Replace animal hides with microfiber leather
For a normal leather goods industry such as footwears, the quality criteria is decided by the physical, chemical criterias of component materials. To judge the compatibility of microfiber leather in the uppers and insole of shoes, we have conducted the scientific test on microfiber leather sample and cow leather to compare the result. The test involves 6 microfiber leather samples: 4 to make shoes upper, and 2 to make shoes insole; and 2 cow leather samples of 26 JSC - Ministry of Defenses: 1 to make shoes insole and 1 to make shoes upper. (table 1 and 3)
All the tests are conducted at the National Shoes and Leather Research Institute. Test results are shown in the below table 2 and 4: Microfiber leather's technical specifications are greater than that of cow leather and they are all greater than the criteria for shoes uppers and insoles production based on ISO/TR 20879: 2007 and ISO/TR 20882:2007.
The leather test sample is taken from the best quality area of the hide because the quality of the rests are not similar. A big difference between natural leather and microfiber leather is that microfiber leather has very balance quality amongst all leather pieces. Based on the above test results, microfiber leather shoes satisfy the criteria: high endurability, tidiness and comfortable. Breathability of microfiber leather is much greater than natural leather, and much higher than the standard requirement for shoes' tidiness (it can keep the feet dry and heat resistant). This is a major advantage of microfiber leather.
Each piece of natural leather has different and complicated from, it's not consistent amongst the hides. On the surface of natural hide there can be holes, flaws and each area has different quality and different colors. While using natural leather, the amount of wasted leather is large. In actual production, the are with good leather quality is about 55% of the hide, so, if a product of Leather for Belt requires more than 55% of the hide area, then it won't have a good output product.
The production efficiency of natural leather is lower than productivity. Based on the quality distribution on natural hide, the amount of usuable leather is about 60 to 80% only.
Microfiber leather is produced in roll form, stable quality amongst the whole roll, the cut productivity and efficiency is increased greatly and it reduced the amount of wasted leather. Therefore, the percentage of usable microfiber leather after cutting is accounted for 90%.
Cutting productivity: with natural leather, manufacturers need to cut each piece according to the marked map. As each piece of natural leather is unique, therefore, the cutting productivity is low.
With microfiber leather, the manufacturers can cut 6 to 10 layers at the same time using the same marked map. The preparation for cutting is simple, doesn't require many people. In comparison with natural leather, the cutting productivity of microfiber is 20 to 30 times faster.
The production cost of a leather good is built up with:
• Materials costs
• Labor cost
• Management cost
• Power cost (electricity, water)
• Other costs
When using microfiber leather, the above costs are lowered:
• Lower the material costs: microfiber leather is 30% cheaper than natural leather while productivity and production-efficiency is much higher.
• Reduce labor costs. The production stages are optimized, lesser labors, simple process.
• Decrease depreciation costs, save power cost.
• Decrease other costs, including waste resolving cost because wasted materials are decreased.
