Lasers enable graphene-on-kevlar textiles for smart protective clothing

Researchers at Tsinghua University have used lasers to make graphene on Kevlar textiles, creating protective clothing that can record the wearer’s electrocardiogram (ECG) or sense a toxic gas.

Yingying Zhang and colleagues at Tsinghua University used a carbon dioxide laser to write on Kevlar, a synthetic polyamide fiber generally used to make body armor and personal protective clothing. The laser burned and depolymerized the Kevlar fibers and the carbon atoms recombined to form graphene, as shown by Raman spectroscopy. Using a motorized setup for the laser, they were able to scribe any design on the textile in minutes.

Haydale and Welsh Centre for Printing and Coatings secure English Institute for Sport contract

Haydale has announced that it will now collaborate with the English Institute for Sport (EIS) and the Welsh Centre for Printing and Coating (WCPC) to deliver a range of advanced wearable technology sport apparel for elite athletes.

Haydale has reported that initial prototype testing has been completed in live performance sessions with elite athletes with very successful results for wearability through its unique coating systems. Alongside supply chain partners, a range of garments are being manufactured in higher quantities for further use in elite sport settings, focusing on efforts to develop flexible and miniaturized electronics. This enhances product feel as well as reducing weight, allowing for optimized athlete performance.

Thomas Swan and GEIC develop graphene fibre

Thomas SwanThomas Swan logo recently announced that the Graphene Engineering Innovation Centre (GEIC) in Manchester has produced a fibre using Polyamide 6 and 0.2% loading of Thomas Swan Graphene Nanoplatelets (GNP’s).

GEIC successfully extruded and subsequently spun 1.5km of the fibre with 0.39mm diameter. This was said to bode well for continuing Thomas Swan's development of graphene in nanocomposites. Typical applications for this type of monofibre include carbon brushes for motors, seat belts or fishing lines.

Directa Plus receives grant to develop G+ graphene printing technology

Directa Plus has announced that it has received a grant for a project to develop an environmentally sustainable technology to digitally print its G+ graphene product on fabrics.

The GREEN.TEX project partners are Directa Plus, EFI Reggiani, the Italian subsidiary of global digital printing group Electronics For Imaging, Inc. (EFI), and IBS Consulting Group. The project will last for an initial period of 24 months and has a total value of around €1 million, of which Directa Plus will invest €240,000 and receive a grant of €100,000.

Versarien enters commercial partnership with textiles company MAS Innovation

Advanced materials company Versarien recently shared that it has signed a commercial partnership agreement with textile-sector company MAS Innovation. The agreement followed a letter of intent between the parties, which set out their intent to enter into a formal commercial partnership.

The agreement specifies the terms under which the parties would secure commercial orders for garments developed using Versarien's proprietary graphene ink materials. It allowed both parties to finalize additional contractual terms with third party brands.
