Pesky plastic: Mills don’t want it in their cotton
Plastic grocery bags, black agricultural mulch used widely in vegetable production, and other sources of plastic that make it through the ginning process and into the yarn for spinning mills have become an increasing concern, according to Tommy Valco, USDA Agricultural Research technology transfer coordinator at Stoneville, Miss.

But despite a general tendency to link the increase to the rapid and widespread adoption of the round module system, preliminary studies indicate very little of the plastic that makes it into spinning yarn, giving textile mills fits, is traced to the module covers, he says.
Rather, most of it comes from plastic grocery bags, black agricultural mulch used widely in vegetable production, and other sources.
