The operations employed inpacking such staple loose fibers include,(1)compressing thestaple loose fibers under great pressure by a compression devicesuch as a compression piston etc.,(2)applying belts,packingtape etc.to the staple loose fibers in that state for packing,and(3)releasing the pressure imposed by the aforementionedcompression device which compressed the packing of the stapleloose fibers,followed by removal of the package of staple loosefibers from the compression device.  The pressure for compressingthe staple loose fibers in operation(1)varies with the type offibers constituting the staple loose fibers,but it usually is10~40 kg/cm²·Gage.  The pressure imposed on the packaged stapleloose fibers throughout operations(1),(2)and(3)(below termedcompression pressure)is 3~15 kg/cm²·Gage.  The package of stapleloose fibers produced through the aforementioned operations isunpacked at the spinning plant in as early as five days,butusually within two weeks.  \nThe bulk increases greatly due to recovery of resiliencewhen the packing pressure is released upon unpacking of thestaple loose fibers at the spinning plant.  Specifically,uponunpacking,the volume of the staple loose fibers becomes 60~708greater than the volume in the packed state in the summer,and itbecomes 90~1208 of said volume in the winter.  \nHowever,difficulties develop at the spinning plant as thevolume of the staple loose fibers increases after unpacking,including(1)requirement of a large area to store the stapleloose fibers,and(2)difficulty in handling the staple loosefibers.  Thus,it is desirable for the volume of the staple loosefibers not to increase too much upon unpacking.  \nThe inventors have conducted thorough research to reduce thevolume increase of staple loose fibers upon unpacking of packagesof synthetic staple loose fibers at spinning plants in comparisonto conventional cases.  The results of said research haveculminated in this invention.  \nSpecifically,this invention concerns a method of  \nsuppressing the rise in bulk of synthetic staple loose fibersfollowing the unpacking of synthetic fiber staple loose fiberswhich has been compressed and packed in which said staple loosefibers are compressed under heating to a temperature above 40℃but under the secondary transition point,followed by packing.  \nThe synthetic staple loose fibers in the method of thisinvention refers to synthetic staple loose fibers with a  \nsecondary transition point which exceeds 40C.  In particular,polyester fibers,polyvinyl chloride fibers and acrylonitrilefibers are ideal for staple loose fibers.  \nSuch synthetic staple loose fibers in the method of thisinvention must be ","cbCairfU1kshe2We","https://ap.wps.com/l/cbCairfU1kshe2We","pdf",355763,14,"English","# Specifications\n## Detailed Description of the Invention","[{\"question\":\"What problem does the invention address when synthetic staple loose fibers are unpacked?\",\"answer\":\"It addresses the large rise in bulk volume caused by recovery of resilience when packing pressure is released, which leads to storage area requirements and handling difficulties at the spinning plant.\"},{\"question\":\"How does the method suppress the volume increase?\",\"answer\":\"It compresses the synthetic staple loose fibers under heating to a temperature above 40°C but below the secondary transition point, and then packs them.\"},{\"question\":\"Why is heating below 40°C ineffective?\",\"answer\":\"When the compression temperature is under 40°C, the objective of suppressing volume increase upon unpacking is not achieved, and crimping damage can occur, harming spinning properties.\"}]","Method of suppressing rise in bulk of synthetic staple loose fibers upon unpacking - Patent | PDF",1789972311,35]
