Responses of fabric from lyocell/natural bamboo yarn to loading

Abstract

With the growing demand for more comfortable, healthier and environmentally friendly products, research and development has been increasingly focusing on new environmentally friendly materials and products. One of the environmentally friendly materials is the bamboo fibre with its numerous favourable performing properties. The use of bamboo fibres increases every year, which was the main reason for choosing yarn from the mixture of lyocell fibres and natural bamboo fibres with the ratio 80/20 for the research. With the research, the tensile behaviour of woven fabrics with cotton yarn in warp and lyocell/natural bamboo yarn in the weft direction in comparison with cotton woven fabrics was studied. Twelve fabrics which differed in their construction properties were designed and produced. Two different weaves were chosen, i.e. plain and twill weave, and three different densities in weft. The results of the research show that the presence of lyocell/natural bamboo yarn in the weft direction improves the mechanical properties such as breaking stress, stress in the yield point, elasticity modulus in the weft direction of analysed fabrics, while in the warp direction, the weave type and weave density express a greater influence on the mechanical properties of analysed fabrics.
