13. Otimização dos parametros de regulagem das maquinas circulares de malharia, utilizando a metodologia Taguchi
Dimensional stability knitted fabrics is a usual problem in apparel industry. In this work, the aim was to find the best set-up of machine in order to achieve a good dimensional stability and elasticity. By using cotton and spandex yarns to build the fabric, the optimisation of the machine parameters was done by the Taguchi s method. Three steps were involve

14. Persistence of Salmonella typhimurium on Fabrics
The persistence of Salmonella typhimurium (V-31) on wool blanket, wool gabardine, cotton sheeting, cotton knit jersey, cotton terry cloth, and cotton wash-and-wear fabrics was studied. Three methods of exposure were employed to contaminate the fabrics: direct contact, aerosol, and a lyophilized mixture of bacteria and dust having a high content of textile fi

15. Factors Affecting the Persistence of Staphylococcus aureus on Fabrics
The persistence of Staphylococcus aureus (Smith) on wool blanket, wool gabardine, cotton sheeting, cotton knit jersey, cotton terry cloth, and cotton wash-and-wear fabrics was studied. The fabrics were exposed to bacterial populations by three methods: direct contact, aerosol, and a lyophilized mixture of bacteria and dust having a high content of textile fi

16. Quantitative Studies on Fabrics as Disseminators of Viruses: I. Persistence of Vaccinia Virus on Cotton and Wool Fabrics
The persistence of vaccinia virus on wool (blanket and gabardine) and cotton (sheeting, terry cloth, and knit jersey) fabrics was studied. The fabrics were exposed to the virus by three methods: direct contact, aerosol, and virus-containing dust having a high content of textile fibers. Fabrics exposed to virus by each method were held in 35 and 78% relative

17. Quantitative Studies on Fabrics as Disseminators of Viruses: II. Persistence of Poliomyelitis Virus on Cotton and Wool Fabrics
The length of time that poliovirus could be recovered from wool gabardine and blanket, and from cotton sheeting, terry cloth, and knit jersey fabrics was determined under conditions of controlled temperature and humidity (25 C in 35 and 78% relative humidities). Three types of exposure of the fabrics to viruses were used: direct contact, aerosol, and virus-c

18. Quantitative Studies on Fabrics as Disseminators of Viruses: V. Effect of Laundering on Poliovirus-Contaminated Fabrics
The effects of laundering with both anionic and nonionic detergents in cold, warm, and hot water on poliovirus-contaminated cotton sheeting, cotton terry cloth, washable wool shirting, wool blanketing, dull nylon jersey, and dacron/cotton shirting were determined. The fabrics were exposed to virus by aerosolization and direct contact (pipette) in separate st

19. Lid Method for Evaluating Zone of Inhibition of Treated Fabrics
Stainless-steel wire cloth lids were found to be advantageous in the evaluation of zones of inhibition with germicide-treated cotton fabrics.

20. Quantitative Studies on Fabrics as Disseminators of Viruses: IV. Virus Transmission by Dry Contact of Fabrics
Cotton and woolen fabrics and fabrics of synthetic fibers were exposed by direct contact (pipette) and by aerosolization to poliovirus and to vaccinia virus in separate experiments, allowed to dry for 16 hr at 25 C in 35% relative humidity, and randomly tumbled with sterile swatches of the same fabrics for 30 min. By use of a HEp-2 cell assay system, up to 1

24. Quantitative Studies on Fabrics as Disseminators of Viruses: III. Persistence of Vaccinia Virus on Fabrics Impregnated with a Virucidal Agent
Eight compounds were tested in vitro for virucidal and antiviral activity against poliovirus and vaccinia virus. These compounds included five quaternary ammonium salts, two bromosalicylanilides, and neomycin sulfate, an antibiotic. None of the compounds was active against poliovirus, but virucidal activity was demonstrated against vaccinia virus with three
