Hot air non-woven fabrics and spunbonded non-woven fabrics are also used as materials in the field of diapers and medical and health care. Because of their similar appearance, they are often confused by people. To distinguish between them, let's take a look at their respective production principles.
Hot-air non-woven fabric: belongs to a kind of thermal bonding (hot-rolled, hot-air) non-woven fabric. After the short fiber is carded, the hot-air non-woven fabric is used to penetrate the fiber web by using the hot air on the drying equipment to make it A non-woven fabric produced by bonding when heated.
Spunbond non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the web It becomes a non-woven fabric. Spunbond nonwovens are long fibers but its raw material is plastic chips.
1. The difference in feel: The more direct method is to touch it with your hands. The hot-air non-woven fabric will feel softer and more comfortable to the touch, and the spunbonded non-woven fabric will feel harder to the touch.
2. Gently pull: get the hot-air non-woven fabric and spunbond non-woven fabric, pull it gently, the hot-air non-woven fabric can easily pull out the silk, if the spunbond non-woven fabric is difficult to pull out the whole piece of silk of.
