chemically alters the surface to allow it to retain the laser formed image after washing the pretreatment that is used should preferably be liquid it should preferably remain bound to the fabric for either the life of the fabric or at least for a number of washing cycles of the fabric and it should at least in one embodiment have the function of at least one of wrinkle and or stain resistance a method comprising treating a fabric material with a treatment that remains bound to the fabric and is intended to change some characteristic of the fabric to make the fabric more resistant and using a laser to form a perceivable change to a color of the fabric without undesirably damaging the fabric although only a few embodiments have been disclosed in detail above other embodiments are possible and the inventor s intend these to be encompassed within this specification the specification describes specific examples to accomplish a more general goal that may be accomplished in another way this disclosure is intended to be exemplary and the claims are intended to cover any modification or alternative which might be predictable to a person having ordinary skill in the art for example other materials that is other than permafresh may be used an important part of the material is that it alters the characteristic of the fabric and in a specific way the fabric 39 s characteristic should be altered in a way that makes.
