Their application in antibacterial modification of sportswear fabric was then explored. The structure and properties of L-AgNPs were characterized by ultraviolet–visible spectroscopy (UV–Vis), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). L-AgNPs at different concentrations were loaded onto fabrics, and artificial sweat was used to simulate different exercise intensities. Results indicated that L-AgNP-treated fabrics inhibited <i>E. coli</i> proliferation at varying sweat concentrations, as confirmed by antibacterial zone tests and <i>E. coli</i> growth curve analyses. Under simulated high-intensity exercise conditions, the antibacterial rate remains stable at over 85.8% even at the optimal modification concentration of 40 mg/mL. This study clarified the relationship between the structure of L-AgNPs and antibacterial activity and identified the antibacterial conditions in sports scenarios. This study only selected <i>E. coli</i> as the model bacteria and tested only polyester-cotton-blended sportswear fabric. It is hoped that future research will expand the types of bacteria, increase the variety of fabrics, and improve experimental studies on washability and leaching behavior evaluation. These findings provide a green, feasible modification strategy for developing durable antibacterial sportswear fabrics adaptable to different exercise intensity sweat environments.</p><h3>Graphic 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":"27 9","pages":"4295 - 4304"},"PeriodicalIF":3.1,"publicationDate":"2026-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695617","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, a series of quaternized epoxidezed glycidyl ether-modified polyurethane fixing agents with quaternary ammonium cation and multiple hydroxyl groups were synthesized by adjusting the molar ratio of glycidyl ether (AGE) to polyurethane terminal agent hydroxyethyl acrylate (HEA).

Chemical-free dyeing has also become a sustainable alternative to conventional dyeing that avoids using chemicals. This study investigates the use of <i>Khaya anthotheca</i> bark, known for its high tannin content, for dyeing 100% cotton fabrics, as dyestuff containing tannin effectively binds with fibers to provide color fixation without using mordants. The cotton fabrics were dyed using the aqueous extract in the exhaust method at 90 °C for 60 min. The colorimetric attributes of the dyed samples, specifically color strength (<i>K/S</i>), and color variations were assessed using a spectrophotometer. The increase in <i>K/S</i> values from 1.1 at a 1:20 m:L ratio to 1.7 at a 1:50 m:L ratio demonstrates enhanced color depth as liquor volume increases. The color difference value (Δ<i>E</i>*) increased from 24.71 to 28.99, which also indicates a perceptible enhancement in color. FTIR spectroscopy suggested the presence of tannin in the dyed fabric, as there has been a shift of peak from 3305 cm⁻¹ to 3301 cm⁻¹, representing the O–H stretching. The color fastness test against wash and perspiration demonstrated a very good to excellent rating. Moreover, the antimicrobial efficacy of dyed fabric was evaluated, and the dyed fabric demonstrated a 97.4% reduction in bacterial count compared to the undyed samples.

Afterward, exhaustion foam dyeing was studied by varying the temperature, dyeing time, sodium sulfate content, and drum rotation until the optimal conditions for this new process were determined. The process was optimized using a full-factorial design approach, and the optimized foam dyeing conditions were as follows: bath temperature: 65 °C, dyeing time: 30 min, sodium sulfate concentration: 20 g/L and drum rotation speed: 40 rpm. The effectiveness of the process was measured through color strength and evaluated for washing, rubbing, and lightfastness. A comparative analysis between foam dyeing and conventional dyeing methods was also conducted. The results revealed that this process saved 55.97% and 52.30% of water and energy consumption costs, respectively. These savings are considered highly significant, offering a valuable opportunity to reduce water and energy costs at an industrial scale. Reducing water usage also directly decreases wastewater generation, thereby minimizing the ecological footprint of textile finishing operations. In addition to reducing wastewater generation, this reduction is expected to lower wastewater treatment costs by approximately 50%. Coupled with lower energy demand, this method supports global efforts to conserve natural resources, reduce pollution, and advance sustainable manufacturing practices.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"27 9","pages":"4407 - 4421"},"PeriodicalIF":3.1,"publicationDate":"2026-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695587","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}

The reduction peak potential of these organic sources is measured at specific time intervals over 18 days at room temperature using the saturated calomel electrode (SCE) as the reference electrode. In the present study, silk is dyed with indigo in the presence of organic reducing agents, as specified, and chemical reducers, such as sodium dithionite, at room temperature. However, from practical experience and previous reported work, it is observed that artisans sometimes use higher reduction temperatures (60–70 °C) to achieve a good shade depth when tamarind is used as a reducing agent during indigo dyeing. Hence, in this study, indigo does not produce good shade depth on silk when dyed at room temperature in the presence of tamarind as a reducing agent. The reported findings of the present study apply to room-temperature vats under the tested conditions. Among these reducing agents used in the study, &lt;i&gt;cassia tora&lt;/i&gt; and madder maintain negative reduction peak potentials throughout the 18-day period. However, as the day progresses, their reducing power decreases. The same trend is observed for other reducing agents, but they do not maintain a negative reduction peak potential up to 18 days, thus, gradually losing the reducing power. The decrease in reducing power results in less conversion of leuco-indigo salt from its insoluble state, ultimately resulting in lower shade depth. The UV–visible absorption spectrum of indigo dye exhibits maxima at 286 and 603 nm, indicating an extensive conjugated system. The blue colour and absorption spectrum of indigo may be due to electronic transitions in the conjugated π-electron systems in the chromophore groups when exposed to light. Fourier transform infrared spectroscopy reveals the presence of various functional groups and bioactive compounds, including saponins and tannins, in the dye. Silk fabric treated with &lt;i&gt;cassia tora&lt;/i&gt; seed and madder shows no fungal growth (average rating: 0). In the antibacterial assessment, silk fabric, when treated with &lt;i&gt;cassia tora&lt;/i&gt; seeds, shows a 99.7% reduction of microorganisms against both &lt;i&gt;S. aureus&lt;/i&gt; and &lt;i&gt;K. pneumoniae&lt;/i&gt;, whereas madder shows 99.02 and 99% reductions in gram-positive and gram-negative bacteria, respectively.
