Effect of Resin Finish for Crinkle Appearance on Bending and Tensile Properties of Denim Fabrics

摘要

Crinkling or resin washing is one of the major dry process techniques that are done on almost all fashionable denim trousers. Generally crinkling means to form wrinkle in the specific position of the denim trouser by applying resin, then wrinkle formation and finally by curing. But resin changes the physical properties such as stiffness, weight loss due to abrasion, tensile strength etc. In this research work, four denim fabric of different GSM (gm/m~(2)) were taken and then resin was sprayed on them randomly as simulating the actual resin spraying process that is done for resin wash or crinkling process. Then different physical properties of those denim fabrics were measured. These physical parameters were evaluated by different tests specifically bending length measurement, tensile strength test etc. These tests result gives a clear concept that, after resin spraying denim fabric gets stiffer, harsh and abrasive, more brittle that may affect the durability of the life time of denim garments.
