SOME ADVANCES IN NONWOVEN STRUCTURES FOR ABSORBENCY, COMFORT AND AESTHETICS
Authors: Dutkiewicz Jacek 
Published: December 2023

Abstract
Modern disposable articles for personal and health care should offer excellent absorbency as well as comfort in use, need to be aesthetic and ensure discretion. There are numerous challenges facing the designers of nonwoven fabrics for absorption of body fluids, which result from various engineering contradictions. Combining all necessary functions, i.e. fluid acquisition, distribution and retention, in one uniform, simple composite made of fibers and superabsorbent polymer particles may be problematic. One can easily predict from theory that improving one parameter will result in a deterioration of another function. High-performance, multifunctional unitary structures require separation of functional components and their placement in a nonwoven web in a predetermined, oriented fashion. Some examples of such structures are proposed here and the experimental test results are discussed to demonstrate the advantages of the studied materials. The aesthetics of the finished article as well as the comfort of their use depend mainly on the bulk and mechanical properties of the absorbent core, such as integrity, softness and pliability. The paper provides some examples of engineered nonwoven webs having these desired attributes.
WICKING AND WETTING IN TEXTILES
Authors: Wiener Jakub , Dejlová Petra 
Published: December 2023

Abstract
The proposed model is based on the simplified description of the thread structure, and it works with the textile description of thread structure. The following textile parameters are used in the model: fineness of fibres, and number of fibres at the cross-section in the bundle and the filling. The formation of the liquid in the longitudinal textile is described in detail, and particular phenomena are discussed. Important parameters are used in the model of wicking. The parameters with very small influence in usual threads are disregarded. The proposed wicking model allows a functional dependence of suction height on the parameters of the fibre bundle to be expressed in analytical form.
SOUND ABSORPTION PROPERTIES OF RECYCLED POLYESTER FIBROUS ASSEMBLY ABSORBERS
Authors: Lee Youneung , Joo Changwhan 
Published: December 2023

Abstract
Sound absorption materials are generally classified into three types, porous, resonator, and panel. All of these three types are based on the theory of energy transforming from sound energy to thermal energy. In this paper, we examined the sound absorption coefficient of recycled polyester nonwovens for the purpose of substituting the conventionally used materials such as glasswool and rockwool. The use of recycled polyester nonwovens has many advantages compared to conventional sound absorbers, including reduced product cost, good handling, and environmental protection. The sound absorption coefficient of the recycled polyester nonwovens was determined by a two-microphone impedance measurement tube; the determination of the noise absorption coefficient is nothing more than the absorption energy rate of the material against the incidence energy. We have determined the relationship between the acoustic absorption values measured and the nonwoven parameters including fibre properties and web properties.

Authors: Tonin C. , Freddi G. , Aluigi A. , Innocenti R. , Vineis C. 
Published: December 2023

Abstract
This work deals with the preparation and characterisation of keratin/cellulose films prepared by coagulating polymers blends from cuprammonium solution. Films were obtained by blending keratin extracted from wool by m-bisulphite/urea solution and cellulose in several proportions. The molecular weight distributions of extracted and regenerated protein were studied by gel-electrophoresis (SDS-PAGE); the chemical structure and molecular conformation were investigated by FT-IR spectroscopy; the surface morphology of the films was observed by scanning electron microscopy (SEM).
REDUCING YARN HAIRINESS IN WINDING BY MEANS OF JETS: OPTIMISATION OF JET PARAMETERS, YARN LINEAR DENSITY AND WINDING SPEED
Authors: Rengasamy R. S. , Kothari V. K. , Patnaik Asis , Ghosh Anindya , Punekar H. 
Published: December 2023

Abstract
Reducing yarn hairiness during yarn winding by the use of air jets is a new approach, since the production rate of winding is very high and the process itself increases yarn hairiness. The Box & Behnken factorial design approach has been used to optimise the jet angle, the jet diameter, yarn linear density and the winding speed in order to reduce the yarn hairiness. A jet angle of 450, a jet diameter of 2.2 mm, 10 tex yarn and a winding speed of 800 m/min give the optimal results in terms of reducing the hairiness. A CFD (computational fluid dynamics) model has been developed to simulate the airflow pattern inside the jets with the use of Fluent 6.1 software. The air velocity around the core of the jet is the influencing factor in wrapping the hairs on the yarn body.
VOLUME POROSITY AND PERMEABILITY IN DOUBLE-LAYER WOVEN FABRICS
Authors: Elnashar E. A. 
Published: December 2023

Abstract
Clothing for garments is designed to meet both the safety and the comfort of human beings. Porosity is considered to be one of the basic features representing a textile structure. The properties of fabrics were analyzed by determining the efficiency of fabric porosity. The woven fabric multi-layer structure, the warp and weft densities, and the type of weave are factors of a woven fabric, which as porous material enables to transmit air, heat energy, and liquid perspiration. Several methods considering thread distributions have been developed to determine the woven fabric’s porosity. A mathematical model based on an ideal geometry of the porous structure of a multi-layer woven fabric has been developed.
STUDIES ON CORN STARCH FILLED POLY (STYRENE-CO-BUTYL ACRYLATE) LATEX REINFORCED POLYESTER NONWOVEN FABRIC COMPOSITES
Authors: Satheesh M. N. , Siddaramaiah  
Published: December 2023

Abstract
Poly (styrene-co-butyl acrylate) latex was prepared with a 70:30 weight ratio of styrene to butyl acrylate. Various weight percentages of cornstarch were incorporated into the prepared copolymer latex. Polyester nonwoven fabric reinforced-cornstarch-filled copolymer latex composites were manufactured by the impregnation method. The pickup ratio of latex to fabric was maintained at 3.2:1. The composites’ physico-mechanical properties, percent water absorption and percent thickness swelling were studied. The manufactured cornstarch-filled composites were evaluated for their ability to retain their shape after being moulded to the desired shape by measuring the percentage area, shape retention, hardness and resilience. It was observed that the manufactured thermoplastic composite specimens retained or increased their mechanical properties up to 20 wt% cornstarch loading.

Published: December 2023

Abstract
In this study, the toxicity of reactive dyes and dyed fabrics was investigated using spermatozoa cells in vitro. Boar semen was exposed to different concentrations of monochlorotriazinyl dyes: yellow, red and blue. The spermatozoa cells were also exposed to extracts of dyed fabrics. After 24 and 72 hours respectively, the viability of the cells was evaluated by microscopy. The mean inhibitor concentrations IC50, showing the concentration of the dye when half of the cells are dead compared to the control sample, were calculated from the viability values. After 24 hours’ exposure, the IC50 value calculated for the yellow dye was 135μg/ml, and after 72 hours 60μg/ml. The IC50 value for the red dye was 124μg/ml after 24 hours, and 46μg/ml after 72 hours. The IC50 value for the blue dye after 24 hours was 127μg/ml. After 72 hours, the blue dye caused high toxicity: more than half the cells were dead. Cotton fabrics dyed using these three reactive dyestuffs were extracted by water and analysed by the spermatozoa motility inhibition test. The viability of the cells when exposed to fabric extracts was good. However, after 72 hours’ exposure, the standard deviation and coefficient of variation values for cell viability of fabric extracts were large. The spermatozoa inhibition test indicated the toxicity of pure dyes, the dyed fabrics having no adverse effects. The spermatozoa test seems to be useful when screening different substances and when used in addition to other tests. The spermatozoa motility inhibition test can be used for textile material studies.

During the last thirty years there has been a rapidly growing interest in the field of genetic algorithms (GAs). The field is at a stage of tremendous growth, as evidenced by the increasing number of conferences, workshops, and papers concerning it, as well as the emergence of a central journal for the field. With their great robustness, genetic algorithms have proven to be a promising technique for many optimisation, design, control, and machine learning applications. This paper presents a new technique for detecting the source of fault in spinning mills from spectrograms by using genetic algorithm.
NEW APPROACH TO A THEORETICAL STUDY OF SOME OF THE PARAMETERS IN THE KNITTING PROCESS, AND THEIR INFLUENCE ON KNIT-FABRIC STITCH DENSITY
Authors: Charalambus A. 
Published: December 2023

Abstract
This paper proves relations, which concern the structure of knitted fabric by using a simple geometrical model. In addition, a series of graphics are made which allow fast, simple and effective analysis of the relations between some of the parameters of the knitting process and these of the ready-knit fabric. The quantity ‘relative geometrical prolongation of the thread length in the stitch’, introduced by me plays a significant role in this study. The relations given below allow the machine gauge to be defined; this helps to produce knit fabric with precisely calculated density by choosing appropriate values for the thread’s sinking depth and acceptable average geometrical prolongation.

Authors: Singh Kaith Balbir , Singh Singha Amar , Kalia Susheel 
Published: December 2023

Abstract
This paper deals with the graft co-polymerisation of methylmethacrylate (MMA) onto flax fibre under the influence of microwave radiation (MWR). The graft co-polymers are characterised by FTIR spectroscopy, scanning electron microscopy (SEM), thermal analysis (TGA/DTA) and X-ray diffraction (XRD). Graft co-polymers are subjected to the evaluation of some physical, chemical and mechanical properties. Graft co-polymers thus prepared are used in the preparation of phenol-formaldehyde composites. Wear resistance, tensile strength and compressive strength of composites are measured, and it is found that composites reinforced with flax-g-poly(MMA) showed better mechanical properties in comparison to composites reinforced with raw flax.
RFID TECHNOLOGY IN THETEXTILE INDUSTRY
Authors: Barburski Marcin , Czekalski Bartlomiej , Snycerski Marek 
Published: December 2023

Abstract
RFID (Radio Frequency Identification) is a wireless communication technology that is used in physical markers (RFID tags) to mark products. RFID is being increasingly applied in everyday life and thus is competing with widely used bar codes. RFID technology can be used to build systems aimed at automatic identification of tagged objects. In production- commerce plants in the textile sector it can enable strict control over both production and storage/sale processes. The best thing about RFID technology is that it is functional, with no need to 'see' the tag by the interrogator. When a tagged object enters the reading zone of an interrogator, the interrogator signals the tag to transmit its stored data to the controller via radio waves. Unlike bar codes technology, RFID can be much more effective in the process of production and storage of certain objects. Undoubtedly, both production and commerce companies in the textile branch will significantly benefit from RFID applications.
Globalization and the Miracle of Shenzhen: From Localizing the Global to Globalizing the Local
Authors: Feng Lihui 
Published: December 2023

AbstractThe phenomenal rise of Shenzhen, a newly emergent city where the number of non-registered residents far exceeds that of registered ones, has been closely associated with a complex and dynamic interplay between the process of globalization, which has enabled Shenzhen’s incredible transformation from an impoverished fishing village to a leading global metropolis, and the forces of localization, which have compelled Shenzhen to take its own distinct circumstances into consideration. The miracle of Shenzhen can be construed not only as an iconic embodiment of China’s process of modernization and globalization since reform and opening-up, but also as a local attempt to reconstruct an alternative modernity with Chinese characteristics in the homogenizing context of globalization. To elucidate how Shenzhen has played a leading role both in promoting China’s integration into the global system and in demonstrating the uniqueness of China’s development in the age of globalization, this article makes a careful exploration of Shenzhen’s process of modern centralization and postmodern decentralization over the past several decades. While modernizing and centralizing itself in the global context, Shenzhen also tries to reconstruct an alternative modernity with concrete Chinese practices, which has not only led to the emergence of multiple centers in China but also undermined the singular and fixed meaning of global modernity by deterritorializing its narrow domain and expanding its restricted reference with specific Chinese practices.
System Relevance and Firm Performance Due to COVID-19
Authors: Böhm Michael J. , Qendrai Pamela 
Published: December 2023

Abstract
We study the impact of COVID-19 on firm performance. Using financial accounts of a large number of German firms, we document that industry affiliation is an important economic dimension of the crisis. Motivated by this fact, we analyze an important industry-specific regulation, system relevance, which allows businesses to remain open in times of lockdown and other restrictions. A difference-in-differences estimation strategy shows that relative revenues of system-relevant firms increase by 6–9 percent and profits by 17–25 percent due to COVID. Controlling for channels that are arguably not driven by the system-relevance regulation, the impact on revenues decreases but remains significant. Overall, results indicate that regulations affecting the ability to operate as well as industry-level shocks play important roles for firm performance during a pandemic-induced crisis.

Published: December 2023

Abstract
Previous studies have shown that microRNAs (miRNAs) are involved in the regulation of a variety of metabolic diseases, which related to some important signal pathways. Our aim was to explore the possible mechanism of miRNAs by revealing the differential expression of serum miRNAs in different BMI of type 2 diabetes mellitus (T2DM) patients with non-alcoholic fatty liver disease (NAFLD). We found that miR-29 decreased liver aminotransferase gamma-GGT and uric acid levels by inhibiting the expression of JNK-1 in non-obese T2DM patients with NAFLD, and down-regulated the expression of atherosclerosis-related factor lipoprotein phospholipase A2 (Lp-PLA2). Combined with bioinformatics analysis, we speculate that this may be mediated by the AMPK signaling. These findings suggest that miR-29 may be a potential targeted therapeutic strategy in T2DM patients with NAFLD.

Authors: Gao Xiang , Jiang Wenqu , Zhu Guofeng , Xing Zelong , Zhu Pengbo , Ke Zunliang , Huang Qiwei 
Published: December 2023

Abstract

Background
Glioma is a kind of nervous system cancer with a low overall survival rate. Aquaporin 1 (AQP1) is linked to a number of cancers. Its prognostic relevance and immunological consequences in gliomas, however, are unclear.

Objectives
Our objective was to thoroughly examine the modified expression of AQP1, its prognostic significance, and its correlation with immune cells and markers to discover innovative molecular immunotherapy strategies for glioma patients.

Methods
RNA sequencing data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases were used. In addition, we used real-time reverse transcription polymerase chain reaction (RT-PCR) and Western Blot methods to monitor AQP1 expression in glioma tissues.

Results
AQP1 expression was greater in gliomas than in traumatized brain tissues. The increased AQP1 expression in gliomas was additionally confirmed through immunohistochemical analysis in the Human Protein Atlas (HPA) repository. An elevated level of AQP1 expression was identified as a separate determinant of the overall survival (OS) and prognosis of individuals with glioma. AQP1 expression was shown to be tightly linked to the tumor immune milieu, immune checkpoint blockade (ICB) and temozolomide drug reaction. In conclusion, the 50 genes that show coexpression with AQP1 indicate that the predominant functions and pathways are related to anterior pattern specification, pattern specification, regionalization, high-density lipoprotein particles, protein–lipid complexes, glycosaminoglycan binding, DNA-binding transcription repressor specific activation to RNA polymerase II, DNA-binding transcription repressor activity, nitrogen metabolism, alpha-linolenic acid metabolism, and fat digestion and absorption.

Conclusions
The results indicate that AQP1 could serve as both a predictive marker and a potential treatment target in glioma.
Heat transfer performance of magnetohydrodynamic multiphase nanofluid flow of Cu–Al2O3/H2O over a stretching cylinder
Authors: Alshehry Azzh Saad , Yasmin Humaira , Ganie Abdul Hamid , Shah Rasool 
Published: December 2023

Abstract
This study examines the heat transfer properties of a recently created hybrid nanofluid in contrast to a traditional nanofluid. The aim is to improve the transfer of heat in the flow of the boundary layer by employing this novel hybrid nanofluid. Our study investigates the impact of the Lorentz force on a three-dimensional stretched surface. We utilize a new model that incorporates thermo-physical factors. A quantitative parametric study is performed to investigate the influence of different physical parameters, enabling meaningful comparisons. The results demonstrate that the hybrid nanofluid exhibits a higher heat transfer rate compared to the conventional fluid, even in the presence of a magnetic field. Moreover, the efficiency of heat transfer can be enhanced by modifying the concentration of nanoparticles in the hybrid nanofluid.
A homotopy perturbation method with Elzaki transformation for solving the fractional Biswas–Milovic model
Authors: Alshehry Azzh Saad , Yasmin Humaira , Shah Rasool 
Published: December 2023

AbstractIn this research, we use the homotopy perturbation method (HPM) combined with the Elzaki transform to investigate the fractional Biswas–Milovic equation (BME) within the framework of the Caputo operator. The fractional BME is a significant mathematical model with applications in various scientific and engineering fields, including physics, biology, and chemistry. However, its fractional nature introduces analytical complexities. By integrating the HPM with the Elzaki transform, we aim to provide an effective approach for obtaining accurate solutions to this equation. The combination of these mathematical techniques allows us to explore the behavior of the fractional BME in a comprehensive manner. The research outcomes are supported by numerical results and comparisons, demonstrating the reliability and efficiency of the proposed methodology. This study contributes to advancing the tools for solving fractional equations and enhances our understanding of the intricate dynamics described by the fractional BME.
The value of plasma metanephrine measurements during adrenal vein sampling
Authors: Carroll Richard W , Corley Brian , Feltham Joe , Whitfield Patricia , Park William , Howard Rowena , Yssel Melissa , Phillips Ian , Harper Simon , Yang Jun 
Published: December 2023

Objective
The assessment of primary aldosteronism incorporates adrenal vein sampling (AVS) to lateralize aldosterone excess. Current adrenal vein sampling protocols rely on concurrent cortisol measurements to assess successful cannulation and lateralization and may be inaccurate in the setting of autonomous cortisol secretion. We aimed to compare the measurement of plasma cortisol and metanephrine concentrations to assess cannulation and lateralization during AVS.

Design
This is a diagnostic accuracy study in a tertiary referral endocrinology department.

Methods
Forty-one consecutive patients with confirmed primary aldosteronism undergoing AVS (49 procedures) were included. None had cortisol autonomy. The use of plasma metanephrine-based ratios were compared with standard cortisol-based ratios to assess cannulation and lateralization during ACTH-stimulated AVS.

Results
There was strong agreement between a cortisol selectivity index (SI) ≥5.0 and an adrenal vein (AV) to peripheral vein (PV) plasma metanephrine ratio (AVmet–PVmet) of ≥12.0 to indicate successful cannulation of the AV (n = 117, sensitivity 98%, specificity 89%, positive predictive value (PPV) 95%, negative predictive value (NPV) 94%). There was strong agreement between the standard cortisol-based SI and an AV plasma metanephrine-to-normetanephrine ratio (AVmet–AVnormet) of ≥2.0 to indicate successful cannulation (n = 117, sensitivity 93%, specificity 86%, PPV 94%, NPV 84%). There was strong agreement between the cortisol- or metanephrine-derived lateralization index (LI) > 4.0 for determining lateralization (n = 26, sensitivity 100%, specificity 94.1%, PPV 91.6%, NPV 100%).

Conclusions
Ratios incorporating plasma metanephrines provide comparable outcomes to standard cortisol-based measurements for interpretation of AVS. Further studies are required to assess the use of metanephrine-derived ratios in the context of confirmed cortisol autonomy.

Significance statement
Primary aldosteronism is a common cause of secondary hypertension, and adrenal vein sampling remains the gold standard test to assess lateralization. Cortisol-derived ratios to assess cannulation and lateralization may be affected by concurrent cortisol dysfunction, which is not uncommon in the context of primary aldosteronism. Our study showed comparable outcomes when using accepted cortisol-derived or metanephrine-derived ratios to determine cannulation and lateralization during adrenal vein sampling. Further research is required to validate these findings and to assess the use of metanephrine-derived ratios in the context of confirmed concurrent cortisol dysfunction.
