ELIMINATION OF ODOR CAUSED BY LASER-ETCHING LEATHER
Systems and methods for the elimination of odor caused by burned or laser-etching leather are provided. One method comprises the steps of providing a leather article with a burned-odor characteristic by laser-treating a side of the leather article; and treating the side of the leather article with an odor absorbent comprising zinc ricinoleate to eliminate the burned-odor characteristic.
1 . A method for producing a burned article with a reduced odor, the method comprising:
producing a leather article with a burned-odor characteristic by laser-treating a side of the leather article; and
treating the side of the leather article with an odor absorbent comprising zinc ricinoleate to eliminate the burned-odor characteristic.
2 . The method of claim 1 , further comprising treating a second side of the leather article with an odor absorbent comprising zinc ricinoleate to eliminate the burned-odor characteristic.
3 . The method of claim 1 , further comprising heating the leather article to further eliminate the burned-odor characteristic.
4 . The method of claim 1 , wherein laser-treating the article comprises marking the surface of the article with a laser.
5 . The method of claim 1 , wherein laser-treating the article comprises modifying the depth of the article with a laser.
6 . The method of claim 5 , wherein laser-treating the article comprises laser-perforating the article.
7 . The method of claim 1 , wherein treating the side of the leather article with an odor absorbent comprises spraying the side of the leather article with an odor absorbent.
8 . The method of claim 1 , wherein zinc ricinoleate comprises 0.1 to 60 percent of the odor absorbent by weight.
9 . The method of claim 8 , wherein zinc ricinoleate comprises 2 to 20 percent of the odor absorbent by weight.
10 . The method of claim 1 , wherein the odor absorbent further comprises sodium iminodisuccinate and water.
11 . The method of claim 10 , wherein sodium iminodisuccinate comprises 1 to 30 percent of the odor absorbent by weight.
12 . The method of claim 11 , wherein sodium iminodisuccinate comprises 2 to 10 percent of the odor absorbent by weight.
13 . A burned article with a reduced burned-odor characteristic, the article comprising:
a laser-treated leather article treated with an odor absorbent comprising zincricinoleate.
14 . The article of claim 13 , wherein the laser-treated leather article comprises an article laser-marked on a surface of the article.
15 . The article of claim 13 , wherein the laser-treated leather article comprises a laser-perforated article.
16 . The article of claim 13 , wherein the laser-treated leather article is heat-treated.
17 . The article of claim 13 , wherein zinc ricinoleate comprises 2 to 20 percent of the odor absorbent by weight.
18 . The article of claim 13 , wherein the odor absorbent further comprises sodium iminodisuccinate and water.
19 . A system for producing a laser-treated article with a reduced-odor, the system comprising:
a conveyor belt;
a first station comprising a laser for producing a leather article with a burned-odor characteristic by laser-treating a side of the leather article; and
a second station comprising an odor-absorbent applicator for spraying the laser-treating side of the leather article with an odor absorbent comprising zinc ricinoleate to eliminate the burned-odor characteristic,
wherein the conveyor belt moves the leather article to the first station and from the first station to the second station.
20 . The system of claim 19 , further comprising:
a third station comprising a heating station for heat-treating the leather article to further eliminate the burned odor characteristic.
