PET (polyethylene terephthalate) has been rapidly replaced by many chemical fibers since it was industrialized by DuPont in 1953 due to its good physical processing properties and cost-effectiveness brought about by the cost reduction of large industrial production. Other varieties have now become the largest group of synthetic fibers.
1. Development status of global Pet Preform
Since 2003, global PET production capacity has expanded at an average annual rate of 9%. In 2005, the production capacity has reached 54.7 million tons, and the output in 2005 was 41 million tons. According to PCi’s forecast, by 2008, global PET production capacity will be It has reached 67 million tons and the output is 50 million tons.
At present, the PET product range has also expanded from the original polyester staple fiber to the current series of polyester staple fiber, polyester filament, polyester bottle, polyester film, non-woven fabric, engineering plastics and composite multifunctional products. There are thousands of kinds of products, and the product series is also developed from the initial 100% short fiber to the balanced development of multiple varieties.
The large-scale industrialization of PET in China started in the early 1980s, and it has grown stronger than in the mid-1990s. At present, the production capacity has exceeded 20 million tons, becoming the world’s largest producer and consumer of PET. China Pet Bottle already have in the world market. Very good response, successfully attracted the attention of customers.
