- What is the production process of polypropylene staple fiber? [7/11/2023]
- The production process of polypropylene staple fiber seems simple and convenient, but the actual operation is slightly careless, which has a greater impact on its production products, such as the problem of excessive elongation of polypropylene staple fiber, excessive elongation of polypropylene staple fiber will bring a lot of harm, and blending will also affect the strength of yarn, so, the following to understand what categories of polypropylene staple fiber can be divided into!Polypropylene staple fiber features: acrylic short fiber density is small, light texture, can float on the water; Acrylic yarn has high strength and strong tensile strength. Acrylic fiber acid and alkali resistance, seawater immersion worry free; Acrylic fiber hygroscopicity is small, almost no hygroscopicity; Polypropylene staple fiber is an environmentally friendly and pollution-free product.Polypropylene staple fiber is made of polypropylene as raw material, through melting, stretching, spinning, cutting and other processes. In the process of making polypropylene staple fiber, anti-aging masterbatch, flame retardant masterbatch and other functional masterbatch can be added according to needs to improve the performance of acrylic staple fiber. Polypropylene staple fiber for felt is specially used for felt production of acrylic staple fiber for filter material.The strength difference of yarn after blending appeared in textile yarns, such as pure acrylic fiber quality index 2808, acrylic fiber 50% cotton blend index 1950, acrylic fiber 50% cotton blend index 2193, and kapokay quality index 2336. The above data show that the strength of pure spun acrylic yarn is much higher than that of cotton, but after blending with cotton, it is not higher than kapok. This may have something to do with the inhomogeneity in the mix of polypropylene staple fibers and cotton, but it is also related to the difficulty of controlling the elongation of acrylic staple fibers, so manufacturers seem to be trying even if they care about simpler processes.Polypropylene staple fiber according to natural fiber specifications can be divided into cotton type, wool type, carpet type and medium long type of short fiber. They can be spun either pure or blended with different proportions of natural fibers and other fibers into yarn strips, fabrics, and felt. For example, the general grade of asphalt carbon fiber is mixed in a ratio of 8:2 to carbon fiber with a length of 150mm, a diameter of 15m, a strength of 800MPa, and a modulus of 41GPa, and the reinforcement of composite materials such as cement and magnesium aluminum alloy uses fabrics and short fibers woven into various shapes.......
- The production enthusiasm of enterprises in the traditional off-season is OK [7/11/2023]
- July is the traditional off-season, and the orders of enterprises will continue to follow the decline, and the flow of people in the grey fabric trading market is less.According to the survey, the number of orders received by textile enterprises has indeed declined from the previous month, mainly in the state of small orders constantly and large orders occasionally. Affected by the off-season, the grey fabric inventory of weaving factories is still rising, according to the data of the silk city network, the current grey fabric inventory of weaving enterprises in Shengze area is about 36 days, up 1 day from the beginning of June.However, from the perspective of the opening probability of weaving enterprises, the production enthusiasm of enterprises is OK, and has not been affected by the off-season and has declined significantly. According to data from the silk city network, the current opening rate of weaving enterprises in Shengze area is 70.5%, down 4.5% from the beginning of June, up 4.5% year-on-year. The comparison of the above two groups of opening rates can be seen that today's weaving load is relatively high in recent years. Even some enterprises are still in a full open state, and there is still no plan to decline in July."The factory is running at 100 percent, the same as in June," said Mr. Button, who specializes in Taslon and Oxford fabrics.The main reason to support the high load of the factory is that the boss of the cloth is expected to be higher in the traditional peak season in the second half of the year, even if the gray cloth delivery speed has slowed down, some factories have entered the inventory state, but in order to prepare for the second half of the year, the willingness to start is not obvious. In the traditional off-season, the price of grey cloth is difficult to firm, with the weakening of the market has loosened.The weaving load almost depends on the number of orders and market trends. The factory holiday is also more cautious than last year, last year under the impact of the epidemic, the factory holiday is more, and this year obviously feel the holiday is reduced.Although July and August is the off-season of the year, the current temperature is not high, and workers are not willing to take a holiday, but if the temperature is too high in the later stage, they will consider putting a few days off to reduce the boot load.At present, driven by the cost, raw material prices continue to rise, many downstream factories catch up in the price node before the stock, and the shipment situation of the factory has improved, Friday polyester filament sample enterprise production and sales rate of 176.9%, individual higher production and sales of about 300%, leading to a small wave of high tide, whether it is really the market is coming, or speculation, remains to be verified. In general, this year's price compared to last year's price is still a lot lower, but this year's textile and clothing business is more difficult than last year, overcapacity, customers do not want to take over the goods, fabrics can not sell on the price, inventory accumulation, financial pressure, can only be helpless to sell goods at lower than the market price, resulting in a collective decline in fabric prices.......

- Downstream terminal textile industry off-season drag demand market [7/4/2023]
- According to the commodity market analysis system of the business community, domestic polyester filament prices rose first and then fell in June, as of June 29, the mainstream polyester filament factories in Jiangsu and Zhejiang regions, polyester POY(150D/48F) quote in 7350-7550 yuan/ton, polyester DTY(150D/48F low bullet) quote in 8700-9250 yuan/ton, Polyester FDY(150D/96F) is quoted at 8000-8250 yuan/ton. Boosted by good costs, boosting polyester prices, but with the deepening of the off-season phenomenon, the market is weak under the lack of demand.In June, the supply and demand of crude oil was not significantly driven, and the oil price fluctuated between ranges. As of June 28, the settlement price of the main contract of WTI crude oil futures in the United States was $69.56 / barrel, and the settlement price of the main contract of Brent crude oil futures was $74.24 / barrel. As of June 27, the settlement price of the main contract of WTI crude oil futures in the United States was $67.70 / barrel, and the settlement price of the main contract of Brent crude oil futures was $72.51 / barrel. However, in June, PX large plants unplanned production cuts caused concerns about PX supply constraints, forming a positive boost. In June, the decline of the domestic PTA market slowed down, mainly shock adjustment, as of June 29, the average price of the spot market in East China was 5600 yuan/ton, down 1.08% from the beginning of the month, down 16.82% year-on-year.The downstream terminal textile industry off-season drag down the demand market, textiles, clothing new orders are weak, individual weaving factories shut down or reduce the opening probability, Jiangsu and Zhejiang comprehensive opening probability near 60%. Orders are insufficient to follow up, enquiries are not strong, and the overall market turnover shows a narrow downward trend. The foreign trade market also performed poorly, customs data show that from January to May, China's cumulative textile and garment exports of 118.2 billion US dollars, down 5.3%, of which textiles fell 9.4% and clothing fell 1.0%. Textiles fell 14.1 per cent in May from a year earlier, while clothing fell 12.4 per cent.Business analysts believe that the current overseas PX supply of raw materials has been restored, and the new domestic devices have successfully discharged, and the PX supply tends to be relaxed. The PTA market faces destocking in June, but the domestic PTA device restarts more in the second half of the year, and the current PTA device load is increased to more than 80%, and it is expected to enter the accumulation stage after July, so there is a weakening risk at the cost end of polyester. In addition, although the current inventory of most manufacturers of polyester filament is at a low level in recent years, but the next 7-August high temperature weather, weaving and other downstream areas of the open probability still has a declining trend, polyester industry is expected to heat up. On the whole, the market price of polyester filament in July will fluctuate and run weakly.......

- The production of staple fiber has increased [6/27/2023]
- According to the commodity market analysis system of the business community, last week (June 19-25) the domestic polyester staple fiber market was temporarily stable, and the average factory price was 7376 yuan/ton as of June 25, which was flat compared with the beginning of the week. With the repair of processing fees, most of the production reduction devices have been returned successively, and the production of new staple fiber devices has been put into operation, and the current output of staple fiber has increased.At the same time, the downstream is in the traditional off-season, the demand performance is weak, and the just-needed procurement is mainly. Some cotton mills have parking holidays for several days during the Dragon Boat Festival holiday, especially in Shandong and Hebei. And July-August is often accompanied by the phenomenon of the decline in the construction of yarn mills and weaving mills due to high temperature lack of work or power rationing, and the demand will be further reduced and the pressure on the reservoir will increase.However, recently, the large raw material PX plant has fallen, resulting in a fall in the on-load, PX supply has been tightened, and short-term prices may be stronger. In this boost, the domestic PTA spot market showed a volatile upward trend, as of June 25, the average price of the spot market in East China was 5690 yuan/ton, up 0.26% from the beginning of the week, forming a favorable support for polyester staple fiber.Business analysts believe that the cost support of staple fiber factories is still there, and prices are still relatively strong. However, with the gradual deepening of terminal weakening, the performance of the short fiber market is weak, and the risk of falling is vigilant.......

- The recovery in demand during the off-season is limited [6/20/2023]
- According to the business community commodity market analysis system, this week (June 12-16) domestic polyester filament prices fell slightly, as of June 16 in Jiangsu and Zhejiang mainstream polyester filament factory, polyester POY(150D/48F) quote in 7500-7800 yuan/ton, Polyester DTY(150D/48F low elastic) quote at 8850-9350 yuan/ton, polyester FDY(150D/96F) quote at 8050-8350 yuan/ton.U.S. retail sales unexpectedly rose in May, supported by positive jobs data. In addition, China's refinery processing volume has increased significantly, and the oil market has fluctuated upward. As of June 15, international crude oil futures rose. The main contract for U.S. WTI crude oil futures settled at $70.62 per barrel, while the main contract for Brent crude oil futures settled at $75.67 per barrel.In terms of PX, the unplanned decline made the monthly supply and demand balance tight, and the price strengthened. The spot processing fee of squeezed PTA is below 200 yuan, so the enthusiasm of PTA plant construction is reduced, and the current industry construction is near 73%. Affected by the PTA rebound, as of June 16, the domestic PTA market price in East China was 5737 yuan/ton, up 2.52% from the beginning of the week (June 12).With the improvement of the atmosphere at the cost end, the replenishment action of downstream enterprises has increased. However, under the traditional off-season of high temperature and high humidity, terminal demand is poor, cash flow is weak, inventory accumulation, and the start of weaving factories in Jiangsu and Zhejiang fell below 60%. And from the recently announced textile and clothing export data is also relatively weak, the US dollar in May textile and clothing exports of 25.32 billion US dollars, down 13.1%, down 1.3%, of which textile exports of 12.02 billion US dollars, down 14.2%, down 5.6%, clothing exports of 13.3 billion US dollars, down 12.2%, an increase of 3%.Business analysts believe that the recent crude oil prices are still expected to move up, a number of domestic PX plants unplanned production cuts are still fermented, and cost support is strong.

- Textile high-tech, warm guard the astronaut's "way home" [6/13/2023]
- On the early morning of June 4, the re-entry module of the Shenzhou 15 manned spacecraft successfully landed at the Dongfeng landing field. Professor Chen Li of the Textile Future Technology Research Center of Tianjin University of Technology led the team to create a multi-dimensional woven structural reinforcement material with a high temperature resistance of more than 2000 degrees Celsius for Shenzhou 15 return capsule, and a ground thermal device designed by Professor He Yang of Beijing Institute of Fashion Technology for the astronauts after exiting the capsule... A series of textile high-tech, warm guard the astronaut's "road home".In order to ensure the smooth return of the astronauts, Professor Chen Li led the team to use the original multiple coupling weaving technology of Tianjin Polytechnic University to "tailor-made" multidimensional braided structural reinforcement materials with high temperature resistance of more than 2000 degrees Celsius for the Shenzhou XV re-entry module, which accurately met the requirements of "high temperature ablation resistance, strong impact resistance" for the protective structural composite materials of the key components of the re-entry module. Make new contributions to the safe landing of astronauts.The composite materials research team led by Professor Chen Li has long been engaged in the basic research and technology development of multi-dimensional braided materials and their composite applications in the aerospace field. Relying on the university's national "double first-class" construction discipline and "High Performance fiber and textile Composite material preparation Technology" national and local joint engineering research center, key laboratory of the Ministry of Education, Engineering Research Center of the Ministry of Education and other national and provincial platforms, Tianjin Polytechnic University has built an advanced textile composite rapid response research platform integrating material design, multi-dimensional weaving, liquid forming, performance characterization, etc. It has obvious characteristic advantages in three-dimensional weaving of complex special-shaped composite components, and its scientific and technological achievements have reached the international advanced level, winning 2 second prizes of National science and Technology Progress and 7 first prizes of provincial and ministerial science and technology. The multi-direction woven reinforced textile composite material developed was successfully applied to the "Shenzhou 7" to "Shenzhou 15" return capsule, and has continuously contributed "heavenly power" to China's aerospace industry.After landing, the astronauts Fei Junlong, Deng Qingming and Zhang Lu all got out safely. After each astronaut exited the capsule, the staff immediately put on blue "warm clothes" for them.Astronauts stay in orbit for a long time, and can not immediately adapt to the Earth's gravity after returning to the ground. This "outfit" is the astronaut ground thermal device, which can provide effective protection for the health of the astronaut.The astronaut's "warm suit" was designed by Professor He Yang, former director of the National Costume Museum of Beijing Fashion Institute. Professor He Yang served as the sleeping bag pattern and cabin overalls color designer for the astronauts of the "Shenzhou 7", "Shenzhou 9", "Shenxi", "Shenzhou 13" and "Tiangong 2" missions, and began to design patterns and patterns for the cabin sleeping bags from the "Shenzhou 7". "At that time, the concept of 'auspicious clouds flying in the sky' was used, the sleeping bag had various cloud patterns, and the 'God 15' used the ground warm equipment of the 'God 13' and 'God 11'." I hope that through the design of affinity, astronauts can feel the warmth of 'home' when they go through a long flight and land safely in the motherland."At the wonderful moment when astronauts return to Earth, this device has the dual function of keeping warm and showing the national image. How to integrate traditional cultural elements with aerospace high technology and the heroic temperament of astronauts, and use color and graphics to form a peaceful visual atmosphere, requires a lot of research and attempts in the design.He Yang's design team finally chose the Han and Tang patterns for redesign, with a magnificent and elegant design style to highlight the heroic posture of Chinese astronauts. The main color of the pattern is blue, which is the special color of China's aerospace industry. The typical patterns in bronze mirrors, fabrics and paintings of Han and Tang Dynasties, such as tuanhua and Xiangyun, are extracted, and the patterns are organized by the method of four continuous traditional patterns. The strict geometric structure is composed of rational order, in line with the rational characteristics of space science and technology, and the individual flowers and clouds are rich in changes, full of perceptual elegance and interest, perfectly integrated with the image of China's space science and technology.The floor warmer consists of a sleeping bag and blanket. The sleeping bag will hold the astronauts in their spacesuits, while the blanket will provide more warmth and protection. The sleeping bag was specially shaped to fit the natural curvature of the astronaut in the armchair; The use of outdoor sports professional fabric, to achieve wind insulation effect. In order to ensure the safety and convenience of astronauts, the functional structure of the sleeping bag has been uniquely designed, and the fabric and sewing technology have been strictly selected to ensure the environmental protection and safety of the process.On the front of the blanket, the logo of the Astronaut Center of China and the ACC font are regularly combined together, and the auspicious cloud pattern of the Tang Dynasty surrounds the area. It has the sense of soaring upward and the charm of traditional patterns. Moire, font, logo successively size progressive, highlighting the space image elements, with a rich sense of hierarchy. On the reverse side, floral pattern is combined with logo and font. Double-sided design can increase the warmth function, ensure the beauty and practicality.The sleeping bag is composed and bright blue, the front chest has the national flag and space mission logo, and the inside is the blue-white flower pattern of the Tang Dynasty. Style front split, pull lock open and close, easy to wear and take off. The sleeping bag adopts a three-dimensional cutting structure, which is suitable for the astronauts in the state of the recliner device, and is more comfortable and fit.It is reported that this project is also a major practice of the Beijing Institute of Fashion Technology's doctoral project "Saving inheritance and design innovation of Chinese traditional Costume Culture". The project aims to provide talents and intellectual support for the protection and promotion of Chinese traditional clothing culture and the enhancement of the international competitiveness of the clothing industry.......
- What is the antistatic property of polypropylene staple fiber? [6/7/2023]
- What is the antistatic property of polypropylene staple fiber?There are many types of polypropylene staple fibers in the use of antistatic agents, simply divided into several types with ionic properties, and these types have their own advantages and disadvantages. Firstly, the antistatic effect of anionic type is poor, and its water solubility is good, easy to be washed off, so the durability is poor; The cationic type has good antistatic effect and good smoothness and absorption. However, toxic and corrosive, most of them are used for surface finishing, although the amphoteric type has the antistatic properties of the above two, it is easy to fade at high temperatures and the price is more expensive.Then there is the non-ionic type: good durability, low toxicity, suitable for fiber blending, but it will affect the dyeing of the fiber. Based on the above points, a compound antistatic agent was prepared. In order to facilitate production and disperse the antistatic agent evenly, the antistatic agent was first processed into masterbatch. The antistatic masterbatch is made by twin-screw extruder granulator. The antistatic agent, dispersant and carrier are mixed and coated in a certain proportion. In this way, the antistatic property of the polypropylene staple fiber produced has been greatly improved.Taizhou Hailun Chemical Fiber Co., LTD., formerly known as Taizhou Chenguang Synthetic Fiber Factory, was founded in 1995.

- We will remain patient and focused and work for a sustained overall improvement in economic performance [6/7/2023]
- On the whole, short-term fluctuations do not change the trend of economic recovery. We must not only have the confidence to do a good job in economic work, but also be fully aware of the difficulties and complexities that economic recovery may face, and remain patient and focused to promote sustained and overall economic improvement.The purchasing managers' index for manufacturing continued to fall. According to the latest data from the National Bureau of Statistics, the manufacturing PMI fell 0.4 percentage points to 48.8% in May, which is larger than the seasonal average, and has been running below the line of expansion and contraction for two consecutive months. The non-manufacturing PMI came in at 54.5%, down 1.9 percentage points from the previous month and down for two consecutive months. As a leading indicator of economic operation, the fall of PMI indicates that insufficient aggregate demand is still a prominent contradiction facing economic operation, reflecting the complexity of economic recovery and the urgency of stabilizing domestic demand.Since the beginning of this year, China's society has fully returned to normal operation, the triple pressure of shrinking demand, supply shock and weakening expectations has been eased, and economic development has shown a good trend of recovery. However, as the meeting of the Political Bureau of the Central Committee put forward, "the current improvement of China's economic operation is mainly restorative, the internal impetus is not strong, and the demand is still insufficient." In May, with the concentrated release of the previous backlog of demand, the short-term market demand momentum weakened. As can be seen from the PMI data, the economic recovery has obvious structural differentiation: the recovery speed of demand lags behind the recovery of supply; The non-manufacturing sector, especially the service sector, recovered steadily, but both production and demand in the manufacturing sector slowed down. The PMI of large enterprises rose to the critical point, and the prosperity of small and medium-sized enterprises was still weak.Our country faces a complex and severe environment for development, with periodic, structural and institutional incongruities coexisting, and international risks and challenges coexist with domestic difficulties. Internationally, the prospects for a strong recovery in the global economy remain dim amid high inflation, rising interest rates and heightened uncertainty. Slowing global growth is also likely to keep external demand under pressure. On the domestic front, people's income is still expected to recover, there is great pressure on young people to find jobs, and the sustainability of the momentum of consumption recovery faces challenges. There are still constraints on government investment to leverage social investment.Restoring and expanding demand is the key to a sustained recovery in the current economy. Data show that in May, the proportion of manufacturing enterprises reflecting the lack of market demand reached 58.8%, hitting the highest value since the survey. The decline in foreign demand accelerated, and the new export orders index was 47.2%, down 0.4 percentage points from the previous month. Reflecting the lack of market demand, the proportion of non-manufacturing enterprises was 52.6%, ending the trend of four consecutive months of decline, and reaching a new high this year. Macro policies should be more forward-looking, targeted and coordinated, take comprehensive measures to release the potential of domestic demand, and promote positive feedback between supply and demand.Consumption is the ultimate demand and the basic driving force for economic development. We should give priority to restoring and expanding consumption.
