Customized decorticator machine for improved Azorean PALF extraction

This work features for the first time the optimization of Azorean PALF (pineapple leaf fiber) extraction using an innovative adjustable decorticator machine. Additionally, it presents a comparative study on the quality of the extracted fibers compared to those obtained using the conventional hand-scraping method. The main parameters of the customized extraction machine—rotor speed, the horizontal and vertical p...

Selective elastane removal using DMSO–DBN under moderate temperatures: from pur...

Selective removal of elastane from textile blends is a critical factor for fibre-to-fibre recycling, since even low elastane content compromises the mechanical shredding efficiency, contaminates recycled streams, and limits the spinnability of recovered fibres. In this work, we investigate dimethyl sulfoxide (DMSO) as a solvent system for elastane degradation under moderate temperatures, both in the absence and...

Reinforcing cotton recycled fibers for the production of high-quality textile s...

The textile industry is under increasing pressure to adopt sustainable practices due to the significant environmental impacts associated with fiber production, including high energy consumption, water usage, and substantial greenhouse gas emissions. The recycling of textile waste, particularly cotton, is a promising solution that has the potential to reduce landfill waste and decrease the demand for virgin fibe...

Production of nonwoven structures from novel natural fibers: innovation and sus...

Innovative natural fibers from leaves and stems: Explorinf cordyline australis,...

Alternative organic solvents for elastane removal from textile waste: a case st...

The increasing demand for sustainable textile recycling has driven the search for effective methods to separate and recover valuable materials from fabric waste. Elastane, a widely applied synthetic polymer in the textile industry due to its flexibility and durability, presents considerable environmental challenges after the material life cycle. Thus, the development of effective methods for elastane degradatio...

Extraction, characterization and properties evaluation of pineapple leaf fibers...

Pineapple leaves can provide competitive and high-quality fibers for textile purposes. Despite pineapple being cultivated in the Portugues islands there is still a technology gap for the extraction and treatment of Pineapple Leaf Fibers (PALF) in Europe. Since Azorean Pineapple differs significantly from other plants in the bromeliad family, the properties and characterization of its leaf fibers were explored f...

Improving textile circular economy through banana fibers from the leaves centra...

In the last decades, the use of agricultural wastes as a source of natural cellulosic fibers has become urgent, given the growing demand for natural and synthetic fiberss. Cellulose is a renewable natural resource and the most abundant in nature, being obtained from biomass such as wood, cotton and vegetables. Banana fiber is of great interest as bananas are one of the most consumed fruits in the world. Banana ...

Planting sustainability: A comprehensive review of plant fibres in needle-punch...

Natural fibres have garnered substantial attention because of their eco-friendly attributes and versatility, offering a sustainable alternative to synthetic ones. This review surveys plant fibres, including flax, hemp, jute, banana, and pineapple, emphasizing their diverse properties and applications in nonwoven materials. This research also examines the use of synthetic polymer composites blended with natural ...
