In recent years, the fiber industry in Western countries has become increasingly sluggish due to factors such as rising chemical raw material prices and high labor costs caused by rising oil prices. The rise of the third world nation-state industry has intensified this downturn. Although the total fiber production tends to decrease, polyolefin fibers (mainly polypropylene) have increased significantly over the years, with polyolefin fibers and carpet filaments rising continuously. Therefore, it can be concluded that the sluggish production of the entire fiber does not affect the production of carpet and polypropylene fibers. The main use of polypropylene fiber is in the two fields of non-woven fabrics and carpet yarns.
Because household carpets are generally premised on high quality, nylon is used as the noodles, while nylon carpets are used in public places, but they are replaced by polypropylene carpets. From the percentage and growth trend of these uses, although nylon carpets currently have an absolute advantage, the use of polypropylene in carpets is on the rise, while nylon has a downward trend. Polypropylene BCF yarn has become the mainstream raw material for carpet weaving.
There are two kinds of carpet surface yarns: BCF and short yarn. The application of polypropylene in carpet silk is mainly in the form of BCF. Amoco, Herculos, and Philips, the three largest polypropylene producers in the United States, produce polypropylene BCF yarns. In 84 years, the annual output of the three companies was 35.32 million tons, 20.43 million tons, and 0.408 million tons. Other small factories also produce polypropylene BCF yarns.
The material of the tufted carpet first backing is 100% polypropylene fabric. There are two types of tufted fabrics, one is a flat woven fabric and the other is a thin woven fabric. The spray adhesive of the United States is the "Tapon" produced by Dupont. The first backing of the nylon tufted carpet using these polypropylene woven or sprayed woven fabrics is generally a thin layer of natural nylon short fibers needled on the tufted side of the backing. After dyeing, the silk and the chen have the same color.
The material of the second backing of the velvet carpet is more complicated. But the most used is polypropylene, or the fabric of polypropylene and jute.
Carpets are ground coverings made of cotton, hemp, wool, silk, grass and other natural fibers or chemical synthetic fiber materials, which are knitted, woven or woven by hand or mechanical process. It is one of the world's fine arts and crafts with a long history. Covered in houses, hotels, stadiums, exhibition halls, vehicles, boats
The ground of ships, airplanes, etc., has the effect of reducing noise, heat insulation and decoration.
