Water is the ultimate and mostly used media during textile materials processing, especially in colouration. This study investigated the possibilities of using seawater for cotton and polyester fabrics dyeing. Single jersey fabrics made of 100 percent cotton and polyester were dyed using a standard recipe and two separate water source as dyeing mediums. It has been focused on the assessment of colour fastness to wash, perspiration, saliva, rubbing, water, light and colour difference value due to compare the efficiency of dyeing media. The results revealed that the cotton fabric dyed with seawater showed lighter shade than that of ground water sample. But for polyester fabric darker shade was obtained compared to ground water. The cotton sample dyed with sea water carried about 15% higher colour strength than ground water dyed sample but for polyester it was very negligible, only 3%. Moreover, the results of colour fastness to wash, perspiration, saliva, rubbing, water and light for seawater dyed samples of cotton and polyester were shown satisfactory outcomes having the grading of 4-5 in most of the cases. This exploration established that commercial dyeing processes were robust and can be practically transferable into the seawater medium for cotton and polyester fabrics.

Microplastics fibers shed from washing synthetic textiles are released directly into the waters and make up 35% of primary microplastics discharged to the aquatic environment. While filtration devices and regulations are in development, safe disposal methods remain absent. Herein, we investigate catalytic hydrothermal carbonization (HTC) as a means of integrating this waste (0.

In the interests of using green and sustainable chemical innovations to create sustainable products with minimized (or no) chemical hazard potential, the polyester fabric in this work was activated and functionalized with chitosan and its durability was investigated. Chitosan is a natural biopolymer derived from chitin. As it has good biocompatibility, bio-absorption, anti-infectious, antibacterial and hemostatic properties and accelerates wound healing, it is increasingly being researched for the antimicrobial treatment of textiles.

Background: The declaration of mpox as a Public Health Emergency of International Concern highlights the need for interventions to interrupt virus transmission, including transmission via fabrics. Current World Health Organization guidance on clothes washing is based on a general consensus of virus inactivation; however, there is uncertainty about the efficacy of laundry detergents and disinfectants or the reduction of risk achieved by washing clothes for monkeypox virus (MPXV) specifically.
Methods: This study investigates the efficacy of manual washing for inactivating MPXV from clothes.

Objective: The objective of the present study was to develop a method for sampling and detecting an adenovirus-derived gene therapy (GT) vector on isolator worksurfaces.
Methods: We used a quantitative PCR (q-PCR) to detect the viral genome in standard dilutions of pure GT product and extracts of sampled surfaces. We compared three devices for surface sampling (a cotton compress, a cotton swab and a polyester flocked swab) and performed positive control, negative control and induced contamination tests for each.
