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

This study aims to prepare UV protection and hydrophobic fabric through modifying cotton fabric by graphene oxide and silane coupling agent. The graphene oxide and silane coupling agent (KH570) are anchored on the cotton fabric by a stable chemical bond.

Design/methodology/approach

Graphene oxide was prepared by modified Hummers method. The fabric sample was treated with graphene oxide and silane coupling agent KH570 using simple dipping-padding-drying method. The effects of the dosage of graphene oxide, silane coupling agent KH570 and curing temperature were determined by single variable experiment and orthogonal experiment, The UVA and UVB transmittances in ultraviolet light of the sample fabric were characterized, and the contact angle test method with water was used to indicate the hydrophobicity of the sample fabric. The structure and surface of the fabric were analyzed using Fourier-transform infrared spectroscopy and scanning electron microscopy.

Findings

The cotton fabric was successfully modified by graphene oxide and silane coupling agent KH570. Compared with the untreated fabric, the surface of the fabric was smooth, and there was no gap on the fiber. The graphene oxide, silane coupling agent KH570 and cotton fabric combined tightly. The UPF value of the modified fabric was 50+, and the contact angle reached 138.1°. It had excellent UV protection and hydrophobic properties.

Research limitations/implications

Although graphene oxide and silane coupling agents KH570 had successfully endowed the cotton fabric with good UV protection and hydrophobic properties, graphene oxide and silane coupling agent KH570 are expensive and used in large quantities. There are certain limitations in the actual life and production process.

Practical implications

After treating with silane coupling agent, the hydrophilic fabric treated with graphene oxide is being translated into hydrophobic, and graphene oxide bonded with cotton. The modified fabrics also have excellent UV protection. This fabric can be used for outdoor sports such as clothes and tents.

Originality/value

Cotton fabric treated with graphene oxide generally by simple dip-dry-cure method is hydrophilic and graphene oxide is easy to drop. The usage of silane coupling agent KH570 as a crosslinking agent to link graphene oxide and cotton fibers has not been reported yet. The modified fabrics have both UV protection and hydrophobic properties.

Abstract

Wool is a suitable medium for growing bacteria and fungi under favorable temperature and humidity conditions resulting in wool degradation and skin irritation or infections. Several investigations have been applied to impart antimicrobial finish of wool fabrics based on organic chemicals, but they are not environmental friendly. The present investigation aims to study the influence of treatment with metal ions of silver nitrate, cadmium chloride and copper sulphate penta hydrate as well as silver nanoparticles, by nanolayer condensation, on wool fabrics pretreated with phosphoric acid, for improvement of its properties. Wool treated with the aforementioned methods showed antimicrobial activity, UV-protection properties and improvement in conductivity. Changes in surface morphologies were also observed.

This study aims to study the simultaneous treatment of polyethylene terephthalate (PET) fabric with sodium hydroxide (NaOH) and TiO2 nanoparticles (NPs).

Abstract

Purpose

This study aims to study the simultaneous treatment of polyethylene terephthalate (PET) fabric with sodium hydroxide (NaOH) and TiO2 nanoparticles (NPs).

Design/methodology/approach

PET fabrics loaded by TiO2 NPs were investigated by the use of scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and Fourier transformed infrared spectroscopy (FT-IR). Factors affecting the finishing process such as NaOH and TiO2 NPs concentrations, finishing duration and temperature were discussed.

Findings

The finished PET fabrics imparted new properties such as antimicrobial and ultraviolet protection factor protection, what is undoubtedly will increase the spread of this type of fabric and its use in new areas.

Research limitations/implications

The method used mainly depends on activating the surface of PET fabrics by a chemical method, specifically NaOH to cause partial decomposition, which may lead to an environmental impact.

Practical implications

The obtained results revealed that the simultaneous treatment of PET fabric with NaOH and TiO2 NPs showed antimicrobial and UV protection properties. They exhibited a strong antimicrobial activity and UV protection efficiency even after five washing cycles, indicating excellent laundering durability.

Originality/value

The approach has simplicity and implementability on an industrial scale without cost investment.

This paper aims to investigate the dyeability of tussah silk fabric with lotus seedpod extract as the source of nontoxic and eco-friendly dyestuffs and functional agent.

Abstract

Purpose

This paper aims to investigate the dyeability of tussah silk fabric with lotus seedpod extract as the source of nontoxic and eco-friendly dyestuffs and functional agent.

Design/methodology/approach

Mordant free dyeing method was carried out using citric acid (CA) as the cross-linking agent to link the fibre and dye molecules. First, the natural pigment of oligomeric procyanidins was extracted from the lotus seedpod and then used to dye the tussah silk fabric. After the dyeing process, the dyed samples were treated with CA solution under different concentrations to improve the colour fastness.

Findings

The tussah silk fabric was successfully coloured in reddish brown through the dyeing process and charactered by using Fourier-transform infrared spectroscopy spectrometer. Moreover, lotus seedpod extract could impart excellent UV protection ability to the dyed samples, and UPF values reached up to 2000. CA dosage influenced the colour characteristics, UV protection and anti-wrinkling performance. The optimum dosage of CA was 7% (Wt.%). In addition, dyed silk fabric showed good antibacterial activity and the calculated bacteriostatic rate against Escherichia coli and Staphylococcus aureus were 83.27 and 60.2%, respectively.

Practical implications

This bio-dyeing strategy provided a simple and effective method for sustainable tussah silk fabric dyeing process.

Originality/value

This paper provides a novel dyeing strategy for mordant free dyeing and functionalization of tussah silk fabric, with lotus seedpod extract as natural pigment and CA as cross-linking agent to link the fibre and dye molecules.

Abstract

Purpose

Equisetum arvense L. (Equisetum) is a weed that is very difficult to remove because of its deep roots. The purpose of this paper is to examine the dyeability and antioxidant activity of Equisetum extracted from hot water.

Design/methodology/approach

Dry Equisetum was extracted at 100°C for 2 h, and its dyeability according to time, temperature and repetition cycle, and the mordant effect by skim milk powder were confirmed. The color change according to the K/S, fastness to rubbing, light, sweat and washing, UV protection rate and antioxidant activity were evaluated.

Findings

UV‒Vis spectroscopy showed that the Equisetum extract contained a flavonoid compound. The addition of Equisetum to artificial silk produced the greatest color difference when dyed at 60°C for 1 h, and the K/S value increased slightly after the pre-mordant treatment. In the fastness test, light and washing had no significant effect, but the fastness to rubbing was very good at Grades 4 and 5, and there was also a considerable improvement in the UV protection rate. The antioxidant activity of the extract was confirmed by an analysis of the radical scavenging ability through the DPPH (1,1-diphenyl 2-picryl-hydrazyl) and ABTS ([2,2’- azino-bis (3-ethylbenzothialzoline-6-sulfonic acid) diammonium salt]) tests.

Originality/value

These results revealed a new natural antioxidant-containing dyestuff, weed grass, which is easy to obtain, easy to use as a dyeing material and has excellent antioxidant activity in an extracted dye solution and dyeing fabric.

Abstract

Purpose

The purpose of this paper is to invent a new functional coated fabric based on nanomaterials to shield UV and IR. Multifunctional surface coatings with ultraviolet (UV)/near infrared radiations protection and waterproof were widely applied in outdoor fabrics. Herein, ultrafine TiO2 and nano-antimony doped tin dioxide (ATO) were prepared and embedded into water-based polyurethane (PU) coatings and then coated on the nylon fabric.

Design/methodology/approach

ATO was prepared using the sol–gel method and the two powders were dispersed by ball milling. The results of zeta potential and particle size distribution showed that the ultrafine TiO2 and nano-ATO could be stably dispersed in water at pH 8 with the presence of sodium polycarboxylate. The optimal process was screened out by orthogonal design and scanning electron microscopy (SEM), UV protection, thermal insulation and water-pressure resistance were tested. SEM images indicated the nanoparticles could be uniformly dispersed in the coatings.

Findings

The effect of UV prevention can get to UPF > 50, UVA < 5 per cent, which meet up with the AATCC 183-2014. Coatings can effectively lower the temperature of fabric surface by 8∼9ºC through the self-made closed test system and by 3ºC through the open test system.

Originality/value

These PU coatings are environment-friendly and adhesive to impart waterproof, UV-proof and thermal insulation properties to nylon fabrics by coating finishing.

Abstract

There is a growing demand in the marketplace for textile apparel that offers comfort and protection from the harmful effects of ultraviolet (UV) radiation. The UV rays of the sun when they come into contact with skin lead to all kinds of skin problems. The accumulated effects damage the skin’s DNA and cell function. In addition to skin cancer, excessive sun exposure also causes pre-malignant actinic keratoses, wrinkles, dark and unsightly blotches, leathery skin and prone to destabilizing the immune system. Research has shown that sun (UV) protective clothing is one of the most effective ways to protect against skin cancer. Such fabrics are specifically designed for sun protection by covering a maximum amount of skin and made from a fabric rated for its level of UV protection. Throwing on a sun protective shirt with an ultraviolet protection factor (UPF) of 30+ value is a proactive decision, which can simply help to live a healthier life. Hence, an attempt has been made in this study to visualize the effect of an application of titanium dioxide nano finish onto cotton and its blends with viscose and polyester to provide nano UV protection, without hampering the strength of the substrate.

Abstract

Purpose

The purpose of this paper is to prepare coloured superhydrophobic and ultraviolet (UV) protective nylon fabrics using nanosilica copper oxide coating.

Design/methodology/approach

In this study, brown coloured superhydrophobic nylon fabric exhibiting UV protective properties was prepared by step-wise deposition of silica nanoparticles, copper oxide and sodium stearate. The hydrophobicity of treated fabrics was characterised by water contact angle measurement and UV protection properties of fabric were assessed by Australian/New Zealand Standard. Also, a colouring effect of treatment on nylon fabric was measured using spectrophotometer.

Findings

The modified fabric not only exhibited superhydrophobicity with the water contact angle of 150.6°, but also rendered excellent protection against UV radiation. The fabric showed retention of hydrophobic and UV protection properties up to 20 washing cycles.

Originality/value

A novel method for imparting superhydrophobicity and UV protective properties along with colouration effect on nylon fabrics has been reported. This type of fabric has potential application in the field of protective clothing.
