Abstract:

A denim fabric sheet is drawn into a folded rope configuration, and passed through an impact mechanism and an abrasion mechanism to give the fabric sheet a worn-out stonewashed appearance. Prior to passage through the impact mechanism the fabric sheet is coated with a water solution containing about five percent lubricant, four percent surfactant and about one percent antimigrant. After passage through the impact mechanism, the fabric sheet is rinsed and coated with a more dilute water solution about one percent lubricant, one quarter percent surfactant, about one half percent migrant, and about one half cellulase enzyme. The process is controllable to produce a consistent product appearance and fabric texture.
