| 摘要 |
High performance (high tenacity and modulus) polyethylene fibers are subjected to pressure at elevated temperatures in the absence of a matrix to form articles such as non-woven fabrics and film-like structures, which may be translucent or even transparent. Good fiber adhesion and even fiber deformation to produce a substantially void-free article are achieved, even when molding temperatures are below the approximately 138 DEG C melting temperature of the precursor UHMW polyethylene. Fiber physical properties, and especially high tenacities, are retained even when temperatures exceed 138 DEG C, such as at 140 DEG C, 150 DEG C or 155 DEG C molding temperature. |
