Claims\n\n1.  A process for the manufacture of fibers with latentcurling-shrinking characteristics characterized by the fact thatmultiple pairs of spinning holes with pair-hole diameter ratiosof1.5-2.5 are provided on a spinning clasp,and the spinninghole diameters are varied so that the hole diameter ratios betweenthe spinning hole pairs are less than 1.5 in the process for themanufacture of fibers with latent curling-shrinking characteristicsby passing a molten polymer at different flow rates through apair of spinning holes having different hole diameters,theinclination of their outlet sides being such that they willcome close to each other,followed by merging,adhering,coolingand coiling.  \n2.  The process described in claim 1 in which the coilingspeed after cooling is more than 3000 m/min.  \n# Detailed explanation of the invention\n\nThis invention relates to a process for the manufacture offibers having latent curling-shrinking characteristics.  \nConventionally,the following processes are known as processesfor the manufacture of fibers having latent curling-shrinkingcharacteristics.  \nOne is a process in which two polymers with differentshrinkage characteristics are merged in an outlet hole to form  \nPage 3  \na composite filament.  However,in this process,not only aredifferent polymers required,but also a complicated compositespinning apparatus is needed,and the spinning operation is alsocomplicated.  Another process is one in which the filament iscooled nonuniformly during spinning.  A complicated apparatusis also required in this process.  In spinning,yarn breakageor the mutual adherence of single yarns is apt to occur.  It isdifficult to obtain high-quality products industrially.  Further-more,there is a process in which a running filament is pressedagainst a knife edge to render an internal strain in the filament.However,this process wil1 cause damage in the filament and isundesirable.  \nIn addition,in recent years,a process for obtaining fiberswith latent curling-shrinking characteristics has been disclosedin Japanese Kokai Patent No.Sho 54[1979]-42415,in which meltsof a fiber-forming polymer moving at two different speeds areallowed to merge and adhere to each other near the surface of  \nthe spinning clasp.  The mechanism for the latent curling-shrinkingdiscovery in this process is the occurrence of vibrations ofmelt streams near the merging point of melt streams moving attwo different speeds.  As a result,a filament having a deniervariation can be obtained.  Since the said filament with thedenier variation has different degrees of shrinkages in thickand thin sections,a filament yarn having curling-shrinkingcharacteristics with the curling-shrinking discovery by heattreatment can be obtained.  In a comparison of this process withthe composite spinning process described above,it has the  \nPage 4  \nadvantages of being a single kind of polymer and requiring nocomplicated spinning apparatus.  However,there is a limit tothe range of variation.  It has a major drawback in that thosefil","cbCaipymLS8f6jvw","https://ap.wps.com/l/cbCaipymLS8f6jvw","pdf",1488274,36,"English","# Claims\n## Claim 1\n## Claim 2\n# Detailed explanation of the invention\n## Background of conventional processes\n## Problems with prior art\n## Summary of the present process\n## Figure reference","[{\"question\":\"What characterizes the claimed process for producing latent curling-shrinking fibers?\",\"answer\":\"It uses multiple pairs of spinning holes with specified diameter ratio relationships, feeds a molten polymer at different flow rates through different hole diameters, and inclines outlet sides so melt streams merge, adhere, cool, and are coiled.\"},{\"question\":\"How are the spinning hole diameters controlled in the invention?\",\"answer\":\"Pairs of spinning holes are arranged so that hole diameter ratios are 1.5–2.5, while the diameter ratio between different hole pairs is set to less than 1.5 to control the process outcome.\"},{\"question\":\"What limitation is specified for coiling speed after cooling?\",\"answer\":\"The second claim requires the coiling speed after cooling to be more than 3000 m/min.\"}]","PROCESS FOR THE MANUFACTURE OF FIBERS WITH LATENT CURLING-SHRINKING CHARACTERISTICS - Claims and Detailed Explanation | PDF",91]
