It does not require a fabric formed by weaving yarn , just short fibers or filaments of textile orientation or randomly arranged to form a fiber network structure, and mechanical , thermal or chemical methods such as reinforcement is made . It is the direct use of polymer chips , staple fiber or filament fiber network formed through a variety of methods and techniques of consolidation form with soft , breathable and flat structure of the new fiber products. Definition of non-woven fabric non woven abrasive (nonwoven), also known as non-woven , non-woven . Orientation or randomly arranged fibers by friction , cohesion , or adhesion or a combination of these methods with each other into a sheet , web or batt of fiber . Does not include paper and woven fabrics , knitted fabrics , tufted textile fabrics , stitching yarns with a knit stitch and wet felting felts ( regardless of whether such products through acupuncture reinforcement ) . Fibers may be natural or chemical processing , can be short fibers, filaments or the formation of fibrous spot . Note: 1, the wet nonwoven fabric and the difference between the wet paper making non-woven fabric should meet the following conditions : a, the fiber composition in the ratio of length to diameter of the fibers is greater than 300 ( not including the chemical cooking plant fibers ) accounted for 50 % of the mass ; b, the fiber composition of length to diameter ratio greater than 300 fibers ( not including the chemical cooking of plant fiber ) accounted for 30 % of the mass , and the density of less than 0.4 / c m ⒊ 2, without that the viscose fibers are plant fibers by chemical cooking .
non woven abrasive , English is called felt, directly translated into Chinese should be " felt ." Nonwoven just a popular name , but well expressed its production processes. And our common woven fabric and knitted fabric are different, woven fabrics and knitted fabrics to be the first anti- fibers into a line , then line through the warp and weft knitting or circular knitted fabric made into the final . Rather than weaving into textiles , but rather uses a process similar to papermaking fibers pressed into the fabric . So it has a non-woven paper characteristics , that is, no matter how you cut notches at the same will not be like any other cloth fibers to disperse. It is because of this feature, non-woven production with some minor works will be very convenient. There is a feature of non-woven fabrics than normal to thick, and feel a bit like a woolen material . Use it to produce fabric pieces would be more tangible . Early non-woven wool are used as raw material , which is why translation would be " felt " why. In recent years with the development of technology , more and more non-woven raw material complex, non-woven pure wool is relatively rare in the domestic market , then the price would surely be even more expensive . For non- component non-woven wool , may appear on the surface pilling phenomenon , this should be taken into account at the time of purchase .
