Polyolefin Film Identification in Combed Cotton Yarn Lots
Identify polyolefin film in combed cotton using FTIR spectroscopy and DSC melting peaks to enforce ISO 10306 claims before dyeing.
Optical Sorters
Sensor Separation
An automated industrial machine scans material streams to identify and separate items by color, shape, or chemical signature. In modern textile recycling mills, optical sorters identify blended fibers and non-textile attachments to separate them from pure cotton or polyester streams. High-speed sensors feed processing data to a computer to trigger mechanical separation.
Industrial Throughput
The processing capacity of automated scanning systems allows factories to handle metric tons of material every hour. When using optical sorters, the shredded textile waste is spread evenly across a fast-moving conveyor belt where multiple cameras capture real-time images. This rapid analysis ensures that the sorting speed matches the requirements of large-scale recycling plants.
Contaminant Extraction
Precise pneumatic air jets blast unwanted materials out of the falling stream of shredded fabric. Because optical sorters detect slight differences in light reflection, the air jets can target specific polymer fractions with high accuracy. This action isolates polyester from nylon or mixed fibers.
By separating these materials, mills obtain clean feedstock for subsequent chemical recycling.
Purity Level
The consistency of sorted outputs directly affects the strength of recycled yarns. Recyclers employ optical sorters to achieve the ninety-nine percent purity demanded by synthetic fiber extrusion plants. This processing prevents contamination from affecting the final spun yarn quality.
