- How does static electricity affect polypropylene staple fiber? [3/30/2021]
- Polypropylene staple fiber is a kind of non-absorbent or very low water absorption, and it cannot be dyed and colored like other synthetic fibers such as polyester and eyeglass. Because of its high static electricity, it is difficult to perform processing such as clearing and spinning, which greatly restricts Based on its application, the high-efficiency, durable, practical antistatic agent and dyeable components were analyzed and screened. Polypropylene staple fiber is because polypropylene is located at the negative end of the fiber frictional charging sequence, so when it rubs with a fiber, It generates a negative charge by itself. This kind of fiber without modification treatment is prone to static electricity accumulation during use, and can cause many troubles in the processing process. Severe static electricity problems will directly affect the cleaning, carding and other processes, and it can't even be used for processing!......
- The use and construction technology of engineering polypropylene fiber [3/30/2021]
- Polypropylene fiber is a high-strength bundled monofilament fiber made with polypropylene as the main raw material and produced by a production process. Adding to concrete or mortar can effectively control the micro-cracks caused by concrete (mortar) solid plastic shrinkage, dry shrinkage, temperature change and other factors, prevent and inhibit the formation and development of cracks, greatly improve the crack resistance and impermeability of concrete, and impact resistance And earthquake resistance, it can be widely used in underground engineering waterproofing, industrial and civil construction engineering roofs, walls, floors, pools, basements, etc., as well as roads and roads and Note: The length range is 3-50mm, and can be produced according to customer requirements.Engineering polypropylene fiber is made of polypropylene through a special process. Commonly used polypropylene engineering fibers can be divided into two forms: monofilament and mesh. Reticulated fiber monofilament fiber Monofilament polypropylene fiber is a kind of high-strength polypropylene bundled monofilament fiber. Special surface treatment technology ensures that the fiber has the best dispersibility in the concrete and the bond strength with the cement body. Generally suitable for fine stone concrete. The appearance of the reticulated polypropylene fiber is that a plurality of fiber monofilaments are interconnected to form a network structure. When polypropylene mesh fibers are put into concrete, in the concrete mixing process, the transverse connection between the fiber monofilaments is destroyed by the rubbing and friction of the concrete itself, forming the fiber monofilament or the net structure to fully expand, thus achieving the quantity The effect of many polypropylene fibers evenly mixed into concrete.The quality of concrete mixed with polypropylene fiber is improved, and the comprehensive performance is improved. It has the characteristics of simple mixing process, low price and excellent performance.1. Anti-cracking: Mixing a certain amount of anti-cracking fiber into mortar/concrete will increase the anti-cracking ability by more than double. It can effectively improve the crack resistance of mortar/concrete caused by temperature stress, plastic shrinkage, dry shrinkage, etc. In the case of reasonable mix ratio and construction specifications, the appearance of cracks can be completely preventedTwo impermeability: can effectively improve and improve the anti-seepage and moisture-proof function of mortar/concrete. In general, adding anti-cracking fiber can improve the impermeability of concrete. It is an effective waterproof material.3. Impact resistance: After infiltrating the anti-cracking fiber, the impact resistance of concrete can be greatly improved.......
- Adding methods of polypropylene fiber in different fields [3/30/2021]
- Polypropylene fiber uses 100% polypropylene as raw material and is processed by a special process to form a high-strength bundle-shaped monofilament organic fiber. It has inherent strong acid resistance, strong alkali resistance, weak thermal conductivity, and extremely stable chemical properties.Polypropylene fiber can be used in different fields of construction engineering. Then, in different fields, the method of adding polypropylene fiber is different!1. Finishing and pressing: A pressing is performed immediately after the concrete is out of the mold, and the second pressing is completed before the initial setting of the concrete is finished. In addition, steel or iron trowels should be used as much as possible when pressing the surface. Because the wooden trowel is not smooth enough, it will pull out the fibers.2. Strength test: the addition of fiber will not affect the strength of concrete, but the strength test of fiber concrete should be carried out on the determined concrete mix according to the regulations before each project is used.3. Description: Fiber is only used as the "secondary reinforcement" of concrete, and its main function is to inhibit the occurrence of concrete cracks, improve the impermeability of the concrete matrix, and extend the service life of concrete, rather than "main structural stress reinforcement." Therefore, the incorporation of fibers cannot change the reinforcement ratio in the original design.Fourth, the feeding order and method: when using, add fiber and aggregates such as sand and stone at the same time, and then wet mix after adding water; it is better to add the fiber in the middle of the sand and stone at the same time as the sand and stone material, the effect is better.5. Forming and curing: Concrete mixed with fibers has no special requirements when forming, but it should be ensured that the concrete is fully vibrated. Concrete mixed with fibers has no special requirements during curing. It can be maintained as normal concrete, and cannot be mixed with fibers. And relax the early curing of concrete.6. Fiber concrete mixing: The mixing time is slightly longer than the mixing time of concrete without fiber by about 30 seconds to ensure that the fibers can be mixed evenly in the concrete.7. Slump adjustment: due to the thickening effect of fiber, the addition of fiber will increase the viscosity of the concrete mixture and slightly reduce the slump. Each project needs a different slump, so the slump should be adjusted through experiments before the project is used. If the slump cannot meet the construction requirements, the water consumption should not be increased to increase the slump, but plasticization should be used appropriately Or water-reducing agent to increase the slump to meet the requirements.......

- How to buy a sweater that can't afford the ball? [2/23/2021]
- How to buy a ball sweater? The key to not pilling is related to the length of the fiber and the weaving method. The fatigue resistance of the fiber is good, the hair balls are not easy to fall off, and there are many surface hair balls. The fiber is long and the degree of pilling is low. In addition, the thick and hard fiber is not easy to pilling.Pilling of clothes is affected by the characteristics of the fabric and cannot be avoided, but the degree can be controlled. Fine fibers are easier to pilling than thick fibers, and blended fibers are easier to pilling than other fibers. For example, a garment made of chemical fiber, wool, and cotton fiber blends is easier to pilling than a piece of pure wool.Fabrics that are easy to pilling: wool, nylon, polyester, thick wool knitted sweaters, etc.;Fabrics that are not easy to pilling: linen, cotton + polyester, silk, cotton, etc.......
- Read RCEP and China's textile industry in one article [2/2/2021]
- The world's largest free trade zone was bornOn November 15, 2020, the "Regional Comprehensive Economic Partnership Agreement" (RCEP) was officially signed. The 15 member states include the ten ASEAN countries, China, Japan, South Korea, Australia and New Zealand, covering a total population of 2.27 billion and a gross domestic product. A total of 26.2 trillion US dollars and a total export value of 5.2 trillion US dollars, both account for about 30% of the world. After 8 years of negotiation and consultation, the member states of RCEP have jointly promoted the world's largest free trade area from conception to reality. This is not only a landmark and important milestone for East Asia regional cooperation, but also an important engine for global economic growth. After the signing of RCEP, each member country still needs to complete their own domestic approval procedures. The agreement will take effect 60 days after at least six ASEAN member states and three non-ASEAN member states signatories submit relevant documents. As the world’s largest free trade arrangement, after RCEP takes effect, the number of final zero-tariff products in trade in goods will exceed 90%. The overall openness of service trade and investment is significantly higher than the original "10+1" free trade agreement, and high-level Modernization topics such as intellectual property, e-commerce, competition policy, and government procurement. As far as my country’s textile industry is concerned, RCEP will have a far-reaching positive impact on the industry’s expansion of the scale of foreign trade and the deepening of industrial chain supply chain cooperation within the region. China and RCEP member states Close textile and garment trade China has been in close contact with 14 other RCEP member countries in the textile and apparel trade. In terms of exports, ASEAN and Japan are our industry’s third and fourth largest export markets after the European Union and the United States. The total exports accounted for more than 20% of my country’s total annual exports of textiles and clothing (the total exports to the two major markets are approximately 60 billion U.S. dollars); South Korea and Australia, as important global textile and apparel consumer markets, have relatively sufficient purchasing power and are also important destinations for the industry's end product exports. In terms of imports, my country's annual imports of textiles and apparel from ASEAN exceed US$7 billion, accounting for about 30% of the industry's annual imports. ASEAN has become the largest source of my country's imported textiles and apparel. For example, my country imports a large amount of cotton yarn and clothing from Vietnam, and imports cotton knitted clothing from Cambodia. At the same time, Japan and South Korea are also important import sources for my country's functional fabrics, chemical fiber textiles and garments, and textile dyes. In addition, Australia and New Zealand also provide my country with a large amount of high-quality wool and other textile materials. According to China Customs statistics, in 2019, my country’s total textile and apparel import and export trade with other RCEP member states reached US$88.26 billion, accounting for approximately 28.8% of the industry’s total foreign trade that year. Among them, my country exported 76.19 billion US dollars of textiles and clothing to the aforementioned countries, accounting for 27.1% of our industry’s global exports. At the same time, my country imported 12.07 billion US dollars of textiles and clothing from these countries, accounting for 47.4% of the industry's total annual imports. China and Japan established a free trade partnership for the first time Achieve a historic breakthrough Speeding up the implementation of the free trade zone strategy is an important part of my country's new round of opening up. Up to now, my country has signed 19 free trade agreements with 26 countries and regions, including most RCEP member states. Among them, the China-New Zealand Free Trade Agreement took effect in October 2008, the China-ASEAN Free Trade Area was fully established in January 2010, and the China-South Korea and China-Australia Free Trade Agreements both took effect in December 2015. Through the signing of RCEP this time, my country and Japan have established a new free trade partnership. This is the first time that my country has signed a free trade agreement with the world's top ten economies, and it is also a major historic breakthrough for my country in implementing the free trade zone strategy. The scale of Sino-Japanese textile trade is expected to continue to expand Japan is currently the fourth largest export market in our industry. In 2019, my country exported 20.88 billion US dollars of textiles and clothing to Japan, accounting for approximately 7.4% of the industry’s total annual exports; during the same period, China imported 3.25 billion US dollars of textiles and clothing from Japan, accounting for approximately 12.8% of total global imports (the above data is based on the statistics of China Customs ). After the RCEP takes effect, most of the products that the industry originally exported to Japan generally face about 4%-11% of Japanese import tariffs. Except for a small part (masks, bedding filled with textile materials, etc.), the main exports are to Japan. The tariffs on clothing products (such as knitted sweaters, men’s and women’s tops, pants, suits, T-shirts, socks, dresses, etc.) will be reduced to zero within 16 years. Since Japan has signed free trade agreements with ASEAN, Vietnam, Thailand, Indonesia, India and other countries, the textile and apparel products of these countries can enjoy duty-free treatment to Japan. After the implementation of RCEP takes effect, it will help our industry gradually participate in international competition fairly in the Japanese market, reduce the export costs of foreign trade companies, and enhance the international competitive advantage of products. At the same time, the original import tax rate of 5% to 8% for the main categories of products imported by our industry from Japan will basically be reduced to zero in 11, 16 or 21 years. For example, the original 8% tax rate of textile machinery products such as shuttleless air-jet looms and flat weft knitting machines imported from Japan will be reduced to zero within 11 or 16 years after the RCEP takes effect, which will help the industry accelerate industrial innovation and upgrading And improve production efficiency. China-Korea Textile and Apparel Trade The tariff is optimal under the RCEP rules South Korea is an important trading partner of China's textile industry in East Asia, and one of the important export markets of my country's textile and apparel. In 2019, my country's textile and apparel exports to South Korea were 8.99 billion U.S. dollars, accounting for about 3.2% of the total industry exports that year. In the same year, my country imported US$1.502 billion in textiles and apparel from South Korea, accounting for 5.9% of the industry’s total annual imports. As far as South Korea is concerned, my country is also its largest source of textile and apparel imports, accounting for more than 1/3 of South Korea's total annual textile and apparel imports. The China-Korea Bilateral Free Trade Agreement came into effect on December 20, 2015. Various concession rules have been implemented for 5 years, and most textile and apparel products have enjoyed tariff reduction or exemption. The signing of the RCEP has little impact on the existing textile and apparel trade tariffs of the two countries, but there are still some export products with the best tariffs under the RCEP rules. From the list of clothing products with different tax rates under the various agreements listed in the table below, it can be seen that after the implementation of RCEP, my country’s chemical fiber knitted sweaters, men’s and women’s down jackets, women’s jeans, men’s cotton shirts and other products will all be based on the tax rate. The tax rate is halved to 6.5%. After the RCEP takes effect in the future, it will help expand exports of these products to South Korea. RCEP helps deepen the area Textile and apparel industry chain and supply chain cooperation The signing of RCEP is a boost to the international cooperation of the textile industry under the current situation where anti-globalization trends are emerging and the epidemic has hit the global textile industry chain cooperation. The member states of RCEP not only include the most important textile and apparel production bases in the world (China, ASEAN, Japan, South Korea), but also cover many important textile and apparel consumer markets in the world, and actively participate in regional industrial cooperation and construction. The efficient and coordinated textile and garment industry chain in the region adds assistance. After the RCEP takes effect, especially in terms of increasing exports to Japan, it will promote trade and investment interaction between our industry in the Lancang-Mekong countries and establish a more interconnected production capacity cooperation system, which will help accelerate the formation of a new development that promotes the mutual promotion of domestic and international double cycles. pattern.Through RECP, the market access of goods, services, investment and other fields among member states will be further relaxed, and customs procedures and technical standards will be gradually unified. By adopting regional rules of origin, it will promote the free flow of economic factors in the region and strengthen the membership. Cooperation in the division of labor will stimulate the expansion and upgrading of the consumer market in the region, and promote the further development of the industrial chain, supply chain and value chain in the region. RCEP’s cumulative rules of origin are more beneficial to companies The biggest achievement in the field of RCEP trade in goods is the provision of rules for the accumulation of origin in the region. Under the rules of origin in most bilateral free trade agreements in the world, goods entering another free trade partner country B from country A need to meet the value-added standards or production requirements in country A, and the goods are identified as originating from country A to enjoy the benefits of country B. tariff. The RCEP regional accumulation rule means that when goods enter from country A to another free trade partner country B, intermediate products of multiple contracting parties in the agreement can be used to meet the required value-added standards or production requirements, so that country A enjoys B The threshold of national zero tariff can be significantly reduced. A large-scale regional origin accumulation system like RCEP will make it easier for companies to obtain preferential tariffs. At the same time, it will have an impact on the company's procurement of raw materials and parts, industrial chain layout, and foreign investment decisions. After the RCEP takes effect in the future, when importing and exporting products that are included in the tariff reduction schedule and meet the standards of origin, they should actively apply for and issuance of certificates of origin, so as to enjoy tariff preferences and customs clearance convenience in time, and enhance the competitiveness of products in the international market .

- The reason for the rapid development of polypropylene staple fiber in the industry is actually because! ... [1/12/2021]
- 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 among the common fibers, and the sales volume has been increasing in recent years, which requires manufacturers to complete the output demanded by customers on time, so as to maintain the entire market for polypropylene filaments in short supply. Because polypropylene staple fiber itself has strong chemical resistance, except for strong concentrated nitric acid. Secondly, due to the unique wicking effect of polypropylene, the principle is that when the human body sweats, it can quickly transfer the sweat from the surface of the skin to the fabric, and evaporate, thereby keeping the bran dry and the clothes comfortable. This performance is also called unidirectional wetness.In the chemical fiber industry, the start is late, and people's acceptance of cotton fabrics and polyester fibers is also different. When polypropylene was officially put into industrial production in 1957, it was considered a rising star of synthetic fibers. Polypropylene is very strong, its initial modulus is also large, and its elasticity is excellent, so both the textile industry and the clothing industry have obvious breakthrough development. Clothes made of polypropylene fiber are relatively light in weight and comfortable to the touch.Taizhou Hailun Chemical Fiber Co., Ltd. production and operation: polypropylene staple fiber \ polypropylene staple fiber, hydrophilic polypropylene staple fiber, profiled polypropylene staple fiber, modified polypropylene staple fiber, pp polypropylene staple fiber, pp polypropylene staple fiber, profiled polypropylene staple fiber, Modified polypropylene staple fiber, polypropylene staple fiber for high-speed rail, various functional polypropylene staple fiber, hydrophilic polypropylene staple fiber, environmental protection polypropylene staple fiber, flame-retardant polypropylene staple fiber.......
- Enterprise survey reveals the truth about industry development, textile machinery exports increased by 17.26% year-on-year [1/12/2021]
- Since the beginning of this year, the sudden outbreak of the new crown epidemic has brought a major impact to the normal production and operation of the textile machinery industry: the main economic indicators have dropped sharply in the first quarter. Since the second quarter, with the successful control of the domestic epidemic, the production and operation order of enterprises has gradually returned to normal, the decline of industry economic operation indicators has narrowed significantly compared with the first quarter, and exports have remained flat year-on-year. Since the third quarter, the overall recovery of the industry has been obvious. Operating indicators have continued to recover, and the rate of decline has continued to narrow. Exports (including anti-epidemic textile equipment) have increased year-on-year, but the overall recovery of the industry is still facing certain pressure. The most pessimistic moment may have passedAffected by the epidemic in 2020, the global economy is facing difficulties in restarting and recovering from the crisis. Although countries have quickly introduced fiscal and monetary and regulatory policies in response to the epidemic, avoiding financial crises similar to 2008, the economic recovery is objectively Subject to the spread of the epidemic. In the first quarter of 2020, major economies other than my country fell relatively flat. In the second quarter, China's economy stabilized, while other economies around the world showed a sharp decline. In the third quarter, as the epidemic was initially controlled, the global economy showed a sharp rebound. Since October, with the second outbreak of overseas epidemics, the momentum of the economic rebound is expected to fluctuate. But overall, the forecast for the global economy has gotten rid of the most pessimistic situation in the second quarter. The IMF October forecast that the global economic growth rate in 2020 will be -4.4%, which is 0.5 percentage points higher than the forecast in June.On November 20, 2020, the latest "World Trade Indicators Index" released by the WTO was 100.7, a significant increase from 84.5 in August. World merchandise trade began to rebound strongly after the epidemic plummeted, but its sustainability remains to be seen. Corporate profits gradually recoveredAffected by the epidemic, various operating indicators of the textile industry fell sharply in the first quarter. In the second quarter, driven by the production of epidemic prevention materials and the recovery of domestic market demand, the economic operation of the textile industry has recovered under pressure. Production, investment, quality and efficiency The decline in operating indicators was significantly narrower than in the first quarter. The main economic performance indicators in the third quarter gradually improved, laying the foundation for a steady recovery. Although domestic and foreign market demand has picked up, it has not yet returned to normal levels. The production and operation pressures of enterprises have not yet eased, development confidence is still insufficient, benefits and investment have not reversed the negative growth trend, and the foundation for maintaining stable and positive development still needs to be consolidated.In the third quarter, the textile industry's prosperity improved significantly, and the recovery of production capacity utilization was accelerated. According to the survey data of the China National Textile and Apparel Council, in the third quarter of 2020, the textile industry prosperity index was 61.5 , an increase of 10.5 points from the second quarter, reaching the highest level since 2018. According to data from the National Bureau of Statistics, the capacity utilization rate of the textile and chemical fiber industries in the first three quarters reached 72.4% and 79.1% , respectively, up 2.1 and 2 percentage points from the first half of the year, but slowing down by 5.6 and 4 percentage points respectively from the same period last year. Textile machinery revenue decline narrowedIn the first three quarters of 2020, 639 textile machinery enterprises above designated size achieved operating income of 47.704 billion yuan, a year-on-year decrease of 16.04%, and the growth rate decreased by 19.073 percentage points from the same period last year. The decline in operating income in the first three quarters narrowed by 0.98 percentage points compared with the first half.From January to September 2020, the total profit of textile machinery enterprises above designated size was 2.987 billion yuan, a year-on-year decrease of 26.48%, and the rate of decline increased by 1.62 percentage points from the first half of this year. The operating income margin was 6.26%, a decrease of 0.33 percentage points from the same period last year; The loss of the enterprise was 524 million yuan, a year-on-year increase of 59.4%; the loss was 28.01%, an increase of 8.85 percentag......
