A cooking device has been designed and fabricated, by which tasar cocoons can be softened as per standard procedure using solar power plant generated electricity. Cooking efficiency of tasar cocoons remains at par with existing processand no difference of single cocoon reeling parameters and reeling performance softened by newly developed cooking device is observed. Due to difference of solar radiation in different seasons, the cost of cooking/softening varies between Rs. 50/- and Rs. 58/-, while using this device. Although, there is no difference in cooking cost as compared to normal/grid electricity consumption, but 17-30% expenditure can be reduced as compared to existing firewood usage. Utilization of preheated water from solar geyser enhances saving of energy by 12-55% vis-à-vis normal supply of water. In addition to cost effectiveness, this device also reduces the environmental pollution as compared to softening of cocoons using firewood.

Effect of different types of chemical treatments, viz. alkali (NaOH) treatment, trimethoxymethylsilane(Silane) treatment,and combination of both alkali and silane treatment on structural and thermal properties of flax fibres has been investigated bymeans of scanning electron microscopy (SEM), X-Ray diffraction and thermogravimetric (TGA) analysis. Besides, flax fibrereinforced epoxy composites (FFRECs) comprising 45wt.% of fibre reinforcement have been subjected to multi-pass drysliding wear test and experimental runs are conducted as per Taguchi design of experiment technique. Crystallinity index (CI)value of 54.85 is found for alkali-cum-silane (AST) treated fibre, which is 39.23 % and 29.79 % higher than that of untreated(UT) fibre and silane treated (ST) fibre respectively. However, a very mere difference in CI values is observed between alkalitreated (AT) and AST fibres. TGA study shows that UT fibre is thermally stable up to 240°C and this stability is enhanced to310°C owing to chemical alteration as exhibited by AST fibre. Microhardness test indicates minor improvement in the hardnessproperty of the treated FFRECs over the untreated composites. Wear test results reveal that chemically modified FFRECs offerbetter wear resistance than untreated FFRECs and the mechanisms endured by the composites are exposed by SEM. Amongstthe prepared FFRECs, silane-treated FFREC exhibits better wear resistance property. Furthermore, the findings of analysis ofvariance (ANOVA) show that applied load and sliding distance contribute significantly to wear volume loss of FFRECs.

In this study, cotton and polyester fabrics have been coated with different pumice concentrations (3, 6, 9, 12 and 15%) and their physical properties (UV_ultraviolet protective and flame retardancy) are investigated. In addition, the surface properties of the fabrics are also analyzed by scanning electron microscopy, energy dispersive X-ray spectroscopy and contact angle analysis. The findings show that the ignition and yarn breaking times of the fabrics are delayed. The results of untreated fabric samples are compared with the sample coated with 15% pumice. Cotton fabrics shows 79% increase in flame time and 51% increase in yarn break time, while polyester fabric shows 29% increase in flame time and 62% increase in yarn break time. The ultraviolet protection factor values for 3% and 15% pumice-coated polyester fabrics are 50+ and provide excellent protection. It is concluded that the micronized pumice can be a new additive material in the textile industry, especially for use in protective textiles.

An attempt has been made to develop textiles, which can actively repel the mosquitoes from entering into the rooms byimparting nanoparticles in the form of prints. The active material used in the study is eucalyptus leaf nanoparticles in twoforms, viz pre and post calcinated, each in two concentrations. The samples printed with nanoparticles are compared withthe control sample (printed without nanoparticles) for mosquito repellent efficacy against Anopheles mosquitoes, using themodified WHOPES Excito chamber test method. The developed samples are also tested for durability to laundry until 15wash cycles. The results show that the printed samples using eucalyptus leaf extracts in combination with nanoparticles intwo forms have significantly higher mosquito-repellent efficacy. The study also reveals that 90% efficacy is achieved with10% pre and post calcinated nanoparticles. The finding implies that samples printed with 10% pre and post calcinatenanoparticles have high mosquito-repellent efficacy even after 10 wash cycles and have commercial viability. These fabricscan be used for curtains and screens for doorways to reduce the entry of mosquitoes.

Novel fabric that will absorb CO2 in the environment has been produced by coating TiO2 on the fabric surface of apolyester bedspread. The products are characterized by FTIR, EDX and SEM analyses. The parameters, such as the amountof titanium added to the bath and the temperature, are studied to specify maximum CO2 absorption, which ultimately is setas 6 mL titanium source/L and 130ºC (% 95 ram). At the same time, various tests, such as pilling, abrasion, and durability ofthe fabric, are also performed. The fabric sample, thus produced, is also passed through the irritation tests performed byaccredited laboratories.

Thermal comfort behavior of four different types of polyester yarn single jersey knitted fabric has been studied. Spun,micro denier, continuous filament and hollow polyester yarns of 2 linear densities (106 denier and 177denier) have beenused to prepare single jersey fabrics with three loop lengths (0.26 cm, 0.28 cm and 0.3 cm). The air permeability ofcontinuous filament and micro denier yarn knitted fabrics is found to be higher than that of the spun yarn knitted fabrics. Itis observed that 106 denier (0.3 cm loop length)micro denier fabric has the highest air permeability while 177 denier (0.26cm loop length) spun yarn fabric shows the lowest air permeability, as compared to other fabric samples. Comparatively, thelow air permeability characteristics are shown for coarser spun yarn fabric than the finer microdenier fabric. A significantdifference is observed in water permeability among spun yarn, continuous filament yarn and micro denier yarn knittedfabrics at both linear densities of the yarn. The spun yarn of 177 denier single jersey fabric has higher water vapourpermeability and the continuous filament yarn fabric of 177 denier has lower water vapour permeability. The thermalconductivity value of 106 denier continuous filament polyester fabric is higher while that of microdenier polyester is lower.The statistical analysis shows significant difference between two different yarn linear densities and three different looplengths of polyester yarn fabrics. Besides, different yarn and different count have impact on the comfort properties of singlejersey fabrics.

An attempt has been made to highlight the significance of the carding parameters (feeder speed, cylinder speed anddoffer speed) required for fibre of different deniers for regulating the structure and ultimately the properties of the nonwovenfabric. A three-factor three-level Box-Behnken factorial design has been employed to analyse and optimise the cardingparameters. The work focuses on the comprehensive exploration of the functional properties in the light of nonwoven fabricstructures. Regression models of nonlinear process are developed to establish the relationship between specific properties ofnonwoven fabric and structural indices. The optimised carding parameters specific to fibre denier result in improvedfiltration performance of the nonwoven fabric having lower values of fabric thickness, mean flow pore size and pressuredrop, besides acquiring higher filtration efficiency.

The impact of number and order of layers in various sets of multi-layer fabrics has been investigated. Four groups of polyester fabrics with different thicknesses and thermal resistance have been analysed. Moreover, the thermal resistance of various two-, three- and four-layer combinations are evaluated. Results reveal that by increasing the number of layers in a multi-layer set, besides the effect of each layer’s thermal resistance, the formation of air layers between constituent fabric layers, results in a considerable growth in the thermal resistance. Furthermore, it is demonstrated that the order of layers in a specified combination of fabrics, influences the thermal resistance of the multi-layer samples. Statistical analysis of results confirms the significant influence of the number and order of layers on the thermal resistance characteristic of multi-layer fabrics.
