<p>The hygienic performance of <a href="https://www.boseleather.com/pvc-artificial-leather" target="_blank">PVC</a> <a href="https://www.boseleather.com/pvc-artificial-leather" target="_blank">artificial</a><a href="https://www.boseleather.com/pvc-artificial-leather" target="_blank"> leather </a>is simply the air permeability and water vapor permeability of PVC artificial leather. Due to the small artificial fiber bundles, they are quite strong and breathable.</p><p> 1. Air permeability: Air permeability refers to the amount of air per unit area of artificial leather under a certain pressure and a certain time. The permeability of various PVC artificial leathers is quite different. The textile and loosening of the fibrous structure of the PVC artificial leather itself and the performance and thickness of the coating layer are decisive for its breath-ability. Generally speaking, painted PVC artificial leather is less breathable than unpainted PVC artificial leather, and the thicker the coating layer is, the worse the breath-ability is; suede leather is more breathable than full-grain leather (leather that retains the surface of PVC <a href="https://www.boseleather.com/pvc-artificial-leather" rel="noopener noreferrer" target="_blank">artificial </a>leather). </p><p> 2. Water vapor permeability: The water vapor permeability of PVC artificial leather, also known as moisture absorption and dehumidification, means that PVC artificial leather can make the water vapor from the air on the side with higher humidity to the air on the side with lower temperature through the PVC artificial leather. Performance. The water vapor permeability of PVC artificial leather depends on its permeability, and it is also affected by the ability of PVC artificial leather to absorb moisture. Because PVC artificial leather has good water vapor permeability, the perspiration when people wear PVC artificial leather products can be smoothly discharged into the air, making people feel that wearing PVC artificial leather products is much more comfortable than artificial <a href="https://www.boseleather.com/pvc-artificial-leather" rel="noopener noreferrer" target="_blank">leather</a>.</p><p> Fastness is an important sign of the inherent quality of artificial leather. In order to fully reflect the fastness properties of artificial leather, the fastness of artificial leather is divided into the following types:</p><p> 1. Tensile strength: It refers to the maximum breaking load force that the unit cross section of PVC artificial leather can withstand. This index is one of the important indicators of the fastness of the surface PVC artificial leather. In other words, the tensile strength is the strength of the PVC artificial leather.</p><p> 2. Tear strength: refers to the maximum load that can be sustained by the PVC artificial leather per unit thickness. It mainly shows the amount of external tensile force that can be withstood at the pinhole after PVC artificial leather is sutured. Therefore, if the tear strength of PVC artificial leather is too low, it is easy to tear from pinholes or other mouthfuls.</p><p> 3. Cracking strength: refers to the load on the unit area of PVC artificial leather when it is jacked up so that the inside (surface) is cracked. This strength index mainly reflects the processability of <a href="https://www.boseleather.com/pvc-artificial-leather" rel="noopener noreferrer" target="_blank">PVC </a>artificial leather, but it is not very important in actual wearing.</p><p> 4. Anti-bending strength: refers to the number of times the PVC artificial leather is bent when it is repeatedly deformed and its surface is damaged. The level of this indicator has a great impact on the wearing life of some PVC artificial leather products. For example, the soft cattle upper leather has a bending resistance dozens of times higher than that of the modified cattle leather. The former has a higher bending strength than the latter and is not easily broken during its use.</p><p><br></p>
