| Résumé : |
Manufacturing of blend man-made fibers especially from polyolefins due to their new and expanded applications has attracted the researchers and technologists' attention. In this study, PP/LDPE blend filament yarn samples with various ratios of 100/0, 99/1, 97/3, 95/5, 93/7, 90/10 were melt spun and then drawn under industrial conditions. According to the results of the melt spinning process, convenient spinnability comparing to pure PP for various polyblend samples up to 10 wt.% of LDPE was observed. Results of microstructure measurements in both group i.e. as-spun and drawn samples showed that the presence of LDPE in blend samples did not deteriorate the density and crystallinity of PP. However, increasing the fraction of LDPE in blend gave rise to noticeable increase in the shrinkage values of drawn samples in comparing to pure PP. Although the tenacity of as-spun and drawn yarns displayed a downward trend by increasing the LDPE in blend, the obtained values for tenacity are still at an acceptable level for further processing or textile applications. |
