The release paper film fabric is a kind of fabric with excellent air permeability, and its air permeability is mainly determined by the structure of the fabric and the choice of fiber material. The release paper film is a kind of fabric that arranges the fibers into a network structure by physical or chemical methods, and this network structure has a large porosity and a small aperture, so that air can circulate freely and achieve good breathability.
First of all, the release paper film fabric has a large porosity, that is, the porosity in the fabric accounts for a higher proportion of the total volume. This high porosity makes the release paper film fabric can hold more air, thus forming an air layer and improving the breathability of the fabric. By increasing the porosity of the fabric, the release paper film fabric can more effectively remove sweat and water vapor from the body surface, and achieve a fast dry effect.
Secondly, the aperture of the release paper film fabric is small, which is determined by its mesh structure. The small aperture can effectively prevent the entry of moisture and particulate matter and avoid the stimulation of external substances on the skin. At the same time, the small aperture also ensures that the air can flow freely, forming a good breathable channel. By controlling the arrangement and size of the fibers, the release paper film fabric can achieve a smaller aperture and improve air permeability.
In addition, the fiber material selection of the release paper film fabric also has an important impact on the air permeability. Common fiber materials are polyester fiber, nylon fiber and pure cotton fiber. Among them, polyester fiber has good air permeability, and the fiber itself is soft and hydrophilic, which can effectively eliminate sweat and water vapor on the body surface. Nylon fiber has good hygroscopic and breathable properties, and can quickly remove sweat and water vapor from the body surface. Pure cotton fiber has excellent breathability, good skin affinity, suitable for sensitive skin.
Finally, the release paper film fabric can also improve the air permeability by adding air permeability enhancers. A breathability enhancer is a compound added to the fiber to expand the porosity of the fiber material, thereby improving the breathability. The commonly used air permeability enhancers are silicon compounds, nanoscale oxides and microporous polymers. These breathability enhancers can make the release paper fabric have better breathability and improve the comfort of the skin.
In summary, the release paper film fabric has excellent breathability. Its breathability mainly depends on the structure of the fabric and the choice of fiber materials. The release paper film fabric forms larger porosity and smaller pore size through its own network structure to achieve good air permeability. At the same time, the selection of fiber materials and the addition of air permeability enhancers can further improve the air permeability of the release paper film fabric. The excellent breathability of release paper fabric makes it widely used in facial care, medical dressing and functional clothing.
