“…It is clear that where the composite density increased, the airflow resistance decreased due to increased resistance to airflow caused by the consolidation of the bonding materials, but also increased the short fiber content which will occupy the air voids. The above said results are in line with the findings of Sakthivel et al 20,21 Influence of specific porosity Ramlee et al 18 stated that, in designing a coir/jute fiber, composites have a high thermal insulation value, and porosity should increase along the propagation of the temperature. Thus, from Figure 3 the sample of (S4C/J) has specific porosity of 1.93% and a thermal insulation value of 0.07056%.…”

Thermal comfort property is closely related to the concept of thermal insulation and includes protection against heat. This research paper presents an experimental study on thermal insulation properties, for natural fiber composite materials: a natural fiber (Coir/Jute) with different blend proportions of raw materials mixed with rigid polyurethane foam as a binder. The natural fiber composite materials were characterized by both thermal resistance (Thermal Insulation Value TIV) and also in terms of heat transfer (thermal conductivity). Thermal insulation values were measured according to Lee’s disk method (ASTM C177). The influence of the structure of these materials on the thermal insulating properties was analyzed. The experimental results show the thermal resistance performances of natural fiber composites based on coir/jute fiber materials, thus promoting environmentally friendly solutions.

“…Most probable reason for this situation might be the decreasing contact area between abrader and the fibers that cause damage in yarn structure easily after the abrasive movements. e same results were obtained by Melese et al and Rosace and Massafra [21,22].…”

The uses of recycled materials have gained massive importance in the textile sector and other application areas as the effects of reducing natural resources are felt worldwide. This study aimed to analyze the effects of recycled fiber usage on the properties of OE-rotor spun yarns and hand-woven fabrics produced from these yarns. For this purpose, OE-rotor yarns are produced at different proportion levels from virgin cotton and recycled fibers derived from knitted garment wastes at 25%, 50%, and 75%, respectively. For a better assessment, properties of OE-rotor yarns that contain recycled fibers and 100% virgin cotton OE-rotor yarns are compared. Physical, structural, and mechanical properties such as unevenness, imperfections, hairiness, breaking force, and elongation are analyzed by Uster Tester 5 SX, Uster Zweigle Hairiness Tester 5, and Uster Tensorapid 3. Plain and twill hand-woven fabrics are produced from OE-rotor spun yarns. Effects of recycled fiber proportion on hand-woven fabric properties such as pilling, abrasion resistance, and air permeability were also evaluated. Results showed that the use of up to 75% of recycled fiber cotton blended yarns shows no statistically significant differences in yarn and fabric properties.

“…Another factor was the tortuosity component. 12 The natural fiber composite samples can be observed that while frequency increases, sound absorption coefficient (SAC) of all samples is BBC-A (0.0230%), BBC-B (0.033%), BBC-C (0.061%), BBC-D (0.065%), and BBC-E (0.113%) also increases. Similarly, while thickness increases the sound-absorbing performance also increases.…”

This research paper reports a study on thermal and sound insulation samples developed from sugarcane bagasse and bamboo charcoal for automotive industry applications. The sugarcane bagasse and bamboo charcoal fiber is a potential source of raw material that can be considered for thermal and sound insulation applications. Natural fibers are commonly used in diverse applications and one of the most important applications is sound absorption. Natural fiber hybrid composite currently is in greater demand in industries because of their advantages such as low cost, biodegradability, acceptable physical properties, and so on. Eco-friendly sound-absorbing composite materials have been developed using bamboo charcoal and sugarcane bagasse fibers. From these fibers five types of natural fiber green composite were developed using the compression bonding technique. The natural composite noise control performance contributes to its wider adoption as sound absorbers. The sound absorption coefficient was measured according to ASTM E 1050 by the Impedance tube method. The physical properties of natural fiber composites such as thickness, density, porosity, air permeability, and thermal conductivity were analyzed for all samples in accordance with ASTM Standard. The result exposed that natural fiber green composite were absorbing the sound resistance of more than 70% and the natural fibers composites provide the best acoustic absorption properties, these composite materials have adequate moisture resistance at high humidity conditions without affecting the insulation and acoustic properties.
