  • Development of aerogel-embedded nonwoven fabrics from recycled fibers for thermal insulation applications
    Viju Subramoniapillai, Harish Karthik Deivasigamani
    Research Journal of Textile and Apparel, 2026
    Purpose This research aims to focus on the development of thermal insulation materials through the incorporation of aerogels from sugarcane bagasse into nonwoven fabrics prepared from recycled fibrous waste, such as recycled wool, denim shoddy and recycled cotton. Design/methodology/approach Sugarcane bagasse aerogels were synthesized using polyvinyl alcohol as a binder and freeze-dried to form the final structure. The characterization of the aerogels was then performed. Nonwoven materials made of recycled wool, denim shoddy and cotton were prepared using the carding and needle-punching techniques. These nonwoven composite materials have aerogels embedded using latex adhesives in them. Thermal conductivity testing was used to compare with other available insulation materials. Findings The thermal conductivity of the aerogel-embedded nonwoven fabrics ranged from 33.4 to 41.3 W/m K × 10−3, which is comparable to traditional insulation materials. Practical implications Aerogel-embedded nonwoven fabrics offer effective thermal insulation while efficiently utilizing waste resources. Originality/value This paper is novel for incorporating sugarcane bagasse aerogels combined with recycled textile fibers that gave a novel, thermal insulation material from natural resources in relation to conventional materials in comparison.
  • Oil sorption performance of needle-punched nonwovens made from recycled wool, post-consumer silk waste, and human hair
    Hamsa K. Singh, Thilagavathi Govindarajan, Viju Subramoniapillai
    Journal of the Textile Institute, 2026
    Recycling waste fibers is a valuable strategy to reduce the environmental effects of fiber manufacturing and textile waste. This study used human hair to develop nonwoven fabrics and combined them with other recycled fibers, such as wool and silk, to address the structural challenges of producing 100% nonwoven fabrics using human hair. In this study, six nonwoven fabric structures were fabricated. The fabrics included three single-layer fabrics: 100% Recycled Wool Fiber (100% RWF), 100% Post-consumer Silk Fiber (100% PSF), and a blend of 60% human hair and 40% recycled wool fiber (60% HH/40% RWF), as well as three multi-layered fabrics: Recycled Wool Fiber-Human Hair-Recycled Wool Fiber (RWF + HH + RWF), Post-consumer Silk Fiber-Human Hair-Post-consumer silk fiber (PSF + HH + PSF), and Recycled Wool Fiber-Human Hair-Post-Consumer Silk Fiber (RWF + HH + PSF). The oil sorption capacities of the nonwoven fabrics were evaluated for their application in oil spill cleaning. The findings showed that multilayered nonwoven fabrics absorbed oil more effectively than single-layered fabrics. Notably, the RWF + HH + RWF structure exhibited the highest oil absorption, with values of 42.3 g/g for engine oil and 38.5 g/g for diesel oil. This fabric maintained its oil absorption capacity after five cycles because of the reinforcement of human hair fibers in the middle layer of the fabric. Compared to synthetic materials such as polypropylene, recycled fiber-based sorbents demonstrated superior oil sorption performance, suggesting that multi-layered nonwoven fabrics, particularly RWF + HH + RWF, offer promising and sustainable solutions for oil-spill remediation.

  • Sewing defect detection using YOLOv8: a deep learning approach
    Karthika Latha, Suriya Sundaramoorthy, Viju Subramoniapillai
    Research Journal of Textile and Apparel, 2025
    Purpose The primary objective of this study was to evaluate the performance of the YOLOv8 ((You Only Look Once, version 8)) model in detecting several classes of sewing defects, such as skipped stitches, overlapped stitches, stains and damage and bobbin thread pull-up. The purpose of this study was to develop an effective and accurate method for detecting sewing defects. Design/methodology/approach Initially, data pre-processing and image annotation were performed on the sewing defects, after which YOLOv8 was trained on the annotated data set. The performance was measured using parameters such as precision, recall, mean Average Precision (mAP) and inference time. Findings The YOLOv8 model performed well with a high detection accuracy of 90.5% mAP@0.5 and an average inference time of 24 ms. Practical implications The results indicate that YOLOv8 is efficient in detecting sewing defects in garments, where minor defects can considerably affect garment quality. Originality/value Although prior research has investigated YOLO-based approaches, a notable gap persists in their application to the detection of multi-class sewing defects. To address this, we employ the YOLOv8 model to classify various types of sewing defects.
  • Recycling cigarette butt wastes into nonwoven sorbent for oil spill cleanups
    S. Viju, G. Thilagavathi, U. Priyadharshini, D. Ezhil Adidya
    Journal of the Textile Institute, 2025
    Cigarette butts are currently one of the most littered items in the world. They are non-biodegradable wastes everywhere in the surrounding environment, and preventing them from polluting the environment is challenging. By recycling cigarette butt wastes into new materials and applications, problems associated with cigarette butt waste can be reduced. This work has attempted to produce cellulose acetate-based needle-punched nonwoven fabrics from cigarette butt wastes for the oil spill cleanup process. First, cigarette butt wastes were collected and cleaned, and then cellulose acetate fibres were extracted. In the next step, cellulose acetate fibres were opened by carding, and needle-punched nonwoven fabrics were developed. An experimental design utilizing the Box-Behnken method was used to optimize needle penetration depth, punching density, and fabric weight to maximize oil absorption. The developed sorbent showed a higher oil sorption capacity of 35.6 g/g than polypropylene nonwoven sorbents. As sorbents for oil spill cleanup, nonwovens developed in this study could reduce the environmental hazards associated with cigarette butt wastes and effectively treat pollution caused by oil spills.

  • Development and characterization of DTMS treated nettle fiber nonwovens for oil spill removal applications
    S. Viju, R. Brindha, G. Thilagavathi
    Journal of the Textile Institute, 2023
    In this work, nonwoven oil sorbent from nettle fiber was developed by changing the hydrophilic surface of nettle fiber to a hydrophobic surface by dodecycltrimethoxysialne (DTMS) treatment. Change in the surface structure of the fiber due to DTMS treatment was confirmed by SEM analysis. Fourier transform infrared analyses showed clear evidence of successful incorporation of DTMS on nettle fiber. The oil sorption capacities of diesel oil and crude oil were 31.39 and 41.89 g/g, respectively, which were found to be considerably higher than commercial oil sorbents. The pseudo first order and pseudo second order kinetic equations were employed to obtain the sorption rate constants and equilibrium sorption capacity. The results showed that the process fits the pseudo second-order kinetic model better for oil sorption than the pseudo first-order kinetic model. Also, the sorption capacities of the unmodified and modified samples were estimated by analyzing the isotherm data using Langmuir and Freundlich adsorption isotherm models. The results show that fitting via the Langmuir isotherm model produced a higher correlation coefficient than fitting via the Freundlich isotherm model. DTMS treated nettle nonwoven fabrics also showed good buoyancy characteristics under both static and dynamic conditions. Due to high oil sorption ability, reusability, and environmental responsiveness, the developed nonwoven oil sorbent can be considered as a potential substitute for organic synthetic fiber for oil spill removal applications.
  • Oil spill cleanup by natural fibers: a review
    Viju Subramoniapillai, Govindharajan Thilagavathi
    Research Journal of Textile and Apparel, 2022
    Purpose In recent years, oil spill pollution has become one of the main problems of environmental pollution. Recovering oil by means of sorbent materials is a very promising approach and has acquired more attention due to its high cleanup efficiency. Compared to synthetic fibrous sorbents, the use of natural fibers in oil spill cleanups offers several advantages including environmental friendliness, degradable features and cost-effectiveness. Therefore, studies on developing sorbents using natural fibers for oil spill cleanup applications have become a research hotspot. Design/methodology/approach This paper reviews the work conducted by several researchers in developing oil sorbents from fibers such as cattail, nettle, cotton, milkweed, kapok, populous seed fiber and Metaplexis japonica fiber. Some featured critical parameters influencing the oil sorption capacity of fibrous substrates are discussed. Oil sorption capacity and reusability performance of various fibers are also discussed. Recent developments in oil spill cleanups and test methods for oil sorbents are briefly covered. Findings The main parameters influencing the oil sorption capacity of sorbents are fiber morphological structure, fiber density (g/cc), wax (%), hollowness (%) and water contact angle. An extensive literature review showed that oil sorption capacity is highest for Metaplexis japonica fiber followed by populous seed fiber, kapok, milkweed, cotton, nettle and cattail fiber. After use, the sorbents can be buried under soil or they can also be burned so that they can be vanished from the surface without causing environmental-related issues. Originality/value This review paper aims to summarize research studies conducted related to various natural fibers for oil spill cleanups, fiber structural characteristics influencing oil sorption and recent developments in oil spill cleanups. This work will inspire future researchers with various knowledge backgrounds, particularly, from a sustainability perspective.
