“…The first successful reported studies were on the incorporation of dyes in the silkworm diet. ,,− Recently, the incorporation of nanomaterials has gained an enormous interest due to the potential application of the produced SFs in the biomedical and technological fields. Different types of nanomaterials were fed to silkworms.…”

Silk has been used in several biomedical applications, including tissue engineering, drug delivery systems, biomedical implants, and diagnostic medical devices, due to its attractive intrinsic properties such as biocompatibility, controllable biodegradability, and excellent mechanical properties. In recent years, several attempts have been made to produce silk fibers with improved properties and new functionalities by feeding silkworms with modified diets containing nanomaterials. Nanomaterials possess unique physical, chemical, and biological properties and when combined with silk can expand its applicability for biomedical applications. Feeding silkworms with modified diets containing nanomaterials is a greener method of producing functionalized silk fibers when compared to the alternative postfunctionalization methods that include multistep procedures and toxic chemicals. The main advantages of using this greener method are related to the reduced usage of resources such as water, energy, and additional chemicals to spin functional silk fibers, the maintenance of intrinsic silk properties, the stability of the added new functionalities, and the possibility of large-scale production. Feeding silkworms with different nanomaterials such as carbon-based nanomaterials, metal and metal oxide nanoparticles, and quantum dots has led to the production of silk fibers with improved properties (e.g., mechanical and thermal) and/or new functionalities (e.g., magnetical and luminescence). However, nanomaterials concentration, dimensions, and solubility were shown to influence their uptake by silkworms as well as silk fiber properties. Here, we review the literature that focuses on the feeding of silkworms with nanomaterials, highlighting the acquired new functionalities and improved properties of the obtained greener and more sustainable silk fibers.

“…Silk is a natural fiber with a wide market throughout the world. Traditionally, household spinners and weavers produce a variety of beautifully coloured fabrics for both domestic and ceremonial uses by blending different colors (Kanika et al, 2016). China and India are the best silk producing countries.…”

Insects provide a wild variety of uses and benefits ranging from Agriculture to medicine, industries and research. They have been reared for food, feed, silk production and dye making. Recently, a lot attention has been drawn worldwide to the usefulness of insect in the food and feed industry because of their high nutrition contents and environmental sustainability. For these reasons, a lot of insect based entrepreneurs have sprung up in Africa in response to this development, but in Nigeria only few entrepreneurs are interested in engaging in insect farming due to information gap. This research aims to bridge the gap by identifying species of insects that can be farmed, for what purpose they are farmed, potentials embedded in insect product development, and factors affecting edible insect entrepreneurs in Nigeria. Data were sourced by querying many research databases outlets such as science direct, researchgates, google scholar, Ajol and so on. This research identifies palm weevil, crickets, grasshopper and pallid emperor moth as insect that can be farmed with high demand as food in Nigeria. The maggot of housefly and Black soldier fly are recommended for animal feed and silk warm for textile industry. The review recommends that the government should encourage insect entrepreneurs in Nigeria through training and improve extension services.

“…In order to solve the abovementioned problems and wastewater issues, many studies on the self-dyeing method of silkworms by feeding silkworm leaves with dyestuff have been studied, and this method helps to reduce water use by almost 100% compared to the conventional dyeing process (Kang et al, 2011;Tansil et al, 2011;Nisal et al, 2014;Trivedy et al, 2016). In these studies, the uptake of azo dyes (Brilliant yellow, Congo Red, Acid Orange G, Acid Orange II, Mordant Black 17, Direct Acid Fast Red and Sudan III) into silk glands for the production of self-dyed silk and quantification of these dyes in sericin and fibroin were thoroughly discovered and discussed.…”

PurposeThe textile industry has consumed large quantities of water and discharged large volumes of wastewater in the dyeing process. The study aims to characterize self-dyed silk with Rhodamine B (RhB) for fashion applications to reduce textile hazards to the environment and increase the added value of silk.Design/methodology/approachBombyx mori was fed with RhB-colored mulberry leaves (1500 ppm). The effects of self-dyeing were investigated via color strength K/S, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscope, X-ray diffraction, tensile strength, color fastness to washing, rubbing, perspiration and light.FindingsSelf-dyed silk possesses effective coloration and impressive color fastness (4–5/5), higher crystalline index (CrI) (73.26 ± 2.28%), less thermal stability and tenacity, slight change in amino acid composition compared with the pristine and no existence of harmful aromatic azo amines and arylamine salts.Practical implicationsThe application of self-dyed silk with RhB dye has expanded new technology into fashion industry, contributing partly to economic growth and adding value to silk in the global supply chain. Besides, the self-dyeing will yield practical values in the reduction of dyeing discharge in textile industry.Originality/valueSelf-dyed silk was characterized for textile applications in comparison with pristine silk in terms of color strength and fastness as well as determined its polymeric properties relating to crystallinity, morphology, chemical composition, tensile properties and thermal stability which have not been investigated before.
