Prevent lint contamination

With global competition heating up, it’s in the U.S. cotton
producers’ best interest to produce the highest quality product. To do so, the
National Cotton Council (NCC) recommends a number of steps to be taken that can
assist in preserving cotton’s greatest attributes- its pure, natural quality.
Non-cotton impurities such as plastic, nylon, oil and grease can impair
producers’ relationships with textile manufacturers, undermine promotional activities
and threaten U.S. cotton’s excellent reputation, according to the NCC.

Contaminants can end up in finished yarn and fabric
products, resulting in defective fabrics and clothing seconds sold at a
fraction of their original value, according to an NCC and USDA press release.
Tainted products are costly to textile manufacturers and undermine consumer
appeal. Spinners carefully calculate which raw materials they can blend to
produce yarns and fabrics that satisfy their customers. There’s no room for contaminated
cotton lint in that mix, the NCC says.

Cotton producers are urged to use the following steps to
help keep the U.S. cotton product free from foreign material:


- Remove plastic irrigation pipes, irrigation ditch liners
and foreign materials from fields before harvest.
- Inspect, repair or discard worn or frayed module covers.
- Use cotton cord or rope, never use plastic twine for securing module tarps.
- Remove module covers and tie-down materials completely before ginning.


Insist on non-contaminating doffer and moistener pads -
never use black doffers.


- Follow picker manufacturer's recommendations.
- Service pickers daily. DO NOT OVER-LUBRICATE! Wipe excess grease from
fittings and housings.
- Clean picker heads and assemblies at least once a week to remove lubricant
build-up. Keep pickers and strippers in good mechanical repair.
- Use only water or picker manufacturer-approved wetting agents in the
moistening system.
- Never use motor or diesel oil in moistening systems.
- Replace worn machine parts, such as spindles, moistener pads, doffers,
bearings, bushings, springs and rails.
- Adjust spindle/doffer clearance to factory specifications.
