A new fabric locksticker machine can create a new strand of thread each stitch, a technique known as “ubt stitch machine” (USENIX: UBT).
Fabric stitch machines have been used for decades to stitch garments, but they’re becoming increasingly popular for more precise stitching.
Fabric stitch makers such as Tiaan van Heerden from the University of Groningen in the Netherlands have now used a new machine to produce a strand of fabric that can be pulled apart and twisted to produce an additional strand.
“A fabric can be made up of hundreds of strands and they’re often woven together, like yarn, and woven into the fabric,” said van Heersden, who was not involved in the research.
“When you try to pull a strand out of a fabric, it gets tangled and the whole thread will unravel.”
The new fabric-maker uses a two-stage process.
The first step involves folding the strand into two strips, with the first strip being made up by a single strand.
Then, it’s split into two more strips, each made up from a different strand.
The second stage is to separate each strip into its own piece of fabric, and stitch it together again, this time in a process known as twisting.
“This makes it possible to produce multiple strands,” said Van Heerdern, who also has a PhD in textile engineering.
“For a strand that’s not a single one, there’s no need to split it.”
Fabric stitch maker, Tiaant van Heertden, shows a fabric stitch machine at the New York Times Fashion Week in New York City, on June 12, 2017.
The new machine also uses the same technology as previous versions of the machine.
But the new device, which is a prototype, uses a much simpler technique that involves folding each strand in two strips.
This makes it much easier to make multiple strands.
“The new machine is also very small, so it’s easy to transport,” van Heercheden said.
The paper was published in the journal Nature Communications.
