3、不确 定，它们在无纺布的整体销售继续维持强大。“Weare in a lot of very unique, niche applications, particularly withTyvek, says Tom Powell, president of DuPont Protection Technologies.“The combination of brathability and protection that Tyvek provides has given us advantages inmany applications, such as protective apparel

4、and in medical packaging. “我们拥有许多独特，小众应用，特别是高密度聚乙烯合成纸，杜邦防护技术主席Tom Powell说道，“高密度聚乙烯合成纸赋予的透气 防护性能带我们许多应用里的优势，如防护服和医疗包材。Tyvek, DuPont fsashspun nonwovens technology, serves a number of core markets, including graphics,construction and envelopes, in addition to protective apparel and medical packaging.

5、DuPont sother nonwovertechnologies include Sontara spunlace nonwovens, which target specialtywipes and medical apparel applications, and Energain, a nanofiber-based product targeted initiallytoward specialty battery and high-end filtration applications.Most of DuPont s nonwovens business falls under

6、 its DuPont Protection Technologies (DPT) business,which was formed three years ago by combining the nonwovens business (consisting of Tyvek and Sontara)with its sister units, including Kevlar and Nomex, on the aramid fibers side of the business. Thisdivision was formed to group technologies and pro

7、ducts that protect people, the environment andcritical processes worldwide. This marriage was part of a larger, company-wide streamlining thatbrought the number of DuPont business units from 25 to 14 and allows the company to respond to customertrends better while capitalizing on synergies that exis

8、t between the business units.杜邦非织造布的许多业务都归于DPT(杜邦防护技术)，“We continue to look for places where we can leverage our technologies to bring new products whilekeeping costs down to be competitive, Powell explains. This has helped protect DuPont againsteconomic volatility and uncertainty as well as rising

9、raw material costs.An important market for Tyvek, construction, falls outside the scope of DPT but reports indicatedemand continues to be strong despite difficulties in this market, which is tied heavily to housingstarts. Other markets for the technology include envelopes, which have beenchallenged

10、by a slowdown in snail mail, and other packaging applications,where Tyvek can offer great breathability and a good green story with its recyclability. In a nutshell,despite concerns in construction, Tyvek growth has been strong enough to convince DuPont to bringa production line in Luxembourg back o

11、n-stream. The line, which has been mothballed for several years,will help support the company s existing garment andconstruction business, according to Powell.“ Tyvek is a unique technology, he says. There is no other producer o flashspun polyethylene.It delivers a unique combination of breathabilit

12、y and protection. The company is always looking for new applications, he adds. We are currently working on a coupleof things that could be big but are still in the early stages. He went on to say that electronicshave been a recent focus where the reflective properties of Tyvek provide a unique value

13、 in lightingapplications.杜邦公司总是寻求新的应用领域，他补充到，“Other advancementsin Tyvek include adding metallization and other finishing techniques to provideenhanced protection without sacrificing breathability. One such product provides a silvery finishto enhance designs in banners, bags, tags and other decorati

14、ve design applications.高密度乙烯合成纸的其他优势包括添加金属镀化和其他后整理技术 来在不牺牲透气性的条件下增加防护性。比方一种产品提供银色后整理，在横幅，袋子，标签和其他装饰品设计里来提升设计。Moving toward Sontara, DuPont spunlace business, this technology continues to be strong in medicalgarments, where it offers low cost, sophisticated products to keep workers safe and comfortab

15、le.Two years ago, DuPont chose to forego its Advanced Composite Technology (ACT), which it used to makeSuprel garments for medical workers. However, Powell says this market remains important to the company.It is a vecompetitive market space but it is still a solid application for us. We have some la

16、rge-scale, highquality brands with nice competitive technologies. Additional markets for Sontara, which is a pulp-based spunlace technology, include high performancewipes products for car detailing, printing and aerospace applications and other areas where innovationis valued. Although they have don

17、e some business in consumer wipes markets over the years, DuPontpresently does not focus on that business area.DuPont s latest nonwove-based business, Energain brand, continues to ramp up at a small commercialfacility in Chesterfield, VA. This technology is a variation of a former technology, purcha

18、sed severalyears ago from a Korean firm and marketed as HMT (hybrid membrane technology).According to Powell, the current Virginia line is a small commercial scale and sampling line thatis able to show potential customers exactly what the nanofiber-based material can achieve.We call the line a produ

19、ctionpilot and we are doing what we intended, that is demonstrating the base technology, developing basicdata for a full-scale commercial facility and producing innovative samples for customers. Energain will mainly target the battery separator market where it can provide increased power,improved ba

20、ttery life and also offer higher stability at increased temperatures. Beyond lithium-ionbatteries, Energain has prospects in batteries in specialty consumer applications, including laptops,cellphones and power tools.In other new market developments, filtration continues to be an area of interest for

21、 DuPont. Thecompany has provided Nomex for many years into hot-gas filtration applications. About two years ago,the DuPontportfolio was expanded with Nomex KD, a medium that combinesNomex and Kevlar fibers in a unique nonwoven filter medium. The product is well suited for hightemperature applications such as asphalt production and cement clinker
