1. An improved wet processing method for producing improved terry fabrics, the method comprising the steps of:
treating a woven fabric made from pile yarn based on an enzymatic treatment process, wherein the enzymatic treatment process comprises de-sizing the woven fabric using an optimized dosage of de-sizing ingredients, washing the de-sized woven fabric and bio-washing the washed woven fabric using optimized dosage of bio-washing ingredients;
pre-treating the enzyme treated woven fabric and subjecting the pre-treated woven fabric to a hot air beat-up process, wherein the hot air beat-up process comprises mechanically treating the pre-treated woven fabric in open-width in a textile tumbling machine with optimized hot air beat-up parameters, wherein air is blown onto the pre-treated woven fabric from both directions for a predetermined duration and at a predetermined frequency causing to and fro movement of the woven fabric in tumbling chambers of the tumbling machine resulting in an instantaneous impact produced on every pile loop of the pre-treated woven fabric such that built in stress within fibers and the pile loops is released and the fibers rearrange in a path of least resistance to produce a relaxed, open and aligned fiber structure in the woven fabric;
dyeing the mechanically treated hot air-beaten up woven fabric; and
finishing the dyed woven fabric, wherein the dyed woven fabric is dried and finished with a softener, and subjected to tumbling using optimized finishing parameters to obtain an improved terry fabric.
