1. Raw Material Pretreatment
• Polyester Chip Drying: Polyester has extremely low hygroscopicity, but excessive moisture content (>0.02%) inogona nyore hydrolyze uye kutyora panguva yekutenderera. Kuomesa kunoitwa muvacuum drum dryer pa120-140 dhigirii kwe4-6 maawa kuchengetedza hunyoro huri pasi pe50 ppm.
• Viscose Fiber Preparation: Viscose inochembera, yero, uye yakanyunguduka kuti igadzire mushonga wekutenderera (a viscous solution ine alkali cellulose). Kusefa uye degassing kunobva kwaitwa kubvisa tsvina uye mabhubhu kuti ive nechokwadi che spinnability. Viscose fiber inowanzosanganiswa mumhando ye staple fibers (yakadai se viscose staple fibers), ine urefu hwe 38-51 mm uye fineness ye 1.67-2.22 dtex.
2. Spinning Process
Shinda dzakasanganiswa dzinogadzirwa kunyanya nenzira mbiri:
• Ring Spinning: Polyester staple fiber uye viscose staple fiber zvinosanganiswa zvakafanana (uchishandisa manual premixing kana disc blender). Shinda yakasanganiswa inozogadziriswa kuburikidza nekuvhura, makadhi, kudhirowa, kutenderera, uye kuruka. Iyi nzira inowana yakanyanya yunifomu faibha kusanganisa uye inokodzera machira akajairwa, asi nekushomeka kwekugadzira.
• Siro Spinning/Compact Spinning Optimization: Nekupa ma rovings maviri (shinda imwe yepolyester neshinda imwe yeviscose) nekuabatanidza kuti amonere, kusimba kweshinda nekufanana kweshinda kunonatsiridzwa, ukuwo kuchideredza hubvudzi, zvichiita kuti anyanye kuenderana ne-machira ekupedzisira.
3. Kuruka Maitiro
Shinda dzakasanganiswa dzinogona kurukwa kana kurukwa zvichienderana nerudzi rwejira rakanangwa:
• Micheka Yakarukwa: Micheka yakarukwa inoshandisa plain, twill, kana satin weave, uye shinda inochinjika neyeweft iri musanganiswa wepolyester/viscose (semuenzaniso, reshiyo ye65/35). Munguva yekuruka, kutarisisa kunofanirwa kubhadharwa kune static magetsi mune viscose fibers (iyo inogona kuderedzwa newakisi kana kuwedzera hunyoro mumusangano kusvika 60-70%).
• Machira akarukwa: Anowanzo gadzirwa pamichina yakarukwa{{0}yakarukwa yedenderedzwa kana yakafuratira, sejezi nembabvu, mafirita eviscose anoshandisa kupfava kwawo kuti awedzere kukwana kweanoapfeka, ukuwo mafiinzi epolyester anoita kuti loop igare.
4. Makiyi Ekupedzisa Matanho
• Desizing and Scouring: Kana jira racho riine saizi (yemachira akarukwa), maenzayimu ekugadzira kana alkali agents anoshandiswa kubvisa kusvibiswa kwechisikigo uye kuruka zvinotsigira. Munguva iyi, iyo alkali concentration yeviscose fibers inofanirwa kudzorwa (Zvishoma pane kana kuenzana ne5g/L) kudzivirira kukuvadzwa kwakanyanya.
• Kupfava uye Kuseta: Mapadding softeners (akadai sesilicones) anoshandiswa kunatsiridza kunzwa kweruoko, ukuwo-tembiricha yakakwira (180-200℃for 20-30 seconds) inodzikamisa polyester's dimensional kugadzikana uye inodzivirira kuderera kwakanyanya kweviscose fiber (iyo chiyero cheheat 5 chepolyester inosvika 58% yeheat shrinkage. chete 0.4-0.8%).
• Diyeing process: Nekuti polyester inoda tembiricha yakakwira uye high pressure disperse dyeing (inenge 130 degree), ukuwo viscose fiber inokodzera reactive dyeing pakamuri tembiricha uye normal pressure (60-80 degrees ), maviri-nzira yekugezera "yekufa viscose kutanga kozoti polyester" inowanzoitwa oneth{4} process, or the processed through two nzira" (kufara viscose pane yakaderera tembiricha kutanga uye ipapo dhayi polyester pane yakakwirira tembiricha).
