Suitable thread type and stitch density for Ghanaian public basic school uniforms

The article by Dr. Patience Danquah Monnie and colleagues is published in the journal, Current Materials Science, 2021

2021-06-01
(Press-News.org) The quality of a sewn garment is dependent on the quality of its seams that are the basic structural element. The factors affecting seam quality in garments include sewing thread type and stitch density. Making the right choice of these helps in getting quality seams in garments. However, the choice of suitable sewing threads and stitch densities for particular fabrics can only be determined through testing.

Dr. Patience Danquah Monnie, from the University of Cape Coast, Ghana, with fellow researchers, conducted research aimed to determine sewing thread brand and stitch density suitable for seams for a selected fabric (79% polyester and 21% cotton) for public basic school uniforms in Ghana. For the research, a 2×3 factorial design was employed involving two brands of sewing threads labelled A? and B?, with three range of stitch density, 10, 12 and 14. There were a total of 81 specimens prepared from the selected fabric. The parameters, under investigation in the research, included fabric weight, strength and elongation, seam strength, seam elongation and efficiency.

With the help of the Predictive Analytic Software (SPSS), the gathered data was analyzed. For the fabric, means and standard deviations of the yarn count, weight, strength, elongation and the linear density of the sewing threads were determined. Analysis of Variance and Independent samples t-test at 0.05 alpha levels were employed in testing the hypotheses.

The researchers found that the differences for seam strength, efficiency and elongation were significant for the two sewing thread brands and the three stitch densities in both warp and weft directions of the fabric sample. The sewing thread brand B? with stitch density 14 performed best in terms of seam strength, elongation and efficiency. Concluding the research findings, sewing thread brand B? and 14 stiches per inch (SPI) were found suitable for seams for the fabric selected for Ghanaian public basic school uniforms as they had greater strength, efficiency and elongation than thread A? and SPIs 10 and 12.

It is recommended that members of the Association of Ghana Apparel Manufacturers (AGAM) and Tailors and Dressmakers Association use sewing thread brand B? with 14 SPI in uniform production in Ghana to achieve quality seams in uniforms.

Scientists identify protein that activates plant response to nitrogen deficiency

Scientists identify protein that activates plant response to nitrogen deficiency
2021-06-01
Nitrates are critical for the growth of plants, so plants have evolved sophisticated mechanisms to ensure sufficient nitrate uptake from their environments. In a new study published in Nature Plants, researchers at Nagoya University, Japan, have identified a plant enzyme that is key to activating a nitrate uptake mechanism in response to nitrogen starvation. This finding explains how plants meet their needs in challenging environments, opening doors to improving agriculture in such environments. When nitrate levels are plentiful in a plant's environment, a plant can achieve adequate nitrate uptake levels by relying ...

Mind the nanogap: Fast and sensitive oxygen gas sensors

Mind the nanogap: Fast and sensitive oxygen gas sensors
2021-06-01
Oxygen (O2) is an essential gas not only for us and most other lifeforms, but also for many industrial processes, biomedicine, and environmental monitoring applications. Given the importance of O2 and other gases, many researchers have focused on developing and improving gas-sensing technologies. At the frontier of this evolving field lie modern nanogap gas sensors--devices usually comprised of a sensing material and two conducting electrodes that are separated by a minuscule gap in the order of nanometers (nm), or thousand millionths of a meter. When molecules of specific gases get inside this gap, they electronically interact with the sensing layer and the electrodes, altering measurable ...

Declining deer population likely due to natural regulation

Declining deer population likely due to natural regulation
2021-06-01
The Yakushima sika deer (yakushika: Cervus nippon yakushimae), a subspecies of the Japanese sika deer (Cervus nippon), evolved without natural predators on the island of Yakushima, in Kagoshima Prefecture, Japan. It inhabits the forests on the island which were declared a World Heritage Site in 1993. Within the site, the yakushika has not been hunted in the past 50 years; however, since 2014, their population has been decreasing. This phenomenon is especially curious, as Japanese researchers believed that sika deer populations in Japan would not decrease without human intervention. A group of three scientists, including Hokkaido ...

Overweight or obesity worsens liver-damaging effects of alcohol

2021-06-01
Led by the University of Sydney's Charles Perkins Centre, the study looked at medical data from nearly half a million people and found having overweight or obesity considerably amplified the harmful effects of alcohol on liver disease and mortality. "People in the overweight or obese range who drank were found to be at greater risk of liver diseases compared with participants within a healthy weight range who consumed alcohol at the same level," said senior author and research program director Professor Emmanuel Stamatakis from the Charles Perkins Centre and the Faculty of Medicine and Health. "Even for people who drank within alcohol guidelines, participants classified as obese were at over 50 percent greater risk of liver disease." The researchers ...

The secret to stickiness of mussels underwater

The secret to stickiness of mussels underwater
2021-06-01
Mussels survive by sticking to rocks in the fierce waves or tides underwater. Materials mimicking this underwater adhesion are widely used for skin or bone adhesion, for modifying the surface of a scaffold, or even in drug or cell delivery systems. However, these materials have not entirely imitated the capabilities of mussels. A joint research team from POSTECH and Kangwon National University (KNU) - led by Professor Hyung Joon Cha and Ph.D. candidate Mincheol Shin of the Department of Chemical Engineering at POSTECH with Professor Young Mee Jeong and Dr. Yeonju Park of the Department ...

Researchers connect climate features to the variability of global tropical storm days from 1965 to 2019

Researchers connect climate features to the variability of global tropical storm days from 1965 to 2019
2021-06-01
Nearly two billion people live in a region where tropical cyclones (TC) are an annual threat. TCs are deadly and can cause billions of dollars in economic losses worldwide. During peak season in the Northern Hemisphere, typically July through October, about two TCs develop or are ongoing every day. However, this and overall TC frequency vary substantially year-to-year. To quantify this variability, scientists developed a metric called the tropical storm day (TSD). TSD is a collective measure of how frequently tropical cyclones develop, storm track, and cyclone lifespan, which reflects overall activity. Despite this advancement, researchers have not often studied tropical cyclone variability on a global scale. Now, ...

Biopolymer-based electrolyte for the dream of zero-pollution battery

2021-06-01
In a paper published in NANO, researchers from Guizhou Meiling Power Sources Co., Ltd., China have reviewed the recent progress in biopolymer-based electrolyte. The biopolymer materials with unique characteristics including water solubility, film-forming capability and adhesive property played a key role in the design of zero pollution lithium battery. The biopolymers mentioned in this review were polysaccharide, protein, natural rubber and other polymers. For polysaccharide, cellulose with good wettability, low cost and good mechanical properties can enhance the mechanical strength of membranes and improve interfacial stability between electrolyte and electrode. However, the porosity control of cellulose-based membranes was ...

Urban life is not to everyone's taste

Urban life is not to everyones taste
2021-06-01
Habitat change, for example through urbanisation, is one of the most important causes of biodiversity decline. By 2050, settlements and cities across the globe are predicted to increase by two to three million square kilometres - about half the size of Greenland. Natural and semi-natural habitats will thus gradually be replaced by urban habitats. How wildlife can adapt to such fundamental changes has mostly been studied for a few species groups, such as mammals and birds. "In order to make predictions about the development of biodiversity as a whole and to combat current phenomena such as insect declines, robust knowledge is also needed for other species groups," ...

Researchers measure tritium production rates in mock-up of water-cooled ceramic breeder blanket

Researchers measure tritium production rates in mock-up of water-cooled ceramic breeder blanket
2021-06-01
To realize tritium self-sustaining cycle through tritium breeding blanket has been one of the core technologies of future fusion reactor. Therefore the design and function of blanket must be validated by neutronic experiment under D-T neutron environment. But due to the scarcity of DT neutron source, and highly radioactivity during neutronic experiments, it is very difficult to validate the nuclear response of the blanket, the data of tritium production rate mainly rely on Monte Carlo simulation. Recently, a research group led by ZHU Qingjun from Institute of Plasma Physics, ...

Memory, learning and decision-making studied in worms

2021-06-01
As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how learning changes nerve cells and leads to different behaviors, researchers studied the much simpler nervous system of worms. "In this study, we can now translate neuronal activity to behavioral response," said Project Researcher Hirofumi Sato, a neuroscientist at the University of Tokyo and first author of the research paper recently published in Cell Reports. The discovery was made possible using technology that researchers describe as a "robot microscope," first developed in 2019 by researchers at Tohoku University in Miyagi Prefecture, northeastern Japan. The technique involves genetically modifying the worms ...
