Polyvinyl chloride synthetic leather without foaming structure and method for producing the same

A method for producing a polyvinyl chloride synthetic leather without a foaming structure, comprising processes of:

• providing a base fabric layer;
• and
• forming a top fabric layer on a side surface of the base fabric layer, wherein the top fabric layer is formed of a fabric composition;
• wherein, based on a total weight of the fabric composition being 100 parts by weight, the fabric composition contains:
• 25 parts by weight to 65 parts by weight of a polyvinyl chloride resin and 20 parts by weight to 60 parts by weight of a polymer plasticizer;
• wherein the polymer plasticizer is formed by a polycondensation reaction of a dibasic acid raw material and a diol raw material, and is end-capped by an end-capped fatty acid;
• wherein the end-capped fatty acid is a biomass derived fatty acid, a chemical structure of the end-capped fatty acid has a long carbon chain having a carbon number ranging from C8 to C22, an end of the long carbon chain has a carboxyl group, and another end of the long carbon chain does not have any carboxyl group;
• wherein a residual amount of the diol raw material in the polymer plasticizer is less than 300 parts per million (ppm), and an acid value of the polymer plasticizer is less than 1 mg KOH/g.
