Pretreatment of a fabric using a material that binds to the fabric and changes some characteristic of the fabric. In an embodiment, the characteristic that is changed can be at least one of stain and flash for wrinkle resistance. The material can be Permafresh material. The material can bind to the fabric, and intends to be maintained within the fabric for the life of the fabric. After pretreatment, the pretreated material is processed by a laser which intends to change the look of the material without undesirably damaging the material. The treatment may make the treatment by lasers more consistent and allow the lazed graphic to maintain its quality after repeated washings and wearing.

Surface pretreatment of fabrics for laser writing applications

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.

Laser scribing process to eliminate the denim enzyme by washing and laundry

A laser method scribes graphics on materials. The method relates to the identification and understanding of a new energy measurement called energy density per unit time, and the identification and simultaneous control of the laser operating parameters which influence this energy measurement. Once a range of energy density per unit time is determined for scribing a desired graphic on a given material, the energy density per unit time can be controlled to stay within that range to achieve desired results in a repeatable fashion. In a preferred embodiment, the invention relates to a method of scribing graphics on fabric, leather and vinyl materials. In this embodiment, the energy density per unit time can be controlled to substantially avoid complete carbonization, melting and/or burnthrough of the material.
