This work aims to synthesize a series of novel acyclic and/or heterocyclic systems, as precursors for dyes with potential antimicrobial activity that could be used for simultaneous dyeing and antimicrobial textile finishing. Thus, a series of novel pyridine, thiophene and pyrazolo[3,4-b]pyridine derivatives were synthesized, and their antimicrobial and textile finishing properties were studied and evaluated.

The synthesis, structure elucidation and antimicrobial activities of the newly synthesized compounds based on 4,4-dicyano-3-phenyl-but-3-enoic acid phenylamide (1) were demonstrated. The minimal inhibitory concentration in μg/mL of the compounds showed significant antimicrobial activity against most of the tested organisms. On the other hand, their spectral characteristics and fastness properties were measured and evaluated. Antimicrobial activities of the dyed fabrics in terms of inhibition zones (mm) were measured and evaluated.

A series of novel heterocyclic compounds (Schemes 1-3) were synthesized based on starting material (1). Compounds (1), 2, 4a, 8a and 9c exhibited comparable or even higher antibacterial activities than the selected standards (ampicillin), while compounds 2, 3c, 3d, 4a and 8b revealed higher antifungal activities than the selected standard (cycloheximide). On the other hand, some dyes showed high antimicrobial evaluation on the dyed fabrics (nylon 66, acetate and polyester) expressed as size (mm) of inhibition zones (Tables I-IV).

Results revealed that many hydrazo and azo derivatives were synthesized from some pyridines and thiophenes. The antimicrobial evaluation and textile finishing of the newly synthesized products revealed significant and potent values of antimicrobial activity.

All the synthesized compounds were novel and most of them exhibited higher antimicrobial activities than the selected standards antibiotics, thus are valuable for simultaneous dyeing and antimicrobial functional finishing of textile fabrics.

Examines the fourteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

The purpose of this paper is to give compiled information on previously applied cotton fabric surface modifications. The paper covered most of the modifications done on cotton fabric to improve its properties or to add some functional properties. The paper presented mostly studied research works that brought a significant surface improvement on cotton fabric.

Different previous works on surface modifications of cotton fabrics such as pilling, wrinkle and microbial resistance, hydrophobicity, cationization, flame retardancy and UV-protection characteristics were studied and their methods of modification including the main findings are well reported in this paper.

Several modification treatments on surface modification of cotton fabrics indicated an improvement in the desired properties in which the modification is needed. For instance, the pilling tendency, wrinkling, microbial degradation and UV degradation drawbacks of cotton fabric can be overcome through different modification techniques.

To the best of the author’s knowledge, there are no compressive documents that covered all the portions presented in this review. The author tried to cover the surface modifications done to improve the main properties of cotton fabric.

The purpose of this paper is to establish a suitable procedure for producing antimicrobial 100 per cent cotton textiles using zinc pyrithione. Zinc pyrithione being bacteriostatic in nature is eco-friendly and safe, both for manufacturer to apply and consumer to use.

After conducting laboratory trials, bulk trial has also been conducted, and efficacy of zinc pyrithione as bacteriostatic has been quantitatively determined. The durability of antimicrobial finish was also checked before and after repeated domestic laundry.

The findings indicated that it is possible to produce durable antimicrobial 100 per cent cotton textiles in bulk using zinc pyrithione.

Any exporting textile processing mill can directly use the findings of this work and can produce antimicrobial textiles in their factory.

Any exporting textile mill can increase their export earnings by producing antimicrobial textiles. The antimicrobial textiles are in great demand in Asia-Pacific region and have already touched exports of US$497.4m in 2015 and is projected to reach US$1,076.1m by 2026.

The textile user can get protection against pathogenic or odour-causing microorganisms using this hygiene finish in different end uses.

The work is original. Very few references are available on zinc pyrithione. First, laboratory studies were done, and bacteriostatic properties of zinc pyrithione were determined quantitatively followed by bulk trial.

Any change in physical performance of the fibre corresponds to a change in its molecular structure. Basically polyester is hydrophobic in nature due to the absence of attracting polar groups and the dense packing in its polymeric structure. Due to the dense packing in polymeric structure and lack of hydroxyl groups of polyester it does not absorb water hence breathability is poor. The possibility of using air and oxygen plasma treatments for fibre surface activation to facilitate the improvement of hydrophilicity is attempted and has been improved. The purpose of this paper is to study the possibility of engineering the multifunctional of fabrics.

The treated fabric is evaluated through measuring the ultraviolet protection factor, thermal resistance, and antibacterial activity properties. Scanning electron microscopy and transmission electron microscopy graphs show deposition of nano particles (NPs) of Chitosan, TiO₂ and ZnO onto the fibre after washing several times.

Air plasma-nano Chitosan treatment affects positively the antibacterial activity, thermal resistance of the fibre and air plasma-nano TiO₂ and ZnO the fibre protection against ultraviolet rays. Furthermore, the plasma treatment solves an environmental problem which offers safe production process and working place and decreases the unit cost.

The authors are confident that textiles will adopt this technology in the future.

A systematical review of catalyst was provided in the paper involving the definition, the sort, effect mechanism and the influence factors which followed that the application of catalyst in the textile industry in terms of dyeing, finishing and effluents treatment. Catalyst is defined as a substance that could change the rate of chemical reaction, while it is not consumed in the overall reaction. The changing of the reaction rate by means of catalyst is known as catalysis. Catalyst could assist in either acceleration or deceleration of the reaction rate. In textile processing, especially in textile wet processing such as dyeing and finishing, for example, easy care and durable press finishes, antimicrobial finishes, ultraviolet protection finishes, flame retardant finishes and water repellent finishes, various types of catalysts will be involved for achieving desired effect. However, there is a less discussion and review on the relationship on the effect of catalyst on the final properties of the textile materials. Therefore, the aim of this paper is to provide a comprehensive review of the application of catalyst on the textile wet processing and nano-catalyst was also evaluated in the extending to the opportunities and development of textile industry.

A widespread focus on the plant-based antimicrobial cotton fabric finishes has been accomplished with notable importance in recent times. The antimicrobials prevent microbial dwelling in fabrics, which causes severe infections to the fabric users. Chemical disinfectants were conventionally used in fabrics to address this challenge; however, they were found to be toxic to humans. Thus, the present study aims to deal with the utilization of phytochemical extracts from different parts of Pongamia pinnata as antimicrobial coatings in cotton fabrics.

The root, bark and stem were collected and washed several times using tap water. Then, the leaves were dried at room temperature and the root and bark were dried using an oven at 40ºC. After drying, they were ground into fine powder and extracted with ethanol using the Soxhlet apparatus. After that the extract was coated on the fabric tested for antimicrobial studies.

The results reported that the leaf extract of P. pinnata-coated fabric exhibited enhanced antibacterial property towards gram-negative Escherichia coli bacteria, followed by root, bark and stem. The wash durability test in the extract-coated fabric samples revealed that dip-coating retained antibacterial activity until five washes. Thus, the current study clearly suggests that the leaf extract from P. pinnata is highly useful to develop antibacterial cotton fabrics as health-care textiles.

The novelty of the present work is to obtain the crude extract from the leaves, bark, root and stem of P. pinnata and evaluate their antibacterial activity against E. coli, upon being coated on cotton fibres. In addition, the extracts were subjected to wash durability analysis to study the coating efficiency of the phytochemicals in cotton fabrics and a probable mechanism for the antibacterial activity of P. pinnata extracts was also presented.

Textiles are a suitable substrate for the growth of micro-organisms, especially at appropriate humidities and temperatures, when in contact with the human body. Due to the awareness that healthcare textiles enhance the quality of life, antimicrobials and antibacterial textiles have received, and continue to receive, considerable attention from researchers due to their potential to provide quality and safety benefits to many products. However, antimicrobial agents and antibacterial finishing processes have not grown in number because of possible harmful or toxic effects on humans and the environment. The application of rechargeable, safe antimicrobial agents and eco-friendly antibacterial finishing processes are being studied. This paper analyzes the disadvantages and advantages of antimicrobials and antibacterial finishing processes and finds suitable antimicrobials and antibacterial finishing processes for cotton. It is anticipated that the review will be a good resource for those who are interested in antimicrobials and biocidal textile materials, and will help to stimulate further interest in this area.

Cotton-comfortable multi-ply face mask fabrics have been developed at The University of Tennessee's Textiles and Nonwovens Development Center (TANDEC) which have a repellent finished outer spunbond (SB) polypropylene (PP) layer, a middle layer of electrostatically charged (EC) melt blown (MB) PP, and a face side of a cotton-rich nonwoven. The EC MB PP layer effectively filters out aerosols and particulate containing bacteria and viruses, thereby protecting both the wearer and other personnel in the environment. In addition, a cotton-rich nonwoven layer on the body side provides the aesthetics and comfort of cotton, and also better retains antibacterial finish for neutralizing any microbes that penetrate the EC filter media. Filtration efficiency (FE) against 0.1 μm NaCl particles and the pressure drop were determined at TANDEC. FE to water aerosol containing Staphyloccus aureus bacteria per the In Vitro Bacterial Filtration Efficiency (BFE) test and to virus (φX174) per the In Vitro Viral Filtration Efficiency (VFE) were determined at Nelson Laboratories. The percent reduction of bacteria after the BFE test was also ascertained by Nelson Laboratories by a method adapted from AATCC 100.
