OCSiAl: Graphene nanotubes expand textiles’ functionality

  • ESD protection in harsh environments:
  • Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
  • Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
  • Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.

Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.

Filpucci @ PITTI Filati- The journey of responsible innovation continues

FILPUCCI GROUP proceeds along the path of commitment towards an ever more responsible innovation. The group takes part in the 83rd edition of Pitti Filati (June 27-29, 2018) with unique products, high-end knitwear and creative yarns, all resulting from the authentic Smart Innovation the company has been long committed to.
 
Research, style and fashion are key words for the world-renown Tuscan company, which unveils an always more responsible approach both at a corporate level and in terms of offer.
Here are some key elements to prove Filpucci’s relentless commitment:

Research, style and fashion are key words for the world-renown Tuscan company, which unveils an always more responsible approach both at a corporate level and in terms of offer.
Here are some key elements to prove Filpucci’s relentless commitment:

  • The GOTS (Global Organic Textile Standard) and OCS (Organic Content Standard) certifications obtained by the Filpucci dyeing plant add to the Clear to Wear (CTW) standard developed by Inditex Group and achieved in 2014 and to the Detox commitment, which was signed in February, 2016.
  • Not only the best raw materials, but also an established knowhow in the fields of dyeing and finishing, always under the key concept of Responsible Innovation. This concept extends to each and every FILPUCCI collection and their ever-increasing offer, the roughly twenty innovative new items, the Woolen line of carded yarns and the real spearhead of premium fashion, the Collection. Among this season’s new offer: Baby Camel Re.Verso™, RWS- certified merino organic wool, Re.Verso™ cashmere, organic silks and FSC-certified viscose.
  • The achievement of further certifications such as the FSC (Forest Stewardship Council) for viscose shows the care and respect towards the ecosystem as a whole, guaranteeing a product derived from a forest or a plantation forest in the respect of strict environmental, social and economic standards. The RWS (Responsible Wool Standard) finally guarantees the use of wool coming from livestock managed under rigorous criteria oriented towards the wellbeing of animals and the reduction of environmental impact.
  • Filpucci Group is all about a constant vocation towards new generation values and a reliable, traceable and transparent manufacturing process, as shown by the Re.Verso™ circular economy supply chain, of which the group is a unique ambassador in the field of high-end/low-impact knitwear yarns.

With absolute quality always in mind, FILPUCCI GROUP represents a corporate model that has made of sustainability a real mission, embarking on complex paths that have brought great results with fashionable textile solutions lead by ethnical and sustainable values. Thanks to this, Filpucci’s products have become part of Patagonia Collections, an important acknowledging from the brand’s part, whose managers stated: “We are always on the hunt for the highest performing, lowest impact materials. We were thrilled to find Re.Verso ™ (95/5 transformed) Cashmere yarn from Filpucci. It allowed us to create a range of products with the insulative and soft properties of cashmere while adhering to our mission statement; build the best product, cause no unnecessary harm.”
FILPUCCI GROUP’s commitment is evident and it moves forward thanks to the passion towards responsible and innovative paths that contribute to turning the group into a reliable partner, symbol of quality and excellence.

Filpucci is also a C.L.A.S.S. (Creativity Lifestyle And Sustainable Synergy) partner.
