1. Ngwọta ihe eji eme ihe
• Polyester Chip Drying: Polyester has extremely low hygroscopicity, but excessive moisture content (>0.02%) nwere ike ịgbaji ngwa ngwa ma mebie n'oge a na-atụgharị. A na-eme ihicha na igwe na-ekpo ọkụ na 120-140 degrees maka awa 4-6 iji mee ka mmiri dị n'okpuru 50 ppm.
• Nkwadebe Fiber Viscose: Viscose na-eme agadi, ịcha edo edo, na mgbasa iji mepụta ngwọta ntụgharị (ihe ngwọta viscose nwere cellulose alkali). A na-emezi nzacha na nzacha iji wepụ ihe ndị na-adịghị ọcha na afụ iji hụ na spinnability.

A na-ahazikwa yarn agwakọtara site na oghere, kaadị, ịse, ịkwọgharị, na ntugharị. Usoro a na-enweta ngwakọta nke fiber na-edoghị anya ma dabara adaba maka akwa akwa, mana yana nrụpụta nrụpụta dị ala.
• Siro Spinning/Compact Spinning Optimization: Site n'inye nri rovings abụọ (otu polyester yarn na otu viscose yarn) na ijikọta ha maka ntụgharị, ike yarn na ịdị n'otu na-eme ka ọ dịkwuo mma, na-ebelata ntutu isi, na-eme ka ọ dịkwuo mma maka akwa akwa{0}.
3. Usoro ịkwa akwa

• Ihe kpara akpa: akwa a kpara akpa na-eji akwa larịị, twill, ma ọ bụ satin, na ma nke warp na weft yarn bụ ngwakọta polyester/viscose (dịka, nha 65/35). N'oge a na-akpa ákwà, ekwesịrị ịṅa ntị na ọkụ eletrik static na eriri viscose (nke enwere ike ibelata site na ịmegharị ma ọ bụ ịbawanye iru mmiri na ogbako ahụ ruo 60-70%).
