The physical properties of polypropylene staple fibers can be derived from relevant experiments.The main component of polypropylene fiber is polyethylene terephthalate, the mass fraction is about 99%, and the rest is ash, mainly TiO2, and its mass fraction is about 1%. The physical properties of polypropylene staple fiber under normal conditions are known. polypropylene staple fiber has superior moisture permeability and fast drying property, good combability and spinning performance, and can produce soft and tough fabrics. The fabric is light in weight, good in warmth, delicate in hand, comfo......[ Read More ]
Due to its poor intake, polypropylene has developed late in China. It was not until the late 1980s that the rise of the nonwovens industry and the development of the petrochemical industry developed rapidly.Early polypropylene was mainly used in the production of carpets, sprayed cotton and decorative fabrics. The product grade is not high, the market is not working. With the development of the nonwovens industry, especially the large demand for thin non-woven fabrics, polypropylene staple fibers have been used in a large amount, thereby promoting the rapid development of polypropylene staple ......[ Read More ]
This week, the raw material end Fuhai Chuang basically implemented maintenance, the polyester short fiber market fundamentals are still acceptable, the short-term price is still relatively low, but the spot processing interval continues to be above 2000 yuan, coupled with the weakening of polyester demand and other factors. The industry feels that the risk in the market is increasing. Therefore, in the short term, the price of polyester staple fiber may temporarily hold a stable and wait-and-see trend, and there may be a certain downside risk in the medium and long term.Cost support begins to ......[ Read More ]
From January to May, the total profits of industrial enterprises above designated size reached 2,379.02 billion yuan, a year-on-year decrease of 2.3%. (According to the comparable caliber, considering the adjustment of the statistic system, the increase of statistical enforcement, the elimination of duplicate data, the divestiture of enterprise reform, the four classics The impact of factors such as unit inventory, the decline was 1.1 percentage points lower than that in January-April.From January to May, the manufacturing industry realized a total profit of 1,951.94 billion yuan, a decrease o......[ Read More ]
In fact, the difference between polyester staple fiber and polyester filament can be seen on the naked eye. Generally, the fabric woven from filament is shiny and smooth, similar to nylon fabric. It is easy to remember this. The distinction. But in fact, there is still a big difference between polyester staple fiberand polyester filament. Below, Qinfeng will answer for you.polyester staple fiber: The so-called polyester staple fiber is a short fiber of a few centimeters to a dozen centimeters, a cotton staple fiber and a wool type. Cotton type is mostly used for spinning, such as wool, weaving......[ Read More ]

polyester staple fiber is a hydrophobic synthetic fiber. The polyester molecular structure lacks reactive groups such as cellulose or protein fiber that can bind to dyes. The polyester molecules are arranged closely, and there are only small voids in the fiber. When the temperature is low, the thermal motion of the molecule changes its position to a small extent. Under the humid condition of the polyester thermal fuse, the polyester fiber does not enlarge the void by violent swelling like the cotton fiber, and the dye molecules are difficult to penetrate into the fiber. internal. Therefore, in......[ Read More ]
1. Shandong Heze, Jining and Linyi areasMost enterprises in Heze, Jining and Linyi areas mainly produce pure cotton yarn. A small number of enterprises produce cotton blended yarn and purified fiber yarn. The products are mainly sold to Guangdong, Zhejiang and Jiangsu. At present, most enterprises are starting to work normally. Some enterprises are undergoing equipment upgrades or factory relocations, and the operating rate is slightly insufficient.The enterprises in Shandong Province started well in 2019, and the orders were sufficient. Most of the production plans of the enterprises could be......[ Read More ]
Polyester is a fiber made by spinning and processing a fiber high polymer made by exchange and reaction between specific chemical elements. It is widely used in the manufacture of fabrics and industrial products. It has very good setting properties and is an important variety in synthetic fibers. At the same time, polyester is also a cheap, durable and non-deformable fabric.The state of polyester staple fibers is divided into rice grains or flakes, and polyester staple fibers are various in variety and color. The main component of the main products used in our daily life is polyester. It is sl......[ Read More ]
Recently, the polyester industry chain can be described as disaster-prone, and after a short surprise, it is subject to various "crit"! On the trading day after May, the international oil price suddenly suffered a “flash crash” and became a bad month for the entire crude oil market since November last year. The plunge in the crude oil market shocked everyone, and it directly weakened the domestic chemical futures products. PTA futures were also badly hit.Crude oil fell more than 16% in the month, creating a one-month drop in half a year!On the trading day after the Zui in May, the ma......[ Read More ]
polyester staple fiber is a short fiber made by melt spinning, drawing, crimping, heat setting and cutting of PE. The polyester staple fiber production process is like this:First, clear flowers, rolling: the polyester staple fiber polyester staple fiber is poured into the turntable, the original regular fibers are disrupted and combined to form a rolled fiber block;Second, the carding, the stripping, the carding of the bulk of the fiber by the carding machine to continue combing, into a small strip;Third, roving, spun yarn: roving, spinning machine to adjust the strip fiber into the required n......[ Read More ]
In the near stage, the textile market is not prosperous in the peak season, and the high inventory makes the textile boss have a headache! Some textile companies have begun to cut prices to a small extent. In general, price reduction promotion is still attractive to fabric manufacturers, but the effect of destocking is not as good as expected, and fabric buyers are not motivated. Coupled with the recent increase in trade friction between China and the United States, the textile market has caused some panic. Many textile owners say that the most important thing in recent days is to reduce inven......[ Read More ]
