Present inventor has found that at different temperature, the complexity of ink removal can be sent out in the course of the study
Raw certain variation, during stretching, surface molecular rearranges material under the conditions of external force, generates a large amount of thermal energy, when
Ambient temperature be 10-30 DEG C when, material surface temperature has been not up to softening temperature, surface still in solid states so that
Ink is detached from material surface, still separates with material after cooling, at this point, ink easily removes.
Inventor is under 10-30 DEG C of environment temperature, by the ratio for adjusting draw roll linear velocity and lay-on roll linear velocity
For 2-3, the material that can produce surrender and thin neck situation is stretched, the removal rate of ink reaches 99% or more, inventor
Think the reason is that under the above conditions, thin-film material surface generates a degree of deformation, when material reaches yield point, material
Rapid to generate plastic deformation, it is machine-direction oriented that progress occurs for interior molecules arrangement, and generates a large amount of heat, at this point, material is produced
Raw draft temperature is in material glass temperature hereinafter, material surface will not generate softening form, and ink and connection resin are still
In solid states, ink and material surface generate relative displacement, so that ink be made to be separated from from material surface.
In a preferred embodiment, environment temperature is 10-80 DEG C in the step (1).
In a preferred embodiment, thin-film material is selected from polystyrene, polymethylacrylic acid in the step (1)

One of or it is a variety of.
Present inventor has found in the course of the study, when environment temperature is greater than 30 DEG C, in above-mentioned same condition
Under, ink can not be completely removed in thin-film material surface, analysis principle, be due to material during stretching, in external force item
Part lower surface molecular rearrangement, generates a large amount of thermal energy, when ambient temperature increases, material surface temperature is caused to reach
Softening temperature, surface are in flow viscosity state, and ink still adheres on the surface of the material, and still adhere to material after cooling down, and lead to oil
Ink cannot be detached from, and therefore, inventor further optimizes the method.
In a preferred embodiment, component A is added during step (2) scrub.
