Side‐by‐side bicomponent meltblown fiber webs were developed on REICOFIL® bicomponent (bico) meltblown line at The University of Tennessee's Textiles and Nonwovens Development Center (TANDEC), using polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), polytrimethylene terephthalate (PTT), and so forth. The posttreatment was performed by hydroentanglement to investigate the fiber‐splitting behavior in this research. Microscopy analysis and SEM were applied to examine the web structure. The change in web property after posttreatment and the adhesion mechanism of the polymer interface were also addressed. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 2090–2094, 2004 相似文献

An investigation of fiber splitting of bicomponent meltblown/microfiber nonwovens by water treatment
Meltblowing is a most versatile and cost‐effective process commercially available worldwide to produce microfiber nonwovens directly from thermoplastic resins. The new bicomponent (bico) meltblown technology opens a great possibility to make even finer microfibers by subsequently fiber splitting. Water‐dispersive Eastman AQ polymers were initially introduced to the meltblown process to make the mono‐ and bicomponent meltblown webs at Textiles and Nonwovens Development Center (TANDEC), University of Tennessee, Knoxville. The postwater treatment was performed on the fabrics, which resulted in the dispersive part (AQ polymer) being dispersed in water and only the other part remaining in the bico web. A process–structure–property study is provided toward the research reported in this article. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 94: 1218–1226, 2004 相似文献

The bicomponent meltblown process offers to associate two polymers in the same fiber generating fibrous media with new properties. In this study, we associate polypropylene (PP) and poly(lactic acid) (PLA), from renewable sources, polymers. The influence of primary air flow rate and the structural properties of the PP/PLA bicomponent meltblown are compared to PP and PLA monocomponent meltblown. The structural properties include fiber morphology and diameter, packing density, permeability, thermal shrinkage and crystallization. The results relate that the PP/PLA bicomponent meltblown fiber diameters are thinner than those of PLA monocomponent. Moreover, it has higher resistance to thermal shrinkage compared to PP monocomponent meltblown. The packing density and permeability are not affected by the association of PP and PLA due to low crimp effect. Two different filament formations of PP/PLA bicomponent meltblown at low and high primary air flow rate have also been observed. Lastly, this study illustrates that PP and PLA association is viable, showing the production of PP/PLA bicomponent microfiber and limited thermal shrinkage at high temperature. © 2016 Wiley Periodicals, Inc.

The results of this study are related to the implementation of the concept of self-reinforced composites. The input materials in preparation process were the bicomponent fibers. The studies were carried out on three types of fibers, HDPE/PP, cPP/PP, LPET/PET. In each case, the matrix material was a low melting polymer, and the core was made of a higher melting point polymer. The research was conducted for the materials shaped by an injection-molding technique. The analyses confirmed the two-component structure. Properties of the resulting composites confirmed the applicability of bicomponent fibers in the preparation of self-reinforced composites. 相似文献

PET/PTT复合纤维卷缩性能的研究 总被引:5,自引:3,他引:2
通过对不同线密度的聚对苯二甲酸乙二醇酯/聚对苯二甲酸丙二醇酯(PET/PTT)复合纤维的热收缩率、卷曲收缩率、卷曲模量及卷曲稳定度的测试,研究了干热和沸水处理条件下的PET/PTT复合纤维的卷缩性能。结果表明:干热处理时,PET/PTT复合纤维的热收缩率随温度的升高而升高,随线密度的提高而减小;与干热处理比较,沸水加压处理后的纤维具有较好的热收缩率和卷曲性能。PET/PTT复合纤维线密度越低,其卷曲收缩能力越强,线密度为172 dtex时,纤维表现出较好的卷曲收缩率和卷曲稳定性。 相似文献
