Detailed Description of the Invention\n\nThis invention pertains to a process for dyeing polyester fiber products.  \nThe previously available fiber products containing elastic polyesterfilament are,for example,stocking,etc.,made of composite filament comprisingelastic and non-elastic polyester,power net,etc.,made of elastic polyesterfilament and other filaments.However,when those fiber products containingelastic polyester filament were dyed with disperse dye,it was found that thedyeing fastness,especially washing fastness was extrenely poor,and thus,theproducts were not practically usable at all.The shortcoming was especiallysignificant in the medium to dark color.Therefore,the application of fiberproducts containing elastic polyester filament was limited to extremely specificfields,and the development into the application to wide range of clothing wasimpossible.  \nFurthermore,as a method to improve the wet fastness of the polyester fiberproducts dyed with disperse dye","cbCaicnnMgGIQokA","https://ap.wps.com/l/cbCaicnnMgGIQokA","pdf",615415,16,"English","# Request for Examination\n## 1.
