Abstract

PROBLEM TO BE SOLVED: To obtain a synthetic leather that has soft fabric hand and shows excellent resistance to peeling after recurring extensions by forming a synthetic resin coating layer on at least one face of the base fabric made of poly(trimethylene terephthalate) fibers. SOLUTION: A base fabric is a woven, knitted or nonwoven fabric made of poly(trimethylene terephthalate) fibers with the total yarn fineness of 20-300 deniers and the filament fineness of 0.1-5 deniers and has a unit weight 50-200 g/m<2> . The base fabric is coated with a synthetic resin such as polyurethane by the dry or wet process to form a coating layer thereby producing the objective synthetic resin.

2. Description of the Related Art Conventionally, what is called synthetic leather is cow,
It is used to imitate natural leather such as horses and sheep.Synthetic leather is coated or laminated with a synthetic resin dissolved with a solvent on a fiber base fabric such as woven or knitted fabric using a dry method. There are known dry synthetic leather made by the above method and wet synthetic leather made by coating a synthetic resin dissolved by using a solvent on a fiber base fabric such as a woven fabric or a nonwoven fabric by a wet method.

[0003] Natural leather has a structure in which ultrafine collagen fibers are three-dimensionally entangled, and the density is coarser toward the inside and denser toward the surface, and the dense fiber layer on the surface is dyed with a dye. It is known that the material or pigment is colored. On the other hand, for example, wet synthetic leather is formed on a woven or non-woven fabric layer by applying a synthetic resin by a wet method to obtain elasticity and moisture permeability by a wet method, and further formed thereon. And three colored surface layers, which are fundamentally different from each other in terms of structure.

As described above, due to the difference in structure between synthetic leather and natural leather, there are many differences in their characteristics. The differences are strength, feel, feeling, moisture release, moisture absorption, coloring, weather resistance, stretchability, peel resistance, etc.
In particular, there is a specific problem regarding the peel resistance due to the structure of the synthetic leather. Strength, feel, feel, and peel resistance have been significantly improved as a result of studies such as improving the properties of synthetic resins, adjusting the thickness of the resin film, or adjusting the degree of penetration of the resin into the base layer. However, it is still not enough.
