Common Polyester Staple Fiber It is very useful

Polyester and polyester fiber difference? Many people for the difference between polyester and polyester fiber is not very understanding, today's polyester fiber manufacturers Xiaobian give you about the difference between polyester and polyester fiber?

     First of all to determine the polyester fiber and polyester is a raw material, why not the same title, because: polyester fiber is the world's common title, mainly because of the earliest production name and famous, and now become the world's general Title; polyester is the title of China, polyester fiber in China is generally polyester. From this point to understand that they are no difference.

    On the brothers do not understand the polyester and polyester fiber, it is simply called flicker, that the same raw materials are fundamentally the same, on the buyers, understand the brothers know the polyester, although the use of polyester is very wide, but there is a certain Defects, therefore, the title between the two is very simple to form the cost of misleading. For this reason we have to understand the advantages and disadvantages of polyester fiber, plenty of knowledge of this raw material.

    Polyester and polyester fiber is widely used, mostly for textiles, can be mixed with other raw materials made of all kinds of imitation cotton, imitation linen, imitation silk fabric, but also because of polyester fiber with excellent non-iron and easy to wash easy to dry Strengths, blends can change the lack of other raw materials. For example, the shortcomings of silk products easy to deal with wrinkles. Of course, polyester fiber and polyester defects that is simple pilling, poor ventilation, but the modern technology has been chemically modified approach is gradually improving these shortcomings.

   Early, propylene polymerization can only get low degree of polymerization of paper products, non-crystalline compounds, no practical value. In 1954, Ziegler and Natta invented the Ziergler-Natta catalyst and made crystalline polypropylene, with a high stereoregularity, known as isotactic polypropylene or isotactic polypropylene. This research has opened up new directions in the field of polymerization, laying the foundation for the extensive application of polypropylene in large-scale industrial production and in the wide application of plastic products and fiber production.

     In 1957, Montecatini of Italy first realized the industrial production of polypropylene. 1958 - 1960, the company will be used for fiber production of polypropylene, developed under the trade name Meraklon polypropylene fiber, after the United States and Canada have also started production.

     1964 years later, but also the development of the binder with polypropylene film cleavage fiber, and by the film fibrillation made of textile fibers and carpet yarn and other products.

     The 20th century, 70 years, short-range spinning technology and equipment to improve the polypropylene fiber production process. In the same period, the continuous filament began to be used in the carpet industry. At present, 90% of the world's carpet floor and 25% of the carpet veil from the polypropylene fiber.

     Since 1980, the quality of polypropylene resins has been significantly improved with the development of new technologies for polypropylene and polypropylene fibers, particularly metallocene catalysts. Due to its increased stereoregularity (isotactivity up to 99.5%), thus greatly improving the inherent quality of polypropylene fiber. In the mid-1980s, polypropylene fine fibers replaced part of the cotton fiber for textile fabrics and nonwovens. With the development of one-step BCF spinning machine, air deformer and compound spinning machine and the emergence and rapid development of nonwovens, the use of polypropylene fiber in decoration and industry has been further widened. In addition, the world of polypropylene fiber research and development is also very active, differentiated fiber production technology popularization and improvement, greatly expanding the application of polypropylene fiber.
