Polyester Fiber Is In Urgent Need Of Industrial Pformation.

Europe and North America call such textile products Technical Usage Textiles.

In 2010, the world's consumption textile products will reach 33 million 800 thousand tons.

L0 over the years, compared with the use of textiles, industrial textiles in Western Europe and North America are developing more rapidly.

In particular, the processing technology of polyester industrial yarn has made rapid progress. It has attracted a lot of attention both in terms of processing cost and fiber price performance, laying a solid foundation for the progress of industrial textiles.

At present, the fastest growing capacity is the mainland of China.

Industrial use in 2010

There are breakthroughs in development of long and short yarn.

The product development of polyester industrial yarn mainly includes four aspects. First, on the basis of the production of the polyester industrial yarn that has been industrialized, the production process and specification requirements are further optimized and improved, and products suitable for special fields are further optimized. The two is the modification of raw materials, including copolymerization modification and inorganic addition modification, so as to highlight a certain chemical or physical high performance characteristics; three, the polyester industrial yarn that changes the composition of raw materials, adopts new technology and new technology, produces relatively large changes in chemical and physical properties relative to polyester fibers, and four, from the perspective of application, sets out new products suitable for sustainable development, saving energy and reducing consumption, reducing environmental pollution, and products with more comprehensive market competitiveness than other chemical fibers.

Sinopec Shanghai Petrochemical polyester business department has researched and developed flame-retardant polyester and fiber products since 90s of last century.

After years of research, through the screening of flame retardants and process test, the first continuous industrial polyester plant with low cost, high stability and excellent product quality was produced in China.

Since twenty-first Century, the synthesis technology of new polyester PEN (polynaphthalene two formic acid glycol ester) has been mature and has begun to mass supply market.

The excellent performance of PEN is mainly due to its relatively high heat resistance and high chemical stability. It is an ideal material for tire cord manufacturing.

At present, there are only a few pet related enterprises in the world producing PEN, such as Japanese Imperial group, Dongyang spinning, MITSUBISHI chemical, Italy M&G, DuPont and Korea Kolon.

Under the premise of a substantial increase in production, the proportion of polyester staple fiber applied in industry is also increasing.

Polyester staple fiber for sewing thread has formed a good market system and basically replaced imported products.

In particular, the super high strength, high strength and bright sewing thread polyester staple fiber mainly based on Shanghai petrochemical and Yizheng chemical fiber has played a leading role in the development of the domestic short staple sewing thread Market.

In the field of nonwovens, high shrinkage PET staple is the main material of artificial leather base cloth. According to the manufacturing process of different artificial leather, the shrinkage rate of high shrinkage fiber can reach 80%, which is suitable for manufacturing high-density nonwoven products.

The rise of home textiles market is

In addition, developing new spinning technology and increasing the proportion of new spinning in production will be the focus of China's spinning technology progress and technological pformation in the coming period.

From the perspective of product market application, vortex spinning clean yarn quality has been well received, and has expanded in the field of knitted women's underwear and underwear spinning.

The raw materials suitable for vortex spinning such as polyester staple fiber exist considerable market with the improvement of spinning technology.

Jet spinning entered China as early as 1985, and its employment is 4~5 times more than that of ring spinning. This is of great significance for easing the current recruitment difficulties and shortage of labor in textile industry.

At the same time, the air-jet spinning process is shortened, production efficiency is improved, and the machine platform is reduced. Therefore, the energy consumption can be reduced by 20%~30%, and the plant area will be reduced by about 30%~40%.

The industrialization of functional polyester started in this century.

With the development of polyester production technology and the reduction of raw material cost, the application field of polyester super short fiber (main length 2 ~ 12mm) has been continuously explored.

In the field of papermaking, polyester super short fiber instead of some plant fiber is used to make some special paper, effectively improving the performance of special paper. In the field of road asphalt concrete, polyester super short fiber plays the role of bridging asphalt, improves the performance of asphalt road and improves the service life of asphalt road.

Functional polyester fiber mainly includes flame retardant, antibacterial, biodegradable, high elasticity, energy storage and so on.

The study started in the 80s of last century, but the real industrialization started from this century.

The nonwoven fabric of phosphorus flame retardant polyester staple is used for interior decoration of automobile, and flame retardant short fiber used for public occasions such as sofa, curtain and so on has been batch and standardized application.

Long term antibacterial polyester staple fiber production technology has been quite mature in recent years.

The antibacterial and deodorizing PET fiber made of highly efficient antibacterial agent or metal ions containing zeolite particles and fiber PET can effectively inhibit and kill microorganisms attached to the fiber surface. Zeolite particles also give fiber new characteristics, such as promoting blood circulation and accelerating wound healing.

Energy storage fiber (fluorescent fiber) is a new high efficiency self luminous material with rare earth ions as activator and alkaline earth aluminate as matrix.

This material has significant advantages such as innocuity, radioactivity and so on.

The polyester staple fiber with light storage function has wide application space in building decoration, pportation, military field, fire emergency, daily household life, low lighting and other fields.

New ideas of "environment-friendly"

From industrial production to date, polyester fiber has undergone several stages of large-scale production, differentiation, functional modification and environmental friendliness in the new era.

The development of "environment-friendly" polyester fiber products mainly focuses on four main objectives. First, the new technology and new technology are used to reduce energy consumption, material consumption and pollution of raw materials synthesis and the entire processing chain. For example, Shanghai Petrochemical adopts the new domestic polyester technology with low energy consumption. Compared with the traditional process, the energy consumption of the petrochemical industry is reduced by at least 30%. The two is the development of materials to replace petroleum resources to improve sustainability. Three, the fibers are modified from the perspective of textile raw materials to improve the processing performance and environmental protection performance; four is the recycling of fiber products.

In recent years, many European and American enterprises have increased the development and industrialization of biodegradable polyester, and some products have entered the commercialization stage.

China is still in the stage of R & D and small test, but in recent years, the joint research institutes such as Changchun Dacheng Group have made important progress.

Compared with traditional polyester, the main market targets and technological development of industrial polyester fiber product development are reflected in the upgrading of the existing textile market (household, automotive decoration, etc.).

Short fiber and profiled cross-section fiber are used in nonwovens; chemical modification makes fiber more environmentally friendly and more suitable for downstream users to improve efficiency, such as no heavy metal fiber, bulk dyed fibers, flame retardant fibers and so on; opening up and expanding new applications, polyester industrial yarn is mainly embodied in improving fiber performance, replacing and partly replacing nylon, viscose fiber and cotton, such as PEN/PET blending fiber; polyester BCF (expanded textured yarn) is a model of product development in non clothing field, especially in North American market; the development of melt blown and spunbonded technology brings hope to the development of polyester fiber in the nonwovens field; and guides the industrial market with high value-added and differentiated products, such as various functional fibers and new polyester fibers. For example, developing various special grades and improving some physical properties.
