The goal of the proposed project is to employ the fundamental principles of color science and coloration technology to characterize the measured color of specific Nike products, made from polyesters substrates, with respect to the quality of water used in the process. The main objective is to provide a repeatable approach to matching reference target colors within a production setting and among different sites and understanding the role of water hardness on the outcome of the process. This work is expected to improve the understanding of process parameters and in turn enhance the agreement between predicted and measured colors of products as a function of processing parameters. It will also improve the agreement among results reported by various suppliers.

The present proposal has the objective to develop, validate and implement an imaging system for the color quality control and assessment of Operation Enduring Freedom (OCP) camouflage substrates. This work comprises the following main components: 1) Obtaining a statistically valid set of pass and fail responses for a large set of camouflage substrates from a group of expert color assessors that repeat their judgments on multiple trials which will be used to train the system. 2) Developing a numerical algorithm based on an imaging technique that utilizes the above visual criteria to establish instrumental acceptability boundaries. 3) Comparison of the performance of the numerical models used in the imaging techniques against visual judgments for a new set of test samples. 4) Prediction of P/F judgments for a variety of substrates. In order to improve the effectiveness of the proposed technique, different types of material (woven, knitted, nonwoven, & different blends) that are commonly utilized in the production of camouflage material in different sectors, should be made available to be visually rated and to train the system.
The thrust of this 1-year project is to examine processes and mechanisms leading to improvements in the wet and dry crock fastness on cotton, while maintaining the color gamut. In this regard, fundamental studies in ink/substrate interactions will be undertaken using instruments in the NCSU Surface Science Laboratory. These studies will involve the 1) comparison of Lubrizol (LZ) Gen 1/Gen2 and rotary screen pigment inks on cotton and 2) evaluation of LZ binder design, ink formulation and pretreatment using SPECS XPS, TOF-SIMS, and FIB-SEM methods.
The objectives of this proposal are two-fold. The first is to determine a commercially feasible way to prevent excess cationic sites on cationized cotton. The second objective is to develop a mathematical model that will allow the optimal cationization level to be calculated for a specific dye formula.
The objective of this investigation is to characterize the Sponsor's pre-treatment process by 1) performing an assessment and comparative analysis of the interaction between the pre-treatment and various commercially available inks on textiles and 2)characterizing the color shift that sometimes occurs with dark colored textiles following pre-treatment application.
The proposal is aimed at developing and deploying a rapid, accurate, and repeatable digital color assessment technology and image processing solutions to analyze color attributes and control quality of universal camouflage print patterns. Phase I of this project, funded by the US Army Soldier Equipment Division, aims to develop a working protocol for the instrumental assessment of Military Textiles that improves the consistency of quality control measures as well as communication throughout the supply chain and supports industrial applications and decision making process. This Phase II proposal aims to extend the work initiated during Phase I activity and deliver a reproducible instrumental methodology, verified through multiple site assessments and combine the technology with statistically valid perceptual assessments of the camouflage fabrics.
The US Army Solider Equipment division requires a rapid, accurate, repeatable and reproducible instrumental assessment protocol for the Universal camouflage print fabric. This proposal aims to deliver an instrumental methodology that can be implemented into the camouflage fabric supply chain rapidly and at reasonable cost.
The primary goal of the proposed research is to develop an accurate and precise integrated color control system that can be easily implemented throughout the US textile industrial manufacturing complex, from product designer through to merchandiser, dyer, retailer and consumer. Fundamental research in the following areas must be addressed to achieve this goal: 1) Develop illuminant data that correlate with the color rendering of lighting used in standard light booths (especially daylight simulators) and lighting used in retail stores, 2) Develop an accurate color inconstancy model and integrate it into color formulation software, 3) Establish the minimum possible error in color difference assessment via a well-controlled, statistically valid color difference experiment that is replicated by at least 3 independent observe panels from different regions of the world (U.S., Asia and Europe).
The current grant application is submitted by North Carolina State University and Oak Ridge National Laboratory. The proposal is aimed at developing and deploying an extensible optical reader technology and image processing solutions to identifying and analyze textile tags for the US Textile and Apparel Industry as well as US Customs through integration of a robust reader system into a design that supports commercial and industrial applications.
