- Abstract
An investigation of the influence of the contents of original and modified attapulgite (ATP) on the ultradrawing properties of ultrahigh-molecular-weight polyethylene (UHMWPE)/ATP (FA x) and UHMWPE/modified ATP (FAm x) as-prepared fibers is reported. Similar to what is found for the orientation factor values, the achievable draw ratios ( Dra) of the FA x and FAm x as-prepared fibers approach a maximum value as the original ATP and/or modified ATP contents reach their corresponding optimum values. The maximum Dra value obtained for FAm x as-prepared fiber specimens is significantly higher than that for FA x as-prepared fiber specimens prepared at the optimum original ATP content. Similar to what is found for the orientation factors and achievable drawing properties, the tensile strength (σf) and initial modulus ( E) of both drawn F2A x and F2Am x fiber series specimens with a fixed draw ratio reach maximum values as the original and/or modified ATP contents approach the optimum values, respectively. The σf and E values of the F2Am x fiber specimens are always significantly higher than those of the corresponding F2A x fiber specimens prepared at the same draw ratios and ATP contents but without being modified. To understand the interesting ultradrawing, orientation and tensile properties of FA x and FAm x fiber specimens, Fourier transform infrared spectral, specific surface area, transmission electron microscopic and elemental analyses of the original and modified ATPs were performed.
