Abstract:
The invention relates to a method of premature wear of a fabric garment made of a colored denim canvas, wherein the aforementioned garment is placed into a rotating machine including a drum, characterized by the fact that the aforementioned method comprises a step during which the garment is rotated in the drum without being wetted or dampened, ozone gas being injected simultaneously into the interior of the aforementioned drum so as to bleach the aforementioned garment and give it a wear effect.
Abstract:
An inventive method includes the steps of: loading a fiber product in an appropriate form into a treatment vessel; wetting the fiber product; forcibly circulating an ozone-containing liquid in contact with the wetted fiber product to thereby bleach the fiber product; and forcibly circulating an ozone decomposing chemical agent liquid in contact with the ozone-treated fiber product to decompose ozone. This method ensures efficient bleaching of the fiber product with the ozone. Further, the method is advantageous in that the resulting bleached fiber product is less liable to be yellowed over time.
Abstract:
In an exposure apparatus of the invention, for a spatial light modulator, each of a plurality of pixel portions fewer than the total number of the pixel portions is controlled with a control signal generated according to exposure information. Namely, a part of the pixel portions is controlled without controlling a whole of the pixel portions on the substrate. Thus, the number of pixels in the pixel portions is decreased, and transfer time of the control signal becomes short. This enables modulation speed of the laser beam to be increased and the high-speed exposure to be performed. An incorporated laser light source, in which the laser beams are incorporated and struck on the optical fiber, is preferable to the laser device. By adopting the incorporated laser light source, high brightness and high output can be obtained, and it is preferable to the exposure of the spatial light modulator. Since the fiber array is obtained with few optical fibers, it is low cost. Since the number of optical fibers is few, the light-emitting region is further decreased when the optical fibers are arrayed.

Abstract:
This invention relates to a method for decolorizing a dyed denim fabric through a dry ozone process to obtain an aesthetically pleasing decolorized look or fashionably faded look in the denim fabric. The method comprises three dry ozone treatment processes used alone or in combination thereof. The first dry ozone treatment process includes wetting a denim textile product with water and oxidizing it with ozone. The second dry ozone treatment process includes spraying water to desired areas of the textile product and oxidizing it with ozone. The third dry ozone treatment process includes loading the denim textile product and wetted cotton fabric scraps into a drum, and oxidizing them with ozone.
Abstract:
The present invention relates to compositions comprising photosenitizer that can be used to provide lipophilic fluids with bleaching capabilities, lipophilic fluid cleaning compositions having bleaching capabilities and processes of making and using same. Such compositions provide the cleaning benefits of typical lipophilic solvents and additional cleaning benefits that include bleaching.
