Non-woven fabrics can be divided into spunbond, chemically bonded, thermally bonded, meltblown and other types, which have been applied in all aspects of people's lives. The following is a non-woven industry policy and environmental analysis.

Policies and environment of the non-woven industry

The analysis of the non-woven industry pointed out that China is the world's largest non-woven production and consumption country. In 2019, the annual output of various types of nonwovens in China reached 5.9322 million tons, an increase of 196.31% over 2009, with an average annual compound growth rate of 11.47%. China's non-woven production will maintain a high single-digit growth rate in the next five years. Driven by the new crown pneumonia epidemic, the growth of non-woven fabrics will definitely exceed previous estimates. In addition to the medical demand brought about by the epidemic, the areas with relatively fast growth in non-woven fabric demand include sanitary napkins, baby diapers, adult incontinence products and Other cleaning wipes.

As of the first half of 2020, the production capacity of China's meltblown non-woven fabrics is 83,240 tons, and the actual output is 53,523 tons. The actual output of melt-blown non-woven fabrics accounts for only about 1% of the overall non-woven fabric market, and the production capacity is relatively high. limited. The non-woven industry policy and environment pointed out that there are fewer companies that can provide meltblown fabrics, which are more important for medical masks. The companies whose business scope involves meltblown fabrics are mainly concentrated in Jiangsu (23.53%) and Zhejiang (13.73%). and Henan (11.76%), accounting for 49.02% of the country.

From the perspective of consumption structure, the largest application field of Chinese non-woven fabrics is medical and health care, while 60%~70% of non-woven fabrics in the US market are used in medical and health care and daily necessities. In Japan , Non-woven fabrics consumed by industrial, medical and hygiene products accounted for 57.4% of the demand. Due to the high cost of use, the proportion of disposable protective non-woven products in China is far lower than that of developed countries, and the consumption of medical non-woven fabrics still has a lot of room for development.

From the perspective of industrial structure, China's industry is located at a relatively low-end position, and the structure is relatively scattered. China's non-woven industry started relatively late, relying on the introduction of technology and equipment from overseas, and relying on labor advantages to build competitiveness in the non-woven manufacturing end. At present, the domestic non-woven manufacturing pattern is still relatively scattered.

At present, with the rapid development of China's economy and the continuous improvement of residents' income, the demand for the non-woven industry has not been fully released. The non-woven industry policy and environment point out that, for example, the market for sanitary napkins and baby diapers is very broad, and the annual demand is hundreds of thousands of tons. Medical care is gradually developed, and China's population is seriously aging, and the use of non-woven fabrics in medical care is also showing a rapid growth trend. The market for hot-rolled cloth, SMS cloth and air-laid cloth, filter material, insulating cloth, geotextile and medical cloth is large and will become larger and larger in industry and engineering.

In addition, in the two fields of disposable hygienic absorbent materials and wipes, the trend of consumption upgrading is very obvious. With the development of the economy, people have higher and higher requirements for the functionality, comfort and convenience of sanitary care products, and non-woven fabrics with specific properties are more and more widely used in related fields, and the sales of disposable non-woven fabrics The growth rate of the total amount has also continued to be higher than the growth rate of the overall non-woven fabric. In the future, in terms of disposable absorbent materials and wiping supplies, the technical upgrade of non-woven fabrics (performance improvement, unit gram weight reduction, etc.) is still a major trend. The above is all the content of non-woven industry policy and environmental analysis.

Spun-bond process is one of the main methods for the production of non-woven materials, also known as spunlaid or polymer extrusion. The principle of the spunbond method is to use the method of chemical fiber spinning, spinning, drawing, and laying the polymer into a web, and finally reinforced by acupuncture, spunlace, hot rolling or self-bonding to form a non-woven material.

Spunbond is one of the non-woven technologies. Its origin and development is a continuation of the commercial synthetic filament spinning process in the 1940s and 1950s. Its origin can be traced back to two In the 1940s and early 1950s, the U.S. Naval Laboratory established a small melt extruder to extrude the melted polymer from the spinneret to form fine filament fibers. Then, the hot air is blown onto the netting curtain to make the fibers bond to form a net. This is the earliest spinning technology, but due to the limitation of the technology at that time, this technology cannot be studied.

With the development of chemical fiber technology, the German Freudenberg Company and the American Dupont Company began to study the spunbond nonwoven technology in the late 1950s. For reasons such as perfection, the research results of this technology have not been promoted. In the 1960s, the American Du-pont company applied for a patent, and industrial production began in the mid-1960s. In the late 1960s and early 1970s, the spunbond nonwoven technology was developed. The German Reifen Company adopts an integral horizontal Venturi drafter, which greatly improves the quality of spunbonded non-woven fabrics, and the degree of industrial production has also been greatly improved. Later, the American Essen Company applied the meltblown technology to the spunbond technology. Due to the special structure of the drafter, this made the spunbond nonwoven technology have a greater development.

Due to the rapid progress of spunbond production technology, high growth rate, large production capacity, high quality, excellent performance, wide product application range, strong market adaptability, coupled with spunbond non-woven fabrics The production process is short, the production efficiency is high, and it has the advantages of large-scale production, among which the strength and elongation properties of the spunbond non-woven fabric are better. At present, with the emergence of meltblown and spunbond multi-nozzle composite technology, bicomponent and other differential fiber spinning technologies, spunbond non-woven technology has brought a broader application prospect, so the nineteenth century After the ten years, spunbond non-woven fabrics will be developed more rapidly and widely in terms of product use and technological advancement.

According to the ingredients, non-woven fabrics include polyester, polypropylene, nylon, spandex, acrylic, etc.; different ingredients will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of these two kinds of fabrics are very similar, and can only be judged by high temperature test.

Introduction

The manufacturing of medical nonwoven fabric plays a crucial role in the healthcare industry. This versatile material is widely used in the production of various medical supplies, including surgical gowns, masks, and drapes. Its unique characteristics, such as breathability, liquid resistance, and filtration capability, make it an essential component in maintaining a sterile environment and preventing the transmission of infectious diseases. In this article, we will delve into the behind-the-scenes process of manufacturing medical nonwoven fabric, examining each step in detail and exploring the various techniques employed to ensure its quality and effectiveness.

The Raw Materials

The manufacturing process of medical nonwoven fabric begins with the careful selection of raw materials. These materials are typically polymers derived from petroleum, such as polypropylene, polyester, or polyethylene. Polypropylene is the most commonly used polymer due to its excellent properties, including high tensile strength, durability, and resistance to chemicals. The chosen polymer is melted down and extruded into fine filaments, forming the basis for the nonwoven fabric.

Spinning the Filaments

Once the polymer is melted, it is pushed through spinnerets, which are small holes or nozzles arranged in a specific pattern. The shape and size of these spinnerets determine the characteristics of the resulting fabric. The molten polymer is forced through the spinnerets, creating continuous filaments. These filaments are then cooled and solidified through a process called quenching, in which they are exposed to cool air or water jets. The quenched filaments are collected onto a moving conveyor belt or drum, forming a loose web of fibers.

Laying and Bonding the Fibers

To transform the loose web of filaments into a cohesive fabric, the fibers need to be laid and bonded. There are several methods employed to achieve this, including thermal bonding, chemical bonding, and mechanical bonding.

Thermal Bonding

In thermal bonding, the loose fibers are subjected to heat and pressure, causing them to fuse and bond together. This process typically involves passing the web of fibers through a pair of heated rollers or plates. The heat softens the polymer filaments, and as the fibers come into contact, they adhere to one another. The temperature and pressure applied during thermal bonding can be adjusted to achieve different levels of fabric strength and thickness.

Chemical Bonding

Chemical bonding involves the use of adhesive agents to bond the fibers together. These adhesive agents, commonly referred to as binders or resins, are applied to the web of fibers either through spraying or dipping. Once applied, the adhesive undergoes a curing process, during which it solidifies and forms a bond between the fibers. Chemical bonding allows for greater flexibility in terms of fabric strength and texture, as different types of binders can be used depending on the desired properties of the fabric.

Mechanical Bonding

Mechanical bonding is achieved through the use of mechanical processes, such as needle punching or hydroentangling. In needle punching, the web of fibers is passed through a series of barbed needles, which repeatedly penetrate the fabric, intertwining the fibers and creating a bond. This process can be further enhanced by applying heat to the fabric, allowing the fibers to melt slightly and fuse together. Hydroentangling, on the other hand, involves subjecting the fabric to high-velocity water jets, which entangle the fibers and create a mechanical bond. Mechanical bonding is commonly used to produce nonwoven fabrics with higher strength and abrasion resistance.

Fabric Finishing

Once the fibers are laid and bonded, the fabric undergoes a series of finishing processes to enhance its properties. These processes can include coating, lamination, or printing.

Coating

Coating involves applying a layer of coating material onto the fabric's surface. This layer can be a polymer resin, a natural material, or a chemical compound, depending on the desired effect. Coating can enhance the fabric's characteristics, such as water repellency or flame resistance, and provide an additional layer of protection.

Lamination

Lamination is the process of bonding multiple layers of fabric together. This can be achieved through the application of heat and pressure or the use of adhesives. Lamination allows for the creation of composite fabrics with enhanced strength, barrier properties, or specific functionalities.

Printing

Printing involves applying patterns, designs, or graphics onto the fabric's surface. This can be done through various printing techniques, such as screen printing or digital printing. Printed designs can serve both aesthetic and functional purposes, allowing for branding, identification, or informative markings on the fabric.

Quality Control and Testing

Throughout the entire manufacturing process, quality control and testing are paramount to ensure the final fabric meets strict regulatory standards and customer requirements. Various tests are conducted on the fabrics, including measurement of weight, thickness, tensile strength, and barrier properties. These tests help to validate the fabric's performance and durability, ensuring its suitability for the intended medical applications.

Summary

The manufacturing of medical nonwoven fabric involves a meticulous process that starts with the selection of appropriate raw materials and ends with rigorous quality control. The spinning of filaments, laying and bonding of fibers, fabric finishing, and testing stages all contribute to the creation of a high-quality, reliable fabric. By understanding the behind-the-scenes manufacturing process, we gain a greater appreciation for the vital role that medical nonwoven fabric plays in safeguarding the healthcare industry. Its ability to provide a breathable, liquid-resistant, and protective barrier against infectious agents ensures the safety and well-being of healthcare professionals and patients alike.
