An investigation about comfort and protection performances of disposable and reusable surgical gowns by objective and subjective measurements

This study was conducted to investigate comfort and microbial protection performances of two reusable and two disposable surgical gowns by subjective wear trials conducted on eight healthy Dentistry faculty students under environmental conditions suitable for a surgical operation. Protection performances of the gowns were tested by a modified bacterial resistance test. Physiological and psychological data were obtained during wear trials. All objective and subjective results were evaluated in the light of standard physical, mechanical, permeability, and resistance (thermal and water vapor) characteristics of the fabrics. According to the results, thermal comfort performance of the woven gown produced from microfiber polyester was the best according to subjective wear trial and microbial resistance test results. Disposable nonwoven gowns had lower comfort performances despite their higher permeability and lower resistance values. Moreover, chest skin temperature, arm microclimate temperature, and arm relative humidity are the physiological parameters significantly correlated with subjective comfort evaluation results.     

Modeling the effect of weave structure and fabric thread density on the barrier effectiveness of woven surgical gowns

Surgical gowns are the shielding cloths worn by the surgical team throughout a surgery to save them from blood pathogens of the patient being operated, and to avoid bacterial infections. Barrier effectiveness of a fabric depends upon the liquid penetration resistance and pathogen resistance of the fabric. The objective of this study was to analyze the effect of different weave structures and fabric thread densities on the barrier effectiveness of the woven surgical gowns. Twelve fabric samples were produced using three different weave structures, i.e. 1/1 plain, 2/2 z-twill, and 3/3 z-twill, and four different fabric constructions and then completed with a water repellent finish. Water repellency spray test and air permeability test were conducted on each of the 12 woven samples. The results of fabric samples were analyzed in Minitab statistical software. The coefficients of determinations (R² values) of the regression equations show good prediction ability of the developed statistical models. The findings of the study may be helpful in deciding appropriate manufacturing specifications of surgical gowns to attain maximum barrier effectiveness.

Establishing thermal comfort: characterization of selected performance and physical properties of fabrics used in hospital operating room uniforms

The purpose of this research was to characterize selected thermal properties of clothing fabrics available to operating room (OR) workers at the University of Alberta Hospital and to relate the thermal properties to fabric structural characteristics. In this study, we measured the thermal resistance and air permeability of fabrics obtained from surgical gowns, scrubs and warm-up jackets currently in use in ORs in a specific hospital. The results showed that the fabrics from which the surgical gowns were made provide the highest thermal insulation with lowest air permeability, while the warm-up jackets’ fabrics had the greatest air permeability with low thermal insulation values. The clothing options available to workers in the OR fall well below the predicted clothing insulation values for thermal comfort. For workers in the OR, such as anaesthesiologists, who are predominantly sedentary throughout their work shift, the lack of thermally insulating clothing options has consequences for their overall thermal comfort. This study comprises part of a larger ongoing study investigating improving the OR workers thermal comfort through clothing.

The effect of pre‐wetting on liquid penetration performance of surgical gown fabrics

This paper presents the results of a study to explore the effects of pre‐wetting of the inner and outer surface of surgical gown materials on their resistance to subsequent penetration. Two gown fabrics currently in common use, one disposable and one reusable, were tested for liquid penetration following standard procedures specified for categorizing surgical gown protection levels. Synthetic blood, simulated human perspiration, and isopropyl alcohols were used as challenge liquids. Significant results from independent‐samples t‐test analysis indicated that the dry–wet condition of surgical gown fabrics is a significant factor in barrier efficacy. Protection of the wearer may be compromised by gown fabric wetness from blood or other liquids in the surgical environment or by the wearer’s perspiration. Protocols for replacement of surgical gowns may need to take these factors into account.     

Reusables win a battle over disposables

The time is right to market the environmental benefits of reusable textiles. Take it from Stan Wiener, director of sales for Unitex Textile Rental Services, Mount Vernon, N.Y. Wearing one of his company's reusable cloth examination gowns, Wiener made a sales call to a leading New York health services center. Persuaded by the environmental friendliness of reusables, the health center made the switch from paper gowns and has realized a 5,000-lb. reduction in disposable trash.     

Multi-response optimization of thermophysiological comfort properties of polyester filament woven fabrics

Microfilament woven fabrics are used in many products such as sportswear, rainclothes, windproof clothes, sleeping bags and surgical gowns and for these products, thermophysiological comfort properties are of prime importance. In this study, it is intended to investigate the effects of filament linear density and weft sett on thermophysiological comfort properties. Also, an optimization model was developed to determine the optimum filament linear density and weft sett for the best response variables of air permeability, water vapour permeability and thermal resistance. Four different weft sett and five different filament linear densities were applied in weft direction with three different weave types. In doing so, 60 woven fabric samples were produced. According to ANOVA results and experimental observations, it is observed that, the effect of filament linear density on air and water vapour permeability was minor on microfilament range, whereas the differences between conventional filament and microfilament sample groups are considerable. Also, higher weft sett causes decreasing of air and water vapour permeability. On the other hand, there is no obvious consistent trend for thermal resistance of samples with different filament linear density and weft sett.
