PRODUCT TESTING

Palmetto operates a state-of-the-art technology center in Chennai, India. The center is staffed by veteran textile, polymer, chemical and mechanical engineers experienced in all stages of FIBC production. They work under the direction of a Ph.D.-level polymer engineer.

The center’s staff:

  • Evaluates your current bags to see if they meet specifications
  • Provides a detailed analysis on all deviations and how they affect you and your customers
  • Offers suggestions to optimize your specifications and minimize costs
  • Creates a project folder of all new specifications to include CAD drawings in both metric and U.S. measurements

All testing is performed in a fully equipped laboratory that meets or exceeds the requirements for DOT-approved testing laboratories in the United States. Testing parameters include:

Raw Material Testing

As per ASTM-D 1238, using MFI tester the raw material is fed into the machine. At the specified temperature and test load, the material is extruded through a narrow orifice and the cuttings are taken for a specified time and the weights of the extrudates are noted.

MFI is calculated using the formula:

MFI (in grams/10 m) = Wt. of Extrudate (in grams) x Specified Time (in secs) / 600 m-secs

Denier Testing

Samples of 6 winded bobbins are taken every hour. 9 meters of tape from each bobbin are taken separately and weighed. The average of that weight is the denier of the tape.

Tensile Strength

Collect 1 meter of tape from the sample, affix in the KMI machine jaws (distance between the jaws should be 20 cm) and operate the machine to find out the strength, GPD, and elongation.

Liner

The supervisors check width, thickness, and cut length of the liner every hour.

Width of the Fabric

The width and weave quality of the fabric and webbing is checked every hour by the weaving operator and crosschecked by the supervisors.
