美國Ascend Performance Materials推出Acteev Protect™,這是一種創新技術,專門用於防止黴菌、真菌和其他微生物的生長,進而使紡織品和不織布(Nonwoven Fabric) 保持更長的使用時間。


活性鋅離子嵌入聚合物基體中,可產生不會被洗掉的持久溶液

Acteev Protect將鋅離子(Zinc Ion)技術與聚醯胺基(Polyamide)織物、不織布和針織布相結合,活性鋅離子嵌入聚合物(Polymer)基體中,提供不會被洗掉的持久溶液,這與局部整理或塗料不同。聚醯胺織物很耐用、柔軟,且為不織布過濾介質,可作為奈米纖維(Nanofiber)、熔噴(Melt-Blown)或紡黏(Spun-Bond)材料,可以有效地隔離有害顆粒。


以離子形式嵌入的鋅可以有效抑制細菌生長

Ascend表示,以離子形式嵌入的鋅可以有效抑制細菌生長。鋅是細菌生長所需的必需元素,因此細菌很容易使其進入細胞體內,但是鋅離子比其他必需元素(例如錳和鎂)更具競爭優勢,沒有這些礦物質,微生物就無法生長或繁殖。


新織物具有聚醯胺的所有優點

這種織物還具有優質聚醯胺的所有優點,在一次性口罩中,它們比聚丙烯(Polypropylene, PP)具更好的舒適性,並且可以對針織物和機織品進行染色、印花和洗滌。同樣地,這些特徵將維持服裝的壽命。由於在聚合過程中嵌入了鋅離子,使用Acteev Protect™製成的針織和機織製品可承受50次或更多次洗滌。

Patent-pending innovation includes textile fabrics and nonwovens to protect face masks, filtration and apparel Ascend Performance Materials has introduced Acteev Protect, a breakthrough technology specially formulated to guard against the growth of mildew, fungi and other microbes to keep textiles and nonwoven fabrics fresher for longer.
The technology is a leap forward in protection for face masks, apparel, upholstery, air filters and more, said Lu Zhang, Ph.
D.
, Ascend’s vice president leading the Acteev launch.
“Bacteria, mildew and other microbes growing on fabrics and filters cause the item to break down, discolor and give off unpleasant smells,” she said.
“Acteev Protect guards against that microbial growth, keeping the articles clean.
” The technology has been in development for several years, but with the recent shortage of articles resistant to microbial growth, Ascend accelerated the product launch by partnering with independent labs for testing and reallocating resources to scale up production.
“The current global scarcity of microbe-resistant materials is not going to end unless manufacturers are able to obtain the right media,” Dr.
Zhang said.
“We saw a way we could quickly meet those urgent needs with this innovative technology.
” Acteev Protect combines zinc ion technology with polyamide-based woven, nonwoven and knit fabrics.
The active zinc ions are embedded the polymer matrix, providing a long-lasting solution that does not wash away, unlike topical finishes or coatings.
The polyamide fabrics are durable yet soft to the skin, and the nonwoven filtration media – available as nanofibers, meltblown and spunbond – efficiently keep out unwanted particles.
The embedded zinc in its ionic form is a powerful inhibitor of bacterial growth, said Vikram Gopal, Ph.
D.
, Ascend’s senior vice president of technology.
“Zinc is an essential element needed for bacterial growth, so bacteria readily allows it inside the cell body.
But the zinc ion outcompetes other essential elements such as manganese and magnesium and chokes their ingestion channels,” he said.
“Without those minerals, the microbes can’t grow or reproduce.
” Other products use silver as an antimicrobial, Dr.
Gopal said, but that metal comes with unwanted environmental consequences.
“Silver is typically used as a finish or a coating,” he said.
“That process is water-intensive, and the excess silver has to be disposed of, eventually ending up in our waterways.
” Zinc, however, is labeled Generally Regarded as Safe by the U.
S.
Food and Drug Administration.
Additionally, the fabrics feature all the benefits of premium polyamides, which offer more comfort than polypropylene in single-use masks and allows knits and wovens to be dyed, printed on and laundered.
Polyamide 66 wovens and knits have considerable advantages over other types of nylons in garments and other textile applications, said Harrie Schoots, president-elect of the American Association of Textile Chemists and Colorists and a senior business leader of Ascend’s textile business.
“This material resists abrasion and doesn’t pill or shed microfibers.
It has a soft hand and excellent drape, and it can be dyed solid or bright colors,” Schoots said.
“Uniforms or activewear made with Acteev Protect will be durable and comfortable and can be designed to match current color trends.
” Additionally, these features will last the lifetime of the garment.
“Because the zinc ions are embedded during the polymerization process, knit and woven articles made with Acteev Protect stand up to 50 washes or more,” Schoots said.
Ascend is the world’s largest fully integrated producer of polyamide 66 resins and also manufactures fibers and chemicals.
Acteev Protect is the company’s first product offering available in ready-to-use fabric form factors.
The company plans to extend the line in the coming months to include polyamide 66 fabrics for medical applications and engineered plastics for high-touch surfaces.
