Textiles lamination

Solvent-home urethanes are still widely used to bond leather and athletic shoes. The OEM automotive market uses some solvent-home urethanes together with chlorosulfonated polyethylene as a primer. Some urethane solvent-home packaging adhesives are used for cap liners and for paper and foil lamination. Some textile laminating applications are still based on solvent-home urethanes. 

Flexible polyetherpolyurethane foams are used in cushions, upholstery, etc. While polyester based foams are used in textile laminates, coat shoulder pads, etc. Polyester foams can withstand drycleaning. 

Textiles. Laminates can be constructed in a manner similar to that for surfaced wood veneers but, in place of the wood, with the textile finish of an incorporated linen or hessian fabric.

Polyurethanes find application in many areas. They can be used as impact modifiers for other plastics. Other applications include rollers or wheels, exterior body parts, drive belts, and hydraulic seals. Polyurethanes can be used in film applications such as textile laminates for clothing and protective coatings for hospital beds. They are also used in tubing and hose in both unreinforced and reinforced forms because of their low-temperature properties and toughness. Their abrasion resistance allows them to be used in applications such as athletic shoe soles and ski boots. Polyurethanes are also used as coatings for wire and cable. ... 

The largest consumer of PU adhesive is the textile industry. Applications include textile lamination, integral carpet manufacture and rebonding of foam. Rebonded foam is made using scrap PU foam bonded with a urethane prepolymer and used primarily as carpet underlay. PU adhesives are used to bond film to film, film to foil... 

It is necessary for the development of suitable methods of product fabrication to have some types of polyurethane elastomer which can be processed as solids using similar methods to those employed for conventional natural and synthetic rubbers, namely two-roll mill or internal mixing and compounding procedures, calendering, extrusion, moulding, fabrication of complex rubber-textile laminates and the like. 

A significant volume of flexible foam is used in speciality applications, some of which continue to use the earliest type flexible polyester polyurethane foam used mainly for textile lamination. Reticulatd foams are used in air filters.

These systems are mostly used for hot melt adhesive powders, for instance for textile laminating, liners and we will study this in two other chapters Hot Melts Application and Textile Bonding in the future volumes of this Handbook. 

A complete chapter will be also devoted to the thermoplastic heat sealing films, later in this Handbook. These thermoplastic films are used for textile laminations and for other laminating in various industries. 

Flexible polyurethane foams are open-cell structures which are usually produced with densities in the range 1.5—3 Ib/ft The major interest in flexible foams is for upholstery applications and thus the load-compression characteristics are of importance. Typical load-deflection curves for polyether and polyester foams are shown in Figure 14.2. The most obvious difference between polyether and polyester foams is the lower resilience of the polyester materials. This feature has led to a preference for polyether foams in cushioning applications. Compared to polyether foams, polyester foams have higher tensile strength, elongation at break and hardness consequently polyester foams are preferred in such applications as textile laminates and coat shoulder pads.
