1、CHINA CHEMICAL REPORTER September 21st, 2010 18WWW. CCR. COM. CN Fine and SpecialtyChina's Textile Auxiliary Industry Needs Technological InnovationNearly 100 categories and about 15 000varieties of textile auxiliar

2、ies are producedin the world today. Reportedly, their glo-bal annual sales volume is 2.8 million tons,with a sales value exceeding US$16 billion.Internationally, 100 kg of fiber consumes 7kg textile auxiliaries on averag

3、e, but in China,100 kg fiber consumes only 4 kg of textileauxiliaries. In recent years, as the EuropeanUnion (EU), the United States and Japanconstantly transfer their textile plants toSoutheast Asia, the demand for text

4、ile aux-iliaries in Southeast Asia has increasedrapidly, exceeding North America, WesternEurope and Japan and ranking first in theworld. However, the leading producers oftextile auxiliaries are still in Europe andJapan.

5、China's output of printed and dyedcloth has grown at an average annual rate ofmore than 10% in recent years, makingChina the world's largest producer today.With the development of China's textileindustry, the

6、 demand for textile auxiliariesgrows rapidly. In the future, China's textileauxiliary industry will have a huge devel-opment potential and a broad marketprospect.Textile auxiliaries are an important classof textile c

7、hemicals. With the cancellationof international textile and garment exportquotas, the international market is settingeven greater technical barriers and tradebarriers, especially green barriers, on tex-tiles and garments

8、 as well as on textile dyes.These green barriers lead to unprecedentedbans and restrictions on uses of textileauxiliaries. Among them, one of the twostrictest barriers is the new standard thatthe EU made in 2002, which b

9、ans and re-stricts the use of 17 categories of textileauxiliaries, and the other is the EU'sREACH regulation. These barriers will sig-nificantly increase the export costs ofChina-made textiles and textile chemicals,g

10、reatly enhance the innovation costs of newtextiles and textile chemicals, and dramati-cally restrict the development of China'stextiles and textile chemicals.Currently, the development of the world'stextile auxil

11、iary technology shows the fol-lowing four major trends. First, complextechnology is used to realize the multi-func-tionality and high functionality of textileauxiliaries. Second, suitable auxiliaries aredeveloped for new

12、 fibers. Third, high-techproducts are used to complement and evenreplace traditional textile auxiliaries accord-ing to market requirements. And fourth,environment-friendly additives are increas-ingly preferred.In recent

13、years, China's output of printedand dyed cloth is booming. China's textileauxiliary industry has the followingcharacteristics. First, it requires low fixedinvestment but produces a high added value,leading to a h

14、igh profit margin, so it attractsmany investors, and the competition amongtextile auxiliary producers is very intenseand chaotic. Second, it makes extensive useof complex technology, and the research ofthe formulation is

15、 very critical. Third, itfeatures small-batch and intermittentproduction, and production equipment isversatile. Fourth, it has high requirementson application research, technical servicesand logistics.However, due to his

16、torical conditions, thedevelopment of China's textile auxiliary in-dustry still has some limitations and manyproblems as follows.(1) China's textile auxiliary producers sel-dom publish the compositions of theirpr

17、oducts, and their products lack inherentcharacteristics data.Inherent characteristics data has not beencreated for around 3/4 of China's textileauxiliaries. Due to this lack of information,the impurities in the texti

18、le auxiliaries areunknown, and the toxicological indexes andecological toxicological indexes for them can-not be established. This can increase theregistration cost of China's textile auxilia-ries in accordance with

19、the requirements ofthe EU's REACH regulations and affect theproduct mix of China's textile auxiliaryproducers.(2) China's current textile auxiliary standardsare backwardAt present, the quality indexes of most

20、 do-mestic textile auxiliaries have regular andgeneral indexes only but lack characteris-tics indexes, and there are no detection tech-nologies and methods for their physicalindexes. China's textile auxiliary industr

21、y isvery backward in areas ranging from detec-tion method standards to product indexstandards.(3) China lacks serialized and high-per-formance textile auxiliaries, especiallyspecial textile auxiliariesBlended spinning pr

22、oducts of natural fibersand synthetic fibers with complementaryproperties are becoming more and morepopular. And blended products of severaltypes of fibers need high-quality and low-flow pre-treatment and dyeing, printin

23、g andfinishing processes and associated auxiliaries.China can hardly produce serialized and high-quality additives for this area.New dyeing and finishing technologiesapplicable to many new fabrics need newspecial additiv

24、es. But till now, this issuehas not yet been addressed in China. Forexample, the newly developed ultra-finefibers, hetero-denier fibers, hetero-shrink-age fibers, hetero-cross-section fibers,hetero-material fibers, elast

25、ic fibers, newcellulose fibers (such as Tencel, Modal,LyoceU, etc.), composite fibers and func-tional fibers need special auxiliaries. Forexample Tencel fiber and soybean proteinfiber need bath lubricants and enzymes int

26、heir production and processing.The number of textile auxiliary varietiesthat China has developed and produced ac-counts for only 8% of the world's totalnumber. The proportion of the special andhigh-grade textile auxi

27、liaries now in use thatChina can produce is even smaller, so suchchemicals have to be imported. For example,almost all the organic fluorine anti-oil agentsused in China are imported.(4) China's textile industry is re

28、lativelyCHINA CHEMICAL REPORTER September 21st, 2010 20WWW. CCR. COM. CN Fine and Specialtyproducers, the proportion of their productsthat are sold domestically has increased from67% in 2000 to 77% now. From the view of

29、clothing consumption, China's per capitaconsumption of textile products has grownfrom 7.5 kg in 2000 to about 16 kg in 2007,but this level is much lower than the percapita fiber consumption - 30 to 40 kg - ofdevelope

30、d countries. From the view ofhome textiles, with the increasing numberof new homes and the enhancement ofpeople's consumption level, the averagehousehold has a textile consumption of 10 -20 kg. At present, especially

31、 in rural China,textile and apparel consumption remainsvery low. All these indicate that China's do-mestic textile and clothing market still has ahuge development space and potential.China's domestic textile mark

32、et still hasmany new growth points. For example, in-ries in Asia is growing rapidly and is ex-pected to reach 1.36 million tons in 2011.At present, China's textile auxiliary outputonly accounts for about 10% of the g

33、lobaltotal. This is not commensurate with theshare, about 60%, that China's dyestuffoutput accounts for in the global dyestuffoutput. This year, as the world economyrecovers, Chinese companies will exportmore textile

34、 auxiliaries.China is the world's largest textile pro-ducer and processor. As textile auxiliariesdevelop further toward multiple functions,high performance and environmentalfriendliness, developing and producing fast

35、,efficient, environmentally friendly and en-ergy-efficient textile auxiliaries and print-ing and dyeing processes is an imperativeresponsibility of the textile auxiliaryindustry.dustrial textile products are widely used

36、ininfrastructural construction and health andmedical fields. Currently, the textile con-sumption in these fields only accounts for15% of China's total textile consumption.As China gradually strengthens itsinfrastruct

37、ural construction, it is expectedthat the industrial textile market will growfaster and has a broad market prospect. Atpresent, with the stabilization of domesticemployment, China's domestic demand canbe expected to

38、grow steadily. Experts pre-dict that by 2012, China's output of textileauxiliaries will reach 1.16 million tons, witha sales value of RMB23.29 billion.As the United States and Western Euro-pean countries gradually sh

39、ift their textileproduction to Southeast Asia, Asia has alsobegun to become the global center of textileauxiliaries. The demand for textile auxilia-China's Plastic Additives Industry Needs Independent Innovation and

40、Environmental ProtectionAs an important part of the specialty chemi-cals field, China's plastics additives indus-try has developed greatly in recent years,but certain reforms remain urgent.Heat stabilizersAt present,

41、 heat stabilizers have devel-oped into the second largest category ofplastic additives, just after plasticizers. In2009, China's total capacity to make heatstabilizers was about 480 000 t/a, contrib-uted by nearly 1

42、000 heat stabilizermanufacturers. They can basically produceall varieties of heat stabilizers needed bythe downstream industries. According tothe estimates of Chinese plastics industry,China's demand for heat stabili

43、zers willreach more than 300 000 tons this year.China's heat stabilizer sector still hasmany places to improve, for example, morevarieties. The world makes more than 1000 types of organic tin-based PVC heatstabilizer

44、s, but China can commerciallyproduce only 40 types. Meanwhile, highlytoxic, high-pollution and low-end lead saltstabilizers still absolutely dominate China'sheat stabilizer market, and the market shareof organic tin

45、products in the domestic mar-ket is far lower than in advanced countries.There are many small heat stabilizer pro-ducers in China. They often seriously pol-lute the environment. Their products con-tain a lot of impuritie

46、s and water but arevery cheap. So they have a serious impacton the production and marketing of high-quality heat stabilizers. As a result of in-sufficient investment in R & D, the pro-duction and application of new t

47、ypes ofheat stabilizers cannot satisfy the devel-opment needs of China's PVC industry.The majority of China's users of high-grade heat stabilizers still mainly rely onthe production and use of plastics. Tradi-tio

48、nal toxic heat stabilizers contain Cd, Pb,Sb or Ba and will be eliminated from themarket in the future, giving new develop-ment opportunities to environment-friendly organic tin-based, organic zinc-based and organic chem

49、icals-based heatstabilizers.It can be expected that organic heat sta-bilizers that are completely free of heavymetals will represent the development di-rection of PVC heat stabilizers. But thecomprehensive performance of

50、 existing or-ganic chemicals based heat stabilizer prod-ucts containing no metal is hardly compa-rable to that of organic tin-based and or-ganic zinc-based heat stabilizers. Thus, atimports.In recent years,many countries
