Optimization of chemical activation of cotton fabrics for activated carbon fabrics production using response surface methodology

Abstract

The preparation of activated carbon fabric (ACF) from cotton fabric treated with phosphoric acid (H₃PO₄) was optimized using the response surface methodology (RSM). Experimental activation variables including; impregnation ratio, heating rate, activation temperature, and activation time were optimized based on the responses evaluated (adsorption capacity, yield of the produced ACF). The operation conditions for obtaining the ACFs with the highest the adsorption capacity and process yield were proposed. Optimized conditions were: impregnation ratio of 2, heating rate of 7.5 °C min^?1, the activation temperature of 500 °C, and the activation time of 30 min. The ACFs produced under optimized conditions were characterized by scanning electron microscopy (SEM), X-ray energy dispersion spectroscopy (EDX). The surface area and pore volume of carbon nanostructures were characterized by nitrogen adsorption isotherm at 77 °K using BET method. The obtained results showed that the produced ACFs have developed porous structure, fabric shape, BET surface area (690 m²/g) and total pore volume (0.3216 cm³/g), and well-preserved fibers integrity.

Optimization and performance evaluation of silk fabrics dried in the domestic dryer

To determine the optimal drying procedure for large load and non-ironing procedure for small load when silk fabrics were drying-cared in daily usage; change in appearance, mechanical properties and microstructure of silk fabrics before and after drying with various drying parameters (heater power, air velocity and drum-rotating speed) were investigated. Results revealed that the performance of silk fabric after drying is more sensitive to air velocity (humidity of drying-air) rather than heater power (temperature). Heater power of 3000W, air velocity of 8.5m/s and drum rotating speed of 45-50rpm (No.2) was proved to be optimal for drying silk fabrics due to its ideal smoothness appearance, dimensional stability and drying efficiency. When consumers dry a small amount of clothes, a drying procedure of heater power of 3000W, air velocity of 8.5m/s and drum-rotating speed of 0rpm (No.6) is more reasonable procedure because it reduces or eliminates ironing. And indicating drying in dryer can be an effective alternative to indoor-drying or sunlight-drying if suitable procedure being set. This finding provided reference for manufacturers to design and improve of dryers, especially for drying procedures optimization of delicate textiles, and consumers a feasible care method without reducing the quality of fabric.     

Electromagnetic shielding effectiveness of carbon/stainless steel/polypropylene hybrid yarn-based knitted fabrics and their composites

In this study, a range of conductive hybrid knitted fabrics and their composites have been investigated for shielding effectiveness in the frequency ranges of 50 MHz to 1.5 GHz (low frequency) and 4 to 8 GHz (C-Band). Carbon and stainless steel (SS) filaments were combined in Dref-3 spinning machine and different hybrid yarns were prepared. The plain- and rib-knitted fabrics were made in V-bed flat knitting machine from the prepared hybrid yarns. The composite laminate was prepared by sandwiching a ply of fabric between the polypropylene films in compression moulding machine at 180 °C for 5 min under a consolidation pressure of 12 bar. All the fabrics and composites were tested for shielding effectiveness (SE) in coaxial transmission line and C-band waveguide with the help of vector network analyser. It was observed that fabric having both conductive loop and inlaid yarns exhibited higher SE of 20.2 dB than other fabrics in low-frequency range. However, in the composite form, carbon composite with SS inlaid yarn showed better SE of 45 dB than other composites. In C-band frequency range, conductive loop fabric structures yielded high shielding effect in course direction compared to wales direction. Compared to fabric form, the composite showed higher SE for all frequency ranges. This study proposes that knitted fabrics and their composites can be utilized as electromagnetic shields in wide frequency ranges.     

Filtration efficiency investigation of mesh fabrics by polytetrafluoroethylene filament with surface static electricity

Particulate matter (PM) pollution has become a severe environmental problem. The application of some static electric materials with high filtration efficiency became more and more popular. However, the escape of surface voltage was unbeneficial to the long-term application of this material. Herein, this research reported novel static electric materials polytetrafluoroethylene (PTFE) and tourmaline. With the application of these two materials, a kind of fabric with high surface electricity, filtration efficiency, long-term stability and low pressure drop was exploited. This fabric was woven by PTFE filaments containing tourmaline particles of four different content and particle size. By means of the surface electricity and filtration efficiency measurement, the fabric containing 7 wt % tourmaline particles possessed the largest surface electricity of 830 V, as well as highest filtration efficiency of 75.6%. In addition, a model of electric field distribution in filament and fabrics were both proposed by the static electricity test to interpret the mechanism of filtration. The successful fabrication of such an intriguing material might provide a new application for the electret materials for PM removing.

Dispenser-printed sound-emitting fabrics for applications in the creative fashion and smart architecture industry

This paper presents a printing technology for the design and manufacture of interactive planar speakers. With this technology, sound emission can be easily integrated into various textiles at the design stage with minimal assembly after printing. This paper reports direct-write dispenser-printed sound-emitting smart fabrics, aimed at creative fashion and smart architecture applications opening up new opportunities in product design. Planar spiral speakers generate a membrane vibration and so emit sound when driven from an a.c. audio source if a magnet is in close proximity to the spiral. These speakers can be integrated on fabrics to form the basis of clothing in fashion applications. The speaker designs were printed on woven polyester fabric and produced a measured peak sound output level of 85 dB with a wide frequency response from 20 Hz to 20 kHz. This research demonstrates a straightforward fabrication method, based on dispenser printing, to achieve sound emission from a fabric. The fabrication process requires a processing temperature of 130 °C for 10 min which is compatible with the majority of fabrics which are used in fashion and architecture industries. This paper reports on the theory and the manufacturing technology to achieve direct-write dispenser-printed planar spiral speakers on fabrics.

Development of composite materials reinforced with flat-knitted spacer fabrics

Flat-knitting technology has recently known spectacular developments with the advent of 3D spacer fabrics used as reinforcements of sandwich composites thanks to their improved mechanical properties. At present, studies dealing with the development and the characterization of these composites are quite rare .This work deals with the development of 3D-knitted composite using cotton yarn and unsaturated polyester resin. The aim of this work is to evaluate the utility of a natural reinforcement material in a technical use and assess the impact of fabric cross-link shape on composite mechanical performances. U- and V-shaped 3D spacer fabrics were produced and used to develop composite structures. These structures were characterized by flexion and flat compression tests. Results showed that composites reinforced with U spacer fabric have the best compression resistance whereas the best flexural properties were obtained with V-shaped fabric connection. The developed structures present competitive solution for light weight composites such as solar panels, blades of wind turbines, and sound absorbers.
