Nonwoven, also known as non-woven fabric, non-woven fabric.
A sheet, web or batt made by orienting or randomly arranging the fibers by friction, cohesion or bonding or a combination of these methods. It does not include paper as well as woven fabrics, knitted fabrics, tufted fabrics, stitchbonded fabrics with stitching yarns, and wet-reduced felts (whether or not such products are needle-punched).
The fibers may be natural or chemically processed, and may be short fibers, filaments or fibers formed in the field.
Note: 1. The difference between wet and non-woven paper is that the non-woven fabric should meet one of the following conditions:
a. Fibers with a ratio of length to diameter of more than 300 in the fiber composition (excluding chemically cooked plant fibers) account for more than 50% of the mass;
b. Fibers with a length to diameter ratio of more than 300 in fiber composition (excluding chemically cooked plant fibers) account for more than 30% of the mass, and its density is less than 0.4/c m3.
