The Nonwovens Institute Analytical Labs offer services to industrial clients in the areas of standard method testing, test method development, and instrument development.
The Nonwovens Institute also offers consulting services to the nonwovens and affiliated industries.
Fee Structure for Services
These services are offered under confidentiality.
The costs are determined on the basis of the equipment usage;each equipment has a specific facility use rate.
Cost estimates will be provided upon request within 24 hours.
For standard tests and routine pilot trial, a simple Testing Services Agreement (TSA) is required.
For more involved, open-ended projects that may result in the generation of intellectual property, a Memorandum of Agreement (MoA) is required.
If you have any questions, please contact us by telephone 919-515-6551 or for a quotation, email us at nonwovens@ncsu.edu
Physical and Mechanical Testing Laboratory

In addition to these standard equipment, we offer customized solutions for dealing with new and nonstandard test methods. The following are examples of tests routinely performed in our laboratory
- Absorption, desorption and in-plane liquid transport
- Screw driven and servo hydraulic Instrons for performing a variety of tests including tensile, tear, dynamic friction, creep and fatigue.
- Favimat for testing single fibers
- Mocon for testing moisture vapor transmission.
- Abrasion Resistance
- Bursting strength
- Thermal properties including thermal absorptivity, diffusivity and resistivity
- Thickness
- Bending stiffness
- Dynamic tensile imaging
- Hydrostatic head for measuring barrier properties
- Fiber creep rupture
- Basis weight
- Air permeability
- Custom test method development
Polymer Analysis Laboratory The Nonwovens Institute polymer laboratory offers the houses the following analytical equipment for the measurement of critical polymer properties
- Device for the measurement of intrinsic viscosity
- Haake MiniMelter for the measurement of viscosity as a function of temperature and time. This unit device measures the pressure drops in a small extruder while recirculating the polymer
- Differential Scanning Calorimetry - DSC for the measurement of thermal properties of polymers
- Arizona instrument for the measurement of polymer chip moisture content.
- Fast Fourier Transform Infrared - FTIR for the examination of surface chemistry
- Haake Meltflow index analyzer
- Fiber orientation distribution, the key property governing the performance of nonwovens, is easily measured using nondestructive optical techniques developed and patented by The Nonwovens Institute
- Digital Volumetric Imaging of samples allows us to create a 3D images of the structure layer by layer. This information can be used to further characterize and document properties such as hydro-entanglement efficiency and particle dispersions in filter media. This technology was developed by Resolution Sciences Corporation, a NCRC member company
- Texture Analysis allows for quantitative analysis of surface texture with respect to texture periodicity and amplitude. Jet streaks in hydroentangled fabrics can be easily quantified
- Surface profiling measures changes in the z directional topography of materials, using laser interferometry
- Correct contact angle can be measured using our special optics and illumination system
-
Pilling and Fuzz can be quantitatively
measured using our turnkey imaging solution
- Simulation and measurement ofS the properties of waterjets.
- Simulation of cavitation
- Fiber dispersion in wetlay and mixing tanks with different baffle-impeller configurations and turbulent intensity field measurement for various baffles
