  • Colorful Nanofibers for Advanced Apparel Application
    Materials Science Forum, 2018
    Co-Authors: Farooq Ahmed, Umair Ahmed Qureshi, Zeeshan Khatri

    Abstract:

    We report herein, the synthesis of colorful nanofibers by electrospinning and dyeing with various class of dyestuff. Results revealed that dyes impart better color yield with the acceptable colorimetric values, color yield and color fastness. Morphology of nanofibers showed smooth surface of the dyed nanofibers under SEM. Cellulose nanofibers in particular, were prepared using precursor cellulose acetate and then converted into cellulose under alkaline treatment. Results revealed that dyes impart better color yield with the adequate color yield (KS) and color fastness. Morphology of nanofibers showed smooth nanofibers after dyeing under SEM. Based results obtained, the colorful nanofiber can be a better choice for advance Apparel Applications.

  • Cold pad-batch dyeing of cellulose nanofibers with reactive dyes
    Cellulose, 2014
    Co-Authors: Zeeshan Khatri, Farooq Ahmed, Abdul Khaliq Jhatial, Muhammad Ishaque Abro, Gopiraman Mayakrishnan

    Abstract:

    The dyeability of electrospun nanofibers for Apparel Application has recently gained substantial interest. Past work focused on batchwise and continuous dyeing methods, but they required a certain temperature for dye fixation. We report on the dyeing of cellulose nanofibers by the cold pad-batch method, which offers the most economical and convenient method of dyeing cellulosic nanofibers with reactive dyes. Cellulose acetate (CA) nanofibers were fabricated via electrospinning and then deacetylated to convert CA into cellulose nanofiber. The cellulose nanofiber webs were dyed with three different classes of reactive dyes. CI Reactive Black 5 obtained the highest color yield in comparison to CI Reactive Red 195 and CI Reactive Blue 19. The dye fixation for all dyes achieved between 80 and 85 %. Except color fastness to light, washing fastness of dyed cellulose nanofibers obtained very good to excellent results. To investigate the chemical structure and fiber morphology of the cellulose nanofibers, Fourier transform infrared spectroscopy and scanning electron microscopy were used respectively.

  • cationic cellulose nanofibers preparation and dyeability with anionic reactive dyes for Apparel Application
    Carbohydrate Polymers, 2013
    Co-Authors: Zeeshan Khatri, Gopiraman Mayakrishnan, Yuichi Hirata

    Abstract:

    Continuous effort in research and development of nanofibers for Apparel usage has been focused within their functional properties only. We investigated esthetic properties by producing colored cationic-cellulose nanofibers for the very first time for the potential Application of Apparel use. The cellulose acetate nanofibers were electrospun followed by deacetylation and cationization to produce functional cationic-cellulose nanofibers and then dyed with anionic reactive dyes. The spectrophotometric measurement of dyed samples was carried out to determine color coordinates and color yield values. The cationic-cellulose nanofibers showed enhanced color yield and dye fixation without addition of an electrolyte in comparison to cellulose nanofibers. The cationization of cellulose nanofibers significantly enhanced the color yield values of around 76% at dye concentrations of 5%. Excellent color fastness results demonstrate that these new colored and breathable materials can potentially be considered as future Apparel for casual or fashion.
