Abstract

Purpose

This review deals with the pros and cons of ultraviolet (UV) radiation on human beings and the role of textile clothing and the chemicals used for textiles to protect from their harmful effects.

Design/methodology/approach

UV radiation (UVR) which has further divided into UVA, UVB, and UVC. Almost 100% of UVC and major portion of UVB are bounced back to stratosphere by ozone layer while UVA enters the earth atmosphere. Excessive exposure of solar or artificial UVR exhibit potential risks to human health. UVR is a major carcinogen and excessive exposure of solar radiation in sunlight can cause cancer in the lip, skin squamous cell, basal cell and cutaneous melanoma, particularly in people with the fair skin.

Findings

This article aims to provide a comprehensive overview of the harmful effects of UVR on human skin, factors affecting UV irradiance and factors affecting UV protection offered by textile clothing.

Originality/value

Effect of fiber properties, yarn properties, fabric construction, fabric treatments and laundering has been reviewed along with the identification of gaps in the reported research. A comparison of inorganic and organic UV absorbers has also been given along with different testing and evaluation methods for UV protective clothing.

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

This paper aims to provide an analysis of National Accountability Ordinance 1999 (NAO) after June 2022 amendments. It raises a key question whether the new legislation is effective and improves anti-corruption operating system in Pakistan.

Design/methodology/approach

This paper performs an analysis of recent amendments incorporated in NAO from the observations of superior courts, United Nations Corruption Convention and Financial Action Task Force (FATF) guidelines and also evaluates new legislation in terms of effectiveness in anti-corruption campaign.

Findings

This paper finds that ample amendments are inessential, and thus may largely jeopardize accountability process; changes appear to be intentionally crafted to benefit some selected group of people: the definition of asset is compressed; the onus of proof is shifted on the informer; and provisions of money trail, foreign evidence and protection of approver are abolished; such changes defy to the UN Corruption Convention and FATF guidelines. A legislation endorsed from all stakeholders is suggested; additionally, improved strategies proposed to strengthen accountability process while keeping in view the constitutional issues relevant in the course of anti-corruption investigations.

Originality/value

This paper is unique in the context of the anti-corruption strategies in Pakistan, highlighting the legal laxness of new government regarding corruption and money laundering.
