    Abstract: A new, pulp-like, acrylic short fiber having excellent heat- and chemical-resistance is provided. The fiber has a thickness distribution of 0.1 .mu.m to 50 .mu.m, a length distribution of 1 mm to 20 mm, and a thermal transition temperature (Tg) of above 200.degree. C. The fiber is produced by heating a mixture of polyacrylonitrile and water of about 5% to 100% by weight to temperatures above hydration-melting temperature under seal to an amorphous melt; cooling the resulting amorphous melt to temperatures between the melting and the solidifying temperatures of the melt to form a supercooled melt; extruding the resulting supercooled melt to give extrudates; heat-stabilizing the resulting extrudates at temperatures between 180.degree. C. and 300.degree. C. for 1 minute to 4 hours after drying and drawing; and cutting and beating the resulting heat-stabilized extrudates into an appropriate size.

    Abstract: Provided is a process for making a paper based product which comprises first preparing a slurry of a cellulosic pulp, a particulate binder substantially insoluble in water, and an emulsion comprised of lecithin and a fatty acid or derivative thereof. This slurry is then drained of liquid to form a web, with the web being dried to provide the paper based product. The preferred polymeric binder is a hydrolyzed polyvinyl alcohol powder, which binder can be present in the final dried product in amounts of up to about 20 weight percent or more. The use of the emulsion comprised of lecithin and a fatty acid or derivative thereof permits a web containing such a high amount of sticky polymeric binder to be dried at high temperatures, without the web sticking to the drying cans generally used in commercial processes. The process of the present invention thereby permits one to efficiently prepare such a paper based product using conventional, commercial papermaking machinery.

    Abstract translation: 提供了一种制造纸基产品的方法，其包括首先制备纤维素纸浆，基本上不溶于水的颗粒粘合剂和由卵磷脂和脂肪酸或其衍生物组成的乳液。 然后将该浆液排出液体以形成幅材，将幅材干燥以提供基于纸的产品。 优选的聚合物粘合剂是水解的聚乙烯醇粉末，该粘合剂可以以最多约20重量％或更多的量存在于最终干燥产品中。 使用由卵磷脂和脂肪酸或其衍生物组成的乳液可以使含有如此大量粘性聚合物粘合剂的纤维网在高温下干燥，而不会使网粘附在通常用于商业过程的干燥罐上。 因此，本发明的方法允许使用常规的商业造纸机器有效地制备这种纸基产品。
