The effects of hybridization on compressive instability failure are analysed by varying the glass fiber volume percentage in a composite. The study examines the compressive instability failure of the composite, considering the non-linear constitutive behaviour of the polymer matrix and initial morphological defects. Each glass and carbon fiber is modelled using 3D finite element micromechanical models. Linear buckling analysis is conducted with appropriately scaled faults. The Thermal analysis to determine heat distribution over the tray, carried out using COMSOL Multiphysics tool, solar greenhouse dryers are used to dehydrate agricultural products, preserving them for longer periods and improving their market value. The materials used in these dryer trays must meet specific performance criteria to ensure optimal drying conditions. In Greenhouse solar dryers, two commonly used tray configurations such as Stable Tray-Assisted Dryer (STAD) and Rotatable Tray-Assisted Dryer (RTAD) are considered in this study and the glass-carbon hybrid composite used in solar greenhouse dryer trays Introduced as Hybrid composite Rotatable Tray-Assisted Dryer (HRTAD), offers significant contributions by ensuring uniform and effective moisture removal and their excellent strength-to-weight ratio, corrosion resistance, heat resistance, sustainability, and long life. These properties make them a dependable and effective solution for building solar dryer components, assuring optimal performance and contributing to the overall success of solar greenhouse systems. Hybrid glass fiber composites offer several advantages that make them particularly suitable for this application.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 10","pages":"3995 - 4006"},"PeriodicalIF":2.2,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142412604","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}

Although the effective thermal conductivity of a porous medium is a combination of both diffuse and radiative thermal conductivity, using an alternate approach, the present work attempted to quantify the influence of structural parameters on radiative transmittance, which is directly related to radiative conductivity that affect the overall effective thermal conductivity. A Box–Behnken design was used to study the effect of areal density, thickness of nonwovens, and blend proportion of the goose down fibres in non-wovens on the radiative transmittance. It was found that radiative transmittance does not decrease linearly with an increase in areal density. Also, the model predicted an interaction factor among the thickness of the nonwoven and the blend proportion of the goose down fibers; with an increase in thickness, radiative transmittance showed a decreasing trend; with an increase in goose down blend proportion, radiative transmittance decreased, but the extent of reduction was different for different levels of thickness. So, it was found that the multidirectional orientation of goose down fibres along with their fine barbules are the major factors that contributed to their lower radiative transmittance properties.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 10","pages":"4033 - 4044"},"PeriodicalIF":2.2,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250632","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}

For viscose fabric, several dyeing processes were performed utilizing natural mordants, such as orange peel and lemon peel, as well as commonly used tannic acid, copper sulfate, and ferrous sulfate with various mordanting ratios. In the entire experiment, for the first time, only one type of mordanting procedure (pre-mordanting) was used to determine the optimal outcomes of the mordants and to provide a comparison of their performances. The results revealed that viscose fabric dyeing using a pre-mordanting method with 5% orange peel as a natural mordant exhibited improved performance and higher outcomes than the other mordants. Different measurement techniques were used to determine the CIELab outputs, and a color strength (<i>K</i>/<i>S</i>) attribute experiment was used to determine the optimal value. The results from the FTIR study verified that the colored particles interacted with the viscose fabric. In addition, the results from the SEM analysis confirmed the ability of the dye to absorb into the viscose fabric surface.

PVDF stands out as the material of choice in piezoelectric generator technology owing to its remarkable flexibility, superior processability, long-term stability, and biocompatibility. Nevertheless, PVDF-based generators exhibit inferior piezoelectric responses compared to traditional piezoelectric ceramic materials, thereby constraining their performance in large-scale deployments. To address this limitation, researchers have been exploring innovative strategies to enhance the piezoelectric properties of PVDF. Among these, electrospinning technology emerges as a pivotal approach due to its ability to impart mechanical stretching and in situ polarization to the polymer during fabrication. This paper comprehensively reviews recent advancements in optimizing the output performance of PVDF-based piezoelectric nanofiber membranes through the integration of filler doping technology with electrospinning. We delve into the effects of various filler types on the properties of electrospun PVDF-based piezoelectric nanofiber membranes and explore their underlying mechanisms. These fillers significantly bolster the output performance of PVDF-based piezoelectric devices by augmenting PVDF's piezoelectric activity, fostering dipole orientation, and elevating the dielectric constant. Notably, the incorporation of fillers not only elevates the piezoelectric coefficient but also optimizes the microstructure, facilitating an efficient conversion between mechanical and electrical energy. Furthermore, we envision the promising application prospects of PVDF piezoelectric nanofibers in cutting-edge fields, such as health monitoring, environmental monitoring, and energy-harvesting systems. These domains urgently require piezoelectric materials that combine high sensitivity, stability, and cost-effectiveness, where PVDF-based piezoelectric nanofibers, with their distinctive advantages, are poised to demonstrate significant application potential and societal value.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 11","pages":"4075 - 4098"},"PeriodicalIF":2.2,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268586","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 paper presents an approach to develop a PCM-loaded composite yarn for potential use in medical textiles. Paraffin wax-based PCM nanocapsules were synthesized and integrated into cotton fibers during the ring spinning process. Subsequently, a composite core–shell-structured yarn was fabricated using electrospinning, comprising a cotton/PCM core and a poly (<span>l</span>-lactic acid) (PLLA)/PCM nanofibrous shell. Morphological analysis confirmed the successful formation of the core–shell structure and the uniform distribution of PCM nanocapsules within the fibers. The composite yarns exhibited reduced diameters with increasing PCM nanocapsule content. Thermal analysis revealed that the incorporation of PCMs resulted in decreased glass transition and cold crystallization temperatures of the PLLA nanofibers. Additionally, the presence of PCMs increased the crystallinity of PLLA fibers. According to the thermoregulation test results, the presence of PCM in its structure affected the heating and cooling behavior of the yarns. The composite yarns were further functionalized by incorporating Vancomycin as an antibiotic agent for medical dressing applications.
