Abstract
A system of forming simulated seam abrasion on denim materials. The simulated seam abrasion is formed by using a laser beam to form a seam abrasion type pattern on the material. The pattem is like a ladder with uneven rungs. After the pattern is formed, the material is washed to better simulate real seam abrasion.
Claims8
A method of processing a textile material, cornprising:
- placing a material on a conveyer which passes a plurality of processing stations;
- at one of said processing stations, using a laser to scribe a plurality of lines on said material at a specific energy density per unit time;
- and
- at another of said stations along said conveyer, that is passed after said one processing station, washing said material.
1 more element
A method of processing a denim material, comprising:
- determining a desired energy density per unit time to use in a laser for scribing the denim material;
- using substantially half the determined energy density per unit time for a first pass, and then using the same half the energy density per unit time for another pass.
