Nonwovens are defined as sheets, webs or batt that are formed by the combination of oriented or randomly arranged fibers by friction, cohesion, bonding or a combination of these methods. Non-woven fabrics are a material processing technology that originates from textiles but transcends textiles. The non-woven product combines four flexible material processing technologies of textile, paper, leather and plastic, and the finished product has a network structure.
A non-woven fabric, a non-woven fabric, that is, a fabric that is not interwoven with warp and weft yarns, meaning that there is no woven fabric. There are many different manufacturing processes for non-woven fabrics, and their uses vary widely.
Polypropylene is a raw material used in the manufacture of non-woven fabrics, and is also common in life, such as the button glass, many of which are PP and polypropylene.
Polypropylene is used as a non-woven fabric for spunbonding, melt-blown, hot-rolling, etc., and is mostly used in medical and sanitary materials. Generally speaking, the supermarket's non-woven shopping bags are mostly polypropylene spunbonded, and the filter in the household water purifier is polypropylene meltblown material. The surface of some baby diapers is polypropylene spunbonded or hot rolled.
In the general industry, it is not said that "100% polypropylene fabric is non-woven fabric". Nowadays, the technology is relatively developed, and 100% polypropylene fiber may also be used as fabric (cloth, knitwear).
