Microfiber leather has became more and more popular in the market, which means more customers interested in this material and more quantity poured into the leather market. However, microfiber leather is not as simple as normal PU leather. People who just starting to learn the microfiber leather maybe confused about some basic ‘names’ of microfiber leather. For example, regular microfiber leather (or figured sea-island microfiber leather), irregular microfiber leather(or un-figured sea-island microfiber leather). What exactly do they mean?

In order to make these things clear, we will start from the fiber:

  1. Cross section picture of one Fiber:

Regular fiber or figured sea-island microfiber means the island fiber is with regular shape, regular quantity and regular position, which means it can be controlled in the production.

Irregular fiber or un-figured sea-island microfiber means the different quantity, shape and position in one big fiber, and all of these characteristics such as quantity, shape, position cannot be controlled in spinning.

Data of difference as follows:

*Continuity of fiber means the length of one regular fiber is fixed, for example 5.0mm, and it’s without broken in the length direction. But irregular fiber is broken in several places in the length direction, and the broken is also random, maybe for one fiber is 2 broken, but the other one is 3 broken, and it cannot be controlled.

*Ratio surface or specific area of regular microfiber is fixed because of fixed number of islands, but it’s also random of Irregular fiber, and as much more islands in the irregular fiber, the ratio surface is much bigger than regular microfiber.

*To recycle COPET of regular fiber is not valuable, it costs more than the value of COPET. PE in the irregular fiber can be recycled. As a result, the cost of regular fiber is higher.

3. The microfiber leather contains fiber and PU. Because of the difference between the structures of fiber, the leather also becomes different. Leather material differences are as follows:

4. Specialty of two different types microfiber leather:

5. Environment protection:

6. Cost:

Because of the un-recyclable COPET and higher percentage of PA6 used in regular microfiber leather, the total cost of raw material is much higher than irregular microfiber leather.

In conclusion, people need to know the specialty of microfiber leather to use them in a appropriate way. For more information, please contact us for details.
