1. Raw Material Pretreatment
• Polyester Chip Drying: Polyester has extremely low hygroscopicity, but excessive moisture content (>0.02%) inap long 'hydrolyze' na bruk isi tru taim ol i tanim. Ol i save draim long wanpela 'vacuum drum dryer' long 120-140 digri inap 4-6 aua long mekim wara i stap aninit long 50 ppm.
• Wok bilong redim 'Viscose Fiber': 'Viscose' i save kamap lapun, i kamap yelo, na i kapsait na kamapim wanpela 'spinning solution' (wanpela 'viscous solution' we i gat 'alkali cellulose' insait long en). Bihain ol i save mekim 'filtration' na 'degassing' bilong rausim ol pipia na ol 'bubble' bilong mekim ol i ken tantanim. Ol i save miksim 'viscose fiber' olsem ol 'staple fibers' (olsem 'viscose staple fibers'), we longpela bilong en em 38-51 mm na 1.67-2.22 dtex.
2. Spinning Proses
Ol i save wokim ol 'blended yarns' long tupela rot:
• Ring Spinning: Ol i miksim 'polyester staple fiber' na 'viscose staple fiber' wankain (yusim 'manual premixing' o wanpela 'disc blender'). Ol i save opim, kadim, droim, raunim, na tanim tanim. Dispela rot i save kamapim wankain 'fiber blending' na em i gutpela long ol konvensenel laplap, tasol wantaim liklik prodaksen efisiens.
• Siro Spinning/Compact Spinning Optimization: Taim yu givim kaikai long tupela 'rovings' (wanpela 'polyester yarn' na wanpela 'viscose yarn') na bungim tupela long tanim, strong bilong 'yarn' na 'yarn uniformity' i kamap gutpela moa, na tu, i no gat planti gras, na dispela i mekim em i gutpela moa long ol 'high-end fabrics.
3. Rot bilong samapim laplap
Ol 'blended yarns' ol i ken samapim o samapim bihainim kain laplap ol i laik samapim:
• Ol 'Woven Fabrics': Ol 'woven fabrics' i save yusim ol 'plain', 'twill', o 'satin' 'weaves', we tupela 'warp' na 'weft' 'yarns' em i 'polyester/viscose blend' (olsem, 65/35 resio). Taim ol i samapim laplap, ol i mas lukluk gut long pawa we i no save senis insait long ol 'viscose fibers' (we ol i ken daunim sapos ol i 'wax' o apim 'humidity' insait long woksop i go antap long 60-70%).
• Ol 'knitted fabrics': Ol i save wokim long ol 'weft-'knitted circular o flat knitting masin, olsem 'jersey' na 'rib', ol 'viscose fibers' i save yusim sofnes bilong ol long mekim man i werim i fit gut, na ol 'polyester fibers' i save mekim 'loop' i stap gut.
4. Ol bikpela step bilong pinisim
• Disizing na Scouring: Sapos laplap i gat sizing (bilong ol laplap ol i bin samapim), ol i save yusim ol ensaim o alkali ejen bilong rausim ol pipia na ol samting bilong helpim long tanim. Long dispela step, ol i mas bosim 'alkali concentration' bilong ol 'viscose fibers' (Liklik o wankain olsem 5g/L) long abrusim bikpela bagarap.
• Mekim i kamap malumalum na Setim: Ol i save yusim ol samting bilong mekim han i kamap malumalum (olsem ol silikon) bilong mekim han i pilim gut, na taim ol i putim long hai-temperature (180-200 digri inap 20-30 seken) i save strongim 'dimensional stability' bilong 'polyester' na stopim 'viscose fiber' long go liklik tumas (hat 'rate rate' bilong 'viscose' em i klostu 5-8%, taim dispela bilong polyester em i 0.4-0.8% tasol.
• Pasin bilong daim 'polyester': Bikos 'polyester' i nidim bikpela hat na bikpela presa long 'disperse dyeing' (inap 130 digri), taim 'viscose fiber' em i gutpela long 'reactive dyeing' long rum tempereja na nomol presa (60-80 digri), ol i save bihainim tupela -bat rot bilong "daiim 'viscose' pastaim na bihain 'polyester', o ol i save yusim rot bilong 'optimized' rot bilong prosesim long rot bilong 'optimized process'. "wan-bath tu-step rot" (daim 'viscose' long liklik tempereja pastaim na bihain daim 'polyester' long bikpela tempereja).
