How to achieve a win-win situation of sealing and breathability of PP/PE non-woven disposable breathable protective clothing?

Jan 02,2025

PP/PE non-woven fabrics have become the preferred material for making disposable protective clothing due to their light weight, wear resistance, corrosion resistance and other characteristics. However, pure PP/PE non-woven fabrics have limitations in terms of breathability, especially in occasions where they need to be worn for a long time, such as medical surgery, chemical operations, etc., the wearer often feels uncomfortable due to stuffiness and humidity. In order to solve this problem, the protective clothing design team introduced PE breathable film.

PE breathable film is a microporous film with a precisely controlled pore size, which can effectively block the invasion of external particles, liquids and harmful gases, and allow air and water vapor to pass freely under a certain pressure. This unique breathability allows the inside of the protective clothing to maintain a relatively dry environment, reducing the stuffiness and discomfort caused by long-term wear. The application of PE breathable film provides basic breathability guarantee for protective clothing.

However, relying solely on PE breathable film is not enough to achieve the best breathability effect. In order to achieve a win-win situation of sealing and breathability, the protective clothing design team conducted in-depth exploration and innovation on the structure of the vent holes.

These vent holes are not randomly distributed, but are precisely calculated and laid out. The design team first analyzed the various environmental conditions that the protective clothing may encounter during use, including temperature, humidity, air flow velocity, etc., as well as the wearer's physiological needs, such as sweating and skin respiration. Based on these analyses, the design team determined the size, shape and distribution density of the vent holes to ensure that the ventilation efficiency is maximized without affecting the overall sealing.

The size of the vent holes is one of the key factors. Too large vent holes may reduce the sealing of the protective clothing, while too small vent holes may limit the ventilation efficiency. Through a large number of experiments and tests, the design team finally determined the optimal size range of the vent holes. This size can effectively block the invasion of external particles and ensure sufficient ventilation, so that the wearer can feel obvious comfort.

The shape of the vent holes is also carefully designed. Different shapes have different effects on ventilation efficiency. The design team tried a variety of shapes, including round, oval, rectangular, etc., and finally found a special shape that can provide sufficient ventilation area and maintain the stability of the vents to prevent deformation or breakage during use.

The distribution density of the vents is equally important. The design team analyzed the changes in ventilation efficiency under different distribution densities through simulation experiments. They found that when the vent distribution density is moderate, the ventilation efficiency is the highest and will not have a negative impact on the sealing of the protective clothing. Therefore, the design team adopted this optimal vent distribution density on the protective clothing.

After determining the size, shape and distribution density of the vents, the design team did not stop exploring. They knew that relying solely on theoretical calculations is far from enough, and actual tests are needed to verify the actual effect of the vent structure.

The design team conducted a large number of experimental tests. They used professional testing equipment to simulate different environmental conditions, including high temperature and high humidity, low temperature and low humidity, etc., as well as different wearing times, ranging from a few minutes to a few hours. During the test, they recorded the temperature and humidity inside the protective clothing and the subjective feelings of the wearer.

Through testing, the design team found some areas that need improvement. For example, under certain extreme conditions, the vents may be blocked or deformed. To solve this problem, the design team further optimized the vent structure. They used special coating materials to enhance the weather resistance and stability of the vents. At the same time, they also increased the number and distribution range of the vents to improve the ventilation efficiency.

After many optimizations and tests, the design team finally determined the best vent structure. This structure not only has excellent breathability, but also maintains good sealing, providing the wearer with a safe and comfortable protection experience.

In addition to the innovative design of the vent structure, the PP/PE non-woven disposable breathable protective clothing also uses special protective clothing adhesive strips and heat sealing technology. This design not only enhances the sealing of the protective clothing, but also makes the wearer more convenient and efficient during the wearing and removing process.

The protective clothing adhesive strip is a special adhesive material with strong adhesion, good weather resistance and not easy to age. The design team applied the protective clothing adhesive strips to all needle and thread seams and key parts such as cuffs, collars, hems, etc. Through heat sealing technology, the protective clothing strips and non-woven fabric materials are tightly combined to form an indestructible sealing barrier. This design not only effectively prevents the intrusion of external particles, but also improves the durability and stability of the protective clothing.

The innovative design of PP/PE non-woven disposable breathable protective clothing (with tape) has shown significant advantages in practical applications. In high-risk environments such as medical, chemical, and electronic manufacturing, workers need to wear protective clothing for a long time to work. Traditional protective clothing often causes the wearer to feel stuffy and uncomfortable due to poor breathability, and even affects work efficiency and health. Protective clothing with specially designed breathable hole structure and protective clothing strips can effectively alleviate this problem.

Many wearers reported that this protective clothing not only has good sealing performance, but also keeps the internal environment dry and comfortable. Even if worn for a long time in a high temperature and high humidity environment, there will be no obvious stuffiness or humidity. This feedback not only verifies the effectiveness of the breathable hole structure and protective clothing strip design, but also provides valuable experience and inspiration for the design team.
