Excellent application and functional analysis of hot pressing composite technology

In the field of modern protective equipment manufacturing that pursues efficient production and excellent performance, the hot pressing lamination technology of PP (polypropylene) non-woven fabrics and PE (polyethylene) films is undoubtedly an important step in the production process of PP+PE non-woven disposable breathable protective clothing. key technologies.

Hot pressing composite technology: display of the essence of craftsmanship
1. Technical principles
Hot pressing lamination technology, as the name suggests, uses high temperature and pressure as the driving force to make two different materials-PP non-woven fabric and PE film closely fit under specific conditions to form a stable and strong bonding layer. In this process, the high temperature promotes the melting and recrystallization of the material surface, while the pressure ensures the close contact and uniform distribution of the molten material, thereby achieving strong composite.

2. Operational advantages
Compared with other lamination methods, hot-press lamination technology has significant operational advantages. First of all, its operation process is relatively simple, easy to realize automated production, and greatly improves production efficiency. Secondly, this technology can complete the composite without destroying the original characteristics of the material, ensuring the excellent performance of the composite non-woven fabric in terms of waterproofing, breathability, softness, etc. Finally, by accurately controlling key parameters such as temperature, pressure and time, the uniformity and firmness of the composite layer can be ensured, providing stable protective performance for protective clothing.

3. Quality control
In the hot-press composite process, temperature, pressure and time are key factors that affect composite quality. Therefore, advanced temperature control systems and pressure sensors need to be used during the production process to monitor and adjust various parameters in real time. At the same time, strict quality inspection of the composite non-woven fabrics is also required, including appearance inspection, peel strength test, waterproof and breathable performance test, etc., to ensure that each composite non-woven fabric can meet the established quality standards.

Functional use: comprehensive display of excellent performance
1. Waterproof performance
Thanks to the excellent waterproof performance of the PE film, PP+PE non-woven disposable breathable protective clothing can keep the interior dry in various humid or rainy environments. This waterproof feature is particularly important for workers who need to frequently come into contact with liquids, such as medical staff and laboratory personnel. It can effectively prevent the penetration of blood, body fluids and other liquids and reduce the risk of infection.

2. Breathability
Despite its waterproof properties, the composite non-woven fabric achieves good breathability through its microporous structure design. This allows the moisture and heat excreted by the human body to be discharged in time, avoiding the discomfort and stuffy feeling caused by wearing it for a long time. This breathability is important for improving wearer comfort and reducing skin problems.

3. Soft and comfortable
PP non-woven fabric itself is soft and skin-friendly, and this advantage is still retained after compounding with PE film. This allows the protective clothing to fit more closely to the curves of the human body when worn, reducing friction and restraint, and providing a better wearing experience for long-term wearers.

4. Durability
The stable bonding layer formed by hot pressing composite technology gives the protective clothing excellent durability. Even under high-intensity use or frequent cleaning, the composite layer remains intact, ensuring that the protective clothing maintains good protective performance over the long term.

5. Widely used
With the above-mentioned excellent performance, PP+PE non-woven disposable breathable protective clothing has been widely used in medical, laboratory, food processing, chemical industry and other fields. They are not only essential protective equipment for high-risk occupational groups such as medical staff and scientific researchers, but also an important tool to protect public health and safety.

The application of hot pressing composite technology in the production of PP+PE non-woven disposable breathable protective clothing not only simplifies the production process and improves production efficiency, but also gives the protective clothing excellent multiple functions such as waterproofing, breathability, softness, comfort and durability. . With the continuous advancement of technology and the continuous expansion of application scenarios, this kind of high-performance protective clothing will continue to play an important role in various fields and protect people's life safety and health.
