A nonwoven fabric is typically made directly from fibers or filaments without the elaborate yarn preparation (weaving beam) 3 required for warp knitting or weaving. In a first step, fibers are oriented in one direction or are deposited in a random manner. This web or sheet is then bonded together by chemical, thermal or mechanical treatment.

The separator coated with Teijinconex meta-aramid maintains its shape even at 250℃. In spot heating tests, Teijin has verified that the separator does not break down even at 400℃. This superior heat-resistance persistently inhibits thermal runaway, enabling LIB production with greater safety. Another type is fluoride coated separator.

16/04/2020Fiber fineness – usually in the range of between 3-5.5 microns – along with strength and absorbency make cotton fibers an ideal material for single-use dry and wet wipes, but there are two reasons for the fiber's limited popularity in single-use nonwovens. Firstly, cotton is usually more expensive than viscose/polyester blends.

About Nonwovens What is a Nonwoven Fabric? Nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally, or chemically. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film.
