However, its intrinsic hydrophilicity and susceptibility to contamination limits its broader application. In this study, an epoxy resin/silica/polydimethylsiloxane (EP@SiO<sub>2</sub>/PDMS) composite coating was fabricated on the fabric cotton by a simple immersion method, endowing the cotton matrix self-cleaning superhydrophobic property. Silica nanoparticles were combined with a small amount of EP to provide appropriate surface roughness, while the outermost PDMS coating was applied to enhance hydrophobicity. The results showed that the prepared EP@SiO<sub>2</sub>/PDMS-coated cotton fabric achieved an average contact angle of 152.8°, demonstrating excellent self-cleaning property. Thanks to the dual-layer coating structure, the EP@SiO<sub>2</sub>/PDMS-coated cotton fabric exhibited remarkable environmental stability. It maintained its superhydrophobicity even after 60 min of ultrasonic treatment. After 100 abrasion cycles, the contact angle of the fabric remained at 137.9°, indicating strong hydrophobicity. Additionally, the EP@SiO<sub>2</sub>/PDMS-coated cotton fabric demonstrated improved thermal stability and strong chemical stability. The EP@SiO<sub>2</sub>/PDMS-coated cotton fabric retained its superhydrophobicity after being soaked in various organic solvents for 24 h and remained its water contact angles above 148° after being immersed in acidic, alkaline, and salt solutions for 6 h. The superhydrophobic coating developed in this study is robust, durable, environmentally friendly, and simple to be prepared, showing promising potential for applications in the textile industry.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"27 5","pages":"2191 - 2205"},"PeriodicalIF":2.3,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733148","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}

This study presents a modification approach to enhance the comfort performance of dehydrated BC through the incorporation of recycled silk fibroin and electron beam irradiation (EBI). In terms of sensorial comfort, the integration of fibroin gel effectively mitigates the inherent rigidity and brittleness of BC by forming a stable interpenetrating polymer network. This structural modification results in a substantial reduction in bending modulus, from 3478.2 ± 360.2 MPa of pristine BC to 652.7 ± 194.0 MPa of the BC/Fibroin composite, accompanied by an increase in tensile strain from 2.3 ± 0.9 to 5.8 ± 1.6%. Subsequent EBI treatment further optimizes these properties, yielding an EBI-BC/Fibroin composite with a markedly lower bending modulus of 43.6 ± 14.7 MPa and an enhanced tensile strain of 8.8 ± 2.9%. The EBI-induced cross-linking also improves structural integrity, ensuring the stable retention of fibroin gel after rinsing by acetone and resulting in a higher areal density (190.6 ± 33.5 g/m<sup>2</sup>) compared to BC (49.1 ± 0.9 g/m<sup>2</sup>). Furthermore, the synergistic modification (EBI-BC/Fibroin) enhances thermal comfort, as reflected by an elevated <i>Q</i><sub>max</sub> value of 0.237 ± 0.010 W/cm<sup>2</sup>, compared to 0.081 ± 0.005 W/cm<sup>2</sup> of BC.

Their preparation process is cost-effective and environmentally friendly. The fabrication of PP yarns typically involves stable fiber formation, fiber bundling, and twisting of fiber bundles. However, during melt electrospinning, uneven melt distribution at the nozzle tip causes the jet to experience local electric field effects, resulting in instability and increasing the difficulty of continuous fiber collection and bundle formation. To address this challenge, a novel fiber bundling method combining a hollow annular electrode with annular airflow was developed. The axial thrust of the annular airflow and the electric field distribution of the hollow electrode synergistically stabilize the melt jet, thereby promoting continuous fiber formation. Without airflow assistance, fibers tend to accumulate at the edge of the hollow electrode. With the introduction of annular airflow, fibers overcome local electrostatic attraction, pass smoothly through the electrode center, and are uniformly collected via a guiding device, achieving continuous and stable fiber bundling. Systematic experiments revealed that increasing the nozzle–electrode distance led to larger fiber diameters, while higher voltages enhanced electrostatic stretching, refining fibers, although this effect became saturated at high voltages. Enlarging the hollow electrode aperture reduced fiber uniformity. Electric field simulations indicated that solid electrodes provide a uniform and stable field conducive to jet stretching, whereas hollow electrodes induce edge effects, leading to local field concentration and non-uniform field distribution. The introduction of annular airflow effectively mitigates these non-uniformities, significantly improving spinning stability and fiber bundling uniformity. This study clarifies the fiber formation mechanism under the synergistic effects of airflow and electric field and provides a novel strategy for high-quality, continuous melt electrospinning of PP.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"27 5","pages":"2485 - 2496"},"PeriodicalIF":2.3,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733233","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}
