Distinct characteristics of non-woven fabrics are also different. Non-woven products are fast in production, low in cost, and can be used once to avoid the infection caused by the long-term use of the fabric in the medical environment. Non-woven materials have many advantages suitable for medical environments making non-woven fabrics more and more widely used in medical scenarios.
Non-woven fabric is a new generation of environmental protection materials, with moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic, no stimulation, rich color, low price, and other characteristics, can be recycled, and other advantages. Of course, different non-woven fabrics can achieve different product properties.

In the medical field, the primary raw material of the non-woven fabric is polypropylene fabric. You can use it to make disposable surgical gowns, isolation gowns, masks, and surgery drapes. With different production methods, the characteristics of non-woven fabrics are not the same. Here, we take the spun-bond non-woven fabric, melt-blown non-woven fabric, and spun-lace non-woven fabric as examples to discuss their advantages.
With polypropylene resin as the raw material, the density is only 0.91, less than nylon and other materials.
Compared with products of the same weight, the thickness is thicker, and the fluffiness is good.
The finished product is soft and heavy, with a comfortable feeling.
With good air permeability, polypropylene resin does not absorb water, is composed of 100% fiber, has porous, and is easy to keep the cloth dry.
Polypropylene spun-bond non-woven fabric does not contain other chemical components, is non-toxic, has no peculiar smell, and does not irritate the skin.
Polypropylene resin is a chemical composition of blunt material, and chemical corrosion resistance is good. The product is not easy to receive erosion and affects strength.
Good antibacterial properties, no mold, can isolate bacteria and parasite erosion in the liquid.
Polypropylene resin is a plastic resin that can be applied to various processing methods, such as needle processing or hot melt suture processing.
The chemical structure of polypropylene is unstable, and the molecular chain breaks easily, which can be effectively degraded and entered into the next environmental cycle in the form of pentacenes.
The fiber diameter of polypropylene melt-blown non-woven fabric can reach 1-5 microns, with more gaps, fluffiness, and good wrinkling resistance. The microfiber with a unique capillary structure can increase the number of fibers per unit area and surface area so that the melt-blown non-woven fabric has good filtering, shielding, insulation, and oil absorption.
Polypropylene melt-blown non-woven fabrics often appear as the filter layer of medical masks, which bears the important task of filtering air and blocking bacteria.
Polypropylene is the most commonly used raw material in spun lace non-woven fabrics. The density of polypropylene is small, and the fabric made of polypropylene fiber can get a larger area under the same weight. You can use less material and get the same amount of fabric area, thus saving on the cost of raw materials.
Polypropylene spun-lace non-woven fabrics have high strength, are comfortable and soft to the touch, have good moisture absorption, and are not easily eroded by chemical agents. In all non-woven products, the performance is closest to that of textiles. It's the raw material of surgical clothes, medical bandaging materials, disinfection wipes, masks, etc.
There are many raw materials for the production of non-woven fabrics, and the characteristics of the products are not the same.
Some non-wovens are soft and elastic, and some are hard and hardly elastic; They can be paper-thin or very thick; They can be translucent or opaque; Their porosity can range from low tear strength and blast resistance to very high tensile strength.
Non-woven products are fast to produce and low in cost, and they have many advantages suitable for use in medical Settings. Many non-woven products can be used once, such as surgical gowns, surgical masks, surgical tablecloths, surgical aprons, etc., to avoid infection caused by the long-term use of fabrics in the medical environment. So more and more non-woven products are used in the medical field.
