(Received: May 4, 2010; June 10, 2010) Abstract: Textile cardiovascular prostheses are woven or knitted structures made generally from biocompatible polyester fibres. After production, they have to undergo special treatments before packaging such as compaction. This treatment is necessary to reduce porosity especially for knitted structures, but it can modify poly(ethylene terephthalate) (PET) ...

Seven patients exposed to the inhalation of synthetic fibres presented with various bronchopulmonary diseases, such as asthma, extrinsic allergic alveolitis, chronic bronchitis with bronchiectasis, spontaneous pneumothorax, and chronic pneumonia. The histological features are described and an attempt has been made to set up immunological techniques for the diagnosis. A series of histochemical t...

People are special. The importance and need for the research and development into medical and healthcare devices can never be overstated. In the 21st century, medical and healthcare devices play a more vital role in our lives than ever before. A wide range of materials are being used for producing numerous medical and healthcare devices for a variety of end use. In this manuscript, historical d...

The scientific definition of polyethylene terephthalate (PET) changed for polyester in the common language. It was first manufactured 1928 and production fibre version started 1941. Nowadays, 70% artificial textile raw materials are fibres a significant amount plastic waste is generated at end life cycle clothing other products. injection moulding process introduced 1970s made it possible to de...

As a natural protein, silk has a tremendous demand as textile commodity. However, compared to Bombyx mori silk, commonly known as mulberry silk, the other non-mulberry silks have some drawbacks like coarseness, low draping, wash and wear characteristics etc. which can be changed using chemical treatment. In this study, effects of some highly polar, non-polar and bipolar solvents on fibre of mug...

A survey of 255 workers in four cottonseed crushing mills included a respiratory health questionnaire, allergy skin testing, and measurements of lung function over the Monday working shift. Atopy was defined as having two or more positive weal reactions to common inhalant antigens. Categories of exposure to dust were based on the stage of milling, and one category contained workers with continu...

In this paper, we present an industrial problem found in a company that produces acrylic fibres to be used by the textile industry. The problem is a particular case of the discrete lot sizing and scheduling problem (DLSP). In this problem, lots of similar products must be generated and sequenced in ten unrelated parallel machines, in order to minimize tool changeovers and the quantity of fibre ...

Often referred to as the ‘Dutch disease’ economies with resource advantages or specific specialisations can be highly resistant to change and as a result enter a period of absolute decline. These economies, or industries, very specialisation then becomes a barrier to further development when technologies and the world economy evolve. This paper critically examines the impact of this ‘Dutch dise...

One of the dream reactions in polymer chemistry is the bottom-up, self-assembled synthesis of polymer fabrics, with interwoven, one-dimensional fibres of monomolecular thickness forming planar pieces of textiles. We have made a major step towards realizing this goal by assembling sophisticated, quadritopic linkers into surface-mounted metal-organic frameworks. By sandwiching these quadritopic l...
