摘要
对大豆蛋白质纤维 (PVA SPF)的聚集态结构进行了研究 ,认为聚乙烯大分子呈平面锯齿形构象 ,而大豆蛋白大分子在纺丝前的处理过程中已经变性 ,由α 螺旋转变为直线形的 β 链构象 ,并共同砌入纤维 ;由于二组分大分子均带有较多的极性基团 ,在大分子之间可能形成多种键合 ,同时PVA SPF成纤后进行的缩醛化处理在二组分大分子之间形成了化学交联 ,故而可以认为PVA SPF的聚集态结构是以直链形大分子网状结构为主体的聚集态结构。X 射线衍射图表明 ,PVA SPF大分子的结晶能力较弱 ,二维空间排列有序的向列结晶能力较强。
Studied the polymeric structure of the soybean\|protein fiber (PVA-SPF), the po ly ethylene macromolecule appeared as plane sawtooth configuration,however the soyb ean\|protein macromolecule has been modified from α-helical structure to β-c h ain configuration during spinning preparation;because there are a number of p olar groups on the both the polyethylene and the soybean protein macromolecule.A mong the macromolecules, diversiform bonds can been formed.In addition,the acet alizagio n of the PVA-SPF may form crosslinking between the polyethylene and the soybean protein,so the polymeric structure of the PVA-SPF is a kind of chain reticular structure.And the X-ray diffraction analysis shows that the crystallizing powe r of the PVA-SPF macromolecular is weak,while the ability forming the nematic s tructure is powerful.
