Amma yana da rashin kwanciyar hankali na thermal, taushi a 70-80 ℃ da narkewar nakasawa sama da 150 ℃. Hakanan yana da raunin juriyar tsufa kuma yana da saurin lalacewa lokacin amfani da shi a waje ba tare da maganin UV ba. ;

2. Hakuri da Sinadarai da Muhalli

Polyester spunbond yana da kewayon juriya na tsawon lokaci na 260 ℃ da kewayon zafin jiki na ɗan gajeren lokaci na 300 ℃. Yana da juriya ta hanyar sinadarai, juriya acid, kuma mara juriya na alkali, tare da ƙimar ɗaukar danshi na ƙasa da 0.5%. Yana da maganin kashe kwayoyin cuta, hujjar asu, da kuma hujjar mold.

Polypropylene spunbond yana da kewayon juriya na tsawon lokaci na 120 ℃ da kewayon zafin jiki na ɗan gajeren lokaci na 150 ℃. Yana da juriya ga sunadarai, acid, alkalis, da mafi yawan kaushi na kwayoyin halitta, tare da adadin danshi na ≈ 0%. Yana da kyawawan abubuwan sha na asali da abubuwan kashe ƙwayoyin cuta, keɓance yashwar kwayan cuta da samun ingantattun kaddarorin ƙwayoyin cuta.
