Talking about the production process and products of microfiber nonwoven fabric

Microfiber nonwovens are new technologies and products that have been developed in recent years. Microfibers are a kind of chemical fiber with very fine fineness of monofilament. There are no standard definitions for fine denier in the world, but fibers with a single filament fineness of less than 0.3 dtex are usually called ultrafine fibers. Microfiber nonwoven fabrics have the following excellent properties:
(1) The texture is light and thin, the hand feels soft and comfortable, and the drape is good;
(2) The diameter of the single fiber is reduced, the specific surface area is increased, the adsorption property is enhanced, and the detergency is improved;
(3) There are many fiber roots per unit area, the fabric density is increased, the warmth is good, and it is waterproof and breathable.
Microfiber products are popular in the international market for their unique performance. The world's major companies are competing to develop and continuously introduce new varieties. 
The ultrafine fibers currently used in the production of nonwoven fabrics mainly include split-type composite fibers, sea-island composite fibers, and direct fibers. The processing methods mainly include:
(1) using a split-type or island-in-the-sea composite fiber to form a mesh, and then forming a microfiber by splitting and dissolving;
(2) flashing spinning directly into the net;
(3) Melt-spraying method into a net.
