| Abstract: | Conclusions The PE content of a matrix-fibrillar yarn spun from a melt of a PCA-PE mixture exerts a significant effect on the formation of defects in this yarn.Yarn defectiveness has been evaluated from acid-resistance; the latter is somewhat reduced for untexturized yarns (as compared with the acid-resistance of yarns from pure PCA) and is considerably reduced for texturized specimens.During the texturizing process, defects of various depths and lengths are formed on the surface of matrix-fibrillar yarns due to breaking off of individual PE fibrils; the intensity of this phenomenon rises with increase in the concentration of PE in the PCA.Translated from Khimicheskie Volokna, No. 6, pp. 45–46, November–December, 1986. |
