“…Currently, a considerable amount of lotus stems are left in the pond to be wasted after the blossom season or the harvest of lotus roots. These residues consist of abundant natural cellulose resources which can be used in the textile, paper, medical and construction industries [13]. Extracting fibres from the lotus stems have been in practice since 1910.…”

“…The lotus stems were then washed in deionized water to neutral pH. After that, the fibreswere separated from the lotus stems and named as raw lotus fibres.Preparing fibres with hydrogen peroxide under microwave irradiation has become more and more popular because it is an environment-friendly and efficient method for obtaining cellulose resources [13].…”

Presently, sustainability became a key mantra in all the industries across the world, especially the textile sector as it is one of the largest industries in the world. In textile science, natural fibres have a big role in a sustainable environment-friendly future and became a significant topic to exploit a new natural resource which is green and environment-friendly. Considering this, fibres from various sources were explored by many researchers for its potentialities in improving the quality of life around the world. Aloe vera, banana, sisal, hemp, jute, bamboo, milk fibre, corn, soya, groundnut shell, arecanut, coffee bean waste, lyocell and eucalyptus were few among them. Each year, more synthetic fibres and high energy-consuming products are being replaced by natural-fiber-based products. Additionally, natural fibres have been used not only for clothing but also for technical applications such as composite materials, building materials, filtration and insulation materials. The reason for this trend is not only due to increase environmental awareness but also because of its excellent properties, such as lightweight, strength, low costs and simple sourcing. Meanwhile,waste utilization became one of the important and challengeable jobs around the world. The Textile industry has obtained many fibres from bioresource waste as an important step toward sustainable development. As for example, Pinafibre is a minor fibre obtained from waste pineapple leaves. The study attempted to review some of the selected new sustainable fibres from waste materials and their application in textiles.

“…This treatment attacks the middle lamella holding the fibres together. According to Nair et al [16] or Cheng et al [17], microwaves degrades the polar molecules created in the material during the soaking of the samples mentioned above. Pectin being a more polar molecule than cellulose, it is primarily degraded by the degumming treatment with microwave energy.…”

Fibres from hemp stems can be extracted through different mechanical processes following dew or water retting etc. Extraction processes generally have a significant impact on mechanical and morphological properties of the fibres. In this study, hemp fibres are extracted following three different ways. In the first route hemp fibres are extracted from FUTURA 75 variety stems by performing scutching, hackling and microwave degumming. A second batch of fibres of the same variety was extracted by scutching and hackling after an initial microwave degumming treatment. In the third route, the same variety of hemp fibres are extracted from dew retted stems grown at Piacenza (Italy). Finally, the mechanical properties of single fibres as well as the fineness of technical fibres of all types of extracted fibres are evaluated and compared and the interest of the microwave degumming for hemp stem is evaluated.

“…These residues could be utilized to extract natural fibers which can be then converted to luxury textile products. [6,8] The extraction of lotus fibers from stem residue is the century-old process, which has been in practice since 1910. The conventional methods involve a manual extraction procedure for production of fibers which subsequently handwoven on looms into a luxurious fabric with a silky and smooth feel, which also the most ecofriendly fabric in the world.…”
