Waterproof and breathable fabric means that water cannot penetrate into the fabric under corresponding pressure, and the sweat emitted by the human body can be transmitted to the outside world in the form of water vapor through the fabric, thereby preventing sweat It accumulates condensation between the body surface and the fabric to maintain wearing comfort. It is a high-tech, functional fabric with unique characteristics. The Waterproof and Breathable Fabric for Jackets introduced by the editor below is a kind of waterproof and breathable fabric.

Waterproof and breathable fabric for jacketsIn the state of water vapor, water particles are very It is so small that, based on the principle of capillary movement, it can smoothly penetrate into the other side of the capillary tube, thereby causing vapor permeability. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules “pull and compete” with each other), the water molecules cannot smoothly break away from the water droplets and penetrate to the other side, which prevents Water penetration occurs, making the breathable membrane waterproof.

Functional treatment to prevent water penetration. Current waterproofing treatments often use waterproof membranes to prevent water molecules from penetrating deeply. However, the membrane itself is too fragile, so it must rely on the surface cloth. , membrane, and lining cooperate with each other to achieve the waterproof function. The waterproof ability is expressed by the water pressure resistance value, that is, a fixed area of ​​​​a waterproof cloth is used to block the rising water pressure. When the third drop of water seeps out from the surface, it is the water pressure resistance value of the fabric. Generally, it can reach the basic level if it exceeds 1000mm. waterproof ability.

Waterproof and breathable fabric for jackets It can be made waterproof and breathable by laminating the expanded PTFE microporous membrane with ordinary fabrics. Wet laminate fabric. Water vapor molecules can pass freely, which can achieve the effect of perspiration and breathability. At the same time, PTFE itself is not hydrophilic, so this PTFE film composite material has good waterproof, moisture-permeable, windproof and warm functions. It is widely used in the production of firefighting suits, jackets, outdoor tents, ski suits, etc. Interested parties are welcome to enter the store for consultation.
