Abstract:

In order to improve the added value of visscose fiber, viscose fiber modified by methanol protein was prepared by blending methanol protein and viscose concentrate, and its structure and performance were investigated by means of kjeldahl nitrogen determination apparatus, infrared spectra (IR), scanning electron microscopy (SEM), X-ray diffraction (XRD) and fiber mechanical properties experimental methods. The results show that compared with ordinary viscose fiber, the crystallinity of the methanol protein modified viscose fiber decreased, cross section abnormity degree slightly lowerde, zigzag trend abate, burnish is slightly darker, fiber fracture strength is reduced, and the elongation at break decreased. The fiber shows characteristics of protein fiber and it can be viewed from the infrared spectrum of the fiber and fiber nitrogen content test results that methanol protein modified of viscose fiber has been a successfully prepaerd.
