Fujian Province Eliminated Backward Production Capacity Last Year, Tannery 850 Thousand Mark

Reporters learned from the Fujian Provincial Commission of letters, last year, Fujian's industrial sector to eliminate backward and excess capacity targets and tasks were fully completed.

Fujian has actually eliminated the backward production capacity: 46 thousand and 150 tons of ferroalloy, 60 thousand tons of calcium carbide and 1 million 475 thousand tons of cement (including 875 thousand tons of clinker) and 359 thousand and 800 tons of paper making. To curry leather 850 thousand mark, printing and dyeing 15 million meters, lead-acid battery 525.88 million volts.

Last year, the Ministry of industry and Commerce issued the province of Fujian. Industry The goal of eliminating backward production capacity is: 45 thousand tons of ferroalloy, 50 thousand tons of calcium carbide, 1 million 400 thousand tons of cement (clinker and mill), 300 thousand tons of paper making, 600 thousand sheets of leather, 450 kilovolt ampere of lead-acid batteries (plates and assemblies). Fujian The actual elimination of backward production capacity is: 46 thousand and 150 tons of ferroalloy, 60 thousand tons of calcium carbide, 1 million 475 thousand tons of cement, including 875 thousand tons of clinker, 359 thousand and 800 tons of paper, 850 thousand sheets of leather, 15 million meters of printing and dyeing, and 525.88 kilovolt ampere of lead-acid batteries.

Natural leather is flexible, breathable, wearable, resistant to folding and beautiful, and is easy to modify and sculpt. Therefore, it is a necessary material for high-grade leather shoes. But its physical properties are relatively poor, thick and uneven, alkali resistant, and expensive, with limited resources and low utilization rate, and the manufacturing process is not environmentally friendly. Harmful substances such as chromium and formaldehyde are gradually replaced by artificial leather in shoe leather, luggage leather, ball leather, furniture leather, automobile upholstery leather and other fields.

In recent years, the high quality artificial leather made of two-component spunbonded nonwoven superfine leather fabric has been formed, which has a three-dimensional structure similar to the natural leather. It has the characteristics of light weight, high strength, uniform quality, aging resistance, abrasion resistance, anti disturbance, soft handle, good processing ability, high cutting rate and variety variety. It is superior to leather in resilience, strength, waterproofing, mildew resistance, cold resistance and wear resistance, and has become an ideal substitute for natural leather.

China is the world's largest producer and consumer of synthetic leather and synthetic leather. It has developed to 80% of the world's market share and ranks first in the world. But at present, the production capacity of our ultra fiber leather is about 120 million square meters, accounting for only 3% of the total leather. Compared with the proportion of 85%~ 90% in Japan's Microfiber artificial leather, our country is far apart from it.

It is understood that at present, domestic "ultra fiber leather" manufacturing technology has matured, with Shanghai Huafeng, Shandong Tong Da, Yantai Wanhua, Wuxi double elephants and Zhejiang Hexin as the representative of the super fiber leather enterprises, all adopt the two step production process of short fiber + loose, carding + acupuncture to produce ultra-high fiber leather.

The enterprises represented by Ji'an Sanjiang and Langfang spinning new yuan adopt the one-step two-component microfiber spunbonded and spunlaced process equipment technology developed by Dalian Hua Lun Chemical Fiber Engineering Co., Ltd. to produce super fiber leather base cloth. Compared with other domestic enterprises, the process flow is short, investment is low, energy consumption is low, pollution free, and the product is strong. At the same time, it also has a considerable advantage in the price of equipment.

"Microfiber spunbonded spunlaced nonwovens production line has only 4 production lines in Jiangxi, Ji'an, Sanjiang, Langfang, China textile, Xinjiang, Tianjin, and Henan, and the annual production capacity is not more than 7000 tons. Only Germany, Germany and Korea BAIKSAN have entered commercial production, and the scale and quantity of production can not meet the market demand. Huang Youpei, general manager of Dalian Hua Lun Chemical Fiber Engineering Co., Ltd.

What is a two-component spunbonded nonwoven spun leather fabric? In fact, two component superfine fiber spunbonded spunlaced nonwovens are produced by combining filament spunbond with spunlace. A new type of nonwovens made of two kinds of polymer PET/PA6, which is produced by conjugate spinning, airflow drafting, mesh spreading, water stab, drying, calendering and winding, is used. The main technology is the spunlaced stripping technology in two-component spunbonded nonwovens. The hollow orange petal microfiber filament has been opened and consolidated by posterior spunlace, forming two component superfine fiber spunbonded spunlaced nonwovens.

"The production of high-grade artificial leather with superfine fiber spunlaced nonwovens as raw material, due to its formation of a more compact and disordered three-dimensional structure than ordinary synthetic fibers, the leather made can achieve a false degree of authenticity, and greatly improve peel strength and fastness, overcome the shortcomings of natural leather leather which is easy to mold, smell, embrittlement and strength, and achieve the excellent performance of natural leather." Huang Youpei said. Therefore, microfiber spunlaced nonwovens can meet the needs of shoe leather, luggage leather, sofa leather, automotive interior leather and so on, providing good foundation and development space for garment leather, and upgrading products in the application field of non-woven fabrics.

In 2008, the first two component hollow orange spun Spunlaced spunlaced nonwovens production line, designed and manufactured by Dalian Hua Lun Chemical Fiber Engineering Co., Ltd., was successfully launched in Ji'an, Jiangxi. Li Feng, general manager of Jiangxi Ji'an Sanjiang microfiber nonwoven company, said that leather products developed with superfine spunbonded spunlaced nonwovens, many of which exceed the properties of leather, have a good market prospect in shoemaking and leather clothing. At present, the company has been working with some shoemaking enterprises and developers to launch the series of products of high-grade microfiber nonwovens, and accept a new round of inspection in the market.

At present, Dalian Hua Lun Chemical Fiber Engineering Co., Ltd. adopts two component superfine fiber spunbonded Spunlaced Nonwovens Technology and equipment technology, has independently developed, designed and manufactured 4 two-component superfine fiber spunbonded spunlaced nonwovens production line, the production line has achieved industrial production, production capacity of 7000 tons / year, products are mainly used for shoes lining leather, artificial suede leather, wall cloth, tablecloth, wipe cloth and other fields. After the product was put on the market, the users responded well, with high strength and good evenness.

Scientific and technological innovation depends on scientific research strength and flexible innovation system. "Over the years, we have made great efforts to develop two-component leather core, two-component spunbonded nonwoven spun non-woven leather fabric equipment and technology, and have made bold innovations for a long time. They have been widely used in the field of microfiber leather, and have won high praise from tanning enterprises. At the same time, they have received strong support and cooperation from Langfang Xinyuan yuan and Tianjin University of Technology. Huang Youpei said. They rely on innovative ideas. They combine the scientific research institutes and enterprises closely with the market mechanism to gather innovative resources and achieve innovation and development.
