The polypropylene staple fiber is in the number of tensile sisters because the polypropylene is relatively light, so the same day, polyester is much higher than the polyester, and the polyester single strength is also higher, so the tensile smector is lower than the polyester.After the stretching process and intensity relationship is stretched by polypropylene fibers, the increase in fiber power is mainly the result of the orientation of the fiber itself and the crystallinity increase. Generally, the number of draw ratios is increased and strong. It can be seen from the double-refractive index......[ Read More ]
On October 27, Vice President, China Textile Industry Association, President of China International Trade Promotion Committee Textile Industry Branch The role in addressing climate change.The meeting was hosted by the World Textile Information Network (WITN) headquartered in London, England, held on October 26-28, 2021, mainly discussed "how the current macro environment affects the next 10 years", and promotes more competitiveness, More toughness, in the future of customer priority and higher value. Thousands of industries from all regions from all regions of the world have viewed l......[ Read More ]
What is polyester staple fiber? What product characteristics are there a polyester staple fiber?Polypropylene staple fibers are mainly used in acupuncture carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, health care products, etc.The polypropylene staple fiber is made of polypropylene resin as the main raw material, which is made into color and colorless, defined, defined, and the length of fluffy fibers.Polypropylene staplet fiber product performance:1.Propylene staple fiber have superior humidification, flexibility, surfing, and superior thermal bonds.......[ Read More ]
Polypropylene staple fiber are fibers that are shorter than the length of the main fiber length in cotton fibers. Common polypropylene short fibers comprise a percentage of the total mass of the fiber, called short velvet. There are two main reasons for short fibers:The first is that the fibers are generated when it is grown, and the raw materials in the time of the cotton, especially shorter length (12 mm or less);The second is the damage of the fiber during the machining process, and the sequence produced by the combing process is turned off, combats and combed. The length of short fibers: f......[ Read More ]
The polypropylene staple fiber has a lot of excellent performance, mainly reflected in the following four aspects:First,polypropylene staple fibes have superior humidification, flexibility, networked and sortative, excellent thermally bondedSecond, polypropylene staple fibe is light, its density is 0.9 ~ 0.92 g / cubic centimeter, which is the lightest in all synthetic fibers, which is 2% percent than the polyamide fiber, 30% percent of polyester fiber, than adhesive The fiber is light 40%; the strength is high (the same as the mild and wet state), the wear resistance and elasticity ......[ Read More ]
The new round of industrial revolution sweeps the world, and the industry is re-divided into the wind. In the context of the new era, China's fibrous material manufacturing is a key transformation of the transformation and transformation upgrade. To this end, the national advanced function fiber innovation center needs to shoulder historical mission, maximize the innovation resources, aiming at new principles, new technology, new technologies, supplement shortals, exercise long chains, development of common key and competitive frontier technology research and development, forming productio......[ Read More ]
The epidemic wind of the textile and apparel fashion product has now started from the upstream fiber terminal. 2021YARNEXPO Autumn and Winter Yarn Exhibition, fiber new visits - Textile Material Innovation Forum held 3 topic forums, including Chinese fiber epidemic trends, green and sustainable fiber specials and domestic Leeder fibers special.Among them, in China's fiber epidemic, Wang Hua Ping, Professor Donghua University, has interpreted 2021/2022 China fiber epidemic trends; Sun Yanlin, chief engineer Tongkun Group, introduced the process route and research and development of hot and ......[ Read More ]
The use of polypropylene short fibers is very wide, and with the development of spinning machines, the development and application of polypropylene short fibers 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, ......[ 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 ]
