Background technology
Leather as dress material is divided into artificial leather and natural leather.Itself can be used as commodity natural leather, also can be used as commodity with colouring leather by dyeing.Yet it is very expensive that natural leather is compared with dermatine.Thereby the product of dermatine manufacturing is developed as the substitute of natural leather actively.
Routinely, polyurethane artificial leather is by depositing polyurethane, using that oil-based adhesives is bonding with polyurethane-depositlayer and coarse cloth, print color prepares then on the barrier paper with formation stamp thereon.
The conventional preparation process of polyurethane artificial leather can followingly be described in detail.
At first, liquid polyurethane is deposited on the barrier paper with formation stamp thereon, and places thermal chamber under 100～130 ℃ temperature dry one minute.Then, oil-based adhesives is placed on the relative one side of the another side with having formation stamp thereon of polyurethane-depositlayer, in thermal chamber under 100 ℃ dry one minute more then.
Then, the coarse cloth of fibre fractionation is bonded on the binder deposition layer, and in thermal chamber 120 ℃ dry one minute down, then in curing chamber about 80 ℃ of following slakings 24～48 hours.Barrier paper is removed then, and prints on polyurethane-depositlayer.For the situation of using two kinds of different colours, above process and printing carry out twice by the same way, and the top printed layers finally is formed on the polyurethane-depositlayer.
