finished product. The machinery used for dyeing application is usually made out of type 316 stainless steel. This strong material is used because of the constant
             ttack by the acids, bases, and other additional strong chemicals and dyes used in the process. Many fabrics also undergo printing processes to produce patterned effects.
             Batch dyeing is the most common method used today. In this system, textile products are processed as individual discrete units. The dye is transferred slowly to the material from a large volume dye bath. Three basic types of application are used 1)
             bric is circulated through a still dyebath 2) dyebath is circulated through a material that is held stationary 3) both the dyebath and material are circulated. The most popular machines that carry out batch dyeing are becks, jet dyeing, and jigs.
             Dyeing becks consist of a trough with a slanted back to allow fabric to slide down into the dye. The fabric has been sewn together at the ends to form a loop approximately 50 to 100 meters long. It is controlled by a reel that pulls the fabric out of
             he dye bath and over an idle roll that functions to press off excess dye. The chemicals used are added to the beck by a compartment in the front that contains a perforated divider that serves to let the chemicals be added gradually. The compartment is
             ated with steam to allow better mixing and provide agitation. The advantages of the dye becks are low cost, versatility, and the encouragement of yarn crimp and fabric bulk. The drawbacks are the amounts of water, chemicals, and energy used, and the pr
