Foreign fiber contamination
Find polypropylene, coloured, and foreign fibers in the web before they reach the dyehouse.
Example outputs shown for illustration. Numbers depend on your samples and protocol.
What you get
The measurement, today
A stray polypropylene thread survives opening, carding, and weaving unseen. It refuses dye, then surfaces as a white streak in a finished piece. Hand inspection of a web catches the obvious ones and misses the short, pale ones.
What it costs
Contamination is usually found after dyeing, when the fabric already carries its full cost. Recycled and blended feedstock raise the odds every season, and a single contaminated lot can push a roll to seconds or scrap.
From image to reviewed result
- 1
Image the web
Capture the card web, sliver, or bale surface under controlled, even illumination.
- 2
Separate the odd fiber out
Segmentation flags fibers whose colour or reflectance departs from the base web, down to sub-millimetre fragments.
- 3
Measure and classify
Each contaminant gets a length, width, and colour class, so pale polypropylene is separated from dark trash.
- 4
Map and rate
Contaminants are mapped to their position and totalled into a contamination rate per kilogram.
Scope: Detects and locates foreign fibers visible at the imaged surface. It does not identify polymer chemistry; confirm suspect fibers by FTIR or a melt test before rejecting a bale.
