Since entering the 21st century, our country's nonwovens technology achieved great progress, rising consumer demand, nonwovens equipment manufacturing, raw material production and products processing formed a full range of supply chain system, including medical non-woven fabric production and application development is particularly prominent.
Non-woven fabric can be further processed into artificial skin, prevent adhesive gauze, surgical clothes, cover the substance of resistance, XiaoDuBao cloth, protective clothing, masks, antibacterial cloth, diapers, sanitary napkins, sanitary pads and civil cloth, wiping cloth, wet towel, towel, soft towel roll, beauty products, etc. Mainly adopts spun-bonded, hot melt compound and water three process, PP spun viscose cloth production health cloth, sanitary napkin and sanitary pads, hot melt composite fabric spunlace cloth is strictly controlled operation for personal care and environmental protection products. Latest spinning into network combined with melt-blown superfine melt-blown fiber diameter (2 ц) and FM fine denier fiber (0.5-0.8 Den fineness) made of SMS/SMMS non-woven material, uniform product quality of a material soft, good tensile strength and liquid barrier, the advantages of hydrophilic, waterproof, anti-static, anti-aging, dedicated to PP spun-bonded and SMS, spunlace nonwoven (viscose and polyester blend fabric) and the elasticity of medical acupuncture non-woven fabrics and other health care products processing.
Global non-woven production 4.5 million tons in 2004, 05 maintain a 7.5% growth rate, 09 is expected to 6.4 million tonnes. Due to the sanitary napkin surface material is lightweight, same weight increase of the total area of the coil. Domestic non-woven production 830000 tons in 2004, four years grew by an average of 18%, in 2009 total close to the United States, and Europe. Disposable medical non-woven fabric, sanitary towels, diapers and care product demand is growing, small nonwoven coil exports, 50% products export. Non-woven fabrics imported into negative growth after 2003, exports to 16% growth.
Spunlace method, spun-bonded method is of the fastest growing domestic non-woven technology in recent years, followed by acupuncture and thermal bonding. In the early 1990 s, Taiwan hao company built the first domestic spunlaced nonwoven production line in hangzhou, 2004 domestic 30 spunlace non-woven fabric production line has been installed. Our self-developed moderate price of PE/PP sheath-core composite staple fiber is used for processing health materials with hot-rolled non-woven, suzhou wei and Shanghai tenglong import equipment of Europe, in the domestic dozens of hot rolling the fabric production line is in the leading level.
Making health care product with 100% fabric hot non-woven PE/PP composite staple fiber, its high polymer material and surface treatment agent is higher than hot-rolled non-woven requirements.
Medical nonwoven is diagnosis and treatment of necessities, similar medical protective clothing, infection control products, incontinence supplies, surgical gauze and ward equipment during "SARS" in 2003 to become a hot commodity. On December 9, 2002, non-woven industry developed independently developed in guangdong province with a disposable medical protective clothing won the provincial drug administration approval, become a handful of domestic peers at the time, but the protective clothing fabrics are still dependent on imports, cannot independent production bring SARS prevention and control work in China at that time the difficult material. In the first half of 2003, only domestic nonwoven spunlace and spinning capacity growth rate of more than 40%. SARS unprecedented promoted the development of various medical gowns, masks, protective equipment, string melt-blown nonwovens and spun-bonded, melt-blown SMS composite nonwovens, SMMS gowns and masks, spun-bonded nonwoven fabric and TPU moisture permeable membrane, and various kinds of microporous breathable membrane composite products. SARS, medical non-woven total amount 13% increase from the previous year.
Non-woven bag industry is one of the traditional pillar industry of China, along with economic development, non-woven bags industry gradually from the glory dull.
According to industry life cycle theory, it is a mature stage of transition into the sunset, the number of firms becomes saturated, the industry tends to excess production capacity, marginal revenue decline in price competition within the industry has become the basis of competition, technology mature. Due to large number of enterprises in the industry, tends to excess capacity, supply and demand balance in the market or the state of oversupply, fierce competition among enterprises. This level of competition intensifies, on the one hand makes large-scale production and cost reduction has become an important means of business competition, it also enables companies in product performance and product differentiation and work hard, to innovate. Creative industries as a vibrant new industries, rapid growth in recent years. Currently the world's creative industries to create daily output of up to $ 22 billion, and growing at a rate of about 5% of the increase, expected in 2011, the total size of the global creative industry will exceed 100, $ 00 billion.
In some developed countries, the creative industries, growing faster, such as the United States reached 14%, the UK 12%. Creative industry has developed into a huge industry and economic background "sunrise industry in the 21st century." Creative industries and economic ties woven bags, woven bags on the development of its industry has played a huge role in promoting. At present, non-woven bags industry in general and there is some hidden unemployment, low value-added industrial products, the unit energy consumption, lack of effective demand. The creative industry is the economic development of these symptoms resolve bottlenecks encountered a panacea.
We can go to find through the development of creative industries, non-woven bags that can drive economic development, and through policy support and investment to accelerate the development of industry, non-woven bags, and the integration of their economies and traditional textile infrastructure projects, in order to achieve the promotion of two-way common development purposes.
(A) the diffusion effect of 11 creative industries and creative industries concept of creative industries, creative economy is a development in the context of globalization, consumer society together, respected innovation, individual creativity, emphasizing the cultural and artistic support and promote the economy The emerging concept of economic thought and practice. Back in 1986, the famous economist Romer (P1 Ro2 mer) had written that new ideas will rise to endless new opportunities for new products, new markets and wealth creation, so new ideas to promote a country's economy is growing The driving force. But as a national industrial policy and the strategic concept of creative industries is clearly the author of a special working group UK creative industries. May 1997, British Prime Minister Tony Blair for the revitalization of the British economy, propose and promote the establishment of a special working group creative industries. The team in 1998 and 2001 respectively, issued two research reports, analysis of the status quo and make the UK creative industry development strategy; in 1998, the Task Force for the first time the UK's creative industries and creative industries are defined, the creative industries defined as "source Since individual creativity, skill and talent, through the development and use of intellectual property, with the creation of wealth and employment potential of the industry. " According to this definition, the British advertising, building 67 Central University of Finance in 2010 on four buildings, arts and heritage transaction, Crafts design, fashion design, film, interactive leisure software, music, performing arts, publishing, software, television, radio, etc. industry recognized as the creative industries.
(B) the impact of creative industries on the production function we are familiar with the traditional production function is Cobb by mathematician and economist Douglas in the early 1930s jointly proposed. The general form of the function is Q = ALαKβ, wherein, Q is output; L and K are labor and capital inputs; A, α and β for the three parameters, 0 <1. When α + β> 1 for increasing returns to scale; if α + β = 1 when constant returns to scale; and when α + β <1 for decreasing returns to scale. Is generally thought that the practical production function α + β = 1, where α is approximately 1/4, β is about 3/4. If we let β = 1 -α, into the above equation can get Q = ALαK1 -α, then get the M PL = A (1 -α) L-αKα. Because A (1 -α) Kα is a constant, and because α <1, so the function will be a diminishing curve MPL, that marginal returns to labor factor is diminishing. But with the level of economic development of an economy growing defect CD production function gradually appear, since the 1950s, made in Kuznets, Solomon, Kendrick et al postwar US economic growth The research work, they discovered a common problem: the US national output growing faster than the land, when people, material and other renewable growth capital. At the same time, Kuznets in the study of capital formation in the United States found that: relative to national income growth, the US net capital formation is decreasing, which means more output from less "capital" produced, this phenomenon is called "Kuznets mystery." In fact, in the CD-type production function, input elements technology portfolio is actually fully reflected in A, that is implicit assumption of constant technology in the function. Of course, economic conditions in the traditional knowledge and technology updates slower, economic growth came mainly from capital and labor inputs, and the knowledge and technical elements naturally is considered the same "fixed value", and in general In the traditional production function A regarded as constant around 1101. However, with the last century, the 1980s, gradually mature space technology and popularity of electronic information and network technology, people gradually found that the gap between the traditional CD production function and the real value of the total drawn between showing growing trend, the reason is very obvious that the traditional function of knowledge technical coefficients A "static" hypothesis can not adapt to rapid technological updates and product life cycles are significantly reduced in the modern economy. So we have to introduce a production function: Q = Aθf (K, L) = AθKαLβ, where θ, α, β> 0, so that we can find 时 when θ = 1, Q = ALαKβ precisely CD production function, it We only introduce new production function as a special case. Here we let θ> 1, A is the independent variable. K and L treated as constants, if we suppose that f (K, L) = μ, then the production function can be simplified as Q = μAθ, but this time M PA = μθAθ- 1, due to θ> 1, θ- 1 > 0, so the MPA is an increasing function of the curve. Here it is necessary to explain that we are talking about the argument refers A broad knowledge and technology, it is not only human nature has gradually acquired by exploring the natural sciences and high technology, are also included such as enterprise resource management of social sciences, and "creative" is the core of the A's, especially differentiated product demand intensified even more so today. Figure 1 Knowledge Economy new production function Source: Li Yufeng, "Knowledge Economy", Nankai University Press.
Second, the impact on the economic development of non-woven bags creative industry research if regarded as a classic CD-type production function to the new knowledge-based economy shift from the traditional economic production function to scientific and technological innovation as well as more high-end creative economic transformation, then This is undoubtedly a higher level of economic take-off again. Non-woven bag economy still dominated capital K and labor L, measure the knowledge and skills of A also unable to form a leading role on the GDP. In other words, the current non-woven bags economic development of creative industries must be in capital and labor as the core elements of traditional industries combined only meet the development requirements of the current industry structure.
(A) non-woven bags economic situation industrial development lifecycle (Industry L ife Cycle) theory is the concept of biological life cycle to reflect the industrial production, development, theory change process. An industry life cycle refers to the decline of the industry from the primary process, including germination, growth, maturity and decline of four stages and at different stages in the number of 68 companies out of the first four 2010 Central University of Finance the amount of production scale , technical maturity, market maturity exhibit different characteristics. According to industry life cycle theory, at this stage it is in the transition from maturity to decline. Currently, the adjustment of industrial structure, the return of free trade, and many other factors make non-woven bag products industry is facing opportunities and challenges, woven bags products industry showed the following status quo: 11 export growth has declined markedly. Years 2006 to 2008 in October China non-woven bags and garment export growth has declined markedly. 2006 was 25,108%, 2007 is 18,177 percent in 2008, before declining to 5189% in October. 2009 January to July, China Non-woven bags and clothing exports to total $ 89.2 billion, down 1113%, a decline compared with the first half expanded 013 percent. Another non-woven bags of clothing from the United States Office (OTEXA) released the latest data show that, in 2009 1--7 month decline in US non-woven bags of clothing imports from China continued to slow down, the share of imports from China to 3814%, remained stable, but the changes in amplitude of products in each category are quite different, non-woven bags and garment export slowdown has brought about a great impact on employment and business sectors. 21 Non-woven bag proportion of domestic product increased year by year. 2003--2008 domestic sales proportion of China's non-woven bag products increased year by year, the total amount of non-woven bags wholesale and retail products are steadily. 2002, Chinese non-woven bag about 66% the proportion of domestic product, in 2003 and 2002 basically unchanged from the beginning of 2004, the proportion of domestic expanding domestic market share in 2008 up to 78% in 2009, 1--5 months, China's exports volume fell 11%, while domestic sales rose 15 percent. In recent years, increasing year by year the proportion of non-woven bags domestic product also shows that exports of non-woven bags and more difficult, so that a large number of export-oriented enterprises are turning to domestic-based, but also reflects our non-woven bags competitive products in the domestic market increased. 31 losses and a large number of enterprises are facing bankruptcy. The most direct impact of the financial crisis on China's real economy is undoubtedly the export processing enterprises, the impact on the apparel industry is particularly serious in recent years, Chinese woven bags industry affected by the international, domestic factors, the survival and development has been severe test. Especially in 2008, many domestic enterprises have limited non-woven bags into the car off, shutdown, the plight of the closure, a large number of non-woven bags basic living of workers lost their protection. Non-woven bag industry has reached "10 years of the most difficult," the mark. Such as: 2008 January-February 7792 in Zhejiang Province, woven bags enterprises, there are 2368 loss occurs; in April 2008, Shandong Cherry Group due to insolvency, was acquired by Ideal Group; June 2008, Zhengzhou National Cotton due to funding strand breaks, had to sell to survive; September 2008, Zhengzhou three state-owned enterprises due to operational difficulties woven bags and overall transfer.
Developed countries are the main markets in the world of disposable medical devices, in addition, some of the prior neglected countries and regions have gradually become a new market of disposable medical devices, including West Africa and Southeast Asian countries.
Over the past 10 years, the global disposable medical device industry to get an unprecedented rapid development. According to the latest foreign reports, in 2009 the total global sales of disposable medical device market reached $ 89 billion. In developed countries and regions United States, Europe and other disposable medical equipment sales accounted for about 45% of its total sales in the medical device market. By 2011, the global disposable medical device market is expected to reach nearly one hundred billion US dollars.
The United States is the world's largest disposable medical device market, with sales accounting for more than 40% global market share. Europe was the world's second-largest disposable medical device market, the market size of about 29% of the global market. Countries, including Japan, China, India and other Asian newly industrialized countries, including disposable medical equipment sales total about 17% to 18% of the international market.
Among them, inexpensive to produce polymer PP nonwovens price, can withstand ultraviolet sterilization or disinfection epoxy amine and other common means of disinfection, very suitable for the production of medical textiles, sanitary materials, bandages and other products to instead of cotton fabric products.
Using non-woven fabric made of medical textiles or sanitary material is more environmentally friendly because they can be used in the future as a waste of plastic raw materials, re-melted regeneration and recycling. Sanitary material can produce cotton, non-woven fabric can be produced most of their similar products, such as surgical mat, disinfection packaging, protect the wound material, foot care materials, sanitary masks, hospital bed sheets, drop cloths required for fleece, Doctor and patient gowns outer wear clothing and so on.
It is understood that, in recent years, only the United States, Canada and China annually consumes about 3.3 billion square meters of nonwoven materials for processing a variety of health materials and medical textiles. US annual disposable nonwoven cloth sanitary materials and medical textiles total sales at $ 3.4 billion total, ranking first in the world; the second largest in Europe, with a total sales of approximately $ 2.3 billion; Japan, China, India and other Asian emerging disposable nonwoven hygiene materials and medical textiles quantity consumed in industrial countries is growing rapidly. Parties forecast to 2011 global disposable nonwoven hygiene materials and medical textiles market sales will exceed 50 billion dollars.
Because non-woven cloth disposable hygiene materials and medical textiles can save valuable raw cotton fiber, plus the non-woven fabric of cotton fiber price is only 1/4, so more and more sanitary materials and medical textiles are the switch nonwoven disposable products, to reduce production costs. American Association for Medical Devices Industry executives believe that the next few years, the annual growth rate of international markets disposable nonwoven cloth surgical materials and sanitary materials will reach about 15%, it was succeeded disposable syringes, becoming another international markets best-selling disposable equipment products.
"Our country is a big country textile, and textile small country." On the "fiber and textile structural materials applications in the medical field" technology forum held recently, president of the China Textiles Industry Association, Li Ling Shen made the above statements. Textile big country we have a lot of performance in the clothing, textile exports, but in the field of industrial textiles are limitations. More than 80 percent of China's annual high-tech medical textile materials dependent on imports, the amount of more than 6 billion US dollars.
Chinese Academy of Engineering, China biomaterials committee chairman Zhang Xingdong said that at present, the United States, Europe, Canada, Japan and Australia 90% share of the global sales market, while domestic companies generally give foreign companies OEM, it is difficult to form the core competitiveness, it difficulties in the market share.
Li Ling Shen believes that the status quo must change medical textile industry has long been neglected, we can assure artificial skin and other textile materials, biomedical breakthroughs direction from masks, gowns and other disposable medical supplies, and gradually reduce the proportion of imports.
Surgical implants and in vitro filtration textiles most dependent on imports of textiles, product development focuses on the development of special biomedical fibers, forming technology and product development, the formation of significant results with independent intellectual property rights.
Medical protection, health care, hygiene textiles and non-implantable surgical textiles, wide range of large, has been basically achieved domestically and exported, product development focuses on special-purpose functionality and differentiated product development, improve product performance levels.
Future medical protective textiles will pay more attention to the development of anti-leakage technology materials, odor adsorption technology, anti-bacterial, anti-blood infiltration, antistatic, comfort and other functions.
Aspects of biomedical materials, will continue to strengthen the foundation for future technology research, combined with in-depth study of different races, human, organizational, natural composition of organ structure and function, macro and micro-bionic design and manufacture of various types of organs and blood alternatives to be studied. Biomaterials for tissue engineering in the field of bio-medical, and textile industries closely related to product technology, including fiber in the form of biomedical materials, and the use of scaffolds made of textile technology, the future will be greatly developed. Artificial kidney, artificial liver and artificial lungs, soft tissue substitute materials and interstitial tissue and heart valves and other biomedical materials is the focus of research products.
High-grade medical protective textiles, the overall development of products to enhance the uniformity and stability of medical protective materials, continue to reduce costs, will be the development trend of such materials. SMS nonwoven composite material will be the focus of development, to ensure a high strength spunbond layer wear resistance, intermediate meltblown layer improves the efficiency of filtration products, barrier properties, resistance to particle penetration, anti-static pressure, barrier properties and appearance even resistance, in order to achieve a good filtration, liquid-resistant and opacity.
The new aspects of medical dressings, material efficiency, high-performance products, high efficiency of care on behalf of the new medical dressings overall direction of development. Future products will be more emphasis on biological activity and intelligence. The development of new types of medical dressings may include antimicrobial silver dressings, dressings and other bioactive products require plasticity, good adhesion, good breathable, antibacterial and promote healing and hemostasis, analgesic function. In addition, it also has to promote division and growth of extracellular matrix effect epithelial cells, fibroblasts and endothelial cells, and other cells, effectively absorbing wound exudate, a barrier may be formed after drying the invasion of foreign bacteria physical barrier, as epithelial growth create a good environment. Downstream applications, including wound dressings, hemostatic sponge, medical cotton, medical gauze, gauze bandages, elastic bandages, plaster bandages, wound paste.
New types of health materials, the greater use of bio-degradable, antibacterial, super-absorbent type of raw materials and other functional fibers, thereby enhancing the disposable baby and geriatric diapers, sanitary napkins, wipes and industrial wipes functions such as product technology performance. In disposable sanitary materials, focusing on the development of materials and surface layer material diversion, research and development of biodegradable materials performance, increase flexibility and functionality of the surface layer of the material, as well as diversion fluffy layer and composite, can enhance sustained performance differential diversion.
