Process Flow Of Super Fiber Suede Leather

The process flow of microfiber suede leather for automotive seats is as follows: COPET/PET fiber spinning → needle punched nonwoven fabric → resin impregnation → solidification and drying → reduced fiber opening → water washing → drying and setting → buffing → dyeing → finishing → final inspection → packaging and warehousing.

From the above production process of microfiber suede leather, it can be seen that there are many processes involved in the manufacturing of microfiber suede leather, including chemical fiber manufacturing, needle punched nonwoven processing, chemical engineering, and finishing. Among them, fiber manufacturing, needle punched nonwoven processing, and reduced fiber opening are very important. A good spinning process for microfiber suede leather can ensure that there is no island merging in the production process of island fibers, thereby ensuring that PET island phase fibers are opened. The process requirements for needled nonwoven fabrics for microfiber suede leather are also very strict. Not only is the fabric surface of microfiber suede leather required to be flat and uniform in density, meeting the requirements for conventional leather substrates, but also the fabric density is required to be higher. In addition, the appearance of the fabric should not have pinhole marks, and the fiber state structure within the needled fabric should be mostly in a straight line state.
