Fabric testing still relies on tired eyes and special tools
A pick glass and a needle
Counting threads by hand takes minutes per direction, and two checkers rarely get the same number on the same fabric.
A cutter and a balance
Every GSM test needs a perfectly cut sample from a GSM cutter before it can even be weighed.
Slow lab routines
Twist and fibre-composition checks are manual and slow.
Kelwerk's tools do the looking for you, and they show their work: every thread they count and every outline they measure is drawn on the photo.
What you can measure today
Thread density (EPI / PPI)
Counts every warp end and weft pick in a woven fabric from one photo, including polyester satin, and marks each thread it counted.
Yarn count
Estimates or verifies cotton (Ne), linen (lea), worsted, metric (Nm), tex and denier counts from thread density and GSM.
GSM without a cutter
Measures the exact area of any cut piece from a photo. Add its weight from your balance and get the GSM, with far less dependence on a GSM cutter.
WeaveMetric Studio
An Android app that turns a phone into a fabric-testing station: thread density, yarn count and GSM from photos, with every result marked on the image.
Polyester satin, the fabric a pick glass can't handle
Dense filament yarns, a high sheen and long floats that hide the interlacings make satin and sateen the hardest fabrics to count by eye. WeaveMetric Studio has a dedicated satin method that reads the weave itself, then counts and marks every end and pick.
Three steps, then results in seconds
Calibrate once
Print our chessboard sheet and follow the guided steps. It's a one-time job per phone.
Photograph
Hold the phone over the fabric, ideally on a stand, and take the photo.
Read and review
Get the result with every counted thread marked. Adjust, recount a chosen area, or save it.
Results you can trust, from the phone in your pocket
Every result shows its work
Threads are marked and numbered, and GSM samples are outlined, so a supervisor can verify any number later.
Real-world scale from a phone
A one-time calibration with a printed sheet corrects your camera's lens distortion and lets the app work out how far away the fabric is. No special hardware.
Your results stay on your phone
Photos go to our servers only to be analysed and are then deleted. Analysed images and results are saved only on your phone, never on our servers.
