Methods for investigation of fiber structure

The different techniques for investigation of fiber structure Introduction: Cotton, silk, and wool which are the fibers commonly utilized in the textile industry have recently found competitors in various synthetic products, viz., rayon, nylon, and therefore the rest. The fiber molecular structure is investigated by a special method. employing a different method to work out the chemical groups, molecular spacing, chemical bonding, crystallinity, orientation, spiral turns, molecular packing, the cross-sectional shape of the fiber.

Methods for investigation of fiber structure :

1. X-ray diffraction method

1. Infra-red radiation absorption method

1. Optical microscopic method

1. Electron microscopic method

1. Nuclear magnetic resonance method (NMR)

1. Thermal Analysis

1. Density Measurement

1. Chemical Test

1. Analysis of general physical properties.
