The economic advantages of using casting paper to make artificial leather and synthetic leather are as follows:
1.Equipment cost is greatly reduced. This is because the casting coating method using casting paper is simpler than the casting coating method and calendering method of stainless steel strip in terms of equipment. In addition, release paper is much cheaper than stainless steel tape.
2.The casting paper can be used repeatedly. In foreign countries, it can be used repeatedly for 5 times to manufacture PVC artificial leather and 10 times to manufacture polyurethane synthetic leather. Of course, the number of repeated uses has a very important relationship with the production equipment, storage and operation level of artificial leather manufacturers.
3.It can change the surface of artificial leather or synthetic leather, which is impossible to do with stainless steel belt. The so-called “surface change” means that the embossed release paper can transfer various leather patterns to the surface of artificial leather or synthetic leather, and can modify the surface. In addition, it can make the surface have various luster, from matt, semi gloss to ultra-high gloss. Moreover, it is quite convenient to change the leather grain, without changing any equipment, just change a piece of release paper with the required leather grain.
4. It prevents adhesion of artificial leather or synthetic leather. The release paper is coated with polyvinyl chloride or polyurethane vinegar. After drying, it can be rolled up for storage and peeled off when needed. This is also impossible with other carriers.
5.Multilayer coating can be carried out on the same release paper.
6.For artificial leather or synthetic leather with different resin formulations, the peeling characteristics of release paper can be adjusted and controlled.
The important classification methods of artificial leather release paper are as follows:
A.According to the glossiness classification, it can be divided into highlight type, bright type, semi bright type, semi extinction type, extinction type and super extinction type;
B.According to the coating material, it can be divided into silicon based paper and non silicon based paper;
C.It can be divided into polyvinyl chloride (PVC) artificial leather paper and polyurethane leather paper according to the classification of use;
D.It can be divided into plain paper and embossed paper according to whether there are stripes or not.
