“…The bamboo is used as weft yarn and the cotton yarn is used as warp yarn for getting high strength fabric. 57 The mechanical properties of cotton and bamboo woven fabric has significant improvement when cotton yarn is used as warp and bamboo yarn used as weft and the maximum tensile strength is achieved by this blended fabric is 579.53 N in the warp way and weft way has tensile strength of 500.07 N as shown in Figure 3. This is due to more interlacement of plain woven fabric and high strength of cotton warp yarn.Figure 3.Analysis of breaking force for simple fabric under both directions.…”
Due to the increasing demand for environmentally safe products, the use of composites manufactured from natural fibres has become one of the most widely researched subjects lately. In this present study, the influence of weave designs on the mechanical characteristics of bio-based cotton, bamboo and cotton/bamboo fabric reinforced textile epoxy composites is presented. The textile composites were prepared by compression moulding process with different fabric weight ratio of 70:30; 65:35; 60:40; 55:45 and 50:50. The composites were tested for interlaminar shear, flexural, compressive, tensile and impact strength as per ASTM standards. Compared to other weave design composite laminates, 45 wt.% loading of cotton and bamboo textile composite achieved the greatest results for all the tests in a simple weave pattern. The scanning electron microscopy results of the fractured samples exhibited superior interfacial bonding between the fabric and matrix, as evidenced by the presence of significantly reduced fibre bend, fibre pullout, tearing and crack. The prepared natural fibre composites (cotton/bamboo) can be used as an eco-friendly alternative to man-made materials that aid in pollution management. They are also less expensive, have higher mechanical characteristics and use less energy in the manufacturing process.

“…The changes observed in fibre morphology by mercerisation [98,99] (including deconvolution, a decrease in the size of the lumen, and a more circular cross section) appeared accordingly. In contrast, sample 10_1 showed a different morphology, which could be attributed to cotton treated with liquid ammonia [100], or to a regenerated fibre such as lyocell [101]. However, cotton treated with liquid ammonia, which turns from cellulose I to III, should only show the peak at 3484 cm −1 [56,100], while the peak at 3439 cm −1 also appeared.…”
Section: Case Study: Traditional Samurai Armoursmentioning
This paper presents the limitations and potential of ATR-FTIR spectroscopy applied to the study of cellulosic textile collections The technique helps to differentiate natural fibres according to the content of lignin, pectin, hemicellulose, and wax, although some problematic issues should be considered. The spectral differences derived from the environmental humidity uptake and the plant composition are reviewed and discussed in the light of new experimental data. Diagnostic bands are proposed that can discriminate between different fibres from different plants. The contribution of ageing is also considered, demonstrating that sometimes aged fibres cannot be reliably recognised. In contrast, the potential of ATR-FTIR spectroscopy to discriminate between natural and modified fibres is discussed and proven. The best results were obtained when microinvasive ATR-FTIR spectroscopy was coupled with SEM observations. The proposed protocol was tested on microsamples of various cellulosic materials from traditional Japanese samurai armours dating from the 16th to the 20th centuries (Morigi Collection, Museo delle Culture, Lugano, Switzerland). The results facilitated a complete characterisation of the materials and demonstrated that the protocol can be used to study a wide variety of cellulosic materials, including both natural and man-modified fibres, and paper.
