Adhesives tufted carpet applications

Stabilization of Carboxylated Styrene Butadiene (X-SBR) Latices Carboxylated SBR latices are used as adhesives in applications where durability and flexibility are desired. Some of the major uses for X-SBR latex are in tufted carpet backing, paper coatings, wall and vinyl floor tile adhesives, and pressure-sensitive adhesives. Typically, discoloration is the first measure of the degradation of an X-SBR latex. Discoloration of a dried latex film can often be related to a loss of the physical properties and subsequently, to inferior performance in an adhesive formulation. Figure 9 illustrates the effects of adding an effective antioxidant system to an X-SBR latex on the level of discoloration as a result of static oven aging at 150°C (300°F). The addition of AO-4 alone... 

Adhesives are employed in many textile applications. In tufted carpeting, they have become an integral part of the operation. They provide added strength and stability to nonwovens and fiberfill. Flocking adhesives enable fabrics to look like suede (Table 26). 

Tufted Carpet Backing. The major application of SBR latex is as an adhesive in the tufted carpet industiy. Caiboxylated SBR latex compounded with calcium carbonate filler is used as the adhesive to secure the tufts in the backing and as an adhesive for so-called secondary backings. 

Carpet backing is - after paints, paper and adhesives applications - the fourth largest bulk application of emulsion polymers. About 700 000 tons per year (dry) are used worldwide, mainly as binder for the backing of tufted carpets. The function of a carpet backing is to anchor the pile fibres in place and to improve dimensional stability of the tufted material.
