AbstractIn the present study, electrospinning of polyvinylpyrrolidone (PVP) and polydiacetylene (PDA) with pomegranate peel (PG) extract was investigated for the preparation of smart and antibacterial nanofibers. Briefly, PDA-PVP solutions were firstly prepared at two different ratios and electrospun under different conditions. Based on the SEM results, the 1:3 ratio of PDA:PVP nanofibers, with an average fiber diameter of 130 ± 40 nm, electrospun at a voltage of 15 kV, feeding rate of 0.5 ml/h and collector distance of 15 cm was selected as the optimal conditions. The addition of PG resulted in an increase in the diameter of the fibers. The color of the electrospun fibers was altered from blue to red due to changes in either temperature or pH or exposure to different solvents. The antibacterial test showed high antimicrobial activity of the fibers loaded with PG extract against both S. aureus and E. coli. MTT assay and cell attachment also validated the biocompatibility of the fabricated nanofibers. Thus, the prepared smart PG-loaded nanofibers had a high potential to be used in wound dressing applications.Keywords: Polydiacetylenepolyvinylpyrrolidonepomegranate peel extractelectrospun nanofiberswound dressing Disclosure statementNo potential conflict of interest was reported by the author(s).

AbstractLife prediction of the parachute canopy is an important consideration before multiple parachute jumps which can prevent unnecessary catastrophic scenarios for skydivers. The present research emphasized the prediction of the life as well as the reliability of the C-9 parachute canopy using a scale-down approach and mathematical modeling. In the research, a rectangular form of small stitched specimens was prepared from ripstop and plain-woven parachute canopy fabric where the seam angle was kept at 45°. Initially, the specimens were subjected to 5, 10, 15, 20, and 25 cycles of tensile impact force considering the critical situation of the C-9 parachute, and subsequently strength loss data was noted. In the results, it was found that, unlike plain-woven, the ripstop fabric specimen increased in strength and work of rupture up to 10 impact load cycles before dropping. Meanwhile, the breaking elongation decreases for both fabric specimens with the impact load cycles. Furthermore, the strength-loss data was extrapolated to assess the life of specimen and thereafter Weibull distribution was used determine the reliability of the specimen. Reliability results indicate that the plain-woven fabric is less reliable, has a faster rate of degradation, and will have a shorter service life than the ripstop fabric. The research revealed that the life of the parachute canopy is expected to be two times more in ripstop than in plain-woven fabric and hence the ripstop canopies may be preferred over plain-woven fabric for long-run applications.Keywords: Parachute canopytensile impact loadwork of rupturedegradationWeibull distribution Disclosure statementNo potential conflict of interest was reported by the authors.

AbstractThe burning and melting of elastic fastening bands in high-temperature environments are major contributors to empyrosis and ambustion owing to their snug fit to human body parts in practical usage. Conventionally fabricated fastening bands show poor degradation, negative environmental impact, and poor flame-retardant performance. Herein, we report an ecofriendly cyclic phosphate ester-based flame-retardant polylactic acid (PLA) elastic band prepared using an impregnation-baking process, and experimental investigation was conducted on the optimized finishing process. The band was characterized using scanning electron microscopy, energy-dispersive spectroscopy, and thermogravimetry. The band exhibited a damage length of 3.9 cm after vertical combustion and self-extinguishing effect after being removed from the fire source without generating molten droplets. The cross-linking phenomenon between the modified PLA fibers was beneficial in improving the flame retardancy of the PLA elastic band in the condensed phase. The strength loss of the band was <5%. Thus, the prepared band can be widely used in real-world applications.Keywords: Antidrippingbakingblast dryercross-linkinggraphitizationorganophosphorus Disclosure statementThe authors report there are no competing interests to declare.Additional informationFundingThis work was supported by the National Key Research and Development Program of China under Grant number 2019YFA0706900 and Jiangsu Provincial Policy Guidance Programme-International Cooperation Projects under Grant number BZ2020010.

AbstractDecamethyl cyclopentasiloxane (D5) was devoted to the medium in the dyeing process of gardenia yellow on cotton fabric to improve the dyeing properties. The effects of D5 percentages and mordants, dyes dosage as well as dyeing temperature and time on dyeing properties were investigated. The results show that optimal dyeing processes of gardenia yellow on cotton in a siloxane-based medium are as follows: D5 percentages 94%vol, dye dosage 2% (o.w.f), alum as mordant dosage 3% (o.w.f), dyeing temperature 80 °C, dyeing time 40 min. Compared with water dyeing, cotton fabrics dyeing with D5/water present enhanced color strength (K/S value) and fine levelness. By fitting the dyeing curves, it is found that dyeing mechanism of gardenia yellow on cotton in D5 follows a pseudo-second-order kinetics model, which is alike to the dyeing kinetics in water. Owing to the hatred of D5, gardenia yellow is rapidly absorbed on the cotton fiber in initial dyeing process, then diffuses and reacts with cotton, which is drived by the diffusive force inducing by the concentration differences of dyes between dye liquor and fiber. In addition, the color fastness of cotton fabrics dyeing with D5/water is equal to that dyeing with water. This dyeing technique that immensely reduces dyeing wastewater has potential application in natural dyestuffs.Keywords: Gardenia yellowD5dyeing kineticscolor strengthcolor fastness AcknowledgmentsThe authors are grateful for the financial support provided by Fujian External Cooperation project of Natural Science Foundation (No. 2022I0042), Fujian Young and Middle-aged Teachers Education research project (No. JT180376), and Quanzhou City Science & Technology Program of China (No. 2019C014R).Disclosure statementNo potential conflict of interest was reported by the authors.

AbstractThis paper aims to study the hygroscopic exothermic behavior of fabrics, exploring the feasibility of achieving much slower and more even hygroscopic heating process by strengthened moisture transmission control. Based on the model of coupled heat and moisture transfer, the moisture diffused-transmission, ‘type-ladder’ mechanism was proposed, and then different moisture-absorbing and heating knitted fabrics were prepared by dissimilar finishing. The result showed that the mechanism of ‘type-ladder’ had the feasibility and advantages in retarding, extending and uniforming the moisture absorption and heat generation. Moreover, it was found that the inner layer of the composite finishing fabric was much more sensitive to the moisture with a faster diffusion and a closer water-fiber interaction through the analysis of the moisture transmission. By means of finishing to obtain the variation both in moisture state and diffusion, caused the fabric heating up much slowly in the continuous high-humidity micro-environment and evenly in the micro-environment with the moisture increasing until high-humidity significantly, which is further proven by the heat of desorption. These results demonstrated that hygroscopic exothermic fabric on ‘type-ladder’ mechanism might provide a new option fit to the actual thermal and humid comfort requirements.Keywords: Hygroscopic exothermic fabric‘type-ladder’ diffused-transmission mechanismuniform and slow moisture absorption and heat generationcoupled heat and moisture transfer Disclosure statementNo potential conflict of interest was reported by the authors.Table 1.

AbstractAlmost, spent coffee grounds are discarded to landfill, causing bad impacts on natural environment and generating a great waste because of removing beneficial bioactive compounds. This study investigated effects of dyeing techniques (exhaustion and pad-dry), types of mordants, sequences of adding mordants, temperature, exhausting time and concentration on dyeability of coffee extracts for cotton fabric in terms of color strength (K/S) and color difference (ΔE), thereby proposing a suitable treatment procedure. The experimental results showed that K/S and ΔE values were highest when mordanting with FeSO4.7H2O and CuSO4.5H2O. Simultaneously, highly antioxidant and antibacterial properties of treated cotton were quantitatively evaluated by UV-vis spectroscopy, scanning electronic microscopy, microbiologicalmethod and mechanical experiments. The content of polyphenols and tannins as well as the bacteriostatic activity of gram-positive and gram-negative species on treated cotton fabrics with coffee extracts were promising in future applications. Particularly, the total amounts of polyphenols and tannins, which could demonstrate antioxidant activity, were examined as 3.01 g/L (GAE) and 0.57 g/L (TAE), respectively. Especially, high reduction of E. coli bacteria and S. aureus bacteria on dyed specimens accounted for 78% and 80% as mordanting with CuSO4.5H2O, and it could be sustained to 75% and 48% after a washing cycle, respectively.Keywords: Antioxidant abilityantibacterial activityspent coffee groundsdyeabilitymordanting method AcknowledgementsThe authors would like to thank for support from Faculty of Mechanical Engineering at Ho Chi Minh City University of TechnologyDisclosure statementWe all commit that there are no conflicts of interest among authors as well as others and this manuscript has not been published to other journals before.Additional informationFundingThis work belongs to the project grant No: T2022-73 funded by Ho Chi Minh City University of Technology and Education, Vietnam.

AbstractSilver nanocomposites (Ag-NPs/PVP) were synthesized through the reduction of Ag+ using Ethylene glycol (EG) and poly(N-vinylpyrrolidone) (PVP) as a protective agent in an alkaline medium. Characterization involved UV–Vis spectrum, and TEM image, confirming the well spread of the nanoparticles with a particle size of range 5–10 nm. Stability, assessed after three months, revealed a zeta potentialof −17 mV, identicating no agglomeration. . PVP role in decreasing the nanoparticle size was studied, attributed to the protective layer preventing aggregation. . The study enhanced the antibacterial activity of various cellulosic fabrics (cotton, linen, and viscose) by activating their surfaces through O2 plasma pretreatment at atmospheric pressure.

AbstractThis study aims to develop a consumer typology based on the importance of product attributes in consumer face mask consumption during the COVID-19 pandemic. An online survey with a MaxDiff experiment was employed to measure the importance of eight face mask attributes. Data were collected from 563 U.S. consumers during April 2022. Hierarchical Bayes analysis, K-means clustering, Chi-square tests, and ANOVA were used for data analysis. Results suggested that protection and comfort were the most important attributes, while appearance and brand were the least important. Based on the tradeoffs made in their purchase decision-making process, three distinct groups of face mask consumers were identified, named protection-focused, utilitarian-driven, and eco-conscious consumers. A consumer profile was established for each group, reflecting their mask-wearing behaviors, mask type preferences, and demographics. This study provides implications for face mask manufacturers and retailers to develop effective production and target marketing strategies for future respiratory pandemics.Keywords: Face maskattribute importanceMaxDiffcluster analysismarket segmentation Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author upon reasonable request.Permission to reproduce material from other sourcesThere are no excerpts from copyrighted works owned by third parties included in this study.Additional informationFundingThis work was supported by a grant from the NSRP program at North Carolina State University.

This study provides implications for face mask manufacturers and retailers to develop effective production and target marketing strategies for future respiratory pandemics.Keywords: Face maskattribute importanceMaxDiffcluster analysismarket segmentation Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author upon reasonable request.Permission to reproduce material from other sourcesThere are no excerpts from copyrighted works owned by third parties included in this study.Additional informationFundingThis work was supported by a grant from the NSRP program at North Carolina State University.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141186","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}

AbstractBy adjusting n(Na2O)/n(SiO2) and crystallization time, zeolite A - basalt fiber composite was successfully prepared by direct loading method under the system composition of n(SiO2)/n(Al2O3)=2, n(H2O)/n(SiO2)=125, n(Na2O)/n(SiO2)=2.1. The samples were determined by XRD, SEM, FTIR and calcium ion exchange. The results show that the composite of fiber and zeolite A is a combination of structure, and the crystallization time will affect the morphology of zeolite and composite effect. After crystallization for 6h, zeolite A with high crystallinity and moderate particle size can be obtained. At the same time, the loading ratio of zeolite on the fiber surface reaches the maximum, but the alkaline environment will reduce the fiber strength.Keywords: zeolite Abasalt fiberzeolite A- basalt fiber compositeion exchange Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was financially supported by the Fund from the Innovation Capacity Grant Project for Master Degree Candidate in Hebei province (CXZZSS2022019), the science and technology project of Hebei Education Department (BJK2023040), and the Central Government Guide Local for Scientific and Technological Development (206Z1501G).

AbstractEffect of carbon nanotubes (CNTs) on the dielectric properties of spandex fabric is studied theoretically. The frequency and CNTs dependence of the real and imaginary part of the complex dielectric permittivity are calculated and compared with experimental results of spandex fabric. An appreciable change in the dielectric permittivity has been observed for CNTs doped spandex fabric. Good agreement between theoretical and experimental results is observed.Keywords: Textilespandex fabricdielectric permittivitydielectric losscarbon nanotubes Disclosure statementThe authors declare no conflict of interest, financial or otherwise.
