Flow Chart of Nonwoven Fabric Manufacturing Process

Nonwoven fabrics: 

Nonwovens are a sheet, web, or bat of natural and/or man-made fibers or filaments, excluding paper, that have not been converted into yarns, and that are bonded to each other by any of several means. Its different than conventional textile fabrics and paper. Nonwovens are not based on yarns and (with frequent exceptions) do not contain yarns. They are based on webs of individual fibers. Nonwoven fabrics are one of the oldest and simplest textile fabrics. Its classic example is felt. Flow Chart of Nonwoven Fabric Manufacturing Process is as follows:

Nonwoven is comparatively the latest process of fabric manufacturing. Nonwoven fabrics are one type of textile fabrics or a manufactured sheet made of a fibrous layer, which may be a carded web, a fiber web, or any system of randomly laid or oriented fibers or threads, possibly combined with textile or non-textile materials such as conventional woven fabrics, plastic films, foam layers, metal foils, etc., & forming them with a mechanically bound or chemically bonded textile product.

Nonwoven Fabric Manufacturing Techniques:

Nonwoven manufacturing techniques are basically a continuous process in which the web laying and web bonding are performed by two consecutive machines. In general, the nonwoven formation process consists of two basic steps, web formation followed by bonding. The web formation in nonwoven production is a critical contributor to the end-use product performance. There are three basic methods of web formation: dry-laid; wet-laid; and polymer laid. The latter one classified as spunlaid and melt-blown web formations which are particularly applicable for synthetic polymers. There are three basic types of bonding: chemical, thermal, and mechanical. The natural fiber webs can be successfully bonded by the mechanical process without any additives. Additional binder polymer or synthetic fiber is required for the chemical or thermal bonding.
