Warp yarns undergo various types of complex stress during the weaving process; namely tensile, cyclic-extension, compression, bending and abrasion. The capacity of the yarns to withstand these stresses is termed as their weavability. The prediction of weavability is exploited to extract first-hand information about the expected performance of yarns in weaving. This critical review article discusses several approaches that are adopted by the researchers for the prediction of warp breakages in weaving; namely, empirical, statistical and instrumental. The recent developments in the field of prediction of warp breakage rate in weaving are summarized. The research work that is currently being pursued in the attachment of a microprocessor based shedding device in a constant tension transport (CTT) instrument for the prediction of the weavability of spun yarns is highlighted.

Discusses the 6th ITCRR, its breadth of textile and clothing research activity, plus the encouragement given to workers in this field and its related areas. States that, within the newer research areas under the microscope of the community involved, technical textiles focuses on new, ‘smart’ garments and the initiatives in this field in both the UK and the international community at large. Covers this subject at length.

The fabric construction of the ballistic fabrics used in military helmets is analyzed in this research and the ballistic performance of the fabric construction is compared. The advanced compact index Ψ_z is used in designing the construction of the ballistic fabrics used for military helmets. There is a relationship between the compact index of the fabric and its ballistic performance when this method is selected. Once the compact level of the fabric is grasped accurately, it raises the distinct thinking that antiballistic fabric design and its weavability in relation to the product performance of antiballistic fabric, gives free rein to get twice the results with half the effort. An effective parameter can then be supplied to a Computer Simulation Design to be used as a reference plan to increase ballistic fabric design. The particularity of national defense products which require reducing costs, raising efficiency, performing effective combat and putting into use quickly is addressed. This is a method to improve the performance of current basic materials.

Polyester filament fabrics made from microdenier and normal denier yarn are compared for their low stress mechanical properties and hand values. Effects of twisting and sizing on microdenier filament fabric are studied. Sizing proves to be the most important process for microdenier multifilament yarn to realise its speciality effect in the fabric made out of this yarn.

Presents the mechanical models of ring, rotor and air‐jet staple yarn formation. The analysis of formation peculiarities has enabled the establishment of differences among them in micro‐ and macrostructure as well as in their mechanical and physical properties. The comparison of yarn and fabric quality parameters will be very valuable for weavers, knitters, garment manufacturers, finishers and designers. Gives productivity, spinability and economic factors for ring spinning, OE‐rotor and air‐jet spinning processes.

ACCORDING to a leading London evening paper, outside “efficiency experts” are parasites. In an Evening News leading article these words appear:

THIS month there will be assembling at Margate the Conference on Automation organised by the Institution of Production Engineers.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

It has been long debated whether the three bottom lines of sustainability (economic, environmental and social) can be achieved simultaneously or whether achieving one adversely affects the others. This paper analyses the economic sustainability of an environmental initiative, namely, effluent treatment plant (ETP), adopted by an Indian textile industry.

Two situations have been considered for the analysis. First, pure economic view with the operating and installed capacities has been considered. Second, combined economic-environmental view using shadow prices of undesirable outputs (biological oxygen demand, chemical oxygen demand, total nitrogen, total phosphorous, etc.) has been analysed.

It has been found that when pure economic view is considered, the net present value (NPV) of the ETP with present operating capacity (10,200 kL/day) is negative, implying that it is not economically sustainable. However, if the ETP is operated with the full installed capacity (17,000 kL/day), it becomes economically sustainable except in the case of very high cost of capital (13%). Finally, when shadow prices of undesirable outputs are considered, the NPV becomes positive, bolstering the economic-environmental sustainability of ETP.

In future, multiple case studies should be conducted in similar organisations to extend the general applicability of the outcome of this study. This research considers the economic and environmental aspects of ETP. However, social benefits have not been considered in this research work, which can definitely be addressed in future endeavours.

Though very high capital investment of ETP acts as a barrier, the results of this study imply that the top management of textile and clothing organisations should look at it from the holistic economic-environmental viewpoint. The use of ETP also leads to social benefits by improving the health of local community and by reducing their hospitalisation, medical expenditure and absenteeism from school and workplace. The outcome of this research may enthuse the entrepreneurs to adopt environmental initiatives.

The paper provides a framework to evaluate the economic feasibility of ETP by considering the time value of money. It is demonstrated with a real case that the environmental initiatives can be economically rewarding.
