The moisture permeability of the fabric refers to the performance of moisture through the fabric, and is also known as water-free, and is thermal balance of thermal balance of thermal balance between human body heat and heat dissipation. Simple understanding is that the rain in the outside is inseparable, the hips from the human body are discharged out by the pores of the coating and the membrane.

The gas permeability of the fabric >
The gas permeability of the fabric refers to the performance of the gas molecules through the fabric, generating air convection, and the direct white, the blow, the air can be directly experienced, mainly affecting the fabric Wearing comfort, such as insulation, warm, transparent, cool, and fabric use performance, etc., in outdoor products, usually combined with windproof functions, that is, wind-resistant and breathable, to ensure the basis of fabric anti-air warming Implement a certain breathable rate to improve wearing comfort. In the outdoor textile product, it is possible to achieve a certain degree of breathableness in the case of blocking 4-5 winds.
Method Air Permeability: It is intended to perform the air through the fabric of the fabric; under the specified differential pressure conditions, the amount of breathable amount is calculated through the gas flow flow through the sample given by the sample for a certain period of time. The airflow rate can be measured directly, or it can be obtained by measuring the differential difference between the flow pore size. This is called real breathable!

Mandipate and gas permeability identification and application >
Functional description is used in the charged clothing class, meaning that more sweat, water vapor can pass through the fabric, keep moving in motion Comfortable.
Wind and breathable function Description Multiple applications in soft-shell products, meant to achieve the wind-resistant and warm-free range by reducing the permeability of the fabric, and confirming the wind resistance range to achieve the windproof and comfort.
