Definition of non-woven fabric
Non-woven fabrics, the standard name is non-woven fabrics, which are defined as: sheets, webs or webs made of oriented or randomly arranged fibers through friction, cohesion or bonding or a combination of these methods. Padding. Excludes paper, woven fabrics, knitted fabrics, tufted fabrics, stitched fabrics with stitched yarns, and wet felt products. The fibers used can be natural fibers or chemical fibers; they can be short fibers, filaments or fibrous objects formed on the spot.
At present, the commonly used chemical fibers for the production of non-woven fabrics are mainly polypropylene (PP), polyester (PET), in addition to nylon (PA), viscose, acrylic, polyethylene (HDPE), and chlorinated fiber (PVC) and so on.
The commonly used web-forming processes mainly include dry-laid, air-laid, carded-laid, wet-laid, melt-blown, and spun-laid, etc.
Commonly used web consolidation processes include entanglement, thermal bonding, chemical bonding, needle punching, spunlace, hot rolling bonding, dot/print bonding, thermal baking bonding and so on.
The difference between wet-laid non-woven fabric (wet-laid non-woven fabric) and wet-laid papermaking
a) Different raw materials used: wet-laid papermaking usually only uses plant fibers (chemical or mechanical wood pulp), while wet-laid nonwovens must contain a certain amount of chemical fibers;
b) Different production equipment: Wet-laid paper is usually produced by Fourdrinier, cylinder or sandwich paper machines, while wet-laid nonwovens are usually produced by diagonal-wire non-woven machines;
c) The production process is different: wet-laid paper is mainly formed naturally by the chemical bonds on the surface of wood pulp fibers, while wet-laid non-woven fabrics are usually formed by consolidation processes such as chemical bonding and thermal drying bonding. of.
The difference between non-woven fabric and paper and ordinary cloth
In addition to distinguishing from their respective definitions, non-woven fabrics also have some other unique properties. For example, non-woven fabrics are very fluffy, have a high bulk, and have excellent air permeability. In addition, non-woven fabrics It is relatively soft and has a fabric-like feel that paper does not have, and it also has a stiffness that ordinary cloth does not have. That is to say, the feeling of non-woven fabric is between paper and cloth, which is also convenient for non-woven fabrics. When the wallpaper is posted, consumers can distinguish it from the sense of touch. Of course, the biggest advantage of non-woven fabric is its high specific dry and wet strength, which can be peeled off as a whole during the second decoration, which is not available in paper.
