Method for marking and fading textiles with lasers
DCFirst Claim
1. A method for color fading, dyed textile materials with a laser, comprising the steps of:
- placing under a laser beam a dyed textile material; and
scanning the laser beam generated by the laser with a selected set of parameters to fade the dye of the textile material to replicate a uniformly faded textile or a stone washed, acid washed or acid ball washed textile.

Abstract
The present invention relates to an environmentally safe, water-free method for color fading and for producing patterns on textile materials (1, 10) by exposure to laser radiation (7, 12) of sufficient intensity to cause photo-decomposition of the coloring agent while leaving the underlying textile material undamaged. The pre-dyed material (1, 10), such as denim, is scanned by a laser beam (19, 20) generated by a selected laser having selective output characteristics to produce uniform fading and patterns of photo-bleached marks on the textile material (1, 10). When the laser radiation is modulated at a selected frequency, the fading may take the form of stone washing (18a and 18b), echo ball washing, or acid washing techniques commonly used on denim materials. The patterns (17a and 17b) may take the form of any desired image, line, or picture in the substrate material. For mass production the textile materials may be moved under the laser by a conveyer belt or similar means.

27. A method for fading textile materials treated with a dye, comprising the steps of:
-
(a) providing a source of laser radiation; and
,(b) irradiating the textile material with a laser beam scanned under preselected parameters for absorption by the dye to uniformly fade said dye. - View Dependent Claims (28, 29, 30, 31, 32, 33)
