SMS nonwoven anti-virus level 3 isolation gown: technological protection, safety barrier

In the context of the increasingly complex global public health environment today, the demand for personal protective equipment is growing, especially in the medical, epidemic prevention and specific industrial fields, which puts higher requirements on the protective performance, comfort and durability of protective equipment. SMS nonwoven anti-virus level 3 isolation gown, with its unique three-layer structure design - spunbond layer, meltblown layer and re-spunbond layer, as well as rigorous production process, has become a trusted protective equipment for many professionals.

1. SMS nonwoven fabric: three-layer structure, multiple protection
SMS nonwoven fabric, full name spunbond (Spunbond) - meltblown (Meltblown) - spunbond (Spunbond) three-layer composite nonwoven fabric, is a non-woven fabric made of polypropylene (PP) particles through a special process. Its unique three-layer structure design gives SMS nonwoven anti-virus level 3 isolation gown excellent protective performance.

The spunbond layer, as the base layer of SMS non-woven fabric, is composed of continuous filament fibers. The fibers are entangled with each other through hot air or needle punching process to form a stable cloth surface with certain strength. The main function of this layer is to provide the basic strength and stability of the isolation gown, ensuring that it is not easy to be damaged during wearing, and at the same time it can effectively resist the puncture of external objects and provide strong support for the internal meltblown layer.

The meltblown layer, located between the spunbond layers, is the most critical layer in SMS non-woven fabric. Its production process is complicated. The polypropylene particles need to be heated to a molten state and then stretched into extremely fine fibers through high-speed airflow. The diameter of these fibers is usually at the micron level, and some can even reach the nanometer level. This tiny fiber structure gives the meltblown layer an extremely high specific surface area, which can efficiently capture particles in the air, including virus particles, bacteria, pollen, dust, etc. The filtration efficiency of the meltblown layer is one of the important indicators to measure the performance of SMS non-woven antiviral isolation gowns. It determines the isolation gown's ability to block particles in the air.

The spunbond layer, as the surface layer of SMS non-woven fabric, is also composed of continuous filament fibers, but its fiber diameter and arrangement are different from the bottom spunbond layer to further enhance the overall durability and comfort. The design of this layer aims to balance the protective performance and wearing experience, which not only ensures the durability of the isolation gown and avoids damage during frequent wearing or washing, but also improves the softness and breathability of the gown, and reduces the discomfort caused by long-term wearing.

2. Production process: technology-led, excellence

The production of SMS non-woven anti-virus level 3 isolation gown is a process that combines high technology and exquisite craftsmanship. From the selection of raw materials to the production of finished products, every step has been strictly controlled and quality tested.

The selection of raw materials is the basis for the production of high-quality SMS non-woven fabrics. High-quality polypropylene particles, with good thermal stability, chemical stability and mechanical strength, are ideal materials for the manufacture of SMS non-woven fabrics. Before production, the raw materials must be strictly screened and pretreated to remove impurities and ensure the smooth progress of production.

The three-layer composite process of SMS non-woven fabrics is a key link in the production process. First, the polypropylene particles are processed into continuous filament fibers through the spunbond process to form the bottom spunbond layer; then, the meltblown fibers are evenly spread on the spunbond layer to form the middle meltblown layer; finally, a layer of spunbond fibers is covered on the meltblown layer to form a second spunbond layer. The three layers of fibers are entangled with each other through hot rolling or needle punching at a specific temperature and pressure to form a stable three-layer composite structure.

Cutting and sewing are the last steps in making SMS non-woven anti-virus level 3 isolation gowns. At this stage, the SMS non-woven fabric needs to be precisely cut into the required shape and size according to the design drawings of the isolation gown. During the sewing process, high-strength, wear-resistant sutures and strong sealing sewing techniques are used to ensure that every part of the isolation gown can fit the human body tightly while preventing the penetration of viruses and other harmful substances.

After cutting and sewing, the SMS non-woven anti-virus level 3 isolation gown must undergo strict disinfection and testing procedures. Disinfection usually uses ethylene oxide sterilization or high-temperature steam sterilization to kill potential microorganisms and ensure the sterility of the product. Tests include breathability test, liquid barrier test, virus filtration efficiency test, etc. Each test is designed to verify whether the protective performance of the isolation gown meets the established standards.

3. Application field: wide coverage, guarding health
SMS non-woven anti-virus level 3 isolation gown has been widely used in many fields due to its excellent protective performance, comfort and durability.

In the medical field, SMS non-woven anti-virus level 3 isolation gown is an important protective equipment for medical staff. It can effectively block viral particles, bacteria and other harmful substances in the air, protecting medical staff from the risk of infection. At the same time, its good breathability and comfort enable medical staff to stay comfortable during long-term wearing and improve work efficiency.

In epidemic prevention work, SMS non-woven anti-virus level 3 isolation gown also plays an important role. Whether it is conducting epidemiological surveys, epidemic monitoring, or participating in epidemic emergency response, isolation gowns can provide reliable protection for staff and reduce the risk of infection.

In the industrial field, SMS non-woven anti-virus level 3 isolation gowns are also widely used in various occasions that require protection. For example, in the chemical industry, it can prevent harmful chemicals from damaging the skin; in the food processing industry, it can prevent food contamination and cross-contamination; in laboratory environments, it can protect scientific researchers from experimental materials.

SMS non-woven anti-virus level 3 isolation gowns are the perfect combination of technology and health. Its unique three-layer structure design, combined with exquisite production technology and strict quality control, provides users with an efficient, reliable and comfortable protective barrier. Whether in the medical, epidemic prevention or industrial fields, SMS non-woven anti-virus level 3 isolation gowns protect the health and safety of every user with its excellent performance. With the advancement of science and technology and the improvement of people's health awareness, the application prospects of SMS non-woven anti-virus level 3 isolation gowns will be broader, contributing to the construction of a safer and healthier public environment.
