The use of functional polypropylene staple fiberis very wide, and with the development of spinning machines, the development and application of functional polypropylene staple fiberis have a broader prospect with the development of nonwoven fabrics. In the past ten years, due to the development of chemical fiber technology and equipment, the international polypropylene fiber production is in the rapid development period, and the yield of polypropylene fibers in my country is also considerable. Its products mainly have ordinary filaments, short fibers, expandable filaments, smoke tow, industria......[ Read More ]
The problems and solutions of the scale production polypropylene short fiber are:1. There will be more defects in the early days, which can gradually solve the adjustment of the cycloptic cooling process parameters.2. The accessories cannot be added one-time, and the mixture needs to be solved forehead before spinning.3. From the initial production of polypropylene short fiber test indicators, the elongation of the modified fibers is large and the strength is low, which is due to the addition of the modified component, and is also related to the spinning process is not reasonable. The elo......[ Read More ]
Affected by the continuous callback of the cost of crude oil prices, the recent polyester plates still show a weaker situation, of which PTA leads to the polyester plate. On the 8th, the PTA trend showed an accelerated situation, and it was a new low in mid-June. The main contract has fallen to 4,744 yuan / ton, and a single decline is nearly 3.5%. In just a month less than a month, the PTA has a falling range has exceeded 12%.Giant repair is late, the PTA is working in line soaringFor the significant weakness of the recent price of PTA, the industry believes that the cost decline, the supply ......[ Read More ]
Polypropylene short fiber with polyamide fibers, polyester fiber light, viscose fiber light, etc. have their own advantages, polypropylene short fibers are mainly raw materials with polypropylene resins, passed through melt spinning, drafting, curl, drying stereotype , Packages and other process processes are colored and colorless, and they specify the fluffy fibers of the number and length.So is a polypropylene short fiber having excellent performance? Light, the density is 0.9 ~ 0.92 g / cubic centimeter, which is the lightest in all synthetic fibers, which is 2% percent than the polyamide f......[ Read More ]
PP short fibers are synthetic fibers made from propylene polypropylene as raw material spinning with propylene polymerization. The trade names in our country is polypropylene.PP short fibers have the advantages of high strength, good toughness, chemical resistance and antimicrobial and low price, so widely used in ropes, fishing nets, seat belts, luggage belts, safety nets, sewing threads, cable foreskin, geotextiles Industrial sectors such as filter cloth, anti-paper felt and paper.The polypropylene woven geotextile manufactured by high fiber strength, acid, alkali, anti-microorganism, and dr......[ Read More ]
Apropylene short fibers There are many kinds of antistatic agents, simply divide into several types, which have advantages and disadvantages. First, the anionic antistatic effect is poor, and its water solubility is good, it is easy to be shuffled, so the durability is poor; the cationic antistatic effect is good, good smoothness and adsorption. But toxic, strong corrosive, mostly used for surface finishing, although both gender have both antistatic properties, but faded at high temperatures, the proliferation of polypropylene short fibers is more expensive. Apropylen......[ Read More ]
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 ]
