ਜੇ ਮਾਈਕ੍ਰੋਫਾਈਬਰ ਚਮੜਾ wants to replace part of the leather for shoe material, ਇਸ ਨੂੰ ਸ਼ਾਨਦਾਰ ਨਮੀ ਪਾਰਦਰਸ਼ੀਤਾ ਅਤੇ ਵਾਟਰਪ੍ਰੂਫ ਫੰਕਸ਼ਨ ਦੀ ਜ਼ਰੂਰਤ ਹੈ, ਨਹੀਂ ਤਾਂ ਮਾਈਕ੍ਰੋਫਾਈਬਰ ਚਮੜੇ ਦੇ ਬਣੇ ਜੁੱਤੀਆਂ ਨੂੰ ਪਹਿਨਣਾ ਅਸੁਵਿਧਾਜਨਕ ਹੋਵੇਗਾ.
So how can microfiber leather for shoes have both moisture permeability and waterproof function? The answer is to do something on the microfiber leather base fabric.
ਕਿਉਂਕਿ ਨਮੀ ਦੀ ਪਾਰਦਰਸ਼ੀਤਾ ਅਸਲ ਵਿੱਚ ਸੋਜ਼ਸ਼ ਅਤੇ ਟ੍ਰਾਂਸਫਰ ਦੀਆਂ ਦੋ ਪ੍ਰਕਿਰਿਆਵਾਂ ਹਨ, then we need to have water vapor (ਪਸੀਨਾ) adsorption points on the microfiber leather base cloth, so that the water vapor inside the shoe can be adsorbed on the microfiber leather base cloth, ਅਤੇ ਫਿਰ ਹੌਲੀ-ਹੌਲੀ ਜੁੱਤੀ ਦੇ ਬਾਹਰ ਤਬਦੀਲ ਹੋ ਗਿਆ. So how can the adsorption point adsorb water vapor? It can be done in two ways, both hydrogen bonding adsorption and porous adsorption. Since water vapor can form hydrogen bond with nylon fiber of microfiber leather base cloth more easily, it has certain hydrophilic adsorption performance, so microfiber leather base cloth has certain hydrophilic adsorption performance. Then again, microfiber base cloth generally has more pores, so the larger the surface area is, the more water vapor will be absorbed. ਸਮਾਈ ਦੇ ਬਾਅਦ, the water vapor should be transferred to the outer layer, so the pore size and open pore rate of microfiber leather base cloth determine the speed and total amount of transfer.
ਜ਼ਰੂਰ, because the pore size of microfiber leather is large and uneven, ਹਾਲਾਂਕਿ ਇਸ ਵਿੱਚ ਨਮੀ ਦੀ ਪਾਰਦਰਸ਼ੀਤਾ ਦਾ ਕੰਮ ਹੈ, rainwater can easily pass through it, which means it cannot reach the function of waterproof. ਇਸ ਲਈ, special treatment of microfiber leather base fabric is needed to make it also have some hydrophobic property. ਇਹ ਕਿਵੇਂ ਕੀਤਾ ਜਾਂਦਾ ਹੈ? The diameter of water vapor molecule is 4×10-4μm, and the minimum diameter of the micro-pore through which rain and fog can pass is 20μm for fog, 400-900μm for light rain, and more than 2000μm for medium and heavy rain. ਆਮ ਆਦਮੀ ਦੀਆਂ ਸ਼ਰਤਾਂ ਵਿੱਚ, it means that the pore size of microfiber leather base fabric is designed to be between the diameter of water vapor molecules and the diameter of rain and fog perforation, and it can achieve the function of both moisture permeability and waterproof.
To sum up, in the process of producing microfiber leather base fabric for shoes, reasonable design in the pore size and opening rate of the base fabric can make the microfiber leather for shoes have both moisture permeability and waterproof function.
