Print clarity on various textile substrates is considered as image sharpness in this research. The current standard test method is a subjective test where a printed fabric is evaluated visually by one or more human subjects. To advance digital printing of textiles further, it is critical to create a quantitative evaluation method for testing print clarity (sharpness), as has been done with paper. In this paper, a quantitative evaluation of the print clarity (sharpness) of a digitally printed test pattern on textiles was created. Different colors, directions, and fabrics (substrates) were considered in the design of experiment. Eight similar weight and structure woven polyester samples along with a paper substrate were printed with MS JP7 printers using nano-pigments and printed in two directions. The resulting prints were scanned with an EPSON Expression 11000XL Photo Scanner. Several software packages, including Image-Pro and MatLab, were used to process data to analyze and compare image contrast of the test pattern under different conditions. Improved print clarity in digital printing on polyester woven fabric was explored. The newly developed test method is a quantitative test method that makes optimization of the print quality (sharpness) easier and more accurate.}, number={1}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, publisher={Informa UK Limited}, author={Li, Xingyu and Powell, Nancy B. and Michielsen, Stephen}, year={2020}, month={Jan}, pages={108–121} }

A binding-off process can be performed by manual or mechanical methods involving hand knitting, overlocking, and linking processes. Binding off also can be achieved on automated flat-knitting machines by a combination of loop transfer and racking techniques. A binding-off process on the computerized knitting machinery provides several potential benefits such as minimizing labor intensive sewing or linking processes, production of constant quality products, and other benefits. However, in order to obtain the bound-off knit edges on computerized knitting machines, it is significant to not only provide appropriate values of loop lengths and machine tensions but also to choose suitable types of binding-off methods. This research introduces three different types of binding-off processes on neck edges conducted on automated complete garment knitting machines and investigates the seam strength and elongation of the neck edges by the three binding-off methods.}, number={3}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Choi, W. and Kim, Y. and Powell, N.

Most of these nonwovens are subjected to thermal treatments to give the nonwovens their final three-dimensional forms. Therefore, it became crucial to investigate the effects of thermal treatment on sound absorption characteristics of nonwovens. In this study, the effects of the material and treatment parameters on airflow resistivity and normal-incidence sound absorption coefficient of thermally treated three-layered nonwoven composites have been studied. The material parameters included fiber size and porosity. The treatment factors included the temperature and duration. The thermally treated three-layered nonwoven composites are classified into three types based on the material content and fiber blend. Sandwich structures consisting of polylactide/hemp/polylactide and polypropylene/glassfiber/polypropylene layers were called LHL and PGP, respectively. The sample which consisted of three layers of an intimate blend of polypropylene-glassfiber was named as PGI. Both temperature and duration of thermal treatment have been found to affect air flow resistivity and sound absorption. An increase in air flow resistivity and a decrease in sound absorption have been detected with heat treatment. A similarity has been observed between the thermal behaviors of PGP and PGI, which included the same thermoplastic polymer fiber. Variation in air flow resistivity of sandwich structure nonwoven composites increased with the increase in temperature, which was not observed in the intimate blend ones. The air flow resistivity of heat-treated nonwovens followed a steeper trend compared to unheated nonwovens per change in material parameters. In terms of treatment parameters, the difference between the thermal treatment and the melting point of the thermoplastics constituent of the nonwoven composite was found to be a significant factor on sound absorption. This effect of treatment temperature on sound absorption changed with treatment duration. The sound absorptive characteristic of the nonwoven composites in terms of sound frequency underwent a change with thermal treatment due to the structural changes with exposure to high temperature. }, number={2}, journal={JOURNAL OF INDUSTRIAL TEXTILES}, author={Yilmaz, Nazire Deniz and Powell, Nancy B. and Banks-Lee, Pamela and Michielsen, Stephen}, year={2013}, month={Oct}, pages={231–246} }

Although seamless knit is established in intimate apparel, extension of the technology to outerwear has been slow to attract consumers.

This research investigates the possibilities of resist-dyed structures on knitted fabrics, including garments created by computerized seamless-knitting technology. Resist-dyeing techniques have been traditionally created by numerous hand methods around the world, such as wax resist, yarn resist, and tied-fabric resist.

The Crawford and DiBenedetto model (2003) was used as the conceptual framework for the study and data was collected using secondary and primary data sources. A total of 24 global companies, based in the United States, comprised the sample for this study. Each company's new textile product development processes, practices, and new products were examined, with identification of key new product development concepts being utilized. Results indicated that companies were utilizing new product development (NPD) processes as a competitive tool, but are using a combination of NPD strategies to develop and launch products in the global marketplace.}, number={2}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Powell, N.
