In this study, an attempt was made to explore the dyeing and functional finishing of mulberry silk using extracts from teak (<i>Tectona grandis</i>) leaves utilizing metal mordants. This method enhances the fastness properties, color strength, antibacterial activity, and UV protection ability of the silk fabric. Based on total polyphenols, flavonoids, and antioxidant activity, methanol/water/HCl was considered as the optimized solvent system for functional component extraction from teak leaves. The highest color yield was found to be in the methanol/water solvent system using HCl at pH 2.5 (<i>K/S</i> = 48.338) and temperature at 80 °C (<i>K/S</i> = 28.009) for a dyeing time of 45 min. The dyed silk with alum mordant exhibited good fastness properties (rating 4–5) and the UPF values were highest with silk dyed using a methanol/water/HCl solvent system (UPF = 56.10). The silk fabric showed good antimicrobial activity against <i>Staphylococcus epidermis</i> MTCC435 dyed with methanol/water and methanol/water/HCl solvent extracts using alum mordant. The bonding interactions were demonstrated by X-ray photoelectron spectroscopy (XPS).

In that concern, new stearyl alcohol/polyethylene glycol (SA/PEG) hybrids were synthesized, characterized, and applied as textile finishes to impart cotton/polyester fabric with water repellency. Such hybrids were synthesized by reaction of SA with PEG of molecular weight 1000 or 4000 Da in the presence of ammonium persulfate (APS) as initiator. The optimum conditions of the synthesis reaction are: APS/PEG, 20%; PEG/SA, 15%; reaction temperature, 80 °C and reaction time, 45 min. The synthesized hybrids are self-water dispersible that form oil-in-water stable emulsions. The results indicated that treating cotton/polyester fabric with easy-care finishing formulation containing 60 g/L of dimethyloldihydroxyethylene urea as a cross-linker, and 60 g/L of any of such hybrids emulsions imparts the treated fabric with water repellency, softness, and stiffness properties. Moreover, increasing the PEG molecular weight from 1000 to 4000 Da leads to a reduction in extents of softness and contact angle along with an enhancement in stiffness of treated fabric. Furthermore, the prepared hybrids emulsions-treated fabric samples are durable up to five washing cycles. The FTIR analysis confirmed the chemical structure of the synthesized SA/PEG1000 hybrid. The transmission electron microscope (TEM) revealed that the particles size of SA/PEG4000 hybrid emulsion is in the range of 34–70 nm and reaches to 185 nm in case of the SA/PEG4000 hybrid emulsion.

The present research fabricated sandwich composites using C-glass weft-knitted spacer fabrics and epoxy resin. Three different architectures, i.e., 1 × 1-Rib gaiting, 3 × 3-Rib gaiting, and 5 × 5-Rib, were used to achieve different orientations of Z-fibers. Low-velocity impact test was carried out on the prepared samples. Also, the impact behavior of the sandwich composite was simulated using ABAQUS standard/explicit. The experimental and numerical results show that Z-fibers affect the low-velocity impact behavior of sandwich composites. Based on experiments, the lower maximum reduced acceleration of the impactor and higher contact duration in 3 × 3 Rib-gating means that this specimen has more impact resistance. The indentation percentages of 1 × 1-Rib gaiting, 3 × 3-Rib gaiting, and 5 × 5-Rib gaiting samples were 37%, 34%, and 91%, respectively. In addition, considering the thickness of composites, the experimental indentation of 3 × 3 Rib-gating is lower than other samples which is confirmed by the numerical displacement of the impactor. Numerical analysis showed that the elastic modulus of Z-fibers, its position, and boundary conditions affected stress distribution. The discontinuity among Z-fibers prevents the transfer of stress from the impact area to the outside of this area. Generally, composites reinforced with 3 × 3-Rib gaiting structures show the highest resistance to impact stiffness.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 12","pages":"4807 - 4822"},"PeriodicalIF":2.2,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778091","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}
