"Wu He" Takes Off With Differentiated Wings.

Can not erase the polyester fiber memory

If clothing It is a kind of memory, a vivid and vivid record of a country, a society and an era. So, all kinds of fiber fabrics we are exposed to are the soul of this record. When it comes to the history of Dacron, we will also have to mention the name "Dacron", which once imprinted on our life.

"Dacron" was first seen in various department stores in urban and rural areas in the late 60s of last century. In the age of lack of material conditions, as a new fiber fabric product, it was first used for all kinds of men and women. shirt Sell. When we first appeared, people everywhere poured their shirts into this kind of shirts made of smooth and smooth new materials. Coupled with its very attractive name, "Dacron", there are many consumers coming to buy it.

However, it is understood that through this "first generation". Polyester clothing The old comrades introduced. In fact, soon after wearing this shirt, it was found that it was not cool. Especially in hot summer and hot weather, because of poor permeability, it feels like wearing a piece of plastic film. Sweat from human body can not evaporate at all. Some people used to joke half that it was better to call it "hot" than "Dacron". However, the advantages of "Dacron" lie in its high crease resistance, that is to say, the shirts made of it can always be smooth and smooth. Unlike cotton, it is easy to wrinkle. Besides high resistance to wrinkle and good shape, the abrasion resistance of "Dacron" is also very good. In common saying, it is durable. In that era, it had an unparalleled advantage.

Later, around the middle of 70s, people blended polyester and natural cotton fibers to make up for each other and produce "polyester cotton". This material not only keeps the advantages of polyester, but also brings out the advantages of cotton fiber's permeability and moisture absorption. The new material made by this way is durable and durable, and has good permeability and hygroscopicity. This is the second generation of "Dacron" clothing that was popular throughout the country in the late 70s and was expensive at that time. In those days, having a "Dacron" shirt was absolutely a symbol of "fashion" and "foreign flavor". It is said that some beautiful women would rather eat less food and save money from the teeth to buy a "Dacron" shirt.

It can be said that polyester fiber clothing in the last century, Chinese people's clothing history has left a thick ink.

Scissors and disorderly polyester and cotton relations

Since September 2010, China's polyester industry, which has been dormant for ten years, has finally ushered in a long awaited spring. Since the beginning of the month, the price of polyester products has been rising continuously, and the price has been increasing repeatedly. But in fact, cotton prices, which had been soaring at that time, were considered by most people in the industry to be the main reason for the price rise of polyester products.

As a substitute for cotton, various chemical fibers have actually entered China more and more. Spin Garment industry. At the same time, as China's polyester fiber accounted for more than 80% of the use of chemical fiber in all textile industries, the price of polyester also rose linearly with the rise of cotton prices. However, this is still the leading role of the business interests.

The reasonable price difference between cotton and Dacron in the textile industry should be between 10000-12000 yuan per ton. But in March 2011, for example, the price of cotton is about 31000 yuan per ton, and the price of polyester staple fiber has been maintained at about 15000 yuan per ton, though it has risen sharply. The difference between them is as high as 16000 yuan per ton. Textile and garment industry is facing the pressure of increasing product cost and pursuing enterprise profits. It is also natural to choose polyester as a substitute for cotton. In other words, the soaring cotton prices have made the downstream processing enterprises overburdened. Some companies that have signed orders have to perform the price before the price rises, but some small and medium-sized cotton spinning enterprises have chosen to stop production or cut production to pass the "cold winter". As a substitute, after the price of cotton rises, processing enterprises will increase the proportion of polyester and viscose fiber to avoid the risk of the market.

It was also in the afternoon of 2010 and the group's polyester production plant began to build and set up equipment, began trial production in mid May 2011, and made some equipment rectification on the way, so it did not start production until July 1st. For the positioning of products, there is a clear and clear thinking in the afternoon and decision-making level. That is to make high-end differential polyester staple fiber instead of cotton and bottle with low technical content and low added value.

However, at noon, the new polyester plant is facing pressure and challenges from all sides. First of all, the polyester industry in China will have about 4 million tons of new polyester production capacity, and the total production capacity of polyester will reach 33 million 400 thousand tons. Second, the price of cotton that can control the price of polyester fiber has shown signs of a sharp decline. In addition, the pressure of money also makes people sweat a lot for the afternoon and polyester. Liquidity is not counted. Noon polyester fiber The factory has invested 80 million in civil engineering and equipment, of which about 20 million of loans.

Faced with the severe market environment, how to make the difference between the meridian and the polyester staple fiber and how to open the market? In the wake of the wave, Joe satellite has always insisted on his optimistic judgement of the prospect of differential polyester staple fiber. In his view, the differential polyester staple industry is a very promising field. Polyester is gradually replacing cotton. This is an inevitable trend, but the added value of conventional polyester is too low, and now the competition has reached the level of white hot. In general, the polyester enterprises are very large in volume, hundreds of billions or even tens of billions of investment, and profits are very thin. Even some enterprises can not even pay interest on banks. So Joe satellite thinks that the difference of polyester staple fiber can not take this way in China. His polyester staple fiber has to go the characteristic route and make high value-added products if he wants to go. Only by such a way can we find a way to win the "Rome".

Profiled fibers and functionality Polyester staple fiber

According to our understanding, at present, the special-shaped fiber and functional polyester staple products of Wuhe (Jiangsu) Differential Fiber Co., Ltd. are very rich, among which functional polyester has antibacterial, antibacterial, deodorizing, anti ultraviolet, far-infrared, cool feeling, negative ions, bamboo charcoal, and flame retardant. The differentiated polyester products include six categories: modified polyester staple fiber, profiled fiber, functional polyester staple fiber, colored polyester staple fiber, differential gold combination, PPS fiber and so on.

Cationic polyester staple fibers can be divided into cationic dyeable fibers (CDP) - high temperature and high pressure cationic dyestuffs, cationic dyeable fibers (ECDP) - two types of cationic dyestuffs at atmospheric pressure, dyeable cationic dyes or disperse dyes.

Cationic dyeable high temperature and high pressure cationic fiber chromatography is complete, bright color, high color fastness, dyeable dark. The addition of flexible group and polar group during polymerization has good softness and moisture absorption. At present, most of this fiber is used for woven blended yarn.

Cationic easy to dye or easy to dye cationic fiber (ECDP) at atmospheric pressure. Due to its dyeing temperature similar to wool, and because of its soft handle, spinning various fancy yarns with ECDP fibers blended with wool or completely replacing wool in wool spinning industry has gradually become a trend. Due to the continuous improvement of printing and finishing technology, the high quality Western-style fabrics made of blended yarns with high proportion of ECDP fibers have been adjusted and processed, and their handle and drapability are closer to wool products. In the home textile industry, the manufacture of artificial fur is made of imported acrylic fibers and ECDP fibers, which can be blended with acrylic fibers in the same bath. It can completely replace acrylic fibers as raw materials for artificial fur.

Compared with conventional polyester, cationic modified polyester improves dyeing performance due to the weakening of regularity of molecular structure, and improves the pilling properties, moisture absorption and antistatic properties of polyester fibers. At present, cationic modified polyester fibers are widely used in textile products like silk and wool imitation. In addition, in recent years, the performance of the textile products has been greatly improved by the blending of cationic fibers with various fibers of different sizes, different lengths, different cross sections, different shrinkage fibers, and a variety of colored polyester fibers and other chemical fibers.

At present, cationic dyeable fibers have become the main products of Wuhe company. At the same time, they will also develop hollow staple fibers, normal temperature flat short fibers and normal temperature triangular fibers on the basis of cationic dyeability. This is a unique innovation in the domestic polyester industry.

In addition, it is worth mentioning that PSS fibers are resistant to high temperature and acid and alkali. fibre It has inherent flame retardant properties, extremely high thermal stability, excellent chemical stability, good radiation resistance and electrical insulation. Because of its superior performance, it has wide application scope and is especially suitable for bag type dust removal equipment in refuse incineration of coal-fired power plants. The main performance is its high temperature resistance, and the shrinkage rate is very small. It will not shrink under high temperature. The general temperature of the dust removal device of the power plant is very high. If the bag of dust removal becomes very small at high temperature, it will not achieve the proper dedusting effect. Therefore, this fiber is mainly used for dustproof in power plants.

To be practical and realistic, the polyester industry in China is facing the severe competition situation after globalization, speeding up the structural optimization and adjustment, changing the mode of growth, improving the capability of independent innovation and realizing the comprehensive upgrading of the industry, is the goal and main task of the new era. The modification of polyester fiber has always been a hot topic of concern for the industry. It is worth studying and drawing lessons from the practice of dealing with the crisis by using innovation to deal with challenges in Jiangsu.
