What Is Microfiber Leather

Microfiber leather is an abbreviation of ultrafine fiber PU synthetic leather. It is a non-woven fabric made of three-dimensional structure network by carding acupuncture with microfiber staple fiber. After wet processing, PU resin impregnation, alkali reduction, and dermabrasion and polishing And other processes eventually make microfiber leather. It is made by adding ultra-fine fiber to PU polyurethane, which makes the toughness, air permeability and abrasion resistance further strengthened; it has extremely excellent abrasion resistance, excellent cold resistance, breathability, and aging resistance. Eco-friendly, Comprehensive performance beyond real leather. Widely used for automotive, garment, bags, sofa, shoes, boots, basketball, belt, jewellery box and so on. We are specialize in microfiber leather production manufacture.We provide the optimal leather options, the best leather substitute and best leather alternatives for automotive seat covers and interiors, furniture & sofa upholstery, footwear and shoes, bags, garments, gloves, balls, etc.

While synthetic leather were once considered not suitable for high quality shoes,  PU microfiber leather has changed how shoes are made.

Microfiber leather is designed to hold up against weather conditions and the wear and tear of walking and running over an extended period of time.

They can retain their form very well, and thus are usually very durable if cared for properly. They're also more water-resistant and lighter than real leather, making them great for long wear and outdoor activities.

We found this video, below, that tests how durable shoes made with suede microfiber leather are. Check it out!

Microfiber leather, or micro fiber leather, is the highest quality grade synthetic leather (faux leather or PU leather), a high-tech simulation of high-end leather material. WINIW Microfiber Leather is simulated the structure of natural leather, using sea-island superfine micro fiber (ultra-fine fiber bundle), and high-grade polyurethane resins as raw materials, using needle punched nonwoven technology of 3D structure, has a lot of similar characters as natural leather, however better physical & chemical performance, has been widely popular around the world. Because of superior performance, WINIW microfiber synthetic leather has been the best leather alternatives and the optimal leather substitute, material, best vegan leather and eco leather, can replace natural leather perfectly!

Compared to natural leather, microfiber synthetic leather has many excellent qualities, such as chemical resistance and physical and mechanical properties. However, preparation of microfiber synthetic leather with a high water vapor transmission rate (WVT), moisture absorption and wearing comfort property is still a challenge. In this study, we prepared thermoplastic polyurethane (TPU)/sulfonated polysulfone (SPSf) electrospun nanofibers and applied them to a microfiber synthetic leather base (MSLB). The effects of TPU/SPSf nanofiber content on the structure and properties of the MSLB were investigated. The results indicated that the TPU/SPSf nanofibers with an average diameter of 0.12 µm were well distributed at all directions in the MSLB. Differential scanning calorimetry analysis showed four Tg peaks, further demonstrating the existence of TPU/SPSf nanofibers. With the increase of TPU/SPSf nanofiber content from 0 to 30 wt%, the contact angles decreased gradually from 111.64° to 67.07°, leading to 55.19% improvement in the WVT value (from 2868.96 to 4452.24 g/(m2•24 h)) and 26.25% improvement in the moisture absorption (from 628.70% to 793.75% mm/s). Simultaneously, when the nanofiber content was 30 wt%, the nanofibers tended to bundle and 6.79% decrement of air permeability was observed. Specifically, the softness of the MSLB was improved by 88.55%. Moreover, the thermal stability and the tear strength were also obviously enhanced. Consequently, this research provided a feasible and promising way to prepare a high-performance MSLB using TPU/SPSf nanofibers.

The difficulty in dyeing microfiber base filled with ordinary polyurethane presents a significant challenge in maintaining the uniformity and highly realistic appearance of the resulting products. In the present study, a type of acid-dyeable polyurethane (PU-MDEA; MDEA=N-methyldiethanolamine) was synthesized, and its chemical structure and dyeing properties were investigated. Nuclear magnetic resonance analysis indicated that cationic groups were successfully incorporated into the PU-MDEA backbone via chain extension using MDEA. The amorphous nature of PU-MDEA was determined by differential scanning calorimetry, X-ray diffraction, and polarizing optical microscopy. Owing to the strong binding between these cationic groups and acid dye, as well as the reduced resistance to dye penetration, PU-MDEA showed better dyeability toward the acid dyes studied herein when compared with the control sample (microfiber synthetic leather filled with ordinary polyurethane). The adsorption isotherm experiment revealed that the dyeing process conformed to the Langmuir model, thereby indicating that the acid dyes attached to PU-MDEA via strong ionic bonding rather than van der Waals forces or hydrogen bonding. Additionally, it was found that the wastewater resulting from the dyeing of the microfiber synthetic leather filled with PU-MDEA exhibited environmentally friendly characteristics when compared with that displayed by the control sample (microfiber synthetic leather filled with ordinary polyurethane). Thus, the current results show the potential of PU-MDEA, as a filler, in the manufacture of microfiber synthetic leather to achieve fast dyeing rate, high dye uptake, and good color fastness, thereby improving the uniformity and highly realistic appearance of the resulting products.
