Body odorants typically transfer to clothing fabrics by way of liquid sweat, yet investigations of odor retention in textiles often neglect this route of exposure in their test procedures. This paper describes a novel method for transferring selected odorous volatile organic compounds to six types of textile fibers in yarn bundle form by an aqueous sweat solution. Headspace volatile organic compounds varying by chemical class (ketones, aldehydes, carboxylic acids) were monitored at discrete time intervals (30 min, 3 h, 24 h) using proton transfer reaction mass spectrometry. Lower intensities of ketones and aldehydes were detected in the headspace above cellulosic fibers (cotton, mercerized cotton, viscose) than above wool, nylon, and polyester fibers at 30 min. A rapid decrease in ketones occurred for all fibers, but lower intensities of ketones were released after 3 h for cellulosic and wool fibers. Nylon fibers typically released the highest amounts of ketones and aldehydes at 30 min, but by 24 h higher intensities of these compounds were released from polyester. Carboxylic acids exhibited minimal differences in intensities between 30 min and 3 h, with few differences evident among fiber types. Understanding the preferential sorption of odorants when clothing is exposed to volatile organic compounds in aqueous solutions such as sweat is enhanced from the results of this investigation.

In many processes and applications, the performance of textiles relies heavily on fluid transport; for example, the in-plane distribution of water and the through-plane permeation of water vapor and air. Prediction of knitted fabrics’ effective transport characteristics can enhance development workflows and bring them to new applications. Effective transport parameters that are particularly important are the permeability and diffusive mass transfer. Usually, experiments are used to determine these parameters. It is desirable to conduct a thorough investigation into how yarn structure and knitting gauge influence these properties to tailor knitted fabrics for a particular application. Our contribution in this context describes a consistent workflow to forecast the effective mass transfer characteristics of single jersey fabrics. Single jersey fabrics have been chosen for they are the simplest patterning, and are widely used in body-near worn garments. The proposed approach involves visualizing fabric samples with a light microscope, and subsequently determining relevant geometric parameters through automated image processing algorithms. With these parameters in hand, a representative elementary volume of the fabric is constructed. The yarn is modeled as an effective medium to reduce calculation time. The representative elementary volume is then used for numerical predictions of air permeability and the diffusive water vapor transport. The predicted through-plane gas transport properties are compared with experimental data to validate the approach. Six different single jersey polyester fabrics were analyzed, with different yarn structures and machine gauges. The comparison shows a good agreement between simulated and measured transport properties.

In accordance with the tenets of displacement deviation theory, the distribution of accelerating positions was the main reason for the uneven output sliver. To elucidate this phenomenon, a dynamic drafting model with controllable fiber proportion was developed in this paper to simulate the accelerating process of the floating fiber. The model was employed to investigate the impact of the friction field on the distribution of accelerating positions, achieved through the manipulation of friction field distribution and fiber proportion in the drafting zone. The simulation results indicated that, with various drafting conditions, the friction field at the position with a higher slow fiber proportion always made the accelerating position distribution closer to the front roller. In addition, the duration of the friction field influence on the fiber floating process was found to be directly proportional to its effect on the accelerating position distribution. Furthermore, there was a critical slow fiber proportion, which increased in tandem with the augmentation of slow fiber proportions in the drafting zone. The friction field at the position where the proportion of slow fibers was higher than the critical slow fiber proportion made the accelerating position distribution closer to the front roller; otherwise, the friction field made the accelerating position distribution closer to the back roller. This study can offer a valuable reference for designing more effective friction field distribution to improve the output sliver quality.

The ginning process has an effect on fiber quality. Avoiding fiber quality deterioration due to mistune or overspeed is crucial, especially in west and central Africa where value chains are highly dependent on prices paid for premium fiber quality. Indeed, fiber classification alone does not permit a reliable measurement of ginning impact, as it depends on many factors such as incoming seed cotton quality, equipment type, number, and settings within each ginning process stage. This study describes a sampling and analysis method precise enough to detect any commercial impact on fiber quality at each main ginning stage. It is based on fiber quality characteristic measurements before and after each main stage: seed cotton cleaning, ginning, and lint cleaning. The sampling and testing protocol was applied in Mali in seven industrial gins during the 2015–2016 ginning season. Seed cotton samples were taken before and after the seed cotton cleaning stage, and fiber samples before and after the lint cleaning stage. Seed cotton samples were ginned with a reference saw micro-gin. The precision of fiber characterization was measured by replicating twice each fiber sample characterization in a laboratory meeting the international standards. Based on the variability measured in Mali, we determined for each fiber characteristic the number of replicates required to detect any commercially harmful impact. Growing and ginning conditions in Mali are representative of those in west and central Africa. Based on this method, one needs to develop an on-line tool to measure fiber quality at every stage of industrial ginning.

The escalating incidence of Candida spp. infections among individuals with compromised immune systems is attributed to various factors, including broad-spectrum antibiotic usage, common health issues, and inadequate undergarments, requiring novel preventive measures. While the pathogenic mechanisms of Candida spp. infections remain incompletely understood, their virulence attributes and opportunistic nature challenge host defenses. In response, this research study introduces an innovative nanobiotechnological approach employing L-cysteine to develop nontoxic anti- Candida spp. textile materials. Cotton, an ideal material for women’s underwear, was functionalized with L-cysteine through an exhaustion procedure following activation with 2,2,6,6-tetramethylpiperidinyl-1-oxy free radical. The results demonstrated increased energy dispersive X-ray peaks corresponding to sulfur atoms in the functionalized cotton fabric, confirming that L-cysteine remained attached to the cotton surface even after washing cycles. Moreover, the cotton containing L-cysteine displayed morphology and mechanical properties similar to the nonfunctionalized cotton, indicating that the incorporation of L-cysteine did not impact the cotton properties. In addition, cotton functionalized with L-cysteine exhibited a significant reduction in yeast growth – 87.04 ± 1.90% for Candida albicans and 65.28 ± 3.03% for Candida parapsilosis – highlighting its potential as a class I medical device, particularly for preventing candidiasis in women’s medical underwear.

Nurses often encounter negative emotions such as fatigue, boredom, anxiety and fear in the course of their nursing duties, and one of the efficient approaches to improve their emotions is to wear the proper nursing scrubs during their tasks. This paper presents a work with the overall objective to have an emotionally tailored apparel design of nursing scrubs. To reach this objective, the study first mines Kansei words to recognize nurses’ emotions in nursing scrubs domain. Then, design attributes and their corresponding attribute levels for nursing scrubs are identified and determined by applying the rank sum ratio method. Furthermore, a model mapping nurses’ emotions to design attributes of nursing scrubs is established by employing the entropy-weight technique for order preference by similarity to an ideal solution approach. The study yields two significant contributions: (a) presenting the first ever emotion recognition for nurses, which provides a domain-specific foundation for investigating nurses’ psychological wellbeing; (b) constructing a model to conduct the emotional apparel design of female nursing scrubs, which offers a guide to improve preferred and satisfied female nursing scrubs for nurses, and thus positive emotions will be experienced during their nursing duties.

The excellent load-bearing performance of sized warp yarns can reduce the end-breakage rate and enable them to complete weaving smoothly. Evaluating the load-bearing performance of sized warp yarn can guide the sizing process and weaving production. For this purpose, the study evaluated the load-bearing performance of cotton sized warp yarn. First, based on the JN-01 tester, a weaving load simulation tester of sized warp yarn, the test sample capacity for the load-bearing life was determined to be 50 ends using a U-test. Second, by testing three cotton sized warp yarns with different linear densities, the universality of the parameter conditions of the tester was verified. Third, with the JN-01 tester, the breaking strength and hairiness under different load-bearing cycles were measured, and it was found that the breaking strength of the sized yarn was linearly related to the load-bearing cycles. In contrast, the hairiness of the sized yarn was logarithmically related to the load-bearing cycles. According to regression analyses, evaluation indicators were extracted to characterize the strength loss resistance and anti-fuzzing performance of sized warp yarns, which were the residual enhancement rate and hairiness after friction. The evaluation results of sized warp yarns, with different linear densities and different sizing ratios, showed the effectiveness of the evaluation indicators. Finally, by verifying the effectiveness of samples from three factories, based on the evaluation indicators in this paper, the results revealed that the constructed evaluation method effectively evaluated the load-bearing performance of cotton sized warp yarn.

Textiles, serving as a second skin for the human body, play a significant role in regulating the microenvironment temperature, and enhancing thermal comfort of the human body during cold weather. However, the most current methods for enhancing the warmth of fabrics involve complex chemical treatment or the application of advanced materials, thus suffering from potential chemical toxicity (especially for infants), complex processing and high cost. Herein, we report a simple strategy for directly processing cotton roving into environmentally friendly and structurally stable thermal-retention cotton textiles by means of hierarchically self-locking structures. The textile not only shows excellent heat-retention properties and mechanical firmness compared with conventional thermal insulation wadding and certain commercial blankets, but is also environmentally friendly and cost effective. This method may provide a new generation of thermal insulation materials with enhanced health and environmental benefits based on hierarchical structure design and natural textile materials.

The rapid development of piezoelectric sensors has been studied extensively, owing to their good flexibility, wearability, high sensitivity and low cost. However, some inorganic materials with good piezoelectricity cannot make sensors flexible, and the organic materials with good flexibility have a weak output electrical signal and low strength. In order to explore and optimize the preparation technology of piezoelectric sensors, a BaTiO3@polyacrylonitrile (PAN)/poly(vinylidene fluoride) (PVDF) nanofibrous composite membrane (NCM) was prepared by cross-electrospinning technology and the central combination design (CCD) method. The morphology, structure, hydrophobicity, mechanical properties and piezoelectricity of the BaTiO3@PAN/PVDF NCMs were investigated. The BaTiO3@PAN/PVDF NCMs had the better hydrophobicity and mechanical properties compared with the pure PAN/PVDF NCM. The 5BaTiO3@PAN/PVDF NCM designed by CCD had a more uniform fiber diameter, and a more stable output voltage with a 46% improvement. With the help of cross-electrospinning technology and the CCD method, the NCM will be outstanding for the development of fabricating flexible wearable piezoelectric sensors.

In order to explore and optimize the preparation technology of piezoelectric sensors, a BaTiO<jats:sub>3</jats:sub>@polyacrylonitrile (PAN)/poly(vinylidene fluoride) (PVDF) nanofibrous composite membrane (NCM) was prepared by cross-electrospinning technology and the central combination design (CCD) method. The morphology, structure, hydrophobicity, mechanical properties and piezoelectricity of the BaTiO<jats:sub>3</jats:sub>@PAN/PVDF NCMs were investigated. The BaTiO<jats:sub>3</jats:sub>@PAN/PVDF NCMs had the better hydrophobicity and mechanical properties compared with the pure PAN/PVDF NCM. The 5BaTiO<jats:sub>3</jats:sub>@PAN/PVDF NCM designed by CCD had a more uniform fiber diameter, and a more stable output voltage with a 46% improvement. With the help of cross-electrospinning technology and the CCD method, the NCM will be outstanding for the development of fabricating flexible wearable piezoelectric sensors.","PeriodicalId":22323,"journal":{"name":"Textile Research Journal","volume":"51 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140801172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study antimicrobial linen-cotton jacquard textiles were manufactured using green chemistry methods. The functionalization of the fabrics was executed by impregnating chitosan microencapsulated bio-based oils from angelica ( Angelica archangelica L.) (AAC) and marsh Labrador tea ( Rhododendron tomentosum Harmaja) (MLTC) obtained with pilot scale supercritical carbon dioxide extraction. The chemical compositions of the extracts of angelica and marsh Labrador tea were analyzed by a combination of gas chromatography and mass spectrometry. The antimicrobial activities of the extracts, AAC and MLTC microcapsules, and the microencapsulated textiles (AAC and MLTC textiles) were analyzed against gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria, dimorphic yeast Candida albicans and filamentous mold Aspergillus brasiliensis. The AAC textile proved 40% inhibition against S. aureus, whereas the MLTC textile demonstrated 43.8% and 51.7% inhibition against both S. aureus and E. coli, respectively. Although the chitosan shell material itself indicated mild activity against both bacterial strains, the extracts increased the antibacterial activities in microencapsulated textiles. In addition, the antifungal impact of the MLTC textile was demonstrated against A. brasiliensis. According to the Fourier transform infrared spectroscopy with attenuated total reflection and field emission scanning electron microscopy analyses, covalent bonding between the microcapsules and textile fibers was established with citric acid as a cross-linker. The antimicrobial activity was also shown to persist in the MLTC textiles after six domestic washing cycles.
