Nonwovens, as the name suggests, are fabrics that are not woven, but also called "nonwoven fabrics".
Process principle: the chemical fiber is combed through the carding machine, and then the base cloth is formed by high temperature hot rolling. Then a layer of hot melt adhesive is coated on the surface of the substrate by a coating machine, and then dried to form the non-woven interlining we use.
Usage: Place the glued side of the interlining on the fabric, then melt the glue on the interlining by heating it with a gluing machine or iron, so as to achieve the effect of gluing on the fabric.
Features: cheap, soft or hard, but not washable.
