Due to the rapid economic development, the research on this new type of functional yarn is becoming more and more perfect. Polypropylene is also developing rapidly due to its simple process, low cost, and relatively high strength. It is now one of the four major chemical fibers and one of the common synthetic fibers.Polypropylene staple fiber is a single kind of filament formed by polypropylene as a raw material after polymerization and melt spinning. It is the lighter single species of common fibers, and the sales volume has been increasing in recent years. This requires manufacturers to comp......[ Read More ]
Since the first delivery of the 2105 staple fiber contract, the staple fiber futures has completed the smooth delivery of 3 contracts. After being listed for less than a year, the delivery volume of staple fiber futures has surpassed many futures that have been listed in the same period or even run for many years, and market recognition has continued to increase. The further optimization of the delivery system has effectively guaranteed the return of future prices, and the prices have become more realistic and reasonable. With the continuous improvement of the delivery system and the expansion......[ Read More ]
Polypropylene staple fiber is made from polypropylene as a raw material through processes such as melting, drawing, spinning, and cutting. In the process of making polypropylene staple fiber, functional masterbatch, such as anti-aging masterbatch, flame retardant masterbatch, etc. can be added as needed to increase the performance of polypropylene staple fiber. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used to make felt and used for filter material.The characteristics of polypropylene staple fiber: polypropylene staple fiber has low density, light weight, an......[ Read More ]
The sea shipping industry in the world is in its biggest dilemma in 65 years! Port congestion and rising or continuing freight rates have become the main theme in the first half of next year! Since the outbreak of the new crown epidemic, the disadvantages of backward port infrastructure on a global scale have become increasingly prominent. According to Kuehne+Nagel's real-time data, there are currently 353 cargo ships blocked in ports around the world, twice the number at the beginning of the year. There are 22 freighters waiting outside the Port of Long Beach and Los Angeles in the Unit......[ Read More ]
Fibers are divided into chemical fibers and synthetic fibers, so how is it distinguished?Chemical fibers are used by artificial fibers other than natural fibers. Chemical fibers can be divided into regenerated fibers and synthetic fibers. The regenerative fiber is a chemical fiber made of natural product (cellulose, protein, etc.) and is made of spinning process. Synthetic fibers are chemical fibers made of polymers such as chemical raw materials such as organic monomers, commonly used synthetic fibers include polyester, nylon, acrylic, spandex, polypropylene, vivine, and the like. Among them,......[ Read More ]

Polypropylene staple fiber has its own advantages compared with polyamide fiber, polyester fiber, light viscose fiber, etc. Polypropylene staple fiber uses polypropylene resin as the main raw material, which is melt-spinning, drafting, crimping, and drying to shape and cut. Colored and colorless, fluffy fibers with specified denier and length. So what are the high-quality properties of polypropylene staple fiber? Lightweight, its density is 0.9～0.92 g/cm3, which is the lightest among all synthetic fibers. It is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, and 40% l......[ Read More ]
The polypropylene staple fiber looks like a ball of cotton, soft and elastic. The polypropylene staple fiber has a large elongation performance, and it is easy to control poorly in production. The elongation will be over 60% longer, except for its polypropylene macromolecules. In addition to its own structural factors, the polypropylene staple fiber may not be stretched enough during the production process, because of the large unevenness of the yarn, the increase in the stretching ratio may cause the roll to break, or sometimes it will retract after pulling the foot. In production, it is ofte......[ Read More ]
