Due to its very good mechanical properties at low density, wood is a high potential and sustainable raw material for composite applications. Wood as small particles are commonly processed with polymers to Wood-Polymer-Composites (WPC). Thereby, the inherent strength of the wood is not used to its full potential. In order to transfer the strength properties of solid wood with good shaping properties to composite, wood wool properties were studied. Wood wool is a well-known raw material in the wood-processing industry and is mainly used for packaging, animal bedding and insulation boards [1, 2]. The use of wood wool as a flexible, formable reinforcement for polymer composites is not known so far. Therefore industrial wood wool and developed experimental wood wool are investigated and evaluated for their suitability as fibre reinforcement for composites. The mechanical properties, in particular the tensile strength, are the relevant factors.

Raw wool fibers contain fat, suint, plant material and minerals. It is necessary to remove these from wool by scouring with a combination of detergents, wetting agents and emulsifiers before further processing. Dyeing and finishing of wool fibers is necessary for their application in apparel and also in interior, automotive, smart and technical textiles. Some of the detergents and auxiliaries used in scouring are eco-toxic and some of them are endocrine disruptors. In many countries, wool scouring and dyeing effluents cannot be discharged to watercourses without further treatment by removing color and toxic components. Wool fibers can be given chemical treatments to make them stain-resistant, flame retardant, shrink-resistant, photo-stable and resistant to insect attack. Some of the chemicals under current practice to achieve these functionalities in wool are not eco-friendly and their discharge to water course is limited to the consent limit set by environment agencies. Environmental impact assessment of raw wool production is well studied but to our knowledge no comprehensive study has been carried out around the environmental impact of chemical processing of wool. Like those of other fiber types, the wool textile industries are under intense consumer as well as stakeholder scrutiny. Accreditation schemes now exist to provide reassurance to modern consumers, who want to see that not only are the marketed products safe but also that they are processed sustainably under ethically and environmentally acceptable conditions. Several alternatives to improve the environmental credentials of various chemical processes used for wool will be discussed.

Inter-fibre cohesion is regarded as an important property of assemblies, such as slivers, made of wool or any other fibres, with respect to the processing in carding, drawing (gilling) and spinning. In this paper, the results of the multiple regression analyses, and their validation, are presented to show that a strong relationship exists between the sliver cohesion (measured as sliver tenacity and sliver specific energy-to-break in a long-gauge tensile test) and a combination of the standard wool properties, such as bulk, mean fibre length (Barbe), mean fibre diameter and medullation content, used for the objective blend specification of New Zealand wools for marketing and processing.

Ten greasy Merino wools were compressed to densities over 1250 kg/m3, stored at about 900 kg/m3 for up to 28 months, and processed to top. Compared with control lots, there was the same hauteur, the same or less noil, and an apparently greater top and noil yield. One compressed, long, coarse crossbred wool gave more noil and top with the lower hauteur.

The continuous processing technology of wool slenderizing integrated with biologic enzyme modification is introduced in this paper. Fiber fineness is obviously reduced by this technology, at the same time, wool scales are efficiently removed. Thus, wool quality is also largely enhanced. This provides favorable raw materials for the development of high added value products.

The research presented in this thesis firstly concerns the use of electrochemical techniques to develop approaches to wool processing which have a lower impact on the environment than conventional chemical methods. Wool is a sulfur rich substrate and current methods used in wool processing often rely on sulfur-based reducing agents such as metabisulfite. However, due to increasing concern over the environmental impacts of metabisulfite, alternative methods are of interest. Electrochemical techniques have been applied to the process of wool setting in the presence of thiol setting agents. Wool disulfide bonds are reduced during this process and the thiol setting agent is converted to the disulfide. Efficient conversion of the disulfide back to the thiol setting agent would allow catalytic amounts of thiols to be used in wool setting. The electroreduction of cystine and 2-hydroxyethyl disulfide has been examined at a range of metal and carbon electrodes to find efficient methods of generating the corresponding thiols, cysteine and 2-mercaptoethanol respectively. Gold and silver were identified as the most efficient electrode materials. In industrial wool processing, the use of large-scale metal electrodes is expensive and therefore, high surface area gold and silver nanoparticle electrodes were fabricated by electrochemically depositing the metals onto low-cost carbon substrates. The most efficient electrochemical system for generating the thiol setting agent involved the electroreduction of cystine at the gold nanoparticle electrode and this system was used to successfully demonstrate that wool setting can be achieved using relatively low concentrations of cysteine. Further research was carried out to investigate methods for the controlled preparation of metal nanoparticle electrodes and their utility for detecting hydrogen peroxide was examined. A simple and versatile approach for the preparation of tethered gold nanoparticle assemblies was developed by exploiting electrostatic interactions between citrate-capped gold nanoparticles and amine tether layers attached to carbon surfaces. The nanoparticle assemblies were optimised for the detection of hydrogen peroxide by selecting the size and density of electrostatically assembled nanoparticles. The number of amine functionalities on the surface and the assembly conditions controlled the nanoparticle density. Nanostructured palladium electrodes fabricated using vapour deposition methods to immobilise palladium nanoparticles directly onto carbon substrates were also examined for the electroanalysis of hydrogen peroxide.

Wool scouring is the first stage of wool processing, where unwanted contaminants are removed from freshly shorn wool. In most scouring machines wool is fed as a continuous mat through a series of water-filled scour and rinse bowls which are periodically drained. The purpose of this project is to mathematically model the scour bowl with the aim of improving efficiency. In this thesis four novel models of contaminant concentration within a scour bowl are developed. These are used to investigate the relationships between the operating parameters of the machine and the concentration of contamination within the scour bowl. The models use the advection-diffusion equation to simulate the settling and mixing of contamination. In the first model considered here, the scour bowl is simulated numerically using finite difference methods. Previous models of the scouring process only considered the average steady-state concentration of contamination within the entire scour bowl. This is the first wool scouring model to look at the bowl in two dimensions and to give time dependent results, hence allowing the effect of different drainage patterns to be studied. The second model looks at the important region at the top of the bowl - where the wool and water mix. The governing equations are solved analytically by averaging the concentration vertically assuming the wool layer is thin. Asymptotic analysis on this model reveals some of the fundamental behaviour of the system. The third model considers the same region by solving the governing equations through separation of variables. A fourth, fully two-dimensional, time dependent model was developed and solved using a finite element method. A model of the swelling of grease on the wool fibres is also considered since some grease can only be removed from the fibre once swollen. The swelling is modelled as a Stefan problem, a nonlinear diffusion equation with two moving boundaries, in cylindrical coordinates. Both approximate, analytical and a numerical solutions are found.

This research developed new creative opportunities for textile design by investigating CO2 laser processing technology to achieve surface design and three-dimensional effects. A practice based and interdisciplinary textile design methodology was employed, integrating scientific and technical approaches with a reflective craft practice. It was found that the synthesis of design and science was imperative to achieving the research goal of evolving techniques that have opened new design opportunities for textile design whilst being viable and communicable for industrial and commercial application. Four distinct Laser Textile Design techniques were developed in this research including: a laser enhanced dyeing technique for wool and wool blends; Peri-Dyeing, a laser dye fixation technique; a laser moulding technique; and a laser fading linen technique.

The carbon dioxide (CO2) laser woodcutting has been used as an alternative to traditional wood machining processes. Smaller kerf width and non-contact machining were among the advantages and unique features of laser woodcutting. On the other hand, conventional wood machining such as sawing involves the application of force to separate chips from the workpiece until the desired size of workpiece is achieved. The focus of this research is to study and identify the quality of CO2 laser woodcutting. Various species of Malaysian wood have been used for this study. The initial experiment was carried out by studying the dimensional accuracy and material removal rate which reveals the trend of the laser woodcutting process.

The interest in wood-polymer composites and their use in different applications has been growing over the last 10-15 years. Environmental issues and demands on lower material costs are the driving forces behind the increasing use of renewable materials such as wood and other natural fibres as reinforcement in polymer composites. Wood flour consisting of small wood particles is currently used as the main wood raw material in commercial wood-polymer composites. However, the reinforcing potential of wood flour is limited. A better reinforcement could be achieved by using wood fibres with a higher aspect ratio as raw material, but individual fibres are seldom used in composite manufacturing due to processing problems and high cost. Therefore, the objective of the work was to study the possibility to use wood chips as raw material and separate individual fibres with higher aspect ratios from the wood chips during the composite manufacturing process. First, the effect of the extrusion process only on wood raw material was studied without a matrix polymer, and then composites using polypropylene as matrix were made. The main goal was to produce wood particles/fibres with high aspect ratio during the manufacturing of wood polymer composites. The effects of extrusion parameters, different screw configurations, raw materials and raw material pre-treatments were evaluated. The size of the separated wood particles and fibres was measured using optical fibre analysis methods. Microstructure of wood particles as well as the fractured surfaces of prepared composites were examined using electron microscopy. The mechanical properties of the composites were measured using flexural and impact testing. The results showed that wood chips can be used as raw material in a one-step manufacturing process of wood-polymer composites. Also, individual fibres with a higher aspect ratio than wood flour were separated from the wood chips with suitable processing conditions

Thesis (MScFor (Forest and Wood Science))--University of Stellenbosch, 2009.
ENGLISH ABSTRACT: Wood waste, when used for gasification is commonly pressed into briquettes, especially if no uniform particle size is available. This densification reduces problems of handling, storage and transportation and improves the combustion performance because of a more uniform fuel size. Briquettes have to be mechanically strong enough to be handled. Cohesive strength is provided by residual moisture and lignin present in the wood. The lignin acts as a natural binder. However, the briquetting process becomes more complicated if one wants to add other agricultural waste products that do not necessarily contain lignin as binders,, In this study we have investigated various briquetting process parameters, such as mixing ratios of briquettes containing wood chips, grape skins and chicken litter, moisture content and press time. The aim was to determine the optimum process parameters that allow the production of briquettes, containing a blend of biomaterials that are mechanically stable to allow further handling but yield high energy content at the same time.
AFRIKAANSE OPSOMMING: Wanneer houtafval vir vergassing gebruik word en die partikelgrootte daarvan varieer, word die materiaal normaalweg in ’n brikket gedruk. Brikketvorming vergemaklik opberging, hantering en vervoer. Weens die meer uniforme grootte en vorm van die brikkette is verbranding daarvan heelwat meer doeltreffend. Brikkette moet egter meganies sterk genoeg wees om hanteer te kan word. Die kohesiewe sterkte word deur residuele vog en lignien, wat as natuurlike bindmiddel in hout aanwesig is, verskaf. Indien ander materiale soos landbouafval, wat noodwendig geen lignien bevat nie egter gebruik word, word die brikketvormingsproses meer kompleks. In hierdie ondersoek is verskeie brikketvormingsparameters evalueer. Mengverhoudings van brikkette wat houtspaanders, druiwedoppe en hoendermis bevat, asook invloed van materiaalvoggehalte en druktyd is bestudeer. Die doel was om die optimale materiaal- en prosesparameters vas te stel wanneer ’n mengsel van biomateriale gebruik word om brikkette te lewer wat meganies sterk genoeg is maar steeds die hoogste energieopbrengs lewer.

A classificação da qualidade da madeira é indicada para indústria de processamento e produção desse material. Essas empresas têm investido em soluções para agregar valor à matéria-prima, com o intuito de melhorar resultados, observando os rumos do mercado. O objetivo deste trabalho foi comparar Redes Neurais Convolutivas, um método de aprendizado profundo, na classificação da qualidade de madeira, com outras técnicas tradicionais de Máquinas de aprendizado, como Máquina de Vetores de Suporte, Árvores de Decisão, Regra dos Vizinhos Mais Próximos e Redes Neurais, em conjunto com Descritores de Textura. Isso foi possível através da verificação do nível de acurácia das experiências com diferentes técnicas, como Aprendizado Profundo e Descritores de Textura no processamento de imagens destes objetos. Foi utilizada uma câmera convencional para capturar as 374 amostras de imagem adotadas no experimento, e a base de dados está disponível para consulta. O processamento das imagens passou por algumas fases, após terem sido obtidas, como pré-processamento, segmentação, análise de recursos e classificação. Os métodos de classificação se deram através de Aprendizado Profundo e por meio de técnicas de Aprendizado de Máquinas tradicionais como Máquina de Vetores de Suporte, Árvores de Decisão, Regra dos Vizinhos Mais Próximos e Redes Neurais juntamente com os Descritores de Textura. Os resultados empíricos para o conjunto de dados das imagens da madeira serrada mostraram que o método com Descritores de Textura, independentemente da estratégia empregada, foi muito competitivo quando comparado com as Redes Neurais Convolutivas para todos os experimentos realizados, e até mesmo superou-as para esta aplicação.
The quality classification of wood is prescribed throughout the wood chain industry, particularly those from the processing and manufacturing fields. Those organizations have invested energy and time trying to increase value of basic items, with the purpose of accomplishing better results, in agreement to the market. The objective of this work was to compare Convolutional Neural Network, a deep learning method, for wood quality classification to other traditional Machine Learning techniques, namely Support Vector Machine (SVM), Decision Trees (DT), K-Nearest Neighbors (KNN), and Neural Networks (NN) associated with Texture Descriptors. Some of the possible options were to assess the predictive performance through the experiments with different techniques, Deep Learning and Texture Descriptors, for processing images of this material type. A camera was used to capture the 374 image samples adopted on the experiment, and their database is available for consultation. The images had some stages of processing after they have been acquired, as pre-processing, segmentation, feature analysis, and classification. The classification methods occurred through Deep Learning, more specifically Convolutional Neural Networks - CNN, and using Texture Descriptors with Support Vector Machine, Decision Trees, K-nearest Neighbors and Neural Network. Empirical results for the image dataset showed that the approach using texture descriptor method, regardless of the strategy employed, is very competitive when compared with CNN for all performed experiments, and even overcome it for this application.

This paper provides an analysis of what happens with the sheep wool in Romania. Unfortunately, I found out that most of this “gold mine” is going to export, being processed, and then imported back for a much bigger price. The processing of sheep wool is not a very complicated process. There are processing lines that can take the sheep wool and by the end of the line, you get lanolin and fibers. Besides the very high margin that can be obtained from this type of business, motivation came from the idea of using our country resources at the maximum and try to have some products made in Romania. The main objective of this paper is to analyze the outcomes of a sheep wool processing line and the market in Romania. Sheep wool is a very precious raw material that can provide profit by processing it, having significant margins.

In spinning mills, the optimum correlation between the raw material properties, the yarn's characteristics and the manufacturing technology, is a key point for the production of good quality yarns. Beyond of its significant influence on the yarn characteristics, the raw material determines also the yarns' cost, representing up to 80% of it. Using the blending technique, in which fibres with different properties are combined in order to obtain mixture with average characteristics, it is possible valorising all types of fibres and producing yarns with desired characteristics. In this regard, the yarn designer has to choose the appropriate fibres and setting the right values for blend ratios, in order to obtain the best correlation between the fibres blend properties and the yarn characteristics. The paper presents a software application used as teaching tool for designing the fibre blends. The PFirL software gathers all the information and provides all the tools required for design of the fibre blends in wool spinning mill. It has a modular structure that includes independent procedures; these can be performed individually or in the logical order imposed by the algorithms underlying the program. The software is used to teach the students the principles of rational fibre blend design and to train them in accordance with the requirements of engineering profession. This tool enables the creation and verification of fibre blends in accordance with the yarns destination, mixture composition and manufacturing technology. It evaluates the spinnability of the designed blends and offers useful information for predicting their behaviour during processing, as well about the yarns' characteristics. The software was created with Microsoft Visual Basic and Visual C++ and runs in a Windows environment.

The USDA Caribbean Climate Hub and the State and Private Forestry Program of the International Institute of Tropical Forestry of the US Forest Service, held a workshop on November 21, 2017 where more than 80 people gathered to identify the opportunities and resources necessary to take advantage of the wood from fallen trees in Puerto Rico after hurricanes Irma and Maria. Due to the economic and cultural value of tropical timber species, economic activities can be created from the available posthurricane plant waste. Millions of fallen trees and branches can be processed to produce compost, mulch, coal and biofuels, or raw material for artisans and construction. There is also economic value in the handling of wood materials, the sale of tools and equipment for transporting and processing, and the sale of valuable wood products. In addition, many wood products store carbon indefinitely, mitigating the increase of CO² in the atmosphere. The main need identified during the discussion was the need to act quickly to avoid the burning and disposal of wood materials in landfills across the country.
