EEC Inter- laboratory Tests on Methods of Analysis of Fibre Mixtures EEC Working Party on Textile Names and Labelling - Analysis

Abstract

With today's global competitive marketplace, new textile product development requires a design, marketing, materials and technology interface. An opportunity existed to examine the new textile product development processes being used by global textile companies with a variety of textile product end-uses: apparel, home textiles, transportation, industrial, nonwovens, carpets, and medical textiles. The Crawford and DiBenedetto model (2003) was used as the conceptual framework for the study and data was collected using secondary and primary data sources. A total of 24 global companies, based in the United States, comprised the sample for this study. Each company's new textile product development processes, practices, and new products were examined, with identification of key new product development concepts being utilized. Results indicated that companies were utilizing new product development (NPD) processes as a competitive tool, but are using a combination of NPD strategies to develop and launch products in the global marketplace.     

Impact properties of thermoplastic composites

The excellent properties exhibited by thermoplastic composites at much reduced weight have attracted attention in the development of products in different sectors. Thermoplastic (TP) composites, because of their distinctive properties as well as ease of manufacturing, have emerged as a competitor against the conventional thermoset resin-based composites. Depending on the application, these composites may undergo impact events at various velocities and often fail in many complex modes. Hence, the development of TP composites having high energy-dissipation at (the desired) much-reduced weight has become a challenging task, but it is a problem which may be alleviated through the appropriate selection of materials and fabrication processes. Furthermore, fibre surface modification has been shown to increase fibre-matrix interfacial adhesion, which can lead to improved impact resistance. Textile preforms are helpful in acting as a structural backbone in the composites since they offer a relatively free hand to the composite designer to tailor its properties to suit a specific application. Additionally, hybrid textile composite structures may help in achieving the desired properties at much lower weight.

Simulation software can play a significant role in the evaluation of composites without damaging physical samples. Once the simulation result has been validated with actual experimental results, it should be possible to predict the test outcomes for different composites, with different characteristics, at different energy levels without conducting further physical tests. Various numerical models have been developed which have to be incorporated into these software tools for better prediction of the result.

In the current issue of Textile Progress, the effects of various materials and test parameters on impact behaviour are critically analyzed. The effect of incorporating high-performance fibres and natural fibres or their hybrid combination on the impact properties of TP composites are also discussed and the essential properties of TP polymers are briefly explained. The effects of fibre and matrix hybridization, environmental factors, various textile preform structures and fibre surface modification treatments on the impact properties of thermoplastic composites are examined in detail. Various numerical models used for impact analysis are discussed and the potential applications of TP composites in automobile, aerospace and medical sectors are highlighted.     

Eco-friendly printing of natural fabrics using natural dyes from alkanet and rhubarb

In the present work, the suitability of printing natural fabrics (wool, silk, cotton and flax) with two natural dyes (alkanet and rhubarb) using pigment-printing technique has been investigated. The effect of different factors, i.e. dye concentration, nature of thickening agent, type of fixation, concentration and type of mordant, has been studied. The printed goods were evaluated by measuring the K/S value and the overall fastness properties. Results show that the highest K/S value was obtained by using Meypro gum as a thickener. The K/S increases rapidly as the concentration of the natural dye powder in the printing paste increases from 10 to 40 g/kg printing paste. Moreover, results show that the printed goods, which were fixed via steaming, have relatively higher colour strength than their corresponding samples fixed via thermofixation. The effect of mordants on colour development was also studied and alkanet dye was chosen as an example for this investigation. The best results were obtained by using mordant at a concentration of 20 g/kg printing paste. Different colour yields could be obtained by using different mordants, and all of colour fastness results were ranging between very well and excellent.

From Part to Whole: Developing an Appreciation of Kuna Molas as Collectibles

Abstract

In the Kuna language the word mola is polysemous, with meanings which include cloth, a rectangular panel of appliquéd cloth and a complete blouse. A pair of mola panels joined together with a yoke and sleeves form a mola blouse, thus the word mola means both part and whole of an item of clothing. Sewn and worn by Kuna women and girls, molas have become identified with Panama and mola panels have become the quintessential tourist souvenir. Parallels are made between the meaning and iconic role of the Kuna mola and art forms from other indigenous cultures. Individual mola panels are found in the collections of major ethnographic, art, and textile museums and there are many private collectors in the US, Europe, Japan and Australia. The role of the mola blouse as part of the dress ensemble of Kuna women is frequently not appreciated, since complete mola blouses form a small part of many collections. The display of mola panels as artworks in ethnographic and art museum exhibitions promotes their intrinsic aesthetic qualities and contributes to distancing them from their role as a component of dress. The meaning of molas may be considered to be polyvalent: Kuna women who sew and wear molas and Kuna communities may derive various meanings; there may be various meanings attributed to specific designs; and outsiders may derive different meanings. The attraction of molas to the Western eye is explored in terms of Kuna ethnoaesthetic principles and choice of iconography, as well as aesthetic appreciation. Molas may be interpreted as early examples of craftivism and contemporary collectors are attracted to their handmade qualities.
