Insufficient resources of plant fibre for developing bio-based products and processing fibrous plant stalks to high quality and quantity fibres are two challenges of the natural fibre industry. Considering the first challenge, two alternative plant fibres including canola and sweet clover fibres were characterized and compared to hemp and flax fibres which are two traditional fibres. Their characteristics, including microstructural, surface, thermal, and mechanical properties, were measured. Mechanical behaviour of fibres was also simulated using the Discrete Element Method (DEM). Considering the second challenge, fibre extraction experiments were conducted on both traditional and alternative fibrous plants. In the experiments, hemp fibre was mechanically extracted using a decorticator. Mechanical extraction of canola fibres was not successful; therefore, canola fibre was extracted through retting. Results demonstrated that the microstructural, surface, and thermal properties of the alternative fibres (canola and sweet clover) were in the same ranges with the traditional fibres (hemp and flax). However, the alternative fibres had lower Young's modulus, while the traditional fibres had higher stiffness and tensile strength. Simulation results indicated that the DEM model generated comparable results to the tensile test experiments in terms of Young's modulus and tensile strength. For mechanical extraction of hemp fibre using the decorticator, the most effective parameters, in terms of quantity and quality of the fibres, were the retting condition of the feed stalks, the number of pass of stalks through the decorticator rollers, and the feed amount. For retting extraction of canola fibre using chemical solution, when the time, temperature, and NaHCO3 concentration were set to 37.8 h, 57.7 oC, and 5.62%, respectively, the highest quantity and quality canola fibres were achieved. The results from this study have important implications to applications of plant fibres.

This is the last of the Small-scale Textile series and covers the pre-spinning processes which make plant fibres suitable for textile manufacture. The book includes not only familiar plant fibres such as cotton, sisal and jute, but also less well known fibres from plants such as Himalayan nettle, pineapple leaf and kenaf, which are of great value to small communities where they are used for both utilitarian and decorative purposes. As well as extraction and other pre-spinning processes, there is background information on the growing areas, soil and climatic requirements and methods of harvesting, and details of equipment suppliers and sources of further information.

Natural fibers production, processing and export are vital to the economies of many developing countries and the livelihoods of millions of small scale farmers and low wage workers. Almost all natural fibers are produced by agriculture, and the major part is harvested in the developing world. It is convenient to classify natural fiber in two ways; morphologically, according to the part of plant from which they are obtained and practically according to the uses to which they are put, which in turn depend on their properties. From the view point of the uses vegetable fibers may be classified into following groups; textile fibers, cordage fibers, brush and mat fibers, stuffing and upholstery materials, paper making materials etc. Fibers from the view point of the part are classified as hair fibers, leaf fibers, woody fibers, bast fibers, etc. The use of fibers for paper making differs completely from their use in textiles, in that in papermaking it is ultimate fiber cells which are used; thus in papermaking process consists in breaking down the strands of fiber into the ultimate fibers. Jute, the most important textile fiber apart from cotton, is obtained from two species of corchorus(white jute) and C.olitoriusL. (tossa jute). Farmers around the world produce a wide variety of natural fibres, planting crops and rearing animals. Plant fibres may be from the plant fruit (e.g. cotton), stems (e.g. flax and jute) or leaf (e.g.sisal). Natural fibres are generally considered more environment friendly than synthetics in their production and disposal. However, there is great variation depending on the fibre and the growing conditions. Many chemicals are used to contain pests and weeds. Chemicals are also used in the processing and dyeing which can lead to water contamination. Processing of some natural fibers can lead to high levels of water pollutants, but they consist mostly of biodegradable compounds, in contrast to the persistent chemicals, including heavy metals, released in the effluent from synthetic fiber processing. Farming and production of natural fibres also plays a significant role in eradicating poverty as an important source of farming income and contribution to food security in developing countries. Demand for natural fiber composites are largely driven by increasing environmental awareness. Due to low cost, low density, acceptable specific properties, ease of separation, enhanced energy recovery, CO2 neutrality, biodegradability and recyclable properties, natural fiber use in composites is gaining as demand grows for component materials that are durable, reliable, light weight, with mechanical properties better than those of traditional materials. Total global natural fiber composite market expected to grow at 11% CAGR. Some of the fundamentals of the book are the occurrence and nature of vegetable fibres, conditions necessary for growing flax, mulberry family (moraceae), lime family (titliaceae), experiments on mechanized production of jute, mallow family (malvaceae), kenaf production in various other countries, the use of unretted kenaf ribbons for sack manufacture, pea family (leguminosae), sterculia family (sterculiaceae), agave family (agavaceae), structure of the sisal industry, narcissus family (amaryllidaceae), lily family (liliaceae), pineapple family (bromeliaceae), fibres from other species of musa and a related genus, brush making fibres, etc. The book contains process and other parameters for the manufacturing of fibers arrive from natural sources. Due to eco friendly nature there is very good domestic and export potentiality for natural fiber. This is very useful book for new generation entrepreneurs, consultant institutional libraries, and existing units.

Complex raw materials and manufacturing processes mean the textile industry is particularly dependent on good process control to produce high and consistent product quality. Monitoring and controlling process variables during the textile manufacturing process also minimises waste, costs and environmental impact. Process control in textile manufacturing provides an important overview of the fundamentals and applications of process control methods.Part one introduces key issues associated with process control and principles of control systems in textile manufacturing. Testing and statistical quality control are also discussed before part two goes on to consider control in fibre production and yarn manufacture. Chapters review process and quality control in natural and synthetic textile fibre cultivation, blowroom, carding, drawing and combing. Process control in ring and rotor spinning and maintenance of yarn spinning machines are also discussed. Finally part three explores process control in the manufacture of knitted, woven, nonwoven textiles and colouration and finishing, with a final discussion of process control in apparel manufacturing.With its distinguished editors and international team of expert contributors, Process control in textile manufacturing is an essential guide for textile engineers and manufacturers involved in the processing of textiles, as well as academic researchers in this field.
