Flavonoids-metal salts combination: A facile and efficient route for enhancing the flame retardancy of silk

Mordant Free Dyeing and Functionalization of Wool Fabrics with Biocolorants Derived from Apocynum venetum L. Bast

“…However, no inhibition effect was observed for the dyed fabric when treated with 3 g/L of NaOH dose. This is most likely due to the low quantity of free hydroxyl groups in the corresponding derivatives fixed to the fiber . In addition, S.…”

“…With ever-increasing concerns on ecosafety and human health issues, the utilization of renewable and sustainable biomass resources has become a universal research theme. , Natural dyes, obtained from plants, have been extensively used for the coloration of textiles with fascinating properties such as being biodegradable, ecological, renewable, nontoxic, and nonallergic. − Since flavonoids are naturally occurring pigments, which are highly diversified and are ubiquitous to vascular plants, as well as easily separable with traditional separation methods, researchers have long used these compounds as dyes for dyeing processes. , However, some inherent disadvantages like poor color depth and low colorfastness of the dyed textiles limit their use in modern-day applications. , To overcome these problems, metallic mordants are usually employed by meta-, pre-, and postmordanting procedures . The most commonly used mordants include potassium dichromate, aluminum potassium sulfate, ferrous sulfate, stannous chloride, and copper sulfate .…”

Research on the Development Dilemma and Solution Ideas of China’s Medicine Logistics Under the Development Trend of Contemporary Logistics

“…This is the reason for the establishment of traditional Chinese medicine departments in hospitals and the growth in consumption of traditional Chinese medicine. Through the upgrading of production processes, herbal preparations have evolved step by step from traditional dosage forms such as tonics, poultices, elixirs, pills, dispersants and liquors to new dosage forms such as tablets, capsules, aerosols and injections, which contain multiple active ingredients that show better efficacy than single active compounds and in some cases can exhibit therapeutic effects that are not possible with single compounds and have milder and longer lasting effects with lower toxicity [1].…”

Ultrasonic-Aided Co-Precipitation of Tannins and Chitosan Ammonium Salt on Cotton Fabric for Antimicrobial and Ultraviolet-Shielding Properties: An Efficient, Colourless, and Eco-Finishing Strategy

“…It is more difficult for bio-based extracts to be directly applied to the natural fibres of cotton than to silk or wool, due to the lack of positive sites on cotton for anchoring bio-based extracts. At present, mordanting with metal ions, and cross-linking with additional reactive chemicals, are two common ways to address this issue [11][12][13][14][15]; however, these methods result in annoying colour changes and decreasing functionalities [11,16,17]. Although cotton fibres are often cationised using synthetic quaternary ammonium salts [18], the drawbacks-such as thermal instability, unpleasant odour, and potential health and environmental hazards-greatly hinder their application [18].…”
