The microscopic world yields its secrets under the observation of the Microscopy Lab. A critical contributor to our understanding of materials and the possibilities they offer, the Lab utilizes optical, electron, and scanning probe microscopy to examine and analyze the wide range of materials investigated by Milliken Research.

Light Microscopy (LM)
Examination of materials, fiber identification, cross sections — for shape, size, presence of texturing, dye penetration, blend distributions — and also for particle contamination or sizing, and measurement for spacing differences (i.e., defects).

Scanning Electron Microscope (SEM)
Examination of the surface features or cross sections of any appropriate specimen. Typical samples include fabrics, yarns and their coatings and treatments, non-woven products, fiber structures or modifications or damage, defect analysis, particles size, dry downs of liquid mixes, chemical dispersions and wear on machine components.

X-Ray Fluorescence (XRF)
The elements present in a sample (those from Sodium through Uranium) can be simultaneously determined by this instrument. It is useful in the analysis of contaminants, stains, residues, catalysts, fire retardants, and antimicrobials.

X-Ray Diffraction (XRD)
X-Ray diffraction provides information that cannot be obtained any other way. This information relates to the crystal structure of the material and can characterize the crystalline phases present. It can also provide information pertaining to the degree of crystallization and the orientation of the material. Milliken Research utilizes two types of XRD analyzers — Wide Angle and Small Angle.

Video Light Microscope (VLM)
Examination of objects on a computer monitor. Typical samples include fabrics and yarns, machine parts, and modified surfaces.

Image Analysis
With the increasing capabilities of computers comes the ability to seek specific types of information from images that have been made of samples. Pictures are converted to image files and can then be analyzed using powerful software programs to extract data, especially information such as size, number, grouping, percent openness, and area measurements.

Contact Angle / Drop Shape Analysis System (DSA)
Contact Angle is used to characterize the wetting of a solid with a liquid. This is very useful in the development of chemicals and/or coatings that can affect the absorbency, repellency and nanostructure of textiles or additives and other solid substrates.

Seeing and understanding the properties of infinitely small particles of matter enables Milliken to see possibilities for the world at large.  The Microscopy Lab provides a lens to the future of innovation.
