Process for making aromatic polyamide fibers of high hydrolytic stability is disclosed. The polyamide is a copolymer including chloroterephthalamide or a blend of homopolymers including one with chloroterephthalamide; and the fibers are dried under tension or heat treated.

Process for making fibers with improved hydrolytic stability

Aromatic polyamide fibers of high hydrolytic stability are disclosed. The polyamide is a copolymer including chloroterephthalamide or a blend of homopolymers including one with chloroterephthalamide; and the fibers are dried under tension or heat treated.

Certain poly[hexamethylene adipamide]-poly[poly-(oxyethylene) adipamide] copolymers which provide soil release to nylon fabrics can be applied from solution directly to a threadline without heat-setting. Aqueous alcoholic solutions of the copolymers are preferred for such application.

Coating composition

Spool and spindle chair

A mitre joint for picture frames and the like, wherein abutting portions of two members have pockets milled therein that are spaced a predetermined distance inwardly from their abutting surfaces. In addition, channels connect the pockets with the abutting surfaces. A foreshortenable fastener comprising a four sided hollow body, having front, back, top and bottom sides, is positioned in the adjacent channels, with the front and back sides positioned in the pockets. The front and back sides are wider than the top and bottom sides, which extend through the channels, and a screw extends through a hole in the top side into threaded engagement with the bottom side to bow the bottom side inwardly when the screw is tightened. This foreshortens the fastener and pulls the mitre joint together.
