Research Project: Cottonscope ® Analyses of Cotton Maturity and Fineness (CI# 12-214)

Location: Cotton Structure and Quality Research

Project Number: 6054-44000-075-14-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jan 1, 2013
End Date: Dec 31, 2013

The primary objectives of this program are 1) assess the feasibility of using the Cottonscope® image analysis-polarized light microscopy instrument to measure cotton fiber maturity (MR) and fineness; 2) determine key impacts on results (environmental, etc.); 3) develop routine analysis protocols; and 4) establish the relationships between the Cottonscope® MR and fineness and other fiber maturity and fineness instruments (e.g., AFIS).

A well-known method for fiber maturity and fineness is a cross-section image analysis and microscopy measurement. In general, typical cross-section image analysis and microscopy methods for fiber maturity and fineness can be slow and tedious to perform. A significant amount of interest internationally has been shown in a separate, “low cost,” user-friendly, rapid, precise, and accurate direct measurement of maturity and fineness. A new instrument has recently been introduced to the marketplace that measures simultaneously fiber maturity and fineness—the Cottonscope. Specific components of the plan of work include 1) obtain diverse fiber samples which represent a wide range of maturity (MR) and fineness; 2) perform Cottonscope MR and fineness measurements on the fiber samples and determine the feasibility and potential of the Cottonscope measurement for fiber MR and fineness; 3) develop various mathematical models; 4) perform comparative measurements; and determine the feasibility of predicting fiber micronaire based on the Cottonscope MR and fineness results.
