The term “nonwovens” became popular more than half a century ago when nonwovens were viewed as a low-cost alternative to traditional textiles. Today, however, nonwoven technology is the most modern method used in the textile industry branch. The following is a direct introduction to non-woven fabrics and the related advantages of non-woven fabrics.
What is non-woven fabric?
Nonwovens consist of fibres, filaments or cut yarns which are formed into webs by various methods including mechanical, chemical or physical methods (BSI, 2011). Typical examples include agricultural fabrics, rags, disposable lab coats, surgical gowns and road reinforcement materials. The types of fibers used to make nonwovens are typically polyethylene, polypropylene, polyester, and viscose, but medical end-use items can be made from cotton.
How are non-woven fabrics processed?
Nonwovens are usually made by gathering fine fibers together in sheets or webs (similar to paper on a paper machine). Then bind them mechanically. Like felt, they can be interlocked with serrated needles, allowing friction between fibers to create a stronger fabric. Use adhesive or heat. The adhesive is melted onto the web by applying it and increasing the temperature. Typically, binders are in the form of powders, pastes or polymer melts.
Application of non-woven fabrics in the medical industry
Nonwoven fabrics are traditionally used in medical applications. However, medical products usually require a high level of hygiene to avoid cross contamination. So why can non-woven fabrics be used for medical purposes? This is due to the relatively low production cost, versatility, and various mechanical properties of nonwovens. In addition, it is easy to handle, sheds less hair, is harmless to the human body, and is non-toxic. They are also currently making significant progress in the growing field of healthcare applications. So let’s take a look at the advantages of non-woven fabrics.
Advantages of non-woven fabrics
The non-woven fabric maintains its durability in both wet and dry conditions. It also resists wear and tear and is difficult to remove. When it’s wet, it barely absorbs any moisture. Here, list the advantages of non-woven fabrics and learn more about them.
Polypropylene resin is the main raw material for production, its specific gravity is only 0.9, only three feet of cotton, fluffy and good hand feeling.
Products made of FDA food-grade raw materials do not contain other chemical ingredients, have stable performance, are non-toxic and odor-free, and will not irritate the skin.
Polypropylene sheets are non-absorbent and contain no water. The finished product has good waterproof performance and is composed of 100% fiber. It is porous and has good permeability. Easy to keep cloth dry and easy to clean.
This product does not go moldy in addition to water, and isolates the erosion of mold and bacteria without going moldy.
