A primary study of the number and type of microorganisms in a Thai textile factory.

Personal air samples of different sections inside and outside the factory were collected from July to November of 1981. The number of airborne microorganisms were as follows: blowing section, 337.8; carding section, 247.4; drawing section, 107.8; spinning section, 20.4, and outside the factory, 20.2. The types of bacteria found were classified into three groups: cocci-Gram positive, rod-Gram positive; and rod-Gram negative. The type of fungi were Penicilium sp., Rhizopus sp., Aspergillus sp., and Mucor sp.

Large scale dielectrophoretic construction of biofilms using textile technology.

Arrays of microelectrodes for AC electrokinetic experiments were fabricated by weaving together stainless steel wires (weft) and flexible polyester yarn (warp) in a plain weave pattern. The cloth produced can be used to collect cells in low conductivity media by dielectrophoresis (DEP). The construction of model biofilms consisting of a yeast layer on top of a layer of M. luteus is demonstrated, using polyethylenimine (PEI) as the flocculating agent. This technique offers an alternative to the formation of biofilms at microelectrodes made by photolithography, and would allow the construction of biofilms with defined internal architectures by DEP at much larger scales than was possible previously. Furthermore, the flexibility of the cloth would also allow it to be distorted or folded into various shapes.

Relationship between eye and skin irritation in rabbits using a series of textile fiber finishes.

A series of 76 fiber finishes, typically composed of blends of lubricants, emulsifiers, antistatic agents and fatty acid soaps, were tested in rabbits to determine both the eye and the skin irritation potential. Each finish was classified as being either non-, slightly, mildly, moderately or severely irritating to the target tissue during a 48-h post-treatment period. Seven (9.2%) of the finishes tested were severely irritating to both the skin and the eye; two (2.6%) were determined to be non-irritating to both tissues. While occasionally finishes produced equal degrees of damage resulting in similar irritancy classifications, seven (9.2%) finishes were found to be severely irritating to the skin without producing any irritation in the eye. Conversely, one finish was found to be a severe eye irritant without producing any skin irritation. The suggested use of the skin irritation data to predict the ocular reaction needs to be carefully examined, particularly with materials such as these fiber finishes. The prediction that a severe skin irritant is also a severe eye irritant was demonstrated to be in error with 8 of 75 (10.5%) of the finishes studied. Further, there is little predictive association between the skin and eye irritation for these compounds.

Byssinosis: environmental and respiratory symptoms among textile workers in Sudan.

This study has been carried out to investigate the prevalence of byssinosis and other respiratory symptoms among 311 Sudanese workers in different sections of the Khartoum Weaving and Spinning Company. The prevalence of byssinosis was 67% among blowers, 40% in carders and draw-frame workers, 42% in simplex workers and 37% in ring-frame workers. The prevalence of chronic bronchitis ranged between 29 to 47% in all groups. A significant fall in FEV1 was recorded in carders and draw- and ring-frame workers. There was also a statistically significant decrease in FVC after shift in all groups except in the ring-frame group. The result of the present study revealed that the prevalence of byssinosis was very high in mills processing coarse cotton. Application of control measures and the early detection of exposure effects will reduce the prevalence of byssinosis and other respiratory impairments.

Demonstration of amyloid with Mesitol WLS-Congo Red: application of a textile auxiliary to histochemistry.

Previous histochemical investigations demonstrated similarities in the binding of Congo Red and other direct cotton dyes by amyloid and cellulose. It seemed therefore of interest to determine whether or not the cellulose-like reactivity of amyloid extends also to dye solutions containing an anionic reserving agent. These reagents are used in the dyeing of wool-cellulose (Halbwolle) fabrics to prevent binding of direct cotton dyes by proteins. Mesitol WLS-Congo Red solutions stained amyloid selectively; other tissue structures, except some hyaline deposits in arterioles, remained unstained. The cause of this non-specific reaction could not be determined with certainty. Therefore, the alkaline Congo Red method is recommended for histochemical identification of amyloid. However, the Mesitol WLS-Congo Red technic was very useful for demonstration of amyloid after prolonged storage of tissues in formalin; amyloid in such material showed little or no reactivity with the alkaline Congo Red or the Sirius dye methods. This pilot study indicates that anionic reserving agents can be effectively employed under conditions of histochemical technics.

[Ergonomic analysis of heavy work carried out by female workers in the textile industry].

Work and recovery pulse were measured with 22 female workers doing heavy work. The proposed limit of capacity under continuous operating conditions of 25 work pulses was surpassed by 10 of the 22 workers. Recovery pulse made it possible to detect illness in two cases and correlates significantly with the total duration of relaxing operation. Similar results could not be obtained with work pulse. As the recovery pulse is quickly and easily measurable, it was in the frame of this study a more interesting value than the work pulse.

Comparison of static and shake culture in the decolorization of textile dyes and dye effluents by Phanerochaete chrysoporium.

Decolorization of several dyes (Red HE-8B, Malachite Green, Navy Blue HE-2R, Magenta, Crystal Violet) and an industrial effluent with growing cells of Phanerochaete chrysosporium in shake and static culture was demonstrated. All the dyes and the industrial effluent were decolorized to some extent with varying percentages of decolorization (20-100%). The rate of decolorization was very rapid with Red HE-8B, an industrial dye. Decolorization rates for all the dyes in static condition were found to be less than the shake culture and also dependent on biomass concentration.
