After experiencing the ultra-light textile off-season in recent years, the textile industry has not been able to hope for a pure traditional textile season. It is more appropriate to use "super-anxiety" to describe this year's Golden September.Affected by unfavorable factors such as the slowdown in global economic growth and the growing Sino-US trade war, the “great environment” in the textile population is slowly consuming the market confidence. After experiencing the tepid "Golden Three Silver Four", textile bosses have pinned their hopes on the "Golden September......[ Read More ]
The quality of polyester staple fibers can be evaluated according to physical properties, chemical properties and appearance defects. Generally divided into excellent, one, two, three and so on. The classification items and specific indicators of various chemical fibers are different and are specified in the inspection standards.The physical and chemical properties of polyester staple fibers generally include the breaking strength and its coefficient of variation, elongation at break, linear density deviation, length deviation, ultra-long fiber ratio, long fiber content, number of crimps, and ......[ Read More ]
The long-awaited start, the traditional consumption season of the textile market finally arrived in September. At present, the operating rate of the industry has increased slightly, and the supply has increased. However, the overall downward wait-and-see attitude is obvious. The replenishment is mainly required, and the trading atmosphere in the market is light.So in the short-term, will the polyester filaments take advantage of the golden wind of Jinjiu and usher in a wave of rising prices?The raw material market is superchargedRecently, the PTA market has been stagnant, and the large-scale i......[ Read More ]
First, the process of polyester staple fiberThe polyester staple fiber is produced by feeding the polyester (PET) melt into the spinning machine; or using polyester chips as raw materials, drying and melting, feeding to the spinning machine, and then bundling, stretching, shaping, and crimping. , cut, package, and get polyester staple fiber.polyester staple fibers are flammable. The heat carrier biphenyl is flammable, explosive and toxic.Second, the safety points of polyester staple fiber2.1 Control the operation of slice drying and melt spinning to promote smooth operation.2.2 Screw extrusion......[ Read More ]
Recently, the “FZ/T 52022-2012 Industry Standard” formulated by Shanghai Defulun Chemical Fiber Co., Ltd. as the primary drafting unit has been officially implemented.This standard specifies the terms and definitions, product identification, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage requirements for flame retardant polyester staple fibers. According to the actual quality level of the current products at home and abroad and the needs of users, 14 physical indicators have been scientifically and scientifically formulated to improve the......[ Read More ]
In mid-August, under the guidance of the US plan to postpone or cancel some product tariffs, the polyester staple fiber opened up a wave of concentration, and the production and sales rate of many enterprises reached more than 500%.But at the moment, the polyester staple fiber market seems to be as calm as water, and what is the polyester staple fiber market? Will prices continue to rise?There is no obvious benefit at the cost end.At present, the PTA social inventory is estimated to be around 1.4 million tons, which is affected by the parking and maintenance of the installation. In August, the......[ Read More ]
In early trading today, PTA spot bids were less, MEG's internal discs were weakly adjusted, and the market talks were general. Today's prices are stable and small.On Monday, European and American crude oil futures were moderately higher. Yesterday, the PTA spot volatility rose. Today, the narrow range is mainly adjusted. The polyester raw material end is generally supported. The production and sales of polyester chips were relatively flat yesterday. It is expected that the polyester chip market will be adjusted mainly today.The PTA industry started at 90.13%, the polyester started load......[ Read More ]
The formation of polypropylene staple fiber cooling is generally as follows:The slow cooling of polypropylene staple fibers is beneficial to the improvement of crystallinity and the decrease of orientation, and the rapid cooling is favorable for the improvement of orientation and the decrease of crystallinity. However, the cooling is fast and the molecular orientation greatly accelerates the crystallization. This factor is often the main factor under the existing process conditions. Therefore, cooling too fast will result in a large degree of orientation and crystallinity. The crystallinity is......[ Read More ]
A few days ago, the China Textile Industry Federation held an analysis meeting on the economic operation of the textile industry in the first half of 2019. China Textile Research Institute of Industrial Economics introduced the operation of the textile economy in the first half of the year and the forecast of the trend in the second half of the year. The China Textile International Trade Office introduced the progress of Sino-US trade friction and its impact on the textile industry. China Textiles Federation Branch and Chemical Fiber Association The Cotton Textile Association, the Printing and......[ Read More ]
polypropylene staple fiber is a short fiber made by melt spinning, drawing, crimping, heat setting and cutting of polypropylene PP as raw material. In addition to the general spinning rheology considerations, polypropylene short fibers in the design of large spinning components must also pay attention to the following points:(1) The distribution density and distribution mode of the orifice of the spinneret should not only ensure the normal spinning without the phenomenon of injection, but also ensure the compact size of the spinneret and reduce the cost of the equipment under the premise of en......[ Read More ]
In these hot weather, the workers in the textile factory can't wait any longer. Many workers have taken time off to go home. Those homes are still in the first line far away from thousands of miles away: high temperature, holiday, and become the height of the recent circle of friends. Frequency words.High temperature, holiday, the load of the loom is reduced to 6-7%!“Many workers in the factory have asked for a holiday recently, so we are also preparing for a three-day holiday this week.” Recently, Mr. Chen, head of a textile factory in Wujiang area, said. According to the survey, at prese......[ Read More ]
polypropylene staple fiber requires one of the important parameters affecting the performance of the refrigerator when it needs to be refilled. So what is the nature of the frequency? We have studied this for a bit:If the frequency is too high, sufficient heat exchange between the working medium in the regenerator and the regenerator packing cannot be obtained, resulting in an increase in the irreversible loss of the regenerator, thereby affecting the efficiency of the whole machine.If the operating frequency is too low, a large regenerator is required to match the same cooling capacity.The po......[ Read More ]
