Abstract The study material consisted of two models protective firefighter footwear. tests were conducted on subjects in a laboratory using an ergometric treadmill. parameters footwear microclimate continuously recorded T/RH sensors. For the leather footwear, highest foot temperature was 50th minute experiment (35.8°C dorsal region and 37.3°C plantar region) for polymer 60th (35.4°C 37.0°C region). In air surrounding feet rose from 31.0°C to 35.4°C, then declined, but did not return initial...

The aim of the study was to produce new elastomeric materials containing butyl rubber (IIR) filled with silica and phyllosilicates (vermiculite, montmorillonite, perlite or halloysite tubes) enhanced hydrophobicity barrier properties reduced chemical degradation. It found that filler type had a significant impact on degree cross-linking its vulcanizates. highest mechanical strength were achieved for IIR composites Arsil tubes. surface (119°) confirmed vulcanizates montmorillonite. All tested...

The objective of the study was to examine mechanical and electrostatic properties poly(vinyl chloride) intended for use in protective footwear. material made with graphite (flake side dimensions 5 10 µm) additive weight concentration variants from 0.5 10.0%. influence incorporating polymer matrix evaluated by testing parameters (according Standard No. EN ISO 20344:2021). In addition, surface morphology, analysis thermal stability were evaluated. results indicated highest increase tear...

The aim of this study was to characterize modified basalt fabrics as semi-finished articles for application in personal protective equipment (PPE), i.e. gloves. Resistance the thermal properties three made fibers differed aspect mass per square meter and thickness well aluminized modifications presented. were obtained by gluing aluminum foil fabric with two kinds glue. results measurements are presented form tables figures. focused on elaboration optimal textile modification designed use...

We propose a new approach to assessing comfort of use protective footwear with textile liner. All-rubber wool liner and cotton/polyamide socks were evaluated in study involving 30 firefighters. The was designed comprehensively assess textiles the using certain known research tools at same time, that is, measurement microclimate inside (temperature humidity), weight gain footwear, socks, (weighing method), blood flows lower extremities (impedance plethysmography), as well evaluation user...

Abstract The paper discusses the methods of modification melt-blown polymer materials by addition a bactericidal agent or superabsorbent directly to fibre-forming area during production process. It also presents tests textile composites designed for use in selected types personal protective equipment worn workplace. One example application is footwear insole. insole contain specially developed variants nonwovens made from PP, PC, and PA fibres. Microbiological, hygienic, mechanical have...

The aim of this study was to evaluate the microstructural changes on surface glove materials used in workplace — new and subject mechanical chemical interactions both simulated conditions a laboratory actual jobs. introductory part presents brief review concerning application scanning electron microscope technique characterize phenomena occurring textiles construct protective gloves. Research has indicated that can be exposed harmful factors. Based results, it found impact proposed different...

Abstract In protecting themselves against different dangerous and noxious factors at the workplace, workers are often faced with necessity of using footwear that puts a significant strain on human body. Such is frequently not accepted by users due to wearing discomfort difficulties performing one’s tasks efficiently. The paper describes requirements concerning evaluation protective functionality hygiene as well formulates recommendations for improvement these properties. Based own studies it...

Our research material comprised antivandal fire-retardant hybrid composites modified with inorganic and organic fillers intended for application in public transport vehicles. This paper presents an approach to studying their impact strength as a function of the composite thickness (3 6 mm) striker shape (hemispherical, semicylindrical, wedge-shaped) used experimental stand. Group A composites, made single fabric layers (n = 5), were thinner was lower by 73% than that B double layers. Study...

Despite the fact that mineral oils are commonly used in industry, they pose a serious health hazard for workers who exposed to them due their sensitizing and carcinogenic properties. Health protection contact with these substances requires, addition collective means of protection, personal protective equipment such as gloves. This paper presents current state knowledge concerning permeation other water-insoluble or non-volatile through polymer membranes clothing gloves, based on literature...

Abstract Foot slippage is the most widespread unforeseen event causing falls on same level, and a potentially contributing factor to from height lower level. Statistical data number of slip-related accidents at work show importance problem slipping indicate need continuously improve preventive measures designed reduce injuries related slipping, tripping, falling (STF) It therefore necessary insightfully analyze causes undertake efforts eliminate occurrence slip- trip-induced workplace...

Abstract The objective of the work was preliminary experimental investigation cut-resistant materials including a biomimetic perspective. effects cutting were expressed as static and dynamic cut resistance following materials: knitted fabrics, woven continuously coated dot-coated fabrics. process gives rise to frictional forces, but current test methods for gloves are not designed measure them. Therefore additionally, material evaluated using modified procedure based on standard EN 1082-1,...

In the environment where glove material is exposed to harmful chemicals, hazards related faster penetration of dangerous substances into interior may cause microdamage. One solutions overcome this problem use self-healing polymeric materials that can minimize economic loss and accidents in workplace. The current work aims present impact different types textile reinforcement on effectiveness efficiency process methyl vinyl silicone rubber containing hybrid molecules with an inorganic...

The objective of the present work was to evaluate effects different types particles added a polymer paste applied onto textile carrier on cut resistance resulting material. Knitted aramid samples were coated in laboratory conditions using that functionalized with 12 reinforcing chemical compositions and size fractions. Cut tested accordance standard EN ISO 13997:1999 results subjected statistical analysis. additive microstructure polymeric layer assessed by means scanning electron...
