[0010]Althoughtheglassfiberinparticularusedforthepresentinventionisnotlimited,glassfibers,suchasEglass,Dglass,Tglass,Cglass,andHglass,arementioned,forexample.Theseglassfiberscouldbemanufacturedinaccordancewiththepubliclyknownmanufacturingmethod,andevenifacommercialitemisusedforthem,theyarenotcaredabout.Especially,especiallyapreferablethingisEglassfiber.

[0014]Asforthewarpwhichpulledanduniformlyalignedtwoormoresinglefibers,andwasformed,itispreferablethatwarpingprocessingisgiven.Thiswarpingprocessingmaybeperformedinaccordancewithapubliclyknownmethod.Themethodshownin Fig.1 ismentionedasonepreferablemodeofthismethod.Forexample,accordingtoanumber,length,width,etc.ofthesinglefiberdesignedtoproduceadesiredglassfiberfabric,thewarpFisrolledroundtothewarper'sbeam67byequaltension.ThiswarpFisdippedinthesizingagent64inthepastebathtub63,thewarpFispulledoutbyfixedtension,theinsideofthesizingagent64ispassed,andthesizingagent64issufficientlyinfiltratedintothewarpF.Subsequently,withthediaphragmroll65,anexcessivesizingagentissqueezedout,anditdriesbythedrypart66,itrollsroundontheweavingroll68forweavingaglassfiberfabric,andwarpingprocessingiscompleted.Althoughacylinderdryerisused,itisnotusuallylimitedinparticulartothedrypart66.
