dc.description.abstractIn this paper, the strength properties of the two groups of sponge cloths available on the market of the Republic of Serbia were investigated. One group of sponge cloths was made of viscose - cotton fiber blend (Samples 1 to 3), while the other group was reinforced with a polyester net (Samples 4 and 5). Strength properties of investigated cloths were determined based on tensile strength, tensile elongation, bursting strength and ball traverse elongation. Investigations were carried out on samples immediately after their removal from commercial packaging (wet samples) and drying on the air (T=30 °C, φ=40%) in the duration of two days (dry samples). The obtained results showed that examined strength properties are in a function of the raw material composition of the sponge cloth and moisture content in the investigated samples, while the tensile strength and tensile elongation are also in a function of the direction of the investigation (machine direction or cross direction). The results of the quality assessment of the investigated sponge cloths, obtained based on the complex criterion of quality, showed that only the sample 3 has good quality, while the other four samples have excellent quality, both in wet and dry condition.en
dc.description.abstractU radu su ispitivana prekidna svojstva dve grupe sunđerastih krpa dostupnih na tržištu Republike Srbije. Jednu grupu su činile sunđeraste krpe dobijene od mešavine viskoze i pamuka (uzorci 1-3), dok je druga grupa obuhvatala krpe ojačane poliestarskom mrežom (uzorci 4 i 5). Od prekidnih svojstava su određivani prekidna sila, prekidno izduženje, sila probijanja i hod kugle pri probijanju. Ispitivanja su realizovana na uzorcima neposredno nakon njihovog vađenja iz komercijalnog pakovanja (mokri uzorci), i sušenja na vazduhu (T=30 °C, φ=40%) u trajanju od dva dana (suvi uzorci). Dobijeni rezultati su pokazali da su ispitivana prekidna svojstva u funkciji sirovinskog sastava krpa i vlažnosti ispitivanih uzoraka, dok su prekidna sila i prekidno izduženje takođe i u funkciji pravca ispitivanja (uzdužni ili poprečni). Rezultati ocene kvaliteta ispitivanih krpa, dobijeni na osnovu kompleksnog koefi cijenta kvaliteta, pokazali su da samo uzorak 3 poseduje dobar kvalitet, dok ostala četiri uzorka imaju odličan kvalitet kako u mokrom, tako i u suvom stanju.sr
