CURED PHENOL-FORMALDEHYDE FIBERS AND METHOD FOR THE PRODUCTION THEREOF
摘要
<p>A new method for the production of phenol-formaldehyde fibres is described. By carrying out this method curing time is shortened and white fibers are obtained directly. The method comprises melt-spinning a resin composition obtained by blending a thermoplastic phenol-formaldehyde type resin with tetrsoxymethylene and/or trioxane and curing the obtained uncured resin fiber in the presence of a acid catalyst.</p>
