High-Performance Adhesives for Fabrics

Warwick Mills is an industry leader in engineering high-strength adhesive bonds for exotic textiles

Adhesive Bonds for Textiles
Adhesive bonds for high-performance textiles can be very challenging.

High-performance textiles often have little-to-no chemical bonding sites available, and yet many commercial products use high-performance bonded-fiber composites.

High-performance textile adhesives must be approached with advanced knowledge of chemistry, physics, engineering, and a broad-based experience with adhesive bonds.

Textile Adhesive Bonding Theories

There are four ways to bond to textiles. In many commercial, textile-containing products, two or more of the adhesion principles may be employed.

Mechanical Bonding

The adhesive is applied as a water or solvent-borne material in a dipping operation. After cure the hardened adhesive is mechanically locked to the fabric.

Hydrogen Bonding

Hydrogen bonding is possible in industrial textiles only with polar fibers. In this case there is a strong electrical attraction between the adhesive and the fiber.

Chemical Bonding

Chemical (or covalent) adhesive bonding occurs when there is a chemical reaction between the fiber and the adhesive.

Thermodynamic Bonding

The adhesive swells the top layer of textile and mechanically locks into the fiber layer.

Adhesive Selection for Textile Bonding

Several parameters must be considered when engineering an adhesive for textile bonding:

The capability of the facility

Warwick Mills has the capability to treat textiles with most kinds of adhesives including water borne, solvent borne, and 100% solids.

The wetability of the fabric

In order for the textile and adhesive to make a durable bond, the adhesive must wet the surface. Wetting is governed by the energy difference between the fiber and the adhesive. We have an extensive library of wetting data that is immediately available to assist in adhesive design and selection.

Solubility parameter of the fabric

Solubility parameter is the physical method that describes how adhesive selection can be made with confidence that the adhesive will swell the fiber surface and form a durable bond between the fiber and the adhesive. Solubility parameter values are well known for textile fibers and for general classes of adhesives.
