However, their application in textiles is often hindered by limitations such as low color yield and poor fastness, which necessitate the use of mordants. This study investigates the effectiveness of a double mordanting technique to enhance the color strength and fastness of curcumin, a natural yellow dye derived from turmeric, on cotton fabrics. The double mordanting process involved the sequential application of waste-derived biomaterials (pomegranate rind, onion peel, and chitosan) and metallic mordants, followed by dyeing with curcumin. The dyed fabrics were comprehensively evaluated based on color parameters, color strength, levelness, and fastness. Results showed that double mordanting led to a significant improvement in both color strength—up to 69.68% higher—and wash fastness—up to 1.5 grades better—compared to traditional single mordanting. Additionally, the process reduced the residual metal content in the mordant bath by up to 27.00%, promoting a more sustainable dyeing method. Various combinations of biomordants and metal mordants were found to produce fabrics with diverse hues and shades. Notably, the combination of pomegranate rind and iron(II) sulfate yielded a rich, deep black shade on cotton. These findings underscore the potential of using waste-derived biomordants in a double mordanting process as an eco-conscious and effective strategy to enhance the performance of curcumin-dyed cotton while minimizing environmental impact.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"26 9","pages":"3963 - 3979"},"PeriodicalIF":2.3,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814329","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, polycarbonate/thermoplastic polyurethane (PC/TPU) nanocomposite membranes were electrospun and incorporated with 1, 3, and 5 wt.% copper oxide nanoparticles (CuO NPs). The resulting membranes were evaluated in terms of their morphological features, chemical composition, hydrophilicity, tensile strength, water flux performance, and anti-fouling capabilities. Morphological analysis revealed that the average diameter of the electrospun nanofibers ranged between 67 and 90 nm. Energy dispersive X-ray spectroscopy (EDS) indicated a tendency for CuO NPs migration and agglomeration at the highest loading of 5 wt.%. Fourier transform infrared spectroscopy (FTIR) confirmed the presence of all characteristic functional groups from the constituent materials in the final nanocomposite membranes. Water contact angle (WCA) measurements demonstrated a significant improvement in membrane hydrophilicity with CuO NP incorporation. Specifically, WCA decreased from 114° for the neat membrane to 63° when the CuO NP content was increased to 3 wt.%. Water flux experiments were carried out using a submerged filtration module with humic acid (HA) as a model organic pollutant. The membrane containing 3 wt.% CuO NPs exhibited a pure water flux of 907 L.m⁻².h⁻¹ and a HA solution flux of 446 L.m⁻².h⁻¹. Furthermore, NFM-Cu3 displayed superior anti-fouling performance with an irreversible fouling ratio (IFR) of only 5.8% and high HA rejection efficiency of about 99%. These findings suggest that ENCMs containing CuO NPs has the potential to serve as an effective alternative to conventional thin-film polymer membranes in water filtration systems, offering improved permeability, selectivity, and fouling resistance.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"26 9","pages":"3871 - 3888"},"PeriodicalIF":2.3,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814271","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}

Two fabrication approaches—spray coating and gravity sedimentation—were employed to construct structural colors on white polyester fabrics. The results demonstrated that Prussian blue dye/SiO₂ composite microspheres (SiO₂@PB) enabled vivid structural coloration on white textiles.

In this study, the influence of aging and UVR on the antibacterial properties and degree of coloration of knitted fabrics was investigated. Knitted fabrics of different raw materials compositions in single weaves made of three types of yarn: cotton (CO), bamboo (BAM), and polyester (PES), were used. Samples were treated with methanol extract of &lt;i&gt;Achillea millefolium&lt;/i&gt; L. conc. 100 mg/mL, to which citric acid and tannic acid were added, using ultrasonic atomization. Using an ultrasonic atomizer increased the speed of dyeing, shortened the processing time and allowed the use of a smaller amount of extract compared to conventional dyeing. The antibacterial properties of knitted fabrics obtained against &lt;i&gt;Staphylococcus aureus&lt;/i&gt; and &lt;i&gt;Escherichia coli&lt;/i&gt; were evaluated. The tests of antibacterial properties and color strenght (&lt;i&gt;K/S&lt;/i&gt;) of knitted fabrics were done after dyeing, after aging (30 months), and after exposure to UV light with a wavelength of 254 nm and 365 nm. The antibacterial effect of knitted fabrics dyed with &lt;i&gt;A. millefolium&lt;/i&gt; L. extract on &lt;i&gt;S. aureus&lt;/i&gt; after natural aging and treatment with UV wavelength of 254 nm results in a reduction of the zone of inhibition (&lt;span&gt;({Z}_{i})&lt;/span&gt;) from 23% (BAM) to 57% (CO), compared to &lt;span&gt;({Z}_{i})&lt;/span&gt; after dyeing. Treatment of the samples with UV light with a wavelength of 365 nm increased the &lt;span&gt;({Z}_{i})&lt;/span&gt; against &lt;i&gt;S. aureus&lt;/i&gt;, in PES knitted fabric was even higher than after dyeing, while there were no significant changes &lt;i&gt;in E. coli&lt;/i&gt;. In CO and BAM knitted fabrics, after aging and exposure to UV radiation, high protection factors (UPF) were found, the values of which ranged from 31.38 to 51.68.

The strategic sequence of treatments promotes adequate TiO₂ adhesion, fiber densification, and improved fiber matrix compatibility. This approach addresses critical limitations in raw jute fiber performance and offers a scalable path forward for bio-based composite development in packaging, textiles, and other industrial applications. Raw jute fibers exhibited low breaking force and high water absorption. TiO₂ coating improved these properties, with further enhancements observed upon gamma irradiation at 3 kGy. The most significant improvements were the chemical treatment to remove lignin and hemicellulose (cellulose JF) and per-acetic acid (PAA) treatment, combined with TiO₂ coating and gamma irradiation. PAA-treated fibers showed the highest breaking force (492.23 N, a 112% increase compared to raw fibers), tensile strength (169.85% increase), elastic modulus (237.26% increase), and toughness (116% increase).

In this paper, new biodegradable terpolymers (BPAN) with starch (ST), chitosan (CS), acrylonitrile (AN), 2-hydroxy ethyl methacrylate (HEMA), and vinyl acetate (VA) have been synthesized with different chemical properties using suspension polymerization initiated by sodium bisulfite/ammonium persulfate. The effect of polymerization conditions, concentration, and types of monomers on the characteristics of BPAN was analyzed. Cultured fungal and Burial test were used to test the biodegradability of a selected BPAN. Biodegradable fiber (BioF) from a BPAN was obtained by wet-spinning and used for the fabrication of geotextiles. The effective use of the geotextiles, on radish plant growth and soil moisture retention, was examined. The results showed that the polymerization system AN-HEMA-ST base provides good polymer conversion rate, high molecular weight, high moisture retention, and high grafting efficiency. The biodegradation of a film from a selected BPAN was observed by changes in coloration and fragmentation of small particles after 150 days of Burial test. Functional group changes from FTIR analysis confirmed the degradation. Fungal growth after 13 days of observation on sprayed BPAN also confirmed biodegradability. In addition, biocompatibility was observed by root growth on the surface of the BPAN film.

Its fiber preparation process is low cost and environmentally friendly. The process of preparing PP yarns involves forming stable fibers, aggregating the fibers into bundles, and twisting the bundles to form yarns. However, in the melt electrostatic spinning process, the poor uniformity of the melt reaching the nozzle position leads to an unstable fiber generation process during spinning, which increases the difficulty of directly and continuously collecting the fibers and forming fiber tows. In this paper, a melt-differential electrostatic spinning method using unilateral airflow assistance is proposed for the preparation of PP fiber tows. In this method, the melt at the nozzle is stretched and cooled to form fibers under the action of an electric field. Assisted by a unilateral airflow, these fibers can be further stretched and cooled before contacting the electrode plate, and are finally collected on a rotating roll to form fiber bundles. In this paper, the effects of voltage, airflow rate, and collection roller speed on the morphology and mechanical properties of fibers and their assemblies are investigated. The experimental results show that the addition of auxiliary airflow significantly improves the collection efficiency of fibers when the speed of unilateral auxiliary airflow is controlled within 2.5 m/s compared with the experimental results without auxiliary airflow, and the number of fibers in each fiber bundle increases under the condition of auxiliary airflow.
