Abstract

Purpose

This study aims to investigate the effect of the copresence of ferrous (Fe2+) ions and sodium dodecyl sulfate (SDS) on the activity of an amylase enzyme during the desizing of greige viscose fabric for potential industrial applications. The removal of starches is an essential step before processing the fabric for dyeing and finishing operations. The authors tend to accomplish it in eco-friendly and sustainable ways.

Design/methodology/approach

The experiments were designed under the Taguchi approach, and the results were analyzed using grey relational analysis to optimize the process. The textile properties of absorbency, reducing sugars, bending length, weight loss, Tegawa rating and tensile strength were assessed using the standard protocols. The control and optimized viscose specimens were investigated for certain surface chemical properties using advanced analytical techniques including scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermal gravimetric analysis (TGA).

Findings

The results demonstrate that the Fe2+ concentration and process time were the main influencing factors in the amylolytic desizing of viscose fabric. The optimized process conditions were found to be 0.1 mm Fe2+ ions, 3 mm SDS, 80°C, 7 pH and 30 min process time. The copresence of Fe2+ ions and SDS promoted the biodesizing of viscose fabric. The SEM, Fourier transform infrared spectroscopy, XRD and TGA results demonstrated that the sizing agent has efficiently been removed from the fabric surface.

Practical implications

The amylase desizing of viscose fabric in the presence of certain metal ions and surfactants is a significant subject as the enzyme may face them due to their prevalence in the water systems. This could also support the biodesizing and bioscouring operations to be done in one bath, thus making the textile pretreatment process both economical and environmentally sustainable.

Originality/value

The authors found no report on the biodesizing of viscose fabric in the copresence of Fe2+ ions and the SDS surfactant under statistical multiresponse optimization. The biodesized viscose fabric has been investigated using both conventional and analytical approaches.

Abstract

Purpose

The efforts of researchers in the 21st century have been devoted to developing novel approaches to leave planet earth green for future generations. This study aims to report the synthesis of microcapsules from natural essential peppermint oil and their application to a bleached polyester and cotton (PC) blended fabric.

Design/methodology/approach

Microcapsules were prepared by a complex coacervation process and applied through the conventional pad-dry-cure method. The liquid suspension of the microcapsules was examined by optical microscopy to investigate the surface morphology of the microcapsules. Scanning electron microscopy was used to examine the surface morphology of the fabric after the application of the microcapsules. The finished fabric was checked for its mosquito repellent activity at the lab scale using a standard test protocol (cage test) by inserting a human arm and hand enfolded with microcapsules treated fabric.

Findings

PC fabric treated with 6% microencapsulated peppermint oil at zero wash showed 95.3% repellency against mosquitoes, and after 30 washes, the repellency was 85.8% which confirmed the durability of the developed finished fabric. The finished samples exhibited excellent air permeabilities and absorbencies.

Originality/value

This study successfully developed peppermint oil microencapsulated fabric with excellent efficacy against three mosquito species.

Abstract

Purpose

Chitosan is widely considered as a natural polymer and a diverse finish to impart antibacterial property and enhanced dye uptake of textiles. Herein, the authors have investigated the feasibility of using chitosan/starch blend as a thickener in screen printing of cellulosic fabrics with some natural dyes.

Design/methodology/approach

The polymeric blend of chitosan/starch was prepared and used as a thickener for screen printing with three natural dye extracts, namely, Curcuma tinctoria (turmeric), Beta vulgaris (beet) roots and Lawsonia alba (henna) leaves on cellulosic fabrics like cotton and viscose. The viscosity and rheological properties of print paste as a fresh and after overnight shelving were examined. The influence of polymeric blends on cellulosic fabrics' print properties was inspected by determining their colorfastness, rubbing fastness, tensile strength and antibacterial activity.

Findings

The results depicted that chitosan/starch blend as printing thickener increased the shade depth with good wet and dry rubbing fastness for all the test natural dyes. The antibacterial activity of resultant printed cellulosic fabrics was found to be satisfactory against broad-spectrum bacterial strains.

Practical implications

This study's outcome is the development of chitosan blend thickeners to print the cellulosic fabrics with indigenous natural dyes.

Originality/value

The authors found no previous report on the synthesis of chitosan-based antibacterial blend thickeners with three distinct natural dyes and their application in screen printing of native and regenerated cellulosic fabrics of cotton and viscose, respectively.

Abstract

Purpose

This study aimed to present fabrication of novel poly(lactic acid) (PLA) mediated chitosan nanoparticles (CNPs) and their impregnation on cotton fabric for enhanced antibacterial and physical properties.

Design/methodology/approach

The PLA-CNPs were characterized using scanning electron microscopy, energy dispersive x-ray spectroscopy, Fourier transform infrared (FTIR) spectroscopy and zeta size analysis. The prepared PLA-CNPs were impregnated on cotton fabric via pad-dry-cure method. The finished cotton fabric was then characterized for its antibacterial activity, functional and other physical textile properties.

Findings

The spectral and optical properties demonstrate that the NPs expressed spherical morphologies with an average particle diameter of 88.02 nm. The antibacterial activity of treated fabrics ranged between 75 and 90 per cent depending on the concentration of PLA-CNPs.

Practical implications

Because of enhanced awareness and desire for ecofriendly products, the use of sustainable and functional textiles is increasing day by day. For the said purpose, industries are using different chemical treatments to achieve desired end functionality. Currently, different synthetic antibacterial agents are in practice, but they lack sustainable approach to save the environment. In this study, the researchers have developed PLA mediated CNPs for sustainable antibacterial and physical properties of treated cotton fabric.

Originality/value

To the best of the authors’ knowledge, this is first attempt to fabricate PLA-incorporated CNPs for application on cotton fabric followed by a detailed characterization.

Abstract

Purpose

The purpose of this paper is to highlight the status (information services, infrastructure, budget, collection and staffing) of public girls’ high school libraries of the Lahore city. Lahore is the second largest and hub of educational institutions in Pakistan. Resource-based learning is the basic right of all citizens. School libraries support teaching and learning with best available information resources. In Pakistan, fewer studies have reported the status of school libraries, and keeping in view the significance of early education, the present study highlights the situation through a qualitative lens.

Design/methodology/approach

For an in-depth analysis of the situation, qualitative research approach was used. The data were collected through interviews and observation technique. Additionally, focus groups were conducted with the students of grade IX and X to find their school libraries’ perceptions.

Findings

The findings revealed that the overall status of school libraries was unsatisfactory. Libraries were facing many problems such as lack of staff, budget, place and poor infrastructure issues. It was also found that economic geographical location of schools was not the factor affecting the status of libraries; rather, the schools’ head was mainly responsible for the better condition of the libraries.

Research limitations/implications

The study has implications for educationists, librarians, library schools and library professional organizations to make effective policies. However, the findings cannot be generalized and can be applicable in a similar context.

Originality/value

The study is based on MPhil thesis and is significant to be added in global school librarianship literature.

Abstract

Purpose

The purpose of this study is to investigate the impact of post content, post media and post scheduling strategies on online engagement on Twitter in context of micro celebrities in Pakistan.

Design/methodology/approach

For this research, micro celebrities of Pakistan have been defined as the target population. Secondary data consisting of 464 tweets from walls of six micro celebrities belonging to both genders and diverse set of socio-political fields was collected. Tweedie estimation analysis was run to accept or reject the hypotheses. Mean values with standard deviations were utilized to analyze the different engagement patterns of dichotomous variables (content type, content language, mentions, hashtags, text, images, links, videos, hour of the day and day of the week) on online engagement.

Findings

Content type, content language, content length, hashtags, mentions, images, links, videos, hour of the day and day of the week have been found to have a significant relationship with online engagement on Twitter.

Research limitations/implications

First, the study has been conducted in context of micro celebrities on Twitter. It did not include influencers on other social media networks. Second, study considered only quantitative aspects of engagement based on secondary data ignoring qualitative aspects of phenomenon due to time and methodology constraints. Third, study did not include link clicks as a measure of engagement as clicks data is not publicly available on the posts.

Practical implications

The study contributes significantly to find out valuable “micro celebrity” strategies in Pakistan. The study suggests micro celebrities to tweet soft content in Urdu language along with relevant hashtags and mentions to get higher engagement on their tweets. Further, tweets should contain maximum number of characters. Micro celebrities should not insert images, links and videos in their tweets as these media types result in lower engagement on Twitter. Micro celebrities should tweet at low hours and weekends.

Social implications

As this study focuses on investigation of better engagement practices for micro celebrities, it will help general public to express themselves more effectively through social media.

Originality/value

First, this is the first study that investigates the online engagement model for micro celebrities. Second, the online engagement model designed in this study has yet not been investigated to best of our knowledge. The theoretical model combines multiple engagement factors discussed in previous studies conducted on Facebook, YouTube, Instagram and Twitter.

Abstract

Purpose

This study aims to investigate what past scholars have learned about Muslim consumer compliance behaviour in Islamic banks and identify what future research is needed. In addition, it also explores the relationship model between the previously studied determining factors and the customer’s Sharia compliance behaviour.

Design/methodology/approach

This study used a bibliometric–systematic literature review analysis using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) technique by reviewing the articles published from 2013 to 2023. The PRISMA procedures involved several stages, including identification, screening, eligibility, analysis and conclusion based on the findings.

Findings

The results found that customer Sharia compliance behaviour determinants in Islamic banks are attitude, subjective norms, perceived behavioural control, Islamic financial literacy, religiosity, consumer conformity, Islamic branding and behavioural intention. Interestingly, the results indicated that such factors as consumer conformity, Islamic branding and sustainable intentions are less discussed.

Practical implications

Decision-makers in Islamic banks must use digital technology to offer better service and make operations more reachable for customers to access information, complete transactions and manage their accounts by Sharia principles. Therefore, the bank needs to continually produce innovative products and services so that customers have a greater variety of options to suit their Sharia-compliant financial needs. Theoretically, this study has contributed by finding the main critical domains influencing customers’ Sharia compliance behaviour, such as attitudes, subjective norms, perceptions of behavioural control, knowledge of Islamic finance, religiosity, consumer conformity, Islamic branding and behavioural intentions. Then, it makes a theoretical contribution by establishing a model that explains how customers make decisions based on Sharia-related factors in the context of their purchases.

Originality/value

Past studies focused on the Sharia compliance behaviour in paying Zakat for takaful customers. Therefore, this study provides critical factors of Sharia compliance behaviour on conformity, Islamic branding and sustainable intention regarding unexplored consensus on the determinants and outcomes of customer Sharia compliance behaviour of Islamic banking.

Abstract

Purpose

The purpose of this study is the chemical grafting of β-Cyclodextrin (β-CD) onto silk fabrics by the use of butane tetracarboxylic acid (BTCA) as a crosslinking agent and nano-TiO2 (NTO) as a catalyst. The effects of different parameters involved in this particular process, e.g. β-CD, BTCA and NTO concentrations, are examined using the artificial neural network (ANN). The method is evaluated for its ability to predict certain properties of treated fabrics, including grafting yield, dry crease recovery angle (DCRA) and wet crease recovery angle (WCRA), tensile strength, elongation at break and methylene blue dye absorption.

Design/methodology/approach

This study was conducted to describe the cross-linking of silk with 1,2,3,4-BTCA as a crosslinking agent in a wet state at low temperatures using NTO catalyst to improve the dry and wet wrinkle recovery (DCRA and WCRA) of silk fabrics. An ANN was also used to model and analyze the effects of BTCA, β-CD and NTO concentrations on the grafting percentage and some properties of the treated samples.

Findings

According to the results, the wet and dry wrinkle recovery of the silk fabrics was improved for about 38% and 11%, respectively, as compared to the non-cross-linked fabrics, without significantly affecting the tensile strength retention of the fabrics.

Originality/value

This research model and analyze the effects of BTCA, β-CD and NTO concentrations on the grafting percentage and some properties of the treated samples for the first time.

Abstract

Purpose

Phishing is a well-known cybersecurity attack that has rapidly increased in recent years. It poses risks to businesses, government agencies and all users due to sensitive data breaches and subsequent financial losses. To study the user side, this paper aims to conduct a literature review and user study.

Design/methodology/approach

To investigate phishing attacks, the authors provide a detailed overview of previous research on phishing techniques by conducting a systematic literature review of n = 367 peer-reviewed academic papers published in ACM Digital Library. Also, the authors report on an evaluation of a high school community. The authors engaged 57 high school students and faculty members (12 high school students, 45 staff members) as participants in research using signal detection theory (SDT).

Findings

Through the literature review which goes back to as early as 2004, the authors found that only 13.9% of papers focused on user studies. In the user study, through scenario-based analysis, participants were tasked with distinguishing phishing e-mails from authentic e-mails. The results revealed an overconfidence bias in self-detection from the participants, regardless of their technical background.

Originality/value

The authors conducted a literature review with a focus on user study which is a first in this field as far the authors know. Additionally, the authors conducted a detailed user study with high school students and faculty using SDT which is also an understudied area and population.
