Washfastness and crockfastness values were evaluated to study the effects of binder and process parameters on pigment printing. Acrylate-and butadiene-based binders, and three different colorants, were used for pigment printing on 100% cotton fabrics. Sixty-six pigment printed fabrics were evaluated for washfastness and crockfastness by standard test methods. Fastness values were evaluated based on binder, softener, fixator, process, fastness developer, pH, and curing temperature/ time. Results indicated that wet crockfastness values were dependent on the processing parameters. In addition, using butadiene-based binder and adding fixator into the printing paste had significant effect on improved fastness values.
The understanding of preferences toward fabrics is an important step of understanding consumer behavior of apparel. This article presents a work to study the preferences toward summer-shirt fabrics and their characteristics, particularly the gender impact, visual impact, and tactile impact toward the preference of fabrics are separately studied. Furthermore, the stability of the preference from different genders was investigated as well. To achieve these goals, the visual system and the tactile system were employed for testing male and female preferences of fabrics and the characteristics of fabrics. The two contributions of this work are as follows: (1) the factors which impact the preference of a fabric were figured out, and their relationship become a good reference for an apparel designer, and with them, a piece of apparel with preferred fabrics is able to be produced; and (2) the textile development regarding the visual sense and tactile sense will become more targeted and customized in favoring different customers.
BackgroundThe novel amido and O-ferrocenyldithiophosphonates [FcP(S)(SH)(NHR1)] (Fc = Fe(η5-C5H5)(η5-C5H4), R1 = 1-(4-fluorophenylethyl and benzyloxycyclopentyl) and [FcP(S)(OR2)S−][H3N+C(CH3)3] (R2 = myrtanyl) were synthesized by the reaction of [(FcPS2)]2 (Fc = Fe(η5-C5H5)(η5-C5H4)) and chiral amines, such as (S)–(−)-1-(4-fluorophenylethyl) amine and (1S,2S)-(+)-benzyloxycyclopentyl amine, and of (1S), (2S), (5S)-myrtanol in toluene. The reaction of ferrocenyldithiophosphonates and [Cu(PPh3)2]NO3 or AgNO3 and PPh3 gave rise to copper(I) and silver(I) complexes in THF. [Ag2{FcP(OMe)S2}2(PPh3)2] and [Cu(PPh3)2]NO3 were embedded into nanofibers and their antimicrobial activities on fibers were also investigated.ResultsThe compounds have been characterized by elemental analyses, IR, NMR (1H-, 31P-) spectroscopy as well as MS measurements. Nanofibers were obtained by electrospinning method which is the simplest and most effective method to produce nanoscale fibers under strong electrical field. Antimicrobial activity of the compound 5, [Ag2{FcP(OMe)S2}2(PPh3)2], and [Cu(PPh3)2]NO3 on fibers were studied.ConclusionsIn this study, the new dithiophosphonate ligands were synthesized and utilized in the preparation of copper(I) and silver(I) complexes with ferrocenyldithiophosphonate and triphenylphosphine. Then, the compounds [Ag2{FcP(OMe)S2}2(PPh3)2] and [Cu(PPh3)2]NO3 were added into the PAN solutions (Co-PAN dissolved in dimethylacetamide) and the solutions were electrospun onto microscope slides and PP meltblown surfaces. Antimicrobial activity of the compounds [Ag2{FcP(OMe)S2}2(PPh3)2] and [Cu(PPh3)2]NO3 on fibers were determined in vitro against two indicator strains; M. luteus NCIB and E. coli ATCC25922. The obtained results indicated that these metals showed moderate level antimicrobial activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
