The new suggested process is particularly useful in preparing fashion garments such as faded denim blue jeans, and the like, without the use of harsh chemical bleaches or the abrasive effects of stones, pumice, sand or the like.
The reducing agents are particularly effective where the sizing comprises a starch, starch derivative or a modified starch.
Denim blue jeans and jackets which have been faded, "stone-washed", ice washed, and/or sand blasted to produce a particular appearance are very popular. However, to produce the desired effect it has been necessary to utilize processes which cause substantial deterioration or degradation of the fabric. Bleaching solutions containing chlorine or actual pelleting of the garment with sand or stones to produce a fashion effect causes damage to the fabric which affects its wear life.
Special effects can also be achieved by selectively treating the garment with dyes having different degrees of reactivity. The non-reactive or lesser reactive dyes may be applied by spraying, brushing, dipping, or the like. In a similar manner reducing agents can then be applied.
The application of reducing agents to garments by stones soaked in these reagents also provides a means of modifying the color of the garments and of modifying the texture of the garment. The stones, such as pumice stones, that are ordinarily used in stone washing, can be soaked in a suitable solution and then tumbled with the garment. The areas which are touched by the stones would undergo greater decolorization so that a color differential would occur on the garment. The pattern and the decolorization differential may be varied by utilizing stones which have been treated with different types of reducing agents.
