In 80’s we have seen Resin being used to give non press , iron free trousers & now we are using in Denims to make wrinkles & creases to look natural vintage which stays after multiple home laundries.
The present invention relates to processes and methods for treating Denim garments. In particular, the invention relates to the treatment of denim made of cotton, cotton blends and synthetic fabrics for the purpose of imparting no press properties thereto.
Typical Resin treatment process for Non denim garments for Durable Press finish:
Lets talk about wrinkle free, durable press or crease free finish on non denim trousers. A variety of techniques and additives have been suggested for use in the treatment of cotton fabrics to obtain durable press properties. A typical process suggests the use of a low-formaldehyde glyoxal resin (10%), a non-ionic wetting agent (0.2%), an amino functional silicone (3%), a polyethylene emulsion (2%), and acetic acid to maintain pH in aqueous solution wherein water comprises the remaining 84%. Then load the machine with the garments prior to the addition of the liquid mix components. Once the mixture components are added, the garments be allowed to soak for between six and ten minutes without agitation. The offload & do hydro extract & semi dry.
The amount of time required to reach the target moisture level will depend on the weight of the fabric, the temperature of the dryer, the duration of the drying cycle, and the extent to which the garments are tumbled. However, it is important to keep the drying temperature below a temperature which will cause the resin to set.
Once the garments have been dried to the proper moisture level, they are ready for the pressing and final cure steps. It is important to press and finally cure the garments without substantial delay, i.e. delay of more than approximately 12 to 24 hours, depending upon the weight of the fabric comprising the garments. Denim fabrics can be held between the drying and the pressing steps longer than lighter weight fabrics, because they tend to more readily retain moisture. Pressing of the garments in accordance with the present invention is done with a garment press capable of exerting a vacuum on the garment through the lower plate of the press. Initially, the garments are positioned with the aid of a vacuum to eliminate wrinkles and they are subsequently subjected to a steam treatment for approximately five seconds with the vacuum turned off. Steam is then applied to the garment through the top plate of the press for approximately 5 seconds. Finally, the garments be pressed for non denim to get wrinkle free, durable press finish or crunched for denim where ever 3D effect needed and cured.
The current technology of post cure being introduced for non denim garments process gives an option to produce a garment with smooth drying and wrinkle resistant properties along with sharp creases that are durable for the life of the garment. In this process the resin is padded onto the fabric and dried at low temperature. The fabric is then cut, garment constructed and creases pressed into the garment. A high temperature cure in this configuration is given to cross-link the resin. This process, though giving excellent results, has not been too successful with garment manufacturers owing to obvious limitations of colors, styles and fabric weight, and the need for a direct interface between mills, garment manufacturers and retailers.
