Study of thermal properties of jute and hollow conjugated polyester fibre reinforced non-woven composite

Abstract

Sandwich structure of non-woven composite is produced by using a compressive hot pressing method. It is ranging from 2500 grams per square meter (gsm) to 3500 gsm. Composite sample is designed using Box and Behnken model. Considering 50-70% weight of jute fibre content with 30-50% weight of hollow conjugated polyester fibre, ideal thickness of the composites is maintained in the range from 4 to 5 mm. Thermal properties such as thermal conductivity, thermal resistance, thermal transmittance and thermal diffusivity were evaluated by considering three factors: weight of jute (A), weight of hollow conjugated polyester (B) and thickness of the composite (C). The thermal conductivity of the composite material is determined by heat flow meter method ASTM C518. Experiment result will help to make a suitable standardized panel composite for thermal insulation. It requires 3600 gsm 51/49 parts of contribution of jute/hollow conjugated polyester fibre with 5.0 mm thickness and 3200 gsm 76.5/23.5 parts of contribution of jute/hollow conjugated polyester fibre with 4.5 mm thickness of the composites. The composite weight of 3280 gsm shown optimized thermal responses, it was predicted from response surface method graph. Contribution of jute/hollow conjugated polyester fibre of 54/46 parts with 5.0 mm thickness would be considered to make standardized composite panel. Mostly air conditioning process reduces the energy cost spent for the thermal stability in indoor climate of dwellings.

Fabrication of antistatic fibers with core/sheath and segmented-pie configurations

“…Such composite fibers, e.g. concentric core/sheath (Figure 1(a)), eccentric core/sheath (Figure 1(b)), 50/50 side-by-side (Figure 1(c)), unequal side-by-side, (Figure 1(d)), island-in-the-sea (Figure 1(e)), and segmented-pie fibers (Figure 1(f)), are widely manufactured in the textile industry [9–16]. Zhao and Liu [15] demonstrated that core/sheath fibers could reduce the energy consumption in the following application process, while side-by-side fibers can maintain their three-dimensional heterostructure after hot-stretching processing.…”

Morpho-phenetical study of high yielding tossa jute variety BJRI Tossa Pat 7 (MG-1) for bast fibre yield and qualities

“…Plant population: In farmer's plot, MG-1 gave higher plant population (4.60 L ha À1 ) at Chandina station and the lowest plant population (0.92 L Table 4. Physical properties of jute fiber (IJIRA, 2012; Roy and Lutfar, 2012;Pujari et al, 2014;Zakriya et al, 2015;Banerjee et al, 2015;Shahid et al, 2016;Sathishkumar et al, 2017;Khan et al, 2020) ha À1 ) at Monirampur during 2016-17 (Table 9). In respect of means over year, this genotype showed higher plant population (3.40 L ha À1 ) with the mean of 1.63 L plant ha À1 (Table 9).…”

Jute-reinforced non-woven composites as a thermal insulator and sound absorber – A review

“…57 Juan et al 58 found that jute/polyester resin skins have a thermal conductivity value of 0.092 W/m.K and jute fibre honey comb have a thermal conductivity value of 0.094 W/m.K shown the best performance insulator Value. Zakriya et al 59 in their research work of thermal properties of jute and hollow-conjugated polyester fibre-reinforced nonwoven composite, the thermal conductivity value 0.0193W/m.K is predicted by response surface method graph. 59 A material can be considered as an appropriate thermal insulator if its thermal conductivity is 0.15 W/m.K or less.…”
