Description
Technical field
The present invention relates to a kind of manufacture technology field of synthetic leather, more particularly to a kind of pattern by transfer membrane is transferred to
Transfer method on synthetic leather.
Background technology
The similar corium performance that synthetic leather is made up of synthetic leather base cloth, adhesive layer and surface layer resin it is high-grade artificial synthesized
Leather.Certainly, synthetic leather base cloth has many excellent performances, such as good ventilative and hygroscopicity, excellent physicochemical property,
Such as pulling force, tear resistance, these physical property are already higher than corium, but synthetic leather base cloth is Yi Dan carrying out after the laminating process of surface, first
The performance of first air-moisture-permeable just exhausts, secondly because of surface layer and synthetic leather bass integraty is bad causes surface plastic cement sense to be compared
Weight.To find out its cause, mainly traditional attaching process is to use common PU resins, PU resin good film-forming properties are airtight not inhale
It is wet, cause the intrinsic ventilative and hygroscopicity of synthetic leather base cloth to have no value, existing synthetic leather surface pattern or pattern into
Type technique is that the decorative pattern for leaning on release liners is posted, i.e., the chromatic pattern in release liners is directly bonded on finished product synthetic leather,
Pattern in release liners can not be combined well with synthetic leather surface, with reference to when lines it is very not three-dimensional, pattern directly floats over conjunction
Finished leather surface, it is difficult to which compared with corium, not enough, plastic cement sense is heavier, and Surface feel and corium ratio also have one for lines sophistication
Determine gap.
