Transfer PU breathable fabric: How do microporous technology and hydrophilic groups work together to improve breathability?

The core of transfer PU breathable fabric lies in its unique microporous structure. This structure is not simply to punch holes in the fabric, but to evenly attach a very thin PU film to the fabric base through advanced transfer coating technology. This film not only maintains the original strength of the fabric, but also forms many tiny and uniform breathable holes on its surface and inside. These holes are like miniature ventilation ducts, which can allow air and water vapor molecules to pass freely in a diffusion manner while ensuring the strength of the fabric, thereby achieving efficient breathability.

The key to microporous technology lies in the size and distribution of the holes. Too large holes may sacrifice the windproof and warm performance of the fabric, while too small holes may affect the breathability efficiency. Transfer PU breathable fabric ensures that the fabric can maintain high strength and windproof performance while still having excellent breathability by precisely controlling the size and distribution of the holes. This design allows the fabric to quickly discharge sweat vapor generated by the human body, avoiding the stuffiness and discomfort caused by excessive humidity.

In addition to microporous technology, the hydrophilic groups in the transfer PU breathable fabric are also one of the key factors in improving its breathability. Hydrophilic groups refer to functional groups that can form hydrogen bonds with water molecules. They are usually introduced into the molecular chain of the PU membrane to improve the moisture permeability of the fabric.

When the human body sweats, the sweat is first absorbed by the fibers in the inner layer of the fabric. In the transfer PU breathable fabric, the sweat will quickly contact the hydrophilic groups on the PU membrane. By forming hydrogen bonds with water molecules, the hydrophilic groups can quickly adsorb sweat molecules to the membrane surface and conduct them along the microchannels in the membrane. This conduction process not only accelerates the evaporation rate of sweat, but also makes the diffusion of sweat inside the fabric more uniform, avoiding the problem of local over-wetting.

It is worth noting that the introduction of hydrophilic groups does not affect the breathability of the fabric. On the contrary, they further improve the moisture permeability efficiency of the fabric through the synergistic effect with microporous technology. When sweat is adsorbed by the hydrophilic groups and conducted to the membrane surface, the microporous structure can quickly discharge these water molecules to the outside in the form of steam, thereby achieving a rapid reduction in the humidity inside the fabric.

The synergistic effect of microporous technology and hydrophilic groups has made the transfer PU breathable fabric achieve remarkable results in breathability and comfort. With the support of microporous technology, the fabric can quickly discharge the sweat vapor produced by the human body, avoiding the stuffiness and discomfort caused by excessive humidity. The introduction of hydrophilic groups further accelerates the conduction and evaporation process of sweat, so that the fabric can still have excellent breathability while maintaining high strength and windproof performance.

This synergistic effect not only improves the breathability of the fabric, but also significantly improves the comfort of the wearer. In high-intensity activities such as outdoor sports and fitness exercises, the human body will produce a lot of sweat. Traditional fabrics tend to become damp and sticky under the action of sweat, which seriously affects the sports experience and physical health. The transfer PU breathable fabric can quickly discharge sweat to the outside world, keeping the wearer dry and comfortable. This dry feeling not only helps to improve sports performance, but also effectively reduces skin problems and health problems caused by long-term humidity.

With its excellent breathability and comfort, the transfer PU breathable fabric has shown broad application prospects in the clothing industry. In outdoor sports equipment, it can effectively regulate body temperature and keep you dry and comfortable, making it an ideal choice for high-intensity activities such as hiking, mountaineering, and cycling. In fashion and casual clothing, it can bring a light and breathable wearing experience, satisfying the dual pursuit of comfort and fashion by urban people. In addition, in the fields of medical and military, transfer PU breathable fabrics also have a wide range of application potentials.
