Article
Full-text available
Due to the ever-growing demand for bast fibres for technical and garment textiles, complementary sources to textile flax, whose cultivation in western Europe cannot really be extended, need to be proposed. In this study, the interest in harvesting and processing linseed flax straw is studied for geotextile applications. The main critical stages of...
Article
Full-text available
Hemp is a sustainable source of natural fibres that can contribute to meet the increasing demand for technical applications in the textile and the composite sectors. Continuous reinforcements can be produced using the existing flax machinery, initially developed for textile purposes. To achieve competitive and economically viable fibre yields and a...
Article
Linseed flax is an oilseed producing crop but its stems are rich in high potential fibers. However, linseed flax is not highly promoted for fiber application purposes. It is mainly due to the lack of technical knowledge regarding good quality fiber extraction from linseed stems. In this study, a fiber extraction device has been used to extract fibe...

Recycling of thermoplastic composites has drawn a considerable attention in the recent years. However, the main issue with recycled composites is their inferior mechanical properties compared to the virgin ones. In this present study, an alternative route to the traditional mechanical recycling technique of thermoplastic composites has been investi...
Article
Full-text available
Increasing the production of high-performance natural fibres that minimise their impact on the environment is a challenge that flax (Linum usitatissinum L.) cannot address alone. In flax traditional production territories, hemp (Cannabis sativa L.) can be a complementary source of high added value fibres if their yield of long line fibres can be ma...
Article
Following their mechanical extraction, the fibers coming from the banana pseudo-stem are coarse and the inter fiber cohesive substances need to be removed before their transformation into textile yarns/technical textiles. To reach this objective, dry-coarse banana fibers previously extracted using compressive rollers are treated using an oil-water-...

Antiviral textiles are one of the most promising areas of protective textiles. Antiviral textiles are important in the field of health and hygiene. They become an essential part of our daily-life when a pandemic situation arises. The present paper critically analyses and summarizes various researches of the production of antiviral textiles. Differe...
Article
Retting of fibrous plants such as flax is an essential step in the extraction of fibre bundles and their transformation into textiles and reinforcement fabrics for use in garments and composites. Dew-retting is traditionally performed from Northwest France to the Netherlands, as the climate is highly favourable for this process. Hemp is a plant tha...
Article
Resistance to impact thrust is one of the most important requirement along with many others for defining suitable applications of any composite materials. In this present work, the influence of composite architecture and composite interfacial bonding strength on the impact performance of flax reinforced PP composites have been investigated. In this...
Article

Croton bonplandianum (C. bonplandianum) is a monoecious exotic weed belonging to the euphorbiaceae family, is grown unwantedly at a large scale in the cultivation land of eastern India, along with the main crop. In this present work, sap from the C. bonplandianum plant is extracted through aqueous extraction method, which is further applied on cott...
Article
Flax-PP based thermally bonded roving (TBR) has a unique structure where the flax fibres remain twist-free and fully aligned along the roving axis. The present study describes an experimental investigation on the low velocity impact (LVI) behaviour of the TBR based woven fabric composites and compares the same with plain woven glass fabric reinforc...
Article
Full-text available
In the current context of environmental contamination due to disposal of textile-manufacturing waste, substitution of synthetic dyes and chemicals with bio-colour or bio-extract is a big confront. Thus, the need of the hour is to develop green chemicals or dyes for sustainable textile processing with an eco-friendly approach. In light of above, a b...
Article
In the present work, a novel, flax-polypropylene (PP) based twist-less, thermally bonded, flexible roving has been produced in a specially designed machine. Fibres in the roving are highly oriented towards the roving axis and are held together by means of thermoplastic resin. This type of twist-less rovings is expected to provide better strength tr...
Article
Full-text available
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 fr...
Article
The main objective of this work is to study the effect of composite architecture on the mechanical properties of flax reinforced polypropylene (PP) composites. In this context, two different hybrid yarn structures using flax and polypropylene (PP) fibres have been produced; one, through the friction spinning method and the other through thermal bon...
Article
Full-text available
Flax has a short fiber length that makes the control of fiber orientation in the composite structure very difficult, which leads to composites with inferior mechanical properties. In order to overcome this difficulty, thermally bonded roving (TBR) with a novel structure where the flax fibers are in a twistfree state and are highly oriented to the r...

Protective textiles are saving human beings from various adverse environmental conditions like fire, heat, bullets, microorganisms, mosquito bites, etc. In connection with flame-resistant textiles, fish DNA, casein, whey protein, and wastage plantbased bio-macromolecules, such as spinach juice, banana pseudostem sap, coconut shell extract, and so o...
Article
In the present work, the influence of interface and hybrid yarn structure on flax-PP based unidirectional composite properties have been studied thoroughly. Flax-PP based core-sheath structured DREF spun hybrid yarns are manufactured after varying the core yarn twist and sheath percentage at three different levels and using MAgPP treated and untrea...
Article
In the present study, two distinguishable unidirectional composite structures have been produced using compression molding technique. Among these two, one is made through conventional film stacking (FSC) method while the other structure is made after consolidating the DREF spun hybrid yarns (DYC). In both cases, low twisted, MAgPP treated flax yarn...
Chapter
Natural fibre reinforced thermoplastic composite materials are becoming very popular in the material community due to several advantages of natural fibre and thermoplastic polymer. The demand of stronger and better composite than the existing ones is also increasing simultaneously with their growing popularity. However, natural fibre reinforced the...
Article
In this present study, thermally treated flax–polypropylene (PP) based hybrid yarns have been manufactured using DREF-3 spinning method for thermoplastic composite reinforcement. The effect of different process parameters such as core yarn twist level, sheath ratio and thermal treatment temperature on hybrid yarn properties has been studied thoroug...
Article
In the present study, an attempt has been made to convert sericin into film form and further make it insoluble by forming sericin–aluminum metal complex using alum salt, which may lead to some extent of cross-linking. After complex formation sericin becomes insoluble in warm water as well as thermal stability and tensile strength improves significa...

In this review article, different approaches of enhancing flame retardancy of polymeric composite material and their effect on different composite properties are analysed critically. The mechanisms of fire spreading on composite materials are also discussed. Flame retardancy of polymeric composite material can be enhanced either by enhancing the fi...
