Coated and laminated textile fabrics

Definitions, applications, and attributes of coated and laminated fabrics

Fabric surface modification is a novel technique by coating and lamination which can improve structural performances. It provides the opportunities to manufacturer the special fabrics like water-proof resistant tarpaulins, coverings, large tents and architectural uses, back coating for upholstery including auto seats, food, medical applications, parachutes, woven curtains, for heat-sensitive fabrics, automotive fabrics, disposable hospital apparel etc. the recent developments also enhanced the lamination and coating technique into state-of-art process of the future in textile field.

The processes of coating and laminating have become much more important and novel techniques for adding performance, durability, appearance retention and aesthetic value to textiles. Custom coating and lamination processes add an additional range of property, usages, functionality, improves the ability to perform as needed, and retains overall inherent properties of textiles, all of which have been consistently proven after receiving proper customer coating and laminating services.

Vinyl coated polyester is a material frequently used for flexible fabric structures. It acts as a bonding or adhesive agent, and an exterior PVC coating. Fabric can be manufactured with different levels of light transmission that range from very transparent to completely opaque.

Definitions

There are two definitions of a ‘coated fabric’ in the Textile Institute’s publication, Textile Terms and Definitions.

1A material composed of two or more layers, at least one of which is a textile fabric and at least one of which is a substantially continuous polymeric layer. The layers are bonded closely together by means of an added adhesive or by the adhesive properties of one or more of the component layers.
2A textile fabric on which there has been formed in sit-upon one or both surfaces, a layer or layers of adherent coating material.

The second definition will be regarded as that definition which most closely describes coated fabrics. The first quoted definition could also be applied to a laminated fabric. Textile Terms and Definitions defines a ‘laminated fabric’ (or a ‘combined fabric’) as A material composed of two or more layers, at least one of which is a textile fabric, bonded closely together by means of an added adhesive, or by the adhesive properties of one or more of the component layers.

In simpler terms, a laminated fabric consists two (or more) layer construction with a polymer film bonded to a fabric.

Uses of laminated fabrics are in rainwear, automotive, and other applications are for three-dimensional woven fabrics. For the purposes of this topic, a ‘laminated fabric’, also sometimes called a ‘bonded fabric’, is considered to be different from a coated fabric. However, these definitions are of academic interest and there is little benefit in taking a rigid view.
