Storage and Handling

Fibercord&#;s nylon 66 yarns must be stored in unopened and undamaged original packaging  in an adequate warehouse under &#;normal&#; climatic conditions.  Extreme temperature and humidity levels or variations must be avoided. Normal climate conditions imply that, for any 30 days period, the following conditions are met:

• • The average temperature is between 10 and 35 °C The average of minimum daily temperature is > 5 °C The average of maximum daily temperature is < 45 °C The average relative humidity is between 25 and 80%The average of minimum daily humidity is > 10%The average of maximum daily humidity is < 90%.

Nylon 66 yarn&#;s shelf life is significantly long if the fibre is stored under normal climate conditions. Nylon 66 yarns must be protected from UV light and protected from noxious gases (nitrogen oxide maximum concentration < 0.25 ppm). We do not recommend the use of material-handling equipment with internal combustion engines in the warehouses where nylon 66 yarns are stored.

If the fibre is stored in unopened and undamaged original packaging and under climate conditions mentioned above, Fibercord defined the Nylon 66 yarn&#;s shelf life in 2 years from production data. Nylon 66 yarn&#;s shelf life can be extended by revalidating of yarn properties in our Laboratory.

sft are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

The yarn should be handled using the FIFO (first-in first-out) method. The package (pallet) must be opened at least 24 hours before being used; preferably, in the area where the product is going to be processed  and in an environment with a relative humidity of 60-80% to permit conditioning.

Dipped cord and fabrics  have limited storage shelf life. They  are sensitive to moisture,  ozone, heat and light and should always be stored in sealed black polyethylene film. We strongly recommend to verify the adhesion properties of the dipped cords and fabrics of older items before processing them.
