Artificial leather sheet substrate and production method thereof |
摘要 |
<p>The artificial leather sheet substrates of the invention comprise a united laminate structure of a nonwoven fabric layer A and a knitted or woven fabric layer B and an elastic polymer C impregnated into the united laminate structure. The nonwoven fabric layer A and the knitted or woven fabric layer B are strongly bonded to each other by entanglement. A portion of the microfine fibers constituting the knitted or woven fabric layer B are exposed to the outer surface of the nonwoven fabric layer A. Therefore, the artificial leather sheet substrates exhibit excellent mechanical properties such as resistance to tear stress. Having a high density as compared with conventional artificial leathers, the artificial leather sheet substrates have feel and densified feel similar to those of natural leathers.</p> |
