Explanation of the Invention\n\nThis invention relates to a manufacturing method for po1y-capramide fibers.  In more detail,this relates to a manuf acturingmethod for inexpensive polycapramide fibers,wherein polycapramideis melt-extruded,cooled by passing through a slanted cascade ofwater,and wound.  \nThe method is widely known,wherein polycapramide is melted,the molten material is extruded through spinnerets,the filamentsare cooled to form viable fibers.  Usual1y,the fiber formationprocess is divided into two stages.  The two-process method,com-prised of the spinning process and the drawing process,and theone-process method,wherein these processes are effected continu-ously,are known.  Nonetheless,in_either of these methods,themanufacturing costs are high,and [the methods]are not advan-tageous.  On the one hand,as a method for the further simplifi-cation of the one-process method,the method(Japanese Patent  \nDigitized by the Internet Archivein 2016  \nhttps://archive.org/details/manufacturingmet00iwak  \nTokuko 38-2016(1963,Examined))has been proposed,whereintension is imparted to the filaments by using a perpendicularliquid bath.  In this method,a high takeup rate is necessary.Moreover,because_a perpendicular liquid bath is used,it is nec-essary,for example,to take measures to deal with the leakage ofthe liquid.  This method is not viable because the number ofinstallations multiplies.  \nThis invention differs from these manufacturing methods forpolycapramide fibers.It proposes an extremely inexpensive andviable method for the manufacture of polycapramide fibers.  \nThis invention is explained by figures.  \nPolycapramide is extruded through a spinneret grouping 2,arranged in a line on the spinning package 1.Filament 3 isformed.  Before the filament coagulates,it is made to come intocontact with overf1ow water pipe 4.There after,the filament issent along slanted plate 5 to guide 6.On top of the slantedplate 5,  the water f1owing out of the water pipe 4 forms acascade,and falls into liquid tank 9 at the 1ower section ofthe slanted plate 5.After water is shaken off to some extentwith guide 6,  the filament is guided to roller 7,  which  \nrotates at constant speed.Thereafter,the filament is rolled upby the winder 8.  In the liquid tank 9,  aqueous solution 10is present;the liquid is sent up to water pipe 4 by pump 11.  \nThe rotating roller 7,as required,can be used to effectheat treatment.  \nA1so,by the appropriate selection of the composition ofliquid tank 9,it is possible to apply a lubricating finish tothe surface of the polycapramide fiber.  \nCrimping is conferred on the po1ycapramide fiber obtained inthis way,by using a crimping unit of the stuffer box type:Thesefibers are particu1arly usefu¹as fibers used in interior decorat-ing.  The fibers obtained by this method have the characteristicthat dyeability is extremely improved in comparison to fibersmanu factured by the usual two-process method or the continuousprocess method.  \nThe spinnerets in this invention are desirably spinneretswhich have orifices arranged in a line.When the extrusion ori-fices are arranged in the form of circles or squares,the extrudedfilaments adhere on top of the slanted plate.Therefore,it be","cbCaisdQwLIYQNyM","https://ap.wps.com/l/cbCaisdQwLIYQNyM","pdf",336974,14,"English","## Brief Explanation of the Figure\n## Detailed Explanation of the Invention\n## Actual Example\n## Claims","[{\"question\":\"How are polycapramide filaments formed in this manufacturing method?\",\"answer\":\"Polycapramide is melt-extruded through spinnerets with fine orifices arranged in a line to form filaments.\"},{\"question\":\"How does the method cool and guide the filaments?\",\"answer\":\"Before the filaments coagulate, they contact an overflow water pipe, then move along a slanted plate where flowing water forms a cascade into a liquid tank.\"},{\"question\":\"What advantages are claimed regarding fiber performance?\",\"answer\":\"The method enables very improved dyeability versus fibers made by the usual two-process or continuous processes, and the winding speed can be selected appropriately for the target fiber type.\"}]","MANUFACTURING METHOD FOR POLYCAPRAMIDE FIBERS - Brief Explanation of the Invention | PDF",1789970856,35]
