Hot-melt adhesives, e.g., ethylene-vinyl acetate copolymers, polypropylene, polyamides, polyesters. Uses paper, fiberboard, plastics, textiles, leather (assembly bonds). 

Fabrics that are woven together from thread or yam are referred to as textiles, whereas shorter fibres bound together in a random, porous fashion are called nonwovens. In either case, crosslinkable latexes are extensively used as binders to improve stability, durability, and chemical resistance (205), and flame retardance (413). Acrylic copolymers are the most common class of binders, although other copolymers, such as styrene-butadiene or ethylene-vinyl acetate (242, 255) copolymers are often used when required by cost (247) or performance. The softness (flexibility) or hardness (strength) of the fabric is controlled through the glass transition temperature of the latex binder. 

Thermoplastics A number of thermoplastics have been used as adhesives. Polyamides and copolymers of ethylene and vinyl acetate (EVA) are used as melt adhesives. Copolymers of methyl methacrylate and other monomers are used as adhesives in the textile industry. PVAc is often used in school glues. 

The chemicals may constitute a substantial portion of the finished textile. In many cases 10% or more of the fabric s final weight may derive from textile chemicals added to improve or enhance one or another of the fabric s properties. Representative raw materials employed for textile finishing applications are fatty alcohol ether sulfates, vinyl acetate-ethylene copolymers, hydrated alumina, alkylolamides, alkoxylates, chlorinated paraffins, alginates, sodium tripolyphosphates, sorbitan fatty acid esters, ethoxylated triglycerides, and silicones. 

Use Polyvinyl acetate, polyvinyl alcohol, polyvinyl butyral, and polyvinyl chloride-acetate resins, used particularly in latex paints, paper coating, adhesives, textile finishing, safety glass interlayers. A vinyl acetate-ethylene copolymer is available for specialty products. 

Aqueous dispersions of poly(vinyl acetate) and vinyl acetate-ethylene copolymers, homo- and copolymers of acrylic monomers, and styrene-butadiene copolymers are the most important types of polymer latexes today. Applications include paints, coatings, adhesives, paper manufacturing, leather manufacturing, textiles and other industries. In addition to emulsion polymerization, other aqueous free-radical polymerizations are applied on a large scale. In suspension polymerization a water-irnrniscible olefinic monomer is also polymerized. However, by contrast to emulsion polymerization a monomer-soluble initiator is employed, and usually no surfactant is added. Polymerization occurs in the monomer droplets, with kinetics similar to bulk polymerization. The particles obtained are much larger (>15 pm) than in emulsion polymerization, and they do not form stable latexes but precipitate during polymerization (Scheme 7.2).

The largest portion of PVAC adhesives in textiles is a binder for nonwovens and fiberfill. Here the rise in consumption was more than eight-fold as a result of the successful penetration of vinyl acetate-ethylene and vinyl acetate-aciylate copolymers.
