Civil Construction

Polypropylene accounted for about half of the nonwoven products in industrial uses in 2001. Its share in ropes and nets was 55-60%, and 70-80% in civil construction, where polyester claimed 20-24%. In automotive applications, polypropylene shared 26-30%, nylon almost 50%, and polyester about 20%. Polypropylene contributed to over 86% of agricultural nonwoven, 100% of packaging cloth, 85% of sanitary items, and 64-70% of medical applications. The world consumption of industrial nonwoven products was 1.329 MT in 2000. Polypropylene topped all synthetic fibers with a share of over 40% in this market segment. 

Nonwoven products for use in civil construction amounted to 1.4% in 1985 and increased to 2.3% in 1995. In 1995, about 196 KT of nonwoven construction fabrics were consumed in the United States, 140 KT in West Europe, and 15 KT in Japan. Its market share is estimated to increase to 3.5% by 2005. This growth has been attributed to the wide adoption of nonwoven products in engineering projects on rocky grounds.
