The process first treats polyester fibers with low-temperature plasma using an oxygen-containing gas, then applies polyalkylene glycol (with a stated molecular weight range) at 2–10% by weight relative to fiber weight. The invention targets durable antistatic properties, water absorption, and soil release, addressing shortcomings of conventional treatments that often degrade durability, dye stability, or hand

temperature plasma of a gashat contains oxygen and applying from 2 to 10%by weight periber weight of polyalkylene glycol having a molecular weight ofrom 300 to 2000 to said fibers,said fibers are treated with lowemperature plasma of air,nitrogen,oxygen,argon,etc.  \n# etailed explanation of the invention\n\nThe present invention concerns a method of improving theurface of polyester fibers.The object of the present inventions to propose a method of imparting durable antistatic proper-ies,water absorption properties and soil release properties tooods made-of a polyester fibers.  \nPolyester fibers have excellent properties which includetrength,dimensional stability,wash and wear properties,rapidrying ability,etc.  On the other hand,their uses are limitedy inferior antistatic properties,water absorption propertiesnd soil release properties.For this reason,various attemptsave been made to improve on these drawbacks.  Nonetheless,theroperties obtained are not satisfactory,especially in terms ofheir durability when washed.  For example,even when oneroperty is satisfactory(e.g.antistatic property),otherroperties are poor(e.g.soil release property)·Or,onlynsatisfactory performance can be obtained because of negativeffects on the dye stability and feel.  \nPage 3  \nConventional methods of improving these drawbacks includebsorbing or adsorbing hydrophilic substances to the surface ofhe polyester fibers or fi1m formation through utilization ofrosslinked bonds between the substances.Another method israft polymerization of a polymeric monomer having hydrophilicroups to the surface of the fibers.Still,all of these methodsave the aforementioned drawbacks.Despite ongoing studies onmprovement,satisfactory techniques have not been obtained toate.Attempts have recently been made to improve the surface oflyester fibers by low temperature plasma treatment in additionthe aforementioned methods.  This is an extremely interestingethod,but it is far from being a perfect method because thentistatic properties are not improved despite the possibility ofnproving the water absorption and soil release properties of thelyester fibers by this technique.  \nAs a result of diligent studies intended to resolve suchroblems,the present inventors discovered that satisfactoryntistatic properties,water absorption properties and soilelease properties with excellent durability can in fact bebtained by a combination of low temperature plasma treatment oflyester fibers and application of a specific concentration oflyalkylene glycol with a molecular weight within a specificange to said polyester fibers.  The present invention wastained on the basis of this discovery.  \nSpecifically,the present invention is a method of improvinglyester fibers wherein after treating polyester fibers with lowemperature plasma of an oxygen-containing gas and apply","cbCaiic023L5awtx","https://ap.wps.com/l/cbCaiic023L5awtx","pdf",1254904,44,"English","# Method of Improving Polyester Fibers\n## Detailed explanation of the invention","[{\"question\":\"What are the key goals of the method for polyester fibers?\",\"answer\":\"The method aims to impart durable antistatic properties, water absorption properties, and soil release properties to goods made of polyester fibers.\"},{\"question\":\"How does the method treat the polyester fibers?\",\"answer\":\"It uses low-temperature plasma of an oxygen-containing gas, followed by application of polyalkylene glycol within a specified concentration range based on fiber weight.\"},{\"question\":\"Why are conventional improvement techniques not satisfactory?\",\"answer\":\"Conventional approaches can produce uneven results—improving one property while leaving others poor—and may also fail durability after washing or negatively affect dye stability and feel.\"}]","METHOD OF IMPROVING POLYESTER FIBERS - Detailed explanation of the invention | PDF",1789972163,111]
