COMPOSITE WEB AND PROCESS FOR MANUFACTURE FROM POST-INDUSTRIAL SCRAP |
摘要 |
<p>A composite web and process for manufacture from post-industrial scrap wherein the fibers are pre-opened and cut to an average fiber length of about 4 mm. A scrap fiber component and a cellulosic component of such fibers are blended into a fiber furnish. The scrap fiber component includes at least 15% synthetic fibers and may include a blend of natural fibers, high melting point synthetic fibers, and low melting point synthetic fibers. The cellulosic component may include post-industrial cotton fibers which may be refined before blending with the scrap fiber component. The fiber furnish is processed into an intermediate web such as by a drylaid or a wetlaid nonwoven process. The intermediate web is saturated with a latex binding agent and pressed and/or dried to form a composite web capable of further processing into molded or formed consumer or industrial products. The process is capable of producing a high basis weight composite web.</p> |
