PET reclaimed masterbatch granulator

The short fiber of man-made fiber is called "fiber" (be like, rich fiber), the short fiber of synthetic fiber is called "fiber" (be like polyamide, dacron).For long fibers, add "silk" or "filament" (such as viscose, acrylic, etc.) at the end of the name.

China has become the world's largest producer of chemical fiber as global production shifts further to China.China produces more than 60% of the world's chemical fibre., the rapid development of chemical fiber industry in China has improved significantly, complete the objectives of the planning task, vigorously promote and support the development of the textile industry and related industries, to further improve the position and role of the chemical fiber industry in the world.

In 2012, China's chemical fiber output totaled 387.62 million tons, an increase of 5 million to 12 million tons over the same period last year, an increase of 14.82 percent.Chemical fiber and its products have formed a complete industrial supporting basis, the international market competitive advantage is obvious.

In 2013, China's chemical fiber industry realized a total profit of 25.98 billion yuan, up 18.3% year on year.Behavior was 3.6%, up 0.3 percentage points from 2012.In 2013, chemical fiber production continued to grow, with a total output of 41.22 million tons in the whole year, up 7.9 percent year on year.Among them, dacron 33.41 million tons, up 6.6 percent year on year, down 2.8 percent growth rate;Spandex production grew the fastest, up 27.3%.In 2014, the total profit of chemical fiber industry was 27.73 billion yuan, up 6.7% year on year.The total profit continued to increase from 2012 to 2014.2014 chemical fiber industry 10.06%.From 2010 to 2014, the gross profit rate of China's chemical fiber industry increased steadily with less fluctuation.

According to the release of China's chemical fiber industry of China industry research network research present situation and future development trend analysis report (2016-2020), according to "much starker choices-and graver consequences-in" period, as the world economic recovery and development, in the continued growth of the international textile clothing market demand trend leads, the chemical fiber industry as raw materials of textile clothing industry will continue to maintain growth, China's chemical fiber and its products with the evident in the international competition advantage, and continue to expand the international market space.

At the same time, with the further improvement of domestic people's living standards and the acceleration of the progress, it will also directly promote the increase of chemical fiber product consumption.Therefore, the future of China's chemical fiber industry is still promising

Chemical fiber preparation, is usually the first natural or synthetic polymer material spinning melt or solution, and then filtered, metering, extrusion to trickle, liquid by plate) and then frozen fibers.At this time, the fiber is called primary fiber, its mechanical properties are very poor, it must go through a series of post-processing procedures to meet the textile processing and use requirements.The post-processing is mainly aimed at fiber pulling to improve the mechanical properties of fiber.Stretching is the orientation of large molecular or structural elements along the fiber axis in primary fibers.The thermosetting is mainly to relax the fiber.The post-processing of wet spinning fiber also includes washing, oiling and drying.When spinning the filament, it can be wound into a tube through the above procedure.The winding, cutting and packing of short fiber should be added.Among the raw materials used in the production of textiles, cotton, hemp, silk and wool have the longest history.However, the natural resources are limited after all. The yield of cotton is about 50kg/ha.So chemists began to study the use of cheaper, more abundant materials for spinning fabrics called chemical fibers.
