Automotive carpet

The use of polyurethanes in the pressure-sensitive adhesives market has been relatively small. Polyurethanes have been somewhat limited to being used as additives to pressure-sensitive adhesives to improve their cohesive strength. Recent developments in the institutional carpet backing or automotive carpet floor mat markets suggest that pressure-sensitive urethanes can succeed commercially [89]. 

Carpet Original floor coverings were durable rubber mats. Once the closed cars were developed, other materials were evaluated for use. Initially natural fiber matting was used, but as synthetic materials came onto the market, they replaced the natural materials. This started in the 1950s with tufted rayon [9]. Soon rayon was replaced by nylon, a particularly durable plastic that has remained the material of choice in modem automotive carpet systems.

Polyamides. In 1988, 77% of U.S. demand for adipic acid was for nylon-6,6 fiber, while 11% was used in nyon-6,6 resins (195). In Western Europe only about 66% was for polyamide, because of the stronger competition from nylon-6. The fiber appHcations include carpets (67%), apparel (13%), tire cord (7%), and miscellaneous (13%). Nylon-6,6 resins were distributed between injection mol ding (85%) for such appHcations as automotive and electrical parts and for extmsion resins (15%) for strapping, film, and wire and cable. 

The products from the continuous process (buns) are cut to shape for the particular appflcation, while the molded foams ate formed to shape during the mol ding process. The density of the continuous buns is traditionally between 16-32 kg/m (1-2 Ibs/ft ). Molded foams have densities greater than 32 kg/m. Flexible foams find appHcafions as automotive cushions, carpet underlay, furniture, seating, and bedding. 

Principle appHcations of needle-punched nonwovens for the 1990s include automotive, apparel components, blankets, carpeting, carpet pa dding, coating substrates, filtration, furniture, geotextiles, insulation, roofing substrates, and wall coverings. In 1990, the production of needle-punched fabric was estimated to approach 91,000 t and 606 million square meters (15). 

These cross-linked cellular materials have been used in the automotive industry for carpeting, boot mats and sound deadening. They have also found use for pipe insulation and as flotation media for oil-carrying and dredging hose. 

Prodnction of Nylon-6 from caprolactam is an important global industrial process. Of the several billions of pounds of caprolactam produced armually, most is polymerized to Nylon-6 [1]. Nylon-6 polymer is used in the manufacture of carpets, automotive parts and sporting goods as well as in films and packaging.

Nylons belong to the class of polymers known as engineering polymers that is, they are strong, tough, and heat resistant. We can readily extrude and mold nylons to form a wide variety of useful objects, such as tubing, furniture casters, and automotive air intake ducts. Nylons are commonly spun into filaments or fibers. These can be used directly, or braided, or twisted to form threads, yarns, cords, and ropes, which may be further woven to make fabrics. In their fibrous forms, nylons are used in carpets, backpacks, and hosiery. 

Some of the nonrubber applications are as a chemical intermediate to make adiponitrile and hexamethylenediamine, precursors to making Nylon 66 whose primary application is carpeting. Other nonrubber applications are styrene-butadiene latexes for paper coatings and carpet backing, and acrylonitrile-butadiene-styrene (ABS) resins for plastic pipe and automotive/appliance parts. 

When the polypropylene (PP) technology finally ripened in the late 1950s, the chemicaL.industry was quick to harvest numerous applications. The primary attractions of this thermoplastic were the ease of molding or extruding it and its ability to hold color. Some of the familiar applications are automotive parts, luggage, pipe, bottles, fiber (particularly carpet face fiber and rope), housewares, and toys.
