采用聚酯聚醚亲水整理剂DP-1001和DP-9993整理涤纶织物,研究了影响涤纶亲水性和抗静电性的主要因素,以及涤纶上聚酯聚醚整理剂的解吸性能。结果表明,采用整理剂6%(omf),可显著提高涤纶织物的亲水性和抗静电性,且具有良好的耐久性;提高整理温度可增强涤纶的亲水效果,但对抗静电性的影响较小。模拟研究解吸动力学发现,聚酯聚醚的平衡解吸量随着整理温度的升高而增大,而解吸速率常数则呈减小趋势;解吸过程中,大量吸附在涤纶表面、结合力较弱的整理剂先发生解吸,纤维内表层结合力较强的整理剂在中后期发生扩散解吸。 相似文献

涤纶织物存在亲水性差,易产生静电等问题,文中采用石墨烯-Fe_3O_4复合溶液,用于涤纶织物的抗静电整理,探讨了工艺条件对织物抗静电性能的影响,并测试整理后织物的抗静电性、防紫外线性及耐水洗性。结果表明,涤纶织物石墨烯-Fe_3O_4复合溶液抗静电整理最佳工艺为:石墨烯用量0.27 g/L,Fe_3O_4用量3.73 g/L,黏合剂NH-110用量150.00 g/L,轧液率70%;石墨烯-Fe_3O_4复合溶液整理后涤纶织物抗静电效果好,带电量仅为156 C/m~2,赋予了涤纶织物良好的抗静电性,且水洗5次后仍具有良好的抗静电性。 相似文献

以对苯二甲酸二甲酯(DMT)、乙二醇和聚乙二醇(PEG)为原料,通过酯交换、缩聚反应制备聚酯聚醚型共聚物,并应用于涤纶织物亲水整理.研究了PEG分子质量和n(DMT):n(PEG)对共聚物亲水性和耐洗性的影响,采用IR和XRD技术分析了共聚物的结构,采用GPC测定其分子质量.研究结果表明:PEG分子质量及n(DMT):n(PEG)对共聚物的亲水性、耐洗性有较大影响,当PEG平均分子质量为1500,n(DMT):n(PEG)为3.0:1时,共聚物结晶度为34.05%,平均分子质量为15 329,具有较好的亲水性;相应共聚物整理织物的亲水吸湿、抗静电、易去污性能得到显著改善,并具有优良的耐洗性能. 相似文献

由于涤纶长丝、微孔涤纶两种纤维的纤维表面及性能有很大的差别,因此即使同浴染色也会出现色光不一致的现象。本课题通过耐碱性试验,确定了涤纶长丝及微孔涤纶的减量氧漂前处理工艺为:浴比1:30,烧碱浓度6g/L,高温去油剂0.4g/L,在1300C处理20min;为了减小两组分纤维的色差,通过分散染料筛选,确定了使两组份纤维表面得色深度K/S值相对较大,且色差ΔE相对较小、同色性较好的三原色分散染料:JRB兰、JFG黄、JFRB红,并且分别探讨了染料用量、染色时间、染色温度、染色pH值四个因素对涤纶长丝及微孔涤纶纤维染色同色性的影响。 相似文献

In a previous publication we reviewed some of the most critical issues that affect the coloration and properties of cotton-based textiles [R. Shamey and T. Hussain, Textile Progress 37(1/2) (2005) pp. 1–84]. Today, polyester is still widely regarded as an inexpensive and uncomfortable fiber, but this image is slowly beginning to fade with the emergence of polyester luxury fibers. Polyester fibers currently comprise a commanding 77% share of the total worldwide production of the major synthetic fibers [F. Ayfi, 2003–2004 Handbook of Statistics on Man-Made/Synthetic Fibre/Yarn Industry. Part One, Fibre for Better Living, Association of Synthetic Fibre Industry, Mumbai, India, 2004, p. 177]. More than 95% of all polyester fibers manufactured today is based on polyethylene terephthalate. The dyeing properties of polyester fibers are strongly influenced by many of the processing conditions to which each fiber may be subjected during its manufacturing or in subsequent handling. Significant differences in properties of fibers can therefore arise due to their different processing history. Often, the root cause(s) of a problem in the dyed synthetic material can be traced as far back as the manufacturing process. In order to resolve many of the outstanding issues that commonly occur in the dyeing of this important fiber, a comprehensive review of the issues dealing with the manufacturing history as well as fiber processing conditions, including preparation, dyeing, and finishing is warranted. Although some of the underlying problems are related to common causes such as water quality and imperfections in machinery employed, others are specific to the treatment conditions of the fiber. Such conditions include preparation of ingredients, polymerization, fiber and filament processing conditions, as well as heat setting that can cause problems in the coloration of fiber. This summary analysis complements the rich pool of knowledge in this domain and addresses problems in the dyeing of polyester textile materials in various forms. An overview of various textile operations for polyester is given in the beginning. Then, various key steps and critical factors involved in the production of dyed polyester textile materials are described in detail and problems originating at each stage are summarized. 相似文献

采用涤纶工业丝和相应的废弃的涤纶工业丝作混凝土的增强纤维,分别选择纤维的长度为20、30 mm和纤维的掺量为0.5、1.0、1.5 kg/m3,按国标要求制作试样并进行标准养护后,对增强混凝土的抗裂性能、抗压性能、劈裂抗拉性能和弹性模量进行测试和分析,结果表明纤维增强混凝土的上述力学性能均有所改善,试样受力破坏后不碎裂;并且随着纤维长度和掺量的增加,抗压强度和劈裂抗拉强度提高;回收涤纶与新涤纶的情况大体类似,这给废弃涤纶的回收再利用和节约资源、保护环境提供了途径。不论是涤纶还是回收涤纶,长度为30 mm、掺量为1.5 kg/m3的试样表现出最优的力学性能。 相似文献
