“…The bursting strength of sonicated samples was determined to be 213 kPa at 70°C, 221 kPa at 65°C, 237 kPa at 60°C, and 235 kPa at 55°C, respectively. The bursting strength of the pretreated fabric increased to the same extent as the temperature decreased, as expected by the literature (Sitotaw 2017). Aside from that, the fabric strength values in samples formed by the rst and second reuse of bath chemicals are higher than in other samples.…”

Bangladesh's cotton knit industries contribute significantly to the country's economy, accounting for more than 40% of total annual export. Efficient water use in knit dyeing might result in considerable water savings and environmental sustainability. Textile wet processing consumes a lot of energy (water, gas, and electricity), generates a lot of waste, and has significant chemical costs. The cotton knit fabric used in this study was pretreated and dyed utilizing ultrasonication at a lower temperature than conventional pretreatment and dyeing techniques in an attempt to establish ecofriendly wet processing in the textile industry. For pretreatment and dyeing, bath chemicals were reused 1–3 times, and several fabric attributes including whiteness index, weight loss (%), bursting strength, color fastness to light, washing, perspiration, and rubbing were tested and compared to the traditional method. By dying with reactive dyes, the feasibility of color matching using ultrasonic aided pretreated fabric with and without reusing bath chemicals was determined. The whiteness index of the low temperature sonicated scoured and bleached fabric was found to be acceptable, with relatively low weight loss; nevertheless, the bursting strength was found to be enhanced. Color fastness to light, washing, perspiration, and rubbing of ultrasonicated dyed knitted fabric at lower temperatures than conventional techniques were found to be comparable, showing that there was no color deterioration during ultrasonication. FT-IR spectroscopy and scanning electron microscopy (SEM) revealed no significant changes in the chemical composition of cellulose or the fabric shape of pretreated and dyed cotton knit fabric after ultrasonication.

“…It is a function of fiber quality (measured as deniers), knitting patterns and types of polymers used [179]. One review on this subject concluded that bursting strength of knitted fabrics depend not only on fabric structures and fiber types, but also the yarns used [180].…”

The fabric of life: what if mosquito nets were durable and widely available but insecticide-free?

Background: Bed nets are the commonest malaria prevention tool and arguably the most cost-effective. Their efficacy is because they prevent mosquito bites (a function of physical durability and integrity), and kill mosquitoes (a function of chemical content and mosquito susceptibility). This essay follows the story of bed nets, insecticides and malaria control, and asks whether the nets must always have insecticides. Methods: Key attributes of untreated or pyrethroid-treated nets are examined alongside observations of their entomological and epidemiological impacts. Arguments for and against adding insecticides to nets are analysed in contexts of pyrethroid resistance, personal-versus-communal protection, outdoor-biting, need for local production and global health policies. Findings: Widespread resistance in African malaria vectors has greatly weakened the historical mass mosquitocidal effects of insecticide-treated nets (ITNs), which previously contributed communal benefits to users and non-users. Yet ITNs still achieve substantial epidemiological impact, suggesting that physical integrity, consistent use and population-level coverage are increasingly more important than mosquitocidal properties. Pyrethroid-treatment remains desirable where vectors are sufficiently susceptible, but is no longer universally necessary and should be reexamined alongside other attributes, e.g. durability, coverage, acceptability and access. New ITNs with multiple actives or synergists could provide temporary relief in some settings, but their performance, higher costs, and drawn-out innovation timelines do not justify singular emphasis on insecticides. Similarly, sub-lethal insecticides may remain marginallyimpactful by reducing survival of older mosquitoes and disrupting parasite development inside the mosquitoes, but such effects vanish under strong resistance. Conclusions: The public health value of nets is increasingly driven by bite prevention, and decreasingly by lethality to mosquitoes. For context-appropriate solutions, it is necessary to acknowledge and evaluate the potential and costeffectiveness of durable untreated nets across different settings. Though ~ 90% of malaria burden occurs in Africa, most World Health Organization-prequalified nets are manufactured outside Africa, since many local manufacturers lack capacity to produce the recommended insecticidal nets at competitive scale and pricing. By relaxing conditions for insecticides on nets, it is conceivable that non-insecticidal but durable, and possibly biodegradable nets, could be readily manufactured locally. This essay aims not to discredit ITNs, but to illustrate how singular focus on insecticides can hinder innovation and sustainability.

“…Although the diameters are the same, this is an expected result due to the air channel inside the hollow fiber. The bursting strength is the force that must be exerted perpendicular to the fabric surface to break off the fabric [16]. The value helps to determine the quality of the fabric and how safe it is for different applications.…”

In this study, some dimensional and thermal comfort properties, i.e. thermal resistance, water vapor permeability, and air permeability properties of interlock fabrics knitted from different cross-section shaped polyester fibers were investigated. Four polyester yarns of different fiber cross-section shapes (hollow-round, round, triangular, and W-shape) were used to produce the samples. From the results, it was found that the triangular and W-type fibers had higher fabric density values due to the denser and closer fiber settlement. The highest bursting strength value belonged to the sample knitted from hollow-round yarn, which had also the highest yarn-breaking load value. The samples knitted from both round cross-section polyester yarns had significantly higher air permeability and thermal resistance values than the other samples due to the lower fabric density values of these fabrics. On the other hand, the water vapor permeability values of the fabrics from triangular and W-type fibers were slightly higher than the others because of their lower thicknesses.
