The thicknesses of the screen meshes were of 125.7 microns and 230.48 microns respectively. The chemicals used in this research were sodium alginate, soda ash and urea. The printed colors were measured with a X-rite i1-pro reflectance spectrophotometer (illuminant D65 and 10 degree observer function) for the colorimetric measurements (L*, a* and b* values). The results showed that fabric samples pretreated with padding mangle produced better results (i.e., L*, a* and b* values) compared to fabric samples pretreated with screens.}, booktitle={Breaking Boundaries}, publisher={Iowa State University Digital Press}, author={Chakraborty, Samit and Saha, Kowshik and Parillo-Chapman, Lisa}, year={2022}, month={Sep} } @inbook{biswas_banerjee_saha_anjum_2021, title={Lignin-based nanoparticles}, url={http://dx.doi.org/10.1016/b978-0-12-824364-0.00007-1}, DOI={10.1016/b978-0-12-824364-0.00007-1}, abstractNote={Lignin is one of the most abundant bio-based macromolecules found in nature, second best to cellulose. Researchers all around the world have been putting their best efforts to extract the optimum potential of this abundant material, which could allow us to incorporate a cost-effective and eco-friendly approach to our lives. With the upcoming surge of awareness on sustainability, it is important to understand lignin as one of the most precious materials in today's times. This chapter specifically is dedicated to lignin as a wonder material and understanding its significance in light of the present context. The chapter starts with an introduction to lignin and its importance in guiding toward a sustainable future. Consequently, sources from where lignin can be effectively extracted have been discussed. A discussion on the composition, structure, and property of lignin has been put forward for the readers to get adequate clarity on the fundamentals. Furthermore, the chapter proceeds in describing the methods of synthesizing nanoparticles from lignin that involves conventional and green methods. Once the base is all set for the readers to understand the science from a materials perspective, specific applications have been discussed in this chapter based on the research that has been performed to date. On the basis of a meticulous understanding of lignin and its importance in nanomaterial applications, challenges and future directions have been proposed to inspire the readers to dive deep into the research area of lignin-based applications.}, booktitle={Biopolymeric Nanomaterials}, publisher={Elsevier}, author={Biswas, Manik Chandra and Banerjee, Debjyoti and Saha, Kowshik and Anjum, Samin}, year={2021}, pages={203–219} } @article{haar_saha_patwary_nguyen_aryal_2021, title={Measurement of Aluminum and Chemical Oxygen Demand in the Effluent of Mordanted Cotton Against Environmental Regulations}, volume={39}, url={http://dx.doi.org/10.1177/0887302x20939662}, DOI={10.1177/0887302x20939662}, abstractNote={ Despite toxicity concerns of chemical mordants used in natural dyeing, there is limited research on the measurement, quality, and safe disposal of the chemical mordant effluent. This study measured the aluminum ions across the premordanting process of cotton print cloth using inductively coupled plasma mass spectrometry and calculated the oxidizable organic matter in the effluent through chemical oxygen demand (COD). The amount of aluminum absorbed by the cotton print cloth was low (2.31%–5.16%). The effluent COD was 23.91g COD/kg. Upon neutralization of the acidic condition, the aluminum in the effluent met discharge to freshwater regulations, and the COD met discharge to U.S. municipal sewage systems. However, the Global Harmonized System restricts aluminum acetate dibasic from organic certification due to its boric acid content. The high mordant concentration in the effluent supports the reuse of mordant baths but not direct disposal to the land or standing waters. }, number={3}, journal={Clothing and Textiles Research Journal}, publisher={SAGE Publications}, author={Haar, Sherry and Saha, Kowshik and Patwary, Sarif and Nguyen, Tuyen Duong Thanh and Aryal, Santosh}, year={2021}, month={Jul}, pages={206–215} } @inproceedings{saha_haar_2020, title={Measurement and Quality of Wool Mordant Effluent}, url={http://dx.doi.org/10.31274/itaa.11731}, DOI={10.31274/itaa.11731}, abstractNote={Three mordant concentrations, 7%, 12%, and 17% by the weight of fiber (wof) were examined. The effluent characteristics of chemical oxygen demand (COD) and total organic carbon (TOC) were also measured. ASTM D5673-16 Inductively Coupled Plasma Mass Spectrometry was used to measure the Al ions in the treated liquors and in the substrates. COD and TOC were measured using the COD 8000 method and the TOC analyzer. Both for fabric and yarn, the Al remaining in the substrate decreased with an increase in PAS. The 7% wof PAS concentration was significantly more efficient (p<0.050) compared to the often recommended 12% concentration. This research supports the use of PAS as a mordant for the selected wool substrates when the effluent is neutralized. Further studies could investigate lower concentrations of PAS, the feasibility of reusing the treated liquors, and the impact of PAS amount to dye color parameters.}, booktitle={Pivoting for the Pandemic}, publisher={Iowa State University Digital Press}, author={Saha, Kowshik and Haar, Sherry J}, year={2020}, month={Dec} } @phdthesis{saha_2019, title={Measurement of aluminum ions across the mordanting process of wool substrates with potassium aluminum sulfate and effluent characterization}, url={https://rgdoi.net/10.13140/RG.2.2.15933.95209}, DOI={10.13140/RG.2.2.15933.95209}, journal={Krex}, school={Unpublished}, author={Saha, Kowshik}, year={2019} }
