Conventionally, polyurethane has been mainly used as a coating material or impregnation material in the production of synthetic leather. This is because the excellent elasticity and physical properties of polyurethane are suitable for synthetic leather materials.

General polyurethane synthetic leather is produced by polymerizing 20 to 80 parts by weight of a solid component obtained by polymerizing an urethane raw material polyol, chain extender and isocyanate in an organic solvent such as dimethylformamide or methyl ethyl ketone, and having a viscosity of 50,000 to 150,000 cps / 25 ° C polyurethane is used as impregnation material and coating material to produce synthetic leather, and there are dry method and wet method.

In the dry method, polyurethane is used as a coating layer and an adhesive layer, and a coating liquid containing polyurethane, dimethylformamide, methyl ethyl ketone and pigment in an appropriate ratio is coated at least once on the release paper, (A fabric, a non-woven fabric, or other fabric) is coated thereon by coating a coating solution prepared by blending a polyurethane adhesive, a curing agent, a curing accelerator, dimethylformamide and methyl ethyl ketone in an appropriate ratio, After the adhesive is sufficiently cured, the release paper is peeled off to produce a synthetic leather.

In the wet method, a fabric (nonwoven fabric, fabric) is impregnated with an impregnation solution containing an appropriate ratio of polyurethane, dimethylformamide and pigment, and then the impregnated fabric is coagulated in a coagulation bath in which water and dimethylformamide are mixed, Urethane, dimethylformamide, and pigment in an appropriate ratio is coated on a fabric impregnated with polyurethane, followed by coagulation in a coagulation bath in which water and dimethylformamide are mixed, drying in a water bath and a dryer, Synthetic leather is manufactured through post-processing (embossing, buffing, heat treatment, treatment, etc.).

However, in the case of synthetic leather produced in this way, environmental problems have arisen due to problems in the working environment caused by the use of the organic solvent and organic solvents remaining in the finished product of the synthetic leather.

Therefore, in recent years, a synthetic leather manufacturing technique using an aqueous dispersion type polyurethane which does not contain an organic solvent has been researched and developed. However, the difficulty in the manufacturing process such as processability and the economical efficiency for commercialization, And it was difficult to commercialize them.

Therefore, in order to solve the above-mentioned problems caused by using polyurethane as a impregnation material and a coating material in the case of a conventional synthetic leather, a new material is used as a impregnation material or a coating material so that there is no harmfulness in the production of synthetic leather, And has developed a synthetic leather manufacturing method having excellent physical properties such as solvent resistance, water resistance and stain resistance.
