Ten little knowledge about medical nonwovens

In the non-woven fabric industry, we usually hear the names of various fabrics, such as spunlace fabrics, non-woven fabrics, spun-bonded fabrics, etc. The names of these fabrics are different. I believe their materials will also be different. Let’s distinguish them together. What is the difference between nonwoven and spunbond?


Are spunbond and nonwoven fabrics the same material? Spunbond and nonwoven fabrics have a subordinate relationship. There are many production processes for the production of non-woven fabrics, during which the spun bond method is a non-woven fabric production process in which the spun bond method non-woven fabric (including spun bond method, melt blow method, hot rolling method, water stagnation method, now Most of the non-woven fabrics produced on the market are produced by the spunbond method).


According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different compositions will have completely different non-woven personality. Spunbond fabrics usually refer to polyester spunbond and polypropylene spunbond; the personalities of these two fabrics are very close, and they can only be distinguished after high temperature testing.


Non-woven fabric is a kind of fabric that does not require spinning and weaving. It is only oriented or randomly braided short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. . It is not interlaced and braided by individual yarns, but the fibers are directly bonded together by physical means, so when you get the sticky name in your clothes, you will find that It's impossible to pull out any thread. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output value, low cost, wide use, and high quality materials.
