A new instrument has been designed to measure the penetration by rubbing of bacteria from cloth contaminated in the nursing of burn patients through fabrics designed for barrier garments. Most fabrics tested dry reduced the transfer of bacteria from the source cloth to about 10%, irrespective of the results of air filter tests, which agrees with mock nursing results. When the fabrics were tested against a wet surface, the transfer of bacteria rapidly reached 100% if the fabrics had a high wettability, but was slower for fabrics with a low wettability. Through closely woven waterproofed cotton, transfer was 5--25%, but increased three- to four-fold after ten launderings, in line with the water absorption. Transfer through plastic-laminated material was less than 1%. The results suggest that barrier garments should be made either of plastic or of recently waterproofed closely woven cotton at points of contact between nurse and patient where the clothes may be wetted by bacteria-containing wound secretions.

The effect of operating clothing on the dispersal of bacterial particles from the wearers was studied in a dispersal chamber. A comparison was made of six gowns as well as four types of trousers. The gowns were of three basic types, namely a conventional cotton type, disposable types made of non-woven fabric and those of the total-body exhaust system (Charnley type). The dispersal chamber could simulate conditions as expected both in down-flow unidirectional ultra-clean systems and in a conventional turbulent plenum-ventilated system. It was found that the disposable gowns would reduce the dispersal rate by about 30% in the simulated conventionally ventilated system and about 65% in the laminar flow system. The total-body exhaust system (Charnley) would reduce the count by 10-fold in the conventional ventilated system and by 66-fold in the laminar-flow system. The poor performance of the gowns in conventionally ventilated systems was caused by the dispersal of bacterial particles from underneath the gown (about 80%). This was not reduced by the disposable gown and only partially by the Charnley type. This small drop would be further decreased in a conventionally ventilated operating-room as only scrubbed staff would wear the gown. In order to overcome this poor performance in conventionally ventilated operating-rooms impervious trousers would be required. Four types were studied and it was demonstrated that those made either from Ventile or non-woven fabric would reduce the bacterial dispersion fourfold. As these tests had been carried out in an artificial environment checks were carried out in the unidirectional-flow operating-room during total-hip arthroplasty. This was done by comparing conventional cotton gowns with non-woven gowns and total-body exhaust gowns. The results showed good correlation between the operating room and the chamber with the non-woven fabric gown but the total-body exhaust system did not perform as well in the operating room (12-fold compared to 66-fold) the difference being possibly due to the contribution from the patient. However, as this comparison was that which would be most open to influence from other variables confidence could be placed on the chamber test results. Values were also obtained for the total number of bacterial particles dispersed by persons during a standard exercise wearing different clothing. This count was dependent on the clothing worn but a median count of between 1000 and 1500 bacterial particles/min. would be expected when conventional clothing was worn, with a range of between 300 and 19,000. This count could be reduced to about 100/min. if a total-body exhaust suit was worn (range 30-400).

The objective of this article is to study cloth and appearance in the Bronze Age based on the evidence from a previously overlooked oak-log coffin find, the Nybøl burial. The textiles have been investigated and our results compared with cloth from four well-known oak-log coffins: Muldbjerg, Trindhøj, and Borum Eshøj graves A and B. Our analysis demonstrates that this burial contained the coarsest cloth on record to date from the Scandinavian Bronze Age, and that it included some cloth items that are not previously known from the above-mentioned graves. The items of clothing the different textiles may have derived from are discussed, as well as the appearance of the deceased in relation to Bronze Age society. We conclude that this burial contained a previously unknown costume type, but that it is a variation of the others rather than an entirely new category. [ABSTRACT FROM AUTHOR]

The aim of this research is to compare the cloth cultures of Europe and Egypt in the Bronze Age and New Kingdom. The comparison focuses on the fourteenth century cal BC and includes four geographically separate areas, including the oak coffin burials of southern Scandinavia, the Hallstatt salt mines of central Europe, Late Minoan Crete, and the tombs and towns of the later Eighteenth Dynasty of Egypt. The comparative approach can bring insights even when applied to unconnected cultures or regions. However, in this study I concentrate on a restricted chronological period and areas that were connected, directly or indirectly, by widespread networks of trade or exchange. The concept of cloth cultures is used to include both textiles and animal skins as these were closely related materials in the prehistoric past. Information was gathered according to the following categories: raw materials, including textile fibre, and species of skins; fabric structure and thread count (only for textiles); decoration and finish; and use and context. From this study, it is possible to recognize the universally shared principles of cloth cultures and the great versatility and creativity in the regional cloth cultures of the Bronze Age.
