إذا أراد جلد الألياف الفائق استبدال جزء من الجلد للأحذية, يحتاج إلى نفاذية رطوبة ممتازة ووظيفة مقاومة للماء, وإلا فإن الأحذية المصنوعة من جلد الألياف الفائقة ستشعر بعدم الراحة.
So how can the shoe material super fiber leather have the functions of moisture permeability and waterproof at the same time? The answer is to make an article on the microfiber leather base cloth.
لأن نفاذية الرطوبة هي في الواقع عمليتان للامتزاز والنقل, it is required to have water vapor (sweat gas) adsorption points on the super fiber leather base cloth, so that the water vapor in the shoes can be adsorbed on the super fiber leather base cloth and then gradually transferred outside the shoes. So how does the adsorption point adsorb water vapor? There are two ways, وهي امتزاز رابطة الهيدروجين والامتزاز المسامي. Because water vapor can easily form hydrogen bond with the nylon fiber of the super fiber leather base cloth, it has certain hydrophilic water absorption performance, so the super fiber leather base cloth has certain hydrophilic water absorption performance. علاوة على ذلك, the microfiber base cloth generally has more pores, so the larger the surface area is, it will help to absorb more water vapor. بعد الامتزاز, the water vapor will be transferred to the outer layer, so the pore size and opening rate of super fiber leather base cloth determine the speed and total amount of transfer.
بالطبع, because the pore diameter of the base cloth is large and uneven, the shoe material super fiber leather has the function of moisture permeability, but the rain is also easy to pass through, انتبه إلى التمسك بشخصيتها وشعورها, it can not achieve the waterproof function. وبالتالي, the super fiber leather base cloth needs special treatment to make it also have certain hydrophobic properties. How did this happen? Because the diameter of water vapor molecules is 4 × 10-4 μ m. In general, the minimum diameter of rain and fog passing through micropores is 20 μ m. The light rain is 400 ~ 900 μ m. Moderate and heavy rain is 2000 μ M above. استخدم جلد الغنم لأول مرة في صناعة الملابس, the pore size of super fiber leather base cloth is designed between the diameter of water vapor molecules and the diameter of rain and fog perforation, which can achieve the function of moisture permeability and water resistance.
To sum up, in the production process of shoe super fiber leather base cloth, reasonable design on the base cloth aperture and opening rate can make the shoe super fiber leather have the functions of moisture permeability and waterproof at the same time.
