New bio yarn shows
breakthrough possibilities

R

esearchers working at the University of
Bordeaux/INSERM have created yarns
of human cells from sheets of cellassembled extracellular matrix, or CAM. The
findings, reported in www.materialstoday.com,
are a significant achievement because the CAM
can be mass-produced for clinical applications
including tissue engineering. However, the
process is complex and the usefulness of
sheets for creating different shapes is limited.
"We make yarn by cutting the CAM sheet into
'ribbons' that can be used directly or twisted
into 'threads' [with] slightly different mechanical
properties," says Nicolas L'Heureux, University
of Bordeaux/INSERM, who led the research. The
yarns, which can be 2-10 mm wide and up to 3 m
long, can be used as they are as simple sutures
for wound repair or woven, knitted or braided
into almost any shape. Multiple yarns can be
twisted together to create thicker, stronger yarns
if different mechanical properties are needed.
The yarn can be simply dried, stored frozen and
rehydrated when needed, the researchers report.

ABOVE: Researchers have created
a bio yarn from human cells that
can be braided, knitted or woven
into medical devices or scaffolds,
which can be integrated into the
body without eliciting an immune
reaction. It has been used to
create a vascular graft, woven
on a circular loom.

Machine converts to knitting masks

K

arl Mayer, a global warp-knitting machine manufacturer
based in Obertshausen, Germany, says that its tricot machines
with two guide bars for elastic fabrics can be converted to the
production of tapes for masks. The company estimates enough
tape could be produced for up to 15 million masks per month
and that European machines could be put to work to augment
Asian production. It is also developing protective masks, as
well as instructions for their high-speed production. The masks
developed at Karl Mayer are manufactured in one piece, without
sewing. Photo: Karl Mayer.
