Effects of Dry Washing Process on Denim Garment

Denim garment is most widely used due to its appearance, comfort, strength, durability and low cost, which gives the customers utmost satisfaction. Denim garment does not inherit customer’s desired properties in the primary stage of manufacturing, but can be incorporated desirably by applying some finishing treatment, most widely known as dry washing process, in the denim garment. The most widely used dry washing processes for denim garment to develop new a look and effect are hand brush, destroy, tagging, pressing crinkle, whiskering and PP spray. We applied a combination of dry washing process on raw sample to develop certain effect in the denim and measured the change of physical properties due to application of different dry washing process. First, a combination of dry washing process (certain number) is applied on raw sample and repeated on other four similar raw samples. Similarly other five combination of dry washing process, are applied on raw samples. Due to the application of these combinations of dry washing process on raw samples, they undergo changes of some physical properties like GSM, tear strength and EPI & PPI. Then the average values of these properties (GSM, tear strength and EPI & PPI) for repeated application of combination of dry washing process on similar raw samples are calculated. Then the difference between the average value and the raw value of specific properties is calculated to show the deviation due to the application of combination of dry washing process. This gives an indication of change of physical properties due to application of different dry washing processes for imparting desired effect on denim garments.
