Non woven fabric is defined as a sheet, web or flocculent pad made of directional or randomly arranged fibers by friction, holding, adhesion or a combination of these methods. Non woven fabric is a kind of material processing technology originated from textile but beyond textile. Nonwovens combine four flexible material processing technologies of textile, papermaking, leather and plastic, and the finished products present network structure.
The scientific name of nonwovens is nonwovens, which means nonwovens. There are many kinds of manufacturing technology of non-woven fabrics, and their uses are also different.
Polypropylene is a kind of raw material used in the manufacturing process of non-woven fabrics, which is also common in life, such as Le Kou cup, many of which are made of PP and polypropylene.
Polypropylene is widely used as non-woven fabrics in spunbond, melt blown, hot rolling and other processes, especially in medical and health materials. Generally speaking, most of the non-woven shopping bags in supermarkets are made of polypropylene spunbonded, and the filter elements in household water purifiers are made of polypropylene melt blown materials. Some baby diapers are spunbonded or hot-rolled.
In general, the industry will not say that "100% polypropylene fabric is non-woven". Now the technology is relatively developed, and 100% polypropylene fiber can also be used as fabric (cloth, knitwear) or something.
