【摘要】 为了改善蚕丝纤维的性能,提高真丝制品的附加值,本研究将一种自制的端氨基超支化聚合物（HBP-NH₂）运用到对真丝纤维及织物进行改性预处理中,探索了HBP—NH₂对真丝改性的可行性,为真丝纤维和制品的改性提供理论依据。本文首先用自制的端氨基超支化聚合物（HBP-NH₂）对桑蚕丝纤维进行改性预处理,利用扫描电镜、傅利叶红外光谱、X射线衍射、热分析等现代分析手段,研究了经端氨基超支化聚合物（HBP-NH₂）处理前后蚕丝纤维的结构,发现处理后纤维内部结构呈现β化趋势,相对结晶度和热稳定性均有一定程度提高。经端氨基超支化聚合物（HBP-NH₂）处理的桑蚕丝织物对大肠杆菌和金黄色葡萄球菌均有良好的抑菌作用,另外处理后织物强力略有增强,折皱回复角有所提高,抗皱性增强,织物的吸湿性提高,吸水性也增强。对经端氨基超支化聚合物（HBP-NH₂）处理的桑蚕丝织物进行染色,结果表明,处理后的织物采用活性染料染色,提高了染料的上染性,实现低盐甚至无盐染色,并且处理后的织物染色色牢度和匀染性令人满意;处理后的织物采用酸性染料染色,可以在较低温度下和中性染浴的条件下进行染色,并且染色效果尚佳。研究结果表明:将端氨基超支化聚合物（HBP-NH₂）对真丝材料进行改性预处理,可以提高真丝纤维的热稳定性和部分力学性能,能够改善真丝制品的染色性能、抗菌性能和抗皱性能,为真丝制品的改性研究提供了一条新的途径。更多还原

【Abstract】 For improving the B.mori silk performance and enhancing the silk product attachment value, the B.mori silk was pretreated with an amino-terminated hyper branched polymer（HBP-NH₂） absolution. The feasibility of silk yarn modified with HBP—NH₂ was investigated, which provided theoretical base for modification of B.mori silk fiber and fabric.In the paper, it was used HBP-NH₂ to pre-treat silk fiber. The structures of Bombyx mori silk fiber treated with HBP-NH₂ was studied by Scanning electron microscope（SEM） ,Fourier transform infrared micro spectroscopy （FT-IR）, X-ray diffraction （XRD） and thermal analysis. It was found that the interior structure of the pretreated silk fiber tended to formβ-structure, and the comparative crystallinity and thermal stability increased at the same time.The silk fabric pretreated with HBP-NH₂ absolution has good antibacterial performance against the staphylococcus aureus and bacillus coli. In addition, the breaking strenth and anti-wrinkle ability of treated fabric have enhanced and the moisture absorption and water absorption has also improved after modification.After dyeing the silk fabric pretreated with HBP—NH₂ absolution, the fabric was achieved salt-free and low-salt dyeing with reactive dyes. The dyeing property has improved. The color fastness and leveling properties was also satisfied. The fabric pretreated with HBP-NH₂ was dyeing at lower temperature and neutral dye liquor when dyeing with acid dyes. And the dyeing effect was quite well.The B. mori silk fabric was modified with HBP-NH₂ successfully. When applying the material to B. mori silk fiber, the mechanical performances of the silk fibers improved, as well as thermal properties. The dyeing properties were also content. And the aim of increasing the anti-bacteria performance and anti-wrinkle-resistant performance of B. mori silk was achieved. This paper offered a new for developing novel silk materials.更多还原
