Now tarpaulins function is more and more comprehensive, we can't emphasize blindly when use waterproof, but the permeability. As waterproof tarpaulins's main function is special, but to a certain extent, the goods also need fresh air environment 'breathing', which requires tarpaulin factory that the combination of water proofing property and air permeability. Theoretically, waterproof and breathable has certain contradictions: a fabric waterproof performance is good, then its permeability is poor; On the other hand, a breathable fabric performance is good, then its waterproof performance is bad, the key to solve the contradiction is to meet customer's requirement. Tarpaulin factory based on years of experience and research, summarizes two methods: ( 1) The fabric waterproof layer made of perforated, aperture size of 100 microns below, only through air from the hole, and not let water through from the hole, so as to achieve the purpose of the waterproof breathable; ( 2) The fabric of the waterproof coating made of perforated, aperture size is 200 - 500 microns, and implantation of a substance in the hole, the implants in waterproof ( The rain) Absorption expansion plug hole, prevent water from the hole through, without water, The weather is fine) Open water shrinkage hole, let the air from the hole through, thus the purpose of the knife knife waterproof breathable. Analysis not only have good waterproof to protect the goods, good medicine has the good permeability, cannot make the goods gone mouldy, everyone in the choice is to pay attention to this.
